China’s Chang’e 6 Probe Lands on Far Aspect of the Moon
The Chang’e 6 mission is China’s second to the touch down on the lunar far facet and can retrieve samples for evaluation on Earth

China has landed on the moon’s mysterious far facet — once more.
The robotic Chang’e 6 mission touched down inside Apollo Crater, throughout the large South Pole-Aitken basin, at 6:23 a.m. Beijing Time on Sunday (June 2) , based on Chinese language house officers. It was 6:23 p.m. EDT (2223 GMT) on June 1 on the time of the touchdown. The probe “successfully landed in the pre-selected area,” China’s house company stated.
The China Nationwide House Administration (CNSA) now has two far-side landings underneath its belt — this one and Chang’e 4, which dropped a lander-rover combo onto the grey grime in January 2019. No different nation has achieved it as soon as.

And Chang’e 6 will make additional historical past for China, if all goes based on plan: The mission goals to scoop up samples and ship them again to Earth, giving researchers their first-ever up-close seems at materials from this a part of the moon.
“The Chang’e-6 mission is the primary human sampling and return mission from the far facet of the moon,” CNSA officers stated in a translated assertion. (To be clear: Chang’e 6 is a robotic, not crewed, mission.) “It involves many engineering innovations, high risks and great difficulty.”
Sampling a brand new atmosphere
Chang’e 6 launched on Might 3 with a daring and unprecedented job: haul residence samples from the moon’s far facet, which all the time faces away from us. (The moon is tidally locked to Earth, finishing one rotation on its axis in roughly the identical period of time it takes to orbit our planet. So observers right here on Earth all the time see the identical facet of our pure satellite tv for pc.)
Each lunar floor mission earlier than Chang’e 4 focused the close to facet, largely as a result of that space is less complicated to discover. It is more durable to speak with robots working on the far facet, for instance; doing so usually requires particular relay orbiters, which China launched forward of each Chang’e 4 and Chang’e 6. China’s latest moon relay satellite tv for pc, known as Queqiao-2, aided the Chang’e 6 touchdown, CNSA officers stated.
Chang’e 6 arrived in lunar orbit about 4 days after liftoff. It spent the following few weeks scrutinizing its deliberate touchdown web site and gearing up for at present’s huge occasion, which went based on plan: Chang’e 6’s lander got here down softly in Apollo Crater, leaving the mission’s orbiter, with its hooked up Earth-reentry module, circling the moon.
The lander will spend the following few days learning its environment and accumulating about 4.4 kilos (2 kilograms) of lunar grime and rock. A few of these samples shall be scooped from the floor and a few shall be dug from as much as 6.5 ft (2 meters) underground, utilizing Chang’e 6’s onboard drill.
This materials will then be launched into lunar orbit by a rocket that rode down with the lander. The pattern container will rendezvous with the Chang’e 6 orbiter, then make the lengthy trek again to Earth, finally touching down right here underneath parachutes on June 25.
Chang’e 6 can be carrying a tiny moon rover and has a wide range of scientific experiments onboard the lander.
Scientists will examine the returned materials intimately, searching for insights concerning the moon’s historical past and evolution and clues about why the lunar far facet is so completely different than the close to. The darkish volcanic seas generally known as maria are widespread on the close to facet, for instance, however are uncommon on the far facet, for causes that stay mysterious.
Researchers will probably evaluate the Chang’e 6 materials to the samples collected on the moon’s close to facet by Chang’e 5, which got here right down to Earth in December 2020. (Chang’e 5 and Chang’e 6 are sister missions, with just about an identical architectures.)
Large lunar goals
The Chang’e moon program, which is known as after the Chinese language moon goddess, has launched more and more advanced and bold missions over the previous 17 years.
Chang’e 1 and Chang’e 2 despatched orbiters to the moon in 2007 and 2010, respectively. Chang’e 3 marked China’s first journey to the lunar floor, placing a lander-rover duo on the close to facet in late 2013. Chang’e 4 landed an analogous pair on the far facet in early 2019. Chang’e 5-T1 launched a check capsule across the moon and again to Earth in 2014, proving out the gear that might get lunar samples right here safely, which Chang’e 5 did in late 2020.
And there are extra missions to come back. Chang’e 7 is scheduled to launch in 2026 to evaluate the useful resource potential of the moon’s south polar area, which is assumed to harbor massive shops of water ice. Chang’e 8, which is able to elevate off two years later, will check methods to make use of these assets on-site — constructing a construction out of lunar grime and rock, for instance.
And all of this robotic work will result in one thing even larger, if all goes based on plan: crewed missions to the moon, which China goals to begin launching by 2030. The nation desires to construct an astronaut outpost close to the south pole known as the Worldwide Lunar Analysis Station later within the 2030s, with assist from companions equivalent to Russia, Belarus and Pakistan.
America has related goals with its Artemis program, which is focusing on late 2026 for its first crewed lunar touchdown. The U.S. can be constructing a moon-exploration coalition by way of a diplomatic framework known as the Artemis Accords; greater than 40 nations have signed on thus far.
