What's going on with our robotic planetary missions? In February I count more than 20 planetary spacecraft exploring six targets beyond Earth or cruising to new destinations.
Two images of Earth taken from different spacecraft at the same time illustrate differences in "true" color imaging among spacecraft.
Deepak Dhingra reports on a planetary analog field trip exploring a very young volcanic terrain in Idaho at Craters of the Moon National Monument and Preserve.
In its 2016 budget request, the White House inexplicably proposed to end two active, scientifically productive planetary missions: the Mars Exploration Rover Opportunity and the Lunar Reconnaissance Orbiter.
I'm back from two weeks' vacation, so it's time to catch up on the status of all our intrepid planetary missions, from Akatsuki to the Voyagers and hitting the Moon, Mars, asteroids, comets, and Saturn in between.
The New Horizons team released one more picture from Tuesday's encounter, one of three high-resolution images from a mosaic that crossed the center of Charon's disk, and it took me a while to figure out what it reminded me of.
A FOIA request offers insight into NASA's planetary science extended mission review process, which seems, at best, confusing, and at worst—with adjectival ratings like “Very Good/Good”—arbitrary.
Curiosity Rover Science Plan Slammed by NASA Review Panel
Planetary science senior review still supports continued funding
Senior review recommends continuing all major planetary exploration missions, but not without some changes.
A few people think that when it comes to the Moon, because we’ve “been there, and done that,” there is nothing new left to discover. But that viewpoint could not be farther from the truth!

Earth's brilliant colors shine above the drab lunar horizon in this new "Earthrise" photo from the Lunar Reconnaissance Orbiter. An animation that accompanied the image release helped me to write an explainer on how pushframe cameras like Lunar Reconnaissance Orbiter's Wide-Angle Camera works.
The End of Opportunity and the Burden of Success
Can NASA sustain its golden age of planetary exploration?
The Opportunity rover and the Lunar Reconnaissance Orbiter are both zeroed out in NASA's 2015 budget. Learn why these missions face the axe and why the White House is forcing NASA to choose between existing missions and starting new ones.
Earlier this week, NASA announced that it was cutting off ties with Russia, except for activities relating to the ISS. This raised questions about Russian participation on NASA's science missions, particularly the Russian experiment on the Curiosity rover.

Seeing hardware that was built by human hands sitting on the surface of another planet never, ever gets old. Today, the Lunar Reconnaissance Orbiter Camera team released two new images of Chang'e 3 and Yutu on the Moon.
Check out this unusual crater on Mars. It's not a very big one, less than 500 meters in diameter, and yet it has two rings. Most craters on Mars this size are simple bowl shapes. What's going on here?
