1. They are going to send a robot to Mars to see for any strange things. Like a sign of life. They will bring it back if they have any evidence,but if they get lots they might send people.
2.The trip will just take 6 months with the new technology.
3. They will have to have some kind of thing to exercise with. It helps them stay longer,but it doesn't always work. They also need to have the plants to drink and eat.
4. The risks are there will be less gravity so there will be less calcium in your body. That will make your bones not strong. You could also get a disease.
5. I would bring some exercise equipment. I would also bring a camera. I would also want a space suite to keep me save. I would want some thing to get the minerals in a rock.
