Space Junk

@NickOttens @crointel @manuel.ntumba @Shashi @SpacePlaceCanada @TerryMulligan Back in 2008, when working on my (theoretical) ‘Space Junk Remediation Project’ – inspired by the James Bond flick ‘You Only Live Twice’ – I interviewed several Space Technologist/Specialists and learned of the ‘25 year rule’…which stipulates that (the agreeing parties) would build in a ‘life-span’ of 25 years (or less) to any space craft (satellite, occupied/manned, or component)…at which time its orbit would decay and (presumably) re-enter the atmosphere and burn up. It is my understanding that this rule has been adhered to (mostly), although I can not vouch for that.

Alternatively, it has been suggested that the best solutions are to either actively de-orbit orbital debris (through various means, ‘push’ the junk into a rapid decay orbit), or, re-orbit the debris (e.g., with larger objects); ‘pushing’ it further out into space (e.g., into unoccupied orbital bands, or beyond).

Failure to remediate the accumulating (and increasingly collision-prone) space debris/junk could result in the Kessler Effect/Syndrome…the only defense for which is more shielding (on rockets) which means more fuel, thus higher and higher costs for launches, etc.
