How much oxygen did the astronauts have on the lunar module?

How much oxygen did the astronauts have on the lunar module?

Oxygen Supply The atmosphere in the Apollo spacecraft was 100\% oxygen, at a pressure of five pounds per square inch.

Was the LEM pressurized?

In some places the walls were so thin – the vehicle was designed to fly in a vacuum so only had to withstand being pressured to 5 psi – astronauts had to watch they didn’t hit anything too hard. The foil that acted as a micrometeoroid shield in some sections was actually taped in place.

How much oxygen is in a space suit?

Spacesuits for the space shuttle era are pressurized at 4.3 pounds per square inch (psi), but because the gas in the suit is 100 percent oxygen instead of 20 percent, the person in a spacesuit actually has more oxygen to breathe than is available at an altitude of 10,000 feet or even at sea level without the spacesuit.

Is the Apollo 13 LEM still in space?

The LM was jettisoned shortly before reaching Earth, the astronauts returning to the Command Module for the reentry. 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.

How many oxygen tanks were used on Apollo 13?

Two oxygen tanks essentially identical to oxygen tank no. 2 on Apollo 13, and two hydrogen tanks of similar design, operated satisfac- torily on several unmanned Apollo flights and on the Apollo 7, 8, 9, 10, 11, and 12 manned missions.

What is the weight of the Apollo 9 PLSS?

It was tested in space for the first time by Rusty Schweickart in a stand-up EVA in Earth orbit on Apollo 9. His PLSS weighed 84 pounds (38 kg) on Earth, but only 14 lb (equivalent to the Earth weight of 6.4 kg) on the Moon. The OPS weighed 41 pounds (19 kg) on Earth (6.8 lb (equivalent to the Earth weight of 3.1 kg) on the Moon).

How much oxygen is stored in a lunar EVA battery?

Lunar surface EVA times for the first four missions (Apollo 11 through 14) were limited to 4 hours, with oxygen stored at 1,020 pounds per square inch (7.0 MPa), 3.0 pounds (1.4 kg) of lithium hydroxide, 8.5 pounds (3.9 liters) of cooling water, and a 279 watt-hour battery.

What is the capacity of the oxygen tank?

The oxygen tank is designed for a capacity of 320 pounds of super- critical oxygen at pressures ranging between 865 to 935 pounds per square inch absolute (psia). The tank is initially filled with liquid oxygen at -297″ F and operates over the range from -340° F to +80’ F.
