Space Technologies

Sputnik Space ProbeSputnik 1 was the first space probe (Un-Manned mission) launched into space. It was a polished metal sphere with four external antenae attached on the bottom half of the metal sphere. Spuntik 1 was launched it into an elliptical Earh orbit on October 4th 1957. The satellite travelled at about 29,000 km/h taking 96.2 to complete each orbit. The signals from the satellite continued for about 21 days until the batterys ran out on October 26th 1957. Finally on Febuary 4th 1958 Sputnik 1 burned up in Earth's atmosphere as it fell from orbit around Earth.

Hubble Space TelescopeThe hubble space telescope was launched into a low Earth orbit in 1990, and remains there today. Hubble is outside of the distortion of Earths atmosphere which allows it to take extremely high-resolution images with almost no backround light. Even though Hubble was not the first space telescope it is among the most well known telescopes. Hubble was built by the United States space agency (NASA), with contributions from the European space agency.

International Space StationThe international space station is a space station or a habitable artificial satellite in a low earth orbit. It was a modular structure so that means that parts of the ISS were launched into space and attached together. The first component of the ISS was launched into space in 1998 now officialy the largest artificial object in space. Many parts had to be launched into space and connected to the ISS. Parts are even being launched and attached to the ISS to this day. The ISS has had contributions from many countries. Thats why the space station is named the "International" Space Station.

SatellitesA satellite is an artificial object which has been intentionally placed into orbit. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon. The world's first artificial satellite, the Sputnik 1, was launched by the Soviet Union in 1957. Since then, thousands of satellites have been launched into orbit around the Earth. Some satellites, notably space stations, have been launched in parts and assembled in orbit. Satellites are used for a large number of purposes. Common types include military and civilian Earth observation satellites, communications satellites, navigation satellites, weather satellites, and research satellites. Space stations and human spacecraft in orbit are also satellites.

TelescopesTelescopes are used to look into space. With normal human eyes it is almost impssible to see any planets in space, but with the help of telescopes and there zoomed in view it is possible to see object extremly far away. There are even telescopes in space, such as the Hubble Space Telescope. Without telescopes we would not be able to see anything space close up. The first design of a telescope for use of looking into space was made by a person named Hans Lippershey, and German lensmaker. Galileo Galilei, and Italian physicist, built his own improving Hans design.

Space ShuttlesSpace Shuttle are partially reuseable space crafts that can land and fly on earth like an airplane, but in space it will fly like a rocket. STS-1 was the first Space Shuttle launched by NASA (It also was the first one launched in the world). STS-1 was used to carry people into space. This shuttle flew around the Earth, or orbited. Space shuttles are used to train people that are becoming astronauts.

RoversA rover is a space exploration vehicle used to roam across planets surfaces or other celestial bodies. Some rovers have been designed export people from a spaceflight. A rover lands on a planet by a lander-style spacecraft. The first rover to land on mars was the Mars Pathfinder Sojourner Rover. It rolled onto Mars on July 6, 1997. This rover was a six wheeled vehicle controlled by a operator here on earth. Because of the distance to Mars, commands sent to the rover from Earth took about 10 minutes to reach it. Also, information sent back by the rover took another 10 minutes to reach Earth. The rover's mission was to gather information about the soil and rocks of Mars. Information on Sojourner Rover's performance on Mars was used to help design better robot rovers for subsequent missions.

AstronautsAstronauts are people who go into space to either explore or test experiments. Astronauts are trained by taking a space shuttle trip in "space".On April, 12 1961 Yuri Gagarin became the first human in space, making a 108-minute orbital flight in his Vostok 1 spacecraft. Since then thousands of people have became astronauts. Each one might have a different mission but every astronaut gets to some how be in space.
