Crowdfunded space telescope
« on: June 20, 2013, 05:41:06 PM »

This seems very Planet Explorers-esque: Apparently the company that's pioneering asteroid mining is Kickstarting an orbital space telescope open to the public.

More interesting for me is the actual goal of that company to mine asteroids.
If they wouldn't operate in the USA (I'm from Europe) and if I had a better matching educational background I would even consider trying to get a job there.

But one thing I'm asking myself is how they plan to handle the possible threat of the Kessler Syndrome (cascading collisions in low earth orbit of satellites probably causing an event making space travel, manned and unmanned, impossible for approx. 100 years, which has become more and more probable over the last decades):

Quote
In the 2009 European Air and Space Conference, University of Southampton, UK researcher, Hugh Lewis predicted that the threat from space debris would rise 50 percent in the coming decade and quadruple in the next 50 years. Currently more than 13,000 close calls are tracked weekly.
sounds rather disturbing.

Old link....

Space is vast, while it sounds like a big number, at 100km up that is a lot of orbit circumference and that is not even accounting for the orbit radius spread, so the actual density of objects to space on a volume basis is miniscule even though it looks scary on the 2D sidebar, one pixel covers a lot of space volume!

But that is also why they want the spacescope, put it around the spaceship and in orbit to scope out near earth and asteroid objects before you hit them, because the very low probability is outweighed by the high costs of restarting the program after a lost spaceship because you did not vector away in time.  Just look at the space shuttle disasters that cost years and billions, and ultimately meant we never got to the Moon again nor Mars .
