A SpaceX Falcon 9 booster had all four of its landing legs successfully retracted after a flawless fourth launch and landing, highlighting the impressive margins and durability of the rocket’s upgraded Block 5 design.

On April 22nd, Falcon 9 booster B1051 lifted off on its fourth orbital-class mission – also its second 60-satellite Starlink launch this. Around eight minutes later, B1051 successfully landed aboard drone ship Of Course I Still Love You (OCISLY), ending a back-to-back streak of failed ocean recoveries for SpaceX and verifying that the cause of a March 2020 in-flight engine failure had been rectified. After the loss of booster B1056 and B1048 in February and March, it was also simply a relief to have B1051 safe and sound aboard OCISLY, ensuring that the rocket should be able to support another launch in the near future.

After sailing in port on April 26th, SpaceX technicians lifted a booster off of drone ship OCISLY’s deck for the first time since late January – coincidentally (or maybe not) also Falcon 9 B1051. Two days after its arrival in port and transfer onto dry land, SpaceX successfully retracted all of the massive booster’s landing legs in less than three hours and had it ready for transport less than two hours after that. While B1051’s brisk fourth recovery didn’t break any records, it still serves as a reminder of Falcon 9’s impressive durability in light of the landing it experienced just ~85 days prior.

B1051’s successful leg retraction after its fourth launch and landing is particularly impressive for one main reason: after its third launch, the booster suffered perhaps the hardest drone ship landing any Block 5 rocket has thus far experienced.

Taken in March 2019 and February 2020 after Falcon 9 B1051’s first and third launches and landings, the photo below reveals just how hard a landing B1051 experienced after its Starlink-4 launch. Built almost entirely out of carbon fiber composites and mounted directly to the rocket’s tank walls, Falcon’s telescoping landing legs rely on something known as a ‘crush core’ – made out of aluminum honeycomb – that’s designed to intentionally collapse under a very specific amount of stress.

The crush core is situated in the very tip of the cylindrical leg booms and is easily visible above on the left, while it has nearly disappeared in the right (after) photo after an exceptionally hard landing used up what looks like 90+% of the booster’s safety margin. In other words, if B1051 had landed just a little harder after its third launch, it’s possible that the booster’s landing leg booms would have used up all their crush cores and been driven into the kerosene tank they attach to, potentially totaling the Falcon 9 first stage.

Instead, while clearly a rough landing, B1051 appears to have had its landing leg crush cores replaced and was made ready for another Starlink launch less than three months after that exceptionally hard landing. In other words, despite the rarity of similar hard landings over dozens of recent booster landings, SpaceX was apparently almost entirely unconcerned about the rocket’s state.

As usual, the company almost certainly checked the structural integrity of B1051’s major welds and landing leg hardware before certifying the vehicle for its fourth launch, but the fact that its reuse was so seemingly unexceptional is a testament to the sheer durability of SpaceX’s reusable rocket boosters. Thanks to the modularity of its design, B1051 should have no trouble performing at least several more orbital-class launches over the next several months (if not years). More likely than not, the Falcon 9 Block 5 rocket will fly again just two or so months from now on another Starlink mission, of which SpaceX has 20+ nominally scheduled this year alone.

SpaceX just got pulled into the biggest Weapons Program in U.S. history

SpaceX joins the Golden Dome software group, deepening its role in America’s most expensive defense program.

SpaceX has joined a nine-company group developing the core operating software for the Golden Dome, America’s next-generation missile defense system. According to a Bloomberg report, SpaceX is focused on integrating satellite communications for military operations and is working alongside eight other defense and artificial intelligence companies, including Anduril Industries, Palantir Technologies, and Aalyria Technologies, to build software connecting missile defense capabilities.

The Golden Dome concept dates back to President Trump’s 2024 campaign, and on January 27, 2025, he signed an executive order directing the U.S. Armed Forces to construct the system before the end of his term. The system is planned to employ a constellation of thousands of satellites equipped with interceptors, with data centers in space providing automated control through an AI network.

Space Force Gen. Michael Guetlein, director of the Golden Dome initiative, has described the software layer as a “glue layer” that would enable officers to manage and control radars, sensors, and missile batteries across services. The consortium is aiming to test the platform this summer.

Trump selected a design in May 2025 with a $175 billion price tag, expected to be operational by the end of his term in 2029, though the Congressional Budget Office projected the cost could reach $831 billion over two decades.

The Golden Dome role is only the latest in a string of military wins for SpaceX. As Teslarati reported, the U.S. Space Force awarded SpaceX a $178.5 million task order on April 1, 2026 to launch missile tracking satellites for the Space Development Agency, covering two Falcon 9 launches beginning in Q3 2027. That came on top of more than $22 billion in government contracts held by SpaceX as of 2024, per CEO Gwynne Shotwell, spanning NASA resupply missions, classified intelligence satellites through its Starshield program, and military broadband.

