First Man into Space (working title: Satellite of Blood) is a 1959 independently made British-American black-and-white science fiction-horror film. It was produced by John Croydon, Charles F. Vetter, and Richard Gordon for Amalgamated Films and was distributed by Metro-Goldwyn-Mayer. Directed by Robert Day, it stars Marshall Thompson, Marla Landi, Bill Edwards, and Robert Ayres. The film is based on a story by Wyott Ordung, while the plot was developed from a script that had been pitched to and rejected by AIP.

Plot

U. S. Navy Commander Charles "Chuck" Prescott (Marshall Thompson) is unsure if his brother, Lt. Dan Prescott (Edwards), is the right choice for piloting the high altitude, rocket-powered Y-13. Air Force Space Command's Captain Ben Richards (Robert Ayres) insists that Dan is their best pilot, even though when piloting the Y-12 in the ionosphere, he began experiencing difficulties. Dan ignored flight regulations upon landing by seeing his girlfriend (Marla Landi) rather than filing his flight report. Captain Richards, however, insists that Dan pilot the Y-13 after being checked out and briefed by Dr. Paul von Essen (Carl Jaffe).
