The Atmosphere

Earths atmosphere makes Earth very different from the moon or a planet without an atmosphere because it is made up of nitrogen, oxygen, carbon dioxide, water vapor and many other gases. For example the moon doesn't have an atmosphere so it receives a plentiful amount of meteorites. Unlike the Earth, the atmosphere prevents the meteorites to penetrate it because of the atmosphere. Since the atmosphere is made up of these gases, and mainly air it makes the Earth livable for any human beings.Then the development of the spectrometer allowed scientist to find other gases like Ozone and carbon dioxide.The atmosphere also has a high amount of other gases like water vapor, CO2, CH4, N2O, and SO2, which count the most in the atmosphere. Because they take in the heat emitted by the Earth.`Oxygen, to most plants and animals take oxygen directly from air, use it to release energy for their food. Without an atmosphere we wouldn't be able to live on Earth.

Space Program

Space race

• not between friends.
• between the 2 most powerful nations in the world, the U.S and the Soviet Union.
• Greatest rival to the U.S in politics and millitary powers

Began the space race

• When the soviet launched the satellite sputnik I into Orbit

The role of the competition play in the space race.

• Because it encouraged people to do more when they saw that the competitors were achieving more.
  

  

Competitors

Summaries

The Science of Rockets

This section of the article is about what an Atlas rocket is made up of. This rocket is made up of three stages, the first one is the Atlas. The Atlas uses both solid-fuel boosters and liquid-fuel engines. The second stage of the rocket is the Centaur, wich uses liquid fuel engines to maneuver into proper orbit. Finally, the third stage is the payload, which is the satellite or spacecraft carried by the rocket.

The Space Program

NASA or as you know it, The National Aeronautics and Space Administration. It begun in 1958 to explore space. Their mission was to tell whether could survive in Mercury. When that was accomplished, NASA sent up project Gemini, and then project Apollo. Then Apollos oxigen tank exploded the NASA didn't give up, they kept on sending more people.

Exploring Space Today

These days, Astronauts have something new in store for them. This new Item is a sort of robot or also known as a"Personal Satellite Assistant" . This robot stays by the astronaut, using internal fans to move around. The robot also has access to the most remote parts of the station. The assistant can also tell the astronaut the time, temperature, and could phone mission control with updates on the crew.

Using Space Science on Earth

1% of the United States of America's budget is used for the space program. Many people don't want to fund the space program, believing that the money is better spent elsewhere such as education or medical research. NASA counters saying basic knowledge of the universe gives us a better understanding of Earth, produces numerous applications in satellite communications, and that NASA supports many jobs and so is good for the economy. They also counter with the statement that space exploration is inspiration to explore the unknown and push back boundaries.
