We have a team of 7 right now. We anticipate adding 1 other person and possibly added 1 to 2 others part time.
With regard to the division of labor, everyone has a full plate. From rocket to balloon to payload to tracking to orbit insertion to motor, we have a lot to complete in relatively little time, two years. My tasks are project management, orbital mechanics method/implementation and help on all other aspects as needed.
When we get the website up, hopefully in about two weeks from today, we'll try to have some more info concerning the team.
