In-Orbit Demonstration with SpaceX
SteamJet planned to perform the first in-orbit demonstration of a reliable, compact, and affordable water-based propulsion system launched from a Soyuz. However, this launch was delayed and later canceled. Therefore, our second planned demonstration, conducted with SpaceX, will now become the first in-orbit test.
SpaceX and Momentus have confirmed the launch, and SatRevolution has already prepared the SteamSat satellite for integration with our thruster. SteamJet has completed all necessary tests and collected all required documentation. The propulsion system is fully ready for launch.
The COVID-19 pandemic and limitations caused by it are not an obstacle to launch preparation. Once travel restrictions lift and borders reopen, our engineers will install the propulsion system. After installation, the SteamJet thruster will be transported to California for launch.
Upcoming In-Orbit Demonstrations and Commercial Partnerships
Additionally, SteamJet plans to conduct the second and third test in-orbit demonstrations of the water-based propulsion system on 3U – 6U satellites in 2021 that is why we are looking for commercial partners who would like to test their equipment in space on SteamSat satellites or install SteamJet TunaCan Thrusters on their satellite in 2021. If you would like to become our commercial partner, please contact us at sales@steamjet.space or +44 774 924-7736.
