When astronomers make observations in radio, they can increase the resolution by using a technique called very long baseline interferometry. Currently, the longest baselines that are available in this technique are limited to the size of the Earth, but in the future, it may be possible to extend the baseline used in interferometry by incorporating a satellite in space. This article explores this idea of extending very long baseline interferometry to space and offers ways of correcting the observed signal due to motions of the satellite.
