NASA's Trip to Mars
By: Grace and Karmyn

To Mars From Earth and
Back

It would take roughly 6 months to travel to Mars. It would take another 6 months to travel back to Earth from Mars.

Our Spaceships
Different types of cryogenic foams are being tested to find the perfect insulation.

The spaceship should be able to hold up to 4-6 crew members.


In addition astronauts would have to stay 18-20 months before the planets realign for the trip home.Overall the trip would take roughly 2 1/2 years.
The Benefits
One of the benefits of going to Mars is getting methane. This is more convinent because they do not have to carry as much fuel.


More Benefits
Robotic and scientific missions have shown that Mars has characteristics and has histiory similar to Earth's, but there are striking diffrences that still have to be explored.
More About the Spaceship
It'll be powered by solar arrays and batteries.

The core stage will have an engine section,LH2 tank,intertank,LOX tank,and a forward skirt.
The Dangers of Travel
The moment we land on Mars the gravity and harsh climate will conspire to keep us stuck on the surface. The M.A.V represents a formidable enginering challenge, when fully loaded with fuel the ship will be too heavy to safely launch from Earth and land on Mars.
NASA's trip to Mars includes preparing astronauts to handle several months in isolation,confinement,and in a harsh environment.
One of the best ways to prepare astronauts is by observing others who also spend several months in Antarctica
More Dangers of Travel
NASA is still learning about the environment on Mars. Including radiation levels and dust. Space radiation between Earth and Mars could be a hazard to astronauts because NASA weighs radiation danger in units of cancer risk. A healthy 40 year old man stands a 20% chance of eventually dying of cancer. On Mars the risk goes up.
