Had an alien astronomer swivelled his telescope toward them in those days, he might have found them equally promising—nurseries in the making. They were large enough to hold their gases close, swaddling themselves in atmosphere; small enough to stay solid, never swelling into gaseous giants. They were “Goldilocks planets,” our own astronomers would say: just right for life. The rest is prehistory. On Earth, the volcanoes filled the air with water vapor and carbon dioxide. -
Curiosity Sets Down Safely on Mars Six-Wheeled Robot Now Set to Begin Its Multi-Year Mission at Gale Crater
NATURE | BREAKING NEWS Curiosity sets down safely on Mars Six-wheeled robot now set to begin its multi-year mission at Gale Crater. Eric Hand 06 August 2012 PASADENA, CALIFORNIA “It’s the wheel! It’s the wheel!” NASA/JPL-Caltech Ready to roll: Curiosity's first glimpse from Gale The jubilant shout was heard over cheers and exclamations as team members with Crater. NASA’s Mars Science Laboratory — also known as Curiosity — watched the first image from their spacecraft flash up on a control room screen here at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, just minutes after it landed. The picture capped off a dramatic descent sequence that deposited the rover on the surface of Mars at 10:32 p.m. Pacific daylight time on 5 August. Although not a beautiful image — it was shot through a lens cover by the rover’s rear hazard camera — the picture was enough to show one of Curiosity’s wheels resting firmly on the Martian soil. Off in the distance, the curving horizon beckons. After an 8-month journey, Curiosity survived its violent, 7-minute fall through the thin atmosphere of Mars before touching down with a speed of less than 1 metre per second, the softest landing in Mars exploration history. The feat proved that the mission's wickedly complicated landing system was as robust as advertised. The 900-kilogram rover touched down at the bottom of Gale Crater, a 154-kilometre-wide pit the size of Kuwait, where it will begin its search for past habitable environments. -
