Next launch attempt: Saturday, May 30th, 3:22pm EDT.
Webcast will remain on until Bob and Doug are out of the rocket (about 40 minutes to unload).  Crew must wait until the fuel is offloaded and rocket is unarmed, then Crew Access Arm will swing back and crew can disembark.

Crew seeing raindrops on the windows. Understand the need to scrub. "We got the easy job."

Scrubbed due to 3 rule violations - all 3 expected to clear 10 minutes after today's T-0.  The 3 rules were Natural Lightning, Field Mill, and Anvil Clouds.

Crew says the ship was great, appreciated the team's hard work to get here, ready to go on Saturday.
Fuel offload update: stage 1 is a little over 20% onboard, stage 2 is 26% onboard.  Nominal offload rates.
