United Launch Alliance successfully test fires new Vulcan rocket
United Launch Alliance successfully test-fires new Vulcan rocket
Following a successful Flight Tanking Test (FTT), United Launch Alliance fired up the Vulcan rocket for the first time last night. The two Blue Origin-built BE-4 rocket engines ignited for 6 seconds and pushed ULA closer to their maiden launch of the rocket.
United Launch Alliance stated they are more than 98 percent through the qualification program for Vulcan, and after reviewing data from the Flight Readiness Firing (FRF) and closing the Centaur V anomaly investigation, they will then announce launch plans.

During this test firing, the BE-4 engines ignited at T- 4.88 seconds and ramped up to 60% power for 2 seconds before powering down.
The United Launch Alliance Vulcan Centaur rocket has faced many delays leading up to this moment, most recently experiencing an anomaly of the Centaur V upper stage that was undergoing qualification testing at the Marshall Space Flight Center in Alabama.
ULA is currently conducting an investigation into the cause of the anomaly, and according to ULA CEO Tory Bruno, they found the issue was on the Centaur upper stage itself, but they are still determining if changes will need to be made to its current flight article that is stacked on Vulcan.

Prior to this unexpected issue, Blue Origin originally had planned to deliver two of their flight-ready BE-4 engines to ULA for integration onto the Vulcan rocket by 2020, but various delays in qualifications and testing meant their delivery slipped significantly to late 2022.
Following their integration onto the Vulcan rocket’s first stage, it was then shipped aboard ULA’s ‘RocketShip’ down the Mississippi River, through the Gulf of Mexico, and after rounding the southern tip of Florida to Port Canaveral, Florida, after which it was unloaded and then transported to the Vertical Integration Facility at Cape Canaveral Space Force Station.

This FRF test comes before the planned Summer launch of Vulcan Centaur carrying Astrobotics Peregrine Lunar lander and Amazon’s first two Kuiper satellites, their answer to the SpaceX Starlink satellite constellation.
Also known as the CERT-1 flight, the Vulcan Centaur rocket needs to perform 2 successful launches to qualify to launch national security payloads for the U.S. Space Force and other government payloads.
The second flight will feature the first launch of the Sierra Space Dream Chaser space plane, which will deliver supplies to the International Space Station. As of now, the majority of the payload manifest for Vulcan Centaur is Amazon’s Kuiper satellite constellation and U.S. Space Force national security missions.
The Vulcan Centaur rocket has a few configurations available to suit multiple payload sizes, the rocket can fly with just the 2 BE-4 engines delivering 1.1 million pounds of thrust at sea level to flying with 2, 4, or 6 solid rocket boosters and with 6 SRB’s it would bring its thrust up to 3.8 million pounds.
This would make the Vulcan Centaur capable of delivering 60,000 lbs (27,200 kg) to low Earth orbit or 25,400 lbs (11,500 kg) to the Moon. ULA is also working toward its SMART re-use system, which will allow the 2 BE-4 engines to separate from the first stage, and after an inflatable heatshield deploys, they would return to Earth and splash down for recovery and refurb for their next mission.
However, it is unknown when ULA will begin using this capability.

SpaceX’s biggest test yet arrives this week and it’s not a rocket launch
SpaceX will report second quarter results after the market closes on Tuesday, August 4, marking the first time the company has opened its books to the public since its record IPO in June. Management will host a live audio only webcast at 4:30 p.m. ET, streamed on X, with no dial in option.
The debut carries more weight than a typical first quarter as a public company. Two trading days after the release, on August 6, the first tranche of SpaceX’s lockup expires, freeing roughly 911.5 million insider and employee shares, worth well over $100 billion at current prices and the largest such release in Wall Street history. A second, larger tranche tied to the stock trading 30 percent above its $135 IPO price never triggered, since shares have spent most of July trading below that price.
Wall Street’s models point to revenue near $6.9 billion for the quarter, up sharply from the $4.69 billion SpaceX reported in the first quarter, with a narrower per share loss than the $1.27 posted three months earlier, according to estimates compiled by Motley Fool. Those numbers will be the first look at how SpaceX’s three segments, Starlink, launch and AI, are performing independently.
SpaceX scores another massive Pentagon deal to support military satellites
Investors heading into the call have a specific list of questions. How many net new Starlink subscribers did SpaceX add after ending March with 10.3 million, and is average revenue per user holding up as the service expands into lower income markets. How much of the AI segment’s revenue reflects contract signings with Anthropic, Google and Reflection AI this year, deals that combined could annualize to nearly $28 billion if fully ramped. Whether capital expenditures, which nearly doubled in the AI segment alone between 2024 and 2025, are still accelerating or starting to plateau. And whether management offers any forward guidance at all, something SpaceX has never done publicly.
The report will also land days after Elon Musk publicly denied a Wall Street Journal report describing internal planning to separate Tesla’s China business ahead of a potential Tesla-SpaceX merger. Whether Musk or SpaceX executives address that speculation on the call, even indirectly, maybe something investors will be listening for on Tuesday.
As Teslarati reported after Musk’s own warning to short sellers last week, the CEO has made clear he expects skeptics to be proven wrong over time. Tuesday will be the first chance for the numbers themselves to make that case.

