[Handling and maintenance of gerbils during the spacecraft Foton-M3 mission].
Pressurized low-sized module Kontur with an independent life support system (LSS) was developed by the Institute of Biomedical Problems cooperatively with the Special Design Bureau of Experimental Equipment to house gerbils (Meriones unguiculatus) aboard robotic technology-purpose spacecraft. Design of the module precludes pollution of the environment The fully equipped module weighs 69 kg; average daily power consumption is 62 watts. The environmental parameters for 12 animals flown on Foton-M3 in the period of September 14-26, 2007 were controlled within the following ranges: pO2 - 143-156 mm Hg, (mean 150 mm Hg), pCO2 - 0.76 mm Hg maximum (mean 0.64 mm Hg), temperature - 23-28 degrees C (mean 26.7 degrees C), relative humidity - 29% and 57% at the beginning and end of the flight, respectively (mean 39%). The animals consumed the palletized food prepared of natural products with a moisture content of approx. 20%. The day-night periods were 12 hrs. long. The daytime video recording of the animals went on continuously in the throughout the flight. The experiment showed that the module meets the requirements of experiments with mammals aboard returnable robotic spacecraft and piloted space stations. At the moment, the model is being redesigned for a 30-day BION-M1 mission.
