This year, as NASA celebrates its 50th anniversary, we’ll be highlighting technology innovations and important moments in NASA history, leading to our special 50th Anniversary Issue in October.

This Month in NASA History: On July 29, 1958, President Dwight D. Eisenhower signed the National Aeronautics and Space Act, which created a space agency to achieve the goal of a manned spaceflight program. On July 8, 2003, the Mars Explorer Rover-B, also known as Opportunity, launched from Cape Canaveral. It was an exact copy of its “sister,” MERA, also known as Spirit, which had launched a month earlier. The two rovers are still acquiring data on the Martian surface.
