  Cosmological expansion on a local scale is usually neglected in part due to
its smallness, and in part due to components of bound systems (especially those
bound by non-gravitational forces such as atoms and nuclei) not following the
geodesics of the cosmological metric. However, it is interesting to ask whether
or not experimental tests of cosmological expansion on a local scale (well
within our own galaxy) might be experimentally accessible in some manner. We
point out, using the Pioneer satellites as an example, that current satellite
technology allows for this possibility within time scales of less than one
human lifetime.
