I know I wrote a while ago that I was over remote sensing, but looking at a wonderful picture by CNES this morning of the Tango satellite as seen from the Mango satellite (if I remember the details correctly) I think I may have been too hasty. It would be possible to do an archaeological survey of orbital space remotely from another spacecraft in orbit. Or many spacecraft in orbit. Sampling would be critical to get across, as the distances are just so vast, but that's a minor problem, I think.
Terrestrial tracking could be recast as a kind of archaeological survey - they're just not aware that that is what they're doing yet! Anyway this is more of a note to myself to remind me to come back to this idea. I have ten minutes before I leave for work, and this morning's task of delivering a masterclass to the graduates on conference networking. This afternoon the graduates are doing presentations on their industry work placements, there will be drinks, and if I don't imprison this thought in words now I might forget it in the awful rush of end-of-semester stuff.
Wouldn't some wealthy aerospace company like to give me job researching this kind of thing? It would make me so happy.
OK. Going to catch the bus now, in the rain.
