Stories, updates, insights, and original analysis from The Planetary Society.
This is a special post for all of my readers who are lighting the first candle on their menorot this evening.
Galileo, the scientist, discovered the Galilean satellites of Jupiter four hundred years ago next month, while Galileo, the mission, arrived at Jupiter to study those moons in situ fourteen years ago Sunday.
The 126th Space Carnival is live over at Jason Perry's always-excellent (if rather narrowly focused) Io blog The Gish Bar Times.
Taking a look at Jupiter's moon, Io, from Hawaii.
As New Horizons continues its journey (it's now approaching the orbital distance of Saturn, though it's very far from that planet in space), the mission is taking advantage of the recent experience with the Jupiter flyby to plan out the science operations for the Pluto-Charon encounter.
I practically fell out of my chair when I saw this movie.
This image is beautiful for many reasons. It was captured by the MVIC imaging spectrometer, part of the Ralph instrument, on New Horizons, as it left the Jupiter system on March 2, 2007.
The last one of New Horizons imaging instruments has finally checked in with a lovely image from the Jupiter flyby
The Tvashtar eruption continues to amaze. All this time between Galileo and New Horizons, Io's volcanoes have probably continually produced spectacular eruptions like these.
There were two new pictures posted on the New Horizons Science Operations Center website this morning, of Io, and if you enhance the images a bit, there are two clear volcanic plumes visible on the limb -- Tvashtar and Prometheus are active!
A year after its launch on January 19, 2006, New Horizons is fast closing in on Jupiter, the first target on its near decade-long journey. On February 28 the spacecraft will approach to within 2.3 million kilometers (1.4 million miles) of Jupiter before speeding along on to its way to the edge of the solar system.
I got an email from John Spencer this morning telling me that the mission had posted all of New Horizons' most recently acquired images on the mission website.
New Horizons' Jupiter encounter is officially underway!
I said earlier I was going to cover the poster sessions next, and there are some cool things that I want to write about, but I thought I'd better get to something a bit more topical a bit sooner: Europa and the other Galilean satellites, and when (if!?) we'll be exploring them again.
