Writing can be fun! Now let’s have a try!
We've just had some news about the mission to explore Mars. Scientists have just said that there has been life on Mars for millions of years. Mars is a planet and it goes around the Sun．The Sun and its planets are called the solar system. The solar system is a small part of our galaxy. Mars we see at night is a long way away from us. But scientists have discovered it for many years. It is a long way away and its light has travelled for many years to reach us. It is hard to understand how far away it is from us. Scientists have sent many spacecrafts to look at Mars in order to understand
it better. So far lots of information has reached us about Mars.
