The giant specially designed barge that SpaceX plans to use to transport Starships and Superheavys from Boca Chica to Florida, dubbed “You’ll Thank Me Later”, arrived in Texas last week.

Avid Space, a Starbase streaming outlet part of Labpadre, captured the barge’s arrival, posting images, of which the one to the right is a screen capture. From the first link:

The retrofitted barge Marmac 31, nicknamed “You’ll Thank Me Later” by Elon Musk’s space firm, arrived at the Port of Brownsville last week. It will be used to carry Starship megarockets built at Starbase to Florida and eventually other destinations.

The Starbase-headquartered company has said it would use barges to float the rockets to Florida for launches from there until the Starship factory that it’s building at NASA’s Kennedy Space Center is complete. The company has been in talks with port officials about a 50-year lease for an 83-acre site that would be used as a terminal for the 400-foot-long rockets. Those negotiations are ongoing.

This barge’s arrival in Texas not only makes Starship launches from Florida more likely in the near future, it gives SpaceX the option to buy other launch sites along the Gulf coast, such as that rumored purchase in Louisiana.

UPDATE: One day after its announcement below, SpaceX announced another one day delay. The 12th Starship/Superheavy launch is now targeting May 21, 2026, with a launch window beginning at 5:30 pm (Central).

SpaceX earlier today announced a revised launch date for the 12th Starship/Superheavy orbital test flight, delayed one day from May 19, 2026 to May 20, 2026, with a launch window opening at 5:30 pm (Central).

No reason was given. I suspect weather might have played a factor, but it is also possible that some technical issues required a short delay.

Either way, the link to the X live feed will be posted here once it goes live. I will also embed it on Behind the Black once it goes live.

Starship/Superheavy (version 3) on launchpad

SpaceX yesterday announced that the 12th orbital test flight of its Starship/Superheavy rocket is now scheduled for May 19, 2026, with a launch window opening at 5:30 pm (Central).

The mission will be also be the first flight of what SpaceX calls Version 3 of both the booster and the spaceship, will include the first use of the Raptor-3 engine, and the first use of a completely redesigned launchpad.

The flight test’s primary goal will be to demonstrate each of these new pieces in the flight environment for the first time, with each element of the Starship architecture featuring significant redesigns to enable full and rapid reuse that incorporate learnings from years of development and test.

The booster’s primary test objective will be executing a successful launch, ascent, stage separation, boostback burn, and landing burn at an offshore landing point in the Gulf of America. As this is the first flight test of a significantly redesigned vehicle, the booster will not attempt a return to the launch site for catch.

The Starship upper stage will target multiple in-space and reentry objectives, including the deployment of 22 Starlink simulators, similar in size to next-generation Starlink satellites. The last two satellites deployed will scan Starship’s heat shield and transmit imagery down to operators to test methods of analyzing Starship’s heat shield readiness for return to launch site on future missions. Several tiles on Starship have been painted white to simulate missing tiles and serve as imaging targets in the test. The Starlink simulators will be on the same suborbital trajectory as Starship. A relight of a single Raptor engine while in space is also planned.

As an added potential test-to-failure, the company has also removed a single heat shield tile to test how Starship performs under this failure scenerio. The flight plan will be the same as the previous flights, designed to come down in the Indian Ocean.

A detailed description about the upgrades to Starship, Superheavy, and the ground systems can be found here.

The company will broadcast the launch live, which I will embed on Behind the Black once available.

Link here. The report includes a lot of very interesting information about how SpaceX is evolving its launch platforms and the tank farms that fuel the stages in order to make them operate more efficiently. For example:

In the past, on Pad 1, SpaceX had only four Liquid Oxygen (LOX) Pumps and six subcoolers, and three Liquid Methane (LCH4) Pumps with three subcoolers. This setup allowed SpaceX to start booster load at T-41:15 on Flight 11.

On Pad 2, SpaceX has five pumps and about 10 subcoolers worth of capacity on the LOX side, and four pumps alongside about six subcoolers worth of capacity on the LCH4 side. With these upgrades, along with larger supply lines, SpaceX can now load a full booster within 30 minutes, and each LOX ring takes only about 90 seconds to load. This now means SpaceX can load the Superheavy booster faster than a Falcon 9 and carry over 10 times the propellant. [emphasis mine]

Many of the tests have been more to prove out the fueling systems and launchpad than to test Superheavy.

