The White House Covid response coordinator Ashish Jha appeared to undercut the Biden administration’s efforts to reinstate the federal mask mandate on Sunday, stating that the spreading BA.2 variant in the US was unlikely to have much effect on the nation’s pandemic recovery.

The justice department announced last week it would appeal the decision of a federal judge in Florida to prematurely lift the mandate on air, rail and bus travel in the US, based on the assertion by the Centers for Disease Control and Prevention (CDC) that “an order requiring masking in the indoor transportation corridor remains necessary for the public health”.

Beijingers were flooding supermarkets to stock up on food on Monday, hoping to avoid Shanghai-style shortages in the case of a city-wide lockdown as the capital records a growing number of Covid infections.

Authorities in Beijing have ordered 3.5 million residents and workers in the biggest district of Chaoyang to report for three coronavirus tests this week, after the area recorded 26 of Beijing’s 47 symptomatic cases since Friday.

On Monday, China reported 3,266 symptomatic cases and 20,454 asymptomatic cases. The majority were in Shanghai, where 19,455 were reported. Beijing reported 19 cases on Monday, including 14 symptomatic.

“The current outbreak in Beijing is spreading stealthily from sources that remained unknown yet and is developing rapidly,” a municipality official said on Sunday. (...)

Optimism among UK manufacturers has fallen at its sharpest pace since the first coronavirus pandemic lockdown two years ago as firms struggle to cope with the fastest increase in their costs since 1975, according to the latest industry health check.

With the war in Ukraine giving a fresh upward twist to the pressures on companies, the April industrial trends survey from the employers’ organisation the CBI found firms cutting back on investment and planning to pass on higher costs to consumers. (...)

Beijing has closed schools and suspended weddings and funerals in the city of 22 million in a whirlwind effort to avoid plunging China’s capital into a Shanghai-style Covid lockdown.

Fears that Beijing could soon be in lockdown have already prompted widespread stockpiling, leading to shortages in some supermarkets.

The city’s Education Bureau ordered all city schools to end classes from Friday and said it had not determined when they would be able to resume.

Beijing has moved faster than other places in China to impose restrictions while case numbers remain low. Authorities announced only 50 new cases on Thursday, bringing the total in the latest wave of infections to about 150.

The government is desperate to avoid sweeping measures imposed on Shanghai over the past month, which have caused frustration about shortages of food and basic supplies. Across China, authorities have said they are cracking down on price gouging. (...)

39) Anthony Fauci says the US is not in a ‘pandemic phase’. What does that mean?

With funds for anti-virals and other measure dwindling, some experts are concerned the US is too sanguine about future surges

The US has left the “pandemic phase” at least for now, chief medical adviser Anthony Fauci said this week, at the same time that the White House presses for urgently needed Covid-19 funding. But as cases continue mounting around the globe, the pandemic shows no signs of ending yet – and conflicting pictures offered by top health officials may hamper the renewal of critical Covid funds and efforts like vaccination campaigns.

In an interview on Tuesday, Fauci painted an optimistic, if mixed, picture. “We are certainly, right now in this country, out of the pandemic phase,” he said, before adding, “Pandemic means a widespread, throughout the world, infection that spreads rapidly among people.”

Such a definition still applies to the Covid pandemic, experts say. While confirmed cases in the US are lower than during the first Omicron wave, they are rising in nearly all American states, and the virus continues spreading around the world. (...)

40) ‘The loss is omnipresent’: the grieving daughter fighting for a US Covid memorial day

The founder of Marked by Covid believes the US has failed to properly memorialize the enormous losses

For Kristin Urquiza, there are two dimensions: before Covid, and with it. It’s as if the arrow of time veered off into an entirely new direction, to a world where nearly one million of our loved ones have vanished and millions more are struggling with the long-term effects of a mysterious illness.

“It feels like my father disappeared,” Urquiza said. Her father died on 30 June 2020, at the age of 65, in an Arizona hospital with only an ICU nurse holding his hand. “That shadow, or that loss, is omnipresent.”

And compounding the wrenching grief: many Americans, especially political leaders, don’t want to talk or even think about it, she said. They want to push the pandemic as far behind them as possible, even as people continue dying from Covid every day. (...)

North Korea has declared a “severe national emergency” after confirming its first outbreak of Covid-19, prompting its leader, Kim Jong-un, to vow to quickly eliminate the virus.

State media reported on Thursday that a sub-variant of the highly transmissible Omicron virus, known as BA.2, had been detected in the capital, Pyongyang.

“There has been the biggest emergency incident in the country, with a hole in our emergency quarantine front, that has been kept safely over the past two years and three months since February 2020,” the official KCNA news agency said.

The report said people in Pyongyang had contracted the Omicron variant, without providing details on case numbers or possible sources of infection.

North Korea had claimed it had not recorded a single case of Covid-19 since it closed its borders at the start of the pandemic more than two years ago. (...)

