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 Boring Company’s newest Vegas Station has a permit quietly waiting behind it
Sahara Las Vegas opened a new Vegas Loop station, joining an exclusive two resort transit club.
Sahara Las Vegas opened a new Vegas Loop station Thursday, giving The Boring Company’s underground transit system its northernmost stop yet on the Strip. The station sits at Sahara’s Paradise Road entrance, on the southeast corner of Las Vegas Boulevard and Sahara Avenue, and connects riders to the Las Vegas Convention Center, other Strip resorts on the network and, eventually, Harry Reid International Airport.
The addition makes Sahara the second resort, after Fontainebleau opened its own station in January, to get a stop built at street level rather than tucked into the property itself. Sahara now joins Westgate as the only two Strip resorts offering both a Vegas Loop station and a stop on the Las Vegas Monorail, giving guests two separate ways to get around without leaving the property.
The Boring Company just doubled its tunneling power in Nashville
The bigger news buried in Thursday’s announcement is what comes next. Boring Company has already secured its first permit to tunnel north of Sahara Avenue, extending the network beyond where it currently ends, even though permits to push the Loop toward downtown Las Vegas still haven’t been granted. Crews are also working on a two mile dual tunnel line running from Westgate to a planned station at 4744 Paradise Road, just north of Tropicana Avenue, that Las Vegas Convention and Visitors Authority CEO Steve Hill has said the company hopes to open in time for November’s Las Vegas Grand Prix.
Ridership has grown alongside the buildout. The Loop moved roughly 82,000 passengers during CONEXPO in early March, a total the company highlighted on its own X account at the time, and the system has now carried more than 4 million passengers through 11 open stations since it began running in 2021. The airport connector tunnels, meant to give the Loop a direct link to Harry Reid, have slipped past their original first quarter target and remain under construction, with Boring Company director Mike Baier saying that a full opening is still a few months out.
For Sahara, the calculation is straightforward. Convention traffic drives a large share of Loop ridership, and a station at the property’s front door gives conventiongoers one more reason to book rooms on the Strip’s north end instead of closer to the convention center itself.
Elon Musk
Tesla’s mysterious Robovan makes a sneak peek with Optimus in Terafab video
Elon Musk shared a new Terafab video showing Optimus, Robovans, and a stunningly futuristic campus.
Elon Musk posted a new video of Terafab on X Thursday morning, and the most eye-catching details in it were not the building itself, but two products still awaiting production: Optimus and the Robovan.
The concept render, credited to SpaceX, shows Optimus robots working the grounds of the roughly 2.5-mile-long facility planned for the Gibbons Creek site in Grimes County, while a Robovan glides along an elevated roadway cutting through the building itself, sharing the frame with a Tesla Semi and a Cybercab.
Robovan is the boxy, driverless people and cargo mover Musk unveiled alongside Cybercab at Tesla’s “We, Robot” event in October 2024. He pitched it as a way to move up to 20 passengers at once, or handle freight instead, at a target cost he claimed could fall under a dollar a mile, with no steering wheel or pedals, the same layout as Cybercab. Nearly two years later, Robovan still has no confirmed production timeline and has not shown up in any factory footage, which makes Thursday’s render one of the only recent looks at the vehicle in any form.

Optimus has moved further along. Tesla began converting Fremont’s old Model S and Model X assembly line into a Gen 3 Optimus production line earlier this year, and Musk visited the site on July 1 to mark the changeover. A second, larger Optimus plant is under construction at Giga Texas, targeting volume production in summer 2027 and eventual capacity of 10 million units a year. Tesla AI lead Ashok Elluswamy said this month the robot has “big shoes to fill” in replacing the S and X line, while Musk has repeatedly called Optimus the company’s biggest product of any kind, with a long-term price he has pegged between $20,000 and $30,000.

“Terafab Texas will be the largest and most valuable building on Earth by far,” Musk wrote alongside the clip. “And it will be stunningly beautiful.”
One quote post summed up the reaction: “Futuristic scene with RoboVan + Cybercab + Tesla Semi + Optimus.”
Beyond the vehicles, the architecture wrapped around them stands out too. The building’s facade is canted at sharp angles, with illuminated horizontal bands running through what appears to be a multi level interior visible from outside. Below the elevated roadway, pedestrians walk along a plaza next to a reflecting pool, and the skyline behind the campus is dotted with angular spires that read more like sculpture than infrastructure, a departure from the strictly utilitarian look of Gigafactory Texas or Starbase.
The timing tracks with what Terafab representative Riley Trennell told Grimes County residents on Wednesday, when he said renderings of the facility would be released “within days.” Musk’s post followed less than 24 hours later, and Texas Governor Greg Abbott’s office sent out its own release Thursday confirming the project. As Teslarati reported this morning, Terafab’s tax abatement agreements with Grimes County are now signed and active, and SpaceX has sent the county its first $10 million payment under that deal. The dollar figure tied to this phase of construction, per Reuters, is $16.8 billion, one of the first hard capital expenditure numbers attached to Terafab since Musk unveiled the joint Tesla-SpaceX-xAI venture in March.Reaction on X ranged from enthusiastic to skeptical. “God Bless Texas! Everything is bigger and better in Texas!” one reply read. Another was more measured: “Terafab in a decade…..”
Whether the finished building matches the render is a separate question from whether Musk wanted people talking about the render itself. Less than a day after posting, the video had already crossed 5.5 million views.

Tesla Cybertruck production snaps back after ugly supplier fight
Cybertrucks are piling up again at Giga Texas after Tesla’s court win against a parts supplier.
Cybertruck production at Giga Texas is showing its first visible recovery since Tesla sued a supplier last month over withheld manufacturing tooling.
Aerial observer Joe Tegtmeyer flew over the Austin factory Wednesday morning and counted roughly 100 or more Cybertrucks filling the outbound lot, a sharp jump from the thin numbers seen in recent weeks. The flyover came a day after a judge granted Tesla a temporary restraining order against Angstrom Automotive Group, the parts supplier at the center of the dispute.
Tesla filed an emergency lawsuit in late July after Angstrom told the automaker it planned to close the Troy, Texas facility where Tesla’s die-cast tools, trim dies and other Cybertruck stamping equipment were housed. According to Tesla’s complaint, a shipment of 700 finished parts never left the building, and when Tesla sent representatives to retrieve its equipment, accompanied by law enforcement, they were turned away. Angstrom allegedly then asked for an extra $250,000 a week to keep operating, which Tesla’s filing described as holding its own property for ransom.
TESLA: U.S. District Judge Christopher R. Wolfe of the U.S. District Court for the Western District of Texas, Waco Division granted Tesla a Temporary Restraining Order and Writ of Replevin in its dispute with Angstrom Automotive (Case No. 6:26-cv-00477).

The restraining order gives Tesla immediate right of entry to Angstrom’s facility to recover the tooling. It is temporary, with a fuller hearing still to come, but the speed of Wednesday’s rebound suggests the Angstrom shortage was indeed the main bottleneck limiting Cybertruck output. Outbound lot counts are an imperfect measure of actual production, since finished trucks can sit for days before shipping, but a lot that full after a lean stretch is a meaningful signal.
Cybertruck output at Giga Texas has fluctuated all year as Tesla worked through supply issues and introduced new trims, including a cheaper Dual Motor AWD version that drew strong early demand.
