Where do I find those? Gerhard, Both the Re-entry capsule , and the rest of the spacecraft are objects available from JPL Horizon system at http://ssd.jpl.nasa.gov/horizons.html This system has web, telnet and e-mail interfaces. The e-mail interface is the most flexible and biggest learning curve. However the web interface allows ra dec and distance from the geocentre so a little extra caculation gives geoecentric cartesian, if thats what you want, or just use two vectors to calculate geocentric hyperbolic orbit.
