This opportunity, part of NASA's Research Opportunities in Space and Earth Sciences (ROSES) omnibus announcement, solicits proposals for research under the Living with a Star (LWS) Science program. The LWS program focuses on scientific investigations that improve understanding of the Sun, heliosphere, and planetary environments, particularly their impacts on life and technological systems. Research areas may include solar variability, space weather, magnetospheric and ionospheric physics, and their effects on Earth's environment and society.
Proposals are accepted in a two-step process: all applicants must submit a Step-1 proposal by the due date; only those invited after Step-1 review may submit a full Step-2 proposal. Awards will be made as grants or cooperative agreements, with typical project durations of three years (some may be up to five years).
