76th International Astronautical Congress Concludes

Chinese teams shared a wealth of information in Sydney.

The 76th International Astronautical Congress 2025 has concluded today in Sydney, Australia, wrapping up five days of technical sessions and presentations. During the congress, representatives for China’s space agencies and commercial sector participated in panels and held numerous technical talks.

Listed below are news items from the congress and some¹ papers discussed by those in attended. Many of the papers linked below currently only have their abstracts available for free, but some will end up being published in academic journals later on. Others are also available via the IAF directory.
