RS EVA-53: Good morning; cosmonauts Oleg Artemyev and Denis Matveev are suited up for a planned 6.5-hour EVA, the second in a series to outfit the European Space Agency robot arm mounted on the multi-purpose Nauka module; the EVA is expected to begin ~10:25am EDT (1425 UTC)

RS EVA-53: This will be the 250th EVA in ISS history, the 5th so far this year, the 3rd by the Russians, the 5th for Artemyev and the 2nd for Matveev; today's EVA comes 10 days after a 4/18 spacewalk by Artemyev and Matveev to begin outfitting the ERA robot arm

RS EVA-53: The European Robotic Arm stretches 37 feet when fully extended and is equipped with grapple fixtures on each end; like the station's Canadian arm, the ERA can move inchworm fashion, from base plate to base plate, to reach different work sites

RS EVA-53: In today's EVA, the crew will remove insulation and launch locks, allowing the arm to move for the first time, translating from its folded launch config to different base plates, a so-called "hibernation" configuration; extensive testing planned along the way

RS EVA-53: NASA TV coverage of today's spacewalk is underway with commentator Rob Navias following along in mission control at the Johnson Space Center:

RS EVA-53: Running about a half hour behind schedule, Artemyev and Matveev opened the side hatch of the Poisk module at 10:58am EDT (1458 UTC) to officially begin today's spacewalk

RS EVA-53: For ID, Artemyev is using the call sign EV-1 and is wearing Orlan-MKS suit 5 with red stripes; Matveev, EV-2, is using MKS 4 with blue stripes; both men are equipped with NASA high-def EVA camera assemblies (HECAs) and low-def helmetcams (16 & 20 respectively)

RS EVA-53 (PET: 24:15; EDT: 11:22am): Artemyev and Matveev are now moving from Poisk to the Nauka module where the European Robotic Arm awaits

RS EVA-53 (PET: 1:40; EDT: 12:38pm): The cosmonauts are working to remove and bundle up thermal insulation from the robot arm assembly before jettisoning the blankets and wire ties; also releasing launch locks; spectacular views today from USOS high-def cameras

RS EVA-53 (PET: 1:48; EDT: 12:46): Artemyev has jettisoned the bundled up robot arm insulation; TV views showed the wad of wire-tied blankets slowly drifting away behind the space station, jettisoned in a direction to preclude recontact during subsequent orbits

RS EVA-53 (PET: 2:19; 01:17pm EDT): Sergey Korsakov, inside the ISS, is preparing to send commands from a control panel that will release one end of the European robot arm so a joint can rotate the end effector outward for installation of a handrail, more launch lock releases

RS EVA-53 (PET: 2:58; 1:56pm EDT): Still awaiting the wrist joint outward rotation

RS EVA-53 (PET: 3:09; 2:07pm EDT): One end of the arm has rotated outward slightly as planned; Artemyev and Matveev have released actuators enabling the grappling mechanism on that end of the arm to firmly grip various objects in the future

RS EVA-53 (PET: 4:05; 3:03pm EDT): The arm's wrist and elbow joints are working properly; the cosmonauts are installing another three handrails before end effector No. 2 "walks off," moves to another base plate and locks itself down

RS EVA-53 (PET: 4:22; 3:20pm EDT): One end of the European robot arm has walked off its launch mount, extending away from the Nauka module like an actual appendage; after it locks onto a different base plate the other end of the arm will walk off and relocate on another base

RS EVA-53 (PET: 5:30; 4:28pm EDT): Russion flight controllers confirm ERA end effector No. 2 is firmly locked onto its designated base plate; Artemyev, meanwhile, is inspecting a KURS antenna that did not fully deploy during the Soyuz MS-21 docking in March

RS EVA-53 (PET: 5:40; 4:38pm EDT): Artemyev moved a snarled cable, which apparently prevented a KURS antenna from fully deploying on the Prichal module after launch, forcing him to take over manual control during the MS-21 docking 3/18

RS EVA-53 (PET: 6:03; 5:01pm EDT): ERA end effector No. 1 is on the move, heading for another base plate as part of the robot arm's double walk off maneuve

RS EVA-53 (PET: 6:15; 5:13pm EDT): A nice view of the European Robotic Arm inch-worming its way to another base plate

RS EVA-53: Artemyev and Matveev just unfurled a commemorative bright red Soviet flag to mark World War II "Victory Day" in Russia

RS EVA-53 (PET: 7:03; 6:01pm EDT): Passing the 7-hour mark, Sergey Korsakov, inside the space station, jokingly called out for dinner orders from Artemyev and Matveev; waiting for word on whether a 3rd ERA walk-off is planned after end effector #1 finishes grappling a base plate

RS EVA-53 (PET: 7:22; 6:20pm EDT): Artemyev and Matveev are stowing tools and equipment in the Poisk module while flight controllers monitor the final steps in a robot arm maneuver, locking end effector #1 onto a base plate; if no problems, the EVA will end in a few minutes

RS EVA-53 (PET: 7:38; 6:36pm EDT): The robot arm end effector is not yet locked in place, but Artemyev and Matveev are both back in the Poisk airlock compartment, checking tools, tethers and readying the hatch for closure

RS EVA-53: The cosmonauts closed the Poisk hatch at 6:40pm EDT (2240 UTC) to officially close out a 7h 42m EVA; Sergey Korsakov now plans to press ahead with commanding the European Robotic Arm to complete the multi-joint space crane's second walkoff

RS EVA-53: Total ISS EVA time now stands at 1,583 hours and 44 minutes; Artemyev has logged 34 hours 39 minutes during 5 spacewalks while Matveev's total is 14 hours and 19 minutes over 2 EVAs

RS EVA-53: To cross the final t and dot the final i, the European Robotic Arm completed its 2nd walk off after today's spacewalk ended, latching onto the designated base plate to firmly anchor the multi-joint appendage as planned

Long March-2C launches Siwei-01 and Siwei-02

China launches two new satellites
Xinhua | Updated: 2022-04-29 13:09   

JIUQUAN -- China successfully sent two satellites into space from the Jiuquan Satellite Launch Center in Northwest China on Friday.

The satellites, Siwei 01 and 02, were launched by a Long March 2C carrier rocket at 12:11 pm (Beijing Time) and have entered the planned orbit.

They will provide commercial remote sensing data services for industries including surveying and mapping, environmental protection, as well as urban security and digital rural development.

The launch marked the 417th flight mission of the Long March series carrier rockets.

