Looks like we get more accurate/timely up to date info on the space program(s) here better than anywhere else...

However, in Spaceflightnow's Shuttle status report, there is word that they have scrubbed the launch.

Today's launch has been scrubbed.

Thanks hektor for the scrub notice. I' was out this morning looking for the con trail and figured it had scrubbed when I haddn't seen it by 1215z.  Any word on why they scrubbed?

Apparently a software-issue with the TacSat-2 payload

Indeed, scrubbed for today.  I was roughly 1/2 hour from WFF, (after 2 1/2 hrs on the road) when I found out :(  Apparently a software glitch with TacStar.  They are saying launch will be no earlier than Wednesday.  (I am hoping for Saturday) :)
I know only enough to know that I don't know....

As i  mentioned on Live spaceflight news thread, I was within 30 minutes of WFF when I heard of the scrub.  Sure made for a long boring ride back to Richmond :(

Thank god my wife put the kibosh on me taking a vacation day, packing my three year old, space crazy son, into the truck and driving the 3 hours down.  I'm opting to just watch the con trail from here in southern New Jersey.  You can see orbital launches out of Wallops from here as we're only 100 miles (as the crow flies).

My wife nearly did the same thing... should've listened ;) I dare say though, If the reschedule when I can make it, I'm just stubborn enough to try it again :)

This time though I'll call the info line MUCH sooner.....

Source info is there's a meeting at 10am local. An announcement at 2pm local.

Software issue with the payload.

This Minotaur might not make it off the pad this year now, according to this report.

http://www.delawareonline.com/apps/pbcs.dll/article?AID=/20061211/NEWS/61211002/-1/NEWS01

I wonder why this TacSat problem wasn't vetted until the last minute?  Surely this was an issue that was known by someone.

The following site provides some clues about what the problem might be.  TacSat-2 was built in a hurry using spare parts from a previous, canceled program.  The solar array design appears to have changed a bit during the development effort.

The orientation of the telescope also changed - by 90 degrees.  Note that the fixed portion (all?) of the solar arrays only get full sun exposure at "noon" during an equator crossing if the telescope is looking down at the Earth.  The original design appears to have been oriented for optimum use in a sun synchronous orbit, with fullest exposure at sunrise/sunset.

In addition, TacSat-2 was originally supposed to be launched on a Falcon 1.  I'm not sure what the originally planned orbit would have been.

"LAUNCH UPDATE: 3:30 p.m. 12/11/06:
The TacSat-2/Minotaur 1 launch set for today, Monday, Dec. 11, has been delayed with Thursday [Dec. 14] as the earliest possible launch date while a potential inconsistency in the TacSat-2 spacecraft flight software is being investigated. Analysis is ongoing. Information will be posted as it becomes available."

Until spacecraft are no longer in the realm of rocket science, tactical ops is a pipedream.  "Quick callup" is not compatable with the testing required of standard spacecraft.

Try to think 'Out of the BOX'; how would you get into the realm of tactical ops?
Well, you would accept a little more risk! And when you go low-cost, then you CAN assume more risk. I can think of a number of ways to get the spacecraft to orbit quickly.
This is a promising project that bears watching, if you have an interest in providing cost-efficient space vehicle services...

My company is interested in working with the provider of the solar array system for this vehicle, MicroSat Systems (their thin-film solar cell arrays could be a great new photovoltaic option). They look to be a very promising small, cost-efficient company. They were the systems integrator for this vehicle as well. I am hoping to see a successful mission.

No one wants to accept more risk.    More risk doesn't equate to cost effective.  There is a big difference in tactical and cost effective.
