Speaking on Friday, March 8th, SpaceX CEO Elon Musk announced that the company’s second completed Raptor engine was already “on [its] way to [Star]hopper” to – nominally – be installed on the prototype vehicle as early as the week of March 11th (this week).

According to an official SpaceX statement, once Raptor is installed on Starhopper, the integrated vehicle will perform a combination of ground systems testing, propellant loading, static fire tests, and low-altitude hover demonstrations to prove out the brand new vehicle, engine, and facilities. Prior to the final months of 2018, the build site, launch pad, and prototype Starship now preparing for imminent hop tests were little more than empty dirt lots on the southern tip of the Texas coast.

“SpaceX will conduct checkouts of the newly installed ground systems and perform a short static fire test in the days ahead,” he said. “Although the prototype is designed to perform sub-orbital flights, or hops, powered by the SpaceX Raptor engine, the vehicle will be tethered during initial testing and hops will not be visible from offsite. SpaceX will establish a safety zone perimeter in coordination with local enforcement and signage will be in place to alert the community prior to the testing.” – James Gleeson, March 8th, SpaceX

Prior to February 3rd, barely one month ago, SpaceX’s next-generation Raptor engine had yet to even ignite in its final(ish), full-scale form. Less than two weeks after that, SpaceX’s propulsion team had pushed the engine to the point of damage, quite possibly throttling it above its nominal max thrust and main combustion chamber pressures. According to Musk, Raptor serial number 2 (SN02) will feature moderate changes to mitigate the cause of that damage.

Along the path to hop tests, it’s unclear if Raptor SN02 – following the mild problems more or less intentionally forced upon its predecessor – will be test-fired at SpaceX’s McGregor, Texas development facilities before heading south to be installed on Starhopper. Given SpaceX’s methodical approach to engine and vehicle testing prior to the launch of any of its rockets, chances are good that it will have already conducted a number of basic acceptance tests in McGregor. If Musk is to be taken literally, the second flightworthy engine may already be in Boca Chica, although it’s more likely that it’s simply close to shipping there from either Hawthorne or McGregor.

It has not yet been confirmed if Starhopper will initially perform static fire and hop tests with just one Raptor installed, but the sheer power of the fairly compact engine (upwards of 200 metric tons or 450,000 lbf of thrust at full throttle) should more than enable an extremely heavy prototype to lift off even with 50+ metric tons of propellant onboard. While it could simply be a matter of convenience and efficiency to start integrated Starhopper testing immediately instead of waiting for the completion of additional Raptor engines, the process of testing a thrust structure or integrated rocket with an increasing number of engines installed is a relatively common practice in aerospace. Regardless of its history, SpaceX itself also began its first integrated testing of a Falcon 9 first stage in the same way, starting with one Merlin engine installed and ultimately graduating to 3, 5, and the final 9 engines over the course of a few months of testing.

While Starhopper is unlikely to need more than a handful of Raptor engines to exhaust its usefulness, the first orbital Starship prototype – and, even more so, the first Super Heavy booster – will almost certainly end up going through the same process of methodical hot-fire testing before SpaceX even thinks of attempting the first orbital BFR launch. Featuring 7 and 31 Raptors respectively, Starship and Super Heavy will radically push the envelope of both SpaceX’s own experience and the aerospace industry as a whole, potentially becoming the most powerful liquid rocket ever launched if or when the vehicle begins flight tests with both stages.

SpaceX just got the green light Starship has waited years for

The FAA has cleared Starship Flight 14, setting up SpaceX’s first orbital attempt on Monday.

SpaceX has cleared the last regulatory hurdle standing between Starship and its first trip to orbit. The Federal Aviation Administration issued the launch license for Starship Flight 14 late Saturday, keeping the mission on track for liftoff Monday, September 28, from Pad 2 at Starbase, Texas.

The 75 minute launch window opens at 7:15 a.m. Central, and Boca Chica Beach closures are also scheduled for September 29 and 30 as backup dates. This will be Starship’s first revenue generating mission.

The license was the missing piece after SpaceX completed a full wet dress rehearsal with Booster 21 and Ship 41 on September 24. At the time, the company said the flight remained on track pending regulatory approval. Because Flight 14 flies an orbital profile, the FAA had to sign off on a modified license that met its safety, payload and financial responsibility requirements.

Observers combing through the new FAA paperwork also noticed that lightning no longer appears among Starship’s listed launch hazards. If that holds, it matters more for where Starship is headed than for Monday’s attempt. Florida and Louisiana, home to LC-39A and the planned Starbase Louisiana site, see some of the most frequent lightning in the United States.

SpaceX tells the FCC that Starship Flight 14 is going to orbit

Flight 14 is the mission SpaceX has been building toward for months. Ship 41 will carry 26 Starlink V3 satellites, the first operational V3 units to be deployed, and attempt roughly six orbits at about 275 kilometers over a flight lasting just under 10 hours. SpaceX says the ship will only perform its orbital insertion burn after flight controllers confirm enough hardware redundancy remains for the deorbit burn at the end of the mission. Ship 41 is targeting a splashdown in the Pacific west of Chile, while Super Heavy will return to the Gulf of Mexico.

