I understand that there was a 'heat leak', not a leak of cryogenic helium. A physical leak can be fixed easily, but the heat leak would presumably have needed a redesign.Flying with the heat leak would have increased the consumption of helium, and so reduced the lifetime of the experiment. With the shuttle fleet retiring, they really didn't have any choice but to go with a permanent magnet.All this from a bit of googling - I'm not in the space industry.

The AMS is now a big gamble that has significantly damaged its own odds by downgrading its technology. Then again a method for topping up the refrigerant might have been devised to extend the life of the magnet rather than eliminating it. It seems a waste of opportunity to spend 1.5bn on a very important cosmological experiment, that could reveal a great deal more than is currently agreed to as being known about the universe, its origins and its destiny, and elminate what could prove to be a very important component.

Can you back up that allegation with evidence?

If it hadn't been defective it would have flown.

You can transfer pro-rata to hospital beds, malaria prevention, funding Obama's re-election in 2012 or whatever, but none of that is realistic, because that's not where the money would go. You could even compare it to the money that Philip Green's family made out of acquiring BHS.My personal belief is that, once we give up on pure science, we're doomed as a species. I'm glad to see that the UK AMS will live on. I'm just as glad to see that the Chinese AMS will get out there. It's definitionally impossible to predict what it will find, and it's possible that it will find nothing of any financial consequence whatsoever. But we wouldn't know if we didn't try it.

Only hope it all goes well after this, but would be very exciting to see what results we get. Might even be able to find God up there!

Once they've got it swapped up the result's the same.

Doing so made me realise how much I value it. Great article! Please keep them coming.The AMS was unknown to me before reading this article. Thanks for the links. Interesting that it works in about the same particle energy range ("multi TeV") as the LHC, though of course without the collisions and big detectors.In the distant past I worked a little on cosmic ray physics experiment trying to determine the nature of the ultra-high energy particles from the big splash they make when they hit the atmosphere. Having a big sensitive detector above the atmosphere to directly measure the primary particles over long periods of time, albeit those of relatively modest energy, is very exciting. My guess is that the probability of significant physics coming out of this project is high. Fri 27 Aug 2010 06:33:56 GMT+1