North Korea has announced its first Covid-19 death amid an “explosive” outbreak of fever, state media said on Friday, one day after the regime admitted for the first time that it was tackling a coronavirus outbreak.

The official KCNA news agency said six people had died, adding that one of them had tested positive for the highly transmissible Omicron variant. (...)

North Korea said on Sunday a total of 42 people had died as the country began its fourth day under a nationwide lockdown aimed at stopping the impoverished country’s first confirmed Covid-19 outbreak.

At least 296,180 more people came down with fever symptoms, and 15 more had died as of Sunday, the outlet said.

North Korea’s admission on Thursday that it is battling an “explosive” Covid-19 outbreak has raised concerns that the virus could devastate a country with an under-resourced health system, limited testing capabilities and no vaccine programme.

More than one million people have died in the Covid-19 pandemic in the US, according to Johns Hopkins, far and away the most deaths of any country.

While the sheer number of deaths from the coronavirus sets the US apart, the country’s large population of 332.5 million people does not explain the staggering mortality rate, which is among the highest in the world.

For every 100,000 residents, 291 people have died from Covid-19, according to the Johns Hopkins University Coronavirus Resource Center. Among the 20 worst affected nations, only two other countries – Brazil and Poland – have higher mortality rates per 100,000 people. (...)

North Korea stands on the brink of a Covid-19 catastrophe unless swift action is taken to provide vaccines and drug treatments, experts have said, as the number of people reported to have fallen ill rose to almost 1.5 million.

The isolated country reported another big rise in new cases of what it continues to refer to as “fever” on Tuesday, days after it admitted it had identified Covid-19 infections for the first time since the start of the global pandemic.

It recorded 269,510 additional cases and six more deaths, bringing the total number killed to 56 since late last month. About 1.48 million people have become ill with the virus since the first case was reported last Thursday and at least 663,910 people were in quarantine, according to official figures. The outbreak is almost certainly greater than the official tally, given a lack of tests and resources to monitor and treat the sick.

Aged care providers have reported more than 350 Covid deaths since the election campaign began and continue to grapple with at least 60 deaths a week, government data shows.

An analysis of government data, conducted by the United Workers Union and confirmed by the Guardian, shows that Covid deaths in aged care facilities are now occurring at rates unseen in the first two years of the pandemic.

Aged care workers are preparing to strike across the country again on Friday, furious at low pay, torrid conditions, and a lack of recognition of the huge workload and workforce pressures caused by Covid.

The latest government report shows 1,418 Covid deaths have been reported by aged care providers so far in 2022, accounting for about one in four of all Covid deaths in Australia. That dwarfs the 686 deaths in aged care in 2020 and 231 deaths in 2021. (...)

The White House resumed its coronavirus briefings on Wednesday after a six-week hiatus as Covid-19 cases rose across the nation, with the new head of Covid response calling on Congress for additional funding to pay for vaccines and treatments.

“I want to make sure we have enough resources so that we can buy enough vaccines for every American. I think that is absolutely critical. We do not have the resources to do that right now,” said Ashish Jha, the White House’s new coronavirus response coordinator, who replaced Jeff Zients in March. “So without additional funding from Congress, we will not be able to buy enough vaccines for every American who wants one.”

The last White House coronavirus briefing was held on 5 April. Since then, various mask mandates have been lifted across the country, including those on planes, trains and in automobiles.

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
by Andrew Jones — April 29, 2022

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. (...)

TAIYUAN, May 5 (Xinhua) -- China on Thursday launched a Long March-2D rocket to place a group of eight satellites in space.

Satellite Jilin-1 Kuanfu 01C, together with seven Jilin-1 Gaofen 03D satellites, was lifted at 10:38 a.m. (Beijing Time) from the Taiyuan Satellite Launch Center in the northern province of Shanxi and soon entered the preset orbit.

With its wide coverage, Jilin-1 Kuanfu 01C can provide images with a width of more than 150 km, a panchromatic resolution of 0.5 meters and a multi-spectral resolution of 2 meters. The satellite also boasts super-large storage and high-speed data transmission.

It will be used to provide commercial remote sensing data services for sectors such as land resource, mineral exploration and smart city construction.

Developed by Chang Guang Satellite Technology Co., Ltd., the eight new satellites will work with 46 previously launched satellites of the Jilin-1 family to form a constellation, providing remote sensing data and services in fields like agriculture, forestry and environmental protection.

This was the 419th flight mission of the Long March rocket series. ■

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. ■


China sets world record in long-distance quantum states transmission
 02022-05-07 17:09:56CGTNEditor : Zhao Li

Chinese scientists made record-breaking progress in realizing quantum states transmission between two ground stations over 1,200 kilometers apart via a quantum scientific experiment satellite, signalling a giant step towards constructing a global quantum information processing and communication network.

The experiment was led by Pan Jianwei, physics professor from the University of Science and Technology of China, and the related paper co-authored by Pan and his team members was then published in the international journal of Physical Review Letters on April 26.

