Instead, SpaceX pressurized the test tank, and the north arm was quickly closed and hit the tank. SpaceX is testing this as during actual catch operations, the arms will have to close and touch the booster in order to get the landing rails under the lift points.
While B14.1 has been prepared for tests with the “chopstick” arms, likely as part of testing the system’s response before any catch attempt, other activities at Starbase are preparing the site for a busy and active future of launches, at least when there are no storms in the area.
Now SpaceX also had temporary closures that are from 10:00 PM June 26 to 2:00 AM CDT June 27 (03:00 to 07:00 UTC June 27), with the same timings for June 27/28 and June 28/29. These were placed to transport the last of the tower sections from the Port of Brownsville to the Sanchez Site, however the barge carrying the tower are not due into port until June 28. It is very unlikely any of these closures will be used.

Weather conditions in the area became poor enough on June 20 that work had to be stopped at the facility. The winds would not allow safe work high up on the tower, while Highway 4 was flooded by heavy rains. The weather also forced a barge with launch tower elements to stop at Tampa during its voyage from Port Canaveral to Brownsville.
A second orbital launch pad is being built up at the site of the former suborbital launch pads, and a supporting foundation has been readied for the second tower. Large concrete pillars are now visible, and the last tower sections and “Mechazilla” parts are now back in transit from Florida through the Gulf of Mexico. The pillars appear different from the ones holding up the first orbital launch mount, and the new tower and launch mount designs will no doubt be informed by experience with the first orbital launch site at Starbase.

The orbital tank farm, which will support both launch pads, has received a new long horizontal tank this week to add capacity and is currently being installed. While the tank farm is being upgraded, older vertical tanks constructed much earlier in the program are now being dismantled.
By now all of the cryogenic shells that were on the old vertical tanks have been scrapped. The old tank farm, with tanks built in a similar manner to Starship test ships, will be gone to possibly make way for additional infrastructure related to the current or new launch pad.

Besides launch infrastructure, the program has had much work done on buildings like a new parking garage and office building. The parking garage is nearly complete, and a sign that it is operational will be if there is reduced traffic parking on the side of Highway 4. In the meantime, a new office building has received additional levels.
As for when Flight 5 will fly, the entire heat shield, made up of over 18,000 tiles, is being replaced so that will play a part in when the flight is ready. The old tiles are being replaced with newer and stronger tiles as well as an ablative heat shield underneath these tiles for further thermal protection.

Starship can now fly missions that have very similar profiles to Flight 4 with the existing FAA license, but a license modification is needed for any catch attempt. If Flight 5 does indeed proceed with a catch attempt at the tower for Booster 12, additional paperwork will need to be filed for this license modification.
Inspections and work are being done on the orbital launch pad and mount to prepare for Flight 5 as well. Elon Musk has indicated late July as the goal for flying this mission, but it is very likely this will slip to August or even early September. Regardless of when it flies, it will be another case of “excitement guaranteed” especially if a tower catch is attempted.