China launches pair of commercial remote sensing satellites, sea launch scrubbed

HELSINKI — A Long March 2C rocket sent a pair of optical remote sensing satellites into orbit early Friday to provide commercial remote sensing imagery.

The Long March 2C lifted off from Jiuquan Satellite Launch Center in the Gobi Desert at 12:11 a.m. April 29, placing the Siwei-01 and 02 satellites into their planned sun-synchronous orbits.

U.S. space tracking later detected the pair in 486 by 502-kilometer orbits inclined by 97 degrees.

The satellites, also known as Superview Neo-1 01 and 02, each have a mass of around 540 kilograms and will deliver 0.5-meter resolution optical imagery.

The satellites will provide commercial remote sensing data services for traditional satellite data customer industries including natural resources, surveying and mapping and marine and environmental protection, as well as emerging markets including urban security, digital rural development and smart agriculture and transport, according to Chinese media.

The pair was developed by the China Academy of Space Technology (CAST), a major subsidiary of the China Aerospace Science and Technology Corporation (CASC), the country’s main space contractor and giant state-owned defense enterprise.

The satellite operator, China Siwei Surveying and Mapping Technology Co., Ltd, is also a CASC subsidiary. The company also operates two pairs of co-planar “Gaojing” or Superview satellites launched in December 2016 and January 2018, delivering panchromatic 0.5-meter resolution imagery.

China also has a commercial Earth observation firm in the shape of Changguang Satellite Technology. The Changchun-based remote sensing constellation operator is a well-backed spinoff from the Chinese Academy of Sciences’ CIOMP, and has launched more than 30 Jilin-1 series optical and video satellites, with panchromatic resolution of around 0.70 meters.

The Friday launch was China’s 12th of 2022, in which CASC plans more than 50 launches. Launch attempts from commercial actors including Landspace, Expace, Galactic Energy and more are expected to add to the activity.

The planned April 29 launch of a Long March 11 solid rocket from a platform in the East China Sea was scrubbed because of weather.

A new attempt is set for early April 30 universal time. The flight path will take the rocket over Taiwan, with spent stages to fall into the seas.  It is expected to deliver new Jilin-1 satellites into orbit.

China has developed infrastructure at Haiyang, Shandong province to allow launches from the seas. The capabilities may help ease congestion at other national spaceports and reduce debris falling near inhabited areas following inland launches.

(...) Two Chinese rockets, including one launched from an ocean-going platform in the East China Sea, deployed seven optical Earth-imaging satellites in a pair of successful missions last week.

The missions Friday and Saturday were the 12th and 13th Chinese space launches of the year, continuing a schedule of rocket flights deploying military satellites and payloads for China’s flourishing commercial space industry. (...)

The satellites, also known as SuperView Neo 1-01 and 1-02, will take optical images at a resolution of a half-meter, or about 1.6 feet, for purchase by commercial clients, serving many of the same applications as the Jilin 1 constellation

The U.S. military catalogued nine objects in orbit from the Long March 2C mission, more than the expected number of three objects, including the two Siwei satellites and the Long March rocket’s upper stage.

But the identities of the additional objects were not immediately known. The objects could be debris or undisclosed payloads that accompanied the Siwei satellites into orbit.

Long March-11 launches five Jilin-1 satellites

China launches 5 satellites for Earth observation from East China Sea
Updated 11:39, 01-May-2022 CGTN

China sent five satellites into orbit aboard a Long March-11 carrier rocket at 11:30 a.m. on Saturday (BJT) from a platform in the East China Sea.

The new Earth-observation satellites have since successfully entered their predetermined orbit, and will provide commercial service for natural resource surveys, urban planning, disaster monitoring and other tasks.

They are part of the Jilin-1 Gaofen satellite series – gaofen is an abbreviation for "high resolution" in Chinese – which is expected to have 138 satellites by 2025 and become the largest commercial observation constellation in China.

This launch also represented the 418th of China's Long March rocket series.

Most rocket launches are carried out on land, but sea-based rocket launch technology is vital for China's space program as it provides more flexibility and safety for spacecraft launches. /CMG

Sea launch safer and more flexible

This was China's third sea-based launch mission, as the country seeks to further expand the maneuvering range of maritime launches and accumulate technological expertise for future long-distance sea-based launch missions.

Most rocket launches are carried out from land, but sea-based rocket launch technology is vital for China's space program as it provides more flexibility and safety for spacecraft launches, Dong Xiaobin, deputy director of the Long March-11 rocket project at the China Academy of Launch Vehicle Technology (CALT), told China Media Group (CMG).

Different launch locations are better suited to different types of spacecraft to get into the orbit, and China's long coastline provides plenty of sites for sea-based launches.

"We can choose the launch site more flexibly according to the requirements of the mission so that we can make full use of the rocket's lifting capacity. Also, if it is a sea launch, we can ensure that all the rocket debris falls into the sea through ballistic design," said Dong. This makes such launches safer for people on land.

Sea launches can make full use of China's rich marine resources, boosting the development of aerospace technology and marine engineering. /CMG

Perfect match of space tech & marine resources

Sea-based launches can also make full use of China's rich marine resources, boosting the development of aerospace technology and marine engineering.

The floating platform for Saturday's launch used to be a semi-submersible barge.

After modification, the platform, which is larger than a standard football pitch, became home to carrier rockets, satellites and supportive equipment, including a temperature-controlled cabin for the satellites.

"The temperature-controlled cabin here is to ensure that the satellites stay in a comfortable environment. Although the sea (environment) has high humidity with salt spray, the satellites are placed in a very good environment," Zhang Ming, deputy chief designer of the Long March-11 rocket project at CALT, told CMG.

The control center of the sea-based launch mission -- from which scientists and engineers monitored the whole launch -- was also at sea, located on a separate ship about three kilometers from the launch platform.

"The control room provides an integrated space for the rocket's control, command and monitoring systems, contributing to the success and smooth launch of the rocket," said Liu Yaguang, chief designer of Long March-11 rocket control system at CALT.

(...) The payloads included four Gaofen 03D-class optical imaging satellites and the first in a new generation of Gaofen 04 remote sensing satellites, according to the China Aerospace Science and Technology Corp., or CASC, the largest Chinese state-owned enterprise overseeing the country’s space industry.

The satellites are designed to capture high-resolution optical images and video, collecting data for use across a range of applications, including forestry, agriculture, ocean monitoring, resource and environmental surveys, and urban planning, CASC said in a statement.

