At some point, I expect official planned elements to be available via this page: http://spaceflight.nasa.gov/realdata/sightings/SSapplications/Post/JavaSSOP/orbi t/SHUTTLE/SVPOST.html In the meantime, appended are my estimates, assuming lift-off as scheduled, on 2005 Jul 13, at 19:50:52 UTC. The MECO orbit is for the benefit of European observers, who will have a pass near their sunset, less than 20 min after launch. It is derived from the pre-launch elset I provided for STS 111, which proved to be very accurate, based on observer's reports. Care should be taken to use the elements only within the stated date/time limits. Use the NC-1 orbit for the shuttle's passes over North America. I obtained the time of the OMS-2 and NC-1 burns, and the post NC-1 orbital dimensions, from Bill Harwood's SpaceCalc flight plan, available in spreadsheet form on his site at CBS News: http://cbsnews.cbs.com/network/news/space/SpaceCalcPC_114.zip and in html at Spaceflight Now: http://www.spaceflightnow.com/shuttle/sts114/fdf/sts114plan.html Ted Molczan I expect the following elements will be accurate to well within 1 minute of time, within the stated date/time limits. Of course, it can't hurt to allow for a few minutes of error. 1.
