SpaceX’s futuristic Crew Dragon astronaut walkway is ready for US human spaceflight revival
SpaceX has publicly revealed the sleek, minimalist design of the access arm that NASA astronauts will soon use to board Crew Dragon spacecraft, bringing to an end more than half a decade of U.S. dependency upon non-native rockets and space agencies to transport crew to the International Space Station.
After several months of concerted effort in a tent located on Pad 39A property, SpaceX engineers, welders, and technicians have nearly completed the most critical portion of the launch facility modifications and upgrades necessary to return the pad’s human spaceflight capabilities. Known as a Crew Access Arm (CAA), SpaceX will likely complete installation of the Arm by the end of August, wrapping up what is by far the most visible step yet towards returning astronauts to the ISS on American rockets and spacecraft.

SpaceX’s first flightworthy Crew Dragon spacecraft are currently in various late stages of production, assembly, and integration in pursuit of an uncrewed orbital debut no earlier than (NET) November 2018 and its first crewed demonstration flight as early as April 2019. The first Demonstration Mission (DM-1) Crew Dragon capsule is already at SpaceX’s Florida processing facility, while its trunk/service module and Falcon 9 Block 5 rocket could ship to Florida as early as late August or early September.
Boeing has already installed their own Starliner spacecraft Crew Access Arm at United Launch Alliance’s own LC-41 launch facility, although the design is definitely far more traditional than SpaceX’s comparatively wild departure from previous CAAs.
Prior to SpaceX’s lease of Kennedy Space Center’s Launch Complex 39A (LC-39A), the pad operated for the full length of NASA’s Space Shuttle program, supporting dozens of launches of the fundamentally flawed – albeit iconic and awe-inspiring – vehicle. Still, Pad 39A is most famous for the critical role it played in NASA’s Apollo Program, where it supported nearly all Saturn V launches and thus all but one (Apollo 10) of the nine crewed mission to the Moon, Apollo 8, and Apollo 11 through 17.
SpaceX and CEO Elon Musk are cognizant of this incredibly rich history, and it’s probable that humans will once again return to the Moon (at least its gravitational sphere of influence) from Pad 39A, but this time atop a SpaceX rocket and spaceship. A sister facility known as LC-39B, built to ensure two operational pads for the Space Shuttle, is also slowly tracking towards the debut of a different rocket targeting human exploration around the Moon, NASA’s Space Launch System (SLS).

SpaceX President Gwynne Shotwell recently reaffirmed that a 2017 contract (money in hand) to send two private individuals around the Moon is still alive and well, although Musk has also noted that that lunar tourism mission will likely be flown with BFR and BFS, pushing it into the early 2020s at the earliest. While several years out and taking a definite back seat to Crew Dragon’s safe and reliable debut and operation in low Earth orbit, it’s clear that a separate human spaceflight race is simmering in the background, pitting public efforts against private efforts in a bid to once again send humans to the Moon.

SpaceX Starship Flight 13 faces wrath of the Texas skies
SpaceX pushed Starship Flight 13 to Friday, blaming weather instead of the previous engine issues.
SpaceX called off Thursday’s launch attempt of Starship Flight 13, pushing the mission to Friday because of weather tied to Tropical Storm Bertha. The company confirmed the delay on X, noting “Now targeting Friday, July 24 for Starship’s thirteenth flight test, due to weather. A key objective for the flight test is to get clear imagery from the ground of Starship’s heatshield as it flies at a higher dynamic pressure during ascent, which won’t be possible with today’s weather conditions.”
This is the second delay for Flight 13 in two weeks. SpaceX first tried to launch the mission on July 16, but the countdown ended in an automated abort at T-0 when four of Super Heavy Booster 20’s 33 Raptor engines failed to ignite. Musk said at the time that two Raptors would need to be removed and replaced, as Teslarati reported. The company spent the following week destacking Ship 40 and Booster 20, swapping engines, and running leak checks before restacking the vehicle on Pad 2 Wednesday night, according to Spaceflight Now’s live coverage.
Unlike the engine problem, Thursday’s delay has nothing to do with the hardware. SpaceX wants clean footage of Starship’s heat shield captured from the ground as the vehicle flies through max dynamic pressure, something the storm’s cloud cover over South Texas would not allow. The company said visibility should improve for Friday’s attempt, with the same 90 minute window opening at 5:45 p.m. CT.
Flight 13 will be the second outing for the V3 versions of Starship and Super Heavy, following their debut on Flight 12 in May. The mission carries 20 production Starlink V3 satellites, the first time SpaceX has flown operational satellites rather than mass simulators on Starship. Six of those satellites are fitted with cameras to inspect the heat shield from a different angle during ascent, giving engineers a second data source beyond the ground imagery the weather is currently blocking.
Booster 20 will attempt a boostback burn and a splashdown landing burn in the Gulf of America, while Ship 40 follows a suborbital trajectory toward a landing in the Indian Ocean. The flight plan largely mirrors Flight 12, though the booster will run a more aggressive ascent burn after max Q this time, and the ship’s heat shield includes load sensing tiles meant to measure stress at the higher dynamic pressure SpaceX is targeting.
If Friday’s attempt succeeds, Flight 13 could be the last suborbital test in the program. SpaceX is already looking to push for an orbital flight on Flight 14.
Investor's Corner
Google’s massive stake in SpaceX will shock you
In a striking revelation that underscores the lucrative crossover between Big Tech and space exploration, Alphabet Inc., Google’s parent company, disclosed a massive $94.1 billion equity stake in SpaceX following the rocket company’s blockbuster initial public offering earlier this year.
The disclosure came in Alphabet’s quarterly filing, marking the first time the long-held private investment has been publicly valued at market prices. Google was an early backer, investing alongside Fidelity in 2015 with roughly $500-900 million at a time when SpaceX was valued around $12 billion.
That bet has delivered extraordinary returns, roughly a hundredfold, transforming a strategic play on satellite internet and launch capabilities into one of Alphabet’s largest assets.
Google, $GOOGL, has said they hold $94 billion in SpaceX, $SPCX, shares after IPO.

Of the total holding, approximately $80 billion remains subject to short-term post-IPO lockup restrictions, preventing near-term sales. An additional $14.1 billion faces longer-term restrictions, extending into the third quarter of 2027. This structure limits immediate liquidity but protects against market volatility as SpaceX transitions into public trading.
The SpaceX position contributed significantly to gains in Alphabet’s broader investment portfolio, which also includes a major stake in AI leader Anthropic. Combined, these holdings helped drive nearly $100 billion in investment gains during the second quarter, providing a substantial boost to net income amid ongoing AI spending pressures.
Analysts view the disclosure as validation of Alphabet’s venture strategy beyond its core search and cloud businesses. The investment aligns with deeper ties, including reported multi-billion-dollar deals for AI computing capacity on SpaceX infrastructure. As SpaceX advances Starship flights, Starlink expansion, and ambitious Mars goals under Elon Musk, Google’s stake positions it to benefit from the commercialization of space.
For Alphabet, the windfall highlights how patient, forward-looking bets in transformative sectors can yield outsized rewards. While lockups temper short-term impact, the holding cements SpaceX as a cornerstone of Alphabet’s diversified portfolio in an era where aerospace, AI, and connectivity increasingly intersect. Investors will watch closely as restrictions lift and SpaceX’s public performance unfolds.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn
— Elon Musk (@elonmusk) July 21, 2026
The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.
