SpaceX’s second dedicated USAF mission targets Dec. 2018 for GPS satellite launch

Published

One of a number of 2018 SpaceX missions pushed into this year’s fourth quarter, SpaceX’s second-ever dedicated US Air Force payload is tracking towards a tentative mid-December launch, hopefully kicking off the deployment of the first ten third-generation GPS (Global Positioning System) satellites.

Set to launch the first and second GPS satellites on upgraded Falcon 9 Block 5 rockets, SpaceX and the USAF could potentially decide to fly one or several of the company’s contracted GPS missions on flight-proven boosters.

Designed and built by Lockheed Martin, each of the first group of a dozen satellites will weigh approximately 3900 kg (8900 lb) and will be placed in a circular orbit 20,000 km (12,500 mi) above Earth’s surface, resulting in one completed orbit every 12 hours. Both as a result of each satellite’s significant mass and orbit requirement and the desire to spread risk over multiple launches, the first eight GPS Block IIIA spacecraft will ride into space on their own dedicated launch vehicles – five aboard Falcon 9, one on a ULA Delta IV, and the rest yet to be determined.

SpaceX’s Falcon 9 was certified to launch national security-sensitive USAF payloads in May 2015 after spending years fighting for the reintroduction of competition into the Department of Defense’s rocket launch procurement apparatus, killed back in the mid-2000s when Lockheed Martin and Boeing merged their space subsidiaries into the United Launch Alliance despite protests from NASA and some in the DoD.

That launch is now aiming for December 15th, 2018, although such a specific date nearly three and a half months out should be treating as purely for planning purposes. Originally planned to launch on a ULA Delta IV rocket, the USAF decided (for unknown reasons) to switch the order of launch, making SpaceX the launch provider for the first and second spacecraft, with ULA following up on the third launch. In March 2018, SpaceX was additionally awarded one more GPS IIIA launch with the option for two more, at a total contract cost of roughly $290 million or ~$97 million apiece. Of the remaining four satellites to be launched after Space Vehicle 06 (SV06) reaches orbit, contracts have yet to be competed, although that process is likely to begin within a year or so.

 

Barring any unforeseen developments or anomalies, SpaceX’s December launch of GPS IIIA SV01 ought to kick off a series of Falcon 9 GPS missions every 4-6 months between now and 2021 or 2022. After SV08 is launched sometime in those final years, the US Air Force will open competition slightly further, allowing launch providers SpaceX, ULA, and perhaps even Blue Origin to offer multi-satellite launches on their more powerful rocket offerings, including Falcon Heavy, heavier Atlas 5 variants, and New Glenn.

Beginning in March 2019, largely symbolic but still revolutionary language to be included in 2019’s defense procurement authorization may explicitly require the USAF to explain before Congress – in the event that a launch contract does not allow a reusable rocket to compete – why an expendable launch vehicle was privileged. Currently NET March 2019 as well, SpaceX’s third dedicated USAF launch – STP-2 on Falcon Heavy – is being set up primarily to help the USAF certify SpaceX’s newest heavy-lift rocket for national security launches.

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

Published

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

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.
