Chang'e 4 has switched to dormant mode after concluding the operations for the 26th lunar day on the Moon's far side. The lander switched to stand-by on 20 January at 21:10 BJT and the Yutu 2 rover at 14:06 BJT the same day. The pair has been working for 749 Earth days, with the rover traveling a total distance of 628.47 meters.
A new publication in Geophysical Research Letters presents the results of VNIS data: Using Yutu's Visible-Near Infrared Spectrometer (VNIS) local measurements of "thermal emission ... at short wavelengths and temperature variations at centimeter scales were retrieved during the 1st, 2nd, and 10th day of rover operations on the lunar surface. These in situ observations are an important complement to the existing large‐scale measurements taken from orbit and reveal that the millimeter scale roughness plays an important role when deriving temperatures and physical properties of the lunar surface regolith."
