I have produced an MS Excel spreadsheet to compute azimuth, elevation, R.A. and Dec, and an indication whether the shuttle is in sunlight, or the umbra or penumbra of Earth's shadow, during STS 128's ascent to orbit on its mission to ISS: http://satobs.org/seesat_ref/Shuttle/STS_128_Ascent_Trajectory_to_ISS.xls To use, enter your observation site co-ordinates and the date and time of lift-off, in the specially labelled cells (those with red coloured font). The spreadsheet is set up for STS 128's scheduled launch on 2009 Aug 26 at 05:36:05 UTC, as seen from Washington, D.C. I obtained the trajectory data from The CBS News Space Reporter's Handbook, by William Harwood: http://www.cbsnews.com/network/news/space/downloads.html Scroll down to the SpaceCalc section, and see file SpaceCalcPC_128.zip for PC or SpaceCalcMac_128.zip for Mac.
