SpaceX highlights Crew Dragon SuperDraco thrusters as explosion investigation nears end

SpaceX has published a highlight reel touting “over 700 tests” of Crew Dragon’s SuperDraco abort thrusters at the same time as the company is about to close a failure investigation into a Dragon capsule’s April explosion, pinned primarily on abort-related hardware.

According to a September 6th meeting of NASA’s Aerospace Safety Advisory Panel (ASAP), SpaceX has nearly completed the ‘fault tree’ of Crew Dragon’s explosion, a term used to describe the process of analyzing telemetry and ruling out all possible failure modes. Once that tree is complete, the investigation can be finalized and SpaceX can implement all hardware and software changes needed to prevent similar failures from reoccurring. For the time being, this means that a 2019 launch of SpaceX’s inaugural crewed Dragon is almost certainly not in the cards, although early 2020 is still looking promising.

On April 20th, SpaceX was extremely quick to acknowledge that an anomaly had occurred during a planned static fire of flight-proven Crew Dragon capsule C201, recovered just one month prior after a flawless orbital launch debut. Soon after, an extremely low-quality video of a livestream of the static fire attempt was leaked, revealing that the capsule suffered a catastrophic explosion just moments before the ignition of its eight SuperDraco thrusters.

Incredibly, one of Crew Dragon C201’s SuperDraco ‘powerpacks’ (a pair of engines) was not only recovered intact after the explosion but static-fired at SpaceX’s McGregor, TX test facilities. A bit less than three months after the explosion, SpaceX and NASA officials hosted a press conference in July 2019 to discuss preliminary results from their joint Crew Dragon failure investigation. Some work remained to rule out other possibilities but NASA and SpaceX were confident enough to conclude that an exotic interaction between SuperDraco propellant and a leaky titanium valve likely triggered the explosion.

According to ASAP, SpaceX and NASA still have work to do before the investigation can be concluded, describing it as “nearly complete”. Additionally, the ASAP meeting continued what feels like an increasingly myopic focus on SpaceX’s carbon overwrapped pressure vessels (COPVs), used to store high-pressure helium on Falcon 9 and Heavy. COPVs have been partial causes of both of Falcon 9’s two operational failures, explaining NASA’s apparent prioritization of its certification.

Unspecified issues with parachutes were also raised for both Commercial Crew spacecraft, continuing a years-long trend of parachutes and COPVs taking up the majority of ASAP’s attention in public meetings. Boeing and SpaceX continue to test their parachute systems, both well into dozens of distinct tests after something like two years of concerted attempts to satisfy NASA requirements.

SpaceX has already demonstrated a successful orbital launch, reentry, parachute deployment, and splashdown during Crew Dragon’s March 2019 Demo-1 launch, as well as 18 successful Cargo Dragon parachute recoveries in the last seven years. Cargo Dragon did suffer one anomalous splashdown in 2018, but its partially redundant set of chutes still permitted a gentle and intact recovery.

Nevertheless, it appears that SpaceX and Boeing will have to continue performing parachute tests for the indefinite future. Boeing’s next milestone – an uncrewed orbital test flight (OTF) comparable to SpaceX’s Demo-1 mission – is expected to launch no earlier than October 28th according to Russian space industry sources. SpaceX’s next Crew Dragon milestone will be the spacecraft’s in-flight abort (IFA) test, scheduled no earlier than November 2019.

Elon Musk’s artificial intelligence company xAI has leased a full floor at Lincoln Square South in downtown Bellevue, WA, as per city permit filings. 

The lease places xAI’s new office in one of the region’s fastest-growing tech hubs.

Public records indicate that xAI leased roughly 24,800 square feet in Lincoln Square South. The location was previously occupied by video game company Epic Games. Lincoln Square South is part of the Bellevue Collection, which is owned by Kemper Development Co.

The lease was first referenced in January by commercial real estate firm Broderick Group, which noted that an unnamed tenant had secured the space, as stated in a report from the Puget Sound Business Journal. Later filings identified xAI as the occupant for the space.

xAI has not publicly commented on the lease.

xAI hinted at plans to open an office in the Seattle area back in September, when the startup posted job openings with salaries ranging from $180,000 to $440,000. At the time, the company had narrowed its location search to cities on the Eastside but had not finalized a lease.

xAI’s Bellevue expansion comes as Musk continues consolidating his businesses. Last week, SpaceX acquired xAI in a deal that valued the artificial intelligence startup at $250 billion. SpaceX itself is now valued at roughly $1.25 trillion and is expected to pursue an initial public offering (IPO) later this year.

