SpaceX’s Crew Dragon explosion investigation almost complete, says executive
Speaking at the 2019 AIAA Propulsion & Energy Forum, SpaceX Vice President of Build and Flight Reliability Hans Koenigsmann was significantly more confident that the company is just days or weeks away from wrapping up a serious Crew Dragon failure investigation.
On April 20th, flight-proven Crew Dragon capsule C201 experienced a catastrophic failure mode – largely a surprise to SpaceX – that completely destroyed the vehicle milliseconds prior to a planned static fire test. Given the obvious mortal danger such a failure would have posed to any crew aboard, SpaceX’s plans to conduct its first crewed Crew Dragon launch (Demo-2) in Q3 2019 were thrown out the window. Thankfully, Hans believes that SpaceX is just shy of concluding that investigation, “hopefully” permitting the launch of a critical abort test and Demo-2 before 2019 is out.
More specifically, Koenigsmann noted that SpaceX is currently planning to conduct a critical Crew Dragon in-flight abort (IFA) test in October or November, more or less in line with a recent report from NASASpaceflight.com that the test is targeted for November 11th, 2019. NASASpaceflight also confirmed that SpaceX still plans to fly Falcon 9 booster B1046.3 on the critical test flight, currently the only established plan to launch a thrice-flown booster, a potential first for SpaceX’s reusability program.
SpaceX’s IFA test is a continuation of the company’s suborbital Crew Dragon testing. Back in 2015, SpaceX successfully completed a pad abort test in which a low-fidelity Dragon mockup used its eight SuperDraco abort thrusters to replicate an escape from a rocket failure on the launch pad. SpaceX’s in-flight abort test will – like its namesake indicates – perform a similar test in flight, ensuring that Crew Dragon is able to safely escape from a failing Falcon 9 at Max Q, the point during launch where atmosphere-induced mechanical stress is at its peak.
In theory, demonstrating a successful pad and in-flight (Max Q) abort means that a given spacecraft is able to safely abort at all points during flight – from the pad all the way to orbit. It’s not clear if Crew Dragon is actually designed to be capable of what’s known as an “abort-to-orbit”, but the hardware is likely there if it’s needed.

On July 15th, Hans Koenigsmann and NASA Commercial Crew Program (CCP) manager Kathy Lueders went into significant detail with a preliminary Crew Dragon failure investigation update. They revealed that Crew Dragon’s April 20th explosion was traced to a likely mode, in which a “slug” of Dragon’s liquid oxidizer (nitrogen tetroxide, NTO) leaked and was subsequently smashed into a titanium valve by helium pressurized to several thousand PSI.
Said impact – effectively turning NTO into a bullet – thus created a spark in one or two ways: the titanium debris could have easily created sparks on its own, while NTO is also known to interact in violent and exotic ways with titanium under impact conditions. Either way, the fix is relatively simple (replace the valves and avoid titanium in the NTO pressurization system), but the fact that the design flaw existed in the first place serves as a much larger concern for the entirety of Crew Dragon’s joint SpaceX-NASA design and certification.
Ultimately, Hans seemed much more confident on August 19th than he was a month prior, indicating that the investigation is just shy of wrapping up. Once complete, SpaceX can complete the necessary modifications and get back on the saddle for Crew Dragon’s inaugural crewed launch and next abort test.

Elon Musk’s Boring Company opens Vegas Loop’s newest station
The Fontainebleau is the latest resort on the Las Vegas Strip to embrace the tunneling startup’s underground transportation system.
Elon Musk’s tunneling startup, The Boring Company, has welcomed its newest Vegas Loop station at the Fontainebleau Las Vegas.
The Fontainebleau is the latest resort on the Las Vegas Strip to embrace the tunneling startup’s underground transportation system.
Fontainebleau Loop station
The new Vegas Loop station is located on level V-1 of the Fontainebleau’s south valet area, as noted in a report from the Las Vegas Review-Journal. According to the resort, guests will be able to travel free of charge to the stations serving the Las Vegas Convention Center, as well as to Loop stations in Encore and Westgate.
The Fontainebleau station connects to the Riviera Station, which is located in the northwest parking lot of the convention center’s West Hall. From there, passengers will be able to access the greater Vegas Loop.
Vegas Loop expansion
In December, The Boring Company began offering Vegas Loop rides to and from Harry Reid International Airport. Those trips include a limited above-ground segment, following approval from the Nevada Transportation Authority to allow surface street travel tied to Loop operations.
Under the approval, airport rides are limited to no more than four miles of surface street travel, and each trip must include a tunnel segment. The Vegas Loop currently includes more than 10 miles of tunnels. From this number, about four miles of tunnels are operational.
The Boring Company President Steve Davis previously told the Review-Journal that the University Center Loop segment, which is currently under construction, is expected to open in the first quarter of 2026. That extension would allow Loop vehicles to travel beneath Paradise Road between the convention center and the airport, with a planned station located just north of Tropicana Avenue.

