SpaceX delays Starhopper’s first flight a few days despite Raptor preburner test success
SpaceX has (partially) ignited Starhopper’s freshly-installed Raptor engine, successfully verifying that the engine is ready for its next major test: a full ignition and static firing. Although successful, SpaceX still has some work to do before the vehicle is ready for its first untethered flight(s).
July 15th’s progress is just the latest in a several day-series of preflight tests designed to reduce the likelihood that Starhopper is destroyed over the coming days and (hopefully) weeks. If all goes planned during the awkward Starship prototype’s first foray into hover tests, SpaceX CEO Elon Musk has stated that he will provide an official presentation updating the public on the status of the company’s ever-changing next-generation rocket.
The past week or so of Starhopper preflight testing began with Raptor serial number 6 (SN06) completing the last of a series of acceptance test fires in McGregor, Texas on June 10th. Even on its own, this was a major milestone for the new SpaceX engine: Raptor SN06 was the first of the new, full-scale engines to pass the acceptance test program with flying colors. According to Musk, for the engine to complete those tests so successfully, SpaceX had to solve a challenging bug in which some sort of mechanical resonance (i.e. vibration) damaged or destroyed Raptors SN01-05.
Hours later, the engine began a short ~450 mi (720 km) journey south to Starhopper, located in Boca Chica, Texas. The engine arrived on July 11th and was fully installed on Starhopper by the following evening (July 12th), at which point SpaceX put Starhopper and Raptor through some mild but valuable thrust vector controller (TVC) tests, wiggling the car-sized engine to ensure it can accurately steer the prototype rocket.
Around two days after the above ‘wiggle’ test was successfully completed, SpaceX moved into the next stage, partially fueling Starhopper with liquid methane and oxygen propellant and helium pressurant in what is known in rocketry as a wet dress rehearsal (WDR). The (implicitly) successful WDR was capped off with a duo of what can now safely be concluded were some sort of Raptor test preceding even pre-ignition operations. Whatever the tests were, they appear to have been completed successfully.
That appears to be the case because less than 24 hours after their completion, on July 15th, SpaceX once again began loading Starhopper with propellant and pressurant for a second round of wet testing. This time around, SpaceX got right into more critical Raptor tests once enough propellant was loaded, igniting the engine’s interwoven oxygen and methane preburners.
Previously discussed 24 hours ago in a Teslarati article focused on Raptor wiggles and other miscellaneous tests, Raptor is an extremely advanced rocket engine based on a cycle (i.e. how propellant is turned into thrust) known as full-flow staged combustion.
“In a staged-combustion engine like Raptor, getting from the supercool liquid oxygen and methane propellant to 200+ tons of thrust is quite literally staged, meaning that the ignition doesn’t happen all at once. Rather, the preburners – essentially their own, unique combustion chambers – ignite an oxygen- or methane-rich mixture, the burning of which produces the gas and pressure that powers the turbines that bring fuel into the main combustion chamber. That fuel then ignites, producing thrust as they exit the engine’s bell-shaped nozzle.
Unintuitively, conditions inside the preburner – hidden away from view – are actually far more intense than the iconic blue, purple, and pink flame that visibly exists Raptor’s nozzle. Much like hot water will cool while traveling through pipes, the superheated gaseous propellant that Raptor ignites to produce thrust will also cool (and thus lose pressure) as it travels from Raptor’s preburner to its main combustion chamber. If the pressure produced in the preburners is too low, Raptor’s thrust will be (roughly speaking) proportionally limited at best. At worst, low pressure in the preburners can trigger a “hard start” or shutdown that could destroy the engine. According to Elon Musk, Raptor’s oxygen preburner thus has the worst of it, operating at pressures as high or higher than 800 bar (11,600 psi, 80 megapascals).”
In full-flow staged combustion (FFSC), even more complexity is added as all propellant that touches the engine must necessarily end up traveling through the main combustion chamber to eke every last ounce of thrust out of the finite propellant a rocket lifts off with. As such, FFSC engines can be about as efficient as the laws of physics allow any given chemical rocket engine to be, at the cost of exceptional complexity and brutally difficult development.
Additionally, FFSC physically requires two separate preburners and then makes things even harder by making each separate preburner (methane and oxygen) depend on each other’s operation for the engine to fully ignite. This means that no individual preburner can be used to kickstart Raptor – instead, SpaceX must somehow spin the turbopumps that feed propellant into each preburner with some separate system. This is all just to emphasize the fact that Raptor’s ignition sequence is a spectacularly complex orchestra of valves, spark plugs, sensors, and magic. This is why it’s valuable for Raptor to test its preburner system independently of an actual ignition test, at least as long as the engine is still in the development stages.
