US Space Force Launches STP-H10 Mission, Delivers Six Experimental Payloads to ISS
April 29, 2025
The STP team was responsible for designing the payload infrastructure and ensuring seamless operation with the ISS systems.
The STP plays a crucial role in advancing space technology by providing rapid access to space for research and development.
Lt. Col. Brian Shimek, Director of the DoD Space Test Program, highlighted the mission's importance in exploring new technologies in space and its contribution to future Space Force capabilities.
The U.S. Space Force successfully launched the Space Test Program-Houston 10 (STP-H10) mission on April 21, 2025, delivering six experimental payloads to the International Space Station (ISS).
This launch was a collaboration between the Space Force's Space Systems Command and NASA, utilizing SpaceX's Commercial Resupply Service (CRS)-32 mission.
Space Systems Command manages a $15.6 billion budget aimed at enhancing U.S. strategic advantages in space, working with various organizations to tackle emerging threats.
The STP-H10 mission is a collaborative effort involving multiple agencies, including NASA, the U.S. Naval Research Laboratory, the U.S. Air Force Academy, and the Missile Defense Agency.
The payloads were robotically mounted onto the European Space Agency's Columbus module for a one-year operational period.
Key experiments included the Neutron Radiation Detection Instrument - 1B (NeRDI-1B) for neutron detection, Falcon Optical Defense and Intelligence through Neuromorphics (Falcon ODIN) to study lightning physics, and the Cadmium Zinc Telluride Radiation Imager (TERI) for radiation detection qualification.
Falcon ODIN, developed by the U.S. Air Force Academy, is designed to capture high-speed images of atmospheric phenomena.
Other significant experiments include the Space Edge Experiments and Demonstrations (SEED) for real-time data processing, the Space Plasma Diagnostic Suite 3 (SPADE-3) for monitoring space weather, and the Solar Flare X-Ray Timing Investigation (SFXTI) to analyze solar flare dynamics.
The launch took place at 4:15 am EDT from Launch Complex 39A at Kennedy Space Center, Florida.
