ISS Science for Everyone

Science Objectives for Everyone
The JEM Small Satellite Orbital Deployer (J-SSOD) provides a novel, safe, small satellite launching capability to the International Space Station (ISS). The J-SSOD is a unique satellite launcher, handled by the Japanese Experiment Module Remote Manipulator System (JEMRMS), which provides containment and deployment mechanisms for several individual small satellites. Once the J-SSOD including satellite install cases with small satellites are installed on the Multi-Purpose Experiment Platform (MPEP) by crewmembers, it is passed through the JEM airlock for retrieval, positioning and deployment by the JEMRMS.

Facility Description

Facility Overview

The J-SSOD facility is the first of its kind to deploy small satellites from an orbiting space station, the ISS. J-SSOD provides a reliable, safe and economically viable means of deploying small research satellites into Earth’s atmosphere or return small objects and samples to the ground for testing and analysis. This facility supports research from multiple users and future CubeSat investigators

The Multi-Purpose Experiment Platform (MPEP) is a platform that acts as an interface between operations inside and outside the ISS, and the J-SSOD mechanism is installed on this platform. Two rectangular, spring loaded satellite cases accommodate up to 3 small 1U (10 cubic cm) cube satellites each. Brackets on the satellite install case base provide attachment points for the MPEP which attaches to the JEM Slide Table for passage through the JEM airlock. Individually launched, pre-packed satellite install cases are installed in J-SSOD by crewmembers, attached to the Multi-Purpose Experiment Platform (MPEP) and passed through the JEM airlock for retrieval by the JEMRS. A JEMRMS grapple fixture supports capture, orientation and deployment operations, including communications and power interfaces.

The Space Station Remote Manipulator System (SSRMS) and other ISS cameras may be used to support video monitoring of satellite deployment as necessary. Deployment of small satellites requires a specific JEMRMS orientation (i.e., safe deployment cone) in order to avoid ISS contact.

Expedition 33 saw the first use of the JSSOD facility with the successful deployment of 5 small CubeSat investigations: RAIKO, FITSAT-1, WE WISH, NanoRacks CubeSat-1/F-1 and TechEdSat.
  • Satellite name: RAIKO
    Size: 2U
    Objectives:

    • - Image the Earth using a fish-eye lens camera
      - Photographically measure satellite movement relative to JEM using a Panoramic Color Camera (PCC)
      - Star sensor testing
      - A de-orbit experiment testing a deployable membrane mechanism
      - Testing a small mobile ground station for receiving signals via international cooperation
      - An orbit determination experiment using Ku-band radio frequency Doppler measurements
      - A high-speed Ku-band data communication experiment.

    Satellite name: FITSAT-1
    Size: 1U
    Objectives:

    • - Technical demonstration of a high-speed small satellite transmitter module to send VGA resolution JPEG images in 5-6 seconds
      - Conducting an "artificial star" optical communications test utilizing high output visible light LEDs
      - FITSAT-1 (NIWAKA).

    Satellite name: WE WISH
    Size: 1U
    Objectives:

    • - To promote technology education and the utilization of small satellite data
      - To test an ultra-small thermal infrared camera for ground temperature observations.

    Satellite name: TechEdSat
    Size: 1U
    Objectives:

    • - Demonstrate Swedish designed Space Plug-and-Play Avionics (SPA) hardware and software.

    Satellite name: NanoRacks CubeSat-1/F-1
    Size: 1U

Operations

Facility Operations

  • Once the satellite install cases with pre-packed small satellites, CubeSats, have been received onboard, crewmembers unpack and install them onto Multi-Purpose Experiment Platform (MPEP), which is already installed onto JEM AL Slide Table, along with other equipment related to the J-SSOD mechanism.


  • After J-SSOD installation is complete, the crew commands the JEM AL to extend J-SSOD outside for retrieval.


  • Then, ground operators, controlling the JEMRMS, retrieve the J-SSOD from the JEM Slide Table, and maneuver the JEMRMS to the appropriate deployment orientation.


  • Small satellites are commanded to deploy and subsequently monitored by their respective investigation teams.


  • J-SSOD is returned to the airlock and stowed inside the ISS JEM module.
