Chang’E-3 was the first moon mission managed by the China National Space Administration (CNSA) to put a robotic rover on the lunar surface. Called ‘Yutu’ (translated as ‘Jade Rabbit’), the rover was deployed on to the lunar surface after the main Chang’E-3 lander autonomously soft-landed some ~ 40 km south of crater, Laplace F, on 14 December 2013. Weighing some 120 kilograms and coming in at 150 centimetres-high approximately, Yutu has four instruments onboard (four different on the lander, too): including a camera to take 3D imagery of the lunar terrain and its geological features, two spectrometers - a VNIS (visible and near-infrared) and APXS (alpha particle and x-ray) - to measure the lunar soil composition and distribution of various elements, and a radar for measuring soil depth and other structural features (e.g. layering etc.,) underneath.

Those instruments onboard the lander during the mission were capable of carrying out further studies in imagery of the terrain, as well as observing earth’s ionosphere and other celestial objects in the clear, lunar sky above (both Yutu and the lander were also capable of ‘looking’ at each other on the surface).

Chang’E-3 marks the first controlled, soft-landing moon mission in under four decades since last visited by the Luna 24, unmanned sample-return mission back in 1976. Future missions are planned (in a reverse-wise, Chang'E mission launch): Chang’E-5 is expected to be launched in 2019 for a sample return mission to the Nearside, while Chang’E-4 is expected to be launched sometime in 2018 on a mission to the Farside of the Moon involving a lander/rover/orbiter: (as of 7 June 2017, the destination is to the southeast sector of Von Karman at 45.5S, 178.0E, which lies in the western sector of the South Pole Aitken Basin). In 2020, a permanent orbiting station is envisioned, in 2023 a sample-return mission to the Farside may occur, while in 2025 and 2027, landing missions at the lunar North and South Poles respectively are possible, too. Chang'E(?) mission numbers for each mission have yet to be announced.

  • Entered lunar orbit on 6 December 2013.
  • LADEE will be observing the dust and gaseous effects that Chang’E-3 will have on the lunar atmospheric environment.
  • Lander: Overall dry mass = 1200 kilograms. Body rests ~ 0.83 metres above the surface. Landing legs span ~ 5 metres. Powered by solar panels and a 239-Plutonium Dioxide Radioisotope Thermoelectric Generator.
  • Rover: Overall 120 kilograms in weight (carries a payload mass of 20 kilograms). Six individually-powered wheels (with rocker-bogie suspension). Powered by solar panels (with possible Radioisotope Heater Units). Slope toleration ~ 20 degrees, and capable of driving over obstacles ~ 20 centimetres. Total driving distance – expected up to 10 kilometres.
