When the Space Age dawned in 1957, there were only two players: the USA and the USSR. The USA won the space race by being first to the Moon, though the USSR enjoyed its own successes. But here we are only a few decades later, and the USSR appears to be fading away while China is surging ahead.

Nothing’s more emblematic of China’s surge than its Tiangong space station.

Last year, astronomers warned that a large piece of debris was on a collision course with the Moon. Initially, they speculated that it was a SpaceX booster but later zeroed in on a Chinese Long March 3C rocket booster that launched the Chang’e 5 mission. When it did impact on March 4, 2022, astronomers noted a strange double crater.

A new paper suggests that it couldn’t have been a single object breaking up since there’s no atmosphere on the Moon. Instead, the booster must have been carrying an additional, undisclosed payload.

In the next decade, NASA, China, and their international and commercial partners plan to establish habitats on the Moon. Through the Artemis Program, NASA will deploy the orbiting Lunar Gateway and the Artemis Base Camp on the lunar surface. Meanwhile, China (and its partner Roscosmos) will deploy the International Lunar Research Station (ILRS), consisting of an orbital and surface element. The creation of this infrastructure will enable a “sustained program of lunar exploration and development” that could lead to a permanent human presence there.

To ensure that humans can work and live sustainably beyond Earth, astronauts and crews will need to be able to harvest local resources to see to their needs – in-situ resource utilization (ISRU). This includes using lunar water ice and regolith to grow plants, providing astronauts with food and an additional source of oxygen and biomass. To test the potential for growing plants on the Moon, a Chinese research team conducted a series of experiments where they grew tobacco plants in simulated lunar soil with the help of bacteria.

The ESA’s Gaia Observatory continues its astrometry mission, which consists of measuring the positions, distances, and motions of stars (and the positions of orbiting exoplanets) with unprecedented precision. Launched in 2013 and with a five-year nominal mission (2014-2019), the mission is expected to remain in operation until 2025. Once complete, the mission data will be used to create the most detailed 3D space catalog ever, totaling more than 1 billion astronomical objects – including stars, planets, comets, asteroids, and quasars.

Another benefit of this data, according to a team of researchers led by the Chinese Academy of Sciences (CAS), is the ability to predict future microlensing events. Similar to gravitational lensing, this phenomenon occurs when light from background sources is deflected and amplified by foreground objects. Using information from Gaia‘s third data release (DR3), the team predicted 4500 microlensing events, 1664 of which are unlike any we have seen. These events will allow astronomers to conduct lucrative research into distant star systems, exoplanets, and other celestial objects.

On January 3rd, 2019, China’s Chang’e-4 lander touched down on the far side of the Moon and deployed the Yutu rover. In addition to its many instruments, the rover carried an important science experiment known as the Biological Experiment Payload (BEP). Over the next eight days, this payload conducted a vital experiment where it attempted to grow the first plants on the Moon. Included in the payload were cotton, potato, arabidopsis, and rape seeds, along with fly eggs, yeast, and 18 ml (0.6 fluid oz) of water, which was kept at a constant atmospheric pressure.

The results of this experiment will help inform future Bioregenerative Life Support System (BLSS), which will prove vital to habitats and missions beyond Low Earth Orbit (LEO). A team of scientists from China recently released a study that reviewed the experiment, its results, and its potential implications for future missions to the Moon, Mars, and other deep-space locations. As they concluded, the experiment demonstrated that plants can grow on the Moon despite the intense radiation, low gravity, and prolonged intense light.

The China National Space Agency (CNSA) has drawn a lot of attention to its space programs in recent years. In addition to their Tiangong space station and crewed missions to Low Earth Orbit (LEO), there’s also been a lot of buzz surrounding the China Manned Space Agency (CMSA) and its Human Lunar Space Program. The high points have included the announcement of the International Lunar Research Station (ILRS) – a joint operation with Roscosmos – and shared concept art for their next-generation spacecraft and lunar lander.

As always, what we know about China’s plans for space exploration is limited to snippets of news, public statements, and the occasional video, which are the direct result of state-controlled media and tight secrecy regarding the country’s space program. The latest is a bootleg video that recently appeared online, which shows a video presentation that provides some insight into China’s long-term plans for crewed lunar exploration. The video is captioned with the words “China’s lunar space station and development of lunar molten cave base plan,” and it certainly lives up to that description!

The International Space Station (ISS) will be retired in 2030 after more than thirty-two years of continuous service. Naturally, there are questions regarding what will replace this station, which has served as a bastion for vital research and inter-agency cooperation in space. In the past, China has indicated that their Tiangong (“heavenly palace”) space station will be a successor and rival to the ISS, offering astronauts from other nations an alternative platform to conduct research in Low Earth Orbit (LEO). As part of this plan, China recently announced plans to double the size of Tiangong in the coming years.

Caves were some of humanity’s first shelters. Who knows what our distant ancestors were thinking as they sought refuge there, huddling and cooking meat over a fire, maybe drawing animals on the walls. Caves protected our ancient ancestors from the elements, and from predators and rivals, back when sticks, stones, furs and fire were our only technologies.

So there’s a poetic parallel between early humans and us. We’re visiting the Moon again, and lunar caves could shelter us the way caves sheltered our ancestors on Earth.

Last May, as part of the nation’s growing presence in space, the China National Space Agency (CNSA) announced that it had established a Human Lunar Space Program that would send crewed missions to the Moon and culminate in the creation of a lunar base. This came shortly after China and Russia announced that they would be collaborating on future lunar missions, which included the creation of a base around the southern polar region. In June 2022, they announced that this base would be named the International Lunar Research Station (ILRS) and released a guide explaining how international partners could join.

On Thursday, August 31st, the China Manned Space Agency (CMSA) released artists’ renderings of their next-generation spacecraft and lunar lander. The spacecraft will consist of two sections, a reentry capsule, and a service section, while the lunar lander will include a landing section and a propulsion section. According to a statement released by the Agency, these vehicles will deliver crews to Low Earth Orbit (LEO) and allow China to send crewed missions to the lunar surface. The release of these images confirms what has been suspected for some time: that China fully intends to land taikonauts on the Moon before 2030.

As of 2019, China began conducting preliminary studies for a crewed lunar mission that would take place by the 2030s. Two years later, the China National Space Agency (CNSA) and Roscosmos announced a partnership to create an International Lunar Research Station (ILRS) around the South Pole-Aitken Basin. The proposed timeline for development came down to three phases: Reconnaissance (2021-25), Construction (2025-35), and Utilization (2035-onward). Earlier this year, China announced that its space agency would send the first crewed mission to the lunar surface by 2030.

On July 12th, during the 9th China (International) Commercial Aerospace Forum in Wuhan, China, Chinese officials offered additional information about its crewed lunar exploration program. This included Deputy chief engineer Zhang Hailian of the China Manned Space Engineering (CMSE) office announcing the preliminary plan for China’s first crewed lunar mission. As Zhang illustrated with a series of animations, the mission will consist of two carrier rockets launching all the necessary elements to the Moon, which will then rendezvous in orbit and land on the surface to conduct science operations.
