The IAC 2023 Call for Abstracts and Special Sessions is now open!


The goal of these Special Sessions is to provide a forum for focused discussions on new technical and multidisciplinary topics and provide opportunities for audience engagement. Special Session will be mainly evaluated on the following criteria:

  • Special Sessions must be participatory and shall propose an interactive format such as fishbowls, campfires, design sprints, workshops etc. Opportunities for audience participation in the discussion must be demonstrated. Standard formats such as panels will not be considered.
  • Special Sessions must be multidisciplinary and demonstrate transversal aspects, as well as cutting-edge Special Session proposals must be submitted online at by 10 February 2023 (23:59 CET).

Should you have any questions concerning the Special Sessions, please contact the IAF Secretariat at


The Call for Abstracts is a precursor to a subsequent submission of a final paper, which may be presented at the 74th IAC. Authors are invited to submit an abstract regarding an original, unpublished paper that has not been submitted in any other forum. Papers can be submitted for either formal oral presentation or interactive presentation. The list with the Technical Sessions can be found here:
All selected papers will be treated as equally important in the presentation sessions and Congress Proceedings, differing only in the format of the presentation sessions (in other words, Oral Presentation papers will NOT be considered more important than Interactive Presentation papers). Abstracts shall be submitted through by 28 February 2023 (23:59 CET) and shall fit into one of the following IAC categories:

  • Science and Exploration – Systems sustaining missions, including life, microgravity, space exploration, space debris and Search for Extra-Terrestrial Intelligence (SETI).
  • Applications and Operations – On-going and future operational applications, including earth observation, communication, navigation, human space endeavors and small satellites.
  • Technology – Common technologies to space systems including astrodynamics, structures, power and propulsion.
  • Infrastructure – Systems sustaining space missions including space system transportation, future systems and safety.
  • Space and Society – Interaction of space with society including education, policy and economics, history and law, space security and sustainability, space arts, planetary defense and NEO.
