Editing microprocessors used in spacecrafts

Throughout the years, [[microprocessor]]s have played a large role in spacecrafts. [[space-qualified microprocessor]]s are designed to be exceptionally reliable and [[radiation hardening|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 [[Wikipedia:Mercury spacecraft|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 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.

Just like it's twin probe, the Pioneer 10, its CPU was also a custom-designed [[transistor-transistor logic|TTL]] CPU.

The [[Wikipedia:Viking 2|Viking 2]], was launched a year later on September 9, 1975 The computer on-board the Viking Orbiter was the [[Viking Orbiter CCS]], a custom 18-bit TTL computer designed by General Electric. The lander computers, the [[Guidance, Control and Sequencing Computer]], used two [[Honeywell HDC 402]] microprocessors. (A common myth is that the Viking used an [[RCA 1802]], this is incorrect).

On August 25, 2012, NASA announced that Voyager 1 entered interstellar space.

Each craft carries three dual-redundant computer systems. The first one, the [[Voyager Command and Control Subsystem]] (CCS), was in charge of general spacecraft sequencing and general health functionality. The second one, the [[Voyager Attitude and Articulation Control Subsystems]] (AACS) used a slight variation of the CCS. The third computer was the [[Voyager Flight Data System|Voyager's data computer]], which was a custom 4-bit CMOS microprocessor.
