Earths Atmosphere
Earth is a very unique planet. Its the only planet that we know of that could with stain life. Most of this reason why the Earth is so unique is because of it's atmosphere. Because of earths atmosphere it has a stable weather meaning that it doesn't get to hot or to cold because the atmosphere holds heat within the earth and it keeps heat out from entering earth. It also keeps earth alive. Earth is constantly changing meaning that if you leave a foot print in dirt it would disappear over time. Unlike the moon or other planets without a atmosphere the foot print will be their forever. Also the most important thing about earths atmosphere is that it protects earth from falling debrea or asteroids or comments. When a objects enters earths atmosphere it causes a lot of friction on the object causing it to burn up the object before it the object even gets close to earths atmosphere. Because of earths atmosphere earth is very different and unique from other planets or moons in space.

Summaries
Space Exploration
Rockets are made up of three stages. The first is the atlas. The atlas uses solid fuel boosters and liquid fuel engines to launch the rocket into space. The second stage is the centaur which helps maneuver the rocket in space. The third stage is the payload, which is a space craft carrier.
Space Program
NASA was a space program that was created in 1958. It sent many astronauts to explore space. By doing this they learned a whole lot about space. They eventually sent another space craft called Apollo 13 to space to explore space more but then the oxygen tank blew up causing ciaos they had to repair the ship and get back to earth. So after that incident their sending rockets with no humans but instead are controlled by machine.
Exploring Space Today
Today we got the state of art technology. Today in space ships there is such a thing called a personal satellite assistant. It has sensors equipped so it can monitor temperature, pressure and air quality because of this personal satellite assistant it will alert astronauts with any problems. It has a video phone that will allow it to communicate with anyone in the world.
Using Space Science on Earth
NASA receives less than 1% of US spending fees. NASA says that every dollar a person donates they will return 7 dollars to the economy. They say they will create more jobs, taxes, and economic growth. But people argue that the government could spend their money on better things than space. But NASA argues that the more we know about space the better chance we have to learn more about ourselves and ways to benefit mankind.
