First reported by NASASpaceflight.com, SpaceX has delayed Falcon 9 B1047.2’s third and final launch due to issues with the booster’s Merlin 1D engines. Fascinatingly, the company has decided to perform an unprecedented second static fire test before going ahead with the launch of Spacecom’s AMOS-17 communications satellite.

As a result, AMOS-17’s nominal August 3rd launch date is now off the table as SpaceX prepares for a second Falcon 9 wet dress rehearsal (WDR) and booster ignition test. Assuming the issue(s) observed after the first static fire test on July 31st are fixed after test #2, scheduled no earlier than Friday, August 2nd, SpaceX will reconfirm Falcon 9’s new AMOS-17 launch date. According to payload manufacturer and launch liaison Boeing, AMOS-17 is now scheduled to lift off no earlier than Monday, August 5th.

In the ~10-year history of Falcon 9, a back-to-back preflight static fire of the same booster is unprecedented. Every SpaceX launch in history has been preceded by an on-pad wet dress rehearsal (WDR) and static fire test. This involves filling the integrated booster and upper stage (and payload, sometimes) to flight-levels with propellant and fluids (RP-1, LOx, helium, nitrogen, TEA/TEB) and performing a launch countdown that is a carbon copy up to the point of liftoff.

Including a brief ignition of the booster’s main engines, this test serves as a full-fidelity rehearsal that helps SpaceX empirically determine whether the rocket and launch pad are ready for flight. Of note, SpaceX’s wealth of integrated systems testing has uncovered hardware and software bugs that can then be fixed without adding any risk to expensive customer payloads.

SpaceX’s workhorse Falcon 9 has scrubbed and delayed pre-launch static fires many, many times in the past but a double-header static fire test with a flight-ready rocket is simply unprecedented. According to SpaceX, the decision to perform a second static fire prior to launching AMOS-17 was made because of a presumably faulty valve or valves associated with the booster’s (B1047) Merlin 1D propulsion, featuring nine semi-identical engines capable of producing more than 7600 kN (1.71m lbf) of thrust.

SpaceX says the questionable valve or valves were replaced less than 24 hours after the first static fire was completed and NASASpaceflight.com reports that the second static fire will occur no earlier than Friday, August 2nd. According to Boeing, a good second static fire will push the launch to NET August 5th, likely featuring a similar ~90-minute window in the late evening (EDT).

Tesla Model Y L gets suspension complaints in over odd issue China

Published

The Tesla Model Y L is arguably the most hyped trim of the all-electric crossover, other than the Performance configuration that comes with white-knuckle speed and sports car-level handling.

However, it is not all perfect. Tesla owners in China who took delivery of the Model Y L, denoted with an L to highlight its longer wheelbase, are experiencing what they are referring to as “collapsing” of the rear wheels, as suspension issues appear to be an issue with some of the builds.

The gap between the wheel arch and tire has narrowed to the point that “not even a single finger” could fit, according to a report from Car News China. The failures are not tied to a specific mileage, as one owner said that after just 9,000 kilometers (5,600 miles), they noticed the suspension issue when their car was fully loaded.

Another one had the issue at 30,000 kilometers (18,640 miles) and noticed that the wheel gap shrank to two fingers, so not as drastic as the person who reported a similar issue at 9,000 km.

Tesla Model Y L is gaining momentum in China’s premium segment

Along with the visual recognition of the issue, others are saying the sagging is causing abnormal wear on the inside of the tires. Extra weight and instant torque already provide additional stress on the tires in electric vehicles during normal operation, so it is no surprise that this is another complaint.

There has been no recall issued by Tesla, and the company has not yet publicly acknowledged the issue.

Some are suggesting that owners use a “finger test” to self-diagnose whether there is an issue with the suspension. There should be four fingers between the tire and the wheel well; anything less than that starts to get dicey.

