This $69,997.45 federal grant was awarded by the National Aeronautics and Space Administration (NASA) to The Trustees of Columbia University in the City of New York, operating as Columbia University through its Sponsored Projects Administration Division. The grant supports research on how planetary characteristics and environments change dramatically over their lifetimes, particularly during the first few hundred million years. This is a valuable area of study as most known exoplanets are older and have poorly constrained ages, making them less suitable for investigating planetary evolution. The grant does not have a set-aside designation and was awarded on February 27, 2019, with a period of performance ending on February 26, 2021. Columbia University is a renowned private research institution with extensive experience conducting government-funded scientific research across numerous disciplines, including space science, under both contracts and grants.
