A2. IAF MICROGRAVITY SCIENCES AND PROCESSES SYMPOSIUM
The objective of the Microgravity Science and Processes Symposium, organized by the International Astronautical Federation (IAF), is to highlight and discuss the state of the art in microgravity (reduced-gravity) physical sciences and processes, as well as to prepare for future orbital infrastructure. Session topics cover all microgravity science disciplines (material science, fluid physics, combustion science, fundamental physics), current results and research perspectives, together with relevant technology developments.

A2.6. Microgravity Sciences on board of Space stations
This session focusses on the presentation of scientific and operational results obtained from microgravity sciences research conducted on large orbital platforms, in particular the ISS, the Chinese Space Station (CSS) and upcoming commercial space stations. Papers on planned or newly developed research topics and experiment scenarios are also invited. The session is not limited to the usage of stations in low Earth orbits (LEO), but comprises the preparation scenarios for further long-term flight opportunities beyond low Earth orbits such as the Deep Space Gateway station.

A2.8. In-Space Manufacturing and Production Applications
In-space manufacturing represents an emerging capability that can revolutionize space exploration and utilization. Producing parts, tools, and even spacecraft in space eliminates the constraints and costs of launching every item from Earth. An IAC session would provide an important forum to share progress, innovations, and lessons learned. Speakers could highlight techniques like additive manufacturing with novel materials for spacecraft production and repair. Experts could also discuss biomanufacturing applications like tissue engineering and biomedicine production leveraging microgravity. Operators could share insights on managing material processing and fabrication off Earth. The symposium would connect leaders across disciplines tackling these technical challenges and catalyze innovations. As humanity expands into space, in-space manufacturing provides sustainability and cost benefits by enabling self-sufficiency. Terrestrially, it opens new avenues for manufacturing products impossible to produce in normal gravity. Commercial space companies are poised to benefit from reduced launch costs. As public and private entities target manufacturing in space, IAC participation would accelerate advances in this transformative field and maximize downstream applications on Earth.

A2.IP. Interactive Presentations - IAF MICROGRAVITY SCIENCES AND PROCESSES SYMPOSIUM
This session offers a unique opportunity to deliver your key messages in an interactive presentation on any of the subjects of Microgravity Sciences and Processes addressed in the classic Sessions. The presentation will be displayed on a digital screen in a dedicated location and available for view by all Congress attendees for the entire Congress week. In addition, one afternoon is dedicated exclusively for the attendees to view the Interactive Presentations, and the author will be assigned a specific ten minute slot to personally present the topic and interact with the attendees present. The Interactive Presentation may take advantage of all electronic display capabilities, such as: PowerPoint charts, embedded hot links, pictures, audio and video clips etc. An award will also be presented to the author of the best Interactive Presentation in the A Category at a special ceremony. An Abstract that follows the standard format must be submitted by the deadline for standard IAC abstracts.
