Destination: Europa!
It's time to reassess Europa exploration, past, present and future. The Destination Europa! session at AGU, inspired by the eponymous website and movement, didn't take exactly that message as its theme, but it's what I got from the presentations. What an ELECTRIFYING meeting this has been for Europa exploration!
Europa: No Longer a "Should," But a "Must"
We've waited long enough, Europa cries out for exploration and discovery. It's time to heed that cry.
The Plumes of Europa
2013 has been a rather exciting year for Europa scientists. Today's exciting news: the Hubble Space Telescope discovery of water vapor plumes from the south pole of this icy moon.
Planetary Radio: Rise of the Europa Underground?
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
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!
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.
Scale comparisons of the solar system's major moons
A few presentation slides with pretty pictures, sized to scale, of the large moons of the solar system.
One Ocean World Among Many
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!
Planetary Society Weekly Hangout: Reports from the Lunar and Planetary Science Conference
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.
LPSC 2013: License to Chill (or, the solar system's icy moons)
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.
Instruments for the JUICE Jovian Mission
The European Space Agency (ESA) announced the list of instruments selected for its JUICE mission to explore the Jovian system for three years starting in the 2030 following a 2022 launch.
Sea Salt
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.
Voyager 1 revisited: Io and Europa transiting Jupiter
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.
What We're Fighting For
We're fighting for the restoration of NASA's planetary sciences budget to return to its 2012 level. What does that get us? New financial analysis from our sources in the scientific community provides us a glimpse.
A couple of gems from the archives
We're still working on migrating content from the old to the new website. This week, that means I am looking, one by one, through some great amateur-processed space images.
In Honor of JUICE, a New View of Europa
To celebrate ESA's selection of the JUICE mission to Jupiter, Ted Stryk produced a new global view of Europa from Galileo data.
Pretty pictures: Voyager 2 at Jupiter
Here are two perfect examples of Voyager 2's amazing untapped treasures.
Checking up on Jupiter and Saturn
It's amateur astronomers, not professionals, who are shouldering the burden of constant monitoring of the weather on Jupiter and Saturn. What's going on these days in the outer solar system?
Book Review: Atlas of the Galilean Satellites, by Paul Schenk
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.
Is Europa's ice thin or thick? At chaos terrain, it's both!
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).
