by the U.S government? Remember the “Space Race” against Russia? What would have happened if we had shut down NASA before that? Getting a man to the moon was a Cold War victory! Shutting down funding for space exploration would be utterly devastating. Did you know that we can do research in space that we can’t do on earth? In space‚ we can understand more about gravity‚ and how machines work in different conditions‚ special medical research can be done in space‚ and there are many ways NASA improves

Control or "Houston" had to come up with a flawless plan to get the U.S spacemen back to the Earth. How is free-fall associated in the re-entry of a spacecraft? Free-fall is arguably the most important aspect of space travel. The free-fall law is put into action during the re-entry of the space craft to Earth. When the spacecraft enters Earth’s gravity‚ it enters the Earth at an angle. Once they get close enough‚ they start feeling terminal velocity. After falling at 9/8 m/s^2‚ they reach such a fast

Dr. Laurel Clark‚ who was lost aboard the space shuttle Columbia on February 1‚ 2003 said‚ “to me‚ there’s a lot of different things that we do during life that could potentially harm us‚ and I choose not to stop doing these things.” In all of human endeavor there are challenges and difficulties. How people respond to those challenges varies. Some run or try to hide from difficulties‚ and others rise to meet the challenge and in doing‚ reveal their true selves.
