Science Objectives for Everyone
Space Test Program-Houston 4-ISS SpaceCube Experiment 2.0 (STP-H4-ISE 2.0) demonstrates SpaceCube computing systems in low Earth orbit. The investigation uses software techniques to guard against radiation upsets, which can interfere with electronic devices. The hardware also includes a prototype of a thermal plate filled with micro-channels, which uses fluids to disperse and distribute heat, as well as an instrument (the STP-H4-FireStation) to measure gamma-ray flashes from lightning on Earth.

    Experiment Description

    Research Overview

    • Space Test Program-Houston 4-ISS SpaceCube Experiment 2.0  (STP-H4-ISE 2.0) is critical to enable “next generation” missions by providing the on-board computing power necessary to handle future ultra-high data rate instruments and advanced mission applications.

    • The successful demonstration of the STP-H4-ISE 2.0 experiment includes the processing of high definition Earth imagery and potentially unprecedented insight into the recently discovered phenomena of terrestrial gamma ray flashes.

    • The successful completion of the STP-H4-ISE 2.0 processing experiment will significantly increase the Technology Readiness Level of the system and significantly reduce the risk for future missions that wish to adopt this technology.

    • The successful completion of the STP-H4-ISE 2.0 gamma ray experiment may provide ground-breaking scientific discoveries in the fields of Heliophysics and Earth Science


    Space Test Program-Houston 4-ISS SpaceCube Experiment 2.0 (STP-H4-ISE 2.0) continues the development of Goddard Space Flight Center’s family of SpaceCube on-board science data processors.  The goal of the SpaceCube program is to provide 10x to 100x improvements in on-board computing power while lowering relative power consumption and cost. STP-H4-ISE 2.0coupled the SpaceCube 2.0 breadboard with a camera system, gamma ray detector, photometer, antenna and thermal plate experiment, with the primary goals of extending SpaceCube “radiation hardened by software” research, developing Earth Science “event detection” algorithms and studying gamma ray bursts from terrestrial lightening/thunderstorms.

    Space Applications

    STP-H4-ISE 2.0 demonstrates a new generation of processing and computing systems designed for use in low Earth orbit. Systems tested in STP-H4-ISE 2.0 may be used in a wide range of science instruments and Earth-observing missions. It will also be used as a test bed for new robotic servicing applications being developed by NASA.

    Earth Applications

    The investigation demonstrates next-generation space processors with 10 to 100 times more computing power than previous hardware. Advanced instruments will use this technology to enable the next generation of Earth science missions, collecting more data and intelligently using it to understand how Earth works. Future missions using STP-H4-ISE 2.0 components could improve weather and climate studies, as well as agriculture and natural disaster management.

    Operational Requirements

    This experiment requires a minimum of three operating months on-orbit, with a goal of 1-3 operating years on-orbit

    Operational Protocols

    STP-H4-ISE 2.0requires minimal interaction, and operates primarily in a “turn it on and let it run” mode.  Safety limits have been incorporated into the overall STP-H4 plan, and the ability to handle command and telemetry operations exists in the ISE 2.0 lab.
