Hi
We have done a five question about the Mars and how to get your on food and how to survive in the mars on 26 mounts.
1. A mission to Mars could happen 26 months when Mars and Earth are at the closest point in their orbits.
2. Mars is know as the Red Planet because of it's colour (caused by large amounts of Iron oxide), Other features including polar Ice caps, Olympus Mons (the largest volcano in the solar system), and Valles Marineris (one of the largest canyons in the solar system)
3. The air on Earth contains a lot of oxygen (around 21 percent). Your body uses oxygen to burn fuel to make energy. On Mars, the atmosphere is 95 percent carbon dioxide. Breathing this would mean certain death because the carbon dioxide would replace the oxygen in your red blood cells. You would last round two minutes.
4. It doesn’t rain on Mars. This means the planet has no rivers or lakes. Water is found as ice in the polar icecaps, but these ice caps are covered i na thick layer of frozen carbon dioxide. Martian rovers have discovered more ice – underground. A tiny amount of water flows on the planet’s surface, but only when the temperature is warm enough, and this water is full of toxic salts. Don’t think you can just bring a supply of fresh water from Earth. Water is very heavy and takes up a lot of space. It would be an impossible task.
5. If settlers brought their own food, it would need to last for twenty-six months until the next supply rocket arrives. Each person’s supply would weigh around 5 tonnes. Again, that’s not a good use of space or rocket fuel. One obvious solution would be to grow food on Mars, but there’s no soil. Instead, the planet’s surface is covered in ground-up rock. This has too few of the nutrients that plants need. There’s also the problem of the atmosphere, which contains too much carbon dioxide. And Mars is
extremely cold. Plants won’t grow.
