From David Hunter
I own a salvage yard and try and do my bit to find new uses for old and discarded objects. I know that NASA will probably break their back teeth trying to say this word and probably don’t even know what it means, but let’s give it a go boys. The word is: recycle.
Has nobody thought of gathering up all the space junk (18 January, p 13) and directing it into close orbit with the International Space Station? Once in place it could be used as a shield to protect this precious project from cosmic rays and collisions with meteors and dust that could result in catastrophic failure leading to loss of human life.
It could also be scavenged for spare parts and raw materials. Have you ever tried to get your hands on a 5-millimetre nut or a sheet of aluminium when you need it in outer space? I wish I owned that cosmic junkyard, yes sir!
