Starship/Superheavy at T-4:00 minutes on July 16th.

FINAL UPDATE: See this post for a report on the flight.

UPDATE: Delayed 24 hours due to weather. Now scheduled for 5:45 pm (Central) on July 24th. More specifically, the weather above the Gulf was too cloudy for good observations of Starship’s heat shield during ascent. The company decided to delay until tomorrow, when conditions is expected to be “ideal.”

Now that SpaceX has confirmed the launch date for the 13th orbital test flight of Starship/Superheavy for July 20, 2026 July 23, 2026 July 24, 2026, with a 90-minute launch window beginning at 5:45 pm (Central), it is time to provide my readers with the many ways they can watch the launch. I have embedded several live streams below. SpaceX’s live steam can be found here. I have embed it below:

Watch Starship's thirteenth flight test https://t.co/qkYYJiX24h

— SpaceX (@SpaceX) July 23, 2026

The flight plan remains the same as last week, a low orbit that will bring the ship down in the Indian Ocean. The main goals are to test the Raptor-3 engines, bring Superheavy back as planned, relight a Raptor-3 engine in orbit, and test the ship’ thermal tile system during re-entry. In addition, the company will attempt to deploy 20 actual Starlink satellites rather than dummies.

UPDATE: Less than a few hours after I posted this announcement, SpaceX changed the launch date from July 20th to July 23rd. The post below now reflects that change.

SpaceX today issued an update confirming the company’s intention to launch Starship/Superheavy on its 13th test orbital launch July 23, 2026, one week after the rocket had a launch abort at T-0 seconds.

The 90-minute launch window opens at 5:45 pm (Central).

The update describes the mission, which remains unchanged from last week, but provides no details as to what the company has done to correct the issue that caused four Raptor-3 engines in Superheavy to misfire. Previously Musk had indicated they would replace two engines, but no further information has as yet been released.

Regardless, it is clear the company is pushing hard to complete this launch, as it wishes to go to full orbital test flights on the next mission.

Starship/Superheavy today, just after engine abort

While all looked perfect right up until engine ignition at T-0 second in today’s attempt to fly the 13th test orbital flight of SpaceX’s Starship/Superheavy, the rocket then shut down, aborting the launch.

At T-0 the engines did ignite for a second, after the water deluge system had activated as planned. The company almost immediately announced they were scrubbing for the day. As many have noted below in the comments, once that deluge system runs, they can’t launch again that day. It takes too long to refill the tanks.

Subsequently we have learned that 4 Raptor engines in the inner ring of Superheavy did not light. Musk has since said that at least two will be replaced. I suspect after they inspect the engines they might replace all four. They will likely then do another full static fire test before attempting a launch. Expect a delay of about a week.

Starship/Superheavy on the launchpad prior to 12th test flight in May

The Federal Aviation Administration (FAA) today closed out its investigation of the 12th orbital test flight of Starship/Superheavy and cleared SpaceX to go ahead with the 13th test flight.

In truth what the FAA did was rubberstamp SpaceX’s own investigation into that flight, almost immediately after the company announced on July 11, 2026 that it was targeting July 16, 2026 for launch. The company has now posted a complete description of that investigation and the flight plan for the 13th flight.

First the cause of the failure of Superheavy to successfully return as planned:

At stage separation on Flight 12, slight differences in engine startup on the ship [Starship] caused the directional flip of the booster to be off by approximately 90 degrees. The startup sequence has been modified to be more robust to timing variability and more reliably flip in the desired direction, which is done to increase overall performance.

After stage separation and the flip, the Super Heavy booster attempted its boostback burn. Five of its 33 engines experienced issues when attempting to re-light causing the boostback burn to end early. The Super Heavy on this upcoming flight has hardware modifications to improve re-light reliability along with updates to engine alarms and aborts to match the conditions seen in the multi-engine flight environment.

In addition, hardware changes were made to the engines on Starship, addressing the failure of several to light during flight 12.

The 13th test flight will once again follow the low orbital path used in the past few flights that will bring it down in the Indian Ocean. A relight of a Raptor-3 engine in orbit will once again be on the schedule. Starship will also deploy for the first time 20 actual Starlink satellites, rather than dummy prototypes. Six will be outfitted with cameras to observe Starship’s heat shield as it and the satellites de-orbit.

Finally, the ship will do more tests of its heat shield and tiles during re-entry.

If all goes well, this will lay the groundwork for the first full orbital flight on the next launch, likely to occur about a month or so later.

Link here. The article has a nice video of the longest static full engine static fire test — 24 seconds — of Superheavy prototype #20, as it is being prepared for the thirteenth orbital test flight.

The key quote in the article however is this:

Ship 40 is still in Mega Bay 2, getting some final touches before getting its payload and rolling out to the launch site. Assuming Ship 40 does not need any further engine testing, it just needs to get its payload and roll out to the launch site. Once there, it will get stacked on Booster 20, where SpaceX will likely perform either a tanking test or a full Wet Dress Rehearsal due to changes to the tank farm.

Once all preflight testing and checkouts are complete, the stack will be ready for launch, which, based on notices from the Federal Aviation Administration, marine safety notices, navigational hazard warnings, and airspace closures, is currently targeted between July 15 and July 21.

The article adds that FAA approvals are still needed, though based on its behavior since Trump took office this should cause no delays.

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.