More than 40 Earth-imaging satellites, typically about the size of a microwave oven or a mini-refrigerator, have launched in the Jilin 1 constellation since 2015. (...)

The launch marked the 13th flight of a Long March 11 rocket, and the third to blast off from a sea-based platform. The four-stage Long March 11 is sized for small satellite missions. It burns solid propellant, and is based on Chinese ballistic missile technology.

CASC said there are one to three sea-based Long March 11 launches scheduled this year.

The Long March 11 launch followed less than 24 hours after the blastoff of a liquid-fueled Long March 2C rocket from the Jiuquan space center in the Gobi Desert of northwestern China. (...)

China launched eight more microsatellites for the Jilin 1 high-resolution Earth observation constellation May 4, five days after a separate mission deployed five similar Jilin 1 payloads into orbit.

The launches signal an uptick in the pace of satellite deployments for the Jilin 1 constellation, a fleet of small remote sensing satellites developed by Chang Guang Satellite Technology Co. Ltd., a commercial remote sensing company based in China’s Jilin province.

The Jilin 1 fleet is aimed at serving commercial users of Earth imaging data, including urban planners and infrastructure developers and the mining, agriculture, forestry, and maritime industries.

Eight satellites for Chang Guang launched May 4 at 10:38 p.m. EDT (0238 GMT on May 5) aboard a Long March 2D rocket, according to the China Aerospace Science and Technology Corp., or CASC, the largest state-owned enterprises overseeing China’s space industry.

Heading south from the Taiyuan launch base in northern China, the two-stage Long March 2D rocket dropped its first stage over Chinese territory a few minutes after liftoff. A second stage deployed the eight payloads into a near-circular polar orbit with an average altitude of around 334 miles (538 kilometers), at an inclination of about 97.7 degrees to the equator, according to tracking data published by the U.S. military.

The payloads included the Jilin 1 Kuanfu 01C optical wide-area imaging spacecraft, plus seven Jilin 1 Gaofen 03D-class high-resolution optical observation satellites. The mission was managed by China Great Wall Industry Corp., a subsidiary of government-owned CASC responsible for booking rides on Chinese Long March rockets for commercial payloads.

More than 50 Earth-imaging satellites, typically about the size of a microwave oven or a mini-refrigerator, have launched in the Jilin 1 constellation since 2015.

Sixteen Jilin 1 satellites have launched this year. Most recently, five Jilin 1 satellites lifted off April 29 on a Long March 11H rocket launched from an ocean platform in the East China Sea.

WENCHANG, Hainan, May 7 (Xinhua) -- China has for the first time realized the fine forecast of Earth's near-surface wind for a major space launch mission, according to the Xichang Satellite Launch Center.

The fine forecast system for wind in key areas of the near-surface layer has been applied to ensure the transfer of the combination of the Tianzhou-4 cargo spacecraft and the Long March-7 Y5 carrier rocket to the launching area of the Wenchang Spacecraft Launch Site, the center said.

The system was developed by the meteorological tech support team of the center to overcome challenges from the Earth's near-surface wind, which has a great impact on the smooth vertical transfer of spacecraft and rockets.

As the rocket has not been filled with fuel before being transferred to the launch site, it is easily affected by wind, especially in the coastal regions, which makes the precise forecast of near-surface wind very important for the transfer.

Located in south China's Hainan Province, the Wenchang Spacecraft Launch Site is the country's fourth launch site and the only one by the seaside.

The forecast system can provide real-time visual weather forecasts based on the latest meteorological information of the near-surface wind, with three-dimensional simulation images as well as change parameters of wind power and direction.

The system has been developed since 2018, and it passed the final inspection and acceptance in April this year.

According to the Xichang Satellite Launch Center, the new forecast system performed well during its first application in the transfer mission of Tianzhou-4 and Long March-7 Y5.

Its forecast precision is within one meter and it has played an important role in enhancing the meteorological forecast capabilities of the Wenchang Spacecraft Launch Site, the center said.

The Tianzhou-4 cargo spacecraft will be launched in the near future at an appropriate time, according to the China Manned Space Agency.

WENCHANG, Hainan, May 10 (Xinhua) -- China launched cargo spacecraft Tianzhou-4 on Tuesday to deliver supplies for its space station, which is scheduled to wrap up construction this year.

The Long March-7 Y5 rocket, carrying Tianzhou-4, blasted off at 1:56 a.m. Beijing Time from the Wenchang Spacecraft Launch Site in the southern island province of Hainan, according to the China Manned Space Agency.

After around 10 minutes, Tianzhou-4 separated from the rocket and entered its designated orbit. At 2:23 a.m., the solar panels of the cargo craft unfolded and began working.

At 8:54 a.m., Tianzhou-4 completed a computer-orchestrated rendezvous and docking at the rear docking port of the Tianhe core module.

On April 20, the Tianzhou-3 cargo craft separated from the rear docking port of Tianhe and docked with its front docking port.

Following Tianzhou-4's docking, the two cargo crafts are docked at the two ends of the Tianhe core module to form a linear shape, waiting for the arrival of the Shenzhou-14 crew members.

Measuring 10.6 meters in length and with a maximum diameter of 3.35 meters, the Tianzhou-4 cargo ship carries around 6 tonnes of goods and materials and 750 kg of propellant for the space station complex.

Like previous cargo flights, Tianzhou-4 mainly carries three categories of supplies, including six-month living supplies for the Shenzhou-14 mission's three astronauts, spare parts for space station maintenance, and space research equipment and sample materials, said Bai Mingsheng, chief designer of Tianzhou cargo craft from the China Academy of Space Technology.

He said Tianzhou-4's carrying capacity of dry cargo increased by 300 kg than the previous cargo ships. Meanwhile, based on the astronauts' in-orbit living and working experience, the team made some tweaks to the cargo storage, providing more convenience for the astronauts in detail.

For instance, different supplies have colored tags, such as green for food, so astronauts can quickly identify the parcels.

Bai said equipment for three research projects also arrived at the space station with Tianzhou-4 and they were selected from across China.

China plans to complete the in-orbit construction of its space station by the end of 2022, and a total of six missions are planned for this year.

Following the launch of Tianzhou-4, the Shenzhou-14 crewed spacecraft will arrive in June, the lab module Wentian in July, the lab module Mengtian in October, and then the Tianzhou-5 cargo craft and the Shenzhou-15 crewed spaceship later this year.

