Comet is going (back) to space

calendar icon April 14, 2025
At Comet, we believe progress starts with curiosity – and few frontiers spark it like space. That’s why we’re partnering with Project HERMES as a sponsor – supporting the student team at ARIS to build and launch a bi-liquid propulsion rocket at the European Rocketry Challenge (EuRoC) in 2025. If successful, it will be the first Swiss rocket of its kind to reach an altitude of 8000 m – a major milestone for student aerospace in Switzerland. From cryogenic propellants to guided recovery, HERMES is a showcase of what happens when curiosity meets collaboration. Just like in our own work, their success depends on precision, teamwork, and a drive to go beyond – values we share as they reach for the skies.
