How did the lunar module reattach?

How did the lunar module reattach?

At launch, the lunar module sat directly beneath the command and service module (CSM) with legs folded, inside the Spacecraft-to-LM adapter (SLA) attached to the S-IVB third stage of the Saturn V rocket.

How did Apollo 11 get back to Earth with no fuel?

The TLI placed Apollo on a “free-return trajectory” – often illustrated as a figure of eight shape. This course would have harnessed the power of the Moon’s gravity to propel the spacecraft back to Earth without the need for more rocket fuel.

How did the command module connect to the service module?

The command module was mated atop the service module, connected by three tension ties extending from the CM’s heat shield to six compression pads on the top of the SM. These ties were stainless straps 2.5 inches wide and 4 inches long bolted to the spacecraft on either end.

Why did the lunar module have to turn around?

Because the LM was designed to land on the moon and return two men to orbit with minimal. It was well equipped for that mission, but in no way suited to passing through earth’s atmosphere at hypersonic speeds.

Is the lunar module still in orbit?

Apollo 9 was an Earth orbital mission so its lunar module burned up in the Earth’s atmosphere. Apollo 10 jettisoned its lunar module Snoopy into solar orbit where it remains today. They are, of course, still up there along with the remains of the smashed S-IVB and lunar modules for future archaeologists to explore.

Why was the lunar module covered in foil?

It is. The foil was there to reflect sunlight and prevent overheating of fuel tanks, valves and pipes and electronic circuitry. The direct unfiltered sunlight will cause metal to heat to very high temperatures, even if painted white.

Did Apollo 13 explode?

The Apollo 13 malfunction was caused by an explosion and rupture of oxygen tank no. 2 in the service module. The explosion ruptured a line or damaged a valve in the no. 1 oxygen tank, causing it to lose oxygen rapidly.

How did the Apollo 11 get back to Earth?

Ascent From the Moon At 1:53 pm on July 21 the astronauts lifted off from the Moon in the module’s ascent stage and then rendezvoused with Collins and the orbiting spacecraft. The three explorers fired away from lunar orbit on July 22 and returned to Earth on July 24.

What happened to the service module?

An entire panel on the SM was blown away by the explosion of an oxygen tank. The damaged service module drifting away from Apollo 13 after being jettisoned prior to reentry of the command module, April 17, 1970.

How many crew members could the command module hold?

The CSM functioned as a mother ship, which carried a crew of three astronauts and the second Apollo spacecraft, the Apollo Lunar Module, to lunar orbit, and brought the astronauts back to Earth….Apollo command and service module.

Payload capacity 2,320 lb (1,050 kg)
Crew capacity 3
Volume 218 cu ft (6.2 m3)

How does the lunar module Return to Earth?

Once in lunar orbit, the ascent stage meets up with the CSM ( discussed a bit here ), and docks again, and the crew return to the Command Module. The LM ascent stage is discarded, and the CSM fires the big engine again to return to Earth.

When did the Lunar Module dock with the command module?

1969: Lunar Module docked with the Command Module – YouTube Human Space Flight (HSF) – Apollo History”The surface exploration was concluded in 2½ hours, when the crew re-entered the lunar module.”…

How did the Apollo 11 lander module work?

NASA’s Apollo 11: How the Lander Module worked. The Lander, also known as the Lunar Module (LM), was a two-stage craft built to separate from the Apollo Command and Service Module, and then travel to and from the moon’s surface. It first landed on the moon on 20 July 1969. Generally the descent stage was left on the moon,…

What was the name of the Lunar Module on Apollo 11?
