The only nation active on the surface of the Moon, China, maintains successful operations of its Chang’e-3 Lander and Yutu Rover now in Lunar Night 6. Although Yutu has incurred mechanical issues, it continues to respond to ground control teams well past its 3-month given lifetime. Chang’e-3 Lander with Lunar Ultraviolet Telescope and Extreme Ultraviolet Camera, is also expected to perform past its December 14, one-year / thirteen-Lunar Day lifetime.

The spacecraft hibernate / awake cycle is determined by astronomical factors (estimated here by SPC / ILOA), mechanical functions and performance, and ground control teams at the Very Long Baseline Interferometry center in Shanghai and observation stations in Xinjiang, Kunming and Beijing.

Chang’e-4 (the twin of Chang’e-3) is being reconfigured due to the mission success; it may launch with different instruments to a new location or be combined with a future mission.

Preparing for Phase 3, the Chang’e-5 sample return mission test satellite is scheduled to launch this June to attempt a Lunar Orbit Transfer and return to Earth.

Chang’e 3 Lander and Yutu Rover Estimated Lunar Day / Night Cycle May 2014 – Jan 2015 can be found here.

  • Model Helps Search for Moon Dust Fountains

    NLSI’s DREAM team modelers help search for Moon dust fountains In exploration, sometimes you find more than what you’re looking for, including things that shouldn’t be there. As the Apollo 17 astronauts orbited over the night side of the moon, with the sun just beneath the horizon right before orbital “sunrise,” Eugene Cernan prepared to make observations of sunlight scattered by the sun’s thin outer atmosphere and interplanetary dust from comets and collisions between asteroids.