The two lab modules and the core module will form a T shape to complete the in-orbit construction of China's space station.

Tuesday's launch is the 22nd mission of China's manned space programs and the 420th mission of the Long March rocket series. ■

Pierwsza chińska porażka w tym roku z użyciem początkującej rakiety.

Nieudany starty Hyperboli
  13.05. o 07:09 z wyrzutni LC-43/95B w Jiuquan wystrzelona została RN Shuang Quxian-1 (SQX-1, Hyperbola-1).
Miała ona wynieść na orbitę heliosynchroniczną satelitę teledetekcyjnego Jilin-1 Mofang-01A (R). Start zakończył się niepowodzeniem, prawdopodobnie nie doszło do zapłonu silnika drugiego stopnia.

The failure was allegedly due to gas leak in attitude & orbit control system. Not confirmed by i-Space.

Launch of China's commercial carrier rocket fails
Source: XinhuaEditor: huaxia 2022-05-13 21:35:15
JIUQUAN, May 13 (Xinhua) -- The launch of the fourth SQX-1 commercial carrier rocket on Friday was unsuccessful.

Abnormal performance was identified during the flight of the rocket, which lifted off from the Jiuquan Satellite Launch Center in northwest China at 3:09 p.m. (Beijing Time).

The cause of the failure is under investigation, the launch center said in a statement. ■

Chinese rocket company suffers third consecutive launch failure
by Andrew Jones — May 13, 2022

HELSINKI — An orbital launch attempt by Chinese startup iSpace suffered failure early Friday, following on from two failures last year. (...)

The mission was the 16th orbital launch attempt from China in 2022. It was the first launch not relying on a Long March rocket and the first failure.

The loss of what was expected to be a new remote sensing satellite for a commercial satellite developer and operator will be a blow to iSpace’s plans.

Beijing-based iSpace became the first Chinese company from outside of the state-owned, traditional space sector to successfully launch a satellite into orbit in July 2019. The firm suffered two subsequent failures in February and August of last year however.  (...)

Rosyjski satelita zwiadowczy
  19.05.2022 o 08:03:32,331 z Plesiecka wystrzelona została RN Sojuz-2.1a, która wyniosła w T+8' na orbitę o parametrach: hp=337 km, ha=557 km, i=97,70° trzeci egzemplarz wojskowego satelity zwiadu elektrooptycznego typu Bars-M (Lampart). Dostał on nazwę oficjalną Kosmos 2556.

Russia successfully launches Soyuz space rocket

Пуск ракеты-носителя «Союз-2» со спутником «Космос-2556» 19 мая

Russian spy satellite launched by Soyuz rocket
May 23, 2022 Stephen Clark

A classified mapping satellite rode a Soyuz rocket into space Thursday from the Plesetsk Cosmodrome, the fifth mission of the year to deploy a Russian military payload in orbit.

The Russian military satellite launched at 4:03 a.m. EDT (0803 GMT) Thursday from Plesetsk, a military spaceport about 500 miles (800 kilometers) north of Moscow in Arkhangelsk Oblast.

A Soyuz-2.1a rocket began its vertical climb away from Plesetsk with nearly a million pounds of thrust from kerosene-fueled engines, then headed north to target a polar orbit for deployment of its Russian military payload.

The Soyuz jettisoned its four first stage boosters about two minutes into the flight, then a third stage engine took over from the rocket’s core stage about five minutes after liftoff. The third stage deployed its payload into a preliminary orbit ranging in altitude between 210 miles (338 kilometers) and 345 miles (556 kilometers), with an inclination of 97.7 degrees to the equator, according to U.S. military tracking data.

The circumstances of Thursday’s launch — its launch site, the configuration of its launch vehicle, and target orbit — suggest the payload was the Russian military’s third Bars-M digital mapping satellite. The first two spacecraft in Russia’s current generation of Bars-M mapping satellites launched on Soyuz rockets in 2015 and 2016.

The Russian Defense Ministry did not identify the satellite launched Thursday. The Russian military declared the launch successful, and U.S. tracking data confirmed the Soyuz placed its satellite payload into an orbit matching those of the previous Bars-M missions.

Made by TsSKB Progress in Samara, Russia, the Bars-M satellite’s capabilities are classified, but analysts believe it hosts a digital imager, replacing older satellites that carried film cameras that returned to Earth via parachute to be recovered and developed.

The Bars-M satellite’s Karat electro-optical camera was developed by the Leningrad Optical Mechanical Association, and the satellite is expected to operate at least five years, according to documents posted on a Russian government procurement website.

The upgrade allows the Bars-M satellites to remain in orbit longer and send imagery to analysts via radio links.

The last of the old-generation satellites launched in 2005, leaving Russia with a gap in the imaging capability to be filled by Bars-M, which specializes in collecting stereo images to help create maps for use by the Russian military.

The spacecraft launched Thursday was designated Kosmos 2556, continuing the Russian naming scheme for military satellites.

The mission Thursday was the seventh launch of a Soyuz rocket this year, and the fifth space mission to blast off from Plesetsk in 2022.

Starliner OFT-2 (1)
« Odpowiedź #9 dnia: Maj 12, 2022, 07:05 »
A5/OFT-2: United Launch Alliance is hauling an Atlas 5 rocket and Boeing's Starliner crew capsule out to pad 41 at the Cape Canaveral Space Force Station for launch Thursday on an unpiloted test flight to the International Space Station

A5/OFT-2: Liftoff is set for 6:54pm EDT (2254 UTC) Thursday and if all goes well, the Starliner will dock at the ISS at 7:10pm EDT Friday; this will be Boeing's 3rd attempt to get the capsule to the ISS after frustrating hardware and software glitches that took >2 years to fix

A5/OFT-2: The Atlas 5 and the Starliner crew capsule completed the 1,800-foot trip to launch pad 41 at the Cape Canaveral Space Force Station at 11:12am EDT, setting the stage for launch Thursday on a high-stakes test flight to the International Space Station; ULA photo:

The ISS crew was told this afternoon that a "pre-determined debris avoidance maneuver," or PDAM, is being considered for Thursday to steer clear of a piece of space junk; the debris in question was not identified

"We are tracking a red conjunction unfortunately," mission control radioed during a daily planning conference. "So we are looking into doing a PDAM approximately 5 to 6 hours prior to the OFT-2 (Starliner) launch tomorrow. So stay tuned for more on that excitement"

