"Unusually uncooperative weather in Alaska"?
They were expecting sunny skies and warm breezes in the Aleutians in February/March?

Live video of the frosty rocket venting.
Still no launch time to announce.

edit: 700 lbf upper stage named 'Ether' or 'Aether'.

What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

I thought I recognized that voice. The webcast host is Mike Curie, is he not with NASA any more?

Chris Thompson, who is the launch director for today's Astra mission, was also the launch conductor for the Falcon 1 rocket's first flight back in March, 2006.

Ironically, Astra is looking at Kwajalein Atoll as a site for equatorial launches. Among the islets they have surveyed is Omelek Island, where the Falcon 1 launched from five times. I asked Chris if he was looking forward to returning to Kwaj. His response: "Not really."
