China continues to establish new milestones in space. In recent years, the China National Space Agency (CNSA) has begun assembling the Long March-9 (CZ-9), the country’s first reusable super-heavy launch vehicle; the Tianwen-1 mission became the first Chinese orbiter, lander, and rover combination to reach Mars, and their super-secret spaceplane completed its second flight (after spending 276 days in space). China has also made significant progress in terms of human spaceflight, especially where the Tiangong space station is concerned.

Earlier this week (Tues. May 30th), the China Manned Space Agency (CMSA) took another major step when it launched the country’s sixteenth mission (Shenzou-16) to Tiangong atop a Long March-2F (CZ-2F) rocket. This mission delivered three taikonauts to the space station and performed the most complicated docking maneuver ever attempted. The mission highlights included successfully testing the Shenzou’s upgraded instruments and systems, which allowed the spacecraft to autonomously rendezvous with the station under less-than-ideal conditions.

As NASA prepares to return astronauts to the Moon with Artemis III, China is ramping up its efforts for a crewed lunar landing, targeting earlier than 2030. Lin Xiqiang, the deputy director of China’s Manned Space Agency announced that the Chinese Lunar Exploration Program (CLEP) is preparing for a “short stay on the lunar surface and human-robotic joint exploration.”

Glass Fibers in Lunar Regolith Could Help Build Structures on the Moon

Through the Artemis Program, NASA plans to send the first astronauts to the Moon in over fifty years. Before the decade is over, this program aims to establish the infrastructure that will allow for a “sustained program of lunar exploration and development.” The European Space Agency (ESA) also has big plans, which include the creation of a Moon Village that will serve as a spiritual successor to the International Space Station (ISS). China and Roscosmos also came together in June 2021 to announce that they would build the International Lunar Research Station (ILRS) around the lunar south pole.

In all cases, space agencies plan to harvest local resources to meet their construction and long-term needs – a process known as In-Situ Resource Utilization (ISRU). Based on samples returned by the fifth mission of the Chinese Lunar Exploration Program (Chang’e-5), a team of researchers from the Chinese Academy of Sciences (CAS) identified indigenous glass fibers for the first time. According to a paper they authored, these fibers were formed by past impacts in the region and could be an ideal building material for future lunar bases.

China Has its Own Secret Space Plane, and it Just Landed

A lot has changed since the last Space Age. Unlike the days of Sputnik, Vostok, Mercury, and Apollo, the current era is not defined by two superpowers constantly vying for dominance and one-upmanship. More than ever, international cooperation is the name of the game, with space agencies coming together to advance common exploration and science goals. Similarly, there is the way the private space sector has become a major participant, providing everything from launch services and commercial payloads to satellite constellations and crews.

But in some ways, old habits die hard. Since the turn of the century, China has emerged as a major power in space, to the point of becoming a direct competitor with NASA’s human space programs. For the past few years, China has been developing a reusable autonomous spaceplane to compete with the X-37B Orbital Test Vehicle (OTV). Known as Shenlong (“divine dragon”), this spaceplane recently concluded its second test flight after spending 276 days in orbit. Though the details are scant, the Chinese state media company Xinua declared the flight a breakthrough for the Chinese space program.

China's Mars Rover Finds Recent Evidence of Water Near the Equator

The surface of Mars is a pretty desolate place at first glance. The soil is many times as dry as the driest desert on planet Earth, the temperatures swing from one extreme to the other, and the air is incredibly thin and toxic. And yet, there’s ample evidence that the planet was once much warmer and wetter, with lots of flowing and standing water on its surface. Over time, as Mars’ atmosphere was slowly stripped away, much of this water was lost to space, and what remains is largely concentrated around the poles as glacial ice and permafrost.

For years, space agencies have been sending robotic landers, rovers, orbiters, and aerial vehicles to Mars to learn more about when this transition took and how long it took. According to China’s Tianwen-1 mission, which includes the Zhurong rover, there may have been liquid water on the Martian surface later than previously thought. According to new research from the Chinese Academy of Sciences (CAS), the Zhurong rover observed salt-rich dunes in the Utopia Planitia region that showed cracks and crusts, indicating the possible presence of water as recently as a few hundred thousand years ago.

China is Planning to Land Humans on the Moon by 2030 as Part of its Ambitious Lunar Agenda

Weiren Wu, the Chief Designer of the Chinese Lunar Exploration Program (CLEP), recently announced an ambitious plan to put Chinese footprints on the lunar surface by 2030. This announcement came just prior to this year’s Space Day of China, an annual event celebrated on April 24^thmeant to showcase the space industry achievements of the China National Space Administration (CNSA).

The China National Space Agency (CNSA) has made considerable progress in recent years with the development of its Long March 5 (CZ-5) rocket and the completion of its Tiangong-3 space station. The agency also turned heads when it announced plans in June 2021 to create an International Lunar Research Station (ILRS) that would rival the Artemis Program. On top of all that, China upped the ante when it announced later that month that it also had plans to send crewed missions to Mars by 2033, concurrent with NASA’s plans.

As part of their growing efforts to become a major power in space, which includes human exploration, China recently announced the completion of the first in-orbit test of a Stirling thermoelectric converter. The Shenzou-15 mission crew performed the test aboard Tiangong-3, and it was the first successful verification of the technology in space. This technology is also being investigated by NASA and is considered a technological solution to the challenges of space exploration, especially where long-duration stays and missions to locations in deep space are concerned.

China Hints at its Goals for a Lunar Base

In June 2021, China announced it was partnering with Russia to launch a lunar exploration program that would rival NASA’s Artemis Program. This program would include robotic landers, orbiters, and crewed missions that would culminate with the creation of an outpost around the Moon’s southern polar region – the International Lunar Research Station (ILRS). While the details are still scant, periodic updates have provided a “big-picture” idea of what this lunar outpost will look like.

Case in point, at a recent national space conference, a team of scientists from the Chinese Academy of Sciences (CAS) presented a list of objectives for the ILRS. According to China Science Daily, these objectives will include Moon-based astronomy, Earth observation, and lunar in-situ resource utilization (ISRU). In addition, the CAS scientists indicated that China plans to establish a basic model for a lunar research station based on two planned exploration missions by 2028, which will subsequently expand into an international base.

For years, China has been dropping hints about its Long March 9 (CZ-9) rocket, a three-stage super-heavy variant of the Long March family. This launch vehicle will reportedly be capable of transporting up to 150,000 kg (165 tons) to Low Earth Orbit (LEO) and 54,000 kg (59.5 tons) to a trans-lunar injection. On March 2nd, the China Academy of Launch Vehicle Technology (CALT) announced (via the Chinese social media platform Weixin) that it had finished building the first propellant tank for the CZ-9.

The news was accompanied by pictures that showed the finished tank and the many components that went into making it – and they are massive!

China’s National Space Administration (CNSA) has been hoping to reestablish communications with the Zhurong Mars rover, but so far, their efforts have been unsuccessful. Zhurong was put into hibernation over six months ago as it hunkered down in attempts to survive the Martian winter.
