Here’s a TV Guide Close-Up from May 1965 promoting coverage of the Gemini 4 (or Gemini IV) space flight on all three networks:
The networks started their coverage of the Gemini 4 space flight two days before launch. Or at least NBC did, airing an hour-long preview on Tuesday, June 1st. All three networks aired previews the following day. Coverage of the launch began at 7AM on Thursday, June 3rd and continued the following day.
Gemini 4 was the Gemini program’s second manned mission. James A. McDivitt and Edward H. White II circled the Earth more than 60 times over the course of four days. White also carried out the first American space walk.
