Hi All,
Graeme here with a first post on Space.com.
I'm an old fart who saw the first moon landing stuff on a black and
white TV in grade school.
Decades later I'm here looking for some sort of computational
orrery(sp) that I can query regarding various things like planetary
characteristics as well as satellite trajectories and masses.
Is anything like that publicly available?
