SpaceX CEO Elon Musk says that the company’s first full-scale Starship prototype has completed an inaugural hop test in South Texas, igniting its lone Raptor engine and straining against a trio of tethers attached to its legs.

While relatively minor in the scope of SpaceX’s next-generation rocket program, Starhopper’s successful tethered hop now paves the way towards untethered testing in which the terminally suborbital testbed could spend several minutes aloft and reach altitudes as high as 5 km (3 mi). Aside from Starhopper itself, this perhaps marks an even more significant milestone for Raptor, completing the engine’s first successful test-fire as part of an integrated flight vehicle.

Starhopper’s first successful Raptor ignition comes after the better part of two weeks of concerted testing of the integrated prototype, beginning around March 18/19. That testing included 5+ wet dress rehearsals (WDRs) that involved loading the vehicle with a significant quantity of liquid methane and oxygen propellant, verifying the performance of avionics and plumbing, and ultimately attempting to ignite Raptor.

Ironically, less than 24 hours before Starhopper’s successful ignition, SpaceX CEO Elon Musk had noted that the rough prototype, its ground systems, or both were suffering from issues caused by ice formation in propellant valves. Reading between the lines, it’s likely that the issues involved valves on both Starhopper and its ground support equipment ‘sticking’ (i.e. failing to actuate) when commanded. While not usually a particularly large risk for the overall health of the vehicle and pad, uncooperative valves will almost invariably throw a wrench in the gears of attempted rocket operations, particularly when dealing with cryogenic propellants like those used by Starhopper.

As the supercool methane and oxygen inevitably begin to warm after leaving the propellant plant and entering Starhopper’s tanks, a fraction of the liquid will gradually transition into gas and expand, requiring constant venting of the tanks to prevent overpressure events that could damage or destroy the rocket. Falcon 9 and Heavy exhibit this same behavior, as do most other liquid-fueled rockets. This helps to explain the massive venting seen throughout Starhopper’s half-dozen or so WDR tests, as well as large but routine fireballs as excess methane gas was burned off as part of the process of vehicle and pad pressure regulation.

According to Musk, “all systems [were] green” during Starhopper’s most critical test yet. If Raptor and its prototype host are still in good health after their integrated three-second ignition test, SpaceX could attempt several more static fires and tethered hops over the next few days, mirroring the extremely rapid test series observed in February with the first completed Raptor engine.

If all proceeds nominally, it’s possible that SpaceX could begin untethered hop tests in the near future. Regardless, this marks an excellent step forward for the company’s next-generation Starship/Super Heavy spaceship and launch vehicle – all data gathered in this phase will help to optimize and improve the final design of the first orbital vehicles.

SpaceX will perform Starship double catch attempt with Flight 15

SpaceX plans to attempt what will be a defining moment in rocket reusability on Starship Flight 15.

As Elon Musk announced in a recent X post, SpaceX will attempt to catch both the Super Heavy Booster and the Starship upper stage during the upcoming orbital flight. If successful, it will mark the first time that all parts of an orbital rocket return to Earth intact, a breakthrough Musk has called essential to making life multiplanetary.

Previous flights have demonstrated the tower-catch technique with Super Heavy. SpaceX has successfully caught V1 boosters three times (on Flights 5, 7, and 8), with some even reflown. The Ship upper stage has never been caught.

Returning from orbital velocity after deploying payload makes it a significantly harder challenge due to higher energy, heat loads, and the need for precise belly-flop reentry, a flip maneuver, and a final landing burn to settle between the Mechazilla tower’s chopstick arms.

Flight 15, using Booster 22 and Ship 42 (both Block 3 vehicles), is targeted for no earlier than Friday, November 13, 2026, from Orbital Launch Pad 2 at Starbase, Texas. The 75-minute window opens at 4:45 p.m. CT, pending regulatory approval. After hot staging and separation, the booster is planned to return for a catch roughly 6 minutes and 35 seconds after liftoff.

The Ship will insert into a roughly 275 km orbit, deploy 26 advanced Starlink V3 satellites, complete about 14 orbits over more than 22 hours, and—if systems check out—perform a deorbit burn, reentry, flip, and landing burn for a tower catch at approximately T+22 hours 32 minutes.

SpaceX confirms Starship 15 launch window with massive ambitions

A simulation shown during SpaceX’s October earnings call depicted the Ship descending in a belly-flop attitude, flipping upright with a short engine burn, and being captured by the arms:

Contingency splashdown zones exist in the Gulf of Mexico (booster) and Pacific (Ship) if a catch is not viable. SpaceX has stressed rigorous health checks before committing the Ship to a return-to-launch-site trajectory.

Musk has described the odds of success on this first dual-catch attempt as “more likely than not,” noting a steady stream of additional flights is already scheduled if needed. Full recovery would enable rapid inspection, refurbishment, and reflight—slashing costs and supporting the high launch cadence required for Starlink expansion, lunar missions, and eventual Mars settlement.

As Musk put it, this is “the critical breakthrough needed to make life multiplanetary.”

SpaceX’s next Starship flight set to make history on Friday the 13th

SpaceX is targeting Friday, November 13 for Starship Flight 15 and its first ship catch.

SpaceX is targeting Friday, November 13 for Starship Flight 15, the mission the company plans to use for its first attempt at catching the ship itself with the launch tower.

