The STPSat-6 payloads including the Space and Atmospheric Burst Reporting System 3 (SABRS-3), a functional objective from the National Nuclear Security Administration, NASAs Laser Communication Relay Demonstration (LCRD) payload to check technologies for the next generation of information relay satellites, and numerous Department of Defense Space Experiments Review Board space weather condition and situational awareness payloads.
The launch was postponed one day due to a leakage in a ground propellant system for the rockets RP-1 fuel.The Atlas V rocket will introduce the STP-3 objective for the U.S. Space Force from Space Launch Complex 41 of the Cape Canaveral Space Force Station in Florida. (Image credit: United Launch Alliance) Mission OverviewA United Launch Alliance (ULA) Atlas V 551 rocket will launch the Space Test Program-3 (STP-3) objective for the U.S. Space Forces (USSF) Space Systems Command (SSC). STP-3 is a co-manifested mission that develops technology and minimizes future space program risk for the Department of the Air Force and the U.S. Space Force by advancing warfighting abilities in the areas of nuclear detonation detection, space domain awareness (SDA), weather condition, and interaction. Liftoff will take place from Space Launch Complex-41 at Cape Canaveral Space Force Station, Florida.The primary spacecraft is STP Satellite (STPSat) -6 and the rideshare spacecraft is the Long Duration Propulsive Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter (ESPA) (LDPE) – 1. The STPSat-6 payloads consisting of the Space and Atmospheric Burst Reporting System 3 (SABRS-3), a functional mission from the National Nuclear Security Administration, NASAs Laser Communication Relay Demonstration (LCRD) payload to evaluate technologies for the next generation of data relay satellites, and several Department of Defense Space Experiments Review Board space weather and situational awareness payloads.
