The mission, scheduled for launch aboard Momentus’ Vigoride orbital service vehicle in late 2026, will provide Pulsar with a critical in-orbit testing opportunity for its HET propulsion system—designed to deliver high-efficiency thrust for next-generation spacecraft. This collaboration marks a significant milestone in the commercialization of advanced electric propulsion systems and highlights the growing demand for flexible, cost-effective space testing platforms.
“We’re thrilled to support Pulsar’s journey to develop next generation technology,” said John Rood, CEO of Momentus. “Our Vigoride orbital service vehicle is designed to accelerate innovation by providing reliable access to space for emerging technologies. Pulsar’s HET system represents a leap forward in sustainable propulsion, and we’re proud to help bring it to orbit.”
Pulsar’s Hall Effect Thruster is engineered for high specific impulse and long-duration missions, making it ideal for satellite station-keeping, orbital transfers, and deep space exploration. The demo mission will validate key performance metrics in the space environment, including thrust efficiency, thermal stability, and electromagnetic compatibility.
The demonstration aligns with both companies’ commitment to advancing sustainable and scalable space infrastructure. By enabling in-orbit testing, Momentus continues to support the rapid iteration of space technologies that will shape the future of satellite operations and interplanetary missions.
