Amendment 15: Space Weather Science Application Research-to-Operations-to-Research Text Length Increase and Due Date Extension.

The primary goal of the Space Weather Science Application Research-to-Operations-to-Research (SWR2O2R) program is to support research to improve numerical models and/or data utilization techniques that could advance specification and/or forecasting capabilities and which could also lead to improved scientific understanding.

The two application-oriented areas of focus for this opportunity are:

Cis-Lunar Environment Forecast: Develop improved space weather application models and operational forecasts for the cis-lunar domain as it pertains to increasing government and commercial activity and Solar Flare Activity Forecast: Improve the skill of short-term, probabilistic flare forecasts based on currently observable inputs as they pertain to direct (ionosphere) and indirect (CMEs, SPEs) events that directly impact the geospace environment and impact deep space exploration.

ROSES-2021 Amendment 15 increases the length of the page-limited S/T/M Section for proposals to B.7 SWR2O2R from 10 to 12 pages and the due date has been delayed. Step-2 proposals are now due June 10, 2021.

On or about May 6, 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
