Yutu-2 and Chang’e-4 complete 16h lunar day on Moon
China’s Yutu-2 rover and Chang’e-4 lander have now successfully completed their sixteenth lunar day on the far side of the Moon, and have been put into hibernation for the long lunar night.
This means that both spacecraft have now worked longer on the Moon than any previous mission.
The news report, from China’s state-run press, provides only one real piece of information: Yutu-2 has now traveled a total of 424.45 meters (1,393 feet), which means it traveled about 24 meters (79 feet) during this sixteenth lunar day.
Their goal is to reach a different geological area of basalt a little over a mile away, a journey they say will take about a year.
I question that time frame however. Yutu-2 has averaged about 88 feet travel per lunar day. To go a mile at that pace will take about sixty lunar days, which is equivalent to between four and five years. The difference might be because the information at the second link is a bit unclear, and that they hope to begin entering the basalt region much sooner.
We shall just have to wait and see.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

88 feet…. over the period of about two weeks? Now that just seems glacially slow compared to the 100+ feet per Sol Opportunity was doing during her marathon run on Mars. I will admit I haven’t followed the Chinese program with anything resembling interest but now I have to ask, are they stopping at every pebble along the way? Last I checked, the Moon was a lot closer than Mars and they have a satellite bouncing communications to the space craft, so what could possibly be the bottleneck in getting the rover where they want to go? Even the two Lunakhods were cruising around up there with more alacrity than molasses trying to flow up hill.
Completely unscientific I know, but I would like to see a race between the various rovers. I’d wager even little Sojourner could outpace Yutu, provided Pathfinder’s batteries don’t prematurely die in the middle of the race.
