Anyone who has ever carried a bucket of water knows that it can feel quite heavy. Imagine having to transport survival amounts all the way to Mars. Not sure that rockets would get very far with that kind of a burden on board.
Scientists were therefore thrilled when “polygonal cracking and scalloped depressions” in the Martian landscape indicated the presence of subsurface ice. Better yet, this aquatic stash is present within Utopia Planitia, a “more temperate” region that bodes well for human settlement.
This discovery would not only provide future astronauts with “something to drink,” but could also yield “oxygen and hydrogen for rocket fuel.”
