Despite our space program doing some impressive things -- just think of the videos of Saturn's rings taken by the Cassini satellite -- the technology handling space exploration is surprisingly dated.
According to this Silicon.com article, "To this day, Nasa still uses elements of technology that powered the moon landings of the 1960s and 1970s, while the International Space Station (ISS) -- the manned station circling the Earth 250 miles above our heads -- relies on processors dating back more than two decades".
