An advanced cryogenic ratchet wheel drive has been developed based on experience from the GIRL project. Power dissipation, microphony, lifetime and positioning accuracy have been significantly improved. Three of these wheels equipped with filters, apertures and mirrors compose the core of the photom

β¦ Synopsis
Subsystems for a proof of concept'' cryogenic payload have been developed to demonstrate the ability to accommodate low temperature science investigations within the constraints of the Hitchhiker siderail (HH-S) carrier on the Space Shuttle. These subsystems include: a hybrid solid neon Β± superΒ―uid helium cryostat, a multi-channel Versa Modular European (VME) architecture Germanium Resistance Thermometer (GRT) readout and heater control servo system, and a multiple thermal isolation stage probe'' for thermal control of helium samples. The analysis and tests of these subsystems have proven the feasibility of a cryogenic HH-S carrier payload.
