Crystal 6

 1984-122A


CRYSTAL 6 was launched into a late afternoon 0941 LTDN west-plane sun-synchronous orbit. The higher apogee of this mission reflected the KENNEN system's takeover of the HEXAGON's wide area search mission in addition to the core KH-11 close-look capability. D. Day notes that the search mission is performed at apogee and in a sun-synchronous orbit the orbital plane would be 180 degrees from a high resolution mission looking at the same target at perigee.
