STP-H6 [DoD]

The STP-H6 (Space Test Program - Houston 6) is a combo of experiments to be hosted on the International Space Station (ISS).

STP-H6 will carry eight SERB experiments, including experiments related to star tracker and communications technology and space environment monitoring.

STP-H6 includes following experiments (not complete):

  • XCOM is an x-ray communication investigation that will be used to perform a space-based demonstration of a new technology for generating beams of modulated x-rays, to be received by NICER, also mounted on the ISS. This technology may be useful for providing efficient communication to deep space probes, or communicating with hypersonic vehicles where plasma sheaths prevent traditional radio communications.
  • iMESA electrostatic analyser for ionospheric studies, USAF Academy
  • SSIVP supercomputing for image and video processing, with dual Earth imaging cameras, from the University of Pittsburgh
  • Plasma impedance probe, NRL
  • ACES-RED-1, an US Army SMDC package with student-built experiments for future Army cubesat technology including a GoPro and a Raspberry Pi

The STP-H6 package was launched in May 2019 as an external payload in the Dragon CRS-17 trunk. STP-H6 was installed on an ELC.

In November 2021, the STP-H6 packacge was disposed of by using the Cygnus CRS-16 freighter.
