Abstract
NASA’s Mars Atmosphere and Volatile EvolutioN (MAVEN) mission advances the understanding of planetary habitability and climate change by investigating how Mars lost its early atmosphere and abundant liquid water. We will present here the UV ruled master diffraction grating design, development and performances provided for the MAVEN mission. We will firstly focus introduce HORIBA Scientific capabilities and heritage for low groove density ruled blazed grating development. Then, we will introduce the grating design with the blazed profile and efficiency optimization and finally the performances characterization we obtained on the flight model gratings.
