Shortly after the launch of Sputnik, in the cold war era escalation of space technology, a giant aluminized mylar balloon was launched as a satellite. This was the "Echo" satellite, designed to be used as a low tech, passive low-Earth orbital relay for terrestrial telecommunications. You've seen pictures of this satellite on places like www.weirdspot.com and elsewhere for ages: Please Register or Log in to view the hidden image! Echo was BIG. but in LEO, only a few pounds of gas were sufficient to inflate it to its full diameter (30.5 m for Echo 1, 41 m for Echo 2). Which got me thinking: How practical would it be to require all future launches of space hardware to take along a small instrument package that included balloon satellites like the Echo, designed to be deployed ABOVE the debris field, and make use of a half-silvered "solar sail" to maneuver the thing so that it re-enters the atmosphere at a descent rate slow enough to allow it to capture other bits of orbiting debris and bring them back into re-entry along with it? In this manner, the cost of cleaning up the orbiting junk yard would be borne in part by those still launching satellites. Incendiary devices designed to assure that the balloons mostly incinerate upon reentry would obviously go a long way toward making such countermeasures a safe and effective means for clearing out the space lanes. The rather large re-entry profile of these devices would hopefully assure that each new launch would clear out more debris than was initially generated in the act of sending them off into space. According to the latest IEEE Spectrum (February, 2015), we are fast approaching the "Kessler Syndrome", which means that we may be unable to safely launch new spacecraft without them being damaged or knocked off course by collisions with a band of space debris still orbiting Earth from over 50 years of space conveyance. Any better ideas?
