Why do SpaceX rockets keep exploding?

Published

May 31, 2025

With yet another failed Starship test this week, in which the ambitious heavy rocket exploded once again, you might reasonably suspect that luck has finally run out for SpaceX.

But this degree of failure during a development process isn’t actually unusual, according to Wendy Whitman Cobb, a space policy expert with the School of Advanced Air and Space Studies, especially when you’re testing new space technology as complex as a large rocket. However, the Starship tests are meaningfully different from the slow, steady pace of development that we’ve come to expect from the space sector.

“The reason a lot of people perceive this to be unusual is that this is not the typical way that we have historically tested rockets,” Whitman Cobb says.

Historically speaking, space agencies like NASA or legacy aerospace companies like United Launch Alliance (ULA) have taken their time with rocket development and have not tested until they were confident in a successful outcome. That’s still the case today with major NASA projects like the development of the Space Launch System (SLS), which has now dragged on for over a decade. “They will take as long as they need to to make sure that the rocket is going to work and that a launch is going to be successful,” Whitman Cobb says.

“This is not the typical way that we have historically tested rockets.”

SpaceX has chosen a different path, in which it tests, fails, and iterates frequently. That process has been at the heart of its success, allowing the company to make developments like the reusable Falcon 9 rocket at a rapid pace. However, it also means frequent and very public failures, which have generated complaints about environmental damage in the local area around the launch site and have caused the company to butt heads with regulatory agencies. There are also significant concerns about the political ties of CEO Elon Musk to the Trump administration and his undemocratic influence over federal regulation of SpaceX’s work.

Even within the context of SpaceX’s move-fast-and-break-things approach, though, the development of the Starship has appeared chaotic. Compared to the development of the Falcon 9 rocket, which had plenty of failures but a generally clear forward path from failing often to failing less and less as time went on, Starship has a much more spotty record.

Previous development was more incremental, first demonstrating that the rocket was sound before moving onto more complex issues like reusability of the booster or first stage. The company didn’t even attempt to save the booster of a Falcon 9 and reuse it until several years into testing.

Starship isn’t like that. “They are trying to do everything at once with Starship,” Whitman Cobb says, as the company is trying to debut an entirely new rocket with new engines and make it reusable all at once. “It really is a very difficult engineering challenge.”

“They are trying to do everything at once with Starship.”

The Raptor engines that power the Starship are a particularly tough engineering nut to crack, as there are a lot of them — 33 per Starship, all clustered together — and they need to be able to perform the tricky feat of reigniting in space. The relighting of engines has been successful on some of the previous Starship test flights, but it has also been a point of failure.

Why, then, is SpaceX pushing for so much, so fast? It’s because Musk is laser-focused on getting to Mars. And while it would theoretically be possible to send a mission to Mars using existing rockets like the Falcon 9, the sheer volume of equipment, supplies, and people needed for a Mars mission has a very large mass. To make Mars missions even remotely affordable, you need to be able to move a lot of mass in one launch — hence the need for a much larger rocket like the Starship or NASA’s SLS.

NASA has previously been hedging its bets by developing its own heavy launch rocket as well as supporting the development of Starship. But with recent funding cuts, it’s looking more and more likely that the SLS will get axed — leaving SpaceX as the only player in town to facilitate NASA’s Mars plans.

But there’s still an awful lot of work to do to get Starship to a place where serious plans for crewed missions can even be made.

“There’s no way that they’re putting people on that right now.”

Will a Starship test to Mars happen by 2026, with a crewed test to follow as soon as 2028, as Musk said this week he’s aiming for? “I think it’s completely delusional,” Whitman Cobb says, pointing out that SpaceX has not appeared to be seriously considering issues like adding life support to the Starship or making concrete plans for Mars habitats, launch and landing pads, or infrastructure.

“I don’t see SpaceX as putting its money where its mouth is,” Whitman Cobb says. “If they do make the launch window next year, it’s going to be uncrewed. There’s no way that they’re putting people on that right now. And I seriously doubt whether they will make it.”

That doesn’t mean Starship will never make it to Mars, of course. “I believe SpaceX will engineer their way out of it. I believe their engineering is good enough that they will make Starship work,” Whitman Cobb says. But getting an uncrewed rocket to Mars within the next decade is a lot more realistic than next year.

Putting people on the rocket, though, is another matter entirely. “If they’re looking to build a large-scale human settlement? That’s decades,” Whitman Cobb says. “I don’t know that I will live to see that.”

A sleek, wearable airbag for cyclists is nearly here

What you’re looking at is a new airbag system integrated directly into a “race-ready” skinsuit, not bolted on like other solutions. It was developed for road cyclists by Van Rysel, with the help of airbag technology specialist In&motion. It’s currently being tested on pro riders ahead of a general consumer release sometime “within the next two years.”

Its development comes after the UCI, pro cycling’s governing body, put out a call in February seeking gear that could help protect riders traveling faster than ever.