The accumulation of defense contracts, now including a seat at the table on the most expensive weapons program in U.S. history, positions SpaceX as the dominant infrastructure provider for American national security in space. With a SpaceX IPO still on the horizon, each new contract adds weight to what is already one of the most consequential companies in aerospace history, raising real questions about how much of America’s defense architecture will depend on a single private operator before it ever trades publicly.

Tesla pulls back the curtain on Cybercab mass production

Tesla’s Cybercab drives itself off the Gigafactory Texas line in a striking new production video.

Tesla has provided a first look from inside a production Cybercab as it drove itself off the assembly line at Gigafactory Texas. The video footage, posted on X, opens on the factory floor with robotic arms and assembly equipment visible through the Cybercab windshield, and follows the car through a branded tunnel marked “Cybercab”, before autonomously navigating itself to a holding lot.

The first Cybercab rolled off the Giga Texas production line on February 17, 2026, with Musk writing on X, “Congratulations to the Tesla team on making the first production Cybercab.” April marked the official shift to volume production. The Giga Texas line is being prepared to produce hundreds of units per week, with 60 units already spotted on the Gigafactory campus earlier this month.


The Cybercab was first revealed publicly at Tesla’s “We, Robot” event in October 2024 at Warner Bros. Studios in Burbank, California, where 20 pre-production units gave attendees rides around the studio lot. Musk said he believed the average operating cost would be around $0.20 per mile, and that buyers would be able to purchase one for under $30,000. The two-seat design is deliberate. Musk noted that 90 percent of miles driven involve one or two people, making a compact two-passenger vehicle the most efficient configuration for a fleet-scale robotaxi. Eliminating rear seats also removes complexity and cost, supporting that sub-$30,000 target.

Tesla’s annual production goal is 2 million Cybercabs per year once several factories reach full design capacity. The Cybercab has no steering wheel, no pedals, and relies entirely on Tesla’s vision-based FSD system. What the video shows is the first evidence of that system working not as a demo, but as a production reality, driving itself off the line and into the world.

Elon Musk talks Tesla Roadster’s future

Elon Musk confirmed the Roadster as Tesla’s last manually driven car, with a debut coming soon.

During Tesla’s Q1 2026 earnings call on April 22, Elon Musk made a brief but notable comment about the long-awaited next generation Roadster while describing Tesla’s future vehicle lineup. “Long term, the only manually driven car will be the new Tesla Roadster,” he said. “Speaking of which, we may be able to debut that in a month or so. It requires a lot of testing and validation before we can actually have a demo and not have something go wrong with the demo.”

That single statement is the entire Roadster update from yesterday’s call, and while it represents another timeline shift, it comes as no surprise with Tesla heads-down-at-work on the mass rollout of its Robotaxi service across US cities, and the industrial scale production of the humanoid Optimus.

The fact that Musk specifically framed the Roadster as the last manually driven Tesla is significant on its own. As the rest of the lineup moves toward full autonomy, the Roadster becomes something rare in the Tesla-sphere by keeping the driver in control. Driving enthusiasts who buy a $200,000 supercar are not doing so to be passengers. They want the physical connection to the road, the feel of acceleration under their own input, and the experience of controlling something with that level of performance. FSD, however capable it becomes, removes that entirely. The Roadster signals that Tesla understands this distinction and is building a car specifically for the people who consider driving itself the point.

Tesla isn’t joking about building Optimus at an industrial scale: Here we go

The specs for the Roadster Musk has teased over the years are genuinely unlike anything in production. The base model targets 0 to 60 mph in 1.9 seconds, a top speed above 250 mph, and up to 620 miles of range from a 200 kWh battery. The optional SpaceX package takes it further, rumored to add roughly ten cold gas thrusters operating at 10,000 psi, borrowed directly from Falcon 9 rocket technology. With thrusters, Musk has claimed 0 to 60 mph in as little as 1.1 seconds. In a 2021 Joe Rogan interview he went further, stating “I want it to hover. We got to figure out how to make it hover without killing people.” Tesla filed a patent for ground effect technology in August 2025, suggesting the hover concept has not been abandoned. The starting price remains $200,000, with the Founders Series requiring a $250,000 full deposit. Some reservation holders placed those deposits in 2017 and are approaching a full decade of waiting.

With production now targeted for 2027 or 2028 at the earliest, the Roadster remains Tesla’s most audacious promise and its longest-running delay. But if what Musk is testing lives up to even half of what he has described, the demo alone should be worth waiting for.
