The latest decadal survey, which charts the course for U.S. astronomy and astrophysics from 2022 to 2032, recommends that NASA create a new program to develop several major space telescopes at a time. Five years after starting work on that first flagship mission, NASA should begin developing both a far-infrared mission and an X-ray mission, each costing an estimated $3 billion to $5 billion, the survey recommends. On the ground, astronomers’ highest priorities, according to the decadal survey, are continuing to build two major optical observatories, the Giant Magellan Telescope in Chile and the Thirty Meter Telescope in Hawaii — though the latter project has faced controversy (SN: 8/5/20).
