Not directly, because the launch time is chosen to correspond to the position of ISS' ascending node, ie -27 min/day. In orbit, STS has the same longitude also has the same longitude 27 minutes earlier in next day's orbit. But ISS makes 15.8 orbits/day, so it is +21/-72 min/day, and the approach sequence must be different. However, in two days STS should be -54 min (early) and ISS -51 min, so you might make two approximately similar tables for odd/even dates. /Björn ----- Original Message ----- From: "Dale Ireland" <direland@drdale.com> To: "'Ted Molczan'" <seesat-list@rogers.com>; "SeeSat-L" <SeeSat-L@satobs.org> Sent: Sunday, August 27, 2006 6:56 PM Subject: RE: STS 115: estimated MECO elements > Hello > Is the time difference between the ISS and the Shuttle the same after a > certain period after launch even when the launches are rescheduled? > In other words, can you say that 3 hours after launch the STS will be > following the ISS by 35 minutes +/- 10 min (or whatever the launch window > is) and 12 hours after launch it will be leading by 15 minutes and 24 > hours > after launch it will be leading by 5 minutes etc etc. > Or does the rescheduling of a launch by a day or two totally change the > approach maneuvers? > So is it possible to make a little table with, roughly estimated ISS-STS > visual pass time difference vs. hours after launch, so one doesn't have to > hunt for the element sets to see STS? > > Dale > > > ------------------------------------------------------------------------- > Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: > http://www.satobs.org/seesat/seesatindex.html > ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
