SCORE

  1958-006


The first space communications experiment was SCORE, a small package developed by the US Army Signal Corps under the sponsorship of ARPA. SCORE was an acronym for Signal Communications by Orbital Relay Experiment. The package containing two transmitters for handling voice and teletype messages remained attached to the Atlas 10B rocket, which was also the first Atlas stage to enter orbit. The mass in orbit was 3900 kg, of which 68 kg was the payload, the first built by RCA/East Windsor. A special low drag nose cone and adapter were added.

Saturn SA-2

  1962-S108


The second Saturn I launch was SA-2, which was launched at 1400 on 1962 Apr 25. The dummy Saturn S-4-2 and S-V-2 carried 86000 kg of water. At an altitude of 105 km at T+162s the rocket was destroyed on command, allowing atmospheric scientists to study the effects of a large disturbance in the atmosphere. The huge cloud of ice crystals rose to an apogee of 161 km. The experiment was called Project High Water.

DFH-12

 1982-090A


FSW No. 5 (PRC 10) was launched in Sep 1982 on a 5 day mission. The new spacecraft had a CCD camera as well as the standard film camera. The apogee was reduced by 80 km relative to earlier flights.

A debris object was cataloged as decaying on Sep 11, 2 days after launch, from an 860 km apogee orbit. It may have been a separation motor cover.

Explorer 35

  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.
