SpaceX aces fourth Starship flight test
SpaceX successfully launched and landed its Super Heavy booster and Starship on its fourth integrated flight test, with each making a soft splashdown in the water.
Starship took to the skies at 7:50 am CT from a foggy Starbase, Texas, in an effort to surpass previous flight milestones.

As the countdown hit zero, 32 of 33 Raptor engines on the Super Heavy booster lit, with the outlier being an engine on the outer ring. Despite the engine out, the booster still ascended with ease away from the launch mount and broke through the thick fog into clear blue skies with views streamed back to the ground from just above one of the grid fins.
As Starship climbed, everything continued to operate nominally all the way through the hot staging which saw Super Heavy Booster 11 shut down all but its 3 center Raptor engines as Starship 29 lit its 6 Raptor engines to pull away from the massive booster. As soon as Starship was clear, Booster 11 completed a flip and boostback burn to begin its trip for a planned soft touchdown in the Gulf of Mexico by relighting 10 Raptor engines.
Once the boostback burn was complete, the hot staging ring was ejected to reduce the overall mass of the booster to help it survive reentry and landing. Future Super Heavy boosters will feature a lighter hot staging ring that will not be ejected. As the booster made its way back, it re-orientated to vertical and began re-entry back through the atmosphere, and unlike the Falcon 9, it does not perform an entry burn.

At around 7 minutes and 15 seconds into flight, the Super Heavy booster lit 12 out of a planned 13 engines for its landing burn, followed shortly by quite a bit of debris flying by the onboard camera, but it did not affect anything critical as seconds later Booster 11 made a successful splashdown in the Gulf of Mexico before a slow planned tip over into the water.

As Booster 11 completed the first successful soft landing, Starship 29 fired its six Raptor engines, three sea level and three vacuum, with engine shutoff coming in at eight and a half minutes into flight. The starship then entered a long coast phase as it passed between the Florida Keys and Cuba and transited over the Atlantic Ocean, followed by Africa.
During IFT-3, live views were provided for a majority of this portion but due to an unknown issue, cameras didn’t come back until just before 37 minutes into the flight. Elon Musk posted on X that they had a data signal the entire time including live views from internal cameras.
45 minutes into the flight, the true test of Starship began as plasma started to build up, but this time, Starship was in the correct orientation, and the heatshield was facing the correct way to give the ship its best chance at survival.
As Starship descended, plasma build-up increased with callouts from mission control noting rising temperatures on the nose but all within acceptable limits. At just over 54 minutes into the flight, Starship made it further than the third flight test and into unknown territory.

57 minutes into the flight, peak heating had passed but tiles were starting to fall away from the forward flap followed by melting of the lower portion, despite this damage, Starship held strong and in the correct orientation as it descended.
Starship continued its descent and, with significant damage, still made it through to its own landing burn and performed its flip to a vertical orientation and a soft touchdown in the Indian Ocean west of Australia.

Even with the damage inflicted on Starship, it completed all test objectives while providing SpaceX with incredibly valuable data that will be used to make the ship stronger on future test flights. The Starlink antenna also survived the entire flight which ensured this data made it back to mission control.
With this successful mission complete, SpaceX could launch the 5th flight by mid to late July and possibly even attempt a catch of the Super Heavy booster according to Elon Musk.

SpaceX has updated its target for the thirteenth integrated flight test of Starship, aiming for as early as Thursday, July 23. The 90-minute launch window opens at 5:45 p.m. CT from the company’s Starbase facility in South Texas.
The target flight was initially rescheduled for today, but SpaceX pushed it back again.
This latest adjustment follows an aborted attempt earlier in the week and reflects the iterative, rapid-development approach that has defined the Starship program. With the vehicle already stacked and ground teams making final preparations, the mission represents another step toward proving the full reusability of the world’s most powerful rocket system.

