Ok, great work with the coverage, everyone! I think due to the massive amount of interest we'll start a new thread for Thursday attempt.

I'll start that in the morning and leave this open for anything from Elon etc.

In the meantime, read up on the mission here:

Look at that wind shear @NASASpaceflight @ChrisG_NSF

Actually, what he highlighted is not the wind shear.  What he marked is the temp/dew point lines in the Skew T chart.  The winds and direction are on the right side.  The direction and speed between the 350 millibar and 250 millibar  heights is the issue this evening....massive change in direction and speed in a small vertical area.

Upper-level wind shear tomorrow looks like a major improvement from today:
