SpaceX, NASA test escape zipline ahead of Crew Dragon’s astronaut launch debut
As part of continued preparations ahead of SpaceX’s Demonstration-2 mission (DM-2) that will debut Crew Dragon’s ability to support astronaut flight, SpaceX and NASA have successfully tested crew emergency egress (escape) systems at SpaceX’s primary crew launch facilities located at Launch Complex 39-A (LC-39A) at Kennedy Space Center in Florida. The successful verification tests have proven that SpaceX is ready to support crewed launches and preserve human life with effective escape methods, including a zipline mounted basket system that will whisk astronauts away from Crew Dragon and Falcon 9 in the event of a launch pad anomaly.
The formal launch pad escape verification test comes just a month after SpaceX and NASA CCP teams practiced astronaut recovery rehearsals – including emergency astronaut evacuation – from a high-fidelity Crew Dragon mockup capsule aboard the recovery Vessel GO Searcher.
Multiple teams from NASA and SpaceX including personnel from the Astronaut Office at NASA’s Johnson Space Center in Houston, NASA Flight Surgeons, SpaceX systems engineers, Kennedy Aero Medical, and Commercial Crew Program Safety worked together to successfully complete two full-dress rehearsals of different escape methods.
In a Commercial Crew Program (CCP) blog post, NASA CCP launch operations integrator Steve Payne stated that “this demonstration allowed all the various teams responsible for ground operations, system design, ground safety and emergency management to observe and verify the system is ready for operational use.”
The launch pad escape methods practiced at LC-39A simulated evacuation plans that would usher flight and pad crew members to safety should any sort of life-threatening anomaly occur during launch proceedings. Two different versions of escape methods were practiced – a quick emergency evacuation utilizing the zipline system and a less life-threatening situation using an elevator.
Both escape plans require that crew members are able to evacuate the crew access arm and crew-loading level of the Fixed Service Structure (FSS) at LC-39A, located some 265ft in the air. During SpaceX renovations of LC-39A the crew loading platform was moved roughly half a level higher to accommodate the Crew Dragon capsule’s position atop a Falcon 9 booster, as the Crew Dragon stack is far different from and significantly taller than the Space Shuttles that previously flew from LC 39-A.
One exit method demonstrated how both flight and pad crew members could exit the launch pad under non-emergency circumstances. NASA astronauts Bob Behnken and Shannon Walker participated in the exercises and began the first rehearsal at the end of the crew access arm (CAA) – known as a white room – and took an elevator in the FSS to the ground before being escorted to a safe location nearby.
The second rehearsal simulated an emergency (i.e. time-sensitive) egress with active escape alarms and fire suppression systems that required the astronauts and pad crew to escape the launch tower using slide-wire mounted – essentially a serious zipline – basket transport system. This method has been around for decades and during the SpaceX LC-39A renovations some much-needed upgrades were implemented, including a new braking system to control basket descent speed and modifications to allow easier exit from the baskets.
In the blog post, Behnken expressed excitement about the completion of the verification tests, as they bring him and his colleagues one step closer to launching to orbit aboard SpaceX’s Crew Dragon spacecraft. “It’s exciting to have this verification test behind us on our way to the SpaceX Demo-2 mission. Each time today when we headed down the crew access arm, I couldn’t help but think about what it will be like to strap into Dragon on launch day.”
Behnken’s words reflect the anticipation and excitement that is shared by all as we await the historic and triumphant return of human spaceflight from US soil when SpaceX’s Crew Dragon capsule carries astronauts to the International Space Station for the first time. SpaceX CEO, Elon Musk, recently stated that the Crew Dragon capsule (C204) and trunk that will support DM-2 and (hopefully) push SpaceX into a new era of human spaceflight is set to arrive in Florida as early as November 2019. The Falcon 9 booster (B1058) has already completed static fire testing in Texas and is likely already in Florida or set to arrive imminently.
