Short updates on Akatsuki and Chang'e missions

Posted by Emily Lakdawalla on 2015/01/06 02:50 CST | 1 comments

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.

Chang'e 5 T1 rounds the lunar farside, returns lovely photo of Earth and the Moon together

Posted by Emily Lakdawalla on 2014/10/28 11:15 CDT | 3 comments

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.

Chang'e 3 update: Both rover and lander still alive at the end of their eighth lunar day

Posted by Emily Lakdawalla on 2014/07/21 07:26 CDT | 5 comments

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.

Yutu Update

Posted by Phil Stooke on 2014/04/10 03:08 CDT | 1 comments

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.

Possible hope for Yutu: "Situation is getting better," but no details [UPDATED]

Posted by Emily Lakdawalla on 2014/02/12 02:50 CST | 5 comments

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.

Bad news for Yutu rover

Posted by Emily Lakdawalla on 2014/01/25 05:33 CST | 8 comments

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.
