"Miss Chief is in route to scoop it out of the ocean."

So they're still not making catch attempts on both at once?
One fairing missed. That's what I gathered.

Perhaps, but weather conditions can be highly localized.  Ms Tree might have had good conditions while Ms Chief, five or ten miles away, could have been close enough to a squall to call off the catch attempt.

Has anyone subscribed to offshore AIS reported how close the sisters are during dual catch attempts?

Oh it’s a Ms Tree why they didn’t catch the other fairing half!  Maybe a ship rename is in order again?  8)

No, the ship couldn't be "in route" to the fairing if it missed a catch and it fell next to ship. Alternative explanation is they totally bungled the wording during the broadcast.

Er no. It splashed in the ocean, probably not far from the second ship - so now it's on-route (probably talking about hundreds of meters and not miles) to the splash location and will fish it out.

Ms. Tree and Ms. Chief were both deployed on this recovery mission; each boat was to capture one of the two fairing halves.

Ms. Tree made a successful net capture of one fairing half.

Ms. Chief did not make a successful net capture, and is retrieving or already has retrieved the other fairing half, floating on the ocean.

Have I got this right?

It could very well be miles. Something outside an accepted range could cause the fairing or ship or both to waive off the catch attempt.

Correct.  And that is all we know.

What we don't know is if Ms. Chief missed her catch, or if they decided to waive off and not attempt a catch with that ship.

Does anyone know if they try to put extra distance between the ship and fairing if they determine a catch is unlikely?

I don't know what you're talking about, but how long do you think it would it take one of these very fast boats to cover a couple hundred meters? According to what they said during the broadcast, it was still heading to the fairing at the time they showed the caught fairing.

Wow. Check out the vapor cone on Falcon 9. We caught a little telescope slow-mo as it went supersonic.
Congrats @SpaceX on your record 6th re-flight!

Congrats to the SpaceX team and B1049 for flight and landing #6.  Starting to put up real numbers now.  On to #7!

This is where Starlink and reuse reinforce each other.  For what they're saving on boosters, they can easily afford to lose a payload at the rate they're cranking out Starlinks.  A commercial customer probably isn't willing to sign up for Flight 7 (yet), but Starlink is.

Excellent flight.  I hope SpaceX is never ok with losing a payload.

Regarding commercial customers, it seemed to me this morning that if Starlink is flying on flights 6 and 7, then those commercial folks are more likely to be comfortable with flights 3,4,5.

Also, it occurred to me that SpaceX should not need to discount launches for higher flight rate booster.

Falcon 9 must have been secured because Of Course I Still Love You droneship is on the move!

Recovery teams got underway at around 4:30pm EDT.

CelesTrak now has SupTLEs for 36 of 58 #Starlink satellites launched 1431 UTC today (Aug 18), generated from ephemerides provided courtesy of @spacex. We expect the remainder to be out within the next couple of hours. STARLINK-1611 currently leads the pack for pass calculations.

Starlink V1.0 L10 has reverted to the launch profile used by Starlinks L4 - L8, inserting into its coast phase at an altitude of 215km. There were a few glitches in the S2 data though, especially around the time of the landing burn, and I very much doubt that the 6g peak in the S2 acceleration plot is real. Still, it appears the L10 S2 throttled back about 50 seconds later than L7, and shutdown 7 seconds earlier, for exactly the same insertion velocity of 7,541m/s.
