What's Happening?
Viridian Space Corporation has been awarded a $1.7 million Phase II SBIR contract by the Department of Defense to develop air-breathing propulsion technology for satellites in very low Earth orbit (VLEO).
This technology uses atmospheric oxygen as fuel, allowing satellites to remain in VLEO longer and maneuver without traditional fuel constraints. The contract reflects the military's interest in leveraging VLEO for national security missions, offering advantages such as improved imaging and communication capabilities.
Why It's Important?
The development of air-breathing propulsion technology could revolutionize satellite operations in VLEO, providing significant strategic advantages for national security. By enabling satellites to maneuver freely and remain in orbit longer, this technology could enhance the U.S. military's ability to conduct surveillance and communication operations. The contract also underscores the growing importance of innovative propulsion solutions in maintaining technological superiority in space.
What's Next?
Under the AFWERX SBIR contract, Viridian will focus on assembling and testing the propulsion system on the ground over the next two years. The company plans to conduct partial space tests by 2027, with a full on-orbit demonstration to follow. Successful development could lead to broader adoption of air-breathing propulsion in both military and commercial satellite applications.
