Excerpt: Explorational X-ray astronomy is deep space X-ray astronomy performed by an astronomer/explorer or probe that has an X-ray telescope or X-ray detector aboard and leaves Earth orbit. Normally, observational astronomy is performed on Earth's surface, beneath it in neutrino astronomy, or in orbit. An observer becomes a deep space explorer upon escaping Earth's orbit. Exceptions include the Explorer 1 and Explorer 3 and the earlier satellites in the series. The Deep Space Network, or DSN, is an international network of large antennas and communication facilities that supports interplanetary spacecraft missions, and radio and radar astronomy observations for the exploration of the solar system and the universe. The network also supports selected Earth-orbiting missions. DSN is part of the NASA Jet Propulsion Laboratory (JPL). Artist's rendering of MESSENGER orbiting MercuryThe...
