The earth is a very different place because we have a atmosphere. It blocks a lot of bad things. Such as they rays coming from the sun. It makes sure that we have enough and not too much. It also protects us from meteors. Which when they hit our atmosphere it burns up from all the friction from the gas that it is made up of. The ozone is a part of the atmosphere that protects us from the sun. The atmosphere is mostly made up of nitrogen it is 78%. Oxygen is 21% of it and then the other 1% is a mix of other gases. The moon has no atmosphere so there is a lot going on. Any meteor heading its way hits it. It also can very in temperature all the time.

Science Overviews

Nasa has been using Atlas rockets to get satellites into space.  The newer  ones are about 58 meters high.  Thats allot smaller than usual.  There are three parts to a rocket.  The first is an atlas which is fuel boosters.  The second is Centaur which help propel to the proper location.  The third is the payload which could be the satellite or any other load they want in space.

They started Nasa  in 1958.  They wanted to explore space.  They have been very successful many times but they also have unsuccessful.  Luckily most of the time people weren't hurt.  They have had many craft go to the moon, Apollo 13 was one of those crafts that didn't reach there goal but also reached a goal by making it back to earth without anyone getting hurt.  also Galileo made a successful flyby that helped it launch to jupiter and also got to see part of the moons north pole.

They keep creating different robots to help. One is a floating robot that can have austronaghts communicate with each other by video.  They also have a bunch of features and alerts that can tell the person.  it is is a great helper and satisfies many people.

Nasa has been saying how the government is saying it is not important.  They also only get $7 from them.  They say they help allot of people with satellites with there jobs.  Many technology stuff has been discovered by space from Nasa.  Especially in communication has grown so much by satellites.  so we need to raise many for Nasa.