The maneuver, if ongoing tracking confirms it's necessary, is not expected to impact the Thursday launch and Friday docking of Boeing's Starliner capsule

The debris that may prompt an ISS avoidance maneuver Thursday is from the Russian ASAT test last 11/15 that destroyed a defunct satellite, officials confirm; more tracking data is expected overnight that should determine whether an avoidance maneuver is necessary or not

In the meantime, NASA confirms an avoidance maneuver, if necessary, won't impact Boeing's Starliner launch Thursday evening, "but might slightly alter the timing of some of the rendezvous maneuvers leading to Starliner's docking to the station"

Additional tracking shows a piece of debris from a defunct Russian satellite destroyed in an ASAT test last November doesn't pose a threat to the International Space Station; as a result, no debris avoidance maneuver will be required today

A5/OFT-2: Good morning; the countdown is underway for today's planned launch of Boeing's Starliner crew capsule atop a ULA Atlas 5 rocket on LC-41 at the Cape Canaveral SFS; there are no known issues and weather appears favorable for liftoff at 5:54:47pm EDT (2147 UTC)

A5/OFT-2: The countdown began at 7:34am (1134 UTC) at the L-minus 11h 20m (T-minus 6h 20m) mark; a 1-hour hold is expected begin at 11:54am with a final 4-hour hold starting at 2:50pm; NASA TV coverage will begin at 6pm (2200 UTC)

A5/OFT-2: Due to an apparent time zone brain freeze, I mistakenly said earlier the Atlas 5/Starliner launch was targeted for 5:54:47pm EDT; it is, of course, set for 6:54:47pm (2247 UTC); apologies for the oversight

A5/OFT-2: The Atlas 5 countdown entered a planned 1-hour hold at the T-minus 2-hour mark at 11:54am EDT (1554 UTC); when the count resumes at 12:54pm, ULA will begin loading cryogenic propellants; meanwhile, weather is 80% go

A5/OFT-2: The countdown resumed at the T-minus 2-hour mark at 12:54pm (1654 UTC); the team is preparing to load liquid oxygen into the Centaur 2nd stage, followed by 1st stage LOX load (the 1st stage is already loaded with RP-1 fuel); Centaur hydrogen loading will begin shortly

A5/OFT-2: Centaur liquid hydrogen loading is underway; no problems reported so far in today's countdown

A5/OFT-2: Boeing confirms the Starliner service module oxidizer valves have completed their 7th and final pre-launch cycling test, a welcome indication of corrosion-free performance; they'll be cycled open about 30 minutes before liftoff

A5/OFT-2: Today's countdown remains in a planned hold at the T-minus 4-minute mark while United Launch Alliance works through its normal pre-launch timeline; weather is now 90% go; no known problems being worked

A5/OFT-2: Now 1 hour to launch; Starliner's hatch has been closed for flight and the white room crew has completed leak checks

A5/OFT-2: The white room closeout crew, or Blue Team, has finished its work and is leaving the launch pad; the Starliner is now pressurized for flight; the countdown will resume at the L-minus 4-minute mark at 6:50:47pm EDT (2250 UTC)

A5/OFT-2: Management poll complete; all systems 'go' for launch! Countdown resumes in 2 minutes

A5/OFT-2: The countdown has resumed at the L-minus 4-minute mark

A5/OFT-2: LIFTOFF! At 6:54:47pm EDT (2254 UTC)

A5/OFT-2: The Atlas 5 is arcing away to the northeast, launching directly into the plane of the space station's orbit; the vehicle is now supersonic and past the region of maximum aerodynamic stress

A5/OFT-2: Both AJ-60A strap-on solid-fuel boosters have consumed their loads of propellant and have fallen away as planned; the flight is continuing on the 860,200-pound thrust of the venerable RD-180 main engine

A5/OFT-2: 1st stage engine shutdown and stage separation; both hydrogen-fueled RL10A-4 engines powering the 2nd stage have ignited to continue the climb to space; this is a planned 7-minute 5-second burn (predicted)

A5/OFT-2: A view of launch from the roof of the CBS bureau at the Kennedy Space Center

A5/OFT-2: Centaur engine shutdown; Starliner separation expected in about 3 minutes

A5/OFT-2: Starliner separation confirmed; the capsule will now coast for about 16 minutes (predicted) before the orbit insertion (OI) burn in 15 minutes to put the craft in an initial orbit that will set up a 24-hour rendezvous with the ISS

A5/OFT-2: Nominal orbit insertion burn confirmed; the Starliner is now on course while flight controllers set up for a series of "demo" tests to verify maneuvering capability, commanding, VESTA vision system performance and ISS crew commanding

A5/OFT-2: Good OI burn confirmed; the OI burn did not go off on time during the Starliner's initial flight test in December '19 due to a software error; an unrelated comms issue prevented a quick fix and the ISS rendezvous had to be called off; but the burn today was flawless

A5/OFT-2: In a post-launch briefing, Boeing VP Mark Nappi said 2 Starliner OMACS thrusters failed off, sequentially, during the orbit insertion burn; the flight software switched to a 3rd thruster in that pod and the OI burn was completed as planned

A5/OFT-2: No impact yet, but engineers will review telemetry to determine exactly what triggered the shutdowns and whether the thrusters can be recovered; 3 such aft-facing OMAC jets are mounted in each of 4 "doghouse" pods and the rest are working normally

A5/OFT-2: Commercial Crew Program Manager Steve Stich the Starliner should be able to complete the mission even if the 2 OMAC thrusters can't be recovered; only 3 more OMAC burns are planned before docking Friday (3:13pm EDT, 3:35pm and 4pm) and again for the de-orbit burn

A5/OFT-2: Stich: "Overall, the spacecraft is doing really well;" Said Nappi: "Today feels really good. We have a lot of confidence in the vehicle, and that it'll perform very well tomorrow"

A5/OFT-2: Good afternoon; Boeing's Starliner crew capsule is presumably closing in on the International Space Station for docking this evening at ~7:10pm EDT (2320 UTC), but we’ve not seen any updates today from Boeing or NASA on vehicle performance

A5/OFT-2: We're curious about the status of the 2 OMAC jets that failed off during the orbit insertion burn Thursday evening and about the overall health of the Starliner after initial checkout; but no word yet >16 hours after last night’s post-launch briefing

A5/OFT-2: We, too, have heard Starliner is on track for docking with the ISS at 7:10pm EDT (2310 UTC) as planned; but disappointing that reporters have to turn to sources to get such basic information about a high-profile mission; still no official word on general health/status

