The ascent propulsion system (APS) or lunar module ascent engine (LMAE) is a fixed-thrust hypergolic rocket engine developed by Bell Aerosystems for use in the Apollo Lunar Module ascent stage. It used Aerozine 50 fuel, and N 2 O 4 oxidizer.
In 1973, the year after the Apollo lunar program ended, three Apollo CSM/Saturn IBs ferried crews to the Skylab space station. In 1975, one last Apollo/Saturn IB launched the Apollo portion of the joint US-USSR Apollo–Soyuz Test Project (ASTP). A backup Apollo CSM/Saturn IB was assembled and made ready for a Skylab rescue mission, but never ...
In early planning for the Apollo program, it had been assumed that two Saturn V launch vehicles would be used for each lunar mission: one for sending the crew aboard a Lunar Surface Module (LSM) to lunar orbit, landing, and returning, and a second for sending an LSM-Truck (LSM-T) with all of the equipment, supplies, and transport vehicle for ...
The PSEP was placed 16.8 meters (55 ft) from the Apollo 11 Lunar Module at Tranquility Base on July 21, 1969. [1] A set of 15 different commands could be sent to the experiment package from mission control on Earth to direct the instrument's levelling and calibration motors. [1]
The Apollo 17 lunar lander module left behind by US astronauts on the moon’s surface could be causing moonquakes, ... DOJ proposing to buy Google Chrome for $20 billion if judge OKs sale: Reports.
