[Orekit Developers] Re: [Orekit Users] Orekit 6.0 released

[Michael Turner <michael.eugene.turner@gmail.com>]

I have a Basecamp project, Integrate Orekit into SpaceNet. The lead on
SpaceNet, Paul Grogan at MIT, has generously offered some comments on
the implications of the proposal.

  https://basecamp.com/2318622/projects/3363257-integrate-orekit/messages/13897293-greetings-all

I like his comments very much, not only for their obvious detail and
apparent cogency, but also because they suggest action items.

I am no orbital mechanics expert, but some of you must be. Please let
me know (private e-mail is fine) if you'd like to be added to this
project. My bar for what constitutes teamwork is quite low: you'll be
thanked if, at the very least, you comment in a thought-provoking way
(or action-provoking way) on what Paul has written.

If you'd only like to keep an eye on this project, I can add you to
the list, "The Client". Feel free to request any features you'd like
to see in an Orekit demo app, so long as they are plausibly
logistics-related. These requests, and their resulting code, might
feed into the SOCIS 2013 effort on Orekit.

If you know enough of the internals of either Orekit or SpaceNet to be
a developer, and can even /consider/ contributing to their
integration, I'll be happy to add you to Team.

Please specify Client or Team, in your reply. But don't feel bound to
one role or the other just because that's the one you started in.

Regards,
Michael Turner
