The Chinese Chang’e-4 lunar mission is returning data again after a scheduled two-week rest period. It’s rover, Yutu-2, woke up on January 29, but the Chang’e-4 lander slept in an extra day. The rest mode was necessary due to the frigid nighttime temperatures on the lunar far side, which plunged as low as -310 degrees Fahrenheit.

The Chang’e-4 mission is the first to explore the far side of the moon, and the cold temperatures are part of the discovery process.
