Although space is a vast frontier, there is a relatively high launch and transportation cost per unit mass of payload. This requires maximizing the payload functional performance while also minimizing the required supporting payload power, mass and volume. The high access cost to space has spurred the development of lower‐cost nanosat and microsat orbital platforms for Earth Observation and microRovers for landed planetary exploration. However, these require suitable miniaturized payloads with sufficient performance to provide meaningful measurements and new science capabilities. In this respect, optical spectroscopy has been widely used for space systems to provide valuable information on the molecular composition and bonding in gases, solids and liquids for atmospheric studies, landcover mapping, planetary mineralogy and astrobiology. This chapter provides an overview of three technologies for miniaturized optical spectrometers to enhance the capabilities of low‐cost microsat and microRover platforms; high‐performance integrated guided‐wave spectrometers, monolithic Fabry‐Perot imaging spectrometers, and Dyson hyperspectral imagers.
