Elon Musk: Faulty Strut May Have Led To Falcon 9 Launch Failure 220

garyisabusyguy writes: This Forbes article provides the best analysis of the loss of the last Falcon 9 mission based on information released by Elon Musk to reporters. Highlights include:
  • 1. Sound triangulation led them to identify a strut holding helium tank as root cause where the falling helium tank pinched a line causing overpressure in the LOX tank.
  • 2. The failure occurred at 2,000 pounds of force, and the struts were rated at 10,000 pounds of force. They initially dismissed this as a cause until sounds triangulation pointed back to the strut
  • 3. Further testing of struts in stock found one that failed at 2,000 pounds of force, with further analysis identifying poor grain structure in the metal, which caused weakness
  • 4. It will be months before the next launch while SpaceX goes over procurement and QA processes all struts and bolts, and re-assesses any "near misses" with Air Force and NASA
  • 5. Next launch will include failure mode software, which will allow recovery of the Dragon module during loss of the launch vehicle since they determined that it could have saved the Dragon module in this lost mission

The Brainteaser Elon Musk Asks New SpaceX Engineers 496

Nerval's Lobster writes: The latest biography of Elon Musk, by technology journalist Ashlee Vance, provides an in-depth look into how the entrepreneur and tech titan built Tesla Motors and SpaceX from the ground up. For developers and engineers, getting a job at SpaceX is difficult, with a long interviewing/testing process... and for some candidates, there's a rather unique final step: an interview with Musk himself. During that interview, Musk reportedly likes to ask candidates a particular brainteaser: "You're standing on the surface of the Earth. You walk one mile south, one mile west, and one mile north. You end up exactly where you started. Where are you?" If you can answer that riddle successfully, and pass all of SpaceX's other stringent tests, you may have a shot at launching rockets into orbit.

SpaceX Falcon 9 Launches Dual Satellite Mission 23

JoeSilva writes SpaceX successfully launched two satellites towards Geosynchronous Orbit. There's already a video of one deployment. Word is the launch went very smoothly and bodes well for their next launch in three weeks, as they work to fulfill what is now a very full launch manifest. In addition Elon had one more thing to share: "Upgrades in the works to allow landing for geo missions: thrust +15%, deep cryo oxygen, upper stage tank vol +10%."

Elon Musk To Write a Book About Earth Sustainability and Mars Colonization 131

MarkWhittington writes Elon Musk has taken on quite a number of projects with a goal of changing the world while making lots of money doing so. He proposes to revolutionize space travel through his commercial launch company, SpaceX. His more earthly endeavors have included electric cars, home solar power, a transportation system called the Hyperloop, a space based Internet and, most recently, a battery that can power a house. Now, according to a story in Business Insider, Musk will open his mind on his views on "sustainability" was well as Mars colonization in book form.

Elon Musk Plans To Build Hyperloop Test Track 165

An anonymous reader writes that Elon Musk wants to speed up the development of his proposed 800-mph tube transport. "Billionaire and entrepreneur Elon Musk is getting more hands-on with the Hyperloop. Musk, who heads up both space transportation outfit SpaceX and electric-vehicle maker Tesla Motors, casually announced via Twitter on Thursday that he's decided to help accelerate development of his vision for near-supersonic tube transportation, first outlined in August 2013. Musk said he will build a five-mile test track for the still-theoretical system for students and companies to use. A possible location would be Texas, he added, where presumably there is plenty of flat land to go around."

Elon Musk Talks "X-Wing" Fins For Reusable Rockets, Seafaring Spaceport Drones 96

An anonymous reader writes Elon Musk sent a number of tweets recently in which he detailed a program to test the function of "X-Wing" style grid fins that could help spacecraft navigate upon re-entry. The tweets describing how it would work, also include an autonomous seafaring platform, which can hold its position within three meters even in a heavy storm, that would act as a landing pad. From the article: "The SpaceX reusable rocket program has been progressing with varying results, including an explosion over Texas back in August. While the incident didn't result in any injury or even 'near injuries,' Musk conceded in a tweet that this was evidence that '[r]ockets are tricky.' An earlier test flight from this summer involving an ocean splashdown was considered more successful, proving that the Space X Falcon 9 booster could re-enter earth's atmosphere, restart its engines, deploy its landing legs and make a touch down at 'near zero velocity.'"

Elon Musk Warns Against Unleashing Artificial Intelligence "Demon" 583

An anonymous reader writes Elon Musk, the chief executive of Tesla and founder of SpaceX, said that artificial intelligence is probably the biggest threat to humans. "I think we should be very careful about artificial intelligence. If I had to guess at what our biggest existential threat is, it's probably that. So we need to be very careful with artificial intelligence." he said. "I'm increasingly inclined to think that there should be some regulatory oversight, maybe at the national and international level, just to make sure that we don't do something very foolish. With artificial intelligence we're summoning the demon. You know those stories where there's the guy with the pentagram, and the holy water, and he's like — Yeah, he's sure he can control the demon? Doesn't work out."

