"SpaceX Starship is a BIG MISTAKE!", Scientists revealed...

SpaceX has recently faced growing criticism from both current and former NASA officials, including the agency's acting administrator, Sean Duffy, for falling behind on developing its Starship human landing system, the version built for NASA's return to the Moon. But the truth is, the skepticism didn't start now. From day one, the spacecraft has split the science world in two. Some see it as the future of spaceflight. Others call it a billion dollar mistake. Critics say it's too big, too risky, too unrealistic. But SpaceX has heard all that before. Rockets that land themselves? Impossible. Until they did it. Reusable boosters? A fantasy. Until Falcon 9 made it routine. Now, with Starship, SpaceX isn't answering critics with words. It's answering with fire and steel. Every launch, every explosion, every rebuild sends the same message. The future of space belongs to those bold enough to build it. And with the latest progress on the lunar Starship, SpaceX is beginning to chip away at the doubts that have followed it for years. Find out how in today's TechMap episode. Nine years ago, Elon Musk took the stage and unveiled something bold. His plan to make humanity multi-planetary. He called it a roadmap for colonizing Mars, powered by a massive spacecraft we now know as Starship. It was one of those moments that got everyone talking. And honestly, it still does. Since that announcement, public interest hasn't faded. It's only grown stronger. Every time SpaceX rolls out a new Starship prototype, or fires one into the sky, millions tune in to watch the spectacle live on X. And it's not hard to see why. Starship is unlike anything we've ever built. It's the largest, most powerful rocket ever constructed, capable of lifting over 200 metric tons to orbit. But the real game-changer is reusability. Musk's goal is to cut launch costs from billions down to around $10 million. A staggering drop that could make Mars missions, and really any space mission, far more achievable. It's a shift that could reshape the entire launch industry, turning what was once astronomically expensive into something routine. And beyond the economics, Starship has captured imaginations with its wild engineering. Like Mechazilla, the massive launch tower designed to catch the rocket mid-air on its return. If that wasn't enough, NASA's already placed its bet. The agency selected a modified version of Starship for its upcoming lunar landings, putting SpaceX right in the middle of a new race back to the moon, this time with China watching closely. But of course, not everyone shares Musk's optimism. His bold Mars ambitions have sparked just as much skepticism as excitement, especially among scientists and spaceflight experts. In 2024, Musk posted something on X that got people talking again. He wrote, SpaceX plans to launch about 5 uncrewed Starships to Mars in 2 years. If those all land safely, then crewed missions are possible in 4 years. If we encounter challenges, then the crewed missions will be postponed another 2 years. It is only possible to travel from Earth to Mars every 2 years, when the planets are aligned. According to that timeline, the first human flight to Mars could happen sometime between 2028 and 2030, right in line with Musk's earlier target of 2029. But not everyone is convinced. Professor Brian Cox, one of the most recognizable science communicators in the UK, thinks Musk might be overestimating how fast this can happen. SpaceX are a remarkable company, he said. They've done something astonishing, transforming the economics of spaceflight. You never know with them, they're really good engineers. But my guess is that Musk's prediction is optimistic. Cox added that even if the technology were ready tomorrow, he wouldn't be packing his bags for Mars just yet. I'd be surprised to see anyone there before the 2040s at the earliest, he said. Though, I'd love to be wrong. I think it's even more difficult than going to the moon was in the 1960s. Apollo was at the edge of our capabilities in the 60s. It was right at the edge of available technology. And I think Mars is perhaps even slightly beyond that at the moment. I wouldn't be surprised if we've started sending the infrastructure within the next 10 years. When it comes to whether Musk's timeline could actually work, opinions are divided. Robert Moses, a retired aerospace engineer from NASA's Langley Research Center, thinks it's not entirely out of reach. He says the plan might be okay, and that it still gives Musk one more opportunity before 2033 to throw everything possible over to Mars. But that optimism comes with a long list of technical hurdles, the kind that keep aerospace engineers up at night. Moses and others warned that SpaceX still has to solve a number of unprecedented challenges before anyone can safely make the trip to Mars, let alone live there. Any one of these problems could turn into a mission-ending disaster. For this plan to work, SpaceX's massive Starship Super Heavy rocket has to perform as reliably as the company's tried-and-true Falcon 9. But that's a high bar. According to Scott Hubbard, former director of NASA's Ames Research Center and now director emeritus at Stanford's Center of Excellence for Commercial Space Transportation, SpaceX may be running into the limits of its famous build-a-little, test-a-little, fail-a-little approach. With Falcon, there was a distinct improvement from flight-to-flight, Hubbard said. Until now, it's had something like 150 successful missions without a problem. Starship is nowhere near that at this point. In fact, Starship hasn't even reached orbit yet. Across 11 integrated test flights so far, the giant rocket has only