Is Europa really the "highest priority" of the community?, Cleave said it was at LPSC? Options

[mcaplinger]

From Emily's LPSC blog: "Bob Pappalardo would not sit down until he got Cleave to acknowledge that Europa is the consensus highest priority of the planetary science community."

Cleave was obviously poorly prepared for this session, but I don't see that this acknowledgement is either meaningful or particularly accurate. If Europa were the "highest priority" of the PS community as a whole, then one might wonder why we were spending all this money on Mars. I could easily imagine that Europa is the highest priority of the outer planets community, but frankly I was surprised when Europa Orbiter appeared in the '07 budget (presumably the result of some serious lobbying on someone's part.) It was pretty obvious to me then that there would be no money for it, especially in the aftermath of JPL running the old EO project into the ground with cost overruns and engineering upscopes. (And JIMO is best forgotten.)

Don't get me wrong, I would love to be involved with a Europa mission (we did what I think was a good proposal design for EO) but I don't see either the money or the political support being there in the near term. I know it's frustrating, but one has to be realistic, and it might help to avoid the aura of entitlement that I perceive is building in some parts of the community (not referring to you, Bob). Of course, I am just a lowly engineer.

One last point.


Viking was scaled down from original plans to use Saturn 1B or even a Saturn V for a multi launch of a much larger probe.

Voyager was the scaled down compromise when TOPS was canceled in the early 70s.

NEAR was the 150 million dollar scaled down compromise when the endlessly studied 500 million dollar JPL asteroid mission couldn't get a new start.







OK, I lied. Just two more points.


I agree with the "modern orbiter" argument. Can you imagine what multiple flybys of Europa could accomplish with a HIRISE ????????

I admit we're talking a bit over the New Fronteirs budget. But we are not talking flagship costs.

Imagine such a vehicle making multiple passes of Io. .... live volcanos, direct sampling of the plumes ..... congressmen love pretty pictures, and the public may not care the least about gravity field mapping, but they understand massive volcanoes.
