A robot that can scale the faces of steep cliffs might one day help explore Mars and find signs of life. The latest experiments with this "Cliffbot" showed it could help examine places otherwise difficult or impossible for astronauts to safely reach, although further improvements are needed for it to overcome obstacles, according to findings detailed in the journal Astrobiology.