According to NASASpaceflight.com managing editor Chris Bergin, what this practically translates to is a minor Starhopper hover test delay of 1-2 days, while the static fire has also been pushed roughly 24 hours from July 15th to July 16th. If that full static fire produces lots of happy data, Starhopper could be cleared for a hover test debut attempt as early as Wednesday or Thursday (July 17/18).

Tesla Cybertruck’s three configurations are all the same on the outside from an appearance perspective, but they differ slightly in price, range, performance, and other features. After yesterday’s price adjustment, Tesla’s Base All-Wheel-Drive Cybertruck is now priced at $74,990, a far cry from the $59,990 it started at several months ago.
At $60,000, the Cybertruck All-Wheel-Drive is a steal: no pickup, electric or gas-powered, comes close in terms of overall driving capability thanks to Steer-by-Wire; no truck is more fun to drive at that price, and add in Full Self-Driving for $99 per month, and you truly have the best possible pickup on the market, at least if you’re planning to use it for driving.
I unfortunately didn’t have the equipment to test towing and payload and how it impacts the truck.
But at $75,000, is it still worth it? Obviously, the question gets to be more difficult because of the $15,000 difference. But there’s still an argument.
I spent the last week with this awesome truck, and when I took it back, I was sad because it truly is the best Tesla in the lineup. I formerly said the Model S was my favorite Tesla, but after a week with Cybertruck, I can easily say it would be my choice over the now-defunct all-electric sedan.
What makes it so great? Well, a lot of things, and there are some things that I’d like to see change. However, this is a truck that truly has a serious argument for those who are thinking of trying something completely different.
Exterior and Interior
This build comes with 18″ Molten Wheels as the standard offering, but 20″ Core Wheels with 35″ tires are also available. The standard wheel option on this affordable model is not my favorite, but it can be easily swapped for something more attractive.
Overall, this particular build did have some panel gap issues that were especially noticeable between the hood and both front quarter panels. This is obviously not an “across the board” issue, as the Cyberbeast I took home for comparative reasons was significantly better overall.

The interior is different, with its textile material instead of the vegan leather. Personally, I missed the leather due to the ventilated seats, but I prefer the textile as I personally felt like they were more comfortable. This is something I’d definitely consider if I were between the three trim levels and money was not really an issue.
After 610 miles on Monday in this thing, I did not feel any different than I did when I left my house that morning. It feels like a living room on wheels; after a long drive, you truly do not feel as if you’ve been in a car all day long.
My biggest interior complaints were that I’d like at least two USB-C ports in the front; you are confined to just one, and it’s hidden in the center console. The rear row has two ports. Additionally, the windshield is super difficult to clean, so if you end up buying one of these, save your back and get something that extends.
Driving Performance and Comfort
One of the most surprising things about Cybertruck is the fact that it is perhaps the smoothest ride of any Tesla available. Most believe it might be rough, stiff, and rugged like most trucks, maybe not as forgiving on the back and bottom as you sit in it for an extended period of time.
I’m here to tell you, you won’t regret sitting in a Cybertruck for a long drive.
I put as many people who dislike EVs, don’t like Cybertrucks, or use trucks for work, and judge the Cybertruck in this thing in the past week. Every single person who got in this truck loved it: they loved the speed, the handling, FSD, the space, the capability, and the feel.
As previously noted, even after hundreds of miles and 14 hours spent driving around Pennsylvania, I didn’t feel tired, exhausted, or in any hurry to come home. I would have driven another 300 miles without question.
Final Thoughts
If I had my choice of the three Cybertruck trims, I think I’d take the All-Wheel-Drive for a few reasons. Initially, the price is more attractive, it is not that stripped of features, and it has everything I need.
Is it worth it at $75,000? I believe it is. I’ve driven trucks that are at a higher price point and consider this to be a better product from a driving and experience perspective. However, other pickups on the market have more towing capacity, payload capacity, and range. They do not have FSD or steer-by-wire, the two things that truly make the Cybertruck in a league of its own.
I can’t think of a time in recent memory that I’ve been this excited to drive a vehicle each day, and I literally look for excuses to drive my Model Y on a daily basis. This Cybertruck just blows the Model Y out of the water in every possible way, at least in my opinion. With the size, performance, and driving experience, there is no better Tesla out there.

County vote hands Elon Musk’s Vegas tunnel network a huge new target
Clark County approved 19 more Vegas Loop stations, pushing Boring Company’s entitled total to 123.
