Throughout the years, microprocessors have played a large role in spacecrafts. space-qualified microprocessors are designed to be exceptionally reliable and highly durable. Due to their unique nature, the same set of chips that have been tested and proven to work are used in many spacecrafts. Below is a list of microprocessors used in spacecraft.
Description: The Mercury spacecraft, NASA's first human spaceflight, had barely enough space for a single occupant. The spacecraft had no independent maneuvering capabilities - relying completely on the Atlas booster rocket. Because of that, it was unnecessary for the spacecraft to have a dedicated on-board computer. Limited functionality was done by various smaller systems.
The Pioneer 10, which was launched on March 3, 1972, became the first spacecraft to achieve escape velocity from the Solar System. The spacecraft's process were made of individual transistor-transistor logic chips. A common myth is that the Intel 4004 powered the Pioneer 10, however, this is incorrect.
The Voyager 1 and its sister craft Voyager 2 were launched on September 5 and August 20 of 1977 and are still operating to date (2014). On August 25, 2012, NASA announced that Voyager 1 entered interstellar space.
