NASA Explores Spacecraft Formation to Image Earth-like Exoplanets

NASA funds a study to investigate if two spacecraft flying closely could capture detailed images of distant Earth-like planets.

NASA has funded a concept study led by physicist Paul Stankus to explore the feasibility of using a pair of spacecraft flying in tight formation to capture images of Earth-like exoplanets. The proposed method aims to go beyond current capabilities that only detect distant worlds by producing actual images showing surface features such as continents and oceans. This early-stage idea is supported by NASA's Innovative Advanced Concepts program and represents a potential breakthrough in exoplanet observation if successful.
