Community Meeting to Discuss a White Paper in Support of a CMB Space Probe

We have a unique opportunity to advocate that a CMB Probe mission be studied in preparation for the Astro2030 Decadal Survey through the ASTRA Initiative. See more details on the ASTRA webpage. NASA is requesting community input on which 4-6 missions (plus far-IR and X-ray flagships) should be studied. NASA plans to announce the selected missions at the January 2027 AAS meeting. In advance of that, there will be the AD ASTRA community workshop in Pasadena, CA, in early September. We need strong advocacy from all of you to emphasize the importance of a CMB mission to NASA.

Over the years, CMB data generated in space has transformed astrophysics, and the case for a fourth CMB space mission is strong. Since Astro2020, much has changed in the CMB landscape and the White Paper being written by the CMB SAG will survey what has changed and how the community recommends that NASA move forward. We will discuss topics to include in the white paper and give updates on the preparations at NASA for the mid-Decadal review.
