After Magellan 30 years ago, US Venus exploration has relied on archived data, Earth-based and flyby observations of missions bound elsewhere, and international efforts such as Venus Express (ESA) and Akatsuki (JAXA) until the selection of NASA Discovery missions VERITAS and DAVINCI and participation in ESA's EnVision. These missions will address a significant number of major science questions abo...Show More
NASA Jet Propulsion Laboratory's (JPL's) Architecture Team (A-Team) has nearly a decade of experience in maturing early formulation mission and technology concepts by combining innovative collaborative engineering methods with cutting-edge subject matter expertise and advanced analysis tools in an in-person environment. When COVID-19 forced JPL's workforce to work remotely in March 2020, A-Team ha...Show More
Diffraction gratings are commonly used in optical instruments such as in spectrometers, monochromators, and wavelength division multiplexing devices. The diffraction efficiency is directly related to the ratio of the grating spacing or pitch to the wavelength of the light. In a sinusoidal grating (or holographic grating) the efficiency is generally lower than a blazed grating with a saw tooth prof...Show More
