SpaceX test-fires Falcon 9 for expendable Block 5 launch as bad weather threatens delays
SpaceX has fired up twice-flown Falcon 9 booster B1047 ahead of Block 5’s second expendable launch ever, but the company avoided its usual confirmation that a ‘quick look’ data analysis shows the vehicle as ready for launch.
Aside from the unusual phrasing of SpaceX’s static fire confirmation, stating instead that the company “is assessing data”, the weather forecast for the launch of AMOS-17 is looking about as dreary as it was during SpaceX’s most recent July 25th launch, CRS-18. CRS-18 was scrubbed once before the instantaneous launch window luckily coincided with an only partially metaphorical gap in the clouds. However, scheduled to lift off no earlier than 6:52 pm EDT (22:52 UTC), August 3rd, the AMOS-17 commsat launch features a comparatively luxurious ~90-minute window, giving SpaceX a much better shot at ‘threading the needle’.
Still, as indicated in the tweet above, the combination of a horrible weather forecast (70% chance of weather violation on Aug. 3, 60% on Aug. 4), uncertainty surrounding Falcon 9’s static fire test results, and the gravity of this particular launch all suggest that delays are likely.
With most things in rocketry, the adage, “Better late than never!” almost invariably holds true when dealing with late-stage launch vehicle processing, and SpaceX will be taking that to the extreme with this launch for reasons that will become clear. If SpaceX can avoid the growing probability of minor delays, generally an annoying non-issue more than anything else, customer Spacecom will certainly be appreciative, but the most important thing is ensuring the safe orbital delivery of AMOS-17.
Weighing roughly 6500 kg (14,300 lb) fully-fueled, AMOS-17 is a relatively large geostationary communications satellite built by Boeing and, practically speaking, is meant to replace Amos-6, an Israeli-built satellite that was destroyed in September 2016 during a catastrophic Falcon 9 failure. Spacecom effectively took the insurance funds it received from the loss of Amos-6, purchased AMOS-17 via Boeing, and then chose a contract option that gave the company a free Falcon 9 launch instead of taking a cash payout of $50M.
Be it financial necessity or a genuine decision to trust SpaceX that led Spacecom to manifest its replacement satellite on Falcon 9, a second failure and loss of payload (AMOS-17) during this launch would be a spectacular embarrassment and a major wound to SpaceX’s growing reputation as a reliable launch provider. If there is any launch in particular that SpaceX explicitly wants to avoid a failure on, it’s probably AMOS-17.
Perhaps to this end, SpaceX has actually chosen – presumably at the request or suggestion of Spacecom – to expend a Falcon 9 Block 5 booster in support of the AMOS-17 launch. Confirmed by SpaceX to be B1047.2, the company will preclude a landing attempt and instead sacrifice a booster that might otherwise fly a dozen more launches to give Spacecom a larger safety margin and help AMOS-17 start serving customers as quickly as possible. The sooner AMOS-17 can reach its final geostationary orbit (GEO), the sooner Spacecom can begin generating revenue from the satellite.
Finally, SpaceX fairing recovery vessel GO Ms. Tree (formerly Mr. Steven) has just departed Port Canaveral (c. August 1st) and is headed nearly 1000 km (600 mi) east into the Atlantic Ocean for what could be the ship’s second successful fairing catch ever. Stay tuned as SpaceX provides updates and we near AMOS-17’s tentative launch date.

The Tesla Semi was spotted mounted with ground truth validation equipment as the company nears its looming launch. The Semi is Tesla’s Class 8 all-electric truck, and has been utilized in its earlier stages by many companies like PepsiCo. and Frito-Lay, who have been using it in a pilot program.
The Semi was spotted in Sunnyvale, California, and sports a typical ground truth validation unit that Tesla routinely uses on its vehicles. Ground truth validation is essentially the process of training supervised algorithms to ensure they can perform reliably. Tesla typically performs this on vehicles that are being released soon:
Spotted the new semi adorned with ground truthing equipment. Haven’t seen anyone post this so figured I’d share.

