China says its Chang’e-6 spacecraft has gathered up soil and rocks from the far side of the moon and has lifted off from the surface, beginning a journey to bring the samples back to Earth. The probe’s payload represents the first lunar samples ever collected from the far side.

In a status update, the China National Space Administration said the Chang’e-6 ascent module successfully reached lunar orbit, where it’s due to transfer the samples to a re-entry capsule hooked up to the probe’s orbiter.

If all goes according to plan, the orbiter will leave the moon’s orbit, head back to Earth and drop off the re-entry capsule for retrieval in China’s Inner Mongolia region sometime around June 25.

Chang’e-6 was launched on its mission on May 3 and landed in the South Pole-Aitken Basin region on June 2 (Beijing time). Using its drill and its robotic arm, the lander collected as much as 2 kilograms (4.4 pounds) of rocks and soil from the landing site. Meanwhile, a mini-rover rolled out onto the surface and took pictures looking back at the lander.

CNSA said scientific readings were also collected, using a lunar mineral spectrometer, a negative ion analyzer, a radon detector and a lunar structure detector. An Italian-built retro-reflector, installed on the top of the lander, served as a position control point that can be used for distance measurement. Data and telemetry were transmitted back to Earth via China’s Queqiao-2 relay satellite.

“After the collection was completed, the five-star red flag carried by the Chang’e-6 lander was successfully unfolded on the far side of the moon,” CNSA said. “This is the first time that China has independently and dynamically displayed the national flag on the far side of the moon, The flag is made of new composite materials and special technology.”

The space agency said the Chang’e-6 ascent module lifted off at 7:38 a.m. June 4 Beijing time (11:38 p.m. GMT June 3) and fired its engine for about six minutes to reach lunar orbit. After the ascent module’s rendezvous with the orbiter and the transfer of the samples, the orbiter and the re-entry capsule will continue to circle the moon, “waiting for the right time to return for the lunar-to-Earth transfer,” CNSA said. The flight plan follows the model that was set in 2020 when Chang’e-5 brought back samples from the moon’s Earth-facing side.

The findings from Chang’e-6 could provide new insights about the moon’s south polar region. That area is of particular interest because it’s thought to contain water ice reserves that could support lunar settlement. NASA is targeting the south polar region for its upcoming VIPER rover mission — and for a crewed lunar landing that’s currently scheduled for 2026. China’s space program has its own ambitions for increased lunar exploration — including another robotic mission planned for 2026, known as Chang’e-7, and a crewed landing that it’s aiming to accomplish by 2030.

The lunar surface has been a popular destination for robotic probes over the past year or so. The successful missions include India’s Chandrayaan-3, Japan’s SLIM and Intuitive Machines’ Odysseus. Russia’s Luna 25, iSpace’s Hakuto-R and Astrobotic’s Peregrine were among the not-so-successful missions.

The Artemis Program represents NASA’s effort to return to the Moon. One of the goals of the project is to set up long-term exploration of the Earth’s only natural satellite. This will need much bulkier equipment than what the Apollo astronauts carried though, and this equipment needs to be transported to the Moon’s surface. Blue Origin and SpaceX, contracted by NASA to provide human landing systems, have begun developing vehicles that can safely deliver this equipment from space to the Moon’s surface.

The Artemis program is far more ambitious than Apollo. The goal is not simply to land more humans on the moon, but to conduct scientific research, build a space station in lunar orbit, and lay a foundation for future expeditions to Mars. Artemis III, the first phase in which humans will land on the Moon, is currently expected to launch at a date no earlier than September 2026. NASA have contracted Blue Origin and SpaceX to build lander craft for Artemis III, and all future Artemis missions. The lander will dock with the lunar Gateway, bring the astronauts safely to the surface of the Moon, and then bring them back into orbit, where they will return to the Gateway station. But future Artemis missions will have much more demanding requirements, and involve much longer stays on the Moon. This will require a lot of heavy equipment that needs to be delivered from the Earth to the Moon.

“It’s essential that NASA has the capability to land not just astronauts, but large pieces of equipment, such as pressurized rovers, on the Moon for maximum return on science and exploration activities,” says Lisa Watson-Morgan, Human Landing System Program Manager at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “Beginning this work now allows SpaceX and Blue Origin to leverage their respective human lander designs to provide cargo variants that NASA will need in the future.”

Since the vehicles that can fill this requirement do not exist yet, NASA has contracted SpaceX and Blue Origin to begin designing heavy cargo versions of their human lander craft. They must be able to cope with loads with a mass of 12 to 15 tonnes, in order to fulfill mission requirements, and must be ready to fly in time for Artemis VII. NASA does not expect a completely new design, however. They expect that the cargo landers will be modified versions of the human lander. The cargo version will need to include deployment mechanisms to unload the cargo, as well as payload interfaces. They will be uncrewed, though, which means that they will not need to include heavy and complicated life support systems.

The work is currently at an early stage. Both companies are working on preliminary designs, which will be submitted for review. Feedback from this process will inform further design work, and establish a baseline from which the final detailed designs can be created.

Artemis will allow NASA to explore the moon more completely than was ever possible with Apollo. Astronauts will spend far more time on the Moon’s surface, and learn how to live and work on another world. They will conduct research on previously unexplored regions of the Moon, and lay the critical groundwork to establishing a permanent base — a vital step on the road to building a settlement on Mars. It is a highly ambitious program, combining the efforts of space agencies around the world, private companies, and the academic sector. It requires massive investment and innovation, combining the SLS (Space Launch System) rocket, the Orion spacecraft, the human and cargo landing systems, next generation space suits, pressurized rovers, and the Gateway lunar orbital space station. If successful, Artemis will mark the beginning of humanity’s settlement of deep space.

The Artemis program is supported by Space Policy Directive 1, which changed US space policy to work on a program to return humans to the Moon. It is meant to be a US-led international mission, involving the private sector, and calls on NASA to “lead an innovative and sustainable program of exploration with commercial and international partners to enable human expansion across the Solar System and to bring back to Earth new knowledge and opportunities” The goal is to build a foundation for the eventual human exploration of Mars.

Artemis 1, which launched in November 2022, was a test flight of the SLS, which ended with the Orion spacecraft splashing down into the Pacific Ocean. Artemis 2, currently scheduled for September 2025, will fly a crewed Orion spacecraft in a Lunar flyby. Artemis 3 will land astronauts on the Moon, and is planned to launch in September 2026. Artemis 4 is hoped to launch in September 2028. It will deliver the first components of the Lunar Gateway station, and also land a crew of astronauts on the Moon. Artemis 5 and 6, scheduled for 2030 and 2031, will both dock an Orion spacecraft with the Lunar Gateway, add additional segments to the station, and land astronauts on the Moon.

Here’s a familiar question: how’s the weather? We’re familiar with the weather on Earth and telescopes and missions are watching the weather on other planets in the Solar System. But for the first time in history, astronomers can now answer that question for exoplanets, located light-years away from us.

One of the Hubble Telescope's three gyroscopes started glitching recently. On June 4, NASA is likely to share an update about the device's status.
