Stories, updates, insights, and original analysis from The Planetary Society.
Six scientists share the major planetary science discoveries of the past decade, and the questions that will drive the next 10 years of solar system exploration.
A Mercury meeting held May 1-3 summarized the current and future science of the innermost planet. Emily Lakdawalla was there and shares her notes.
2016 marks the 25th anniversary of the creation of what has become one of the primary venues for the publication of research in planetary science: the Journal of Geophysical Research: Planets. This occasion is a good opportunity to look back at what we have learned in this era of expanded exploration and to try to take a peek at the future.
There is one less robot exploring the solar system today. MESSENGER, which has orbited Mercury for four years, finally ran out of fuel and crashed into the planet at 17:26 UT on Thursday, April 30, 2015.
At last week's Lunar and Planetary Science Conference, the MESSENGER team held a press briefing to share results from the recent few months of incredibly low-altitude flight over Mercury's surface. The mission will last only about five weeks more.
More examples of imperfect--but tantalizing--images from deep space.
Looking ahead to what we can expect from Earth's exploration of the rest of the solar system in 2015, there's an obvious theme: Dwarf planets.
Watch as our enormous moon -- a quarter the diameter of the planet -- just winks out as it passes into Earth's long shadow, in an animation captured from more than 100 million kilometers away.
MESSENGER is revealing the first planet in sharp detail.
Van Kane explains three factors that make exploring Europa hard—factors that can make a mission concept that seems like less actually be more.
A new video shows what a traveler aboard Mercury's MESSENGER spacecraft would see as they zipped over the planet's north polar region.
The two spacecraft currently orbiting the two innermost planets are both flying low in their orbits in the final phases of their missions. MESSENGER just performed a rocket burn to raise its orbit slightly, while Venus Express did the opposite.
One day, five worlds.
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.
Animated maps of the planets show the spheres in motion.
I've been fascinated by Mercury's hollows ever since MESSENGER discovered them. Two recent papers look at where they are found to try to figure out how they form.
Striking terrain discovered by the MESSENGER probe.
With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.
Some notes from the first day of the Division for Planetary Sciences meeting on Mercury.
We have new pictures from planet one.
