Facts about mars

1. Mars’ red color is due to iron oxide, also known as rust, and has the consistency of talcum powder. Literally, the metallic rocks on Mars are rusting.
2. The atmosphere (mostly made up of carbon dioxide) on Mars is so thin that water cannot exist in liquid form—it can exist only as water vapor or ice. Liquid water is considered for many scientists to be the “holy grail” of Mars.
3. No human could survive the low pressure of Mars. If you went to Mars without an appropriate space suit, the oxygen in your blood would literally turn into bubbles, causing immediate death.
4. If you were driving 60 mph in a car, it would take 271 years and 221 days to get to Mars from Earth.
