One of the main tasks of science today is also the Space research. It is connected with space flights or astronomical observations (pozorování). Automatic sounds (sondy) explore planets of our solar system. The first space ship was launched in 1961.
The first man in space was Y. Gagarin. The first man on the Moon was Neil Armstrong with Burz Aldrin in 1969. Americans use space shuttles for space flights. The space shuttle can carry from 2 to 7 people and can be used many times but its repairs are very expensive. It is lifted into space by enormous spaceship. The shuttle can carry satellites to put them into space too. There are weather satellites or military etc. Most of the space shuttles are lunched from the Kennedy Space Center in Florida.
They land at an air base in California. There are a few space shuttles‘ names in U.S.: Columbia, Enterprise, Discovery, Chalenger, Atlantis. On of the biggest catastrophe was this February. When the space shuttle Discovery was landing, it started to fire. The cause of this catastrophe was damaged shield (ocharan) against the big temperature, which are when the shuttle flies to Earth atmosphere. It could be damaged by starting. All 7 astronauts died in couple of seconds. Today the space research is not so fast. There was big fight between Soviet Union and USA who will be first e.g. in the space, on the Moon, … 50 years ago. Unfortunately Russians have not enough money so the fight is not so actual I think. It seems that the quite big rival (soupeř) will be the Chinese. They are preparing to launch their first space shuttle.
Some biological experiments can be realised in space to learn something about micro-organism, which can live in hard conditions of the space. Some micro organism can be on Mars. It can help us to learn something more about it and about the origin and the evolution of life on the Earth. It can help us to make some new chemical substances or it is possible that production of some material can be cheaper than on the Earth.