The date carries some symbolism as well. A Monday launch would come 10 years and one day after Elon Musk first presented the Interplanetary Transport System, the design that became Starship, at the International Astronautical Congress in Guadalajara, Mexico.

SpaceX has not announced what comes next, but air traffic planning slides reported this week, list Flight 15 no earlier than October 19 and a first Starship launch from LC-39A in Florida no earlier than October 30. Both dates depend on how Monday goes.

SpaceX completes another secret Pentagon launch, adding to suspected Starshield buildout

SpaceX launched the classified USSF-385 mission from Vandenberg, landing its booster on a tenth flight.

SpaceX launched another classified mission for the U.S. Space Force from California early Saturday morning, and the Falcon 9 booster that carried it landed on a drone ship in the Pacific for the tenth time. The USSF-385 mission lifted off from Space Launch Complex 4E at Vandenberg Space Force Base at 7:00 a.m. PT.

Booster B1100 touched down on Of Course I Still Love You roughly eight and a half minutes after liftoff. It was the booster’s tenth flight and tenth successful landing, following the NROL-95 national security mission and eight Starlink launches. Its previous flight, a Starlink Group 15 mission on August 22, came just 35 days earlier. SpaceX ended its livestream shortly after the landing, which is standard for classified payloads, and neither the company nor the Space Force has said what the rocket carried.

USSF-385 is the fourth Space Force launch from the same Vandenberg pad in roughly six weeks, following USSF-366 on August 15, USSF-153 on September 10, and USSF-259 on September 17. When SpaceX flew USSF-366 in August, independent trackers noted that the rocket’s stage drop zones matched SpaceX’s Starlink Group 15 missions, pointing to Starshield, the government version of the Starlink satellite bus. The Space Force later cataloged 23 satellites after both USSF-366 and USSF-153, while USSF-259 placed 17 satellites into a different orbital plane, per KeepTrack. Launch databases describe USSF-385 the same way, though the payload remains officially unidentified.

Starlink’s Starshield wins contract with US Space Force

The cadence lines up with the contracts, because in July, the Space Force awarded SpaceX $1.6 billion in task orders for 18 Falcon 9 missions from Vandenberg through the end of 2027. SpaceX also holds contracts to build pieces of that same network, which pushed its Pentagon contract total for 2026 past $8 billion.

Saturday’s flight was also the sixth and final Falcon 9 launch from Vandenberg in September, according to Spaceflight Now, while only one Falcon 9 flew from the East Coast this month as SpaceX shifts its Florida infrastructure toward Starship. Launch trackers list it as SpaceX’s 112th mission of 2026 and the 108th Falcon 9 flight of the year, with SLC-4E turned around about six and a half days after its previous launch.

The West Coast pad will not stay quiet for long, considering SpaceX has another Starlink mission scheduled from SLC-4E on September 30. Meanwhile, in Texas, the company is two days away from Starship Flight 14, which is targeting Monday at 7:15 a.m. CT for the vehicle’s first attempt to reach orbit.

Tesla hints at new Roadster design in surprise clip

Tesla closed out its Semi event in Nevada on Thursday night with a nod to its own history, dropping a short Roadster teaser that suggests the production car will look noticeably different from the prototype first shown in 2017.

“We can’t have a Semi event without the Roadster,” Tesla engineering executive Lars Moravy told the crowd before the clip played. The line was a deliberate callback. Tesla first revealed the next generation Roadster in November 2017 by driving it out of the back of a Semi trailer at the truck’s original unveiling in Hawthorne, California.

The new video opens on trailer doors swinging apart in the dark. A thin white light bar glows across what appears to be the nose of the car, Tesla and SpaceX logos flash over the frame, and the Roadster name appears before the clip ends on “See you next week.” Tesla posted the nine second clip on X after the livestream wrapped.

The light bar is the most concrete design detail so far. The 2017 prototype used two separate curved headlamp pods, while a connected front light strip would bring the Roadster in line with the Cybertruck, Cybercab, Semi, and refreshed Model Y. Sawyer Merritt was among the first to point out what looked like part of a SpaceX logo in the video, something Tesla has not addressed.

That logo fits the buildup around the optional SpaceX Package, which Elon Musk has long said would use cold gas thrusters to improve acceleration and possibly allow the car to briefly leave the ground. Tesla’s “Go for launch” post on September 12 set the October 1 date, and invitations sent to reservation holders place the event in Waco, Texas, at 8:30 p.m. Eastern. Waco sits roughly 20 minutes from SpaceX’s McGregor rocket test site, where the FAA has put a temporary flight restriction in place from September 18 through October 2, covering a 1.5 nautical mile radius from the surface up to 10,000 feet.

Tesla is also taking money ahead of the reveal. The company reopened Roadster reservations earlier this week with a $5,000 refundable card payment, followed by a $45,000 wire transfer due within 10 days. That puts buyers at $50,000 committed before Tesla has published a price.

The original pitch set a high bar: 0 to 60 mph in 1.9 seconds before any upgrades, 620 miles of range, a top speed above 250 mph, and production in 2020. That timeline has slipped repeatedly, and Tesla has since pointed to production at Gigafactory Texas no earlier than 2027. The company has said next Thursday’s event will include pricing, specifications, and production targets, the three details original reservation holders have been waiting on for nearly nine years.
