1967-070A
The second AIMP, AIMP-E (Anchored Interplanetary Monitoring Platform E or Explorer XXXV) was launched at 1419:02 on 1967 Jul 19 by Delta E1 from Cape Kennedy. It featured an improved attitude control system which could have overcome AIMP-D's problems. AIMP-E successfully reached lunar orbit, with an insertion burn at 0919:25 on Jul 22 into a 691.8 min, 2538 x 9429 km x 169 deg orbit (inclination relative to ecliptic plane). The angle between apoapsis, Moon and Sun was initially 304 deg in selenocentric solar ecliptic coords. The Star 13 motor separated by around 1130. The orbit had changed to 712.0 min, 715 x 7760 km x 171.0 deg by 1972. The probe carried on transmitting until 1973 Jun 24.
