This sketch by rocket engineer Wernher von Braun informed Fred Freeman’s illustrations for the 27 June 1953 issue of Collier’s, part of a series entitled “Man Will Conquer Space Soon.” The series detailed von Braun’s plans for human spaceflight; he imagined the “baby satellite” staying in orbit for 60 days and carrying monkeys, TV cameras, antennas, solar mirrors, and Geiger counters. The sketch sold for $12 200.
