Also known as 1962 Tau Beta (among other names), the Poppy spacecraft were a follow-on to the Galactic Radiation and Background (GRAB) series of ELINT satellites, pictured in this previous blog entry. Several Poppy spacecraft were launched together, in tandem with the Injun 3 instrumentation satellite.by