A5/OFT-2: Mission control to the ISS crew ~2:45pm EDT (1845 UTC): "Wanted to let you know the IMMT (ISS mission management team) polled go to continue with the rendezvous;" Bob Hines, aboard ISS, replied "OK, that is great news"

5/OFT-2 (1/2): Finally, a status report from Boeing; Starliner systems performing well overall; engineers studying "off-nominal” cooling loop but temps stable; OMAC thruster failures result of drop in chamber pressure; cause not addressed in update, but no risk to rest of flight

A5/OFT-2 (2/2): Boeing says the spacecraft executed all its "demo" burns as planned; guidance & nav systems working well, flight software running normally, power generation is positive and good comms through NASA's TDRS comsats

A5/OFT-2: Kjell Lindgren aboard ISS: "Houston, we have CST-100 in sight;" good video from the station showing the Starliner on its approach; now about 500 meters from the ISS

A5/OFT-2: A picture paints a thousand words: A SpaceX Crew Dragon in the foreground, docked to Harmony module's zenith port, with Boeing's Starliner in the distance approaching the lab complex on its way to docking at the space station's forward port

A5/OFT-2: Completing another test, the station crew sent commands directly to the Starliner, telling the ship to halt its approach at 250 meters; the test verified the ship will properly respond to commands from the lab if necessary

A5/OFT-2: Starliner is now executing the Demo 6 maneuver, another test of its ability to halt its approach to the station and back up slightly just outside the "keep out sphere," a protected volume around the lab complex

A5/OFT-2: Starliner is continuing to hold at about 200 meters while flight controllers work through "a couple of small issues"

A5/OFT-2: Flight controllers say they understand a discrepancy between the Starliner's actual and apparent positions as displayed by instrumentation and are resuming the spacecraft's approach to the space station; now inside 200 meters

A5/OFT-2: The Starliner will stop at 90 meters and stand by while flight controllers assess tracking data and vehicle performance

A5/OFT-2: Flight controllers now say lighting is sufficient for Starliner to bypass a 90-meter hold point and move straight in to the 10-meter point where it will briefly halt its approach while engineers assess its readiness to dock

A5/OFT-2: NASA is ruling out a docking during the first window and is now setting up for a docking attempt, from the 10 meter point, around 7:50pm EDT (2350 UTC); actual docking will be shortly thereafter

A5/OFT-2: The flight plan has always included 2 docking windows; the 1st window required a final approach initiation by ~7:11pm; the 2nd window opens around 7:55pm; meanwhile, Starliner is pressing ahead to the 10-meter hold point

A5/OFT-2: Starliner is now holding position 10 meters from the International Space Station, lined up on the Harmony module's forward port; gorgeous video

A5/OFT-2: Situational awareness, showing views seen in mission control

A5/OFT-2: NASA says the revised approach initiation time is 7:53pm EDT (1153 UTC, setting up a docking ~7:57pm); window for approach closes at 8:35pm

A5/OFT-2: NASA tells the station crew flight controllers are assessing an issue of some sort with the NASA docking system (NDS) used by Starliner and will adjust the final approach initiation time; no details on what the issue might be (hopefully minor!)

A5/OFT-2: NASA says a few NDS components did not go to an intended configuration after extension; they are retracting the mechanism for a reset, a procedure that will take about 30 minutes to complete; that would appear to move docking to very late in the 2nd window

A5/OFT-2: Assuming a good docking ring extension, NASA says the latest final approach initiation time from the 10-meter point is 8:42pm EDT (0042 UTC) with docking expected about 4 minutes later; "we do expect to make this window," CAPCOM says

A5/OFT-2: NASA tells the ISS crew they are "go" for final approach initiation; NDS docking ring is now fully extended and ready for capture

A5/OFT-2: Final approach is now underway, running about 15 minutes ahead of schedule; vehicle is now inside 10 meters and moving in...


A5/OFT-2: For the first time, NASA's post-shuttle drive for independent access to space for USOS astronauts takes shape in orbit with two commercial crew vehicles from two different vendors, SpaceX and Boeing, docked at the International Space Station

A5/OFT-2: 2 sets of hooks have driven closed to firmly lock the Starliner to the space station; hatches will be opened at 11:45am EDT (1545 UTC) Saturday; in the meantime, here's a look at the newest space station configuration (forgot to push send!)

A5/OFT-2 (1/3): Summarizing a post-docking briefing: NASA Commercial Crew Program Manager Steve Stich says low temps in the Starliner's 2 cooling loops required manual intervention, but the system was never close to violating margins for docking; loops are stable

A5/OFT-2 (2/3): Boeing VP Mark Nappi says engineers don't yet know what caused 2 OMAC thrusters in the Starliner's service module to fail earlier; several explanations have been discussed, but engineers may never know because the SM burns up during re-entry

A5/OFT-2 (3/3): All in all, Stich, Nappi and space ops chief Kathy Lueders say they're pleased with the Starliner's performance to this point; while not a trouble-free rendezvous and docking, the system worked well overall; a major milestone for Boeing

A5/OFT-2: Good morning; Kjell Lindgren Bob Hines are working through procedures to open hatches leading to the Starliner capsule docked at the forward port of the Harmony module; NASA TV coverage is underway, including a shot of Rosie the Rocketeer

A5/OFT-2: A couple of really nice shots of the Starliner's approach to the ISS last night taken by ESA astronaut Samantha Cristoforetti:

A5/OFT-2: The hatch to Starliner is now open; Kjell Lindgren and Bob Hines are now inside, working through procedures

A5/OFT-2: Cosmonaut Denis Matveev (gray shirt) has joined Kjell Lindgren and Bob Hines in the Starliner, lending a hand with post-docking procedures; the Starliner's zero-G indicator doll - Jebediah "Jeb" Kerman - of Kerbal Space Program fame, looks on with Rosie the Rocketeer

A5/OFT-2 (1/3): ISS commander Oleg Artemyev, his 2 Soyuz crewmates (dark shirts) and the station's 4 SpaceX Crew Dragon astronauts (red shirts) gathered for a brief Starliner welcome ceremony shortly after the newly arrived crew capsule's hatch was opened

A5/OFT-2 (2/3): "I have a lot of friends who work at Boeing and I know how hard, but very interesting, (it is) to make a new ship," Artemyev said in English. "Congratulations Boeing team and ground control team with this ... very important victory"

A5/OFT-2 (3/3): Astronaut Bob Hines: "Back in 2014, NASA awarded the commercial crew contracts, and this is the day they envisioned where we have 3 human-rated vehicles docked to the space station ... This is a momentous day in NASA's history, paving the way for the future"

A two-stage Chinese Long March 2C rocket launched Friday and delivered three communications test satellites into an orbit about 550 miles (880 kilometers) above Earth.

