When the first astronauts land on Mars, they won't be able to take everything they need with them. The logistics and weight of transporting so much material on one spacecraft, along with a crew, defies current technology. While scientists at NASA have discussed missions to deliver materials to the Red Planet ahead of a manned mission, there may be resources on Mars that can be used. One of those key resources is water, but access to the water is just as crucial to determine. Knowing the location of accessible water on Mars could even help determine a landing site for a manned mission. A new study published this week in the journal Geophysical Research Letters shows a map of water ice that could be just an inch beneath the dusty surface.