The current version is in final validation ahead of potential race deployment. It has a total weight of about 700 grams (500 grams for the airbag components), making it significantly lighter than airbag systems worn in MotoGP, says Van Rysel. And like the proven MotoGP solutions, Van Rysel’s Airbag deploys in just 60 milliseconds after its impact-detection algorithm senses that something has gone horribly wrong.

The skinsuit is design to be aerodynamic and to dissipate heat, with abrasion-resistant materials used to help reduce the risk of road rash and other surface-level skin injuries. The Airbag deploys to protect areas of the upper body not covered by a helmet, including the central core, cervical zone, and spinal line. More extensive protection will be explored in the future.

“Behind every race number, there’s a human being and sadly it is still widely accepted that a rider can lose everything in a fraction of a second due to a crash,” says Van Rysel product manager Jocelyn Bar. “What helmets represented 20 years ago, we think Airbag can represent today, but now, we’re looking beyond the head, we need to protect as much of the body as we can.”

Toyota joins hydrogen truck alliance push

NEWYou can now listen to Fox News articles!

For years, the conversation around clean transportation has leaned heavily toward batteries. Longer range, faster charging, more EVs on the road. That’s been the story. So when Toyota Motor Corporation decided to team up with Daimler Truck and Volvo Group, it raised a fair question: Why double down on hydrogen now? The three companies plan to become equal partners in Cellcentric, a venture focused on fuel-cell systems for heavy-duty trucks and industrial vehicles. The goal is straightforward. Build better hydrogen systems, scale production, and make zero-emissions trucking more realistic. But under the surface, there’s a bigger shift happening.

TOYOTA IS USING AI TO DESIGN BETTER CARS FASTER

Hydrogen trucks vs battery trucks: two paths, not one

Most people think the future of clean vehicles is all battery-powered. That’s partly true, especially for cars. Heavy-duty trucking is a different story. Battery-electric trucks work well for shorter routes. However, long-haul freight brings different challenges. Bigger batteries add weight. Charging takes time. Payload capacity can take a hit. Hydrogen offers a different tradeoff. Fuel-cell trucks can refuel faster and travel longer distances without carrying massive battery packs. That makes them appealing for long-distance shipping, where every minute off the road matters. That’s exactly why this partnership exists. As Daimler Truck’s leadership has emphasized, hydrogen is meant to complement battery-electric systems, not replace them.

Toyota has been quietly building toward this for decades

This move might feel sudden, but Toyota has been laying the groundwork since the early 1990s. The company launched the Toyota Mirai in 2014, one of the first mass-produced hydrogen cars. On paper, it looked like a glimpse into the future. In practice, it struggled to catch on. Sales have been limited, and the biggest issue has not been the car itself. It’s the lack of hydrogen refueling infrastructure. In the U.S., you are mostly limited to California if you want to drive one regularly. Still, Toyota didn’t walk away. Instead, it expanded into trucks. It tested hydrogen-powered heavy-duty vehicles in Europe, partnered with manufacturers, and integrated fuel-cell systems into commercial platforms. That experience is now feeding directly into this new partnership.

Why teaming up makes sense right now

Building hydrogen technology is expensive. Building the infrastructure is even harder. That’s where this alliance comes in. By combining strengths, each company fills a gap. Toyota brings decades of fuel-cell research and manufacturing experience. Daimler Truck contributes deep knowledge of commercial vehicles and logistics. Volvo Group adds global scale and operational reach. Together, they can share costs, accelerate development, and push for infrastructure growth at the same time. That last piece matters most. Hydrogen only works if there are enough places to refuel. Europe is investing heavily in that network, with plans to expand significantly by 2030. This partnership positions all three companies to benefit if that rollout gains traction.

The bigger picture for EVs and clean tech

This does not mean battery EVs are slowing down. Automakers are still investing heavily in electric cars, better batteries and faster charging networks. Toyota itself continues to expand its EV lineup and production capabilities. What this partnership shows is a shift in strategy. Instead of betting everything on one approach, companies are spreading their bets across multiple technologies. That increases flexibility and improves the chances of meeting long-term emissions goals. Hydrogen may not dominate passenger cars. In trucking, though, it has a real opportunity.

What this means to you

Even if you never plan to drive a hydrogen vehicle, this still affects you. Freight powers almost everything you buy. From groceries to electronics, trucks move it across long distances every day. If hydrogen helps clean up long-haul trucking, it could reduce emissions in one of the hardest sectors to fix. It also signals something important about the future of transportation. There won’t be a single solution that works everywhere. Different technologies will serve different needs depending on the job.

Kurt’s key takeaways

At first glance, this move feels like a detour from the EV momentum we’ve been seeing. Look closer, and it starts to make more sense. Heavy-duty transport has unique demands. Hydrogen happens to solve some of them more efficiently than batteries can today. Toyota joining forces with Daimler Truck and Volvo is less about changing direction and more about covering all bases. If infrastructure catches up, this could become one of the more important shifts in clean transportation.

