Yet another reason to be horibly jealous of Don Pettit and his crewmates.
I suppose they've been sending up the latest and greatest bit of Nikon gear on every resupply mission and a decade or so later, it's like Gray's of Westminster up there.
I wonder at what point they retire them? They're not bits of kit that are ever likely to be important enough to make the cargo manifest for the ride back home, so what's going to happen all to the old gear?
Edit:
this.
