Science Interest Group
Inflation Probe
The Inflation Probe Science Interest Group (IP SIG) will provide quantitative metrics and assessments to NASA with regard to a future Inflation Probe mission. The IP SIG is open to the scientific community.
About IP SIG
Updating Mission Science Goals and Assessing Necessary Technology Developments
The Inflation Probe SIG will review and update mission science goals following current developments in the field.
IP SIG will review and update information about and requirements on potential foreground contaminants and their removal. IP SIG will also review and update requirements on and developments in control of systematic errors, and will assess necessary technology developments and prioritize areas for increased technical emphasis.
A new CMB SAG, initiated in December 2025, will evaluate the role that a future Cosmic Microwave Background space mission would play in addressing fundamental questions about our universe.

The IPSIG was pleased to submit the White Paper, CMB Polarization Measurements: 2015 and Onward (August 2014), that summarized the current situation with B-mode measurements and provided our perspective for progress over the next several years. This white paper benefited from contributions by many within the CMB community both in the US and abroad. It had been discussed in two open telecons, undergone revisions to reflect concerns and inputs, and iterated upon by e-mails several times. It represents the outcome of a community-wide open, collaborative process.
