DSP 8
1975-118A
The Flight 5 satellite was actually spacecraft 8 (or possibly 7), the first of the heavier Block II satellites with a mass of 1040 kg. The last Block 1 satellites, spacecrafts 5 and 6, were kept in storage and later upgraded. The enlarged IR arrays had 6000 pixels. Shortly after orbit insertion, a fuel line ruptured (detected by the impact warning sensor) and attitude control was lost but later recovered. The spacecraft remained in a drift orbit in which it saw some operational use.
