Did he space out?
A landmark of human achievement.
The late legendary scientist issues one final warning for humanity.
NASA finds yet more evidence that the Red Planet might once have supported life.
Recent findings hold promise for future colonization of Mars.
With a little bit of Bradbury imagination and a giant orbital magnet, Mars could be green again.
Sand is eventually reduced to dust through wind erosion, so scientists have been searching for new sources that regenerate the sand dunes on Mars, given its lack of significant water and thin atmosphere. A new laboratory study shows small amounts of ice subjected to Martian summer temperatures and atmospheric pressure begin to boil and evaporate, levitating sand and transporting above the sediment; this type of erosion could explain the generation of new sand on the planet.
MIT was just one participant in an international competition in which teams submit proposals for Martian colonies.
