What a great time for space science.
I seem to remember them coordinating a bunch of the stuff around Mars a few years ago to look at something, but unless I've missed several stories (entirely possible) this still seems relatively unusual.
It's great for science that we've got so many long-lasting probes out there now. I don't think we're launching more than in the 70s - they're just more capable and operate for years. And that gives us opportunities like this. Hooray.
