MERLIN (Microgravity Experiment Research Locker Incubator) is a thermal carrier that has been approved for flight in Middeck and EXPRESS Rack accomodations. MERLIN is a rear-breathing Middeck Locker (MDL) replacement incubator that provides a thermally controlled environment for scientific experiments in the International Space Station (ISS) EXPRESS Rack, or the now retired Space Shuttle. Also used to support Crew Galley Operations.

  • Advanced Single Middeck Locker Incubator / Freezer (Heat exchanger designed for both rear-air or water loop heat rejection)
  • Previous interfaces include Shuttle Middeck and SPACEHAB
  • Capable with interfacing with Commercial Orbital Transportation System (COTS) vehicles
  • 30+ pound payload with 16.5" (X) by 10.188" (Y) by 6.69" (Z) experiment volume (CG at the center of the experiment volume)
  • Payload volume for both conduction or convection cooling modes
  • Provides thermal control from -20oC to 48.5oCMERLIN_png_patch
  • Fully programmable temperature control including ramps and recovery modes can be configured / executed via the display, EXPRESS RIC, and remotely from the ground (both commanding and file uplink)
  • System temperature sensor readings (8)
  • Experiment temp. sensor readings (up to 12)
  • PID control temperature (derived)
  • A/D sensor readings (up to 10)
  • Digital I/O readings (8)
  • Last command status information
  • Error reporting/acknowledgement information
  • Data storage utilization status
  • Thermal control data
