SpaceX’s Elon Musk says Raptor will be installed on Starship prototype this week
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
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 nails “Lucky 13” astronaut launch, leaning into Tesla tradition and superstition
SpaceX launched Crew-13 astronauts to the ISS Thursday, setting up a record fast Dragon docking.
SpaceX launched NASA’s Crew-13 mission to the International Space Station on Thursday morning, getting four astronauts to orbit despite a forecast of thunderstorms and gusty winds that had threatened to push the flight to Friday.
Falcon 9 lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station at 11:10 a.m. ET carrying Dragon Grace, NASA confirmed. On board are NASA commander Jessica Watkins, NASA pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov. The first stage booster, B1101, landed at Landing Zone 40 beside the pad on its third flight after previously supporting Crew-12 and a Starlink mission.

It was the first spaceflight for Delaney, Kutryk and Teteryatnikov. Watkins, who flew on Crew-4 in 2022, became the first NASA astronaut to launch aboard a Crew Dragon twice.
Before launch, the crew rode to the pad in Teslas, a tradition on NASA’s SpaceX crew flights since 2020. This time the cars carried specialty plates reading “Lucky 13.” Watkins said the mission patch leans into the number on purpose, as a nod to Apollo 13 and the resilience of that crew.
Grace is now on a short trip to the station. Docking at the forward port of the Harmony module is scheduled for about 7 p.m. ET, roughly 7 hours and 50 minutes after liftoff, which Space.com notes would be the fastest Crew Dragon transit to the ISS yet. Most Dragon flights take around 15 to 24 hours to catch the station. Hatch opening is planned for 8:25 p.m. ET.
The launch came more than two weeks later than originally planned. An oxidizer leak was found in Grace’s propulsion system in August, and NASA and SpaceX added time for tests. That pushed back the return of Crew-12, which has been aboard the station since February and is now set to splash down off Southern California next week. Crew-13 is expected to stay about six months.

SpaceX already holds NASA orders for crew rotations through Crew-17, while Boeing is preparing an uncrewed Starliner flight to the station as early as December.
Crew-13 was only the first of three SpaceX launches planned for Thursday, as Teslarati previewed on Wednesday. A Falcon 9 launched its Transporter-18 mission from California today, where Google will be launching its first orbital artificial intelligence (AI) test satellite. Meanwhile, Falcon Heavy is set to launch the classified NROL-97 mission for the National Reconnaissance Office from Launch Complex 39A at 11:53 p.m. ET. Its two side boosters will return to Landing Zones 1 and 2, which means Central Florida could hear up to three sonic booms in a single day. The busy stretch follows Starship’s Flight 14 on Monday, which reached orbit for the first time.

The Pentagon taps Elon Musk to design the battlefield of the future
Hegseth named Elon Musk to help lead Project Meridian, a Pentagon study of future warfare.
Elon Musk has a new role in the Trump administration. Defense Secretary Pete Hegseth announced on war.gov Wednesday that Musk will help lead Project Meridian, a new Pentagon study meant to identify the weapons and technologies the U.S. military will need to fight wars decades from now.
Hegseth unveiled the project during his State of the Force address at Marine Corps Base Quantico in Virginia. Musk will direct the effort alongside Anduril founder Palmer Luckey and former House Speaker Newt Gingrich, working under Pentagon Chief Technology Officer Emil Michael. All three men were in attendance, and Hegseth said their first meeting would take place directly after the speech inside a secure compartmented facility, according to The Hill.
Hegseth said the group “will be focused on discovering, developing, and fielding the weapons and systems that our children and our grandchildren will need in their lifetimes, without any creative limitations or restrictions, on any future battlefield, from under the Earth to beyond the Moon.” He added that Meridian is not meant to produce new strategy or policy documents.
SpaceX to become America’s Military data backbone for missiles, drones, and warfighters
A memo released after the announcement gives Michael until January 28, 2027, to deliver findings, a window of 120 days. It names artificial intelligence, autonomy, directed energy, robotics and biotechnology as the fields expected to change how wars are fought. The results will come as a public report with a classified annex. The memo says the study will run through a partner organization it does not name, and it does not mention Musk directly. His role comes from Hegseth’s speech and a Pentagon press release.’
Musk had not commented publicly on the appointment as of Wednesday evening. This will be Musk’s first official advisory role in the administration since he left DOGE last year.
The mandate overlaps heavily with Musk’s companies. SpaceX is one of the Pentagon’s largest contractors, with 2026 defense awards topping $8 billion, much of it tied to launches and a suspected Starshield buildout out of Vandenberg. The Pentagon’s release says Meridian will examine domains “from subterranean depths to the cislunar frontier,” which maps onto The Boring Company’s tunneling and Starship’s lunar plans. Tesla’s work on autonomy and Optimus falls within the fields the memo lists.
Meridian was one of six initiatives Hegseth announced Wednesday. Another is a new Autonomous Warfare Command, which the department wants operating as a four-star combatant command by October 1, 2027.
The news lands a day before SpaceX is scheduled to fly a classified National Reconnaissance Office payload on Falcon Heavy, one of three launches the company has planned for Thursday.