If all goes as planned during Crew Dragon’s upcoming in-flight abort (IFA) test and NASA is able to efficiently complete its myriad of reviews and paperwork, SpaceX should be ready to launch its first astronauts into orbit early next year.

The deal, which was confirmed by Musk on X, highlights xAI’s effort to aggressively scale its operations.
xAI’s turbine deal details
News of xAI’s new turbines was shared on social media platform X, with user @SemiAnalysis_ stating that the turbines were produced by South Korea’s Doosan Enerbility. As noted in an Asian Business Daily report, Doosan Enerbility announced last October that it signed a contract to supply two 380 MW gas turbines for a major U.S. tech company. Doosan later noted in December that it secured an order for three more 380 MW gas turbines.
As per the X user, the gas turbines would power an additional 600,000+ GB200 NVL72 equivalent size cluster. This should make xAI’s facilities among the largest in the world. In a reply, Elon Musk confirmed that xAI did purchase the turbines. “True,” Musk wrote in a post on X.
xAI’s ambitions
Recent reports have indicated that xAI closed an upsized $20 billion Series E funding round, exceeding the initial $15 billion target to fuel rapid infrastructure scaling and AI product development. The funding, as per the AI startup, “will accelerate our world-leading infrastructure buildout, enable the rapid development and deployment of transformative AI products.”
The company also teased the rollout of its upcoming frontier AI model. “Looking ahead, Grok 5 is currently in training, and we are focused on launching innovative new consumer and enterprise products that harness the power of Grok, Colossus, and 𝕏 to transform how we live, work, and play,” xAI wrote in a post on its website.

Tesla (NASDAQ: TSLA) stock received a price target update from Pierre Ferragu of Wall Street firm New Street Research, citing the company’s growing lead in self-driving and autonomy.
On Tuesday, Ferragu bumped his price target from $520 to $600, stating that the consensus from the Consumer Electronics Show in Las Vegas was that Tesla’s lead in autonomy has been sustained, is growing, and sits at a multiple-year lead over its competitors.
CES 2026 validates Tesla’s FSD strategy, but there’s a big lag for rivals: analyst
“The signal from Vegas is loud and clear,” the analyst writes. “The industry isn’t catching up to Tesla; it is actively validating Tesla’s strategy…just with a 12-year lag.”
The note shows that the company’s prowess in vehicle autonomy is being solidified by lagging competitors that claim to have the best method. The only problem is that Tesla’s Vision-based approach, which it adopted back in 2022 with the Model 3 and Model Y initially, has been proven to be more effective than competitors’ approach, which utilizes other technology, such as LiDAR and sensors.
Currently, Tesla shares are sitting at around $433, as the company’s stock price closed at $432.96 on Tuesday afternoon.
Ferragu’s consensus on Tesla shares echoes that of other Wall Street analysts who are bullish on the company’s stock and position within the AI, autonomy, and robotics sector.
Dan Ives of Wedbush wrote in a note in mid-December that he anticipates Tesla having a massive 2026, and could reach a $3 trillion valuation this year, especially with the “AI chapter” taking hold of the narrative at the company.
Ives also said that the big step in the right direction for Tesla will be initiating production of the Cybercab, as well as expanding on the Robotaxi program through the next 12 months:
“…as full-scale volume production begins with the autonomous and robotics roadmap…The company has started to test the all-important Cybercab in Austin over the past few weeks, which is an incremental step towards launching in 2026 with important volume production of Cybercabs starting in April/May, which remains the golden goose in unlocking TSLA’s AI valuation.”
Tesla analyst breaks down delivery report: ‘A step in the right direction’
Tesla has transitioned from an automaker to a full-fledged AI company, and its Robotaxi and Cybercab programs, fueled by the Full Self-Driving suite, are leading the charge moving forward. In 2026, there are major goals the company has outlined. The first is removing Safety Drivers from vehicles in Austin, Texas, one of the areas where it operates a ride-hailing service within the U.S.
Ultimately, Tesla will aim to launch a Level 5 autonomy suite to the public in the coming years.
