Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) is a NASA Earth-observing satellite mission that will continue and advance observations of global ocean color, biogeochemistry, and ecology, as well as the carbon cycle, aerosols and clouds.[3] PACE will be used to identify the extent and duration of phytoplankton blooms and improve understanding of air quality.[4] These and other uses of PACE data will benefit the economy and society, especially sectors that rely on water quality, fisheries and food security.[5]
After being proposed for cancellation under President Trump's FY 2018 budget, it was restored by Congress.[6] The PACE project is managed by NASA Goddard Space Flight Center.[7] The main instrument and bus were designed and built at Goddard Space Flight Center.[8]
On 4 February 2020, NASA announced the selection of SpaceX to launch PACE on a Falcon 9, at a total cost to NASA of US$80.4 million, including the launch service and other mission-related costs.[9] The total cost of the mission is $964 million, which includes spacecraft construction, launch, and operations.[10] PACE successfully launched on 8 February 2024 at 06:33 UTC.[11] On 17 April 2024 it was announced that first operational data was received.[12]
