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.

Watch Tesla’s “guardian angel” FSD feature take over for collision evasion

Published

on

By

Tesla’s Automatic Collision Evasion feature can be seen in one of the first owner videos of it in action.

Tesla owner Spencer (@scotsrule08) posted on Monday that the feature “worked flawlessly,” saying FSD reengaged itself just as he was about to hit a curb. Ashok Elluswamy, who leads Tesla’s AI team, shared the clip and wrote, “A guardian angel always looking out for you.”

The video arrives in the middle of a staged rollout. Tesla first shipped Automatic Collision Evasion with FSD (Supervised) v14.3.9 in software update 2026.27.6 earlier this month, which Teslarati covered as it reached cars. Update 2026.27.10, which began going out on September 19, carried the feature improvements with FSD v14.3.10, according to release notes tracked by Not a Tesla App. The newer 2026.27.11 build is now reaching another wave of vehicles.


The feature only runs on HW4 vehicles, and it requires an active FSD purchase or subscription with both FSD (Supervised) and Automatic Emergency Braking enabled. HW3 owners receive FSD v14.2 Lite in the same updates, but that build does not include collision evasion.

Tesla’s release notes describe two triggers. The first is an imminent frontal collision that braking alone may not prevent, in which case the car can activate FSD to steer, brake or accelerate around the hazard. That scenario is limited to highways below 85 mph, with no pedestrians or cyclists detected and no slippery road surface. The second covers a driver who appears inattentive, such as reaching into the back seat, or who seems to have switched off FSD by accident. Spencer’s curb clip appears to fall into that second category.

Tesla plans big safety improvements for Full Self-Driving v15

Once the system takes over, the accelerator is muted and light brake input will not cancel the maneuver. Drivers need to apply firm, deliberate steering force to take back control, and the car chimes to hand control back once the danger has passed.

Elluswamy recently noted that earlier hazard prediction, faster reaction time and better collision avoidance would arrive with FSD v15, the next major version.

Tesla Roadster event gets delayed due to unfavorable weather

Published

Credit: Tesla

Tesla is delaying its event for the Roadster, moving it from this Thursday, October 1, to Thursday, October 15, due to unfavorable weather.

The company has said it has been tracking the weather for this Thursday closely with local meteorologists, and because the event can only be held outside, Tesla is making the call to delay it:

“We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule. New date is October 15. Additional details to follow.”

We are sure that this is bringing back PTSD for some Tesla fans, and we know it is not ideal, but this also reveals some things about the event. Tesla said that this can only be held outdoors, meaning it bodes well for the rumors that the vehicle could potentially hover.

Some believe that this was essentially confirmed by the FAA airspace restriction they were granted, but this could have been for a drone show or to keep drones from spying on the event.

Tesla Roadster is available for order once again following brief hold

The Roadster event has been long-awaited, and it is unfortunate that the weather is going to keep us all waiting a little bit longer.

The Tesla Roadster will be unveiled in Waco, Texas.

SpaceX turned a heralding moment for Starship into its greatest

Starship reached orbit despite losing an engine, deployed 26 Starlink V3 satellites on Flight 14.

SpaceX’s Starship reached orbit for the first time on Monday, and for a few nail-biting minutes it looked like it wouldn’t. During ascent on Flight 14, one of Ship 41’s six Raptor engines shut down early, and SpaceX’s livestream host Dan Huot told viewers the team had decided not to commit to orbit. Minutes later, after what Huot described as a lot of conversation in the control room, the final poll came back in favor, and a roughly 19 second burn of a single Raptor pushed the ship into orbit about 170 miles up.

The reversal matters because SpaceX had written the exit ramp into the mission plan. The company said it would only fire the orbital insertion burn if flight controllers confirmed enough backup hardware remained for the deorbit burn, a condition Teslarati laid out ahead of the flight. Losing an engine was exactly the scenario that rule was built for.

Pressing forward fits Elon Musk’s history. Falcon 1 failed three straight times before its fourth launch reached orbit in 2008, with SpaceX nearly out of money, and Starship was developed by flying prototypes until they broke. What changed this year SpaceX going public, and with $SPCX sliding below its IPO price in July when Flight 13 slipped, the short interest climbed significantly, as Teslarati reported at the time. A Starship potentially lost today with revenue generating next-gen Starlink satellites aboard would have landed directly on shareholders.

That pressure showed up after orbit. SpaceX cut a flight planned to last nearly 10 hours to about three, moving splashdown from west of Chile to the North Pacific near Hawaii. SpaceX gave no reason, though Musk said this month the company was being extremely cautious about debris risk. The single Raptor for deorbit worked, and Ship 41 completed its flip and landing burn before breaking apart in the water, an outcome SpaceX expected. Musk has structured SpaceX’s governance to shield long term bets from market pressure.

The payload is the bigger business story. Musk posted that all 26 Starlink V3 satellites deployed and are “operating nominally.” Each V3 is rated for about 1 Tbps of downlink and 160 Gbps of uplink, so this single launch adds roughly 26 Tbps, about 10 times what a Falcon 9 load of V2 Mini satellites adds. The V3 is too large for Falcon 9, making Starship the only vehicle that can build out the planned 100,000 satellite constellation, at up to 60 per flight once it reaches routine service. Unlike the 20 V3 units on Flight 13, which reentered on a suborbital path, these will raise their orbits and could begin serving customers within weeks and bring in hundreds of millions of additional dollars in projected Starlink revenue.

SpaceX has already begun winding down Falcon 9 Starlink launches from Florida in favor of Starship. Reported targets put Flight 15 as early as October 19, leaving about three weeks to diagnose Monday’s engine shutdown before the next orbital attempt.
