NASA how they use computer?

Answer 1

NASA uses computers in many different ways. NASA uses computers to calculate spacecraft trajectories, figuring out where to aim a spacecraft so it will reach a particular point or orbit in space at a particular time. NASA uses computers to track spacecraft after launch, calculating how to keep them on course with minimum fuel use. This involves a compromise between waiting as long as possible to make a correction (so the actual course is known better) and correcting as soon as possible (to use less fuel for a given correction). NASA uses computers on board the spacecraft themselves to control guidance systems, propulsion systems, experiments and everything else. NASA uses computers to analyze data sent back from space missions. NASA uses computers to keep track of the thousands of objects that orbit the earth today. NASA uses computers for every administrative purpose that any other large organization would use them for, such as budgeting, personnel, word processing, e-mail, its Web site, etc., etc. It might make more sense to ask "what does NASA not use computers for?" It would be a shorter list!
