The Technological Advancements in space exploration

There have been so many advances in space exploration for example

• First people used look up at the stars and used to be happy but now people have advanced so much you can actully go up into space.
• First only dogs and robots used to go up into space because it was not that safe for humans now humans live up in space for a long time.
• First people used to think the sun used to revolve around the Earth but now we know that all the planets revolve around the sun.
• First the telescopes wouldn't be that strong so we couldn't take very clear pictures but in 1990 Hubble Space Telescope was sent now the pictures are clear. Soon Japan is also going to send up a telescope better than Hubble.
• First humans used to stay very close to the Earth but now humans have even walked on the Moon.
• First humans used stay up in space for only for 1 or 2 days but because of the International Space Station humans stay up in space for 6 months at a time.
• First only Russia and Usa were in the space race but now even developing countries like India are sending people into space.
• When astronauts or cosmonauts go into space for many months they don't need to take loads of food they just take a tiny capsule.
