Hubble Repair Mission At Risk
MollyB writes "According to Wired, the recent collision of satellites may put the Atlantis shuttle mission to repair Hubble in the 'unacceptable risk' status:
'The spectacular collision between two satellites on Feb. 10 could make the shuttle mission to fix the Hubble Space Telescope too risky to attempt. Before the collision, space junk problems had already upped the Hubble mission's risk of a "catastrophic impact" beyond NASA's usual limits, Nature's Geoff Brumfiel reported today, and now the problem will be worse. Mark Matney, an orbital debris specialist at the Johnson Space Center in Houston, Texas told the publication that even before the collision, the risk of an impact was 1 in 185, which was "uncomfortably close to unacceptable levels" and the satellite collision "is only going to add on to that."'"
They'll send tens of thousands of young men (and women) overseas to be shot at and kill others, but not risk seven lives to fucking further humanity and human knowledge?
I don't get it.
Be relentless!
putting a impact shield around spacecraft - but the kind of impact speeds we are talking about probably makes this uneconomical as the shield would need to be massive.
The spacecraft would have trouble getting off the ground. That's even worse than uneconomical.
some kind of automated space cleaner that went around removing debris - but we had no idea how that could possibly work or be designed
The problem with this is - if that "cleaner" gets hit by debris, you've just added to the problem instead of reducing it.
pre-emptive removal of dead satalites (no, not shooting them down from earth - attaching small moters to send them into the atmosphere) - maybe steering them into a declining orbit as the last thing they do before swithing them off
That would have been a way to keep the problem in check, and it's being done with some satellites. But usually whoever puts satellites up there is too cheap to worry about disposal, since by the time it becomes a problem, they're most likely not around anymore and don't have to worry. Yay, just let the following generations clean up the crap, just like with everything else.
The idea that we must colonise space to validate our existence is a religion, not science.
The way I look at it, we are the reproductive system for the entire biosphere. If we don't colonize other planets around different stars (let alone other rocks around this one) then all of Gaia* has failed, not just one little species.
* Please note I do not actually personify "Gaia", I just use it as a convenient and poetic label for the entire interconnected biosphere.
