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.

Elon Musk’s xAI brings 1GW Colossus 2 AI training cluster online
Elon Musk shared his update in a recent post on social media platform X.
xAI has brought its Colossus 2 supercomputer online, making it the first gigawatt-scale AI training cluster in the world, and it’s about to get even bigger in a few months.
Elon Musk shared his update in a recent post on social media platform X.
Colossus 2 goes live
The Colossus 2 supercomputer, together with its predecessor, Colossus 1, are used by xAI to primarily train and refine the company’s Grok large language model. In a post on X, Musk stated that Colossus 2 is already operational, making it the first gigawatt training cluster in the world.
But what’s even more remarkable is that it would be upgraded to 1.5 GW of power in April. Even in its current iteration, however, the Colossus 2 supercomputer already exceeds the peak demand of San Francisco.
Commentary from users of the social media platform highlighted the speed of execution behind the project. Colossus 1 went from site preparation to full operation in 122 days, while Colossus 2 went live by crossing the 1-GW barrier and is targeting a total capacity of roughly 2 GW. This far exceeds the speed of xAI’s primary rivals.
Funding fuels rapid expansion
xAI’s Colossus 2 launch follows xAI’s recently closed, upsized $20 billion Series E funding round, which exceeded its initial $15 billion target. The company said the capital will be used to accelerate infrastructure scaling and AI product development.
The round attracted a broad group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group. Strategic partners NVIDIA and Cisco also continued their support, helping xAI build what it describes as the world’s largest GPU clusters.
xAI said the funding will accelerate its infrastructure buildout, enable rapid deployment of AI products to billions of users, and support research tied to its mission of understanding the universe. The company noted that its Colossus 1 and 2 systems now represent more than one million H100 GPU equivalents, alongside recent releases including the Grok 4 series, Grok Voice, and Grok Imagine. Training is also already underway for its next flagship model, Grok 5.

Tesla AI5 chip nears completion, Elon Musk teases 9-month development cadence
The Tesla CEO shared his recent insights in a post on social media platform X.
Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk.
The Tesla CEO shared his recent insights in a post on social media platform X.
Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.
This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.
