How did Apollo 13 navigate?

The Navigation report for Apollo 13 describes it this way: “The cusps of the Earth terminator were placed on the Y axis of the COAS. The illuminated part of the Earth was placed at the top of the reticle. Pitch attitude was achieved by placing the Sun in the upper portion of the AOT (see below).

How did the Apollo 13 crew fix the problem?

2 oxygen tank onboard Apollo 13 had been accidentally dropped during maintenance before the Apollo 10 mission in 1969, causing slight internal damage that didn’t show up in later inspections. The testing team decided to solve this problem by heating the tank overnight to force the liquid oxygen to burn off.

How did Apollo 13 use the lunar module?

The Apollo 13 continued on to the Moon, and the LM descent engine was used to accelerate the spacecraft around the Moon and back to Earth. The LM re-entered and burned in the Earth’s atmosphere over the southwest Pacific, any surviving pieces impacted in the deep ocean off the coast of New Zealand.

What were the main steps to save Apollo 13?

NASA makes a plan to save Apollo 13 which ends up being successful, saving the lives of the astronauts onboard. The astronauts rationed water so that there would be enough to cool Aquarius. They had to turn off almost everything in order to save power.

Where did the Apollo 13 crew safely land back on Earth?

the Pacific Ocean
Navigation was another problem, and Apollo 13’s course was repeatedly corrected with dramatic and untested maneuvers. On April 17, tragedy turned to triumph as the Apollo 13 astronauts touched down safely in the Pacific Ocean.

How did Mission Control help solve the problem in #1 on the earth?

Mission control worked hard to rescue them. When the spacecraft had too much carbon dioxide, mission control helped. Over the radio, they helped the crew build a special filter using plastic bags, cardboard and a sock. Mission control also had to help the crew stay on the right path back to Earth.

Who saved the Apollo 13 mission?

Fifty years ago this week, an explosion on the Apollo 13 moon mission stranded three astronauts hundreds of thousands of miles from home. You probably know that Fred Haise, Jim Lovell, and Jack Swigert made it home safely (water landing shown, with two of the astronauts in white).

How did duct tape save the lives of the Apollo 13 crew?

When most people think of emergency fixes in space, the first incident that comes to mind is the famous Apollo 13 mission. The astronauts fashioned duct tape and surplus materials into air filtration canisters in the lunar module to keep all three astronauts alive for the entire trip home.

How did Apollo 13 use earth’s terminator for navigation?

Graphics from the Apollo 13 report on using Earth’s terminator for navigation. The Navigation report for Apollo 13 describes it this way: “The cusps of the Earth terminator were placed on the Y axis of the COAS. The illuminated part of the Earth was placed at the top of the reticle.

What happened to Apollo 13 when they landed on Earth?

Reentry and splashdown During the morning of April 15, Apollo 13 entered the region of gravitational influence of Earth, at a distance from Earth’s surface of 348,064 km (216,277 miles). Calculations showed that the speeded-up trajectory needed an additional refinement, so the lunar module descent propulsion system was again ignited.

Who was the Apollo 13 crew member who went to the Moon?

…command module pilot on the Apollo 13 mission (April 11–17, 1970), in which an intended Moon landing was canceled because of a ruptured fuel-cell oxygen tank in the service module. The crew, consisting of Swigert, lunar module pilot Fred W. Haise, Jr., and commander James A. Lovell, Jr., returned safely…

What happened to the Apollo 13 service module?

The damaged service module drifting away from Apollo 13 after being jettisoned prior to reentry of the command module, April 17, 1970. The astronauts then moved out of the lunar module and back into Odyssey, powering up the life-support systems that had been shut down in order to conserve them for reentry.
