Early WX balloon run of the Overpressure safety criteria (which was marginal on Wed) was reported as "good."  It's the last balloon before launch that counts, though...

Just got WX briefing.  As far as basic constraints are concerned, the POV is 10% today and 35% tomorrow.  Problem with upper level (35K-40K) winds - unusually strong jet stream.  We are evaluating.

Yes, very appreciated.  POV is probability of violation [of constraints]?

Yes.  But that's only the "hard" range criteria (including some that come from us.)  There are also the high-altitude winds, which are more of a qualitative call than hard values.

Our dilemma is the wind shear around 20K produced by the strong jet stream: the trajectory (we can choose from a small set sometime around T-45) that lowers the loads on the vehicle also bring us uncomfortably close to the North destruct line.  Paul Baumgartner and Tracy Chisholm are running trajectories as we speak. They will have to make a judgement call on the traj, and then Mission Director will have to make a go/no go call from that.

Oh, well, TANSTAAFL...

Well it's not surprising that the jetstream is very strong behind such a big squall line (?) system... let's see what will happen by then.

 :o Newbie warning alert!  :o

The Jet Stream looks strong over the launch site now.
http://images.intellicast.com/WxImages/JetStream/conus.jpg

The surface winds map is here.
http://hint.fm/wind/

What are the limits on both surface winds and winds aloft that would prevent launch?  I know there are probably aircraft aloft giving ground controllers weather information up to say 40k ft...Are they also launching balloon after balloon to get upper atmosphere data?

Edit - Oh, another question:
I cannot find (yet) information on the weather briefing for this mission and a percentage given towards launch probability based upon weather, etc...  Does anyone have that info?

Getting ready to drive up there in an hour!

Thanks

Winds aloft are never discrete limits for any vehicle.  There are day-of-launch calculations done to determine if a vehicle can steer through the wind shears without tumbling and without exceeding structural limits.  Theoretically, a strong-enough headwind could create enough additional drag that the vehicle could not make its performance targets.  That would be a very marginal case with a payload that needs every last pound of performance, or where another factor contributing to low performance would compound the problem and cause the mission to come up short.
If I like something on NSF, it's probably because I know it to be accurate.  Every once in a while, it's just something I agree with.  Facts generally receive the former.

L-5:30 balloon data showed us red on debris field (strong mid-alt southwesterlies) I wonder if we shouldn't delay to the latter part of the 2-hour window to let the mid-alt winds settle a bit... that could help the other issue, too.

Am I right to recall that a decision to delay into the later part of the window must occur prior to LOX load (T-90)? Or is it at commencement of pre-chill (T-180)?

How is it implemented?  Extending a built-in hold?

Decision to launch at a nominal time other than the beginning of window must be made before beginning of propellant (RP and LOX) loading or L-1h30m.  After than, the variability is limited to +15m - 0m

No "built-in hold" - simply delay beginning of loading phase - everything else can wait with no adverse consequences.

Range is trying to relocate some 40 or so people from the extreme south end of Assateague to clear additional people-free space because of the strong southwesterly winds... if they are successful, AND the FAA approves the new debris limit lines, we MIGHT be able to launch today...

If they do it, it would be the most awesome real-time reprogramming I've ever seen a range do...

I guess they will tell them that either they move back or the will NOT see a launch...

Here's plan: we moved T0 by 10 minutes (5:10 EDT) to allow us to evaluate the 3:30 EDT balloon debris field data - if OK we'll proceed to fueling.  If not, we will delay to 6:10 launch and repeat the eval at 4:30 for a 7:10 launch or scrub.  We're in the process of coordinating this with the balloon guys...

Yup - red on debris.  Try for 6:10, make a decision around 4:40.  Altitude winds for tomorrow 20-25 knots lower than today... today was an extraordinary day for the 15K to 35K altitude range (105 to 120 knots - normal is more like 65 to 80 knots, and much fuirther from the pure west)

Folks: not looking too good - winds are NOT trending (last few balloons right on top of each other) PLUS as we go into the window we use our LOX ... if we go to the 7:10 opportunity we may not have enough LOX to use the full two-hour window tomorrow ... Frank C. chewing on it... since tomorrow's challenge will be surface winds, we probably want the ENTIRE window tomorrow ...

Just got the Overpressure and Toxic evals from the last balloon - both green ... debris in a few minutes ...

Thread is now open for specific discussion relating to this attempt, because we'll have a new thread on Sunday.

Tomorrow POV 25% overall ... dominated by surface winds now forecasted for 12 to 17 knots form the SE ... altitude winds 20 tp 25 knots lower than today

Booo! These are the first launches (well, attempts) I've ever watched from Wallops...and both times winds were creating issues. I'm no weather expert, so does Wallops being further North than KSC generally increase the chances of high winds (or bad weather in general)?

wait.... Scrub just because 40 people were too close? Not homes / wildlife sanctuaries,etc, but human tourists too close?  If so, wouldn't the initial allowed observation range have been set  further out from the get go?

It would be nice to have some clarification whether these were people who went closer than the perimeter set by the USFWS at Chincoteague NWR.  See http://forum.nasaspaceflight.com/index.php?topic=31517.msg1039079#msg1039079

No, that had to do with an attempt to extend the range area based specifically on today's conditions.

No, just an unseasonable Winter cold front one month into (Northern Hemisphere) Spring.  Don't worry, lawyers here are already taking it up with Punxsutawney Phil.

Right, but, probably just (understanably) simple lack of tourist history that _initial_ allowed observation range wasn't _already_ initailly set at the " 99.9% chance no problem" level vs, say merely some "99% chance no problem level", or such?

And, I guess FAA proper is official entity that decides. ?

The range does.

Well, not bad weather in general. Florida likes lightning ;)

But yes the jet stream is generally near if not overhead the Mid-Atlantic states, and the subtropical jet stream closer to Florida is not nearly as strong.

ORBITAL RESCHEDULES NEW ANTARES ROCKET LAUNCH WINDOW 

– A-ONE Mission Team Working Toward an Attempt on Sunday, April 21 –

(Dulles, VA 20 April 2013) – Orbital Sciences Corporation (NYSE: ORB), one of the world’s leading space technology companies, today announced that excessive, high-altitude wind speeds prevented the planned April 20 launch attempt of the Antares rocket from the Mid-Atlantic Regional Spaceport (MARS) launch pad at NASA’s Wallops Flight Facility on Wallops Island, Va.

“Given the winds and wind direction, the debris requirement for the Range and Federal Aviation Administration could not be achieved today,” said Mr. Frank Culbertson, Orbital’s Executive Vice President and Mission Director for the Antares Test Flight. “This requirement keeps any potential debris from falling outside of a predefined area in the event of an anomaly. Flight requirements dictate that we stop the countdown and pick it up when the conditions improve.”

The next launch attempt is scheduled to take place no earlier than Sunday, April 21, with a window extending from 5 - 8 p.m. EDT. NASA TV and webcast launch coverage will begin at 4:30 p.m. EDT on www.NASA.gov.

Hard luck but a valiant effort! Thanks to OSC folk for the great updates, and good luck tomorrow.

edit: moved crazy question to party thread :)
