CIBER-2 (Cosmic Infrared Background ExpeRiment) is a near-infrared rocket-borne instrument designed to conduct comprehensive multi-band measurements of extragalactic background light (EBL) anisotropy on arcsecond to degree angular scales. CIBER-2 builds on the successful measurements and proven methodology of the predecessor CIBER-1 instrument. This is a reflight of CIBER-2, flown on April 16, 2023 from White Sands Missile Range, NM. No science was collected on the April 16 flight, due to termination of flight shortly after launch.

The Principal Investigator is Dr. Zemcov/Rochester Institute of Technology.
