New NASA chief scientist pledges a plan to renew agency’s Earth satellite fleet

NASA’s newly appointed science and Earth science lead says there is “more to plan” when it comes to figuring out next priorities for the agency’s aging satellite fleet.

Katherine Calvin is the first NASA chief scientist to also act as the agency’s senior climate advisor, a role created in February 2021. Calvin is serving in the roles under a temporary assignment from her long-time base at the Pacific Northwest National Laboratory’s Joint Global Change Research Institute. Calvin comes to the agency as NASA works to implement a new Earth System Observatory, first announced in May 2021. The program intends to send a set of Earth-focused missions to space to document climate change and facilitate responding to the crisis.
