Hexagon 2

 1972-002A

---

Mission 1202, the second HEXAGON or Big Bird, was launched in Jan 1972 to carry out a survey of Soviet strategic forces. It carried out orbit raising burns every few days until Feb 18, after which it steadily decayed until deorbit on Feb 28. The film broke in one camera during the RV-3 phase so RV-3 and RV-4 returned only monochromatic rather than stereo imaging.
