STP-S30 is a complex mission that will deliver research experiments and technology demonstrations to orbit for the DoD and contribute to future space systems development. The projected primary payload, DISKSat, will demonstrate sustained very low earth orbit (VLEO) flight and test a unique, 1-meter diameter, disk-shaped satellite bus that is designed to increase on-orbit persistence.
Events will appear closer to launch. Expected:
