ISS Science for Everyone

Science Objectives for Everyone The Technical Education Satellite (TechEdSat) investigation employs a small CubeSat spacecraft that will be deployed from the JEM-Small Satellite Orbital Deployer (J-SSOD) in order to evaluate, demonstrate and validate two new technologies. The first technology to be demonstrated is AAC Microtec’s plug-and-play electronics architecture, while the second demonstrates two different tracking and communication modules that utilize the Iridium and Orbcomm satellite phone networks. The primary goal of this investigation is to provide a rapid development demonstration for simplifying hardware and operations infrastructure for future spacecraft design and development.

    Experiment Description

    Research Overview

    • TechEdSat demonstrates two new technologies: the first being the Space Plug-and-Play Architecture (SPA) by AAC Microtec, which has the goal of rapidly advancing, reconfigured Nanosatellite technologies based on miniaturized avionics components; and the second, which utilizes two different tracking and communication modules.


    • TechEdSat is deployed using the JEM-Small Satellite Orbital Deployer (J-SSOD).


    • The rapid development CubeSat format intend to demonstrate subsystems which may reduce costs for Nanosatellite bus development, eliminate the need for physical ground station interfaces for Nanosatellites, and prove the reliability associated with ISS deployment.

    Description
    The Technical Education Satellite (TechEdSat) investigation launched aboard the H-II Transfer Vehicle (HTV) III mission and is to be deployed overboard from the JEM Small Satellite Orbital Deployer (J-SSOD) as capability that plays a key role to enhance the utilization of the ISS and the JEM. The primary goal of the TechEdSat investigation is to employ a small, CubeSat spacecraft to evaluate, demonstrate and validate two new technologies that are critical to the development of small satellites and future experiments.

    The first technology to be demonstrated is an AAC Microtec plug-and-play avionics architecture, which has the goal of rapidly developing, reconfigured Nanosatellite technologies based on miniaturized avionics components. In order to evaluate this technology San Jose State University students will develop, build, test and flight qualify a CubeSat for deployment from the International Space Station (ISS). Qualification and development of the CubeSat will be overseen by assigned NASA Ames mentors from the Chief Technology Office. The second goal is to demonstrate the use of two different tracking and communication modules with the small space satellite. These modules include a Quake Global Iridium 9602 transceiver and an ORBCOMM Q1000 modem, which utilize their respective satellite constellations for communication and tracking. These devices are held within in a 1 cube (1U; a 10x10x10 cm volume cube weighing roughly 1.3 kg) integrated hardware package that comprises a complete science experiment system. Both technologies were initially developed with NASA's Innovative Partnerships Programs (IPPs). These components and the results from their flight demonstration support future small spacecraft and satellite development with a goal toward simplifying development and operations infrastructure.

    In summary, the objectives of the TechEdSat investigation include:

      A. Develop ground control and flight systems to be ready for ISS by June 2012. The flight system is designed to support soft stowage in ISS for a long period of time.

      B. Primary technologies demonstration objectives: 1). Demonstrate the rapid, cost-effective development and integration of 1U for space flight. 2). Evaluate the AACs plug-and-play electronics architecture. 3). Send radio packets from at least of two modules. 4) Be able to track the cubesat from launch to re-entry.

      Applications

      Space Applications
      The benefits from the TechEdSat investigation include a demonstration of rapidly reconfigurable Nanosat technologies for the development of future space craft. In addition, such a demonstration may ultimately reduce costs for Nanosatellite bus development, eliminate the need for physical ground station interfaces for Nanosatellites, and prove that the ISS is a reliable platform for CubeSat deployment.

      Earth Applications
      CubeSat technologies provide an array of small satellites that can be efficiently developed and deployed for a variety of research and technological purposes. By demonstrating the TechEdSat technologies with regards to communication and tracking, CubeSat ground communication systems can be designed more efficiently in order to process and transmit satellite data. Also, the TechEdSat should help demonstrate evolving, quick return capabilities for scientific samples and hardware from the ISS.

      Operations

      Operational Requirements
      TechEdSat is deployed from the JEM Small Satellite Orbital Deployer (J-SSOD) attached to the JEM Remote Manipulator System (JEMRMS). The Space Station Remote Manipulator System (SSRMS) is required for viewing support during deployment from the ISS.

      Operational Protocols
      TechEdSat requires ISS Crew to remove the Remove Before Flight (RBF) pin inside the JEM before the J-SSOD is transferred out through the JEM Airlock. The deployment switches then turn on after the satellite is ejected from the J-SSOD in order to prevent inadvertent satellite appendage deployment within the J-SSOD. The JEMRMS is used to retrieve the J-SSOD from the JEM airlock and moves it to the appropriate and safe deployment orientation.
