 Concurrent Design Center Studies #1-#4 Completed
[20-Aug-2020] These studies provided Large, ESPA Grande, ESPA Class Spacecraft designs used to accommodate ACCP Instrument Suites of various sizes and capabilities and the accommodation of a JAXA Ku Band Doppler Radar. The two remaining CDC 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).
[05-Jan-2018] The National Academies of Sciences, Engineering and Medicine's 2017 Decadal Survey, Thriving on Our Changing Planet: A Decadal Strategy for Earth Observations from Space, highlighted Earth System Science themes, science and application questions, and several high priority objectives that led to the inclusion of ACCP as a Designated Observable observing system.
