Hermes Static Fire Test

Since its inception, continuous efforts towards manufacturing the nozzle and cooking ideal grains culminated in a successful static fire in May 2024. On May 25, 2024, RPL's Hermes team completed the organization's first static fire of an experimental solid rocket motor. Due to the hard work of the Hermes team, the static fire was a complete success, and we're excited to be making our way towards launch as we continue marking off the checklist of test procedures.
