DiskSat: NASA and the U.S. Space Force test pizza‑shaped smallsat bus for unmatched power‑to‑weight
DiskSat is a flat, disk‑shaped smallsat bus that proponents say offers a power‑to‑weight ratio unmatched by traditional aluminum spacecraft. NASA and the U.S. Space Force are testing the design to leverage higher electrical power and surface area for more capable payloads and experiments in low Earth orbit.
