Experimental Sounding Rocket Association

ESRA looks forward to working with you over the next 8 months! HeroX, as well as soundingrocket.org website and our social media sites will all celebrate this announcement. Trust that ESRA is WORKING VERY HARD on our new launch site. We will announce this as soon as we can. Multiple sites are still being evaluated. For teams who were declined, it is highly recommended that you seek other opportunities to compete and/or launch in your region, in preparation for the 2026 IREC. Typically, application are declined for one or more of the following reasons: - Poor overall quality of the application, lacking detail, incorrect or missing data - Team lacked sufficient experience to safely design, build and launch a rocket in that specific category - Team did not follow rules and regulations or standards set forth in the DTEG - Flyer of Record not provided or was not Tripoli L3 certified The number of international collegiate rocketry competitions and teams continues to grow. Latin America, Australia, Canada, Europe, Turkey, Algeria, Peru, Portugal, Korea, Nepal, Mexico etc. have grown in both experience and expertise with enhanced applications for the 2025 IREC. In the US, teams should look to compete in the Argonia Cup or any of the great events at the Friends of Amateur Rocketry (FAR) site in southern California. For those teams who will be competing this year, ESRA is working hard to make this not only the largest, but the best event ever held. Over the next few weeks, there will be many updates and requests to student team leaders. Please respond to these as quickly as possible to ensure your team is 100% prepared. For international teams seeking a formal acceptance letters, please send a request to [email protected] June is only a short 8 months away. Get busy with your designing, building and testing! -The ESRA Team
