LEMUR-2-Monson, one of Spire Global's LEMUR-2 constellation satellites — compact 3U CubeSats carrying ADS-B aircraft tracking, monitoring flights even over oceans where ground radar has no reach. Spire's tradition of giving individual satellites human first-and-last names, rather than sequential numbers, makes its constellation of hundreds feel oddly personal for a fleet this size.
