APOLLO 13
“Houston, we’ve had a problem.”-James
Lovell Jr.Is the actual
quote, not “Houston, we have a problem”, as it is more commonly known as.
The famous Apollo 13 ‘successful failure’ happened in 1970, the mission that
was intended to be the third try to
land
on the moon. The Odyssey (the
command module) and its Aquarius (the
lunar
module) launched as the spacecraft and headed for the moon, specifically the
Fra Mauro highlands. The mission was aborted when the oxygen tank
that was located in the service module exploded and left the crew,
consisting of Jim Lovell, Jack Swigert, and Fred Haise, under significant
amount of pressure.
“We’re venting
something out into the- into space.”-James Lovell Jr.
The ground controllers did not have
a fun time, either, and neither did the public as they breathlessly watched
Apollo 13 try to make its way back home.
It was critical for the survival of the crew to use the Aquarius (which was
still attached to the Odyssey) as a ‘lifeboat’ (the explosion had damaged
the spacecraft’s electrical systems, which made it impossible to keep up the
generation of power to maintain the Odyssey operational). The ground
controllers and the crew made a frantic calculation to correct their course
from the original one to the moon in order to have the spacecraft go on a
free return trajectory. This feat was accomplished by firing the Aquarius’s
descent engine twice, leading the spacecraft to accelerate (after looping
around the moon) its return to Earth.
The crew did not sleep as they undocked and jettisoned the Aquarius,
retaining it for their escape back home to Earth, and releasing the damaged
service module. The mission is named the ‘successful failure’ because the
crew did make it safely back to Earth despite all their troubles.
