The Voyager 1 and Voyager 2 space probes, both launched in 1977, each
had a primary objective to explore Jupiter and Saturn. This goal was
achieved by 1981. Yet Voyager, NASA's longest running mission, has
continued to this day. Both Voyager probes are still operating, and
returning scientific data from outside our solar system.
This talk explores the computing systems of Voyager - the systems which
enable remote control of the spacecraft, and provide for the recording
and return of data to Earth. These systems have proved to be both
adaptable, durable, and resilient in support of a scientific undertaking
now in it's fifth decade.
What can we learn from the engineering of Voyager's computing systems?
Why have they survived for so long in the harsh environment of space?
What is involved in patching a system from a billion miles away? And
what does the future hold?
