The IAF Newsletter - May 2026 Edition
Dear IAF Friends,
As we move further into another exciting year for the global space community, I am pleased to welcome you to the May 2026 edition of the IAF Newsletter. This year holds particular significance for the International Astronautical Federation (IAF) as we celebrate its 75th anniversary, a remarkable milestone reflecting decades of commitment to advancing space science, technology, and international cooperation.
Following the dynamic and fruitful discussions at the IAF Spring Meetings in Paris, we are now fully focused on the organization of two major upcoming events: 77th International Astronautical Congress (IAC 2026) in Antalya, Türkiye, to be held from 5-9 October, the celebration of the 75th anniversary of the IAF, planned for 28 November, in Paris, France and next year’s 78th International Astronautical Congress (IAC 2027) in Poznań, Poland.
A quick but important update for GLOC 2026 attendees: on behalf of the IAF, and in close contact with our colleagues at the Rwanda Space Agency (RSA), we must share that GLOC 2026 in Kigali, scheduled for 2-4 June, has been postponed until further notice. This was not an easy decision, but participant well-being and health considerations always must lead the way. I know many of you were looking forward to meaningful sessions and in-person collaborations in Rwanda. The IAF remains deeply committed to engaging with our host and stakeholders, and we will communicate new plans as soon as they take form.
Looking ahead to the 77th International Astronautical Congress (IAC 2026) to be held from 5–9 October, we are especially encouraged by the remarkable response to the call for abstracts. A record of 8,325 abstracts from 108 countries have been received, setting a new benchmark for the IAC, and 4,619 abstracts have been selected in the programme, comprising 4077 accepted and 542 strong back-ups. This exceptional participation underscores the strength, diversity, and global reach of our community.
Our upcoming events showcase the energy and dynamism of our Federation, as well as our collective determination to advance space for the benefit of humanity. They also highlight the value of collaboration across borders, disciplines, and generations as we tackle shared challenges and pursue new opportunities.
I extend my sincere thanks to everyone contributing to the success of our events, and I look forward to welcoming many of you in Antalya in the coming months.
Sincerely,
Gabriella Arrigo,
IAF President