SpaceX set to launch astronauts and a classified Falcon Heavy mission on the same day
SpaceX plans three launches Thursday, including Crew-13 astronauts and Falcon Heavy’s first classified NRO mission.
SpaceX is lining up one of the busiest single days in its history, and the company offered a preview on Wednesday morning with a simple post on X: “Sunrise at pad 40.” The video and photos show Falcon 9 standing at Space Launch Complex 40 at Cape Canaveral, roughly a day before it is scheduled to carry four astronauts to the International Space Station.
That launch is only the first of three SpaceX missions planned for Thursday, October 1, across both coasts.

Crew-13 is targeting liftoff at 11:10 a.m. ET, with a backup opportunity Friday at 10:47 a.m. ET. NASA astronaut Jessica Watkins will command the mission, with NASA’s Luke Delaney as pilot and Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov serving as mission specialists. According to NASA, Dragon is set to dock with the forward port of the station’s Harmony module around 8 p.m. ET, less than nine hours after launch. Watkins is the only member of the crew who has flown before, and Kutryk will become the first Canadian to reach orbit through NASA’s Commercial Crew Program.
The Falcon 9 booster is flying for the third time after supporting Crew-12 and a Starlink mission, and it will attempt a landing at Landing Zone 40 beside the pad. That site made its debut in February when the Crew-12 booster touched down there, as Teslarati reported at the time. Crew-13 will relieve the Crew-12 astronauts, who have been aboard the station since the middle of February.
On the West Coast, another Falcon 9 is scheduled to lift off from Vandenberg Space Force Base in a window running from 2:18 to 3:16 p.m. ET, a flight NASASpaceflight lists as a Transporter rideshare mission.
The day is set to close at 11:53 p.m. ET, when Falcon Heavy launches from Launch Complex 39A with NROL-97, the first National Reconnaissance Office payload ever to fly on the rocket. SpaceX rolled the vehicle out to the pad Tuesday night. Its two side boosters, which previously flew GOES-U, ViaSat-3 F3 and NASA’s Roman Space Telescope, will return to Landing Zones 1 and 2, while a new center core will be expended in the Atlantic. The Roman launch took place on August 30, so NROL-97 will come barely a month later as Falcon Heavy’s third flight of 2026 and 14th overall.
NASA taps SpaceX to launch the telescope that could unlock new worlds
If all three Florida boosters land as planned, it would be the first time the Space Coast has seen landings at LZ-40, LZ-1 and LZ-2 on the same day, according to the Orlando Sentinel, which has warned residents in Brevard, Orange and Volusia counties that more than one sonic boom is possible.
The schedule arrives just three days after Starship reached orbit for the first time on Flight 14 from Starbase, Texas, deploying 26 Starlink V3 satellites. If Thursday’s missions stay on time, SpaceX will have flown Starship, Falcon 9 and Falcon Heavy from four different pads in about four days.
Crew-13 is also the start of a longer run for Dragon. NASA recently added Crew-15, Crew-16 and Crew-17 to SpaceX’s contract in a $946 million modification, keeping Dragon as the agency’s only operational ride to the station while Boeing’s Starliner remains grounded.
