It’s been 40 years since the launch of STS-1, and the excitement of that day never faded.
The verb tense in the sections below, then, are still “active”, as that’s the way the FDO and the entire space program was when I wrote them. I do not want to change them, as I still believe that we will, as a nation, realize the short-sighted nature of recent national policy decisions and revitalize our efforts.
Hopefully one day soon, the FDO and the ever-present container of Atomic Fireballs, will once again be front-and-center in the Mission Control Center.
But for now – here’s what the FDO *used to do* during Space Shuttle missions…
The Flight Dynamics Officer (FDO, pronounced “fido”) is responsible for the overall trajectory, or flight path, of the Space Shuttle and all related payloads or other space-bound vehicles associated with the Shuttle.
The FDO is a Mission Control Center Flight Control position at NASA’s Johnson Space Center. There, along with other talented and dedicated individuals, the FDO ensures that the “big picture” mission objectives are obtained.

The Ascent FDO goes from launch pad to space.

The Orbit FDO makes this look easy.

The Entry FDO makes it happen!
