Based on activity during lunar days 1-3, Yutu-2 should have powered down for a 'nap of around five days while the Sun is high over Von Kármán crater. No confirmation yet - and perhaps the possibility of less caution as the rover has passed its design lifetime of 3 months?

No updates yet, but if Yutu-2 has taken the same kind of 'lunch break' it had during Chang'e-4 lunar days 1-3, it should be waking up around now for activity until a day before sunset over the landing site (~1500 UTC April 12).

Yutu-2 awoke at 14:04 UTC Monday April 8 following its noon nap in Von Kármán crater (powered down at 23:25 UTC April 1) during lunar day 4 of the Chang'e-4 mission. Yutu-2 has roved 170.92 metres so far. New compressed images released.

Before the Yutu-2 lunch break the rover added less than 8 metres to its total drive distance, suggesting the team have been carefully manoeuvring to use the VNIS spectrometer on selected targets (no hint of a mobility issue). VNIS field of view & instrument below.

ЦитироватьChina's lunar rover travels over 170 meters on moon's far side
 Source: Xinhua| 2019-04-09 22:07:12|Editor: Yamei
BEIJING, April 9 (Xinhua) -- China's lunar rover has driven 170.92 meters on the far side of the moon to conduct scientific exploration on the virgin territory.
The rover Yutu-2, or Jade Rabbit-2, took a "noon break" from April 2 to April 8, as the temperatures on the moon were extremely high, and continued its exploration, according to the Lunar Exploration and Space Program Center of the China National Space Administration.
The rover was sent to the Von Karman Crater in the South Pole-Aitken Basin on the far side of the moon on Jan. 3 for the Chang'e-4 mission. It has worked longer than its three-month design life.
As a result of the tidal locking effect, the moon's revolution cycle is the same as its rotation cycle, and the same side always faces the Earth.
The far side of the moon was regarded as a virgin territory with unique features, and scientists expect important discoveries.
The 135-kg Jade Rabbit-2 is the first ever rover to drive on the moon's far side, as well as the lightest rover ever sent to the moon.
The rover has scientifically examined some stones on the far side of the moon, which might help scientists find out whether they are from outer space or native to the moon.
Scientists hope Jade Rabbit-2 will travel farther to send more images of the unknown terrain, "listen" to the stories recorded in the ancient lunar rocks, and find more traces of the early history of the moon and the solar system.

Chang'e-4 lander powered down at 16:00 UTC Thursday April 11 ahead of a 4th lunar night in Von Kármán crater. Yutu-2 followed at 16:38 UTC. having totalled 178.9 metres of driving. Both craft expected to awaken on April 28.

Yutu-2 drove only ~16 metres during Day 4. No indication if this was due to bringing the VNIS instrument to bear on targets or navigating complex lunar terrain (or reduced mobility).

BEIJING, April 12 (Xinhua) -- The lander and the rover of the Chang'e-4 probe switched to dormant mode for the lunar night on Friday, with the rover traveling an accumulated 178.9 meters on the far side of the moon.

The rover Yutu-2, or Jade Rabbit-2, is expected to awaken again on April 28, and the lander to awaken the following day, according to the Lunar Exploration and Space Program Center of the China National Space Administration.

The Chang'e-4 probe made the first-ever soft-landing on the Von Karman Crater in the South Pole-Aitken Basin on the far side of the moon on Jan. 3.

As a result of the tidal locking effect, the moon's revolution cycle is the same as its rotation cycle, and the same side always faces the Earth.

The far side of the moon was regarded as a virgin territory with unique features, and scientists expect important discoveries.

A lunar day equals 14 days on Earth, and a lunar night is the same length. According to the measurements of Chang'e-4, the temperature of the shallow layer of the lunar soil on the far side of the moon dropped to as low as minus 190 degrees Centigrade, lower than data obtained by the U.S. Apollo mission on the near side of the moon.

ЦитироватьЗонд "Чанъэ-4" переведен в спящий режим
2019-04-12 16:52:50丨Russian.News.Cn

Пекин, 12 апреля /Синьхуа/ -- Посадочный модуль и луноход китайского зонда "Чанъэ-4" в пятницу перешли в спящий режим, чтобы переждать лунную ночь. Об этом сообщили в Центре лунных исследований и космической программы при Китайском национальном космическом управлении /CNSA/.

К данному моменту луноход "Юйту-2" /"Нефритовый заяц-2"/ уже преодолел путь в целом 178,9 метра на обратной стороне естественного спутника нашей планеты.

Луноход, как ожидается, "проснется" 28 апреля, а посадочный модуль - 29 апреля.

"Чанъэ-4" был запущен 8 декабря прошлого года и 3 января этого года совершил мягкую посадку на невидимой стороне Луны.

ЦитироватьChina's Chang'e-4 probe resumes work for fifth lunar day
Source: Xinhua | 2019-04-29 15:34:28 | Editor: Li Xia

BEIJING, April 29 (Xinhua) -- The lander and the rover of the Chang'e-4 probe have resumed work for the fifth lunar day on the far side of the moon after "sleeping" during the extreme cold night.

The lander woke up at 7:40 a.m. Monday, and the rover, Yutu-2 (Jade Rabbit-2), awoke at 1:45 p.m. Sunday. Both are in normal working condition, according to the Lunar Exploration and Space Program Center of the China National Space Administration.

The rover has traveled an accumulated 178.9 meters on the moon and worked about one month longer than its designed life.

China's Chang'e-4 probe, launched on Dec. 8, 2018, made the first-ever soft landing on the Von Karman Crater in the South Pole-Aitken Basin on the far side of the moon on Jan. 3.

A lunar day equals 14 days on Earth, and a lunar night is the same length. The Chang'e-4 probe switched to a dormant mode during the lunar night due to the lack of solar power.

As a result of the tidal locking effect, the moon's revolution cycle is the same as its rotation cycle, and the same side always faces Earth.

The far side of the moon has unique features, and scientists expect Chang'e-4 could bring breakthrough findings.

The scientific tasks of the Chang'e-4 mission include low-frequency radio astronomical observation, surveying the terrain and landforms, detecting the mineral composition and shallow lunar surface structure and measuring neutron radiation and neutral atoms.

The Chang'e-4 mission embodies China's hope to combine human wisdom in space exploration with four payloads developed by the Netherlands, Germany, Sweden and Saudi Arabia.

The Yutu-2 rover should, based on earlier lunar days, have powered down for a 'noon nap' around 10-15 hours ago to protect against high direct solar radiation/high temperatures. Hopefully an update on activity coming soon. Latest Yutu-2 PCAM pics below.

No upd ate on Yutu-2 activities during lunar day 5 yet (maybe due to May 1-4 labour day holiday). Based on earlier lunar days, Yutu-2 may have started its 'noon nap' ~1300 UTC May 1 & se t to resume activities ~0400 May 8. Day 5 end ~0600 UTC May 11; ahead of sunset ~0500 May 12.

The above times are merely estimates based on previous Chang'e-4 mission lunar day activities; would be interesting to see any major deviation.
