1.2Mtr Polar MTG yes it has been on the arc for 35 years and is now fixed on 13 East using two pairs of rusty molegrips. Unlike me they never groan but always perform.

What not sending a tanker to refuel it?

A little less analogue, and a lot more crap.

They say there is a helium shortage on Earth as its is. They already talking about scaling down its use in balloons seeing as they use it in hospitals and for scientific research.

No satellite stuff for the moment (aside from a 43cm minidish that was on the house already), Samsung SyncMaster T27B550 Smart TV & Monitor, and a few computers...

Did they not think to equip it with bussard collectors to pick up space-borne helium? Have they not learned anything from Star Trek? :lol:

(Okay, the Bussard collectors on a starship are for collecting hydrogen to supplement the Duterium supply, rather than helium, but hey, they're scientists, they can separate H from He!!)

The most logical method of replenishing the helium would be by the natural alpha decay of a radioactive material such as uranium. But since the telescope has used rather a lot of helium in the four years of operation, you would need an awful lot of the stuff in the first place, and have it at the Lagrange L2 position beforehand.

The other option would be to use something other than helium for the cooling process but ten years ago it was really the only option, again for the 'all in one package' launch scenario..

You'd probably find that it was more than the critical mass of Uranium to produce meaningful quantities. It would have to be refined Uranium as "shipping costs" of unrefined ore would be prohibitive!

If only they hadn't dumped a large amount on the far side of the moon a few years back.

Damn, I'd forgotten about that.

You know, I really do miss the moon in the night sky. And the lack of tides any more is a real nuisance.
