I have converted JPL geocentric data to SkyMap 'Rocket Trajectory' .trj files, which avoids getting topocentric data for each observer. Just run SkyMap with F5 rocket option, F7/F1 to one of my .trj files, and set time to 05:00 UTC 2003/06/29. I made a test run for the Delta rocket post-depletion burn and one for MER/B (opportunity 1) using Don Gardner's coordinates. I get a pass just below alpha Oph at 05:32, range 5924 km, two deg below zet Aql at 05:43, and a nice U-turn at Altair at 06:17, range 22382 km, returning to Ophiuccus (beta) 09:19 79862 km. For Austin, TX, it is closer to delta Herc 05:26:30, and the U occurs before passing Altair.
