The Delta II First stage should be on the pad today!
Too much wind.
Now NET Friday.  Still too much wind.
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.

While not many news about the build-up of the Delta II, there are plenty about Dawn itself: it's got its solar panels in the process of being attached:

I knew the Dawn solar array would look big because of the artist depictions, but, damn, it's so much more impressive seeing it IRL. A shame we'll never be able to see a real view of Dawn after launch with its arrays fully deployed.
CGI pics still don't have the realism (and visceral impact) of *real* pictures.
(as an example: http://www.esa.int/esa-mmg/mmg.pl?b=b&type=I&mission=Rosetta&single=y&start=7&size=b )

Aeolus strikes again.  The next try will be Monday.  We've had strong winds off the Atlantic for 2 weeks now.

Why is the parabolic reflector black? Doesn't it heat horribly?

most deep space probes have black MLI to retain heat

How long can they delay the first stage erection before they have to slip the launch date? :o

STATUS REPORT: ELV-052507

EXPENDABLE LAUNCH VEHICLE STATUS REPORT

Mission: Dawn
Location: Astrotech Space Operations Facility
Launch Pad: 17-B
Launch Vehicle: Delta II 7925-H
Launch Date: June 30, 2007
Launch Time: 4:50:13 - 5:10:13 p.m. EDT

Solar array installation and deployment tests are scheduled to be
completed Friday.

The spacecraft is scheduled to move to the hazardous processing
facility on May 28. Xenon for the Ion Propulsion System is scheduled
to be loaded aboard June 1-2. Hydrazine, used for spacecraft control
and maneuvering, will be loaded aboard June 6.

The Delta II first stage, originally set for hoisting into the
launcher on Wednesday, has been rescheduled for May 28 due to high
wind conditions at Pad 17-B. This will be followed next week by
attachment of the nine solid rocket boosters.

Sorry to through us of topic but I keep wishing they would attach a faded rose next to the name chip ;)

Everytime I see this thread I start humming that song....

Delta II Dawn what's that payload you have on?
Could it be a faded rose from eons gone by?
And did I hear you say it was a launching you here today
To send you on a mission in the sky-eye
If you're happy and you know it,
It's your med's!

Can anyone say whether they erected the Delta first stage today?

I am aware that it's a holiday down there today, but the last I heard it had been resceduled for May 28th, today, so that's why I was wondering.

The crane at LC-17B has suffered a problem. One week hit to operations, potential hit to the launch date.

Article coming soon.

BTW, it just occured to me... has there ever been a Delta II mission with no solid boosters attached to the first stage? I mean, just the main engine?
No. Not a Delta II. Some old Thor-Delta varients did. Delta II only ever flys with 3, 4, or 9 boosters.

There's an excellent rocket genealogy here:

Notice where the Scout line merges with the Thor-Delta line.

Great link antares! I also never realized how much the vanguard gave way to so many different types of rockets.
