The STP-H9 (Space Test Program - Houston 9) is a combo of experiments to be hosted on the International Space Station (ISS).

STP-H9 includes following experiments:

  • The Space Wireless Energy Laser Link (SWELL) laser power beaming demonstration experiment by the Naval Research Laboratory will attempt to establish an optical power beaming link between laser transmitters and receivers packaged inside a 1.7-meter tube. The experiment is a step forward in laser power beaming technology, which transmits energy in the form of electromagnetic waves without transferring mass.
  • An Electric Propulsion Electrostatic Analyzer from the Air Force Academy
  • a Neutron Radiation Detection Instrument from NRL
  • a Variable Voltage Ion Protection Experiment from NRL
  • The Experiment for Characterizing the Lower Ionosphere and Production of Sporadic-E, or ECLIPSE, is another NRL experiment that will measure conditions in the ionosphere, a layer of the upper atmosphere where solar radiation can disrupt radio communications.
  • The Glowbug instrument, also managed by NRL with NASA support, is a miniature gamma-ray telescope designed to detect cosmic rays emitted by super-energetic explosions called gamma-ray bursts in the distant universe. Glowbug will also try to detect mysterious gamma-ray emissions from thunderstorms on Earth.
  • N
  • ASA's Goddard Space Flight Center's SpaceCube Edge Node Intelligent Collaboration, in collaboration with the Air Force Research Laboratory and Aerospace Corp., will evaluate artificial intelligence and machine learning technology using AI microchips.
  • In addition, the Stellar Occultation Hypertemporal Imaging Payload experiment from Lawrence Livermore National Laboratory will put to the test a high-resolution, high-frame-rate camera that could be used on future space missions to measure atmospheric temperature profiles by observing how the air refracts light from a star passing through the atmosphere.

The STP-H9 package will be launched as an external payload on the Dragon CRS-27 cargo spacecraft.