Volvo is also testing hydrogen-powered trucks in real conditions, reinforcing the idea that fuel cells could play a key role alongside battery-electric systems. (Volvo Group)

The Mercedes EQS returns with massive range and charging gains

The Mercedes EQS returns with massive range and charging gains

A year ago, Mercedes-Benz did the prudent thing and paused its EQ lineup of electric vehicles in the US. With customer demand drying up for luxury EVs, and federal incentives getting axed by vengeful Republicans, Mercedes put its first-generation EVs on ice.

But then, in January, Mercedes quietly reintroduced the EQS brand in the US, with The Drive declaring that the “blobs are back” — a reference to the sedan’s much-maligned jelly-bean shape that prioritized aerodynamics over a more traditional profile. But we didn’t yet realize how back the EQS truly was.

Today, Mercedes is reintroducing its electric sedan to a wary, cash-strapped market, and it’s sweetening the pot with a crazy range estimate and an innovative steer-by-wire technology, a first for the German automaker. The 2027 EQS is scheduled to arrive at US dealerships in the second half of 2026.

Mercedes is truly not screwing around with the new EQS. The sedan is estimated to have 925km (575 miles) of range on the WLTP cycle (which tends to be around 10–20 percent more generous than the EPA’s estimates). This can be achieved thanks to a battery with a new chemistry that blends silicon oxide with graphite for the anodes, enabling a usable capacity of 122kWh. Mercedes is also cutting back on its use of cobalt, which has been called the “blood diamond of batteries” due to its ties to human rights abuses.

Charging will be much improved with the refreshed EQS, too. The automaker upgraded architecture to 800 volts, allowing for 350 kW DC fast charging, adding 320 km of range in just 10 minutes. When charging at a 400-volt station, the EQS’s intelligent control system virtually divides the battery into two parts, charing each half with 400 volts and up to 175kW of energy.

The inclusion of steer-by-wire is certainly a big risk. Steer-by-wire, in which the vehicle can be steered electronically rather than through a physical connection between the steering wheel and steering rack, could lead to improved maneuverability and enhanced comfort. Or it could lead to latency issues — although Mercedes says it has thoroughly tested its system for safety. A new steering yoke could help attract race enthusiasts to the dealership. But if you prefer a good old fashioned round-shape steering wheel and reliable electromechanical steering, Mercedes will be happy to sell you an EQS with those too.

The silhouette is still decidedly blob-like, but Mercedes maintains that the one-bow design enables an industry-leading drag coefficient of 0.20 — which is further optimized by “refined exterior mirrors.” This likely helps with range gains, but it could be a tough sell among shoppers who would prefer a few more sharp angles. Mercedes also boosted the regenerative braking power by a third for 385kW of recuperation.

And, of course, there’s more AI integration, including Mercedes’ improved MB.OS operating system that features an AI-powered assistant and over-the-air software updates. The now standard 55-inch Hyperscreen has a “Zero Layer” interface for easier navigation. The operating system uses AI to learn which features you use the most, then surfaces those features as individual widgets on the main screen. Ideally, you don’t have to rummage through too many submenus to find what you want.

Mercedes plans on offering the EQS in a variety of packages. The EQS 450+ is the range leader, with a single, rear-wheel drive motor providing the most efficiency of all the versions. The EQS 500 4MATIC and EQS 580 4MATIC are both all-wheel drive, with an Integrated Disconnect Unit in the front motor. This allows the car to decouple the front motor when not needed to save energy, then activate it at “lightning speed” when the driver needs extra traction or a burst of acceleration. And these models will feature the most regen thanks to their ability to harvest energy from both axles during braking.

The new EQS will come standard with MB.Drive Assist, the automaker’s advanced driver-assist system, that uses 10 cameras and 27 sensors for automatic lane changing, evasive steering, and automated parking. What it’s not, however, is Mercedes’ new Level 2++ feature called Drive Pilot Assist that is rolling out to the CLA electric sedan later this year. The system is similar to Tesla’s FSD in that it can be used hands-free in cities but requires the driver to stay attentive.

Mercedes hasn’t revealed the EQS’s price yet, but it is offering seemingly bottomless options for configuration and customization. This will be through the automaker’s Manufaktur Made to Measure program, which includes over 100 paint colors and other bespoke interior options. This could help shift the vibe around the EQS from a “series production” feel into “tailor-made” territory, allowing for combinations that wouldn’t be found on a standard dealership lot.

All in all, the new EQS will certainly help round out Mercedes’ EV lineup in the US, which is fluctuating right now. The automaker hasn’t said whether it will also resurrect the EQS SUV, or the EQE sedan and SUV. The CLA is doing a good job of turning heads. And Mercedes is sticking to its promise of introducing several new EVs in the US in the coming years, including variants of its GLC crossover and E-Class sedan.