Tesla leases new 108k-sq ft R&D facility near Fremont Factory
The lease adds to Tesla’s presence near its primary California manufacturing hub as the company continues investing in autonomy and artificial intelligence.
Tesla has expanded its footprint near its Fremont Factory by leasing a 108,000-square-foot R&D facility in the East Bay.
The lease adds to Tesla’s presence near its primary California manufacturing hub as the company continues investing in autonomy and artificial intelligence.
A new Fremont lease
Tesla will occupy the entire building at 45401 Research Ave. in Fremont, as per real estate services firm Colliers. The transaction stands as the second-largest R&D lease of the fourth quarter, trailing only a roughly 115,000-square-foot transaction by Figure AI in San Jose.
As noted in a Silicon Valley Business Journal report, Tesla’s new Fremont lease was completed with landlord Lincoln Property Co., which owns the facility. Colliers stated that Tesla’s Fremont expansion reflects continued demand from established technology companies that are seeking space for engineering, testing, and specialized manufacturing.
Tesla has not disclosed which of its business units will be occupying the building, though Colliers has described the property as suitable for office and R&D functions. Tesla has not issued a comment about its new Fremont lease as of writing.
AI investments
Silicon Valley remains a key region for automakers as vehicles increasingly rely on software, artificial intelligence, and advanced electronics. Erin Keating, senior director of economics and industry insights at Cox Automotive, has stated that Tesla is among the most aggressive auto companies when it comes to software-driven vehicle development.
Other automakers have also expanded their presence in the area. Rivian operates an autonomy and core technology hub in Palo Alto, while GM maintains an AI center of excellence in Mountain View. Toyota is also relocating its software and autonomy unit to a newly upgraded property in Santa Clara.
Despite these expansions, Colliers has noted that Silicon Valley posted nearly 444,000 square feet of net occupancy losses in Q4 2025, pushing overall vacancy to 11.2%.

Tesla winter weather test: How long does it take to melt 8 inches of snow?
In Pennsylvania, we got between 10 and 12 inches of snow over the weekend as a nasty Winter storm ripped through a large portion of the country, bringing snow to some areas and nasty ice storms to others.
I have had a Model Y Performance for the week courtesy of Tesla, which got the car to me last Monday. Today was my last full day with it before I take it back to my local showroom, and with all the accumulation on it, I decided to run a cool little experiment: How long would it take for Tesla’s Defrost feature to melt 8 inches of snow?
Tesla’s Defrost feature is one of the best and most underrated that the car has in its arsenal. While every car out there has a defrost setting, Tesla’s can be activated through the Smartphone App and is one of the better-performing systems in my opinion.
It has come in handy a lot through the Fall and Winter, helping clear up my windshield more efficiently while also clearing up more of the front glass than other cars I’ve owned.
The test was simple: don’t touch any of the ice or snow with my ice scraper, and let the car do all the work, no matter how long it took. Of course, it would be quicker to just clear the ice off manually, but I really wanted to see how long it would take.

Observations
I started this test at around 10:30 a.m. It was still pretty cloudy and cold out, and I knew the latter portion of the test would get some help from the Sun as it was expected to come out around noon, maybe a little bit after.
I cranked it up and set my iPhone up on a tripod, and activated the Time Lapse feature in the Camera settings.
The rest of the test was sitting and waiting.
It didn’t take long to see some difference. In fact, by the 20-minute mark, there was some notable melting of snow and ice along the sides of the windshield near the A Pillar.
However, this test was not one that was “efficient” in any manner; it took about three hours and 40 minutes to get the snow to a point where I would feel comfortable driving out in public. In no way would I do this normally; I simply wanted to see how it would do with a massive accumulation of snow.
It did well, but in the future, I’ll stick to clearing it off manually and using the Defrost setting for clearing up some ice before the gym in the morning.
Check out the video of the test below:
