A recent Rocket Lab Electron launch from Virginia carried four small satellites into orbit, marking the beginning of a government-funded mission to evaluate a novel spacecraft design. These satellites, deployed from a cylindrical dispenser atop the Electron rocket, represent a “proof of concept” for DiskSats. These are the flying discs the government wants you to know about, a new type of satellite developed by the Aerospace Corporation, a federally funded research and development center. The project is a collaborative effort between NASA and the US Space Force, with the latter financing the DiskSat’s development and launch.

Background Context
The Aerospace Corporation, established in 1960, has a long history of supporting the US military and NASA. The DiskSat concept emerged from a survey of the government’s evolving needs in spaceflight. For nearly a quarter-century, CubeSats, based on a cube-shaped design, have become a standard in the satellite industry. These are the flying discs the government wants you to know about, an alternative to the ubiquitous CubeSat. The CubeSat standard has been adopted by commercial companies, the military, NASA, and universities for building small satellites on a budget. Since 2003, nearly 3,000 CubeSats have been launched, reaching various orbits, including the Moon and Mars.
While CubeSats have become widespread, engineers at the Aerospace Corporation identified opportunities for improvement. The DiskSat design, conceived by Rich Welle, addresses the need for alternative form factors that could generate more power and offer benefits for specific mission applications. These are the flying discs the government wants you to know about, a novel solution to challenges faced by traditional satellite designs.
The DiskSat Design and Advantages
The DiskSat design is a stackable, flat-panel format that is easier to pack for launch compared to CubeSats. This concept mirrors SpaceX’s approach to launching Starlink satellites, but DiskSats are smaller, lighter, and adaptable to various missions. These are the flying discs the government wants you to know about, a new design that emphasizes maximizing surface area.
DiskSats offer several advantages over CubeSats. Each DiskSat weighs approximately 35 pounds (16 kilograms), lighter than a typical 12U CubeSat. However, a DiskSat has over 13 times the surface area on a single side, providing ample space for solar arrays, sensors, antennas, and other payloads that cannot fit on a CubeSat. These are the flying discs the government wants you to know about, offering more space for critical components. The DiskSat design offers a power-to-weight ratio that surpasses traditional aluminum satellites. Research indicates that DiskSat can generate five to ten times more power than a CubeSat.
Potential Missions and Disruptive Applications
The Aerospace Corporation envisions DiskSats being used in various missions, including weather forecasting, Earth observation, and communications. The increased surface area allows for deploying larger and more powerful sensors for improved data collection. These are the flying discs the government wants you to know about, a design that could potentially disrupt existing satellite technology.
The stackable nature of DiskSats also enables the deployment of multiple satellites in a single launch, reducing costs and increasing efficiency. This could lead to the development of more complex and capable satellite constellations. These are the flying discs the government wants you to know about, offering a cost-effective solution for deploying satellite networks.
Future Outlook for DiskSat Technology
The successful launch and initial contact with all four DiskSats represent a significant milestone in the development of this new satellite technology. The ongoing demonstration mission will further validate the viability and performance of the DiskSat design. These are the flying discs the government wants you to know about, and their future looks promising.
The potential applications of DiskSats are vast, and their unique design offers several advantages over existing satellite technologies. As the technology matures, DiskSats could play a crucial role in various space missions, contributing to advancements in weather forecasting, Earth observation, and communications. These are the flying discs the government wants you to know about; they could revolutionize the future of space exploration and satellite technology.
