Apollo 13 (April 11–17, 1970) was the seventh crewed mission in the Apollo space program and would have been the third Moon landing.The craft was launched from Kennedy Space Center on April 11, 1970, but the landing was aborted after an oxygen tank in the service module (SM) exploded two days into the mission, disabling its electrical and life-support system.
Chabot Observatory calendar records an application of optical tracking during the final phases of Apollo 13, on April 17, 1970: Rachel, Chabot Observatory's 20-inch refracting telescope, helps bring Apollo 13 and its crew home. One last burn of the lunar lander engines was needed before the crippled spacecraft's re-entry into the Earth's ...
Charged with those logistics support functions that address on-orbit maintenance, support data and documentation, logistics information systems, maintenance data collection and maintenance analysis. The OSO is also responsible for mechanical systems—such as those used to attach new modules or truss sections to the vehicle during assembly.
A new documentary chronicling the events surrounding the Apollo 13 mission, in which three astronauts found themselves stranded in space following a catastrophic explosion, is being released on ...
Apollo 13 was slated to be the third landing on the moon after Apollo 8 (1968) and Apollo 12 (1969). Launched on April 11, 1970, the crew was led by commander Lovell, along with command module ...
The tracking data improved the analysis of the impact recorded by the seismometers left by earlier Apollo crews. The S-IVB used the same frequency pair as the LM. Normally the LM was inactive during flight, however, this was a problem when during the Apollo 13 flight as the LM had to be powered up early to be used as a life boat. [5]
Astronauts manually flew Project Gemini with control sticks, but computers flew most of Project Apollo except briefly during lunar landings. [6] Each Moon flight carried two AGCs, one each in the command module and the Apollo Lunar Module, with the exception of Apollo 7 which was an Earth orbit mission and Apollo 8 which did not need a lunar module for its lunar orbit mission.
As another active seismic experiment, the S-IVBs on Apollo 13 and subsequent missions were deliberately crashed on the Moon instead of being sent to solar orbit. [76] Starting with Apollo 13, descent orbit insertion was to be performed using the service module engine instead of the LM engine, in order to allow a greater fuel reserve for landing.
