Being in southern Cali I am so looking forward to this. My daughter is as well. We have seen a few launches go up, and then crash back into the ocean, but watching them attempt a landing, this is going to be special.

 

As always thanks for the updates/info DocM (and others too!) you guys really take some hard to grasp concepts and make them understandable even to my 16-year-old daughter who is just starting to grasp the basics of this, even after all these years of being super interested in space/rockets.

Not a problem, and if you have a question - ask. The only really dumb questions are those which go unasked.

This is going to be another nice "rapid-fire" launch series for SpaceX. Can't wait. :yes:

Weather is 60%, with the main concern being ground level winds.

Good landing of the S1, good orbit insertion for the S2. See ya at T-50 (ish) minutes. JRTI's lights are out.

Wind shear at 1,000 ft above droneship? F9B5 don't care about no damned wind shear ?

I believe, however, the droneship got a little annoyed with the landing ... the lights went out in Georgia ...

High seas too - a corner case test.

Also, a few minutes before F9 launched an Ariane 5 launched from Kourou, French Guiana. It too is in coast but no landing ;)
