A free-return trajectory may be the initial trajectory to allow a safe return in the event of a systems failure; this was applied in the Apollo 8, Apollo 10, and Apollo 11 lunar missions. In such a case a free return to a suitable reentry situation is more useful than returning to near the Earth, but then needing propulsion anyway to prevent ...
Flight path of the Apollo 11 human lunar landing mission, ... Such a trajectory was used for the Apollo 8, Apollo 10, Apollo 11, and Apollo 12 crewed lunar missions.
For the Apollo lunar missions, TLI was performed by the restartable J-2 engine in the S-IVB third stage of the Saturn V rocket. This particular TLI burn lasted approximately 350 seconds, providing 3.05 to 3.25 km/s (10,000 to 10,600 ft/s) of change in velocity , at which point the spacecraft was traveling at approximately 10.4 km/s (34150 ft/s ...
Apollo 11 astronaut Michael Collins returned Tuesday to the exact spot where he flew to the moon 50 years ago with Neil Armstrong and Buzz Aldrin.
The first three lunar missions (Apollo 8, Apollo 10, and Apollo 11) used a free return trajectory, keeping a flight path coplanar with the lunar orbit, which would allow a return to Earth in case the SM engine failed to make lunar orbit insertion. Landing site lighting conditions on later missions dictated a lunar orbital plane change, which ...
The Apollo 11 crew bent some of the rods intended to hold the flag out straight, which added some ripples. The Apollo 12 astronauts had the same issue. SEE MORE SPACE WEEK COVERAGE: Buzz Aldrin ...
