Stories, updates, insights, and original analysis from The Planetary Society.
Exploration is teaching us a lot about the cosmos, and a lot about how much we still don’t know.
This week we're all about the rocky planets: Mercury, Venus, Earth and Mars.
How did our solar system come to be? Why are the planets, asteroids, comets, and other small worlds where they are now?
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.
I’m thrilled to be anticipating the beginning of a new mission to Mercury. Here's a timeline for BepiColombo's planned launch on 20 October (19 October in the U.S.).
Elsa Montagnon details the challenges of delivering BepiColombo’s two spacecraft from Earth to Mercury.
With my first issue of The Planetary Report as editor, I am taking the magazine open-access. Return to Mercury features articles by Elsa Montagnon on BepiColombo and by Long Xiao on the Chang'e-4 and -5 landers.
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.
Google Maps released several new map products that allow you to see the locations of named features on many solar system planets and non-planets, spinning them around in space with your mouse.
Next year, a pair of probes head to Mercury to answer outstanding questions about our innermost planet, as well as the formation of the solar system.
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.
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.
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.
