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 has trimmed its Model Y offerings as its Standard All-Wheel-Drive configuration has been removed from the online configurator after roughly nine months on sale. The move follows the removal of the Cybertruck, as its trims have also been minimized as that vehicle heads for total discontinuation at the end of Summer 2027.
Launched in February 2026 as a mid-tier dual-motor option between the Rear-Wheel-Drive model and the Premium trims, the Standard All-Wheel-Drive Model Y offered 294 miles of range and a 4.6-second 0-60 mph time in a stripped-down package.
🚨 Tesla has pulled the $41,990 Model Y AWD from its U.S. configurator after nine months on sale.
The cheapest AWD Model Y you can order is now the $49,990 Premium AWD, with Premium deliveries quoted for Jan–Mar 2027.

With it gone, the cheapest new AWD Model Y buyers can configure is now the Premium AWD at $49,990, with estimated deliveries pushed into January–March 2027. The $39,990 rear-wheel-drive Model Y remains available for custom orders, and some AWD units are still listed in inventory.
The move arrives days after Tesla sharply narrowed its Cybertruck lineup. New orders for the Dual Motor AWD and Premium AWD versions have been disabled, leaving only the high-performance Cyberbeast—priced around $109,990 before fees—as the sole configurable option.
Elon Musk has stated that Cybertruck production at Gigafactory Texas will wind down around the middle to late summer of 2027 to free manufacturing space for greater Cybercab output. Tesla has raised prices on remaining trims and is prioritizing higher-margin builds while working through an existing order backlog that exceeds what the line can complete before conversion.
These parallel decisions reflect a broader effort to simplify Tesla’s retail customer lineup. Lower-volume or lower-margin variants are being phased out or deprioritized in favor of core, higher-spec models that generate stronger profitability and clearer production planning.
For the Model Y, this concentrates volume on the remaining RWD and Premium configurations while Premium deliveries already stretch into 2027. For the Cybertruck, it accelerates the transition away from a stainless-steel pickup that underperformed relative to initial volume expectations.
Tesla Model Y Standard Full Review: Is it worth the lower price?
The freed capacity and reduced complexity directly support Cybercab scaling. Tesla began pilot Cybercab production at Giga Texas in early 2026, launched paid autonomous rides in Austin in September, and is preparing for substantial volume growth.
By streamlining the existing vehicle portfolio, the company is reallocating factory space, engineering attention, and supply-chain resources toward its purpose-built Robotaxi, which lacks a steering wheel or pedals and is designed exclusively for unsupervised autonomy.
The result is a leaner retail lineup today and a clearer path to high-volume Cybercab deployment tomorrow.

SpaceX Starship is going for a catch that could change spaceflight forever
SpaceX will try to catch both Starship stages today, a first for any orbital rocket.
SpaceX is set to launch Starship Flight 15 from Starbase on Friday afternoon, and if both stages make it back to the tower, the mission will go down as the first time an orbital rocket has ever been fully recovered. The 75 minute launch window opens at 4:45 p.m. CT from Pad 2, a day after SpaceX rolled Ship 42 out to the pad and shared photos of the move on X.
The first catch comes quickly. About six and a half minutes after liftoff, Booster 22 is scheduled to fly back to Starbase and settle into the launch tower’s chopstick arms, the first catch attempt for SpaceX’s V3 Super Heavy. SpaceX has caught the booster three times before most recently in March 2025.

