IAC 2025 Call for Abstracts Results
Nearly 6400 abstracts from 103 countries!

The global interest in space is reaching new heights as the upcoming 76th International Astronautical Congress in Sydney builds on the remarkable success of last year’s event in Milan. Following an impressive 7,000 abstracts from 106 countries, this year’s submissions are equally spectacular, with nearly 6,400 abstracts from 103 countries set to fuel discussions and innovations in the space sector.
This year, Australia, our host country for IAC 2025, has made a significant mark with 505 abstracts submitted, accounting for 8% of the total contributions. This vibrant participation underscores the global space community’s commitment to advancing space exploration and technology.
The space sector has solidified its position once again as a pivotal topic on the global agenda, riding a wave of enthusiasm that began at IAC 2022 in Paris with an incredible 3,558 abstracts from 97 countries.
We are excited to welcome new contributors from Kiribati and Brunei Darussalam, further expanding our community’s frontiers.
Leading the charge in submissions are:
- United States: 724 abstracts
- Azerbaijan: 632 abstracts
- India: 565 abstracts
Italy, last year's IAC host, remains strong with 391 abstracts, followed by Germany (299), Japan (273), UK (241), and a surprising entry from Mexico (183), which previously hosted the IAC in 2016.
These impressive figures reflect the immense interest in our Congress and the inspiring congress theme of "Sustainable Space : Resilient Earth." This theme will guide our discussions on the critical need for collaboration across all regions, connecting the global space community to ensure a sustainable future for Earth and beyond.
As momentum continues to build for Sydney, we look forward to engaging with thought leaders, researchers, and enthusiasts who are pushing the boundaries of what is possible in space.