Other tests however have been to prove out the new Raptor-3 engine. The company have increased the number of engines step by step so that the next test will be the first to test all 33 engines. I suspect that test will also be the full dress rehearsal countdown prior to launch.

Starship meanwhile is undergoing testing on the company’s nearby Massey test stand, the one that I think was rebuilt after an explosion last year.

Stay tuned. It appears the next and 12th orbital test flight will not be long in coming.

According to a tweet by Elon Musk today, the 12th orbital test flight of Starship/Superheavy is not going to happen in mid-April as previously hoped.

Instead, it is now pushed back to early to mid-May.

Next flight of Starship and first flight of V3 ship & booster is 4 to 6 weeks away.

In his tweet, “V3” refers to the third version of both Starship and Superheavy, incorporating many upgrades learned from the first eleven test flights. Version three will also be the first to use SpaceX’s Raptor-3 engine, the most powerful rocket engine ever built but with a much simplified design.

It is not clear what has caused this delay. The last test flight was in October 2025, which means there will be eight month gap between test launches, a much longer gap than desired by the company. Part of the delay was because the company was building a whole new launchpad for the rocket. Also, there were two tank failures during static fire tests of Superheavy that needed investigation and as well as pad repairs.

Still, time is marching on. SpaceX needs to launch this rocket, and begin doing it at a much faster pace. It can no longer complain about red tape, as under Trump that issue has been squashed quite effectively.

Link here. The testing has apparently verified the fueling system of Superheavy at the new launchpad.

Starship Flight 12 took another step toward launch, with Booster 19 completing an initial test campaign on the newly commissioned Pad 2 at Starbase, Texas. Culminating in a short Static Fire test, the series of tests was a first for Pad 2, the Block 3/V3 Super Heavy Booster, and for the upgraded Raptor 3 outside of single engine testing.

As the inaugural vehicle to undergo operations on this pad, B19’s campaign served as both a booster qualification test and a commissioning milestone for the expanded launch infrastructure, paving the way for a long-awaited static fire test of its Raptor 3 engines.

Lots of details worth reading. Ground testing will now shift to Starship. All in all, it does appear that an early April launch is likely.

Based on a tweet posted by Elon Musk on March 7, 2026, SpaceX now targeting early April for next and 12th Starship/Superheavy test orbital flight.

According to this update at nasaspaceflight.com, the Superheavy booster, the 19th prototype and the first version 3 booster, is now on the launchpad for final checks.

On March 8, Booster 19 left Mega Bay 1 and rolled down Highway 4 towards the launch site and Pad 2. This is the start of pad commissioning and booster engine testing for Block 3.

Booster 19 is mounted on Pad 2 to conduct multiple tests over the coming days. This will likely include ambient pressure testing, tanking tests with Liquid Oxygen (LOX) and Liquid Methane (LCH4), spin primes, and eventually a static fire, maybe even a couple of static fires. These tests are not only to help test the booster but also to test all of the pad systems.

While crews have run operations with the Pad 2 tank farm many times, they have never loaded an actual booster with propellant. With a booster finally on the pad, this will help in the final commissioning process.

For these initial pad and booster check-outs, #19 does not have all 33 engines installed. It appears the company wants to test the launchpad fueling system first, with the minimum number of engines needed.

Meanwhile, the Starship prototype that will fly, #39 in the series, is in the assembly building after completing its own series of tanking and launchpad tests.

I want to highlight two numbers — 19 and 39 — in order to illustrate how SpaceX does things versus NASA. Not only has SpaceX already completed eleven test flights of Starship/Superheavy, it has tested or flown 19 and 39 prototypes of each, in one manner or another. The company has a very rich history of hardware and testing as it ramps up towards operational flights. This practically guarantees that those operational flights will not only occur relatively soon, they will be relatively safe and robust.

This was all done in less than a decade, though most of the testing of those prototypes has occurred in the last six years.

NASA meanwhile began work on SLS about fifteen years ago, and has built two rockets total, and so far flown only one. Though the agency did a lot of tests of pieces of the rocket, it flew only one test launch, in 2022. SLS’s design is so cumbersome and expensive, the agency could not afford to fly it multiple times. Thus, much of its testing was done on computer screens, in simulations.

Which rocket would you want to fly on when both are operational?
