The first spacecraft to approach the planet Saturn was launched 50 years ago on a 1.5 billion mile trip to Earth’s distant neighbor. During its 22-year mission, Pioneer 11 studied the asteroid belt, the solar wind, cosmic rays and the environment around the planets Jupiter and Saturn. The probe was part of the United States’ efforts leading the reconnaissance of each planet in the solar system.
Marianna Triplett was working at the Pentagon, continuing the effort to transfer millions of men and women back to civilian life after they served in the military during World War II. One day during 1948, a U.S. Army general called her into his office and said he wanted to transfer her to Florida to assist with a “hush-hush secret program.” The new effort building Cape Canaveral Space Force Station would lead to some of the most historic achievements of the decades to come.
NASA’s Gemini IX mission was another step in developing technology for future spaceflights from Apollo to the agency’s upcoming Artemis Program designed to return astronauts to the Moon followed by exploration of Mars. But, this 1966 mission included developing alternate plans when faced with the unexpected.
In early 1966, Gemini VIII chalked up another crucial spaceflight technology milestone for the United States. But the triumph quickly became an in-flight emergency, testing NASA’s quick-thinking skills to bring the astronauts safely home — 55 years ago this month.
