The problem of active cooling for photo detectors in CubeSats becomes more important because 52% of space missions in 2015-2016 target Earth observation, and passive cooling does not provide the required temperatures of 180-200K to achieve the desired SNR levels. Reciprocating compressors used in cryocoolers cause vibrations. VERT Rotors has built an ultralow-vibration rotary compressor with 40mm-long screws, and our prototype delivered 1:12 compression ratio. This “nano” compressor is a non-conventional conical type consisting of an Inner conical screw rotor revolving inside an Outer screw rotor. The company is working on producing a CubeSat cooling kit based on this compressor.
