The Galileo Near Infrared Mapping Spectrometer (NIMS) observed asteroid 243 Ida during a close encounter on August 28, 1993, at a heliocentric distance of 2.95 AU.
We have constructed a computer model to simulate synchrotron emission from relativistic electrons trapped in Jupiter's magnetic field.
Selective surfaces have wavelength dependent emissivitya bsorption. These surfaces can be designed to reflect solar radiation, while maximizing infrared emittance, yielding a cooling effect even in sunlight. On earth cooling to -50 C below ambient has been achieved, but in space, outside of the atmosphere, theory using ideal materials has predicted a maximum cooling to 40 K! If this result holds up for real world materials and conditions, then superconducting systems and cryogenic storage can be achieved in space without active cooling. Such a result would enable long term cryogenic storage in deep space and the use of large scale superconducting systems for such applications as galactic cosmic radiation (GCR) shielding and large scale energy storage.