Musk already has a significant presence in the region through SpaceX, which employs about 2,000 workers locally. That initiative, however, is focused largely on Starlink satellite development.

Bellevue has increasingly become a center for artificial intelligence companies. OpenAI has expanded its local office footprint to nearly 300,000 square feet. Data infrastructure firms such as Crusoe and CoreWeave have also established offices downtown.

SpaceX blocks unauthorized Starlink terminals used by Russian troops

Ukrainian officials confirmed that Starlink terminals believed to be used by Russian troops were disabled after coordination with SpaceX.

SpaceX has taken steps to block unauthorized use of its Starlink satellite internet network, a move Ukrainian officials stated is already disrupting Russian military communications. 

Russian units lose a key communications tool

As per a report from The Guardian, Ukrainian defense officials have confirmed that Starlink terminals believed to be used by Russian troops were recently disabled after coordination with SpaceX. The move reportedly affected frontline communications and drone operations, especially in areas where traditional military radios are unreliable or easily jammed.

For months, Russian units had relied on large numbers of illicitly obtained Starlink terminals to stay connected along the front. The satellite internet service allowed faster coordination and more precise drone use for Russian forces.

Several Russian military bloggers close to frontline units have acknowledged the impact of the Starlink shutdown, with some describing sudden connectivity problems in the satellite internet service.

Russia lacks comparable replacement

Russia does not have a satellite internet system that matches Starlink’s speed, coverage, and ease of deployment. Alternatives such as fiber-optic lines, short-range wireless links, and digital radio systems take longer to install and work inadequately for fast-moving units.

Russia does operate limited satellite communications through state-linked providers, but those systems rely mainly on geostationary satellites, which are notably slower. Coverage is uneven, and data capacity is far lower than Starlink’s low-Earth-orbit network.

For now, Ukraine has stated that it has introduced a verification system that allows only approved Starlink terminals to connect. Devices believed to be linked to Russian forces are blocked from the network. That being said, Ukrainian officials have also claimed Russian units are trying to work around the restrictions by asking civilians to register Starlink terminals in their names.

Tesla Semi pricing revealed after company uncovers trim levels

This is a step up from the prices that were revealed back in 2017, but with inflation and other factors, it is no surprise Tesla could not come through on the numbers it planned to offer nine years ago. When the Semi was unveiled in November 2017, Tesla had three pricing levels:

Tesla Semi pricing appears to have been revealed after the company started communicating with the entities interested in purchasing its all-electric truck. The pricing details come just days after Tesla revealed it planned to offer two trim levels and uncovered the specs of each.

After CEO Elon Musk said the Semi would enter volume production this year, Tesla revealed trim levels shortly thereafter. Offering a Standard Range and a Long Range trim will fit the needs of many companies that plan to use the truck for local and regional deliveries.

Tesla Semi lines up for $165M in California incentives ahead of mass production

It will also be a good competitor to the all-electric semi trucks already available from companies like Volvo.

With the release of specs, Tesla helped companies see the big picture in terms of what the Semi could do to benefit their business. However, pricing information was not available.

A new report from Electrek states that Tesla has been communicating with those interested companies and is pricing the Standard Range at $250,000 per unit, while the Long Range is priced at $290,000. These prices come before taxes and destination fees.

This is a step up from the prices that were revealed back in 2017, but with inflation and other factors, it is no surprise Tesla could not come through on the numbers it planned to offer nine years ago. When the Semi was unveiled in November 2017, Tesla had three pricing levels:

  • $150,000 for a 300-mile range version
  • $180,000 for a 500-mile range version
  • $200,000 for a limited “Founders Series” edition; full upfront payment required for priority production and limited to just 1,000 units

Tesla has not officially released any specific information regarding pricing on the Semi, but it is not surprising that it has not done so. The Semi is a vehicle that will be built for businesses, and pricing information is usually reserved for those who place reservations. This goes for most products of this nature.

The Semi will be built at a new, dedicated production facility in Sparks, Nevada, which Tesla broke ground on in 2024. The factory was nearly complete in late 2025, and executives confirmed that the first “online builds” were targeted for that same time.

Meaningful output is scheduled for this year, as Musk reiterated earlier this week that it would enter mass production this year. At full capacity, the factory will build 50,000 units annually.
