Luna 11

  1966-078A


Luna-11 was a modified lunar satellite, designated E-6LF No. 101. The E-6LF probes were larger than Luna-10 and the instrument section did not separate from the DU. It was intended for lunar photography, but the attitude control failed after orbit insertion and the images were of deep space instead of the Moon.

Explorer 18

 1963-046A


IMP A (Interplanetary Monitoring Platform A, or Interplanetary Monitoring Platform 1 after launch) was the first in the series. The old NASA designation was S-74; the flight spacecraft was S/N 02.

Launch was 1963 Nov 27, 0230:01 by Delta C from Canaveral LC17B. Orbit insertion was at 0236:07 into a 192 x 197616 km x 33.3 deg orbit; the planned apogee was 277000 km but the Altair stage underburned. IMP I operated until 1965 Mar 25. The satellite was also called Explorer 18.
