Considering the enormous number of things which could turn a space mission into a fatal disaster, it is remarkable that there have been so few accidents. 1967 was a bad year; in January, the Americans lost three astronauts in a fire which occurred during tests on the ground and, in April, the Russians lost astronaut komarov landing after sixteen successful Earth orbits. The accident was due to a parachute failure. Neither of these tragedies was quite what the world had expected. It was feared that one day astronauts would be strande4d in space, alive but with no possibility of returning to Earth. This very nearly happened in 1970 during the flight of Apollo 13.
The life-support and other systems of spacecraft are interlinked. This means that if one system fails it is likely to cause other systems to fail too. Designers have tried to avoid disasters by duplicating, and in some cases triplicating, important pieces of equipment; for example , Apollo has no less than three fuel cells. Even so, a breakdown in the service module of Apollo 13 was nearly fatal. On 13 April one of the low temperature oxygen tanks in the service module suddenly broke open; the explosion probably damaged the other oxygen tank close beside it. The exact reason for the explosion may never be known.the important point to note is that the oxygen from these tanks is not only used by the crew but also feeds the fuel cells and fuel cells produce electrical power and water. So, one failure immediately caused a major power failure affecting nearly every system in the command module and produced a shortage of oxygen and water for life-support.
The safe return of the astronauts was due to their ingenuity and powers of improvisation. They managed to adapt their equipment. They were able to use it for different purposes from those for which it had been originally intended.
Intelligence and the ability to use limited resources for self-preservation have always been admired by writers of adventure book. The shipwrecked sailor who converts bits of wreckage into a raft and an explorer who makes a bow and arrow from branches and bootlaces are considered heroes because they survive by their own wits. Many people thought that the advanced technology of space flight ruled out all opportunities for makeshift repairs, but Apollo 13 proved them wrong. Luckily, at the time of the accident the lunar module was still joined to the command and service modules and the lunar module had most of the things urgently needed by the disabled modules. The spacecraft was not on a free return trajectory, one which would bring it round the moon back to Earth, and rocket power was needed to bring it into such a trajectory. With out a proper power supply, the rocket of the services module could not be fired; the rocket of the lunar module had to be used instead. Inside this module there was a supply of oxygen, water and power, and a guidance System. Though it was designed for grew of two for only about thirty hours, and intended for landing on the moon, this vehicle became the lifeboat of Apollo 13.
Life for the three crew members was difficult but bearable. A lunar module can not reenter the Earth’s atmosphere without burning up, so the crew had to return to the command module, jettison their lifeboat and the service module, and turn themselves into the right position for reentry, hoping that their heat-shield had not been damaged by the explosion of the oxygen tank. Re-entry and recovery were totally successful.
