## Editorial
MX (Cartosat-3) is the four-band multispectral VNIR camera on Cartosat-3, separate from the mission's panchromatic PAN camera.[^nrsc-cartosat3-brochure][^ceos-mx-cartosat3] It is a passive optical multispectral imager with blue, green, red and near-infrared bands: 450-520 nm, 520-590 nm, 620-680 nm and 770-860 nm.[^nrsc-cartosat3-brochure] The payload uses 11-bit quantisation.[^nrsc-cartosat3-brochure] Ground sampling is 1.12 m [^nrsc-cartosat3-brochure] or 1 m [^ceos-mx-cartosat3]; swath is about 17 km [^nrsc-cartosat3-brochure] or 16 km.[^ceos-mx-cartosat3] Cartosat-3 and its MX instrument are operational/nominal in the mid-2020s.[^wmo-cartosat3-satellite][^ceos-mx-cartosat3] The camera is built for high-resolution land observation and cartography, with capability for vegetation-index workflows, optical time-series change detection and supervised classification from VNIR imagery.[^nrsc-cartosat3-brochure][^ceos-mx-cartosat3]
