1967-068A
Surveyor 4 was launched at 1153 on 1967 Jul 14 on a single burn direct ascent trajectory using the LV-3 Atlas. The main engine cutoff was at 1205. The Centaur made test evasive maneuvers at 1206 and 1214. Surveyor IV made a course correction on Jul 16. Contact was lost 41.1s into the 42.5s retroburn, 0203 on 1967 Jul 17. Lunar impact occurred at 0.47N 1.44W; it is assumed the Star 37 exploded.
