Space explore

We have been seeing in the last decades scientists working hard to develop new technologies to explore the space.
This is a great challenge because we need a lot of time to study astronomy. Furthermore the space program is expensive.
In 1969 we launchedthe first space mission to the moon. This is a historic moment in our life because the man steps on the moon for the first time.
After that scientist have been improving the studies and developing a populate space station. where a man can live for several months in the space.
Many experiments could be conducted in space station laboratories. Animals will be brought up into space to study the effects of weightlessness.
The goals are to find other planets that have condition to mea survive. To find water is the thing most important thing because we don’t have conditions to live without it. Another thing is the oxygen. We need to find a kind of mineral that is possible to extract oxygen.
We have been trying to find water on Mars, on the moon and when we find it, it can be possible for man to live out side of the earth.
