Like Space probes are very small but fast.
WALA space probes in a book. I have learnt that Sputnik was the first successful space probe to reach space.
In 1977 the USA launched the Voyager 1 space probe. It is still in use today.In 2004 it left our solar system and is now on its way to other solar systems.By March 2010 it was 16.9 billion kilometres away from the sun.That is about the same as travelling 422 000 times around the Earth.Voyager 1 has been travelling for over 30 years and is moving at 17 kilometres per second
Hello Jack
ReplyDeleteI wonder if you could explain what it is that makes the Space Probes travel so fast? They aren't big so they don't use huge rockets or engines do they.
