Explorer 6

Explorer 6NASA launches the Earth-orbiting satellite Explorer 6 atop a Thor-Able rocket, intended to study various space and upper atmospheric phenomena, as well as to take photos of Earth with an experimental camera system designed to refine engineering concepts for monitoring weather from orbit. Explorer 6 does indeed capture the first (admittedly less than ideal) photo of Earth taken from orbit, from a vantage point of 17,000 miles above Mexico in its elliptical orbit. Explorer 6 will remain in orbit for just under two years.
