	Apollo
		Apollo X was the designation given at various times during the Apollo program for follow-on versions of the spacecraft for extended earth-orbit operations (for a time, all follow-on projects using Apollo hardware were termed 'Apollo X'.
		Apollo X also covered rather extensive work to give Apollo a land landing capability, using a parawing or retrorockets, so that the vast naval recovery fleet could be dispensed with.
		The Apollo Lunar Roving Vehicle was one of those sweet pieces of hardware that NASA and its contractors seemed to be able to develop so effortlessly during the short maturity of the Apollo programme.

	Talk:Saturn V - Wikipedia, the free encyclopedia
		The next mission [Apollo 6] was one that was really a solid test of the Saturn launch vehicle where we lost two engines on one side during powered flight during launch, and the Saturn's not supposed to fly.
		According to Apollo by the Numbers, on average the mass of the spacecraft for a lunar mission was 110,000kg plus the instrument unit of about 4500 kg we have a total weight of 114500 kg.
		Of course for the Apollo flights we have to remember that the rocket also launched the S-IVB into orbit with fuel on board for the TLI burn.

		In the event of an abort requiring the destruction of the rocket, the range safety officer would send the signal for shaped explosive charges attached to the outer surfaces of the rocket to detonate.
		During two launches, Apollo 6 and Apollo 13, the Saturn V was even able to recover from the loss of engines.
		See Apollo abort modes for more information about the various abort modes that could have been used during a launch.

	AGC - Miscellaneous Apollo Memos
		The APOLLO Guidance Computer was designed to provide the computation necessary for guidance, navigation and control of the Command Module and the Lunar Landing Module of the APOLLO spacecraft.
		The successful recovery of the Apollo 13 flight is shown to have been the direct result of the performance of the flightcrew and the application of the talents of many different organizations focused on the mission support task through the Mission Control Center.
		The three different accident/abort modes considered are the following: i) a constant-rate angular pitching motion of the vehicle; ii) a constant-acceleration angular pitching motion of the vehicle; iii) the rocket engine breaks away from the rest of the vehicle with a finite relative (dispersion) velocity.

	Report on Top-Level Assessment of Use of Apollo Systems for ISS CRV (part 1) \| SpaceRef - Your Space Reference
		The Apollo systems were thoroughly analyzed, validated, developed, tested, qualified, and used operationally in earth orbit, in expeditions to the moon, and in entry at speeds 50% greater than that from low earth orbit.
		Although several prior studies have examined concepts based on the use of Apollo components, it is recommended that this new study should be in sufficient depth to permit it to be traced with other approaches being considered by NASA to the same set of current OSP requirements.
		The original Apollo CM size of approximately 11.5 ft high with a base diameter of 12.8 ft. originally accommodated 3 crew members and was configured for the lunar missions.

	Apollo Launch Escape
		As Henry indicated, the SM's SPS was used for aborts after LES jettison.
		There were 4 "modes" of abort, which depended on down range distance and speed: 1 - Used the LES and was "short down-range".
		There were 4 "modes" of abort, which depended on down range > distance and speed: > 1 - Used the LES and was "short down-range".

	Apollo
		The C-2 would be essential, the study reported, for Apollo manned circumlunar missions, lunar unmanned exploration, Mars and Venus orbiters and capsule landers, probes to other planets and out-of- ecliptic, and for orbital starting of nuclear upper stages.
		Agreement was reached on tentative Saturn vehicle assignments on abort study and lunar entry simulation; on the use of the Saturn guidance system; and on future preparations of tentative flight plans for Saturns SA-6, 8, 9, and 10.
		Progress of the three Apollo feasibility study contracts was reviewed and the proposed MIT Lincoln Laboratory study on a systems concept for the ground instrumentation and tracking required for the Apollo mission was discussed.

	Apollo CSM
		Apollo spacecraft 009, first of the type that would carry three astronauts to the moon and back, was accepted by NASA during informal ceremonies at North American.
		Apollo Program Director Samuel C. Phillips notified the three manned space flight Centers that they were requested to plan for a dual AS-207/208 mission, assuming that launch would occur one month later than the 207 launch now scheduled.
		A parachute test (Apollo Drop Test 84-1) failed at EI Centro, Calif. The parachute test vehicle (PTV) was dropped from a C-133A aircraft at an altitude of 9,144 meters to test a new 5-meter drogue chute and to investigate late deployment of one of the three main chutes.

	Space Shuttle program
		NASA had conducted a series of paper-projects throughout the 1960s on the topic of reusable spacecrafts to replace their expedient "one-off" systems like Mercury, Gemini, and Apollo.
		With the major Apollo development effort winding down in the second half of the 1960s, NASA started looking to the future of the space program.
		Furthermore, because there are cases where there are no abort modes, no potential way to prevent failure from becoming critical, many pieces of hardware simply must function perfectly and so must be carefully inspected before each flight.

		An interesting detail is, taht if a LES abort would have happened, then the separation of the LES and the CM later would also take away the whole docking assembly on top of the CM with it.
		This is from the Apollo 8 Flight Journal, a formidably large document which covers all the conversations between Houston and the astronauts on Apollo 8.
		The crew demanded that the abort procedures be implemented but ground control could not see the launch vehicle gyrations in their telemetry.

		After their ignition abort modes apply to the phase where they have burnt out and been disconnected.
		Abort to Orbit (ATO) - happened on STS-51-F mission; required mission replanning, but the mission was declared a success anyway.
		Furthermore, because there are cases where there are no abort modes - no potential way to prevent failure from becoming critical - many pieces of hardware simply must function perfectly and so must be carefully inspected before each flight.

	Buran
		The success of Apollo and the failure of the N1-L3 program pointed to serious deficiencies in the technology base of the Soviet Union.
		This was tested in all thermal regimes, including abort, vacuum of down to 1.33 x 10^-3 torr.
		Abort facilities - Buran had several abort modes: lose one booster, abort once around; lose two boosters, abort return to site.
