China's Yutu 2 rover has returned a view of its path over three years of travels across the harsh environment of the moon's far side.
The new images — released by Ourspace, a Chinese language science outreach channel affiliated with the China National Space Administration, in late February — give a sense of the rover's winding journey. One image offers a panorama view looking back on Yutu 2's most recent tracks, with the Chang'e 4 lander visible far in the distance. Yutu 2 touched down on the lunar far side in January 2019 atop the Chang'e 4 lander, making the pair the first spacecraft to land and operate on the moon's hidden hemisphere.
Since the duo landed, the roughly 310-pound (140 kilograms) solar-powered Yutu 2 has traveled 3,376 feet (1,029 meters) across Von Kármán crater, according to new data from China's Lunar Exploration Ground Application System.
Yutu 2 recently traveled to a crater rim to check out a "mystery hut" spotted on the horizon (which turned out to be a rabbit-shaped rock). From this vantage point, Yutu 2 can see sections of the tracks it has made in the lunar regolith, as well as its distant lander companion lower on the crater floor off to the left in the new panorama.
Meanwhile, NASA's Lunar Reconnaissance Orbiter (LRO) has been following Yutu 2 from orbit. A collection of images on webpages for LRO cameras show the landing site and the rover's movement across the surface over time.
In late 2020, Mark Robinson, a professor of geological sciences at Arizona State University and principal investigator for the imaging system on LRO, posted time-lapse imagery clearly illustrating the rover's journey to the northwest.
Yutu 2 and the Chang'e 4 lander each carry four science payloads and have far exceeded their design lifetimes of three months and one year, respectively. Each operates for about two Earth weeks when the sun shines, then powers down to outlast the long, cold lunar night. The mission's 40th lunar day began on Feb. 23 and is expected to end on Wednesday (March 9).
