Earth Compared to The Other Planets and Moons

Earths atmosphere is very different from all the other planets and moons. For one it can sustain life. Those that live on earth live like animals plants humans and other kinds of creatures that live on this planet of life. Second is its temperature it sustains a temperature warm and cool enough for those that live on it. In the moons and the planets they all don't have such a great atmosphere to help creatures live. Usual if a crater comes into the orbit of the planet or moon it will just hit the planet and moon and the planet or moon will have a big dent on it but for earth its atmosphere will piratically destroy the asteroid before it touches the surface. Third earth has seasons. The earth will change its temperatures so it will be colder or hotter. It will snow in the cold side or rain and it will get really hot and most likely rain every month one time. That is the difference between the planet earth and the moons and other planets in the galaxy.

NASA

Exploration of Space

In the science of the rocket there are three stages to the rockets. The satellite and rockets have been upgraded from the first satellite and rockets. They have been used for survey missions but now they are more recently used for governmental and commercial enterprises. Since the 1950's NASA used Atlas rockets. There are three stages to the rockets. First the atlas, the second stage is the centaur, the last one is the third stage, the payload. The payload is the cargo or the human going up to a satellite or the moon.
NASA is the National Aeronautics and Space Administration. It began in 1958. They had started on Project Mercury and after that Project Gemini. After the projects, although the Russians beat them in everything, they won the race to the moon. They won with the Apollo mission. Apollo 13 was then launched on April11, 1970. It never touched the moon. It had to turn around when an oxygen tank blew up so with what they had they circled the moon and then came home. The Apollo did not end the exploration on the moon. The Galileo was sent to Jupiter and took some pictures of the moon as it past it by. Prospector was put in search of possible polar ice on the moon.
We are still exploring space today. We have come up with better technology. We have come up with floating robots. It is planned for the International Space station. It is controlled by solar cells. It will help us that become astronauts by being able to tell if there is a problem in temperature. It is a small sized robot.It has been linked to mission Control on Earth. It will allow astronauts communicate with one another.
Benefits of space science is that less than one percent of the U.S. budget is going to the space program. NASA says they support many jobs and say its good for the economy. The exploration of space serves as an inspiration to humans to explore the unknown and push back boundaries.
