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, Hayabusa 2, the Chang'e program, InSIGHT, and OSIRIS-REx.
Brief updates on four ongoing missions: JAXA's Akatsuki and Hayabusa 2, and China's Chang'e 3 and Chang'e 5 test vehicle. JAXA has articulated the new science plan for Akatsuki. Hayabusa 2'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.

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.
Over the weekend, Chinese state news agency Xinhua reported in both Chinese and English a little bit more information on what has stilled the Yutu rover's motions across the lunar surface: "a control circuit malfunction in its driving unit."
During the third lunar day of Change'3 surface operations the lander operated normally, performing ultraviolet astronomy and imaging Earth's plasmasphere. The rover's instruments were working, but the rover did not move.
A terse Xinhua news report posted today says there may be some sign of life from Yutu, now that the Sun has risen on the third lunar day since Chang'e 3 landed. It is frustratingly non-specific. UPDATE: Amateur radio operators have detected a radio signal from the rover.

Promoting the story of Yutu to the Chinese public through social media: a successful case of science outreach.
As a lifetime listener of National Public Radio, it's beyond strange to hear my voice on All Things Considered! I wish it were for a happier reason, but I was invited on by Geoff Brumfiel to talk about the fate of poor Yutu.
The Sun has set for a second time at Chang'e 3's landing site on the Moon. The lander is operating normally and shut down to sleep as expected, but the rover is not responding properly to Earth command so could not prepare properly for the oncoming lunar night, and likely will not survive it.
