  • The US will also fund research into cleaning up the space junk that's already there.
  • Obama administration also calls for research into technologies that could remove space debris already in orbit, such as laser tractor beams.

    Team leader Professor Steven Tingay, Director of the MWA at Curtin University and Chief Investigator in the Australian Research Council Centre for All-sky Astrophysics (CAASTRO) said the MWA will be able to detect the space junk by listening in to the radio signals generated by stations including popular youth network Triple J.

  • 100 square feet;
  • NASA is, rather, testing the deployment mechanism.
  • In 2008, engineers were given just four months to devise a solar sail. They pulled it off, but the rocket carrying the sail experienced launch failure.

On whether to re-brand space junk as "historical heritage"... - 3 views

    For those working on space debris removal... Watch out for moon-protection activists that will accuse you of distroying a historical heritage: "There are countless places on Earth that have been awarded protection to preserve their historic or cultural importance. The moon has none. But that may be about to change...."

    Out-of-control Russian space probe may be 'most toxic falling satellite ever: A Russian space probe aiming to land on a Mars moon was stuck circling the Earth after equipment failure Wednesday, and scientists raced to fire up its engines before the whole thing came crashing down.

    Is it just me, or is uncontrolled space junk re-entry becoming trendy?

    this was a fantastic mission - ... what a pity!

    Really interesting bit hidden in the last paragraph: Monitoring coral bleaching from space with Envisat penetrating down to a depth of 10 m "[...] Envisat's Medium Resolution Imaging Spectrometer sensor can detect coral bleaching down to depths of ten metres, meaning Envisat could potentially map coral bleaching on a global scale."
  • Ma Ru on 15 Sep 15
     
    No, it can't :-) Since 8 April 2012 Envisat is a proud holder of the title of one of the biggest pieces of space junk out there in LEO...

    admittedly correct, so the past tense would have been a more appropriate choice... Nevertheless, plenty of data to look back at and Sentinel-3 will launch eventually! ;)

FASTSAT performing well; launch of small satellite coming next week | al.com - 0 views

shared by Joris _ on 29 Nov 10 - No Cached
  • Being able to launch a satellite from a satellite has numerous potential benefits to the military and scientists, but those benefits depend on the smaller satellite not hitting the mother ship when it launches and going where it needs to go.If the sail can deploy as planned to its 100-square-foot size - about as big as a six-person camping tent - and can guide the smaller satellite to its planned re-entry, it would also illustrate a new way to bring satellites back to Earth and reduce orbiting space junk.

    Couldn't find more details on this but sounds interesting.

    interesting indeed as a concept and to explore how far one can go to overcome some of the natural deficiencies of wood. regarding the main purpose of debris avoidance, it's typically not the structure that survives re-entry and one would have to see the environmental effect of what would be released in the atmosphere when burning.
