NASA Gets $75 Million For Europa Mission

astroengine writes "It may not be a lander or an orbiter, but its something. Europa, one of Jupiter's largest moons, has been the focus of much scrutiny over its potential life-bearing qualities. It has an icy crust over a liquid water ocean and now salts have been detected on its surface, suggesting a cycling of nutrients from the surface to the interior. This only amplifies the hypothesis that Europa not only could support basic life, it could support complex life. But how can we find out? The proposed Europa Clipper received interest at NASA HQ last year as it would optimize the science while keeping the mission budget under $2 billion. It would be a spacecraft that will be in orbit around Jupiter, but make multiple flybys of Europa to assess the moon for its habitable qualities. Now, in a bill signed by President Obama and approved by lawmakers, $75 million has been allocated (for the remainder of this fiscal year) for a 'Jupiter Europa mission.' Could it represent the seed money for the Europa Clipper? We'll have to wait and see."

Oh, that's nice. Cause an extinction level event then send information back saying no live here.

Re:$75 Million huh?

Indeed. We're a long ways away from having the technical know-how to drill through several kilometers of ice (and lets' face it, we really have no idea how thick the ice "crust" may be), either by robot or even manned mission. First things first.

I think something like Cassini–Huygens is probably the way to go. If I was in charge and had a good budget, I'd probably have two probes; a lander that could attempt some surface measurements, perhaps land near where surface ice is the youngest for possible signs of biological activity, and a seismometer onboard. The other probe would just smash into the moon to try to ring it like a gong to get some good seismic readings that ought to reveal more about the thickness of the ice crust, the depth of the liquid ocean beneath and data on the core. You would also have the main spaceship which could fly around the Jovian system for several years, get some data on some of the other cool Jovian satellites.

At some point we'll be able to get a probe to the liquid ocean on Europa, but until then we can take some good initial steps like we've done with Titan.
