2-year lunar rover travelogue issued
Print Edition
Chinese scientists published the country’s lunar rover travelogue of its first two years of service that depicted the unique and untrodden moonscape on the moon’s far side, revealing its notable differences with the near side with in situ evidence.
The study published yesterday in the peer-reviewed journal, Science Robotics, described cloddy soil, gel-like rocks, and fresh small craters inside the Von Karman crater in the South Pole-Aitken Basin.
Researchers from the Harbin Institute of Technology and the Beijing Aerospace Control Center analyzed the locomotive data and images collected by Yutu-2, offering detailed geological knowledge at the landing site that can help deepen understanding of the moon’s formation and evolution.
Chang’e-4 probe and the rover landed on the Von Karman crater on January 3, 2019. The rover has already worked for three years, surviving its initial three-month designed lifetime.
During its journey, Yutu-2 slipped and skidded, indicating the terrain it landed on is scattered with local gentle slopes, although relatively flat at large scales.
The rover, a six-wheeled off-road robot equipped with four steering motors on the corner wheels with a meshed surface, is capable of climbing up 20-degree slopes and surmounting obstacles rising up to 200 millimeters.