Elon Musk: I'll Put a Human On Mars By 2026 275

An anonymous reader writes Elon Musk says that he'll put the first human boots on Mars well before the 2020s are over. "I'm hopeful that the first people could be taken to Mars in 10 to 12 years, I think it's certainly possible for that to occur," he said. "But the thing that matters long term is to have a self-sustaining city on Mars, to make life multiplanetary." He acknowledged that the company's plans were too long-term to attract many hedge fund managers, which makes it hard for SpaceX to go public anytime soon. "We need to get where things a steady and predictable," Musk said. "Maybe we're close to developing the Mars vehicle, or ideally we've flown it a few times, then I think going public would make more sense."

Musk Will Open Up Tesla Supercharger Patents To Spur Development 230

redletterdave (2493036) writes "Elon Musk has said repeatedly he wants to 'do something controversial' with Tesla's collection of electric car patents, but he finally offered specifics at the UK launch of his Tesla Model S on Sunday. The Tesla Motors CEO said he would like to open up the designs for his Supercharger systems — the free fast-charging stations designed to quickly refuel Tesla's electric cars — to create a standard for other car makers to use. Musk previously said he didn't want Superchargers to become a 'walled garden.'"

Elon Musk Talks Tesla, Apple, Model X 99

Nerval's Lobster writes "Tesla CEO Elon Musk admitted in a Bloomberg interview that he had engaged in 'conversations' with Apple, but refused to disclose the content of those talks. Rumors have circulated for several days that Apple executives met with Musk last spring about a possible acquisition. An anonymous source with knowledge of those discussions told SFGate.com that discussions included Adrian Perica, who heads up Apple's M&A division, and possibly Apple CEO Tim Cook. 'Both [Tesla and Apple] have built brands based on advanced engineering and stylish user-friendly design,' the newspaper noted. 'And each company has become a symbol of Silicon Valley innovation—even among people who don't own their products.' But in the interview, Musk framed an acquisition as 'very unlikely,' mostly because it would distract Tesla from its goal of building an affordable electric car. 'I don't see any scenario,' he added, in which Tesla could juggle the issues associated with a takeover while producing vehicles that met his perfectionist standards. He did suggest, however, that Apple's iOS and Google Android could find their respective ways into Tesla's in-vehicle software. Tesla executives once considered integrating an early version of Android into the company's first electric cars, but the software ultimately wasn't ready to serve as an automotive application. Nonetheless, Musk could see iOS or Android within the context of a 'projected mode or emulator' that would allow someone to use applications while driving, although 'that's peripheral to the goal of Tesla.'"

Elon Musk Says Larger Batteries Might Be On the Way 191

mknewman writes "Elon Musk intimated that more-powerful batteries could be on the way for the Model S. The most potent battery pack currently offered in the Model S holds 85 kWh of juice, or enough for 265 miles of driving. Musk wasn't terribly specific, however: 'There is the potential for bigger battery packs in the future, but it would probably be maybe next year or something like that. The main focus is . . . how do we reduce the cost per kWh of storage in the battery pack?' In other words, Musk seems less concerned with stronger battery packs than making cheaper battery packs for the upcoming mid-size sedan, which is expected to be unveiled at the 2015 Detroit auto show. 'Our goal is to drop the cost per kWh by 30 percent to 40 percent.'"

How Elon Musk Approaches IT At Tesla 231

onehitwonder writes "In short, they build it themselves. When Tesla Motors needed to improve the back-end software that runs its business, CEO Elon Musk decided not to upgrade the company's SAP system. Instead, he told his CIO, Jay Vijayan, to have the IT organization build a new back-end system, according to The Wall Street Journal. The company's team of 25 software engineers developed the new system in about four months, and it provided the company with speed and agility at a time when it was experiencing costly delivery delays on its all-electric Model S."

Elon Musk's New Hologram Project Invites 'Iron Man' Comparisons 135

Nerval's Lobster writes "In the 'Iron Man' trilogy, billionaire inventor Tony Stark uses a gesture-controlled hologram to draft new designs of the titular armor, sending virtual parts flying around his lab with the flick of a wrist. Tesla and SpaceX CEO Elon Musk—who is often compared to Stark by the tech press—is apparently creating the real-life equivalent of that fictional hologram system. 'We figured out how to design rocket parts just w hand movements through the air (seriously),' he Tweeted August 23. 'Now need a high frame rate holograph generator.' In a follow-up Tweet, he added: 'Will post video next week of designing a rocket part with hand gestures & then immediately printing it in titanium.' But Musk has no plans to actually make an Iron Man-inspired suit of armor. 'I am not going to make an IM suit,' he wrote on Twitter, 'however design by hand-manipulated hologram is actually useful.'"

Elon Musk Hates 405 Freeway Traffic, Pays Money To Speed Construction 431

S810 writes "Elon Musk, one of the main people behind PayPal, Space Exploration Technologies and Tesla Motors, has paid $50,000 to help Los Angeles speed up construction of the 405 Freeway, making it better and says that he will pay more if needed. From the article: 'Musk said he is open to pay the cost of adding workers to the widening project "as a contribution to the city and my own happiness. If it can actually make a difference, I would gladly contribute funds and ideas. I've super had it." — Musk quips that it's easier getting rockets into orbit than navigating his commute between home in Bel-Air and his Space Exploration Technologies factory in Hawthorne.' For those who aren't familiar with this issue, the 405 Freeway runs from the northern end of the San Fernando Valley all the way down to El Toro and runs by LAX. Residents are getting frustrated that this widening project is over budget and well over the anticipated time frame that it was supposed to completed by."
