The other priorities established by the panel are the ground-based 30-metre Giant Segmented Mirror Telescope, the space-based Constellation-X Observatory, expansion of the Very Large Array radio telescope in New Mexico, a ground-based 6.5 metre survey telescope, and the Terrestrial Planet Finder. The panel describe this last mission as "the most ambitious space mission ever attempted by NASA."

Other priorities include completion of existing telescopes and missions, a large telescope to detect gamma-rays, an instrument to measure gravitational waves, and a powerful telescope to study the Sun. Among the smaller projects given priority is a "virtual observatory" that would make large sets of astronomical data available to scientists and the public over the Internet.
