Hi, guys welcome back to my blog. We are starting a new Hurumanu which is science and writing. We did Science last term about Mars and this term we are learning more about mars again part two. Today we got an article from out of a journey that we had to read. If you guest it's about mars in this article it tells us all about growing food and how they get water etc. There are some questions that we had to answer so I am going to share them with you.
Questions
When can a mission to Mars (or from Mars) happen? Why?
Any mission from or two mars can happen every twenty-six months. Because the two planets would be really close together at this time.
What are the two geological features of Mars?
Mars is called a red planet because of its color and the cause is because of the large amount of iron oxide. The largest volcano on mars is called Olympus mons, and the largest canon is called Valles Marineris.
What is one possible solution from the story about oxygen on Mars?
One option is to live in caves or underground lava tubes. When they go outside they would need to wear spacesuits, and NASA is already working on a new type of spacesuit that would keep astronauts comfortable and alive.
If it doesn’t rain on Mars, where does the water come from?
People from Earth can not take water to mars because the water is very heavy and it takes up a lot of space. On Mars, it doesn't rain so astronauts get their water from the polar ice caps where their water is found as ice. People that have been on Mars have discovered more water underground, and only a little amount of water flows on the planet's surface and When it’s warm enough on mars the water is packed with toxic salts.
How will people get food on Mars? What is a possible solution?
If people were to take food to Mars it would have to last them at least twenty-six months until the next rocket of food arrives, and the amount of food for each person would weigh 5 tonnes. So the possible solution would be to use mirrors that would direct the sunlight to where the ice polar caps are. You would do this because it creates carbon dioxide which is a greenhouse gas. The heat would be used as a warm blanket. Soon after it would be warm enough for plants to grow.
