All systems JUICE

So the SPC has done its thing. Vast petitions and stern letters nothwithstanding, they have chosen JUICE and its all systems go for launch in 2022. Jupiter here we come. The official announcement is here. There’s some coverage already at the Beeb, and at Skymania. Always quick off the mark that Suthers. Andrew Coates and Michelle Dougherty do a splendid job on the embedded video at the Beeb article and wax lyrical about Life Under The Ice. Who wouldn’t want to check that out ?

There is also an article at Physics World including quotes from yours truly. You will note I have been nice about everybody. Except NASA of course.

So thats it for now. X-rated astronomers and gravy fans have a year to gird their loins. Who wants to open a book ?

Turbulence in the gravy waves

So the Athena folk are somewhat miffed at being pipped by Juice. (This metaphor doesn’t seem quite right ? Ed.) But what about Horse Number Three ? Aren’t the NGO folk doing a Grand Petition ? Nope. It seems their tactic is a semi-formal complaint about inadeqacies in the process : an email letter direct to Gimenez. I am not sure how widely it has been circulated, but I understand it is stern stuff, bringing up issues of inappropriate revisions of costings and risk factors, and inadequately resolved conflicts of interest. Feel free to comment if you have clear knowledge, but please (a) do not leak things that are confidential, and (b) keep coments about process and not about individuals.

Its not really clear what competition means when a very small number of items is under consideration, and moreoever each item represents one community-segment, each of which ESA wishes to foster and support. Can you really leave it to peer review and some element of chance ? Nobody is both competent and neutral with respect to such huge basic choices. Why not accept that a well meaning Executive just has to  make a plan and stick with it, after taking advice ? To some extent what makes the current situation hard to swallow is the illusion of choice by peer review, rather than its weaknesses.

This wasn’t supposed to be a problem. Long standing ESA tradition is that M-class missions are genuine choices but Cornerstones / L-class missions are a slowly emerging plan. Everything gets done; its just a question of when. A year or two back, the plan was clear : we could do three halves, shared with NASA : LAPLACE, LISA, IXO. Then NASA pulled out of all of them. So now we have enough money for one and a half L-class missions instead of three. Athena, NGO, and Juice are all somewhat descoped compared to their parents. For example, ESA was going to do Ganymede and NASA would do Europa. But apparently Europa is the expensive bit because it has a horrible radiation field. So Juice will do a kind of quick day trip to Europa as I understand it, scooting back before the electronics gets fried. Anyhoo, costs are down but we still can’t do three.

We can do the usual ESA trick of slowing things down. Step round the board for a few more subscription rounds, passing GO and collecting 200 pounds each time. However, this gets you less than you think : because of standing army issues, the costs go up too. Plus, we can’t wait for ever. Its time for Cosmic Visions to finish and the next plan to emerge.

Net result : there will be an L2 competition, but no L3 competition. Things could get even tenser … NGO may seem the obvious choice to ESA because they have already invested in LISA Pathfinder, and its just a more radical advance. Thats why I think it has been really important to show that Athena serves a huge community.