Long-distance quantum states transmission

The long-distance quantum states transmission (QST), usually being realized by quantum teleportation, is one of the major approaches for building quantum communication networks and an essential requirement for realizing multiple quantum information processing tasks.

Assisted by long-distance quantum entanglement distribution, quantum states can be measured and then restructured to achieve long-distance transmission, with the transmission distance theoretically being infinite.

As the distance and quality of quantum entanglement distribution are affected by channel loss, decoherence and other factors, how to break the transmission distance limit has always been one of scientists' biggest concerns.

Using satellite-carried entanglement sources to distribute entanglement to two remote places and then preparing and restructuring quantum states is one of the most feasible ways to achieve long-distance quantum states transmission.

Nevertheless, due to the atmospheric turbulence, it is very hard to measure the quantum states based on quantum interference after photons propagate in the atmospheric channel.

In previous experiments, as producers of quantum states transmission were all owners of quantum entanglement sources, it was impossible to use entanglement provided by a third party to realize prior distribution and follow-up transmission of quantum states in a real sense.

China launches world's first quantum satellite

China launched the world's first quantum satellite known as the Quantum Experiments at Space Scale (QUESS), nicknamed "Micius" after an ancient Chinese philosopher, on August 16, 2016. Not until then, did the research team first realize entanglement and distribution between two different stations more than 1,000 kilometers apart with the Micius platform providing valuable entanglement distribution resources for quantum communication experiments.

In efforts to overcome quantum light interference following long-distance turbulent atmospheric transmission, the experimental team developed an optical interferometer with ultra-high stability, by optical integration bonding technology which can remain stable for a long period of time without active loop closure.

The technological breakthrough combines the quantum teleportation scheme based on two-photon path-polarization mixed entangled state. The long distance quantum states transmission between the Lijiang station in southwest China's Yunnan Province and the Delingha ground station in northwest China's Qinghai Province, which are 1,200 kilometers apart, was finally verified.

In this successful experiment, a total of six typical quantum states were verified, and the transmission fidelity surpassed the classical limit.

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.  (...)

NASA Astronaut Mark Vande Hei On How Ukraine Crisis Impacted Partnership With Russians

How an ex-Blue Origin intern got a $500,000 check from Mark Cuban to build a major SpaceX rival
Published Sat, May 7 2022 9:00 AM EDTUpdated Sat, May 7 20229:00 AM EDT [cnbc]

Seven years ago, Tim Ellis sent Mark Cuban a life-changing cold email.

Ellis was an engineer at Jeff Bezos’ space startup, Blue Origin, and he dreamed of launching his own rival company. His cold email to Cuban was an investment pitch that called space “sexy” and teased the idea of 3D printing an entire rocket.

The pitch worked – almost immediately. “A few minutes after cold emailing Mark Cuban, we had a half a million dollar commitment,” Ellis, 31, tells CNBC Make It.

Today, Ellis is the co-founder and CEO of Los Angeles-based Relativity Space, which is months away from launching the world’s first 3D-printed rocket into space. Along the way, Ellis and his co-founder Jordan Noone – who interned with Ellis at Blue Origin before landing an engineering job at SpaceX – have raised more than $1.3 billion from investors like BlackRock and Tiger Global.

That money has given Relativity Space a valuation of $4.2 billion, while funding its mission of 3D-printing rockets to compete in a private aerospace industry expected to be worth well over $1 trillion by the end of the decade.

Ellis’ penchant for rockets started early: After studying at the University of Southern California’s Rocket Propulsion Lab and landing summer internships at Blue Origin for three consecutive years, Ellis landed a full-time engineering job at Bezos’ company.

At Blue Origin, Ellis 3D-printed individual rocket parts, and became fascinated by the idea of using mega-sized 3D printers to create entire rockets. It could reduce costs, he reasoned, and potentially even pave the way for the sort of multiplanetary society that SpaceX CEO Elon Musk has often discussed.

“I realized, for that future to exist, someone was going to have to found a company somewhere that built an industrial base on Mars,” says Ellis. “You need a small, lightweight factory that you can launch on a rocket to another planet that can build a wide range of products with very little human involvement.”

Ellis figured that someone might as well be him. He and Noone say they’ve built the world’s largest metal 3D printer, the 24-foot-tall Stargate — and used it to build their first 3D-printed rocket, called the Terran 1. Last month, Ellis told Florida Today that the Terran 1 is on track to launch from the Cape Canaveral Space Force Station for its first space flight later this year.

“I’m now realizing a lot of the things that I got made fun of for [while] growing up – whether it was researching every topic under the sun, and following all of these threads, and being hyper-curious, and pattern-matching information – all of those skills have let me scale and run Relativity,” Ellis says.

To learn how Ellis built Relativity Space into a $4.2 billion company competing with the likes of Jeff Bezos and Elon Musk, watch the video above.

Starliner OFT-2
« 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"
