Everything changed though in 1957‚ when the Soviet Union successfully launched the satellite Sputnik into orbit. This started the space race. In America the response to Sputnik was the creation of the National Aeronautics and Space Administration (NASA) the following year‚ with plans to send rockets and eventually men into space.

Space is for NASA not for Google! Private companies are trying their luck at space travel. One day you could possibly go up into space on a shuttle made by the same brand that makes your cellphone. There are lots of flaws to space privatization including it being unsafe‚ not going to work out long term‚ and the fact that America already has a space program. There have been several failed attempts at space travel by private companies before‚ and most of them looked promising. And most private companies

it is not worth losing the lives astronauts lives. Even though there are people willing to go to space they can lose their lives while leaving the atmosphere. An example is the 1986 challenger tragedy. There was also another space shuttle tragedy in 2003 the space shuttle Columbia exploded just a few after lift off killing all of the crew members. Another reason why space exploration is not worth the cost is because of how much it costs

seconds? After an impact involving a non-functioning satellite‚ a paint chip leaves the surface of the satellite at a speed of 96 m/s. After 17 seconds‚ how far has the chip landed? The space shuttle Endeavor is launched to altitude of 500 km above the surface of the earth. The shuttle travels at an average rate of 700 m/s. How long will it take for Endeavor to reach its orbit? How long will your trip take (in hours) if you travel 350 km at an average speed of 80 km/hr?

I vividly remember the day of the Challenger Disaster. I was five years old and in kindergarten. My teacher‚ Ms. Epton‚ brought us outside to watch the shuttle launch; something many kids have to watch on television‚ but those of us living on the coast got to witness firsthand. I remember seeing the fiery glow of the shuttle‚ the gasps by the adults‚ and quickly being hurried back into the classroom. Not much was said about what had happened‚ it was not until later that I fully understood. Space
