| The NASA Earth Science Division Airborne Science Program Annual Call Letter serves as a notification for the opportunity to request airborne science flights for the upcoming fiscal year. The call letter is released several months prior to flight requests being due for the upcoming year.
New flight requests can be submitted at any time but it is strongly recommended that Principal Investigators submit a request by the deadline to ensure that the program can accommodate their request(s). Please note that flight requests can be submitted as placeholders to be updated at a later date. |
