Television Observations from Surveyor III

Surveyor III landed on the lunar surface at 00:04 GMT, on Day 110, 1967, approximately 23 hr after local sunrise on the Moon. The first pictures were taken by the television camera at 01:02 GMT. The camera was operated extensively for the first period of lunar visibility from the Goldstone Tracking Station of the Deep Space Network and, except on Day 115, on each successive Goldstone pass of the Moon until the Sun set over the Surveyor III landing site on Day 123. During this period, the Sun rose from an elevation angle of 11° in the east to within 3° of the zenith and then sank almost due west of the spacecraft. Many pictures were obtained of the illuminated eastern horizon in the period immediately preceding sunset. In addition to those received at the Goldstone Station, some were obtained at the Canberra, Australia, station of the Deep Space Network. There were 6315 television pictures taken during the first lunar day of the Surveyor III mission.
