The use of nuclear reactors as power plants for electrical rocket engines (RSC Energia concept till 1988) necessitated the development of a high-power Nuclear Power Plant (NPP) based on lithium-niobium technology. ... Based on the experience gained in the experiments, RSC Energia has developed designs for space NPPs and electrical power propulsion units. ...

... Star Atlas . ... stars . ... Nuclear fusion of hydrogen into helium powers stars, but fusion requires a lot of energy. Where does this energy come from? ... You re in good company: This question also stumped the physicists who first tried to understand nuclear fusion in stars. In a star s core, all atomic nuclei have been separated from their electrons, so each hydrogen atom is really just a proton and thus holds a positive charge. ...

... The total mass of the scientific payload is about 2500 kg, of which the unfolding parabolic 10-m radio astronomy antenna's mass is about 1500 kg, and scientific package holding the receivers, power supply, synthesizers, control units, frequency standards and data transmission radio system - near 900 kg. ... The jet system is a hydrazine thrusters system: it will be used during the creation of the base system of spacecraft orientation, for unloading of the powered gyros, and for orbit corrections. ...

XMM-Newton Science Analysis System . ... These subroutines calculate the power (in watts) radiated per unit surface area (m2) per unit solid angle (sr) by a black body at temperature='kelvin'. The power can be calculated either per unit frequency, at a given frequency (both in hertz), or per unit wavelength (in metres) at a given supplied wavelength (in angstroms). ... Per unit frequency . Per unit wavelength . XMM-Newton SOC/SSC -- 2008-07-01 ...