followed suborbital trajectories, sending its upper stage on controlled splashdowns in the Indian Ocean. Reaching orbit is only the first step. Once there, Starship faces an even bigger challenge, refueling in space. To make the journey to Mars, Starship needs to dock with a series of orbital tankers to top off its enormous fuel tanks, about 933 metric tons of liquid oxygen and 267 metric tons of liquid methane. That's a full load of propellant, and according to Robert Moses, it's essential for shortening the trip to just three or four months. The faster the transit, the less time astronauts spend exposed to dangerous cosmic radiation. But pulling that off won't be easy. Starship needs 1,200 tons of propellant, and you've got a tanker that takes 100 tons at a time, explains Donald Rapp, a chemical engineer and former NASA Jet Propulsion Laboratory consultant for the Mars 2020 mission. That means 12 separate tanker launches for every Mars-bound Starship. Run those numbers again. If SpaceX really plans to send five Starships in 2026, that's 60 tanker launches in total. Experts suppose that it could be an incredible logistical challenge and a perfect setup for Murphy's Law to make an appearance. It would also put unprecedented pressure on SpaceX's ground operations and launch infrastructure. Then there's another problem. What happens when Starship actually gets to Mars? Dr. Robert Zubrin, president of the Mars Society and an aerospace engineer, says the size of Starship might end up working against it. Because it's so massive, he explains, it takes a great deal of facilities to refuel it. I anticipate that the few Starships that first land on Mars will stay on Mars. Zubrin argues that building a smaller, mini-Starship, one that could make the round trip, might be the smarter move. It would have tremendous advantages for an exploration architecture, he says. It wouldn't need a big base to refuel and come back. But Musk doesn't seem interested in that idea. His philosophy has always been to build one system that can do it all, rather than splitting resources between two. Still, Zubrin admits, if anyone could build both versions, it's SpaceX, especially seeing how quickly they develop things. Now, even if Starship does reach orbit and lines up all those tanker ships, the refueling itself is still a massive unknown. On paper, the maneuver makes sense. In practice, though, it's almost completely untested. There's been a lot of models that have been developed, says William Notterdonato, a former NASA engineer and now CEO of ETA Space, a company in Florida working on small-scale cryogenic propellant transfers in orbit. But nobody's really been able to accurately anchor those models in flight data using a real cryogenic fluid. That's a polite way of saying no one's ever done this before. SpaceX is essentially developing the entire system from scratch, and that's already caused some delays. For example, NASA's Artemis III mission, which relies on a lunar version of Starship to land astronauts on the moon, has had its timeline pushed back, in part because in-orbit refueling isn't ready yet. Still, there's progress. During a 2024 Starship test, SpaceX successfully transferred an undisclosed amount of liquid oxygen between two internal tanks. A small step, but a crucial one. The company plans to attempt its first full-scale transfer between two spacecraft in 2026. And it's not just refueling. Behind the scenes, the company has been steadily checking off milestone after milestone for the lunar Starship, the version that will carry astronauts back to the moon. The list is long, but a few stand out. And together they paint a picture of just how ambitious this program really is. They've built and tested full-scale cabin modules, complete with working life support systems, oxygen, air circulation, humidity, temperature control, everything you'd need to keep a crew alive on the moon. They've created a new docking adapter, inspired by the Dragon 2 capsule, so Starship can link up directly with NASA's Orion spacecraft in orbit. To prepare for lunar landings, engineers dropped full-size landing legs onto simulated moon dust to see how they'd perform. They fine-tuned Raptor engines to throttle precisely for a soft touchdown, and even tested shielding materials to protect against micrometeoroid strikes and extreme heat. There's also the software side, the brains of the operation. Teams have run exhaustive checks on navigation sensors, radar systems, and landing algorithms, while reviewing the underlying software architecture that handles everything from fault detection to mission control. And then there are the small but crucial details that make a mission human. An elevator system to move astronauts and cargo down to the lunar surface. Medical and telemedicine systems tested in flight-like conditions. Even full-scale simulations with NASA and Axiom crews practicing procedures for real missions. SpaceX has also tested cold-starting Raptor engines after long exposure to space, power modules for the orbital fuel depot, and communication systems to keep everything linked to Earth. It's a dizzying list of breakthroughs, but it shows one thing clearly. Starship is no longer just a wild concept on Elon Musk's slides. It's turning into real hardware, real systems, and real results. While many of SpaceX's remaining HLS contract milestones are tied to flight tests, such as a ship-to-ship propellant transfer demonstration, SpaceX has begun fabricating a flight article Starship HLS Cabin that will include functional avionics and power systems, crew systems and mechanisms, environmental control and life support systems, cabin and crew communications systems, and a cabin thermal control system.
