Newswise – On the long space trip from Earth to Mars “the crew won’t be able to get by with a bag lunch and Portapotty,” says biologist Arthur Teixeira. If we build a base on the moon, we?ve going to have a trash problem there too. Teixeira thinks the solution in space will be the same as it is here on Earth: recycling and compost.
Teixeira estimates the Mars trip would take six to eight months. The ship would likely remain on the planet for 18 months before Mars and Earth?s orbits would bring them close enough together for the return trip. In all, the six-person crew would be off the Earth’s surface for about three years.