Tesla Cybercab event gains steam ahead of massive launch

Tesla is starting to truly tease and hype its groundbreaking Cybercab event, which takes place tomorrow in Austin, Texas. It will be the first time members of the public will be able to ride in a Cybercab, a vehicle without any manual controls, on public roads.

Tesla has been dropping some hype on X over the past several days, but this morning, the excitement has truly started to build up for the event. Although Cybercab has been unveiled before, this is truly Tesla’s announcement that it is ready to start offering autonomous rides for public passengers in its new ride-hailing-geared vehicle for the first time.

The hype has started with a variety of different social media posts that are a true indication that Tesla is preparing for something big. Teasing so much of the potential of Cybercab, including its ability to truly revolutionize how people hail rides for local travel, is what the big idea for the event entails. The time that many Tesla owners, fans, and investors have been waiting for is potentially here:

The event has remained slim on details. Even invitees are still awaiting true details about what the event will entail, where they’ll go, and what is in store for the evening. This is pretty typical for an event run by Tesla; they keep things under wraps for the most part until the very last minute.

However, there is no secret about what the real intention of Tesla is for this event: it is going to be a huge reveal party for a vehicle that has no steering wheel and no pedals. It is a truly massive step for the company moving forward.

Speculation persists as to whether this is going to be an event that simply announces that rides will begin with the Cybercab, or it will be something more substantial. Tesla has said in the past that they plan to sell the Cybercab to the general public in what could become a great way to earn passive income by adding it to a more global fleet of Robotaxi-geared vehicles.

Tomorrow, the show begins in Austin, and the Cybercab goes live at some capacity; we just don’t know exactly how quite yet.

SpaceX tells the FCC that Starship Flight 14 is going to orbit

SpaceX filed with the FCC for Starship Flight 14, its first true orbital launch attempt.

Published

By

SpaceX has asked the Federal Communications Commission for permission to fly Starlink terminals during Starship’s fourteenth flight test, and the filing lays out a genuine trip to orbit, something the program has never attempted.

Every Starship flight so far, including Flight 13’s successful splashdown in the Indian Ocean on July 24, has flown a suborbital arc that ends with the ship reentering the atmosphere within the same hour it launches. The FCC paperwork describes a mission profile built around an actual orbital insertion instead.

The payload is the other half of the story. Flight 13 carried 20 production Starlink V3 satellites, but because that mission never reached orbit, the satellites reentered along with the ship rather than joining the constellation, something Teslarati covered in detail after SpaceX released footage shot from one of those satellites as it drifted away from Starship in space. Flight 14 is designed to close that gap. If the orbital insertion holds, the roughly 20 V3 satellites onboard would separate into an operational orbit and could eventually go into service, each one rated for about 1 terabit per second of downlink capacity by SpaceX’s own account.

SpaceX announces new Starbase for ‘thousands of Starship launches annually’

Elon Musk first flagged the orbital attempt during SpaceX’s August 4 earnings call, the company’s first as a public entity following its June IPO under the ticker SPCX. He also floated catching the ship with the Starbase tower on the same flight, an idea he walked back on August 20, saying the catch attempt would more likely come “in a few months,” as Teslarati reported at the time. Flight 14 will instead target a splashdown for the ship in the Indian Ocean, the same recovery method used since Flight 12.

Hardware has been catching up to the ambition. Booster 21 completed a full 33-engine static fire on August 28, and Ship 41 finished its own six-engine test the week before. An airspace briefing circulated to pilots on August 20 listed September 15 as the target date, later than the end of August window Musk mentioned on the earnings call, though SpaceX has not confirmed a launch date publicly and Starship schedules routinely slip while hardware and FAA paperwork line up.

The FCC filing itself does not guarantee a launch date. It covers communications authority, and not flight readiness, considering SpaceX still needs Ship 41 fully stacked and cleared by the FAA before Flight 14 can fly. But the filing is a real marker of intent and it puts a specific regulatory process behind what had so far only been Musk’s word on the earnings call.
