Space Exploration Summaries

The Science of Rockets:
Recent versions of the Atlas rockets contain three stages-The Atlas(uses solid and liquid fuel engines to launch the payload into space),the centaur(maneuvers ship into propor orbit)and the payload which is the satellite or spacecraft carried by the rocket.

The Space Program:
NASA was created in 1958, it's mission being human space flight, so it embarked on project Mercury to see if humans could survive in space and when that was a success, they started project Gemini where two astronauts manned a spacecraft in space. In 1970, NASA launched Apollo 13,which was a complete disaster.Since then, we have sent several un-manned spacecrafts to the moon and Jupiter.

Exploring Space Today:
ISS has a plan for a small robot to float side by astronauts in space that will monitor temperature, pressure, air quality and make sure that there are no problems in the environment.It also will have a video phone so astronauts can communicate with each other.

Using Space Science on Earth:
NASA says that less than 1% of the U.S. budget is spent on the space program and for every dollar invested, the economy receives $7 in job creation, economic growth and taxes.
