Re: [Utah-astronomy] Picture in the DN
Jim, Upon closer examination, there are many stars you caught in your image as well. Identifying these stars will give a VERY precise position of the shuttle when you shot your image. BTW, the compression ratio of your image is 19:1. Brent --- Jim Gibson <xajax99@yahoo.com> wrote:

Thank you. You deserve a grate deal of credit for the pictures we all got. You got us in the right place at the right time oriented in the right direction with the right setup. All I did was push the button.
The one thing I kick myself for now is that I didnt have my date/time stamp turned on. After working for 17 of the last 27 years in the data collection business and in particular being involved in writing programs that bring a number of different data sets together for analysis, I know how important it is to have properly time coordinated data. With out it the significance of each data set is reduced. It would be easy to assume that the video shown on TV and my picture are data of the same event. There is a good chance that that is not the case. If anyone hasnt seen the video spoken of shown on KSL go to
http://tv.ksl.com/index.php?nid=39&sid=8498
If we consider that the zipper affect started over Hawaii, pieces were falling off over the pacific, California, Nevada, Utah, Arizona etc all the way to the final catastrophic event. There were multiple events and without time coloration it makes it very difficult to have confidence in saying these two pictures were of the same event. Patrick from some of your previous statements I feel that the event I captured was of the 6:56 (local time) event. Saying I feel does not inspire a lot of confidence in an important matter. You were astutely the timekeeper besides everything else you were doing. I guess the best we can do is say here is our piece of data.
Just a few thoughts concerning me.

. All that got me was "Not Found The requested object does not exist on this server."
Has anyone been able to get to Jim's picture today?
BTW, kudos to Jim for a fine interview on KSL TV this evening.

Brent In reference to the recorded time on the Columbia event picture - I took a picture of our IRIG clock at 07:16:29:00 UTM. I converted to local time by subtracting 7 hours: 09:29:00 Local. Then I looked at the header information on the camera and it recorded: 10:53:10 The difference is 1:24:10 The critical Columbia picture has a recorded time of 8:19:38 and when I subtract 1:24:10 from that I get 6:55:28 Local time when the shutter was open. The time reported for the problem in the wheel well I believe was 7:56 Huston or 6:56 AM (local time) This now can be reliably correlated with other time series data to add to a growing picture. I took three pictures and recalculated the time for each Recorded time Actual time 08:19:18 06:55:08 Orbiter approaches 08:19:38 06:55:28 Orbiter over head 08:20:06 06:55:56 Orbiter rides off into the sunrise No wonder I thought it happened fast; it all lasted less than a minute Jim --------------------------------- Do you Yahoo!?

Does anyone know if a launch vehicle has been selected for the James Webb space telescope? (NGST) Last I heard, it was still a toss-up between 2 or 3 different disposable vehicles, and a modified shuttle....thinking here that the loss of Columbia will probably affect that decision. Patrick, what do your NASA connections say? Will the NGST be delayed because of the shuttle loss? And a related question: Will one of the remaining shuttles be risked to return the Hubble to earth when it's mission is terminated? I had read of the possibility of it going on-display in the National Air & Space Museum. Sorry if these questions are naive; I'm not a dedicated follower of the space program.

I don't have any contacts at NGST. However, I did have a look at their web site. It's not been updated post-accident however, question 13 of the FAQ ( http://ngst.gsfc.nasa.gov:80/FAQ/FAQ.htm ) addresses the question pre-accident.
Will the NGST be delayed because of the shuttle loss? A contact at KSC sends me something called "Spacecraft and Expendable Vehicles Status Report" every couple of days. Looking at today's issue, it looks like all of the non-shuttle related launch dates remain unchanged.
And a related question: Will one of the remaining shuttles be risked to return the Hubble to earth when it's mission is terminated? I had read of the possibility of it going on-display in the National Air & Space Museum. Pre-accident, that was the plan. And I, for one, look forward to seeing it on display one day.
Obviously I can't speak for NASA but everything I've seen coming out of NASA post-accident indicates the plan is to get STS flying again ASAP. I've seen no mention of any changes to previoulsy planned shuttle activities.
