Space exploration
is the discovery and exploration of outer space by means of space technology.
Physical exploration of space is conducted both by human spaceflights and by robotic spacecraft.

risks of exploring space:
Space travel can beneficial to mankind, but there are dangers as well. As the
Columbia Space Tragedy has showed, accidents can, and will, happen. Injuries and
deaths have resulted from accidents that happened since man started to explore
space. These are, of course, a result of the various dangers that Space poses.
If the dangers are not taken care of properly, tragedies will occur. Here we
have listed some of the dangers and their impact on astronauts.
- DuringLaunch : A faulty O-ring on the booster rocket, carrying the Shuttle Challenger, caused
the explosion during takeoff which took the lives of 7 astronauts.
- In Space Mission: An explosion on the exterior of the Apollo 13 capsule cut short the mission to
the moon. The 3 astronauts aboard the capsule were able to use the LEM (Lunar
Excursion Module) for life support until their successful re-entry. - while training :3 astronauts died while training for the 1st Apollo mission. A fire broke out in
their training capsule. Because there was no escape hatch, by the time the
astronauts could be reached, they were dead. - Extreme Temperatures :The extreme
temperature of space is another threat. From freezing darkness to
boiling.
sunlight, the hostile environment of Space requires equipment to be
carefully and properly designed. - Space Debris :
result of human activity in Space, it is one of the greatest
dangers. Previous
missions have left behind great amount of debris. There
are an estimated 10,000
man-made objects larger that 10 cm in orbit and
probably tens of millions of
fragments less than 1 cm. the risk of
collision is high. Collision with such
debris could damage the thermal
tiles, leading to dire consequences, such as
the break-up of
shuttles.
