There was no shortage of interesting lunar science talks at last month’s Lunar and Planetary Science Conference. Dr. Ryan Clegg-Watkins highlights some of the interesting results for us.
This month (actually, today), Cassini had a relatively close flyby of Titan, and New Horizons will observe a very distant Kuiper belt object named 1994 JR1. Akatsuki has just fine-tuned its orbit around Venus, and Hayabusa2 has begun an 800-hour ion engine thrusting phase to steer it toward near-Earth asteroid Ryugu.
Welcome to my monthly inventory of the 20-plus spacecraft actively exploring our solar system. Highlights of this month include the impending launch of the ExoMars Trace Gas Orbiter and Schiaparelli lander, currently planned for March 14, and the resumption of regular VMC Mars images by Mars Express.
Here, for the first time in a format easily accessible to the public, are hundreds and hundreds of science-quality images from the Chang'e 3 lander and Yutu rover.

China plans a busy future in robotic space exploration. Besides the scientific merit, what interests me most about the upcoming Chang'e 4 mission is their intention to get the public involved.
It's official: China plans to send a lander mission to the lunar farside. A relay satellite will launch to the Earth-Moon L2 point in June of 2018, and a lander will follow at the end of 2018. The landing site may be within the south pole-Aitken basin.
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.
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.
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.
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.
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
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.
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.
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.
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.
We don’t hear a lot at the moment about Chang’E 3 and Yutu, the Chinese lander and rover which were all over the news a few months ago. But Phil Stooke has been collecting news online and in person last month at the Lunar and Planetary Science Conference and now tries to put it all together and address the current state of the mission.
