Chang'e 5 test vehicle maps future sample return site
This summer the Chinese space agency has been making progress toward its planned 2017 launch of the Chang'e 5 robotic sample return mission, performing low-altitude imaging of the future landing site.
What's up in solar system exploration: August 2015 edition
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.
Latest New Horizons picture of Charon: oddly familiar
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 Sky Full of Stars
In pictures of the planets, the stars aren't usually visible. But when they do appear, they're spectacular.
Mini mission updates: Dawn in orbit; Curiosity short circuit; Rosetta image release; Hayabusa2 in cruise phase; and more
Dawn has successfully entered orbit at Ceres, becoming the first mission to orbit a dwarf planet and the first to orbit two different bodies beyond Earth. I also have updates on Curiosity, Rosetta, Mars Express, Hayabusa2, the Chang'e program, InSIGHT, and OSIRIS-REx.
A new mission for Akatsuki, and status updates for Hayabusa2 and Chang'e
Brief updates on four ongoing missions: JAXA's Akatsuki and Hayabusa2, and China's Chang'e 3 and Chang'e 5 test vehicle. JAXA has articulated the new science plan for Akatsuki. Hayabusa2's ion engines have checked out successfully. The Yutu rover is still alive on the Moon, and Chang'e 5 test vehicle has successfully tested crucial rendezvous operations in lunar orbit.
FOIA Request Sheds Light on NASA Mission Extension Process
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.

Short updates on Akatsuki and Chang'e missions
A few recent newspaper articles provide some updates on the status of Japan's Venus mission, Akatsuki, and the service module of China's Chang'e 5 test vehicle, Xiaofei. In brief: Akatsuki still plans to attempt to enter orbit in December of this year, while Chang'e 5 T1 is headed to lunar orbit. Meanwhile, the Chang'e 3 mission has released an interesting image of M101, the Pinwheel Galaxy.
A new Chang'e 3 and Yutu image archive
A treasure trove of newly released images from the Chang'e 3 program includes a photo sequence of a waxing Earth and lots of high-resolution views of rover and lander on the Moon.
Lunar Polar Volatile Puzzle
Deepak Dhingra gives an exciting update from the recent Lunar Exploration and Analysis Group (LEAG) meeting at Johns Hopkins University Applied Physics Lab (JHU-APL) in Baltimore.
Chang'e 5 test vehicle flying on to Earth-Moon L2
The Chang'e 5 test vehicle service module did not follow the sample return capsule into Earth's atmosphere. Instead, it successfully performed a divert maneuver, and is now on its way to the Earth-Moon L2 point
Chang'e 5 test vehicle "Xiaofei" lands successfully
The Chang'e 5 test vehicle landed successfully in Inner Mongolia today after an 8-day mission. It demonstrated technology that China plans to use for automated sample return by the Chang'e 5 mission in 2017.
A (Difficult) Day in the Solar System
After a bad day on the launch pad, some perspective.
Chang'e 5 T1 rounds the lunar farside, returns lovely photo of Earth and the Moon together
The Chang'e 5 test vehicle's short mission is more than half over. It has rounded the far side of the Moon and is on its way back to Earth for a planned October 31 test of lunar sample return technology. It's not a science mission -- it's an engineering mission -- but it has managed to return an absolutely iconic photo of its distant home, seen across the very unfamiliar far side of the Moon.
UPDATED: China successfully launched test mission for Chang'e 5 program today
China launched to the Moon today! The spacecraft will have a brief, 8-day mission, out to the Moon and back. It is an engineering test for the technology that the future Chang'e 5 sample return mission will need to return its precious samples to Earth.
Curiosity Rover Science Plan Slammed by NASA Review Panel
Senior review recommends continuing all major planetary exploration missions, but not without some changes.
Chang'e 3 update: Both rover and lander still alive at the end of their eighth lunar day
Despite the fact that it hasn't moved for 6 months, the plucky Yutu rover on the Moon is still alive. Its signal is periodically detected by amateur radio astronomers, most recently on July 19. A story posted today by the Chinese state news agency offers a new hypothesis to explain the failure of the rover's mobility systems.
Trundling Across the Moon
High resolution images from the Lunar Reconnaissance Orbiter Camera detail the 1973 path of the Soviet rover Lunokhod 2.
Lunar Reconnaissance Orbiter's Ongoing Adventure
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!
