JRTI delivered B1052 at 5pm ET today and would need to be back at the LZ, 630km downrange, on Sunday night for Starlink 4-34 if the current NET date is to hold.

At 6.5 knots (fast) the droneship would take 96 hours to reach the LZ. The launch NET is less than 96 hours away. 1/2

So, my analysis of the situation has two options:

1. SL 4-34 is going to be delayed from Sunday night
2. SpaceX is going to expend the first booster they fly 14 times

Option 2 is total rampant speculation. An FCC permit DOES exist to use the droneship for this mission. (2/2)

CORRECTION: At 6.5 knots (fast), it would take Just Read the Instructions droneship 50 hours to sail 630 km downrange to the typical Starlink LZ.

SL 4-34 on Sunday remains possible if they get the droneship turned around ASAP.

Correction to earlier tweet issued 7 hours ago.

JRTI departed at 2:30 EDT..

Departure! Just Read the Instructions drone ship got underway from Port Canaveral at 2:30am for Starlink 4-34.

That's just 9 hours after delivering B1052 from the previous mission.

Despite the rain, Just Read the Instructions delivered B1052 to port last night. Instructions? Offload and depart for the next mission. Depart the did at 2:30 am. Fair winds tug crew!

Looks lik the booster used is actually B1067.6, not B1051.14 as previously listed on Next Spaceflight.

They've gotten lots of booster assignments wrong recently, for some reason.

SpaceX is likely playing musical chairs with booster assignments, switching pads and missions often probably causes boosters to shuffle often. No way Nextspaceflight can know for absolute certainty.

What was the reason for this evenings booster static fire of a Starlink mission? Thank you.

Starlink 4-34 (Sun): JRTI droneship is hauling downrange, under the tow of tug Kurt J Crosby.

With a crazy turnaround time from the last mission, JRTI should reach the LZ around midday on Sunday, 11 hours before T-0. 💪😱

Impressive stuff.

Not clear if the static fire actually happened or not. Very heavy rain prior to T-0 may have been an issue (and complete lack of visibility meant the pad couldn’t be observed).

Can only speculate why SpaceX wanted a static fire. Perhaps one, or more, engines have been replaced?

Guilty. These last few ones have been in part my fault (won't go into the embarrassing details of that lol) and in other part SpaceX switching pads and boosters late into the campaign which frankly caught me off guard

Obvious explanation would be that either the static fire could not be done and had to be postponed, or it found an issue and they'll have to do some stuff at the aft end and possibly static fire again.

Until other information comes out, I assume they had to scrub that static fire which went all stealth due to weather and then punt it to after the launch from the other pad. So probably another static fire attempt coming up, with the date moved to accommodiate that.
