User:PhotographyEdits/Computer systems in space
Embedded computer systems deployed to outer space have various constraints, such as data links to earth that are low bandwidth and high latency. Additional constraints require radiation hardening and supporting a large operating temperature range, which limit the processing power. Some systems have been returned to earth in working state, like the Apollo Guidance Computer, others are still functioning like the board computer of the Perseverance Mars rover. Some systems still exist but are no longer reachable, have burned down in the earth atmosphere, or crashed into other celestial bodies.
