NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) spacecraft encapsulated inside SpaceX’s Falcon 9 payload fairings is transported from the Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida to Space Launch Complex 40 at Cape Canaveral Space Force Station on Thursday, Feb. 1, 2024, to be mated with a SpaceX Falcon 9 in preparation for liftoff set for no earlier than 1:33 a.m. EST on Tuesday, Feb. 6, 2024. PACE is NASA’s newest earth-observing satellite that will help increase our understanding of Earth’s oceans, atmosphere, and climate by delivering hyperspectral observations of microscopic marine organisms called phytoplankton as well new data on clouds and aerosols.
