The ITU Radiocommunication Assembly considering a)that a large number of atomic and molecular spectral lines are observed at frequencies above 70 GHz, and that many of these lines are of great importance to astronomy but only few fall within bands allocated to radio astronomy; b) that these spectral lines along with continuum observations provide unique information about star formation, including the formation of planets in other solar systems, the existence of pre-biological molecules and extra-terrestrial life, the physics and chemistry of the interstellar medium, the history of the universe, and about other astrophysical processes of great interest.
