Narrow Results

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 geodesics in 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 way. We point out, using the Pioneer satellites as an example, that current satellite technology allows for this possibility within time scales less than one human lifetime.
