SpaceX Crew Dragon switches ports to make room for Boeing’s Starliner do-over
Update: For the second time, a SpaceX Crew Dragon spacecraft has successfully swapped International Space Station (ISS) docking ports in orbit – this time to make way for Boeing’s planned Starliner Orbital Test Flight do-over.
If Starliner’s second orbital flight test is more successful than the first, which failed almost immediately after launch, the Boeing spacecraft will launch no earlier than July 30th, rendezvous and dock with the ISS, and spend approximately five days at the station before attempting to return to Earth. Once Starliner departs, freeing up the forward docking port, SpaceX and NASA will likely have to perform a second Crew-2 port relocation, moving Dragon back to its original port to set the stage for the CRS-23 Cargo Dragon resupply mission scheduled in late August.
SpaceX and NASA are on track for the Crew-2 Dragon spacecraft currently docked to the International Space Station (ISS) to perform a “port relocation” maneuver early Wednesday, effectively opening the door for Boeing’s Starliner flight test do-over.
Scheduled to launch on a United Launch Alliance (ULA) Atlas V rocket no earlier than (NET) July 30th, Boeing’s Starliner will be flying for the first time since the spacecraft’s near-catastrophic Orbital Flight Test (OFT) debut in December 2019. During Starliner’s inaugural test flight, a combination of inept Boeing software development, shoddy quality control, and inexplicably lax NASA oversight allowed the spacecraft to launch with inoperable software.
As a result, things went wrong mere seconds after Atlas V – which performed nominally – deployed Starliner. Almost as simple as using the wrong clock, the first software fault – something that would have been instantly caught with even the most rudimentary integrated systems test – caused Starliner to think it was in a different part of the OFT mission and waste much of its fuel with thousands of unnecessary thruster firings.
Aside from pushing Starliner’s maneuvering thrusters beyond their design limits, those unplanned and unexpected misfirings also threw the spacecraft off course, obfuscating Boeing and NASA’s ability to communicate and command the spacecraft and troubleshoot the situation at hand. Eventually, the company regained control of Starliner, but not before it had burned through most of its propellant reserves – precluding plans for to rendezvous and dock with the ISS.
Less than three hours before reentry, Boeing also uncovered a separate thruster-related software issue that could have caused the Starliner capsule to lose stability and re-impact its expendable trunk section after separation.
Ultimately, with so many issues and a failure to gather any kind of data related to operations at and around the ISS, NASA thankfully forced Boeing to plan to repeat OFT with Orbital Flight Test 2 (OFT-2). Scheduled to launch in December 2020 as of the second half of that year, OFT-2 ultimately slipped – both for scheduling and technical reasons – to March, June, and finally July 30th, 2021.

More than 19 months after Starliner’s ill-fated debut, NASA and Boeing are now almost ready for the spacecraft’s critical do-over. For unknown reasons, though, NASA and/or Boeing apparently need (or prefer) Starliner to use a specific docking port – the same port SpaceX’s second operational Crew Dragon spacecraft is currently docked to. According to NASA and Boeing, Starliner needs to use that forward docking port because it has not been qualified for zenith docking, which is a bit more complex. As a result, SpaceX and NASA have scheduled a port relocation maneuver around 7am EDT (UTC-4) on Wednesday, July 21st.
SpaceX’s first relocation occurred in early April to prepare for the arrival of a second Crew Dragon later that month. When Crew-1 Dragon departed a few weeks after the maneuver, it would leave the station’s zenith (space-facing) port free for a Cargo Dragon 2 spacecraft scheduled to arrive around one month later. Due to the station’s geometry and port layout, only the zenith port allows its robotic Canadarm2 arm to unload unpressurized cargo from Dragon’s trunk.
Already at the forward port, the Crew-2 Dragon will thus be moving to the zenith port for Starliner’s brief 1-2 week stay at the ISS. However, as may have become clear, Crew Dragon will then have to re-relocate to the forward port for any future Cargo Dragon missions – one of which happens to be scheduled to launch with an important unpressurized payload as early as August 29th.
Regardless of why, it’s hard to ever complain about seeing Dragons fly. Tune in around 6:30 am EDT (10:30 UTC) to watch Crew Dragon C206 maneuver around an orbital space station.

SpaceX wants to catch Starship for launch 14, Elon Musk says
Just hours after Starship Flight 13 achieved a successful soft splashdown of its upper stage in the Indian Ocean on July 24, Elon Musk announced an ambitious next step for the company’s next launch of the rocket.
“Unless we discover problems after mission data review, SpaceX will attempt to catch the ship with the tower on [the] next flight,” the SpaceX CEO posted on X on Friday.
That “next flight” is expected to be Flight 14. The plan involves returning the Starship upper stage, commonly called the “ship,” to the Starbase launch tower in Texas and catching it mid-air using the same mechanical “chopsticks” arms that have already proven themselves with the Super Heavy booster.

