An update on the Xuntian space telescope:
– Tests of the main optical system have been completed, and it meets all design requirements
– The integration of the multi-channel imager, integral field spectrometer, and terahertz module with the main optical system has been completed
– The survey camera and coronagraph are being integrated.

China has officially opened the application process to international participants to send payloads with the Tianwen-3 Mars sample return mission. The total available payload capacity is 20kg, with 15kg to be carried by the orbiter and 5kg by the service module. The Tianwen-3 mission is set to launch around 2028.

According to Mr. Bu Xiangwei (布向伟), co-CEO of OrienSpace, the Gravity-2 launch vehicle is in active design phase. It's on track for maiden launch by the end of 2025 to early 2026. Commercial reusability will be achieved in 2029, with an initial launch cost of ¥20,000/kg. Mr. Bu expects launch cost will be further reduced to less than ¥10,000/kg after production optimizations and scale-up.

(寰宇航天) is building a commercial liquid engine test center in Xintai, Shandong. The center will have three engine testbeds (30-ton class, 100-ton class, and 1000-ton class) that can accommodate both LOX/kerosene and LOX/methane propellant combinations.

SHANGHAI, April 24 -- The China National Space Administration (CNSA) announced on Thursday that scientists from institutions in France, Germany, Japan, Pakistan, the United Kingdom (UK) and the United States (U.S.) have been granted the opportunity to borrow lunar samples collected by the Chang'e-5 mission for scientific research.

At a ceremony for China's Space Day in Shanghai, the agency announced that seven institutions from six countries have been authorized to borrow the lunar samples.

The authorized institutions include the Institut de Physique du Globe de Paris (IPGP) in France, the University of Cologne in Germany, Osaka University in Japan, the Pakistan Space and Upper Atmosphere Research Commission (SUPARCO), the Open University in the UK, Brown University in the US, and the State University of New York at Stony Brook in the US.

In 2020, China's Chang'e-5 mission retrieved samples from the moon weighing about 1,731 grams.

Shan Zhongde, head of the CNSA, said China's lunar exploration program has always adhered to the principles of equality, mutual benefits, peaceful utilization and win-win cooperation, sharing achievements with the international community.

He added that CNSA will continue to accept international applications for lunar sample research, expressing hope that global scientists will make new discoveries that expand human knowledge and benefit humanity.

In November 2023, CNSA opened applications for international researchers to borrow Chang'e-5 lunar samples. By the end of December 2023, it had received 24 applications from 11 countries and international organizations.

published recently:
– Launch Chang'e-7 in 2026, composed of a lunar orbiter, lander, rover, and a small flying probe to explore the resources of the lunar South Pole.
– Launch Chang'e-8 in 2028 to test in-situ resource utilization and 3D-printing construction technology to prepare for manned lunar exploration.
– The first manned lunar landing in 2029-2030, using two Long March 10 launches to send two astronauts to the lunar surface.
– Build an international lunar scientific research station from 2035 to 2045, establishing a long-term base on the Moon to conduct scientific research and technology verification.

A few slides on the upcoming Chang'e-8 mission (planned for 2028). One of the rovers appears to have a humanoid robot mounted on top, not sure if that's actually the case. Of further interest, some 200kg of payload capacity is reserved for equipment from international partners, the selection process for which is almost finished. It's expected that some 10 foreign partners will be chosen. Finally, the lander now features a crane for deploying the rovers and other equipment such as seismometer onto the lunar surface. The crane eliminates the need for separate deployment mechanisms for these payloads.