The Boring Company just got permission to nearly double how far Vegas Loop can reach. Clark County commissioners approved 19 additional stations for the underground transit system, bringing the total entitled to 123, the company said in a post on X thanking the county for the vote. Elon Musk’s tunneling company also flagged the direction it sees the project heading long term. “Because Loop is point-to-point with no intermediate stops, in the limit, one could have a Loop station in every driveway,” the company wrote.
That framing captures how far the ambitions have moved. The Vegas Loop opened its first stretch of tunnel in 2021 and has grown its footprint through a string of county approvals since. In 2023, commissioners signed off on 18 additional stations, part of a plan that later doubled the system’s target to 69 stations across 65 miles. By the end of that year the company was describing a build out closer to 93 planned stations. Last year the long term design called for 104 stations across 68 miles of tunnel. The new approval pushes that number to 123, another jump in a project that keeps outgrowing its own blueprints.
The Boring Company gets approval for more stations in Las Vegas
Station count on paper is still well ahead of what riders can actually use. As Teslarati reported earlier this month, the network has about 11 open stations and has carried more than 4 million passengers since it began running, with newer stops at Fontainebleau and Sahara among the latest additions to the Strip corridor. A tunnel connection to Harry Reid International Airport remains under construction and has already slipped past its original first quarter target. The company is also racing to finish a Westgate to Paradise Road segment that Las Vegas Convention and Visitors Authority CEO Steve Hill has said it hopes to have running in time for November’s Formula 1 race.
The gap between entitled stations and operating ones is where the real story sits. Regulatory approval gives Boring Company the legal runway to keep tunneling toward new resorts, residential pockets and eventually the airport, but building each connection still comes down to boring machines, fire safety sign offs and construction timelines that have slipped before. The company’s Prufrock series machines set an internal record in March with a 2.28 mile tunnel near Westgate, evidence that construction has been picking up even as the list of approved destinations grows faster than the tunnels themselves.
Musk’s driveway comment reads as aspirational rather than a near term plan, but it fits how Boring Company has talked about Vegas Loop from the start: treat every approval as a floor, not a ceiling, and keep pushing county officials for room to dig.
SpaceX announced today that it would expand its launch capabilities into a new U.S. state: Louisiana.
Today, SpaceX, in conjunction with the Louisiana Economic Development Office, said that it will establish a new launch facility, which it will call Starbase, Louisiana. It will be located near Vermilion Parish, supporting thousands of launches each year, at least eventually.
CEO Elon Musk commented by stating, “Starbase Louisiana will ultimately have over a dozen launch towers, enabling more than 30 Starship flights per day and making it the biggest launch site on Earth!”

The expansion is SpaceX’s latest move to push its launch cadence to be more frequent than ever. SpaceX said that Starbase, Louisiana, will be built to “support thousands of Starship flights a year,” with the first coming in 2029.
SpaceX announced the new facility in partnership with the Louisiana Economic Development Office as it will bring a major influx of jobs and investments into the area. Currently, it will produce more than 3,000 new jobs in Louisiana, and SpaceX plans to invest at least $100 billion into the entire facility, ensuring that many jobs are created as a result.
Environmental Responsibility
SpaceX acknowledges the impact launches could have on marshlands, local wildlife, and water sources. Here’s how the company plans to help with the issues in Vermilion Parish:
- Restoring the Shoreline: “In Vermilion Parish, the shoreline is eroding between 3.3 and 23 feet per year. We’re partnering with state and federal agencies to expand Louisiana’s Coastal Master Plan and Coastal Wetlands Planning, Protection and Restoration Act projects, including Gulf shoreline protection breakwaters designed to reduce wave energy and slow loss along the Gulf edge.”
- Rebuilding the Marshlands: “In working with the state, we’re planning thousands of acres of marsh creation using beneficial-use placement of dredged material and offshore sediment sources. Restoration will also include interior marsh bank stabilization and rebuilding marsh in remnant canals. These projects can reconnect fragmented wetlands, restore natural buffers against storms, and return habitat that has been lost to erosion and historic canalization.”
- Preserving Coastal Wildlife: “Pecan Island and nearby wetlands are high-value habitat for migratory waterfowl, shorebirds, wading birds, and other coastal wildlife. SpaceX is not developing the full footprint of the land and will preserve wetlands and wildlife habitat. At existing launch sites, waterfowl and other birds continue to use nearby habitat during operations. Working with wildlife agencies, landowners, and conservation groups, SpaceX will support monitoring and management so this habitat stays productive and hunting, fishing, birding, and other recreational activities that are part of this coast’s culture can continue.”
SpaceX shares rose about 2.5 percent on the news.
