Shuttle se moer gestrip! Moer nou weg! NASA soek moer!

 Engineers attaching the shuttle Discovery to its external fuel tank ran into problems Friday when an internal nut used to attach a separation bolt to the belly of the orbiter slipped out of position. Re-positioning the mis-aligned nut will require access to the shuttle's aft engine compartment, sources said, but it was not immediately clear what might be required to provide that access with Discovery not yet firmly attached to its external tank.

    Tiny rock-eating microbes could mine precious extraterrestrial resources from Mars
    and pave the way for the first human colonists. Just don't expect them to transform
    the red planet's surface into a new Earth on a short deadline, researchers say.

    Two asteroids, several meters in diameter and in unrelated orbits, will pass within the moon's distance of Earth on Wednesday, Sept. 8.
    Both asteroids should be observable near closest approach to Earth with moderate-sized amateur telescopes
    . Neither of these objects has a chance of hitting Earth.

    11 September 2010 - Occultation of Venus by the moon on your doorstep

    Re Post with extra information

    Maak `n knoop in jou selfoon om hierdie okkultasie van Venus deur die maan nie mis te loop nie. Dit is in die dag en sal maklik met `n verkyker waargeneem kan word. Selfs met die blote oog. Venus verdwyn Saterdag 11 September om 14:29 agter die maan en verskyn dan weer om 15:47.  Die sekelmaantjie gaan hoog in die hemel sit en daardie klein ligpuntjie naby hom is Venus. Sien onder vir meer spesifieke tye.
