Attention all teams! Due to current supply and demand, ESRA will be providing a limited number of student tents this year. We strongly recommend that teams bring their own tents to ensure their needs are met. Prepare for IREC as you would for certification and test launches to ensure a smooth experience at the event.

Introducing Sovereignty! 🏇 🚀 In just one month, our rocket will be competing in the 2026 International Rocket Engineering Competition under the 10k COTS Solids category. After months of designing and testing, we’re excited to finally see our rocket take flight on the national stage alongside collegiate teams from around the world! Every component of Sovereignty represents the dedication and hard work of our team members, from the creation and development of our student-designed Z-Axis Control (Z.A.C.) system to our development of the dual bay dual deploy recovery approach! 🛠️ Stay tuned for more content of our work and behind-the-scenes posts in the next few weeks! #rocketry #engineering #aerospace #irec2026 #uofl @esra.rocket
