  1. Re:Heat the space junk on Giant Balloons Could Solve Space Junk Problem · · Score: 1

    Could a land based or space based laser heat a small orbiting object relative to the 'ambient' temperature? Would that have any effect on its drag?

    No, but one of the most promising proposals for dealing with small objects does involve a ground-based laser. A very high peak power (but moderate average power) pulsed laser would zap the objects each time they came in range. The high peak power would vaporize a very tiny amount of the surface of each object each time it was hit, giving it a tiny amount of thrust. Over a period of months enough delta-v would accumlate to change the object's orbit to one that would intersect the atmosphere.

    > You will still have a very large moment arm and a decently sized moment.

    You do not, however, have any more angular momemtum. Consequently, as the baloon deploys the tumble rate decreases drastically. The peak forces should not be very large unless you were tumbling pretty fast. In most cases the craft will still have some attitude control and so won't be tumbling at all.

    Or possibly as a backup for the rockets. There are things up there that were supposed to be able to deorbit themselves before the malfunction...

    > Since aerogels are so light... ...the debris would punch right through it and keep right on going (in a slightly different and perhaps even less convenient orbit).

    To catch these objects we need something much, much more massive than they are to absorb the momentum and much, much larger to dissipate the energy. Fortunately we have such an object right at hand: the Earth. All we have to do is modify the orbits of the bits of debris slightly so that they intersect the Earth's atmosphere (because modifying the orbit of the Earth so that it intersects that of the debris would be inconvenient).

  7. Re:Not quite on Giant Balloons Could Solve Space Junk Problem · · Score: 1

    > Problem solved, no?

    No. Instantaneous vaporization == explosion. Whatever your "bullet" hit has now been blown into a thousand new bits of debris (some of them plated with bullet vapor).

  8. Re:Yes, but can they make the surface sticky? on Giant Balloons Could Solve Space Junk Problem · · Score: 1

    > What does that have to do with anything?

    It has to do with boosting hundreds of tons of your ballistic gel into orbit and then watching in horror as the energy released by the first 10km/sec bolt to hit it causes it to explode.

    Forty years ago those "geriatrics" were radical leftists, out in the streets protesting the policies of the government of the day. Forty years from now where do you think your politically-correct under thirties are going to be?

    So if I understand it, the thing does not have enough buoyancy to stay aloft without its engines, or enough engine power / the right shape to stay aloft without the helium. So what we have here is a disaster that can happen if either component fails.
