About Mars

Mars is about half the size of Earth and similar in the way that is has seasonal changes and weather but its atmosphere is too thin for liquid water to exist.

Mars has a rocky surface and appears red in colour, which is how it got its name. Mars is named after the Roman God of war because of the blood-like colouration.

Scientists have long speculated about whether Mars could sustain life but with a lack of liquid water it is unlikely. However, some scientists believe that around 3.5 billion years ago, Mars experienced flooding but we do not know where this water came from or where it went.
