• ULA launched a Delta 4 Heavy from Vandenberg on Jan 19, 2019 putting the National Reconnaissance Office′s USA 290 satellite in low polar orbit.
• The satellite is believed to be the first of a new series of imaging spy satellites, probably derived from the Improved CRYSTAL design that in turn descended from the 1970s KENNEN spacecraft which carried the KH-11 camera system. According to a posting on the SeeSat-L observers′ list, its orbit is suspected to be 395 x 420 km x 73.6 deg.
