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.
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.
A higher-resolution version of the Chang'e 3 lander's panoramic view of the lunar surface has appeared on the Web, and artist Don Davis has cleaned it of artifacts to make a beautiful, seamless view. In other news, the mission has been reorganized to accommodate a possibly year-long adventure on the lunar surface.
According to news reports from China, the Yutu rover woke up from its two-week nap at 5:09 Beijing time on January 11 (21:09 on January 10, UTC), successfully establishing communication with Earth. The lander woke up autonomously at 8:21 Beijing time / 00:21 UTC on January 12, and is also "in normal condition." UPDATED to note that the lander's camera apparently did not survive lunar night.
The LRO Diviner Lunar Radiometer has been mapping the entire Moon on a nearly continuous basis since July, 2009. The Diviner team has produced maps of the thermal behavior and and a range of derived quantities at Chang’e 3 landing site that are described in this post.
With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.
As promised, Lunar Reconnaissance Orbiter's sharp eyes spotted the Chang'e 3 lander and Yutu rover on the lunar surface on December 25. The hardware shows up as a few bright pixels throwing long, dark shadows, clearly visible in a before-and-after comparison.
There was a lot of action on Chang'e 3 over the weekend! I have lots of pictures to share, including the highest-quality one I've seen of the rover on the surface, plus video of the rover making tracks on the Moon and a 3D view of the lander.
