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.

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.

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.

Venus Express is still alive and talking to Earth, but may fall into Venus' atmosphere in January.

Venus Express is nearly out of fuel. Any day could be the last of its long mission to Venus.

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.

Venera 9 and 10 landed on Venus in 1975 and sent back the first images of the planet's surface. Now, Ted Stryk brings new life to these images to show us what it would be like to stand on the Venusian surface.

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.

Venus Express, currently the only spacecraft orbiting our nearest planetary neighbor, will soon meet a fiery end in Venus' atmosphere. But its work isn't over yet. ESA will maneuver Venus Express to dip into the uppermost Venus atmosphere and study how the spacecraft responds to atmospheric pressure, giving ESA valuable experience in aerobraking.

She’s alive! She’s alive! Or is she? A little more than a week ago, at the Lunar and Planetary Science Conference 2014, evidence was presented that Venus was geologically active, not in the recent past, like 100,000 years ago, but right now.

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.

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.
