STP-S29A is a mission under the U.S. Department of Defense's Space Test Program (STP) that will deliver technology demonstrations to orbit and contribute to future space system development, with this launch delivering up to 200 kg of STP cubesats to Low Earth Orbit. The main payload will be STPSat-7, an ESPA class satellite based on the Aegis Aerospace M-1 satellite bus used on the STPSat-4 mission for hosting research and technology demonstration payloads for the Department of Defense (DoD). One of the payload is U.S. Naval Research Laboratory's (NRL) Lightsheet Anomaly Resolution and Debris Observation (LARADO) instrument, used to detect and characterize lethal non-trackable orbital debris with lasers in orbit.
