50 Years Ago: Apollo 10 Passes Countdown Demonstration Test
May 2, 2019

Two weeks before the Apollo 10 launch, engineers at Kennedy Space Center’s Launch Complex 39B worked to overcome a problem with the Saturn V rocket’s first stage. On April 28, 1969, a planned power outage to conduct maintenance at the Launch Control Center also caused power to be lost at the launch pad, where not all systems had backup power. The rocket’s first stage was loaded with its flight load of RP-1 fuel, and the loss of power caused the failure of pneumatic controls keeping prevalves at the bottom of the tank closed and the prevalves opened, spilling 5,280 liters of RP-1 fuel onto the launch pad’s flame trench. Since the fuel tank didn’t have any relief valves to allow air to enter the tank as fuel drained out, the loss of fluid volume caused the top of the tank to dimple inward. Quick thinking engineers at the pad instituted a work around to refill the tank and the dimple popped out with a very audible “boomp.” Launch pad manager John J. “Tip” Talone concluded of the quick action, “It worked like a champ.” Concern with any possible cracks in the fuel tank was resolved through non-destructive testing and visual inspections.

Nation: USA. Related Persons: Cernan, Cooper, Eisele, Mitchell, Stafford, Young. Agency: NASA Houston. Program: Apollo. Class: Moon. Type: Manned lunar spacecraft. Flight: Apollo 10. Spacecraft: Apollo CSM. Duration: 8.00 days. Decay Date: 1969-05-26 . USAF Sat Cat: 3941 . COSPAR: 1969-043A. Apogee: 186 km (115 mi). Perigee: 185 km (114 mi). Inclination: 32.50 deg. Period: 88.19 min.

Final dress rehearsal in lunar orbit for landing on moon. LM separated and descended to 10 km from surface of moon but did not land. Apollo 10 (AS-505) - with crew members Thomas P. Stafford, Eugene A. Cernan, and John W. Young aboard - lifted off from Pad B, Launch Complex 39, KSC, at 12:49 p.m. EDT on the first lunar orbital mission with complete spacecraft. The Saturn V's S-IVB stage and the spacecraft were inserted into an earth parking orbit of 189.9 by 184.4 kilometers while the onboard systems were checked. The S-IVB engine was then ignited at 3:19 p.m. EDT to place the spacecraft in a trajectory toward the moon. One-half hour later the CSM separated from the S-IVB, transposed, and docked with the lunar module. At 4:29 p.m. the docked spacecraft were ejected, a separation maneuver was performed, and the S-IVB was placed in a solar orbit by venting residual propellants. TV coverage of docking procedures was transmitted to the Goldstone, Calif., tracking station for worldwide, commercial viewing.

On May 19 the crew elected not to make the first of a series of midcourse maneuvers. A second preplanned midcourse correction that adjusted the trajectory to coincide with a July lunar landing trajectory was executed at 3:19 p.m. The maneuver was so accurate that preplanned third and fourth midcourse corrections were canceled. During the translunar coast, five color TV transmissions totaling 72 minutes were made of the spacecraft and the earth.

At 4:49 p.m. EDT on May 21 the spacecraft was inserted into a lunar orbit of 110.4 by 315.5 kilometers. After two revolutions of tracking and ground updates, a maneuver circularized the orbit at 109.1 by 113.9 kilometers. Astronaut Cernan then entered the LM, checked all systems, and returned to the CM for the scheduled sleep period.

On May 22 activation of the lunar module systems began at 11:49 a.m. EDT. At 2:04 p.m. the spacecraft were undocked and at 4:34 p.m. the LM was inserted into a descent orbit. One hour later the LM made a low-level pass at an altitude of 15.4 kilometers over the planned site for the first lunar landing. The test included a test of the landing radar, visual observation of lunar lighting, stereo photography of the moon, and execution of a phasing maneuver using the descent engine. The lunar module returned to dock successfully with the CSM following the eight-hour separation, and the LM crew returned to the CSM.

The LM ascent stage was jettisoned, its batteries were burned to depletion, and it was placed in a solar orbit on May 23. The crew then prepared for the return trip to earth and after 61.5 hours in lunar orbit a service propulsion system TEI burn injected the CSM into a trajectory toward the earth. During the return trip the astronauts made star-lunar landmark sightings, star-earth horizon navigation sightings, and live television transmissions.

Apollo 10 LM - . Call Sign: Snoopy. Payload: Apollo LM 4. Mass: 13,941 kg (30,734 lb). Nation: USA. Agency: NASA Houston. Program: Apollo. Class: Moon. Type: Manned lunar spacecraft. Flight: Apollo 10. Spacecraft: Apollo LM. Duration: 8.00 days. Decay Date: 1969-05-26 . USAF Sat Cat: 3941 . COSPAR: 1969-043x. Apogee: 186 km (115 mi). Perigee: 185 km (114 mi).

When Apollo 10 launched on May 18, 1969, it was the fifth launch of the Saturn V. It carried Mission Commander Thomas Stafford, command module pilot John Young and lunar module pilot Eugene Cernan to the Moon. The crew performed the first lunar orbit rendezvous, and the lunar landing mission profile was performed except for powered descent, landing and ascent of the lunar module. The mission objectives were to rehearse all the steps and reproduce all the events of the Apollo 11, the first lunar landing mission, with the exception of the lunar touchdown, stay and liftoff.

The mission transmitted the first live color television transmissions to Earth, which began three hours after launch when Apollo 10 was 3,570 miles from Earth.

Command Module, Apollo 10

Apollo 10 with Command Module 106, Charlie Brown, with was launched on May 18, 1969, atop a Saturn V rocket. The crew consisted of Commander Tom Stafford, Command Module Pilot John Young, and Lunar Module Pilot Eugene Cernan. The mission was a dress rehearsal for the Apollo 11 landing on the moon and was the first time the Lunar Module was tested in lunar orbit. Once in lunar orbit, Stafford and Cernan flew the LM "Snoopy" to within 14.5 km of the lunar surface but, instead of landing, they performed a planned simulated abort which carried them away from the moon. Apollo 10 orbited the moon 31 times before returning to Earth. "Charlie Brown" landed in the Pacific Ocean on May 26. The success of the mission was the last step before the culmination of the dream, a manned landing on the moon the following July.

Accountability for Command Module 106 was transferred to the Smithsonian Institution in April 1970 just prior to its shipment to Europe for a display tour under the auspices of the United States Information Agency. Following display in several counties (including the USSR, France and the Netherlands), in 1978 the spacecraft was place on loan to the London Science Museum, where it has remained on public display.

(...) About his time in space, Stafford said, "It changes you … As you look back, you see a little blue and white baseball, actually it’s smaller than a baseball. But it’s hard to envision that is where all the people you’ve known all your life are, where you went to school, your friends, your family.

(...) Peanuts has also teamed with Apple TV to present a 10-minute feature that includes archival interviews of two of the three Apollo 10 astronauts, Tom Stafford and Eugene Cernan, as well as an interview with current NASA flight director, Ginger Kerrick. This featurette presents a light-hearted look at Apollo 10 from the imagination of Documentarian Morgan Neville and starring Jeff Goldblum and Ron Howard, playing themselves. The short feature, Peanuts in Space: Secrets of Apollo 10, is being released on the anniversary of the Apollo 10 launch.

NASA has shared a proud association with Charles M. Schulz and his American icon Snoopy since Apollo missions began in the 1960s. Schulz created comic strips depicting Snoopy on the Moon, capturing public excitement about America’s achievements in space. In May 1969, Apollo 10 astronauts traveled to the Moon for a final checkout before lunar landings on later missions. Because the mission required the lunar module to skim the Moon’s surface to within 50,000 feet and “snoop around” scouting the Apollo 11 landing site, the crew named the lunar module Snoopy. The command module was named Charlie Brown, Snoopy’s loyal owner. (...)

Apollo 10 – 50 lat temu
BY KRZYSZTOF KANAWKA ON 24 MAJA 2019


Logo misji Apollo 10 / Credits - NASA

Mija właśnie 50 lat od misji Apollo 10 – “ostatniego testu” przed historycznym lądowaniem człowieka na Srebrnym Globie.

Celem misji Apollo 10 było przetestowanie lądownika księżycowego oraz procedur lądowania na Srebrnym Globie. Misja Apollo 10 odbywała się w dniach 18 – 26 maja 1969, z czego w dniach 21 – 24 maja 1969 statek Apollo oraz lądownik LM przebywał na orbicie Księżyca. Misja zakończyła się sukcesem i otworzyła drogę do załogowego lądowania, które nastąpiło w lipcu 1969 roku.


Jedno ze zdjęć Księżyca wykonane podczas misji Apollo 10 / Credits – NASA

Ponadto, oprócz testów lądownika księżycowego, w trakcie misji Apollo 10 wykonano setki zdjęć Srebrnego Globu. Te zdjęcia posłużyły do dokładnego planowania kolejnych misji programu Apollo, w szczególności etapu lądowania na Księżycu. Dzięki temu udało się m.in. ograniczyć wielkość elipsy lądowania dla misji Apollo 11.

Misja Apollo 10 wykonała w około 70% zakładane cele fotograficzne na tę wyprawę. Udało się m.in. uzyskać dużą ilość fotografii drugiej strony Księżyca, w tym obszarów, które dotychczas były niewystarczająco dobrze sfotografowane.


Pięćdziesiąta rocznica misji Apollo 10 / Credits – NASA

W trakcie tej misji lądownik LM zbliżył się do powierzchni Księżyca na minimalną odległość 15,6 km. Nie wszystko jednak przebiegło w tej misji planowo – przykładowo doszło do nieoczekiwanego obrotu części powrotnej lądownika LM po separacji członów. Późniejsza analiza wykazała, że było bardzo blisko do utraty kontroli nad tym segmentem lądownika, co w konsekwencji doprowadziłoby do uderzenia w powierzchnię Księżyca i śmierci dwóch astronautów.

Z załogi misji Apollo 10 żyje dziś tylko Thomas Stafford – dowódca misji. John Young zmarł w 2018 roku, zaś Eugene Cernan odszedł w 2017 roku.
