Stories, updates, insights, and original analysis from The Planetary Society.
NASA's Cassini spacecraft sniffed out molecular hydrogen spewing from Enceladus' subsurface ocean. The discovery means Saturn's moon has all the basic ingredients needed to support life.
Amateur image processor Ted Stryk revisited Voyager 1 data of Enceladus and came across a surprise.
For the third time in less than a decade, scientists have proposed a multiple-flyby mission to explore the habitability of Saturn’s ocean moons Titan and Enceladus.
This year’s Lunar and Planetary Science Conference devoted two oral presentation sessions to questions related to icy satellites in our solar system. Jessica Noviello reports back from the conference.
Image processing enthusiast Ian Regan produced a pretty view of Titan's lake-filled north pole, now visible to Cassini's cameras in the summer sun.
Tomorrow, Cassini will fly by Titan, picking up a gravity assist that will tilt its orbit slightly up and out of the ring plane. That will end what has been a wonderful year of frequent encounters with Saturnian moons.
The Division of Planetary Science (DPS) Meeting saw many exciting scientific discussions spanning the range of processes on different planetary bodies, as well as their replication in the laboratory and in models.
On October 28th, the Cassini spacecraft flew through the geyser plume of Saturn's moon Enceladus. But Cassini was not the only spacecraft operating in the solar system that day.
A couple of days ago, Cassini flew past Enceladus for its 20th targeted encounter. Cassini has seen and photographed quite a lot of Enceladus before, but there's still new terrain for it to cover.
The IceBreaker mission, proposed to NASA's Discovery program for low-cost missions, would seek out life on the northern plains of Mars.
The road to lower costs outer planet missions has been paved by NASA’s first two New Frontiers missions, the $700M New Horizons mission to Pluto and the $1.1B Juno mission to Jupiter. But can the cost of a mission to the outer solar system be cut to $450M, the limit for a Discovery mission?
In pictures of the planets, the stars aren't usually visible. But when they do appear, they're spectacular.
Deepak Dhingra shares some of the latest research on Enceladus' geysers presented at the American Geophysical Union (AGU) Fall Meeting in San Francisco last month.
The 45th Binghamton Geomorphology Symposium, usually focused on terrestrial studies, shifted this year to planetary science. Ted Stryk gives us an overview.
In December, scientists announced the discovery of possible plumes of water being ejected from Jupiters’s moon Europa. If confirmed, Europa would be the second moon with confirmed plumes after Saturn’s moon Enceladus. Two Discovery mission proposals for Enceladus suggest the types of missions that may be proposed for Europa.
Vignettes from dozens of LPSC talks: GRAIL and LADEE at the Moon; ice and craters and conglomerates and organics and gullies on Mars; polar deposits and volatile elements on Mercury; tectonics on Enceladus; and more, until my brain was so full I could barely speak.
In which I finally get around to writing about a paper published last August: Enceladus' plumes sometimes spout more and sometimes spout less, depending on where Enceladus is in its orbit. This discovery was enabled by Cassini's longevity at Saturn, and we'll be able to follow up on it, as long as Cassini is allowed to complete its mission.
The European Space Agency will announce two major science missions this November, one of which is likely to be devoted to solar system exploration.
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!