The original launch attempt on July 16 was scrubbed at T-0 when several Raptor engines on the Super Heavy booster failed to ignite properly. The automatic abort system triggered just as the engines began their startup sequence, preventing liftoff.
SpaceX CEO Elon Musk confirmed that some engines did not start as expected, prompting the decision to replace two Raptors on Booster 20 to ensure reliability. The issue occurred despite a successful full-duration static fire earlier, highlighting the complexities of coordinating 33 engines under flight conditions.
This cautious approach underscores SpaceX’s commitment to safety amid an aggressive test cadence.
Flight 13 builds directly on the lessons from Flight 12 in May 2026. The Super Heavy booster’s primary goals include a successful liftoff, ascent, stage separation, boostback burn, and controlled splashdown in the Gulf of America.
Hardware and software modifications address the off-nominal flip and boostback burn problems from the prior flight, where propellant slosh and engine relight issues led to an uncontrolled impact.
For the Starship upper stage, objectives include deploying 20 operational Starlink V3 satellites, the first real payload of this type, performing a single Raptor engine relight in space, and executing a controlled entry, descent, and splashdown in the Indian Ocean. Propulsion upgrades aim to improve engine-out capability after one vacuum Raptor was lost on Flight 12.
Additional test elements focus on heat shield performance. Six satellites carry cameras to image the tiles during flight, while white-painted tiles and upgraded attachments on flaps and the aft skirt will gather data for future reusability.
The FAA completed its mishap investigation into Flight 12 earlier this month, clearing the regulatory path.
This suborbital mission, the second with V3 vehicles, advances Starship toward operational missions, including potential crewed flights and support for NASA’s Artemis program. Success would mark significant progress in rapid reusability and satellite deployment from the massive system.
Elon Musk dismissed reports claiming SpaceX had placed a massive order for NVIDIA GPUs worth $52 billion. The denial came hours after Taiwanese media, citing unnamed industry sources, reported that SpaceX planned to acquire approximately 13,000 AI server racks, equating to roughly 1 million GB300 GPUs, from Foxconn.
Each rack was estimated at around $4 million, with deliveries potentially starting in late 2025.
The story suggested this would mark SpaceX’s first major foray into Foxconn-manufactured NVIDIA hardware, breaking from suppliers like Supermicro and Dell. Musk responded bluntly on X:
This is fake news
— Elon Musk (@elonmusk) July 20, 2026
Despite the denial, the rumored scale aligns with SpaceX’s explosive growth in AI infrastructure. NVIDIA’s GB300 (successor to the GB200 NVL) racks deliver unprecedented performance for large-scale training and inference. A $52 billion commitment would dwarf most corporate AI budgets and provide the compute muscle needed for frontier models.
SpaceX already operates gigawatt-scale terrestrial clusters like Colossus in Memphis, Tennessee, and has monetized them aggressively through leasing deals.
SpaceX’s newest Starmind will make earth data centers obsolete
Major customers include Anthropic (paying ~$1.25 billion monthly for 220,000+ GPUs), Google (~$920 million monthly for 110,000 GPUs), and Reflection AI. These arrangements are projected to generate tens of billions in annual revenue, far outpacing traditional SpaceX businesses.
Such an investment would fuel internal AI efforts, particularly Grok models under the integrated SpaceXAI division, while supporting ambitious orbital data center plans. SpaceX envisions launching thousands of AI-optimized satellites powered by solar energy and cooled in space, bypassing terrestrial power and land constraints.
This “Starmind” constellation could position the company as a leader in space-based computing.
SpaceX as an Emerging AI Powerhouse
Once primarily known for reusable rockets and Starlink satellite internet, SpaceX has transformed into a multifaceted AI player.
The 2026 acquisition of xAI integrated Grok development directly into the company. Starlink’s low-latency global network complements massive compute clusters, enabling efficient data flow for training and serving AI models.
Musk has long argued that AI scaling demands solutions beyond Earth, citing things like real estate and electricity limits on the ground.
While the Foxconn deal may not be in the cards, SpaceX’s trajectory is continuing on the path of blending aerospace engineering with hyperscale AI to dominate both launches and intelligence infrastructure.
Elon Musk shed more details on the upcoming improvements to Tesla’s Full Self-Driving suite, specifically one that the CEO mentioned last week, which should help owners see fewer interventions.
Last week, Musk hinted that one major improvement that Tesla planned to roll out to Full Self-Driving users was the car’s ability “to remember your specific interventions and match each person’s individual preferences.”
Elon Musk says your Tesla will start to learn your individual preferences
This small bit of detail was linked to a post from Tesla community member Whole Mars, who said that FSD’s tendency to exit the carpool lane, a feature that owners can turn on but at times the car will disregard.
It sounds like, based on Musk’s two responses since that original post, it is safe to say the things FSD will start to remember are wide-ranging. However, it seems the biggest differences will be noticed with parking performance, which Musk continues to mention.
Highway Lane Preferences
The initial post Musk mentioned, with these new remembered preferences soon to arrive for Tesla owners everywhere, was the Carpool/Express Lane.
Tesla has a setting in the FSD menu that lets drivers enable HOV Lane travel. However, the car won’t always stay in that suggested or preferred lane.

— Elon Musk (@elonmusk) July 18, 2026
Some owners have also complained of left lane camping, an illegal maneuver in at least some states. Cruising in the passing lane has resulted in tickets for some, as it is illegal in over 30 states in the U.S.
Tesla did not confirm if these preferences would also be included in new FSD behaviors, but it would certainly help move the company toward fewer interventions.
Parking Preferences
This seems to be the real focus of the entire operation, as Musk stated several weeks ago that parking was overwhelmingly the most frequent reason for interventions.
The major issue with parking is not necessarily the parking “performance,” as FSD is generally good at parking. It definitely has its issues; we’ve recorded plenty of them, including this one as recent as last week:
Yeah it seems like FSD v14.3.5 is having some issues with parking early on https://t.co/Bw5ULfVmDq pic.twitter.com/RHdpjOEpIo
— TESLARATI (@Teslarati) July 13, 2026
However, the changes coming are more about preferences, meaning where you park and how your car enters the spot, either pulling in or backing in. Owners have also reported that pulling into the correct driveway is a relatively rare thing for FSD, something else that needs to be confronted.
Musk basically confirmed that all of these things would be part of Tesla’s plan to address driver preferences with FSD:
Yes
— Elon Musk (@elonmusk) July 20, 2026
It’s obvious there is something big coming with FSD, and the company’s focus seems to be eliminating any intervention that would be related to preferences. This is probably the biggest bottleneck between Tesla and being fully autonomous. Critical interventions do occur, but they are much less frequent.
The only time a driver should be taking over is because of a critical intervention; this seems to be the goal of Tesla right now.
This all seems to be a priority as Tesla continues to move closer to the prospect of unsupervised driving.
