Although we did our best to reach page 14 ... a redline monitor fault had other ideas
 By The Way ... still no " New Horizons " items here: http://www.bookstore.caltech.edu/jpllab/de...NK11FR6W2SHAC9A Safing the vehicle now

QUOTE (dvandorn @ Jan 17 2006, 12:21 PM) OK, what's the launch window for tomorrow? I know, the weathre doesn't look all that good, but... -the other Doug  report from early today was 60% for violation of launch criteria. |

I think I just learned that I don't have the temperament to be a launch controller. Those guys just look so calm and cool, and I'm about ready to jump out of my skin.

Welcome to the space business...
We still have a healthy Atlas V and NH. The hardware looks in great shape. Tomorrow's launch window extends from 1:16 to 3:15 p.m. EST. See you then.

I HATE WINDS!!!
The constraint that violated a red line limit was indeed the ground winds. There was a gust that broke the 33-knot limit as the countdown was proceeding to a last-ditch attempt for launch at the very close of today's available window. -------------------- The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.

Would it have been better to launch our rockets in the Southwestern desert like they used to in the 1940s and 1950s? Look at those old artworks of "future" space missions. Most of them are launching from a desert locale. -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

QUOTE (YesRushGen @ Jan 17 2006, 08:24 PM) Looking to this table, I understand the reson of the delay if we miss Jupiter assist. What is not clear is why there are further huge slippages in February (1 year every 3/4 days of delay!). It seems that a small shift in start position imply an heavy change, peraphs due to a more elongated orbit... am I correct? can someone simulate this? -------------------- I always think before posting! - Marco -

It seems that a small shift in start position imply an heavy change, peraphs due to a more elongated orbit... am I correct? can someone simulate this? My reasoning is that because Earth moves in its orbit much faster than Pluto, during a course of 3 days it covers an arc around the sun of a few degrees. If the launch speed and eject trajectory always stayed the same, it would mean that the arrival point at Pluto would also be shifted by the same angle. However, Pluto takes a whole lot more time to cover that angular distance so you actually need to launch slower than you theoretically could, just so you end up at a precise point in Pluto's orbit exactly when it's there also. But then again, a slower inital launch introduces yet further delays and it's a closed circle. One Pluto's orbit takes 248 Earth ones so a quick and dumb estimate yields 248 days of arrival delay (for Pluto to arrive at the new arrival point, not actual arrival at Pluto!) for each day of launch delay. Obviously this wouldn't work very well. This is purely theoretical and a very big simplification of the whole scheme. Of course, a powerful booster like the Atlas V obviously can cut some corners here and there. -------------------- |

The chance of the weather srubbing the launch on Wednesday is currently set at 30% (today, Tuesday was set at 20%). Thursday's chance of a scrub due to weather is only 10%.

I'm expecting New Horizons to launch on Thursday...according to the forecast on Yahoo.com