A successful catch would mark the first time an orbital-class upper stage has been recovered this way, advancing SpaceX’s goal of full and rapid reusability for the entire vehicle.
SpaceX has already demonstrated the tower-catch technique multiple times with Super Heavy. The first successful catch came on Flight 5 in October 2024, when Booster 12 was plucked from the sky by the Mechazilla arms. Subsequent flights, including those involving Boosters 14 and 15, repeated the feat. Several of those recovered boosters were later inspected, refurbished, and flown again, proving the system’s viability for quick turnaround.
Traditional reusable rockets, such as SpaceX’s own Falcon 9 or Blue Origin’s New Shepard, land on legs either on land or droneships. Rocket Lab has recovered its small Electron first stages by helicopter, but those are far lighter vehicles.
SpaceX Starship just nailed something it’s never done before
The China Academy of Launch Vehicle Technology (CALT), a subsidiary of the China Aerospace Science and Technology Corp. (CASC), completed a catch of its booster on July 10. They are the only entity besides SpaceX to attempt and complete the feat.
Flight 13 provided encouraging data. The ship executed a controlled reentry, flipped, and soft-landed intact in the ocean after deploying Starlink satellites, offering the first clear post-splashdown views of an undamaged heat shield. The Super Heavy booster, meanwhile, experienced a harder splashdown in the Gulf of Mexico.
Musk has previously stressed that ship catches would only follow multiple successful soft ocean landings to minimize risk of debris over land.
If Flight 14 succeeds, SpaceX would take a major stride toward routine, rapid reuse of both stages—critical for lowering launch costs and supporting ambitious plans for lunar and Mars missions. For now, teams are reviewing the Flight 13 data. Should everything check out, the next Starship flight could deliver one of the most spectacular recoveries in aerospace history.

Tesla to open source Model S and Model X designs and software
In a move echoing its earlier commitment to open innovation, Tesla CEO Elon Musk announced recently that the company plans to make the design and software of its Model S and Model X fully open source.
This follows the same approach Tesla took with its original Roadster, releasing all available design, engineering, and diagnostic materials in November 2023 so that “whatever we have, you now have.”
Just as Tesla made the original Roadster design & software open source, we plan to do the same with Model S & X
— Elon Musk (@elonmusk) July 24, 2026
The Model S, introduced in 2012, was Tesla’s first mass-produced vehicle and a groundbreaking luxury electric sedan. It offered impressive range, rapid acceleration, and over-the-air software updates that redefined expectations for electric cars.
The Model X, launched in 2015, built on that foundation as a high-performance electric SUV notable for its distinctive falcon-wing doors, spacious interior, and advanced safety features. Both models served as flagships that helped establish Tesla as a leader in the EV industry and popularized long-range battery-electric vehicles.
Production of the Model S and Model X was wound down earlier in 2026, with manufacturing ending in the second quarter. Tesla redirected the Fremont factory space previously used for these vehicles toward higher-priority projects, including Optimus humanoid robots and the Cybercab autonomous vehicle.
By the time of Musk’s open-source announcement, custom orders had closed and only remaining inventory was available.
Open-sourcing the designs and software offers several clear advantages. Owners of these aging but still capable vehicles gain better access to technical documentation, diagnostic tools, and software resources, making independent repairs and modifications easier and more affordable.
Independent repair shops and third-party specialists can support the large existing fleet without relying solely on Tesla’s service network. Enthusiasts and engineers can study real-world implementations of Tesla’s battery, powertrain, and software systems, potentially accelerating broader industry progress in electric mobility.
The step aligns with Tesla’s 2014 patent pledge and its overall mission to advance sustainable transport by sharing hard-won knowledge rather than locking it behind proprietary walls.
By releasing these materials now that the models have left production, Tesla ensures continued support for its early adopters while freeing internal resources for future technologies. The open-source release of the original Roadster already enabled simulations, community projects, and deeper technical understanding.
Extending that practice to the Model S and Model X should deliver similar benefits on a larger scale, helping keep these influential vehicles relevant and repairable for years to come

Tesla flexes incredible Robotaxi metric that skeptics will hate
Tesla flexed one incredible Robotaxi metric during the Q2 Earnings Call that skeptics have to hate to hear. The company’s platform has already driven more than 380,000 miles of unsupervised ride-hailing across several states with no notable incidents.
During the company’s Q2 Earnings Call on Wednesday, Vice President of AI, Ashok Elluswamy, said:
“First of all, I’d like to state that the Robotaxi program has been operating extremely well. Especially in terms of safety, the program has had an impeccable safety record. We have driven more than 380,000 miles of unsupervised Robotaxi, now across six cities in two different states. We have had zero notable incidents. Any reports have been of other actors impacting us when we were stationary. I like to emphasize how safe the operation has been so far. Zero notable incidents over 380,000 miles.”
Elluswamy’s claim over Robotaxi miles is a significant milestone for Tesla in the grand scheme, especially considering this is a sizeable number of miles without any incident.

Tesla’s self-driving approach is much different than that of other companies. Tesla has maintained that vision is the only thing needed to have a solid and effective self-driving suite. Many self-driving companies utilize things like LiDAR, sensors, and other elements to improve performance, but Elluswamy sent a jab at those who believe it’s needed.
“Historically, the so-called experts have always claimed that you need LiDARs, radars, HD maps, and the entire kitchen sink to drive safely. Here we show that such is not true. You can have safe, comfortable, and affordable autonomy with just cameras. This record should be a huge validation of Tesla’s entire AI approach.”
The feat of accumulating this many miles without any driver behind the wheel is impressive. The thing is, Tesla is also doing this across several different locations, with varying traffic rules, pedestrian levels, weather patterns, and other important factors.
While Tesla is not ready to roll out an unsupervised platform completely, it is a slow but steady indication that the company is well on its way to figuring things out.
The company’s attitude toward expansion is slow, safe, and controlled, and despite this huge milestone, it will still be some time until we see Tesla truly unleash unsupervised rides more aggressively.
