(Redirected from GLACIER freezer module)

The Minus Eighty-Degree Laboratory Freezer for ISS (MELFI) is a European-built experiment storage freezer for the International Space Station. It comprises four independent dewars which can be set to operate at different temperatures. Currently[when?] temperatures of −80 °C, −26 °C, and +4 °C are used during on-orbit ISS operations. Both reagents and samples will be stored in the freezer. As well as storage the freezer is designed to be used to transport samples to and from the ISS in a temperature controlled environment. The total capacity of the unit is 300 litres.

Minus Eighty-Degree Laboratory Freezer for ISS

History

The first MELFI[clarification needed] unit, FU-1, was flown to the station in 2006 on Space Shuttle mission STS-121, installed in the Destiny Laboratory Module, and commissioned by Thomas Reiter.[1]

The MELFI flight units were originally designed to be flown fully powered in the Multi-Purpose Logistics Module, permitting pre-made experiments to be flown to the station without contaminating or destroying any samples.

The plan[when?] was to cycle the three MELFI units between orbit and Earth.[citation needed]

The final MELFI unit was flown to the ISS on board Space Shuttle Discovery during the STS-131 mission in 2010.

MELFI description

Dewars are cylindrical, 75-liter vacuum-insulated containers that may hold samples of various sizes and forms. A number of extra dewars were also delivered with the unit at first.

MELFI was developed by the European Space Agency. Two units have been supplied to NASA and one to the Japan Aerospace Exploration Agency (JAXA). In addition ground units for training, experiment preparation, and use in control experiments have been built.[2]

  • Weight: 730 kg (1609 pounds)
  • Design lifetime: 10 years.