SpaceX’s Starship just got filmed by its own cargo
SpaceX released new footage of Starship in space captured by the Starlink satellites it deployed.
SpaceX released a new video Friday evening showing Starship from an angle showcased by its own Starlink satellites, watching the rocket drift away in orbit.
The 65 second clip, posted on X, stitches together footage from four cameras mounted on a single Starlink V3 satellite. It opens with a close view of Starship’s 171 foot upper stage, still catching sunlight, then pulls back as the two spacecraft separate.
The footage comes from Starship’s 13th flight test, which launched July 24 from Starbase after a scrubbed attempt and an abort caused by an engine issue the week before. When Flight 13 finally flew, it carried the first batch of functional Starlink V3 satellites Starship has ever deployed, twenty of them, with six equipped with cameras meant to scan the ship’s heat shield during reentry.

Flight 13 checked most of its boxes. Starship deployed all 20 satellites, relit a Raptor engine in space, and splashed down softly in the Indian Ocean off Western Australia. Musk’s longer term plan calls for a Starlink V3 constellation of 100,000 satellites, according to a recent FCC filing, with Starship as the only vehicle capable of launching them at the volume that requires. Each Starship flight is designed to carry up to 60 V3 satellites once the vehicle reaches routine service, well beyond what Falcon 9 can carry in a single mission.
Starship is next expected to fly with an attempt at catching the ship itself with the launch tower’s mechanical arms, a maneuver SpaceX has so far reserved for the Super Heavy booster.

Tesla Model Y L’s new features flexed at unveiling event at Diner
Tesla flexed the new features of the Model Y L with a dedicated media event at the company’s Diner on Santa Monica Boulevard in Los Angeles.
The Model Y L is the extended-wheelbase version of the all-electric crossover, which has been voted the best-selling car in the world on three occasions. The vehicle is already rolling off production lines at Gigafactory Texas, and first deliveries are slated to take place later this year.
Tesla brings Model Y L ‘Launch Series’ to the U.S. at $61,990
Teslarati was invited to the event, but due to some scheduling conflicts, we could not make it to Los Angeles. Instead, we will have our hands on a media unit sometime in August, so we’ll be able to spend some more extended time with the Model Y L.
However, plenty of those who made it to LA shared some cool features that set the Model Y L apart from the Model Y.
Multi-Row Climate Control
Tesla fitted the Model Y L with full climate control on all three rows on the front screen. It can be adjusted by selecting which row you’d like to modify on the right-hand side of the touch screen:

Better Rear Window Visibility
One of the strangest things about the Model Y, especially the Juniper iteration, is the rear window has extremely limited visibility when looking into the rearview mirror.
Tesla has improved upon this with the Model Y L:
This is a drastic difference. https://t.co/wTdhitD5aA pic.twitter.com/z6hFs0Jkss

PowerShare will be included
Model Y L will come with PowerShare in North America, with an 11.5kW output to your home. Tesla said it would require Powerwall 3 for operation.
Wireless Charging Pad
There has been some speculation that Tesla would upgrade the wireless charging pads in the United States, but this is not the case.
Tesla owner fixes common feature complaint with crafty DIY retrofit
Tesla confirmed that it does not come with the cooled pads as the Y L in China does. This is because North America has not adopted Qi charging yet.
Thermal Management Improvements
These improvements in the Model Y L were seen with thermal management:
- Up to 15% faster cabin cooling
- +23% thermal efficiency gained in hot weather, 7 miles of real-world range gained
- 8x more solar energy reflection off of glass roof
- 30% reduction in solar energy entering the cabin
Some of the thermal management improvements in the new Model Y L Premium:
• Up to 15% faster cabin cooling
• Up to 15 min faster cabin cooling in sunny conditions
• +23% thermal efficiency gained in hot weather +7 miles of real-world range gained
• +10 miles recovered after… pic.twitter.com/jZirFWFdtO— Sawyer Merritt (@SawyerMerritt) July 31, 2026
Demand
Tesla said the Model Y L is almost sold out in the U.S. It comes with
- 1 year of FSD Supervised
- 1 year of Supercharging
- 1 year of Premium Connectivity
- Free exterior paint color, interior, and wheel option at no additional cost
