advancements in space exploration

Humans have gone very far in space exploration.
ü Before humans could only look up there and admire the sky. Now we are building hotels outside Earth!
ü First humans had to take loads of food with them to space. Now astronauts can remain healthy with one tiny capsule!
ü First astronauts just spent a few minutes in space. Now they spend months there!
ü Before it was just animals and robots that went into space because humans were not brave enough. Now humans are sure of what they are doing and they go up.
ü First the space suits and oxygen supplies were not so good so we could not stay in space for very long. Now are equipment is so good we stay in space for long periods without dying or something.
ü First the space ships could only be used once and than thrown away wasting lots of hard-earned money. Now we can use them over and over again.
ü Before space travel was really risky. Now nobody is really scared of space travel.
ü Before people thought the sun orbited the earth. Now we know that all planets in the solar system orbit our sun.
ü First nobody new about the other planets. Now we know all about them.
ü First the telescopes were not to strong and you hardly could see anything clearly because of the atmosphere. Now we can see other galaxies with the Hubble space telescope.
ü First it was just USA and Russia in the space race. Now its all kinds of countries working together.
There are so many advances we have made in space exploration!
