This does NOT mean that anything ever actually lived there. But it is the first time that the ingredients for the evolution of microbial life, and the correct conditions to support it, have been directly observed beyond Earth. Mars still has water frozen at its poles, and once had quite a bit of water above and below the surface.
What's happened in Hebes Chasma on Mars? Hebes Chasma is a depression just north of the enormous Valles Marineris canyon. Since the depression is unconnected to other surface features, it is unclear where the internal material went. Inside Hebes Chasma is Hebes Mensa, a 5 kilometer high mesa that appears to have undergone an unusual partial collapse -- a collapse that might be providing clues.
The concept of an Interplanetary Internet first came into being in 1998, about a year after the quarter-century anniversary of the design of the Internet. At the time, a man named Vint Cerf was ruminating on the future of the Internet, and with good reason; Cerf co-developed the Internet protocol suite, a set of rules (commonly known as TCP/IP) that helps orchestrate the transfer of data throughout the network of devices we call the Internet.
According to MSL scientists based at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., the ball isn't as big as it looks — it's approximately one centimeter wide. Their explanation is that it is most likely something known as a "concretion." Other examples of concretions have been found on the Martian surface before — take, for example, the tiny haematite concretions, or "blueberries", observed by Mars rover Opportunity in 2004 — and they were created during sedimentary rock formation when Mars was abundant in liquid water many millions of years ago.
Science and science fiction have done a kind of dance over the last century, particularly with respect to Mars. The scientists make a finding. It inspires science fiction writers to write about it, and a host of young people read the science fiction and are excited, and inspired to become scientists to find out more about Mars, which they do, which then feeds again into another generation of science fiction and science; and that sequence has played major role in our present ability to get to Mars. -Carl Sagan
