We not only have to find a way to get water on the moon, so we can set up Helium 3 mining operations there, we also need to find water on Mars, if we’re ever going to be able to colonize that planet. If we do find water on Mars, that makes it more likely that we will find life on other planets in the. If we don’t, then it may mean we are virtually alone in the universe, on a unique planet.

Ker Than writes in space.com that the Martian gullies that some scientists hoped were created by liquid water might instead be the result of erosion caused by landslides, due to high winds and comet impacts. They make this assumption because the same type of gullies can be found on the moon, and we now know that these do not contain water.

We want to go to Mars to look for life and to perhaps establish a colony there, but why would anyone want to travel to hot, gaseous Venus? Astronomers think that Venus was once just like the Earth?before it experienced its own global warming. Like Mars, Venus is our near neighbor?it’s only one planet closer to the sun than we are. If we can figure out why Venus heated up, we may be able to stop the same thing happening to the Earth.

British Astronomer Royal Martin Rees thinks there’s life in space and that we’re going to find it soon. He thinks we’re going to find a simple form of life on Mars or on Jupiter’s moon Europa.

Rees reminds us that there are millions of suns and solar systems out there, and some of the planets orbiting there could definitely harbor intelligent life. Is intelligent life common, or uncommon, in the universe? Scientists are divided about this question.

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.