The Long March 2C rocket lifted off from the Jiuquan launch base in the Gobi Desert of northwestern China at 6:30 a.m. EDT (1030 GMT) Friday, according to the China Aerospace Science and Technology Corp., or CASC, the state-owned organization in charge the Chinese space industry.

The liquid-fueled launcher flew south from Jiuquan, then deployed a Yuanzheng 1S upper stage to finish the job of placing the three satellites into the proper orbit for deployment.

U.S. military tracking data confirmed the the satellites were deployed in a near-circular orbit at an average altitude of about 550 miles, with an inclination of 86 degrees to the equator.

Few details about the satellites were disclosed by Chinese officials, but two of the communications spacecraft were manufactured by Chang Guang Satellite Technology Co. Ltd., a commercial company that has previously specialized in building Earth-imaging satellites. The third satellite was built by the China Academy of Space Technology, a government-owned enterprise part of CASC.

“These satellites will carry out tests and verifications of in-orbit communication technologies,” China’s state-run Xinhua news agency reported.

Chinese companies are developing technologies for a large “megaconstellation” consisting of thousands of internet satellites, similar to SpaceX’s Starlink and the OneWeb broadband networks.

The Long March 2C rocket used Friday flew with 13.8-foot-diameter (4.2-meter) payload fairing, a larger than usual nose cone designed to provide more volume to accommodate more satellites on a single mission. China debuted the wider fairing design on a Long March 2C mission last August.

Odp: Starliner OFT-2 (2)
« Odpowiedź #12 dnia: Maj 17, 2022, 05:47 »
A5/OFT-2: The Starliner crew capsule's hatch was closed at 2pm EDT (1800 UTC), setting the stage for undocking and return to Earth Wednesday; cameras inside the spacecraft show a closeup of the now-closed hatch and Rosie the Rocketeer, the ship's instrumented mannequin

A5/OFT-2: For readers looking ahead, here's the latest timeline of entry events (in EDT; UTC+4):

A5/OFT-2: Starliner's undocking from the Harmony module's forward port remains on track for 2:36pm EDT (1836 UTC), kicking off a 4h 13m trip back to Earth; landing at White Sands, New Mexico,is targeted for 6:49pm (2249 UTC)

A5/OFT-2: Starliner undocking confirmed; at 2:36pm EDT (1836 UTC); the vehicle is now slowly backing away from the ISS

A5/OFT-2: Starliner, meanwhile, is continuing its back-away from the International Space Station; no issues following an on-time undocking at 2:26pm EDT

A5/OFT-2: This isn't my day; apologies for yet another typo; Starliner's on-time departure came at 2:36pm EDT (1836 UTC)

A5/OFT-2: An iconic shot of the Starliner capsule departing in the distance with a SpaceX Crew Dragon ferry ship visible in the foreground

A5/OFT-2: NASA TV's coverage of the Starliner capsule's return to Earth is now taking a 2-hour break; coverage will resume at 5:45pm EDT (2145 UTC), 20 minutes before the spacecraft executes the deorbit burn; standing by...

A5/OFT-2: NASA reports the 2 OMAC thrusters and 6 RCS jets that failed earlier in the mission were test fired after undocking today; all 6 RSS jets worked normally and were reselected; the 2 OMAC thrusters also fired, but did not perform to spec; not enabled for deorbit burn

A5/OFT-2: Deorbit ignition confirmed, at 6:05:07pm EDT; this is a planned 58-second burn designed to slow the ship by about 284mph; that will drop the far side of the orbit deep into the atmosphere, setting up a landing at White Sands, New Mexico

A5/OFT-2: Deorbit burn complete; the Starliner will now freefall for 27 minutes before re-entering the discernible atmosphere at ~6:33:25pm EDT (2233 UTC)

A5/OFT-2: The Starliner's no-longer-needed service module has been jettisoned as planned; 24 minutes to atmospheric entry; 40 minutes to landing

A5/OFT-2: ~2 minutes to atmospheric entry

A5/OFT-2: Starliner is now back in the lower atmosphere, protected by its heat shield as it rapidly decelerates and heats up

A5/OFT-2: The spacecraft is now exiting the plasma heating zone; descent data now updating again; 4 minutes to main chute deploy

A5/OFT-2: Main chute deploy confirmed

A5/OFT-2: Heat shield deployed; airbags inflated; all in all, "picture perfect"

A5/OFT-2: LANDING! At 6:49pm EDT (2249 UTC); Boeing recovery crews heading for the spacecraft momentarily

A5/OFT-2: Boeing says the Starliner touched down just 3 tenths of a mile from the planned landing site, "all in all a bullseye;" a welcome moment for Boeing given earlier problems and the work required to correct them

A5/OFT-2: Nice views of descent from NASA's Bill Ingalls and post landing, courtesy of a Boeing drone

A5/OFT-2: One more shot from Bill Ingalls, NASA's ace photographer

A5/OFT-2: Boeing says recovery crew using special sensors as part of a post-landing "sniff test" detected traces of toxic hydrazine propellant vapor; crews are standing by to give the vapor a chance to dissipate

A5/OFT-2: Another sniff test shows no more traces of hydrazine vapor; Stephen Clark at Spaceflight Now reminds us that hydrazine vapor was detected after the SpaceX Crew Dragon returned from the Demo-2 flight in May '20, but it quickly dissipated; that appears to be the case here

A5/OFT-2: Clarifying: the Demo-2 mission launched May 2020, but it landed the following August; toxic nitrogen tetroxide was detected in that case, not hydrazine; thanks to Stephen Clark for correcting me!

