The National Academies’ 2020 Decadal Survey on Astronomy and Astrophysics resoundingly endorsed Cosmic Explorer, stating that a next-generation gravitational-wave observatory in the United States is “central to achieving the science vision laid out in the survey’s roadmap.” The Cosmic Explorer Consortium appreciates the support we have received from the Astro 2020 survey, which states that:
“Gravitational wave astrophysics is one of the most exciting frontiers in science. One of the survey’s key priorities is the opening of new windows on the dynamic universe, with gravitational wave detection at the forefront. The continued growth in sensitivity of current-generation facilities, such as LIGO, through phased upgrades and planning the next-generation observatory, such as Cosmic Explorer, is essential. This will require investment in technology development now. The survey committee strongly endorses gravitational wave observations as central to many crucial science objectives.”
