In Development

  • LEONIDAS, Low Earth Orbiting Nanosatellite Integrated Defense Autonomous System.
  • Objective: Increase access to space for DoD, NASA, and University payloads--such as short-duration technology demonstration missions. As the prime contractor, HSFL will conduct two demonstration space launches from the Navy's Pacific Missile Range Facility in Hawaii using a low-cost launch system based on an upgraded, three-stage solid propellant, Sandia National Lab Strypi ballistic rocket. (Note: STU is a mission designation that stands for Science And Technology for the University.)
    • STU-1: First LEONIDAS Mission
    •     » Objectives : Deployment of rideshare satellites in low-Earth orbit, flight test of SPARK launch vehicle and insertion accuracy, dynamic test of launch rail.
          » Orbit : 400 km Sun-synchronous orbit
          » Payload Mass : 50-60% mass capacity (~165 kg)
          » Potential Payloads : CubeSat Payload Adapter and Small Satellite
    • STU-2: Second LEONIDAS Mission
    •     Objectives : Full payload deployment test, deployment of HawaiiSat-1 and rideshare satellites in low-Earth orbit.
          » Orbit : 550 km Sun-synchronous orbit
          » Payload Mass : Full capacity
          » Potential Payloads : CubeSat Payload Adapter, HawaiiSat-1, Small Satellite
  • HawaiiSat-1, Remote Sensing Mission for Radar Calibration and Thermal Hyperspectral Imaging.
  • Goal : Build a remote sensing capability in low-Earth orbit for advanced technology and science instrumentation. HSFL has parallel development efforts on the spacecraft and instruments.
    Objectives :
        » Self-sustaining orbital satellite fabrication and launch activity leveraging existing State assets.
        » Job training for hi-tech launch-centered workforce.
        » Low-cost path for space hardware validation.
        » Increased capabilities in research and development for the Pacific Missile Range Facility, the University of Hawaii, and Hawaii hi-tech businesses.

  • Partner with HSFL to advance small spacecraft design.
  • Join HSFL on technology validation missions.
  • With HSFL, call on a diverse group of instrument-developing faculty from the U. H. Hawaii Institute of Geophysics and Planetology and the School of Ocean and Earth Science and Technology.
  • Use the HSFL clean rooms for systems integration, thermo-vac testing, vibration /shock testing, and payload spin balancing.
  • Participate with HSFL on the design of software and hardware tools to support spacecraft mission operations.
        +  Contact HSFL to discuss all options.

Launch Support

The Pacific Missile Range Facility (PMRF), Kauai, is the world's largest instrumented multi-environment range capable of supporting surface, subsurface, air, and space operations simultaneously. PMRF offers polar and Sun-synchronous launch options. HSFL will utilize a newly designed launcher.
