A rotating spacecraft which encloses an atmospheric pressure vessel poses unique challenges for thermal control. In any given location, the artificial gravity vector is directed from the center to the periphery of the vehicle. Its local magnitude is determined by the mathematics of centripetal acceleration and is directly proportional to the radius...

The MIT-based Mars Gravity Biosatellite payload engineering team has been engaged in designing and prototyping sensor and control systems for deployment within the rodent housing zone of the satellite, including novel video processing and atmospheric management tools. The video module will be a fully autonomous real-time analysis system that takes...

... One of the main challenges in the design of capsules or habitats is ammonia as a final product of chemical degradation of chemical waste such as urine [42]. According to international guidelines on the care and welfare of laboratory animals, elevated levels can cause alterations in biological responses [43]. ...
... Fan location has been optimized, subject to both constraints in thermal flow as well as the data from the mockup experiments [5]. A more detailed discussion of the thermal control system can be found in References [5] and [8]. ...
