In the case of over-subscription\, we will maintain a back-up list of registrations. \n  \nProgramme overview\n3rd Zero Debris Future Symposium | September 8-9\nJoin the third edition of the Zero Debris Future Symposium for high-level discussions on the non-technical aspects of the Zero Debris initiative\, including: \nStructuring the Zero Debris Community for Enhanced Impact\nBeyond and after Zero Debris: What Role for the Community?\nThe inaugural workshops of the first Policy Working Groups\nStart time: 13:30 on 08/09/26\nEnd time: 12:30 on 09/09/26 \nZero Debris Technical Sessions | September 9-11\nJoin us for a new series of technical sessions dedicated to advancing the Zero Debris initiative. Participants will review the outcomes of the mapping and prioritisation tasks for the Booklet and share pitches highlighting cutting-edge technologies. There will also be two focused working sessions: one on technical White Papers and another on the development of a shared database of technologies supporting the Zero Debris effort. \nA dedicated training session on outreach and expanding the international reach of the ZD Booklet will help strengthen engagement across the community. \nThe Technical Sessions will conclude with B2B meetings\, offering participants the opportunity to connect\, exchange perspectives\, and explore new collaborations. \nStart time: 14:00 on 09/09/26\nEnd time: 13:00 on 11/09/26 \nLimited Places Available\nWe invite organizations to coordinate and send a limited number of representatives who can actively contribute to shaping the future of space sustainability. Your expertise and input are invaluable to achieving our zero debris goals by 2030. \nIn the case of over-subscription\, ESA will strive to invite a diversity of organisations to participate in the ZD Week. ESA reserves the right to prioritise attendance based on previous involvement in the ZD Charter and the ZD Technical Booklet.

SUMMARY:The Space Policy Forum: Bringing Space to the National Debate
DESCRIPTION:The Aerospace Corporation’s Center for Space Policy and Strategy presents the inaugural Space Policy Forum – bridging the gap between the space sector and the broader policy community. \nAs space becomes increasingly central to national security\, economic competitiveness\, and international leadership\, decisions made in one domain ripple across others. Launch regulations impact commercial aviation.  Industrial policy decisions in space reverberate across the broader economy. Geopolitics are reshaping international partnerships and alliances. \nThrough dynamic panels\, impactful debates\, and targeted breakout sessions\, explore how space policy intersects with—and influences—broader national priorities. \nJoin us on September 2\, 2026\, in Washington\, DC\, to forge a more integrated approach to space and national policy. \nPanels: \n\nIndustrial Policy: How Aggressive Should We Be With Space\nWhat Does U.S. Leadership in Space Exploration Mean\nQuick on the Draw: Debate on Whether the U.S. Should Seek to Avoid or Embrace Space War\nFuture of International Space Partnerships\nA Market Opportunity: Investing in Space\nThe Launch Crunch: Space Constrained Airspace

SUMMARY:Launch Falcon Heavy / Nancy Grace Roman Space Telescope
DESCRIPTION:Launch set for 0:26 EDT | Roman spacecraft is 12.7 meters long and 4.4 meters wide when fully deployed. Its primary mirror is 2.4 meters in diameter\, which is the same size as the Hubble Space Telescope’s primary mirror. It will have sensitivity and resolution comparable to Hubble\, but a field of view 100 times larger\, combining excellent image quality with survey power. And it weighs 80% less than Hubble’s primary mirror\, showcasing an advancement in telescope technology.
