Corona 74

 1963-048A


Mission 9061 (CORONA 74) was the second to last MURAL flight and the last CORONA mission to use the standard (no strapons) Thor Agena D launch vehicle. It was also the first CORONA launched from Point Arguello, as Operation DRY DUNE (Ops 2260). Mass was 1375 kg. Agena burn was 7 sec long to make up for low thrust.

After 5 days, on rev 83, SRV separation was commanded, but did not occur. The USGS Web page reports that the SRV separated from the satellite but remained in orbit; the CORONA program summary says the SRV `did not eject properly'. This curious phrasing suggested that it did eject, but possibly in the wrong direction: however, no separate object was tracked in the NORAD satellite catalog.
