Planetary Radio: Rise of the Europa Underground?
Planetary Scientist Alyssa Rhoden and friends have created Destination: Europa
This week's PlanRad talks to one of the creators of a new effort to build support for the Europa Clipper, a spacecraft that would tell us far more about what's going on under that icy moon's surface.
NASA's Europa Mission Concept Rejects ASRGs -- May Use Solar Panels at Jupiter Instead
Untested technology is too risky
The Advanced Stirling Radioisotope Generator (ASRG) is no longer an option for powering a potential Europa mission. The ASRG uses Plutonium-238 to generate electricity, but is far more efficient than past RTGs.
Movie SciFi With Real Science? What a Concept!
Europa Report is available on demand and online, and in theaters on August 2
This week's Planetary Radio features the new indy film that relies on the best available science to create a thrilling and inspiring human mission to Jupiter's moon.
A few presentation slides with pretty pictures, sized to scale, of the large moons of the solar system.
I'm absolutely floored when I stop to think that our beautiful blue ocean is only one of perhaps a half dozen or more oceans on other worlds in our solar system, and only one of probably millions (or more) oceans on other Earth-like planets in our galaxy. Oceans abound!
On Thursday at noon PDT / 1900 UTC I'll report on some of my favorite findings from LPSC, and answer your questions about the latest planetary science.

Reports from the March 19 session at the Lunar and Planetary Science Conference covering eight icy moons in the outer solar system: Ganymede, Europa, Dione, Rhea, Mimas, Tethys, Enceladus, and Miranda.
Ever wonder what it would taste like if you could lick the icy surface of Jupiter’s Europa? The answer may be that it would taste a lot like that last mouthful of water that you accidentally drank when you were swimming at the beach on your last vacation.

What is the highest resolution global Jupiter mosaic that includes a satellite transit that can be assembled from Voyager images? Satellite transits are especially beautiful when the resolution is high enough for some details to be visible on the satellites so I decided to check this. And I was remarkably lucky.

Not many subjects remain for which it is possible to assemble everything that we know about it in one book. Even for those subjects for which our knowledge is limited, knowledge seems always to be expanding exponentially. This is not true, however, for the Galilean satellites of Jupiter.
Among Europa scientists there are two warring factions: the thick-icers and the thin-icers. The question is how thick is the ice shell that overlies Europa's subsurface ocean (the existence of which pretty much everyone agrees on).

I'm preparing a talk for the Pacific Astronomy and Telescope Show here in Pasadena on Sunday afternoon at 1:45. I have spent the morning putting together a slide that I have long wanted to have for presentations.

The second day of the New Horizons Workshop on Icy Surface Processes was about geology and geophysics. This long post just covers the first talk of that day.

Remember that neat picture and movie of Phobos passing by Jupiter that I posted last week? Several people asked me where Jupiter's moons were, and I just assumed that they weren't visible. I was wrong; Mars Express spotted Jupiter's moons along with the planet and Mars' moon!