SpaceX Vice President of Launch Kiko Dontchev shared the date on stage at the UP.Summit on Thursday, according to Ars Technica’s Eric Berger, who was in attendance. It is the first launch target to come directly from a SpaceX executive. Until now, the public schedule had relied on FAA air traffic planning slides, which listed Flight 15 for no earlier than November 8 and later November 12. SpaceX has not posted an official mission page yet, and no launch time has been shared.

The date lands inside the window Elon Musk sketched out last month. Speaking at Giga Texas on October 10, Musk said the flight would “probably launch a little bit before Thanksgiving,” as Teslarati reported. On SpaceX’s third quarter earnings call ten days later, he confirmed that Flight 15 would try to catch both the Super Heavy booster and the ship, and put the odds of a successful ship catch at “more likely than not.” SpaceX also aired an animation of the maneuver during that webcast, showing the ship swinging vertical over Starbase before dropping into the tower’s chopsticks.

The hardware is ready. Booster 22 fired all 33 of its Raptor engines for a full duration static fire at Pad 2 on October 25. Ship 42 followed with a single engine burn simulating a deorbit maneuver on October 26 and a 60 second firing of all six engines the next day, according to NASASpaceflight. Ship 42 had already rehearsed the catch in September, when the Pad 2 arms lifted it into position and crews connected the quick disconnect arm while the vehicle hung from the tower.

The remaining hurdle is regulatory. The FAA’s Starship page does not yet list a Flight 15 license. SpaceX President Gwynne Shotwell said in October that, after “significant constructive engagement with the FAA,” she expects the license to cover a return to the launch site and a tower catch for both stages. Bringing the ship home means a reentry path that heads toward land, rather than ending over open ocean as every Starship flight so far has.

SpaceX has caught Super Heavy three times, on Flights 5, 7 and 8, but the ship comes back from orbital velocity and has never been caught. Flight 14 on September 28 was the first Starship to reach orbit, deploying 26 Starlink V3 satellites before splashing down despite an early engine shutdown that Musk blamed on engine computer software.

Musk has called a successful ship catch “the first time that there’s been full recovery of an orbital class rocket,” and he has already named the step after it: a Flight 16 where both the booster and the ship fly again. NASASpaceflight reports that Ship 43, the next vehicle in line, is set for static fire testing in December.

Musk’s Tesla and SpaceX decline after Democratic Midterm sweep

Published

on

Tesla and SpaceX shares fell on Wednesday after Democrats swept both chambers of Congress. The decline stood out as broader market securities recovered and turned positive, while both of Musk’s publicly traded companies lagged.

CEO Elon Musk already joked about the unsuccessful campaigning for the Republicans, but now the new party will make pretty drastic changes to how it handles Tesla and SpaceX, and those companies will adjust their outlook.

Elon Musk hilariously comments on Midterm election results

Let’s take a deeper look.

Tesla ($TSLA)

Tesla shares traded lower during the regular session after Democrats secured both the House and Senate. The stock was down 2.32 percent at around 1:45 p.m. on the East Coast, trading at around $389.30.

The pressure is tied to more than the raw scale of Musk’s political spending, estimated at $450–474 million this cycle with roughly $224 million directed at Texas. In that state, Tesla now faces a Democratic governor and a Democratic senator after Gina Hinojosa unseated Greg Abbott and James Talarico defeated Ken Paxton.

The Austin Gigafactory, Robotaxi pilot programs in multiple Texas cities, and any related AI compute expansion sit under a new state executive who campaigned against certain corporate subsidies and floated a moratorium on new data-center construction.

Federally, Democratic control of key committees opens the door to deeper examination of Tesla’s autonomous-driving safety record, federal energy-storage and manufacturing incentives, and the national-security implications of any combination with SpaceX.

Investors are also weighing whether the company’s historically close alignment with the prior Republican leadership will invite slower permitting, additional hearings, or tighter rules on Full Self-Driving deployment.

For Tesla, the political shift adds near-term friction around state permitting and federal regulatory approvals for autonomy and energy storage. A potential merger with SpaceX may face slower review even if it proceeds.

Core growth drivers such as vehicle deliveries, energy deployments, and robotaxi rollout remain intact, yet the stock now carries a higher political-risk premium that could weigh on valuation until the company demonstrates workable relationships with the new Texas leadership and congressional majorities.

SpaceX ($SPCX)

SpaceX shares also declined in live trading on November 4 following the Democratic midterm sweep. The stock traded at $134.97, down 4.49 percent. The drop occurred even as broader indexes stabilized, highlighting a company-specific reaction to the election outcome.

Musk’s large contributions, concentrated in Texas races that both companies lost, place SpaceX’s Starbase launch facility and headquarters under a new Democratic governor.

At the federal level, Democratic control of Congress enables greater scrutiny of NASA, the Department of Defense, and other contracts that support a meaningful share of revenue, along with reviews of Starlink national-security uses and any Tesla merger. Analysts have noted that empowered committees can hold hearings and request documents on these relationships.

For SpaceX, the results raise the risk of delayed contract awards, higher compliance costs, and tighter constraints on AI and satellite infrastructure expansion, particularly in Texas where a data-center moratorium has been discussed.

A merger with Tesla could encounter political friction that slows integration of launch, connectivity, and autonomy capabilities.

While Starlink growth and launch cadence continue as primary drivers, the company faces a more contested path for federal funding and state-level operations, requiring management to rebuild ties with the new congressional majorities and Texas leadership to limit the overhang.
