ISS Science for Everyone

Science Objectives for Everyone
The Materials on International Space Station Experiment - 8 (MISSE-8) tests various materials and computing elements on the exterior of the space station. The payload container is mounted so one side faces the Earth and the other faces space. The harsh environment of low-Earth orbit exposes the materials to a vacuum, atomic oxygen, ultraviolet radiation, direct sunlight and extreme heat and cold. The experiments provide a better understanding of material durability, from coatings to electronic sensors, which could be applied to future spacecraft designs.

    Previous ISS Missions
    NASA has conducted a series of space experiments to determine the best materials to survive in the space environment on Shuttle and Mir. MISSE-1 and 2 were delivered to ISS on STS-105 in August 2001 and returned on STS-114 in August 2005. MISSE-5 was deployed during STS-114 in August 2005 and returned on STS-115 in September 2006. MISSE-3 and 4 were delivered to ISS on STS-121 in July 2006 and returned on STS-118 in August 2007. MISSE-6A and 6B were delivered to the ISS on STS-123 in March 2008 and returned on STS-128 in September 2009. MISSE-7A and 7B were delivered to the ISS on STS-129 in November 2009, and were returned on STS-134 in May 2011.

    Experiment Description

    Research Overview

    • The Materials on International Space Station Experiment - 8 (MISSE-8) assess impacts of the space environment (vacuum, solar radiation, atomic oxygen, micrometeorites and thermal cycling, etc.) on materials and processor elements.


    • Specimens include advanced solar cells, spacecraft materials, and lightweight computing devices and techniques, which will be tested during long-term exposure to the space environment.


    • Science data is downlinked via ISS communication link. Sample return will occur inside the SapceX Dragon capsule as part of the SpX-5 mission.

    Description

    The Materials on International Space Station Experiment - 8 (MISSE-8) is a suite of experiments that includes new and affordable materials and computing elements. The samples tested have potential use in advanced reusable launch systems and advanced spacecraft systems including solar cells, optics, sensors, electronics, power, coatings, structural materials and protection for the next generation of spacecraft. The development of the next generation of materials and computing technologies is essential to the mission of traveling beyond Earth’s orbit.

    The samples are installed in holders and placed in experiment trays within a Payload Experiment Container (PEC). MISSE-8 consists of one new PEC, as well as a smaller experiment called the Optical Reflector Materials Experiment III Ram/Wake (ORMatE-III R/W). The MISSE-8 PEC and ORMatE-III R/W both reuse the MISSE-7 mounting interface and power/data system infrastructure on the MISSE-7 ExPRESS Pallet Adapter (ExPA), which was previously integrated to the ISS on the ExPRESS Logistics Carrier 2 (ELC-2) during the STS-129 mission. The orientation of the MISSE-8 PEC is zenith/nadir (space facing/Earth facing), and ORMatE-III R/W is ram/wake. MISSE-8 is the third experiment in the MISSE program to receive power directly from the ISS, and the second to use uplink/downlink capabilities on the ISS communication system to receive commands and downlink data.

    Applications

    Space Applications

    Many of the materials and sensors tested in the MISSE experiments could be incorporated into new spacecraft designs. Advanced materials tested with MISSE could also  improve the performance of satellites, solar cells and other space-based technology. Missions on other planets have already benefitted from MISSE research:  a static-dissipating paint tested in a previous MISSE experiment now coats components of NASA’s Curiosity Mars rover.
     

    Earth Applications

    Ultraviolet radiation, oxidization and other phenomena happen on Earth as well as in space. Research on atomic oxygen oxidation could improve designs of fire-retardant and rust-resistant material on Earth. Interactions between various materials and solar ultraviolet radiation could improve terrestrial structures, such as plastic siding for houses. In addition, the MISSE experiments could lead to better protective designs for communications and weather satellites.

    Operations

    Operational Requirements

    MISSE-8 will operate on the ExPRESS Logistics Carrier 2 (ELC-2), which will be located on the S3 Truss Outboard Zenith site. MISSE-8 will reuse the mounting and power/data infrastructure on the MISSE-7 ExPRESS Pallet Adapter (ExPA). It requires power and data provided by the Station, but does not require crew interaction, other than at deployment and possibly retrieval. The critical interaction is between the samples and the space environment.

    Operational Protocols

    During extravehicular activity, astronauts installed the MISSE-8 PEC on the ISS during STS-134, and will install ORMatE-III R/W on the ISS during STS-135. During EVAs throughout the deployment of MISSE-8, crewmembers will capture snapshots of the PEC, if time permits. The MISSE-8 PEC and ORMatE-III R/W will be retrieved via EVA for return inside the SpaceX Dragon capsule as part of the SpX-5 mission.
