The massive United Launch Alliance (ULA) Delta IV Heavy rocket last launched from Space Launch Complex 37 (SLC-37) at Cape Canaveral Air Force Station in August of 2018 when it lifted NASA’s Parker Solar Probe to a highly-elliptical, heliocentric orbit on a mission to “touch the Sun.”

Two years later, ULA is ready to light its most impressive candle once again for its next launch campaign, NROL-44. This time around the protective payload fairing of the Delta IV Heavy rocket is packed with a sensitive – and highly classified – payload for the National Reconnaissance Office (NRO). The NRO is an office of national security that oversees a fleet of spy satellites for the United States government. Since becoming operational in 2004, ULA’s Delta IV Heavy rocket has completed eleven operational missions, seven of which were classified missions for the NRO.

A long launch campaign

The NROL-44 launch campaign has been a long one, to say the least. The three Delta IV common core boosters were delivered to ULA’s Horizontal Integration Facility during the summer of 2019. There the boosters were integrated with one another while the forward end of the center booster was mated with the Delta Cryogenic Second Stage (DCSS). The DCSS is outfitted with a single Aerojet Rocketdyne RL10B-2 engine capable of 24,750 lbf of thrust used to propel the secretive payload to orbit once the common core boosters have separated.

In November 2019, the rocket was rolled to the SLC-37 Vertical Integration Facility and raised by ULA’s Fixed Pad Erector into a vertical position to await the integration of its precious payload. In January 2020, ULA completed pre-launch initiatives including standard testing and a complete Wet Dress Rehearsal of Day of Launch activities involving fueling and de-tanking of the liquid hydrogen and liquid oxygen propellants. Since then, the Delta IV Heavy has remained safed and in powered-off status.

Following the recent successful launch of NASA’s Perseverance Mars rover on a neighboring ULA Atlas V just weeks ago, ULA is ready to ignite Delta IV Heavy’s three Aerojet Rocketdyne RS-68A main engines to complete one of the rocket’s remaining final five flights as it nears retirement.

On July 27, the Delta IV Heavy was outfitted with a 5-meter payload fairing safely encapsulating the NROL-44 payload. The massive payload fairing was delivered to SLC-37, raised, and mounted to the top of the center booster and fully integrated DCSS via crane. The mated payload completes the 235 feet (72 meters) tall full stack of the Delta IV Heavy rocket which will weigh in at 1.6 million pounds (725,750 kg) once fueled before lift-off.

Reliability worth the cost

In a company blog post, ULA’s launch operations director and general manager, Tony Taliancich said, “The Heavy serves the nation’s high-priority U.S. Space Force and National Reconnaissance Office space programs with distinction as America’s proven heavy-lifter.” Although reliable, the Delta IV Heavy is very costly to fly costing nearly $300 million a launch. The heavy class launcher is almost exclusively chosen to fly missions for the U.S. government with the exception of a few NASA missions – Parker Solar Probe and the Orion capsule Exploration Flight Test -1. The five remaining flights of its career are all contracted to lift payloads for the NRO through 2023.

ULA is currently targeting 2:16 am EDT (0616 UTC) on Wednesday, August 26 for the launch of the Delta IV Heavy, however, tropical weather approaching the Florida peninsula is being closely monitored. Should there be any, ULA will publish all updates to the mission timeline on the company’s blog.

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

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.
