Advice for non-NSF fellowships?

[starmaker]

So, there's plenty of detailed advice out there for NSF GRFP applicants. But I haven't been able to find much for other major STEM fellowships.

There's Philip Guo's fellowships advice page (which covers NSF GRFP, NDSEG, and Hertz, but mostly focuses on the NSF) and the SMART Forum (for SMART fellowship applicants). But I haven't found anything specific to the NDSEG or Hertz, and I haven't found anything at all for various other major fellowships - the NPSC, the DOE CSGF, the various NASA fellowships, etc. These are big-deal fellowships that get lots of applicants, so it surprises me that there's nothing out there. Maybe my Google-fu is lacking.

Does anyone know of any advice resources for the other, non-NSF, STEM fellowships?

There's so much advice for NSF GRFP because NSF GRFP gives out that advice itself. Also, every application is returned with a review of strengths and weaknesses. Neither of these occur with NDSEG, Hertz, etc.
