What I've learnt from English Lessons

I've learnt many discoveries during my English lesson on the Moon & Mars. I also learnt how do people place man-made satellites in the Earth's orbit.

The Moon is our planet's (Earth) natural satellite. Scientists & many other people are contributing on how to bring people to the Moon to prevent overcrowding on Earth. So far, twelve astronauts have landed on the Moon. They have found out that the moon rocks are made of many elements such as metals & titanium. The first colonists will grow food on the moon first so when the second colonists arrive, they can eat the food straight away.

People are also trying to travel to Mars. However, they send robots instead as it is cheaper & might save human lives. They have found ice on Mars too. People will mine the ice & melt it to create water.

People might also want to travel to other planets or satellites but that is another story.
