A year in orbit: ISS deployment tests radiation detectors for future space missions
The predawn darkness on a cool Florida night was shattered by the ignition of nine Merlin engines on a SpaceX Falcon 9 rocket. The thrust of the engines shook the ground miles away. From a distance, the rocket appeared to slowly rise above the horizon. For the cargo onboard, the launch was anything but gentle, as the ignition of liquid oxygen generated more than 1.5 million pounds of force. After the rocket had been out of sight for several minutes, the booster dramatically returned to Earth with several sonic booms in a captivating show of engineering designed to make space travel less expensive and more sustainable.

The prompt fission neutron energy spectrum of 235 U was measured at an incident neutron energy of 0.40 MeV with two samples of different thickness. The data were corrected for flux attenuation in the sample material and for effects due to the energy change of the out-going fission neutrons by inelastic scattering and secondary fission processes. After applying these shape corrections, an average fission neutron energy of 2.06 ± 0.05 MeV was obtained using the Watt and the Maxwellian functions for the energy distribution of the fission neutrons. This result has been compared with the presently available results of other works.
