Circular prograde orbit homework

[QUOTE="ExoP, post: 4515777, member: 486812"] [h2]Homework Statement [/h2] Hi! I have a problem with an assignment and need som help. The question is: You’ve just completed an analysis of where the Space Shuttle must be when it performs a critical maneuver. You know the shuttle is in a circular prograde orbit and has a position vector of: ro= 6275.396Î + 2007.268J + 1089.857K. In 55 minutes, you predict the orbital parameters are : a = 1.0470357ER ,e = 0.000096, i = 28.5 degrees , M = 278.94688 degrees Comments: The initial orbit is circular, but the final orbit has eccentricity different from 0, but it is small, perhaps caused by disturbances. Is your analysis correct? Answer with either of the two beginnings: a) The analysis can’t be correct, because …. b) The analysis is correct, provided that periapsis has been created at ….. How should I tackle this problem? I really don't have an idea where to start. Should I use the values given and then decide if it is a circular prograde orbit or not? That is my thought. Thanks!
