China's Chang'e 5 lands on the moon to collect the 1st fresh lunar samples in decades

China has landed on the moon again — and this time the country plans to bring home some souvenirs.

Chang'e 5, China's first-ever sample-return mission, successfully touched down today (Dec. 1) in the moon's Ocean of Storms region, the China National Space Administration (CNSA) said in a statement. The state-run CGTN news channel initially announced the landing success

Chang'e 5 touched down on the moon at 10:11 a.m. EST (1511GMT, 11:11 p.m. Beijing Time) near Mons Rümker, a mountain in the Ocean of Storms (or Oceanus Procellarum), CNSA officials said. The probe deployed its solar array and antenna soon after to begin its work on the moon.

Two pieces of the four-module, 18,100-lb. (8,200 kilograms) Chang'e 5 mission hit the gray dirt today — a stationary lander and an ascent vehicle. If all goes according to plan, the lander will spend the next few days collecting about 4.4 lbs. (2 kg) of lunar material, some of it dug from up to 6.5 feet (2 meters) beneath the lunar surface.

The sample will then be transferred to the ascent vehicle, which will launch to lunar orbit and meet up with the other two Chang'e 5 elements — an orbiter and an Earth-return craft. The return vehicle will haul the moon dirt and rocks to our planet, with a touchdown planned in Inner Mongolia in mid-December. 

That will be a landmark event; pristine lunar samples have not been delivered to Earth since 1976, when the Soviet Union's Luna 24 mission came home with about 6 ounces (170 grams) of material.

Chang'e 5 just launched on Nov. 23, so it's packing a lot of action into a few short weeks. The compressed timeline is driven largely by the mission's energy needs: The Chang'e 5 lander is solar powered, so it must get all of its work done in two Earth weeks at most, before the sun sets at Mons Rümker. (One lunar day lasts about 29 Earth days, so most moon sites receive two weeks of continuous sunlight followed by two weeks of darkness.)

Chang'e 5 is the latest mission in the Chang'e program of robotic lunar exploration, which is named after a moon goddess in Chinese mythology. The Chang'e 1 and Chang'e 2 orbiters launched in 2007 and 2010, respectively, and Chang'e 3 put a lander-rover duo down on the moon's near side in December 2013.

The Chang'e 5 T1 mission sent a prototype return capsule around the moon and back to Earth in October 2014 to help prepare for Chang'e 5. And in January 2019, the Chang'e 4 lander-rover duo pulled off the first-ever soft touchdown on the moon's mysterious, largely unexplored far side. Both Chang'e 4 robots remain operational today, as does the Chang'e 3 lander.

Though Chang'e 5 has a very short operational life, the mission is designed to have a long-lasting impact. After all, scientists are still studying the 842 lbs. (382 kg) of lunar material brought to Earth by NASA's Apollo missions from 1969 to 1972.

Some of the Apollo material came from Oceanus Procellarum, a huge volcanic plain that Apollo 12 explored in late 1969. But Mons Rümker rocks formed just 1.2 billion years ago, whereas all of the samples collected by the Apollo astronauts are more than 3 billion years old.

Chang'e 5 therefore "will help scientists understand what was happening late in the moon's history, as well as how Earth and the solar system evolved," the nonprofit Planetary Society wrote in its description of the mission.

Chang'e 5 isn't the only sample-return game in town. Japan's Hayabusa2 mission is scheduled to deliver pieces of the asteroid Ryugu to Earth on Dec. 5, and NASA's OSIRIS-REx probe collected samples of the space rock Bennu in late October. The Bennu samples are scheduled to come home in September 2023.
