Which Apollo blew up on the ground?
Apollo 13
The Apollo 13 malfunction was caused by an explosion and rupture of oxygen tank no. 2 in the service module.
How did Apollo 11 leave Earth?
The astronauts used Eagle’s ascent stage to lift off from the lunar surface and rejoin Collins in the command module. They jettisoned Eagle before they performed the maneuvers that propelled Columbia out of the last of its 30 lunar orbits onto a trajectory back to Earth.
How long did Apollo 13 lose communicate with Earth?
1.8 seconds
Communications and telemetry to Earth were lost for 1.8 seconds, until the system automatically corrected by switching the high-gain S-band antenna, used for translunar communications, from narrow-beam to wide-beam mode. The accident happened at 55:54:53 (03:08 UTC on April 14, 10:08 PM EST, April 13).
How did Apollo 13 survive reentry?
The oxygen was not just for the astronauts to breathe, but also fed the fuel cells that powered the spacecraft. The command module was dying, quickly. But the lunar lander, docked to the command module, was intact. Eighty-seven hours after the explosion, the Apollo 13 astronauts safely splashed in the Pacific Ocean.
Where was the command module during the trans-Earth injection burn?
At the time of the Trans-Earth Injection burn we expect that the Command Module will be about 1 mile below the LM and about 20 miles in front of it. Being in a higher orbit, the LM’s velocity around the Moon is slower and so the CSM is getting ahead of it. 133:49:44 Duke: Hello, Apollo 11.
How did Apollo 11 get back to Earth?
When behind the Moon, Apollo 11 fires the large engine on the Service Module to accelerate out of lunar orbit and enter its homeward-bound trajectory towards Earth. The crew photograph the receding Moon, and receive a call from the Head of the Astronaut Office, Deke Slayton.
How long was the burn on Apollo 11?
This is Apollo Control. The Flight Dynamics Officer reports that the burn was very nominal; almost precisely as planned. The burn duration was about 3 seconds long, but the velocity change was almost precisely what we had been expecting. At the present time, Apollo 11 is 1,076 nautical miles [1,993 km] from the Moon.
