Here is some 50 year old soviet rover description.

"Lunokhod 2 was equipped with three slow-scan television cameras, one mounted high on the rover for navigation, which could return high resolution images at different rates—3.2, 5.7, 10.9 or 21.1 seconds per frame (not frames per second). These images were used by the five-man team of controllers on Earth who sent driving commands to the rover in real time.[13] There were four panoramic cameras mounted on the rover."

In real time. You can thank me later. Always Happy to educate some hans.

I didn't know Lunokhod landed on the FARSIDE and had a RELAY SATELLITE. I have to say the Indians really argue for the sake of arguing. .

Your so called 'REAL TIME CONTROL'. I am a controls engineer for god's sake, even on earth the delay between two hard wired cables is 1-2 seconds at a distance of 100m, you expect 'real time' control in space? How dumb can you be?

The Lunokhods were controlled in real-time from Earth (long article well worth reading), exactly as you say. A camera relayed images to Earth (one image every 7-20 seconds) and a five-man team (driver, commander, navigator, radio antenna operator, and the flight engineer) would control the rover.

You can imagine this was difficult: the driver has to anticipate massively due to the communications delay and the image delay. The cameras had a dead zone right in front of the rover, so the driver would also have to remember previous images (and with 1970s technology, no easy way to recall the previous image on screen).
Each team worked a two-hour stretch before being relieved.

The indian only has the bragging mouth. They lack susbtance. There is reason why they keep delay their lunar soft landing. It will never make it.

Well I don't underestimate people but Indians tend to talk before understanding something, their propensity to argue is immense. They will argue over anything, just to be 'right', you can see this cultural difference between East Asians and Indians. Chinese tend to listen first and analyze and work as a team better, Indians would argue brag and then blame when the project fails. They make good 'managers and directors' whose only game is arguing and playing politics. In India there are 9 managers to 1 worker, In China, it's the opposite.

China declares Chang'e-4 mission complete success

BEIJING, Jan. 11 (Xinhua) -- China announced Friday that the Chang'e-4 mission, which realized the first-ever soft-landing on the far side of the moon, was a complete success.

Commentary

Should this trend be confirmed, then this is really the beginning of the China Century or Pax Sinica, that will more and more likely supersede the 20th century's Pax Americana. With its current first world reserve of rare earth mineral, China could definitely put and end to the U.S. hegemony by securing the access to the North Korean rare earth that even surpass the Chinese's by tenfold. Having exhausted their rare earth mineral ore reserve during the Cold War, both the U.S.S.R. and the U.S. can no longer sustain the same pace in the hightech race with China, in the field of supercomputers, semiconductor microchips, lasers, smartphones, radars, missiles, particle accelerators, satellites, etc.. Today, China is even driving a final nail into the U.S. Dystopian Empire's coffin, by landing the Chang'e-4 lunar rover in the South Pole-Aitken Basin, the largest, deepest and oldest known crater in the solar system. Thus the best place to find rare earth mineral. The Chinese Yutu-2 lunar rover will be the first to probe it with ground-penetrating radar and measure its mineral composition with an infrared spectrometer. If rare earth mineral is present, China might find it, before any large scale industrial extraction could begin by 2030, with the first Chinese moon base.

Don't cry like a baby

You're pro US tatto @JohnWick There already a tweet from ESA for congratulation for FIRST ROVER that successfully soft landed on far side of the moon, and ranger-4 had been crash landed do know what is the mean of CRASH LANDED @JohnWick

Landing on the far side of the moon is the tip of the iceberg. More to come.

False. All isro launches are live on DD and online. Only one launch was not live in the last couple of years. That was the South Asia sat launch.
India does not try to hide its failures as its a open society.. You won't understand so I won't waste your time.

India does not try to hide its failures as its a open society。
This joke deserves respects and make me laugh!
India,an open society to rape and to kill their own daughters if they married to someone their parents do not like and an open society to drink saint bovine urine freely where the life of a cow is more important than the life of a human being..

Chang'e 4 Lander Coordinates

Following the Chang'e 4 descent frames (CNSA/CLEP) to the surface makes it easy to find the exact landing spot in a NAC image, which was taken before the landing. Note that the NAC image is rotated so north is down to match the Chang'e 4 frames. NAC M1298916428LR [NASA/GSFC/Arizona State University].​

​

Chang'e 4 safely set down on the plains of Von Kármán crater last week (3 January 2019). Soon thereafter a color image of the immediate surroundings was relayed back to the Earth from the farside! The prominent crater (about 25 meter diameter) in front of the lander can be seen just below and to the left of the bottom arrow (below).​

The Chang'e 4 spacecraft set down between the two arrows at 45.457°S, 177.589°E, plus or minus 20 meters. Full resolution (80 cm pixel scale) NAC image M1298916428LR, acquired on 8 December 2018 (before the landing), note that image is rotated 180° relative to the opening images, north is up. Image width is 880 meters [NASA/GSFC/Arizona State University].
