Ancient stream bed on Mars

Curiosity has been on Mars for 51 sol-days and today NASA announced it has found what looks like a concrete slab made up of rounded stones which is probably an ancient stream bed formed by hip-deep fast-moving water over thousands or millions of years. Observers have long hypothesized the canyons and river-like beds photographed from space were carved by water, but only now do researchers have on-the-ground confirmation for the first time.

mars navigation history

The most accurate navigation in history. "We had to know everything from how the iron molten lava in the center of the Earth was churning to how plate tectonic movements were affecting the wobble of the Earth to how the plasma in the atmosphere delayed the radio signals to and from the Deep Space Network stations". ..even the seemingly insignificant solar radiation pressure and thermal radiation forces acting on the spacecraft to a level equal to less than a billionth of the acceleration of gravity one feels on the Earth needed to be taken into account. This mission set a new standard for navigation accuracy for all future interplanetary missions.

mars express

The European Space Agency's Mars Express blasted off from Russia's Baikonur base today carrying the British-built Beagle 2 space probe atop a modified version of Russia's Soyuz rocket (a modified ICBM) tasked with finding water and life on Mars. Will it overcome the curse of Mars? Of 30 missions to Mars, 8 have gone as planed, a %74 Martian mission failure rate.
