EVA 17A

iss014e14541 (2/22/2007) --- A view of the BTN-ME experiment, also called BTN-Neutron experiment, attached to the Zvezda Service module as seen by the Expedition 14 crew during Russian EVA 17A. The BTN-ME experiment builds a physical model for generation of charged and neutral particles during solar flares. It also develops a physical model of neutron albedo of the earth atmosphere with regard to helio- and geophysical environment, measurement point longitude and altitude effects, time of the day and lighting conditions, atmosphere conditions. Also it develops a physical model of neutron background in the vicinity of the ISS in different flight conditions, as well as recording space gamma bursts.
