terra-aster

14-band multispectral + thermal imager on Terra. The six 30m SWIR bands are the only global SWIR record of the 2000s at that resolution — irreplaceable for mineral alteration mapping. The five 90m TIR bands are similarly unique (nothing civilian matched them until ECOSTRESS). SWIR detector failed April 2008; VNIR and TIR still acquire.