The Semi being spotted with this type of validation rig is important because it means the company is working on solidifying a Full Self-Driving model for its commercial vehicle offering. This would be a massive development for not only Tesla but also the logistics industry as a whole.
There are strict regulations on driving hours for commercial truck drivers, and autonomy is a way to potentially combat these issues. FSD is already a widely effective way that owners of typical passenger vehicles take stress out of travel. Even launching a semi-autonomous platform for truck drivers to use to increase safety, reduce fatigue, and increase productivity would be a huge development.
Tesla Semi gets strange-but-understandable comparison from Jay Leno
The Semi has already proven to be an ideal solution for companies that use commercial logistics. It has increased efficiency and reduced operating costs for many companies that have been able to use it in pilot programs.
There are expected to be some bumps along the way. Tesla saw some challenges with FSD on the Cybertruck, as it had never had a vehicle with cameras at that height, so some of the features with FSD were not immediately available. Just a week ago, Tesla launched Actually Smart Summon (ASS) for Cybertruck, nearly three years after the vehicle was first delivered to customers.
President Donald Trump unveiled an upgraded Boeing 747-8 at Joint Base Andrews on June 19, 2026, describing the Qatar-gifted aircraft as an interim Air Force One equipped with advanced communications systems, including Starlink, Elon Musk’s SpaceX satellite internet service.
The plane, valued at around $400 million and modified for presidential use, serves as a bridge until the delayed VC-25B replacements arrive. Trump highlighted its luxury features and new technology during remarks to service members.
Trump stated:
“We have communication equipment up there that nobody’s ever seen before. It’s the highest level and, uh, including Starlink. My friend Elon is going to be very happy, but, uh, Starlink and we have, uh, four or five different sets of double and triple communications like people haven’t seen.”
He added:
“And it represents what can happen with hard work, innovation, and aggressive timelines because we did this quickly and yet there’s never been communication like is on this plane.”
🚨 President Trump confirmed today that the new Air Force One is equipped with Starlink:

The aircraft features a redesigned red, white, and blue livery and has been outfitted with Starlink satellite connectivity alongside other secure systems.
Trump praised the plane’s uniqueness, calling it among the world’s most luxurious. The gift from Qatar and subsequent modifications have drawn attention, with the jet positioned as a solution for presidential travel. It is expected to support operations, including potential ceremonial roles such as Fourth of July flyovers.
The event marked the formal introduction of the converted jet, which will help maintain capabilities while the primary Air Force One fleet undergoes modernization. Defense observers note the inclusion of commercial satellite technology like Starlink as part of efforts to ensure resilient communications, crucial to keep the country running as the President is in the sky.
President Trump’s comments underscored appreciation for rapid upgrades and innovation in equipping the aircraft. The plane remains a U.S. government asset and is slated for eventual transfer related to presidential library purposes after its service.
Tesla just gave what is perhaps its biggest signal yet that the launch of the Cybercab, its autonomous ride-hailing-geared car, is imminent.
The Cybercab has been spotted outside of Gigafactory Texas in massive numbers over the past few days, with hundreds of units being stored on property just days after the vehicle received a Certificate of Conformity from the EPA.
Today, things were a bit different.
Cybercabs spotted on Giga Texas property today had an addition: a Cybercab decal on the side, reminiscent of the “Robotaxi” ones that were placed on Model Ys just as the company launched its ride-sharing platform about a year ago.
Giga Texas drone operator Joe Tegtmeyer noticed the change today:
Tesla Cybercabs are now getting “Cybercab” logos on the side of them!

Tesla could be signaling that the Cybercab is preparing to enter the Robotaxi fleet in the coming weeks or months with this move. It seems more symbolic than anything; Tesla is ready to throw Cybercabs in the ride-hailing platform just as it did with Model Ys last year.
The addition of the Certificate of Conformity awarded to the Cybercab is another major factor working to Tesla’s advantage. The company now has permission from the EPA to allow the vehicle to operate on public roads and enter the chain of commerce. It’s officially street legal.

The big question that remains is whether Tesla will be able to operate the car without a safety monitor, especially considering it plans to put the car out there without a steering wheel or pedals. With the Cybercab only having a seating capacity of two, it is hard to believe Tesla will even consider putting a Safety Monitor in the car.
It did recently self-certify as Level 4 and has the ability to operate driverless vehicles in the State of Texas under a law that took effect on May 28. You can read more about that here:
Tesla’s Robotaxi dreams just took a massive step toward reality
We’d imagine Cybercabs will be on the roads as soon as July, but August will likely be a better estimate of when the car will be entered into the Cybercab fleet. It all depends at where Tesla is, as they’ve truly prioritized safety with the rollout of the Robotaxi platform.
