There’s no safe place to camp out on Mars. But a team of researchers has identified what could be future Martian explorers’ best possible hideout: a string of lava tubes in the low-lying Hellas Planitia — an impact basin blasted into the Red Planet’s surface by ancient meteor impacts.

Every part of Mars could kill you. Its surface is arid, starved of oxygen and blasted daily with unrelenting, unfiltered solar radiation. Any future Martian explorers will put their lives in peril when they embark. NASA has decades of experience hauling oxygen, food and water beyond Earth. But that last killer, the radiation, is a harder problem to tackle.
