The STP-S30 mission will deploy the first DiskSats to space: a disk-shaped spacecraft platform developed by The Aerospace Corporation (Aerospace) and funded by NASA that offers an alternative approach to small satellites. Electron will deliver the constellation of four DiskSats to a 550km low Earth orbit where Aerospace will test their maneuverability, launch dispenser mechanism and orbit-changing capabilities using electric propulsion - key features in flexible, responsive space operations. ‘Don’t Be Such A Square will be Electron’s 20th launch of the year and 78th mission overall.
