Guys, I figured it out. Here's how we can make everything work out between the conflicting launch of Dawn to the asteroids and Phoenix to Mars. It's a brilliant plan and totally lacking in technical feasibility. I think it could work. I mean, what's the worst that could happen? Just launch the thing and figure it out later.
Here it is.
Keep Dawn on the launch pad. Send it to Mars.
Put Phoenix on the launch pad as scheduled. Send it to Ceres.
Everyone's a winner! Especially Dana, who wouldn't have to stay in Florida until Dawn's September launch and can come to the party at his own apartment tomorrow night.
