Claim:
1. A testbed for conducting an experiment in a microgravity environment on a substance in a cryogenic liquid state, the testbed comprising: a source section comprising a storage tank that stores a compressed gas comprising the substance to be evaluated in the cryogenic liquid form; an experiment section comprising an experiment vessel in fluid communication with the storage tank to receive the compressed gas from the storage tank and condense the compressed gas into the cryogenic liquid state; a sensor adapted to sense a property of the cryogenic liquid in the experiment vessel as part of the experiment in the microgravity environment; and a bus section comprising a controller configured to control delivery of the compressed gas from the storage tank to the experiment vessel, and to receive property data indicative of the property sensed by the sensor for subsequent evaluation on Earth, all of said source section, said experimental section and said bus section being disposed in a frame having rectangular nominal dimensions.
