Previous investigations have reported that bacterial growth increases in space flight; however, the underlying physical mechanisms responsible for these changes have not been fully determined. As bacteria consume nutrients, they excrete by-products whose presence can influence the onset of exponential growth and affect final cell population density. It is assumed that these metabolic processes create a reduced-density fluid zone and/or a solute gradient around each cell. On Earth, this density ...
Performance tests were conducted by the National Aviation Facilities Experimental Center (NAFEC) on the air traffic control radar beacon system (ATCRBS) type I flight inspection monitor (FIM-I). The FIM-I equipment was then installed on a NAFEC test aircraft for limited flight testing in the mid-Atlantic states. Software was developed for data reduction and postflight analysis to evaluate the performance of the FIM-I equipment. Laboratory performance tests showed that the equipment ...
