Exciting discoveries are continually being made on our sister planet, Mars. NASA's rovers plus orbiting satellites have revealed many, often unexpected features. Bright ice exists only 50cm below the surface. Martian river networks formed under semiarid climates, when floods alternated with long dry spells. Liquid surface water lasted at least 10,000 years. Strange vertical shafts cutting through lava flows may be windows into lava tunnels. Could these contain life? The newly arrived Curiosity is already increasing our understanding of Martian long history.
