T-minus 35 minutes and counting. "Launch auto has started."

The beginning of the launch autosequence kicks off the first steps to begin pumping propellants into the 213-foot-tall Falcon 9 at pad 40 at Cape Canaveral Air Force Station.

RP-1 kerosene and liquid oxygen are now being pumped into the Falcon 9 rocket. The liquid oxygen is chilled to near minus 340 degrees Fahrenheit (minus 206 degrees Celsius).

I'm on the roof of NASA's Vehicle Assembly Building awaiting today's launch of Falcon 9 and CRS-18 from Space Launch Complex 40 at 6:24pm EDT. As always, the view is incredible!

Weather is currently observed "no go" for the surface electric field rule. This rule screens for the potential of an electrical discharge, or lightning, during launch.

T-25mins. Fueling continues to proceed nominally. No technical issues.

Weather is NO GO. Two rules including surface electric fields. Still progressing at this time.

SpaceX will continue counting to T-30secs and decide then... just in case.⁠

This is not an official scrub yet, but we all know where this is basically headed. Hold tight, folks. Not done yet, but almost a 0% chance at this time.⁠

NASA reports SpaceX will take the countdown to T-minus 40 seconds before aborting the launch if weather conditions remain "no go" for liftoff.
