  • NASA's grand plan to return to the moon, built on President George W. Bush's vision of an ambitious new chapter in space exploration, is about to vanish with hardly a whimper
  • a commercial spacecraft that could taxi astronauts into low Earth orbit
  • Obama budget as disastrous for human space fligh

    Personally I think this is great.

    what is great exactly ? No human beings will put a foot on the Moon, or Mars, in the next 22 yrs and more ... what an awful waste!
  • Francesco Biscani on 01 Feb 10
     
    Well, the constellation program was a waste of money in its current form, overrun by delays and insufficient budget. We would have had Apollo 2.0 sixty years later, for what? At least now they are talking about going to asteroids, martian moons and stuff like that.

    I agree that Constellation was a mistake. It is though a pity that now human Mars missions would certainly happen even later than initially hoped.

exoplanets spectra GJ436b Spitzer

    Spectra of the atmosphere of the planet GJ436b in the constellation Loe show evidence for carbon monoxide. Theoretical studies using numerical models however predicted that this planet's carbon inventory should be stored in the form of methane rather than CO as its temperature is estimated to be 800K. Where this inaccuracy of atmospheric models comes from is not known and has to be investigated further.

    For the first time, astronomers have discovered two distant clouds of gas that seem to be pure relics from the Big Bang.
  • LeopoldS on 12 Nov 11
     
    and one of them is in "leo" .... "This gas is of primordial composition, as it was produced during the first few minutes after the Big Bang." One gas cloud resides in the constellation Leo"

space debris tracking collisions

    New technology (STARE-a constellation of nano-satellites) for tracking satellites and space debris could improve the accuracy from 1km (current by NORAD) to less than 100m. Increasing the reliability of collision detection, preventing 99% of false warnings.

  • He then went on to remind the press that his company’s goal is to continue to lower the cost of access to space because high launch costs were “the fundamental factor preventing humanity from becoming a spacefaring civilization.”
  • First, two Falcon Heavy launches could field a return to the Moon
  • Second, a single Falcon Heavy could launch a Mars sample return mission.

  • Also possible with a single launch: a first ever human mission to an asteroid.
  • what effect Falcon Heavy might have on the costs of supporting the International Space Station. The ability to launch twice the supply capacity provided by the shuttle at something on the order of 20 percent of the cost changes the calculus entirely. So much so in fact, it opens the door for contemplating an entirely different future for ISS in which it never follows Mir into the Pacific.
  • Following conclusions offered by the Augustine Committee, the Obama Administration cancelled Project Constellation as unaffordable under existing budget limits, and supported instead the ambling, but cost-contained “flexible path.” If the Falcon Heavy is available, however, the rationale for selecting the flexible path—because it’s the only thing we can afford—simply doesn’t exist.
