NASA’s DiskSat technology demonstration mission will test the performance of a new small spacecraft platform designed to expand the capabilities of current small spacecraft. By demonstrating the advantages of a flat, disk-shaped architecture over the conventional CubeSat design, DiskSat aims to enable lower-cost space missions, broaden scientific opportunities, and increase overall access to space.

At 12:03 a.m. EST on Thursday, Dec. 18, DiskSat launched aboard a Rocket Lab Electron rocket from the company’s Launch Complex 2 on Wallops Island, Virginia.

The demonstration will evaluate the performance of the

spacecraft themselves and a specialized dispenser mechanism. The dispenser is engineered to securely contain four DiskSat spacecraft during launch, then sequentially deploy them into low Earth orbit where they will perform maneuvers. Each DiskSat is a circular, flat spacecraft 40 inches (one meter) in diameter and one inch (two-and-a-half centimeters) thick – similar to a small coffee table. Each has an electric propulsion system to allow for orbit changes and maintenance. The DiskSat design is also conducive to operations in very low Earth orbit, which can offer sharper Earth imaging and sensing capabilities as well as lower latency communications solutions.

DiskSat boosts U.S. innovation and commercial space opportunities while providing mission designers new flexibility, enabling them to pursue and achieve NASA’s goals faster and more affordably. DiskSats offer an alternative platform that could significantly expand the scope of future small spacecraft missions for NASA, the commercial space industry, other government agencies, and academia. The DiskSat demonstration also supports NASA’s long-term plans for sustained exploration at the Moon and Mars as well as advancing our ability to study and better understand our home planet.

funded the development of the DiskSat technology and demonstration mission. The program is based at NASA’s Ames Research Center in California’s Silicon Valley. The DiskSat launch and in-orbit operations are funded by the U.S. Space Force’s Rocket Systems Launch Program (RSLP) and Department of War Space Test Program (STP), respectively. Rocket Lab USA, Inc., of Long Beach, California is providing launch services. NASA’s Wallops Flight Facility, the agency’s only owned and operated launch range, enabled the mission providing services such as tracking, telemetry, and range safety to ensure a safe and successful mission.
