Imaging Planets About Other Stars with UMBRAS II

摘要

Large space-based telescopes have specific design requirements which offer challenges to the instrument designer. The optical design and detector fabrication are frozen years before the launch date. The Umbral Mission Blocking Radiating Astronomical Sources (UMBRAS) space mission design consists of a Solar-Powered Ion-Driven Eclipsing Rover (SPIDER) and possibly one or two metrology platforms. The ultimate goal of UMBRAS is to provide pseudo-coronagraphic capability for direct imaing of extrasolar Jovians and other brighter, distant substellar companions.
