The NESSF fellowships are available in Earth science, heliophysics, planetary science and astrophysics. Students admitted to, or already enrolled in, full-time M.S. or Ph.D. programs in Earth science, space science or related disciplines at accredited U.S. universities are eligible to apply.
The NESSF program solicits research involving data collected by space-based instruments during current and past NASA missions, relevant ground-based data and laboratory experiments, and theoretical modeling. Investigations that support instrumentation development relevant to future missions are also encouraged.
