Nomenclature AU Astronomical Unit equaling 149,597,870.691 km;the average distance from the Earth to the Sun Delta V(AV)Change in velocity,or delta-V,in m/sec is a measure of energy required to change position in space. Isp Specific impulse in seconds Z value Figure of merit for thermoelectric devices expressed in a ratio per degree Kelvin Definitions Architecture is the selection and arrangement of the concept elements that address the goals,technical requirements,economic and policy influences and ultimately the needs of the customers and stakeholders. Dynamic Mission Planning can be defined as the ability to change target science destinations throughout the mission execution phase as the result of new information or opportunities not previously accounted for during initial mission planning Planetary Mission Class is defined as a set of robotic exploration missions within the solar system that range from near solar to Kuiper Belt object observation. The Kuiper Belt is a disk-shaped region past the orbit of Neptune approximately 30 to 100 AU from the Sun containing many small icy bodies.It is now considered to be the source of the short-period comets. Specific Mass is the ratio of power system mass to power produced measured in kg/kW. bNomenclature AU Astronomical Unit equaling 149,597,870.691 km; the average distance from the Earth to the Sun Delta V (∆V) Change in velocity, or delta-V, in m/sec is a measure of energy required to change position in space.
