In late 1957, teams at JPL worked on the complex pieces required to build the Explorer 1 satellite. Here, Explorer 1 is test-mated before launch by engineers (from left) John Small, Gene Hendricks and Dee Trimble. Explorer 1 was launched successfully on Jan. 31, 1958, and became the first satellite to carry science instruments.
