STP-H4

STP-H4 [NRL]

The STP-H4 (Space Test Program - Houston 4) is a combo of experiments to be hosted on the International Space Station (ISS).

Following experiments are mounted on STP-H4:

  • SWATS (Small Wind And Temperature Spectrometer) (NRL) acquires simultaneous co-located, in-situ measurements of atmospheric density,
  • iMESA-R (Integrated Miniaturized Electrostatic Analyzer-Reflight, USAFA) is integrated into SWATS, enabling synergistic co-located density and temperature measurements between the instruments
  • GLADIS (Global Awareness Data-Exfiltration International Satellite Constellation Concept) (NRL) will demonstrate co-channel interference mitigation (antenna design) by receiving the Automatic Identification System (AIS) vessel tracking signal while simultaneously providing two way communications to widely distributed Maritime Domain Awareness sensor arrays
  • MARS (Miniature Array of Radiation Sensors) (NRL) consists of an array of sensors that monitor the total dose radiation on the host spacecraft for 3-D radiation modeling NASA JSC is a co-investigator on MARS, and the MARS experiment includes NASA JSC provided radiation shielding on some of the MARS sensors
  • ATT (Active Thermal Tile) (AFRL) is a quick-insert thermal control device that is modular, reconfigurable, and fully scalable to a wide array of component sizes
  • ISE 2.0 (ISS SpaceCube Experiment 2.0) (NASA GSFC) consists of three experiments:
    • SpaceCube 2.0: A small, powerful data processing module with multiple HD cameras to demonstrate new algorithms, including “Radiation Hardened By Software” algorithms and Earth “event detection” algorithms
    • EHD: A thermal plate prototype to demonstrate Electro Hydro-Dynamic (EHD) pumping of liquids in microchannels for advanced thermal control
    • FireStation: Measures the optical lightning flash, the radio signatures of lightning, and the gamma rays and electrons produced in terrestrial gamma ray flashes

The STP-H4 package was launched as an external payload in HTV 4 (Kounotori 4). STP-H4 was installed on ELC-1.
