A Chinese lunar rover has been sent on a mission to investigate a mysterious cube-shaped object spotted on the dark side of the moon.

The strange white object appears oddly geometric against the stark black horizon in images and prompted scientists from China’s Change 4 mission to send its Yutu 2 rover on a 2-3 month journey to check out, according to Our Space.

China’s National Space Administration (CNSA) describes the object as a “mysterious hut.”

The organization also joked that the object could be a home built by aliens following a crash landing in the Von Kármán crater in the South Pole-Aitken Basin where the rover has been navigating since January 2019.

There appears to be a small “baby” impact crater right beside the object.

Ah. We have an update from Yutu-2 on the lunar far side, including an image of a cubic shape on the northern horizon ~80m away from the rover in Von Kármán crater. Referred to as “神秘小屋” (“mystery house”), the next 2-3 lunar days will be spent getting closer to check it out. pic.twitter.com/LWPZoWN05I

Upon its discovery, scientists could not wait to send the rover to investigate further, a months-long endeavor besides only being about 262 feet away.

In July  2019, Yutu 2 made another unique discovery when it found a bizarre, colorful  “gel-like” substance ”with a mysterious luster.” The substance has not been explained.
