Impulse Space will use the upgraded Mira on LEO missions as well, with its first mission slated to launch in late 2025. Among the customers for Mira is in-space refueling company Orbit Fab, which will host a fuel depot on a Mira vehicle in 2026 as part of a mission to refuel the U.S. Space Force’s Tetra-5 satellite in GEO.
As it rolls out the upgraded Mira vehicle, Impulse Space is moving into development of Helios, including preparing to begin tests of the powerpack for the engine that will power the stage as well as working on tanks for the vehicle. Helios will also reuse avionics created for Mira.
“Last year was mostly about Mira and getting that LEO Express 1 mission up,” Mueller said. “This year is mostly about Helios.”
