Second stage fueling has been completed.
Launch weather outlook is favorable with a 30% chance of violation. -------------------- |

QUOTE (mars loon @ Sep 24 2007, 02:39 PM)  Hey Tom, thanks for the citation. yeah the weather was quite awful down here today. thunder and buckets of rain. hopefully better tomorrow ken I could see during the conference that you don't call yourself "mars loon" for nothing : good question about science at Mars... and the one about life too. I hope you've got a better answer by now on this one than during the conference ! Thanks Ken -------------------- |

If someone's interested I've made a quick and dirty animation of the Ceres images obtained by Keck to today's spacEurope post about the mission.
I'm sure someone must have already done similar and with better quality by I couldn't find it. We haven't leave the ground and I can't already wait to get there...

The Mobile Service Tower has rolled back... The Delta II is now completely out in the open.

I noticed the timeline after launch in this blog entry says the groundlit SRBs are jettisoned at T+1 min 20 s. Most of the Delta II launches I saw had the boosters separated right after burnout, at 65-ish seconds, but a couple of them held on to the groundlits longer. What's up with that?
Seems like carrying deadweight for no reason. Is this one of those booster disposal considerations similar to those weird dogleg maneuvers after sep? -------------------- |

"but a couple of them held on to the groundlits longer. What's up with that? "
I THINK they said in the prelaunch briefing that they're bigger strapons that burn longer. this is a Delta-II heavy. Another interesting thing in the briefing was a response to a question about science during the mars flyby. They will do a full science run, but only at and after closest approach. The approach to Mars is from the nightside at a 160 degree phase angle... extremely narrow crescent 20 deg from the sun. |

Any recent news regarding the weather?
I've receive an e-mail from Chris Russell, Dawn's PI, about this: "Everything is AOK here (at Kennedy Space Center) except, as usual, the weather is wet on and off and we will not know if we have the conditions that permit launch until tomorrow (today) morning at 0720 EDT (1240 UTC - 0240 HST)". This was already 9 hours ago, any developments? -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"

QUOTE (edstrick @ Sep 27 2007, 10:07 AM) I THINK they said in the prelaunch briefing that they're bigger strapons that burn longer. this is a Delta-II heavy. That would make sense, but there's still for example this video (ffwd to 03:40). Granted, this was a Vandenberg launch so it was likely a booster disposal thing. Coincidentally, that's one of the best RocketCams I've seen on a Delta II - excellent video quality, but the rocket executed the weirdest maneuvers ever. I wonder how much maneuvers like that affect payload capacity. -------------------- |

QUOTE (ustrax @ Sep 27 2007, 10:20 AM) 9 hours ago, any developments? Just in: The launch time weather forecast continues to predict scattered clouds at 3,000 and 10,000 feet, isolated rain showers in the area, northerly winds and a temperature around 77 degrees F. There is a 60 percent chance that weather will be acceptable for liftoff this morning. The cloud cover and showers are the concerns. Should the launch be delayed to Friday for any reason, tomorrow's weather outlook calls for an 80 percent chance of good conditions. -------------------- 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.
