The Science of Rockets:NASA uses atlas rockets to send out probes into space and satellites to orbit since 1950. Rockets are usually 58 meterstall and has 3 major stages. The first stage is the atlas which uses different kinds of engines to launch into space. The second stage is the centaur which uses liquid duel to give proper orbit. Lastly, we have the third stage called the payload which carries the satillite or spacecraft in which dissapears in space after it's released by the centaur.
The Space Program: NASA, also known as National Aeronautics Space Administration entered our world in 1958. As soon as it was built, they thought of projects within space, whether it was being able to breathe or survive in any part of space. The first spacecraftlet off was Apillo 13 which was launched April 11th, 1970, but it failed when the oxegen tank blew up.Since 1972 there has been spacecrafts traveling after knowing the couldn't use carbon dioxide. Now, they're flying to jupiter, to the moon, and back to earth!
Exploring Space Today:Instead of using a human space unit, we use an I.S.S. An I.S.S is an international space station. It includes a small robot called a personal satellite assistant. As a circular robot floats with the astronaut its solar powered cell fans allow it to move direction. Not only that, but it has sensors that tell temperature. This is a help to astronauts because it alerts when there's a problem with in space. The most helpful thing it has is a video-phone with a light to allow communication and has a mission control on earth.
Using Space Science On Earth:Less than one precent of the U.S budget goes to the space program. Everytime NASA has a venture the economy recieves $7 in return for taxes, jobs, and schools. Many technological breakthroughs have resulted from the space program in which supports many jobs. With that, it's very good for our economy!
