1st years will hear more about fellowships in 6949. 2nd years: Note this year’s deadlines for NSERC, NSF, NDSEG fellowships, which some will be eligible for:
NSERC (Canada) – 15 Oct
NSF (US citizen/perm res) – 29 Oct
NDSEG (US citizen or national, NOT perm res) – 12 Dec
The deadlines for NSF and NDSEG have both moved about a week earlier than last year. I have some summary info at https://gradhandbook.mae.cornell.edu/graduate-fellowship-information/
3rd year and beyond: this is probably irrelevant, can discard
