Filed under ,

NASA’s Advanced Information Systems Technology (AIST) Program identifies, develops, and supports adoption of information systems expected to be needed by the Earth Science Division in the next 5-20 years. This AIST call for proposals focuses on technologies and innovative concepts that enable 3 main objectives:


O1.   New observation measurements and new observing systems design and operations through intelligent, timely, dynamic, and coordinated distributed sensing;

O2.   Agile Science investigations that fully utilize the many and diverse observations using advanced analytic tools, visualizations and computing environments, and that interact seamlessly with relevant observing systems;

O3.   Integrated Earth Science frameworks that will mirror Earth Science systems with state-of-the-art models, timely and relevant observations and analytic tools that will enable near- and long-term Science and policy decisions (“science decisions” include acquisition of new measurements, development of new models or science analysis, new data assimilation or fusion, etc.)


ROSES-2021 Amendment 25 releases final text and due dates for A.46 AIST, which was previously “TBD”. Step-1 proposals are due August 25, 2021, and Step-2 proposals are due November 30, 2021.


On or about July 2, 2021, this Amendment to the NASA Research Announcement “Research Opportunities in Space and Earth Sciences (ROSES) 2021” (NNH21ZDA001N) will be posted on the NASA research opportunity homepage at and will appear on SARA’s ROSES blog at:
