The most interested to many about the red planet Mars is that it has a volcano
that is three times higher than Mount Everest. In some ways Mars is very familar to
Earth, which leads to the big question, is there life on Mars? Well this planet has really
fascinated astronomers for many years. Almost like Earth it has 25-hour days, volcanoes,
valleys, and polar icecaps that shrinks and expand with seasons. It is known that billions of
years ago, Mars had an atmosphere that could sustain life. over time however, the
atmosphere gradually escaped into space. Which caused the Mars to grow colder, and
now is considered a freezing desert.