A5/OFT-2: The Starliner's side hatch was opened at 8:06pm EDT (0006 UTC); "First of all, really happy for this team," said Boeing VP Mark Nappi. "I'm proud of the team because they put so much effort into this;” he said the hydrazine vapor detected post landing was not unusual

A5/OFT-2: NASA and Boeing managers will discuss the Starliner's entry, descent and landing during a 9pm EDT (0100 UTC) telecon on NASA TV

A5/OFT-2: Steve Stich, manager of NASA's Commercial Crew Program, calls the Starliner mission a major success with a "picture-perfect" landing; no evidence of an actual hydrazine leak; a few relatively minor issues, but no show stoppers; “it was a great day,” he said

F9/Crew-5 (1/4): NASA and SpaceX plan to replace the heat shield composite structure intended for the Crew-5 spacecraft after the component failed an acceptance test in May due to a "manufacturing defect;" the test simulated loads experienced during splashdown, officials say

F9/Crew-5 (2/4): Another heat shield already in production will be re-assigned to the Crew-5 vehicle and undergo the same pre-flight testing; launch remains on track for September, the agency says, but whether the current 9/1 target is still viable is not yet clear

F9/Crew-5 (3/4): The NASA statement about the heat shield was released in the wake of a report about an possible leak of hypergolic propellant aboard a recent Crew Dragon and apparent heat shield degradation; NASA says that is not the case.

F9/Crew-5 (4/4): Recent Crew Dragon entries were normal, NASA said, and "the system performed as designed without dispute. There has not been a hypergol leak during the return of a crewed Dragon mission nor any contamination with the heat shield causing excessive wear"

Jim Hartz

Jim Hartz, NBC Newsman and Former ‘Today’ Co-Host, Dies at 82
By Anita Gates Published April 24, 2022 Updated April 25, 2022

He was Barbara Walters’s on-air partner for only two years, but viewers also knew him for three decades as a correspondent, anchor and TV host.

Jim Hartz, the low-key, folksy newsman who hosted the “Today” show with Barbara Walters in the mid-1970s, less than halfway through his three-decade television career, died on April 17 in Fairfax County, Va. He was 82.

The cause was chronic obstructive pulmonary disease, his wife, Alexandra Dickson Hartz, said, adding that he had chosen to be removed from the ventilator that was keeping him alive.

Mr. Hartz may have looked boyish when he started the “Today” show job, at 34, succeeding Frank McGee, who had died a few months before at 52, but he was no beginner. He had already spent a decade in New York at WNBC, covering local stories, from John V. Lindsay’s mayoralty through Robert F. Kennedy’s funeral and well into the Watergate scandal.

The news stories he covered while on “Today” included President Richard M. Nixon’s resignation, the end of the Vietnam War and the American Bicentennial. But his “Today” career wound up lasting only two years.

Both on “Today” and in other broadcast jobs, Mr. Hartz covered numerous space missions. He and the broadcast-news pioneer John Chancellor were co-announcers in 1971 during the Apollo 15 launch, which led to a three-day lunar visit by astronauts. He was co-author of “Worlds Apart: How the Distance Between Science and Journalism Threatens America’s Future” (1997), with Rick Chappell, a former astronaut.

In a 1974 interview with The Christian Science Monitor, Mr. Hartz admitted that a NASA event was so overwhelming for him that afterward he would have no memory of what he had said on the air.

Recalling the first time he saw a Saturn rocket lifting off at Cape Kennedy on an Apollo mission, he said, “I was just not prepared for that 36-story building walking right off the platform into the air.”

James Leroy Hartz was born on Feb. 3, 1940, in Tulsa, Okla., to the Rev. Marvin Dillard Hartz, an Assembly of God minister, and Helen Elvira (Potter) Hartz. He was their fifth child.

When Jim entered the University of Tulsa, his plan was to go to medical school, but it was a halfhearted ambition. “I was under a lot of pressure from one of my brothers to become a doctor,” he told The Tulsa World half a century later. Around his junior year, he said, he had to admit that he was much more interested in journalism.

His early career progress was meteoric. By the time he graduated, in 1962, he had already done internships at local television and radio stations. He was hired as a reporter for KOTV in Tulsa that year and became a host of “Sun Up,” the channel’s morning show.

He was promoted to news director in 1964 (he was 24) and hired away by NBC that same year. In New York, he became anchor of the evening newscasts on WNBC, the network’s flagship local station, and was, several sources said, the youngest correspondent ever hired by the network.

The “Today” job came along in 1974, when executives chose him to replace Mr. McGee, passing over Tom Brokaw and Tom Snyder, who were both considered more dynamic personalities and both better known nationally. But Mr. Hartz’s laid-back style seemed to be a better fit with Ms. Walters, who had been promoted to co-host after 13 years with the show and was determined, she made clear, not to take a back seat to anyone.

When she announced in the spring of 1976 that she was leaving to become ABC’s evening news co-anchor, however, NBC officials had to re-evaluate.

They hired Jane Pauley, a relatively unknown 25-year-old whose voice happened to sound much like Ms. Walters’s. Fearing that she and Mr. Hartz — two unassuming hosts — might have less than scintillating chemistry, NBC went back to Mr. Brokaw and persuaded him to take the co-host job.

But Mr. Hartz wasn’t exactly fired; it was announced that he would be given a new job, as the roving host of “Today,” reporting from across the nation. That arrangement, too, was short-lived.

From 1976 to 1979, he was news anchor at WRC, the NBC affiliate in Washington. He later worked with PBS, co-hosting “Over Easy,” a celebrity talk show, alongside the actress Mary Martin, and “Innovation,” a weekly science show. In a 1985 review of “Innovation”, John Corry, of The New York Times, called the show “vaguely, but never unintelligently, cheerful.” Much like its host.

In the early 1990s, Mr. Hartz was a host of “Asia Now,” a PBS co-production with NHK, Japan’s public broadcaster, originating from Tokyo. In 1993, he became chairman of the Will Rogers Memorial Commission, headquartered in Oklahoma. It oversees the Will Rogers Memorial in Claremore and the Will Rogers Birthplace in Oologah.

In 1960, while still in college, he married Norma Tandy, his Tulsa high school sweetheart who died in January, and they had three children. A year after their 1979 divorce, he married Alexandra Dickson, a social worker in Alexandria, Va.

She survives him, as do his two daughters, Jana Hartz Maher and Nancy Hartz Cole; six grandchildren and six great-grandchildren. His son, John Mitchell Hartz, died at 52 in 2015.

The space program remained a fascination to Mr. Hartz. At a 20th-anniversary gala for the Apollo 11 project in Houston, he described the 1969 moon landing in lofty terms, calling it “the grandest thing we could think to do” at the time and lauding “what man can do with a singleness of mind and a clearly defined goal.” But even that accomplishment could sound almost down to earth when he fell back on his folksy manner in talking about it.

“The truth is,” he said, “we went there just to check it out — friendly-like.”
