Joe Hansen(@joehansen):Elon almost never flags a science launch like this. That is why I stopped on those four words. Falcon Heavy is standing on 39A with NASA’s Roman telescope. Rollout was this morning. Liftoff is 7:26 a.m. ET Sunday if weather holds. This is not a Starlink flight. Roman is a $4.3 billion observatory going to L2. Same neighborhood as Webb, but a field of view about 100 times Hubble. - Dark energy. - Dark matter. - A wide planet hunt. NASA is also nine months early. The rocket is the easy part now. The payload is the part that used to slip.
