Mars

Today we had to read a few pharghas and answer some questions about the story here are my answers.

1. When can a mission to Mars (or from Mars) happen? Every 26 months Why? Because Earth and Mars are closer at that time to travel there.
   
   

2. What are two geological features of Mars? Mars is known as the red planet because of its colour and the large amount of iron oxide. There are polar ice caps, Olympus mons the largest volcano in the solar system.
   
   

3. What is one possible solution from the story about oxygen on Mars? CO2 is made of both boron and oxygen. Nasa has made a machine called MOXIE which uses electricity to split carbon dioxide into carbon monoxide also to split water into hydrogen gas and oxygen both of these can provide oxygen for you but Both these methods can provide oxygen, but they require lots of energy.

4. If it doesn’t rain on Mars, where does the water come from? Is to dig up the underground ice and use heat to turn it into vapour. This vapour can be condensed back into water. Even though it is too cold to rain, water vapour is also present in the atmosphere on Mars.

 As the atmospheric pressure decreased over millions of years, raindrops got bigger and rainfall became heavy enough to cut into the soil and start to alter the craters.

5. How will people get food on Mars? What is a possible solution?  To get giant mirrors. These could orbit mars and direct sunlight onto the polar icecaps thawing all of the carbon dioxides Nutrients for the plants could come from recycling human waste or could be imported from Earth.
