The U.S. government has withdrawn support for the CMB-S4 project, which aimed to study the cosmic microwave background to uncover insights about the universe's origins. The project, which had been underway since 2013 with a $900 million budget split between the Department of Energy and NSF, was designated a top priority by the scientific community. However, on July 10, federal agencies announced they could no longer support CMB-S4. This decision stems from concerns over federal budget uncertainties and declining scientific infrastructure, marking a significant setback for scientific advancement.
The U.S. government has withdrawn support for the CMB-S4 project, a major initiative to study the universe's earliest moments through advanced radio telescopes in Antarctica and Chile.
Initially conceived in 2013, CMB-S4 had been prioritized by astronomers and physicists, with an estimated cost of $900 million split between the Department of Energy and NSF.
A statement on July 10 from federal agencies indicated they could no longer support the project, leading Carlstrom to state that without federal backing, CMB-S4 is effectively canceled.
The cancellation of CMB-S4 reflects broader concerns over U.S. scientific funding and infrastructure, particularly for Antarctic science, amid ongoing federal budget uncertainties.
