LEMUR-2-Bass, one of Spire Global's hundreds of nearly identical CubeSats, each given a genuine human name rather than a serial number — a deliberate quirk that makes a fleet this size feel oddly personal. This one carries an AIS receiver tracking ship transponder signals across open water, part of a maritime surveillance network dense enough to spot a vessel that thinks it's alone.