The second catch is the one that has never been done. Ship 42 will climb to an orbit about 275 kilometers up, deploy 26 Starlink V3 satellites and complete about 14 orbits. Three of those satellites carry cameras to inspect the ship’s heat shield before it commits to coming home. If its reentry, landing burn and tower approach systems pass their checks, the ship will fire its engines to leave orbit, fall through the atmosphere in its belly flop position, flip vertical and drop into the tower about 22 and a half hours after launch, on Saturday afternoon. SpaceX gave a preview of that maneuver in an animation during its third quarter earnings webcast.
Elon Musk described a successful double catch on that call as “the first time that an orbital launch vehicle has been fully recovered” and a “profound technology milestone,” putting the odds of catching the ship at “more likely than not.” SpaceX has called it a potential “breakthrough moment in making Starship a reliable, rapidly reusable rocket,”
Reuse is where the economics change. Falcon 9 lands its boosters routinely, but its upper stage is thrown away on every flight. Starship is designed so both stages can be refueled and flown again, which is key to cutting launch costs. That matters for Starlink, where each V3 satellite is expected to carry roughly 10 times the download capacity of the V2 Mini satellites flying today, and for Starmind, SpaceX’s planned constellation of AI compute satellites.
It matters for NASA too. Starship is the lunar lander for the Artemis program, and reaching the Moon requires refilling a ship in orbit using several tanker flights. That plan only works if Starships can fly again and again. Musk has said he expects Starship to reach a weekly launch cadence in the first half of 2027.
Investors are paying attention. Morgan Stanley’s Adam Jonas wrote this week that a catch of both stages would likely be “a material positive” for SpaceX stock.
The last Starship flight in September reached orbit for the first time but ended after about three hours with a splashdown in the Pacific, short of its planned 10 hours, after some engines shut down. Since then, Booster 22 has completed a full 33 engine static fire and Ship 42 a six engine firing, as Teslarati previously reported. As of Friday morning, SpaceX was still waiting on the FAA to approve a license change covering the ship’s return over land.

Tesla and SpaceX merger talks hit a new stage, and one hurdle remains
Tesla and SpaceX merger talks are reportedly advancing, and a deal could arrive by December.
Tesla and SpaceX are moving closer to a combination, with a deal announcement possible as soon as December, Bloomberg reported on Thursday, citing people familiar with the matter. The companies have also discussed a scenario in which the announcement slips into early 2027.
Boards and advisers on both sides are now working through the terms of the deal and the governance structure of the combined company, according to the report. One open item is how many SpaceX shares Tesla investors would receive. Bloomberg had previously reported that the two companies were aiming to announce a deal in the first half of next year and close it before the end of President Donald Trump’s term, so a December announcement would pull that schedule forward by months.
Tesla shares rose as much as 1.9% to $398.35 after the report, while SpaceX gained 0.6% to $140.63. SpaceX carries a market value of about $1.9 trillion following its June IPO, and Tesla is valued at about $1.55 trillion, which would make a combination the largest corporate deal on record. Neither company responded to requests for comment.
The talks became official on October 20, when Elon Musk said on SpaceX’s third quarter earnings call that both companies had formed special committees of independent directors to study a merger, as Teslarati reported. Musk said he could not take part because he is “a conflicted party” and called the process “an odd kabuki dance.” He also noted that Tesla would need approval from 50 percent of all outstanding shares, a bar the company missed in 2025 when a board declassification proposal won support from only 39.4 percent.
China remains the biggest structural problem. Bloomberg’s sources said the companies still need to work out how to isolate Tesla’s large and profitable manufacturing business in China from SpaceX’s U.S. government and defense contracts. JPMorgan analyst Rajat Gupta described those two factors last month as “key dynamics that are at odds with each other” for regulatory and shareholder approval. Musk has repeatedly said Tesla has no plans to separate its China business, a position he restated in August after ARK Invest predicted a merger announcement before the end of the year.
Washington adds another layer. Democrats took control of Congress in this month’s midterms and have pledged to investigate Musk’s business and political activities, which could bring added scrutiny to a deal involving one of the Pentagon’s most important launch and satellite contractors.
The report also lands three weeks before Tesla’s December 3 annual meeting at Giga Texas. That ballot has only three items, led by the re-election of Musk, board chair Robyn Denholm and JB Straubel, and includes no merger proposal. Any deal announced in December would likely require a separate special meeting for Tesla shareholders to vote on it.
The two companies already share a growing list of projects, including the Terafab semiconductor plant in Texas. Tesla’s next generation Roadster, which uses cold gas thrusters built on SpaceX hardware, turned up on display at SpaceX headquarters last month and has become one of the clearest public examples of that overlap.
