WASHINGTON, March 14 — Ground-penetrating radar measurements taken by China’s lunar rover Yutu, also known as Jade Rabbit, revealed at least nine subsurface layers beneath its moon landing site, indicating that multiple geologic processes have taken place there.
Yutu is part of China’s Chang’e-3 moon mission, which delivered the rover and a stationary lander to the lunar surface on Dec. 14, 2013, marking the first moon landing since the Soviet Union’s Luna 24 mission in 1976. It touched down on the northern Mare Imbrium, also called Sea of Rains.
Yutu traveled a total of 114 meters following a zigzagging route, then came to a halt about 20 meters to the southwest of the landing site due to mechanical problems. The rover just surveyed a small area using two radar antennas capable of penetrating the Moon’s crust to depths of about 400 meters. The findings were published in the U.S. journal Science. (Xinhua)
