Have you ever sat in bed at night, staring up at the thousands and thousands of stars up in the dark, black sky?

Now, people can practically live up in space, for months, even years at a time.

This quote reminds me of space missions, and how they have modified in the last 1000 years. In the 1600's a brilliant scientist named Galileo started the exploration of space.

He developed the first telescope; it used lenses to see objects in space. This luminous invention had an error though; when an object was viewed through the lenses it developed a ring. What does all this history have to do with are failed missions? Precisely everything is modified from our past failures and accomplishments.

For example; engineers and scientists working on the 2001 Mars Odyssey project began looking at ways to reduce risks to their mission immediately, after the loss of Mars Climate Orbiter and Mars Polar Lander in 1999. In addition to the independent assessments made by the project, the team has also followed recommendations made by the NASA review boards investigating the losses and a NASA "Red Team" assigned to review the project. Some precautions taken were: identified parameters critical to mission success and did an independent verification of these parameters,
