PACE Polarimeter
[06-Feb-2024] The PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission will continue and improve NASA's 20-year record of satellite observations of global ocean biology, aerosols, and clouds. PACE will help us better understand how the ocean and atmosphere exchange carbon dioxide, measure key atmospheric variables associated with air quality and Earth's climate, and monitor ocean health, in part by studying phytoplankton, tiny plants and algae that sustain the marine food web.

 Study Contract Proposals Received
 ACCP Project Authorization Letter (PAL) Received
[23-May-2021] The ACCP Project Authorization Letter (PAL) has been received. This authorization signifies the transition from Project Formulation to Implementation.
[05-Feb-2021] The ACCP Architecture Recommendation Review has been released. These architectures provide multiple breakthrough technologies that will answer fundamental questions about how microscopic particles interact in the atmosphere to fuel severe storms, impact air quality, and influence our changing climate.
 Concurrent Design Center Studies #1-#4 Completed
[20-Aug-2020] These studies provided Large, EELV Secondary Payload Adapter (ESPA) Grande, and ESPA Class Spacecraft designs used to accommodate ACCP instrument suites of various sizes and capabilities and the accommodation of a Japan Aerospace Exploration Agency (JAXA) Ku Band Doppler Radar. The two remaining Collaborative Design Center Studies will focus on Mission Operations and Ground System Architectures including Science Data Processing, Distribution and Archival (July 2020) and Refinement of Architectures (October 2020).
 Architecture Construction Phase Nearly Complete
[03-Aug-2020] The Architecture Construction Phase is nearly complete (Architecture Freeze Planned for September 2020).
