EXPLORING THE GALAXY
First Steps The first steps were when they launched the first successful satellite called Sputnik 1. The second satellite launched was called Sputnik 2 .This satellite was used to send a dog named Laika into space .Men were curios if a living thing could survive in space .Sadly Laika did not survive. The third satellite set out was called Explorer 6.It was used to send back pictures back to Earth of Earth. the fourth satellite set out was TIROS 1.it was used to send back weather information. The fifth satellite sent out was Echo 1.this one was used to send TV signals.
Space Race As soon as the Russians sent out the first satellite the space race was on. Yuri Gagarin was the first human in space .The Russians were in lead. Yuri Gagarin orbited earth once[2500 miles] before landing. A little less then a month later Alan Shepard blasted off but returned back down[320 miles]. The next year John Glenn blasted off in the space ship called friendship 7 .He orbited three times before landing. He told everyone that earth looked like a big map. He was an American hero .the Americans were in the lead. Soon Russia caught up .they had sent out the first woman in space .
To the Moon Many people have wondered about the moon. It’s time to find out about it. The moon orbits around the earth . Apollo 7 carried three astronauts . Scientists had tested the space craft to see if it would take men to the moon. Apollo 8 proved that we could go to the moon. Three astronauts had orbited around the moon about ten times. Apollo 9 astronauts orbited earth . They tested the lunarModel. Apollo 10 flew all the way to the moon 9miles from surface. Apollo 11 landed on the moon .6 hours later Neil Armstrong took the first step on the moon. A few days later they left the moon.
The Space Shuttle The USA had made it to the moon. They were ahead in the space race . Science tests were done in labs to see what would be next. The next thing that was done was space shuttles. Soon they had made shuttles for the astronauts .
Other Planets and Beyond No people have been to other planets but many machines have. Mariner explored the atmosphere of Mars. Pioneers mission was to land on Venus. Viking landed on mars in 1997. Cassini –Huygens recently sent pictures back of Titan Saturns largest moon.
Conclusion Even know we’ve been exploring the galaxy for almost 50 years. There is so much still to learn about space and the galaxy. 1957 the first satellite sent out . 1960 first human in space. 1963 first woman in space. 1965 first space walk. 1969 first human to walk on the moon. 1981 first space shuttle mission. 1983 pioneer leaves the solar system. 1990 Hubble telescope launched. 2000 crew arrives at ISS. 2003 ISS completed Cassini-Huygens sends pictures from Saturn.
Hot’s Q’s 1. Space travel is dangerous and very expensive. Do you think it is worth it? Yes because we are learning about atmospheres and galaxies. Was Laikas death a waste? Kind of because she was a good dog and she didn’t deserve death would you be a good astronaut ? No because I would probably fall out of the spaceship . If you had the chance to explore the deep sea or deep space which would you choose and why? Both because they are both exotic and full of adventures.
