China’s most bold moon mission but, Chang’e 6, entered lunar orbit in a single day on Tuesday (Might 7), setting its sights for a touchdown on the moon’s far facet to gather and return samples to Earth.
Chang’e 6 launched Might 3 from the Wenchang Area Launch Website in southern China’s Hainan province, using a Lengthy March 5 rocket to orbit and onward to a lunar trajectory. After a five-day transit to Earth’s largest satellite tv for pc, the probe carried out an engine burn starting at 10:12 p.m. EDT, Might 7 (0221 GMT, Might 8), slowing its momentum sufficient to be captured by the moon’s gravity, the China Nationwide Area Administration (CNSA) introduced in a launch.
If profitable, Chang’e 6 will solely be the second probe to land on the far facet of the moon, and the primary mission to return samples from there. Touchdown on the far facet of the moon has solely been completed as soon as earlier than, by China’s Chang’e 4, which introduced a lander-rover duo in January 2019.

The moon is tidally locked to Earth, which means it has equal orbital and rotational durations, inflicting the identical facet of the celestial physique to always face our planet. Due to this, line-of-sight communication with spacecraft on the far facet of the moon is not possible with out using extra relays.
Now that Chang’e 6 has entered lunar orbit, it would coordinate with China’s recently-launched Queqiao 2 relay satellite tv for pc to carry out orbital correction maneuvers forward of releasing the mixed lander and ascent stage from the orbiting probe for his or her upcoming touchdown try. Chang’e 6 is aiming for Apollo crater, contained in the moon’s South Pole-Aitken (SPA) basin, the place researchers imagine samples might comprise clues in regards to the moon’s early historical past and evolution.
Assuming a profitable touchdown, Chang’e 6 will acquire a focused 2 kilograms (4.4 kilos) of lunar samples from the floor, in addition to materials drilled from as much as 2 meters (6.5 ft) underground. These samples might be stowed within the Chang’e 6 lander’s ascent module, which is able to then launch and rendezvous with its probe counterpart in lunar orbit.
The samples will then be relocated to a reentry module on the Chang’e 6 orbiter, designed to guard the lunar materials throughout reentry via Earth’s ambiance, adopted by a switch burn of the probe’s engine to set the spacecraft on an Earth-return trajectory.
If all goes in response to plan, Chang’e 6’s 53-day mission will finish with the probe touching down again on Earth with samples from the moon’s far facet, and mark a significant milestone in China’s ongoing efforts for lunar exploration. Chang’e 6 is the fifth mission China has launched to the moon since 2018, and is a part of an prolonged effort by the nation to land a crew of taikonauts (Chinese language astronauts) on the moon by 2030.
This takes place alongside NASA’s personal lunar ambitions with america house company’s Artemis Program, which plans to launch a crew of astronauts across the moon in 2025, on Artemis 2, and to land a crew on the lunar floor on Artemis 3, in 2026. This has sparked feedback from U.S. officers a couple of new “house race,” together with prime NASA administrator Invoice Nelson.
