Humans have figured out lots of ways to shape metal -- casting it with a mold, stamping it, drilling holes and milling surfaces in a machine shop, even zapping it with a laser. Well, now you can add a new method: 3D printing. A number of companies offer metal 3D printing, which creates products and components layer by layer with a computer-controlled system tracing its lineage to ordinary inkjet printers. But on Monday, printing giant HP announced it's entered the market with the ambition to dramatically lower prices, courtesy of a $400,000 product called the Metal Jet. "We're really going...

NATIONAL HARBOR, Md. — SpaceX President and Chief Operating Officer Gwynne Shotwell speaks to audiences around the world and gets lots of questions. During  at the Air Force Association's annual symposium, Shotwell was thrown a question she said she had never heard before: "Would SpaceX launch military weapons?" "I've never been asked that question," Shotwell said somewhat surprised. Her response: "If it's for the defense of this country, yes, I think we would." The room packed with Air Force service members and military contractors burst into applause. They seemed impressed that SpaceX is one of the world's coolest companies and also...

There are plenty of challenges to putting people on Mars, whether you look at the rocket, the astronaut or the planet itself. New data from one of the many spacecraft at work around Mars confirm just how dangerous a round-trip human journey would be by measuring the amount of radiation an astronaut would experience. Cosmic radiation is made up of incredibly tiny particles moving incredibly fast, nearly at the speed of light — the sort of phenomenon a human body isn't very well equipped to withstand. That radiation travels across all of space, but Earth's atmosphere buffers us from the worst...

SpaceX announced on Monday night that its first moonshot passenger will be Yusaku Maezawa, a billionaire estimated by Forbes to be the 18th richest person in Japan. He'll be the first private passenger to visit the moon in the company's much hyped Big Falcon Rocket -- if the launch happens. "I choose to go to the moon!" said the 42-year-old Maezawa, who founded Japan's largest online fashion mall and is worth almost $3 billion. The announcement was made at the company's headquarters in Hawthorne, California. The launch is scheduled to happen in 2023. It's not the first time the...

Tesla is under investigation by the Justice Department, a company spokesperson confirmed Tuesday. In a statement to The Washington Times, the Tesla spokesperson said the Justice Department reached out for documents after an August tweet by CEO Elon Musk about taking the high-tech car company private:

Vernon Unsworth, the caver accused by Elon Musk of being a pedophile, filed a defamation lawsuit against the Tesla CEO on Monday.

Spacecraft and satellites could in future be launched into space without the need for fuel, thanks to a revolutionary new theory. Dr Mike McCulloch, from the University of Plymouth, first put forward the idea of quantised inertia (QI) – through which he believes light can be converted into thrust – in 2007. He has now received $1.3million from the United States Defense Advanced Research Projects Agency (DARPA) for a four-year study which aims to make the concept a reality. The QI theory predicts that objects can be pushed by differences in the intensity of so-called Unruh radiation in space, similar...

Establishing President Donald Trump's sought-after Space Force could cost $12.9 billion over its first five years, according to an Air Force document obtained by CNN. The Air Force estimates that the first year "additive costs" associated with establishing the new military branch in the 2020 fiscal year, including the creation of a headquarters, would amount to $3.32 billion. The document also estimates that the Space Force will oversee some 13,000 personnel when it is officially launched. In a memo accompanying the proposal, Air Force Secretary Heather Wilson calls on Congress to authorize and fund the establishment of a Space Force...

It's going to be a big night for space tourism. The private spaceflight company SpaceX will reveal its first passenger for a trip around the moon on the company's massive BFR rocket and you can watch it all live online. SpaceX CEO Elon Musk has even dropped tantalizing previews of the BFR's new rocket design on Twitter. SpaceX will unveil its BFR rocket passenger (the name stands for Big Falcon Rocket) in a webcast tonight (Sept. 17) at its Hawthorne, California headquarters. You can watch it live here, courtesy of SpaceX, beginning at 9 p.m. EDT (0100 Sept. 18 GMT)....

Elon Musk is no stranger to making headlines with his comments. But he might have just recorded one of his most quotable interviews ever. In a 2.5-hour candid interview with comedian Joe Rogan for "The Joe Rogan Experience", Musk talks about why we're likely living in a simulation, how flamethrowers are "a terrible idea", smokes a joint, calls The Boring Company a "hobby", and issues a stark warning against our use of coal and artificial intelligence. And that's just scratching the surface of the unwieldy but incredibly entertaining interview, which you can watch in full below. Musk's Matrix-style simulation hypothesis...

The display comes weeks after the country announced an ambitious timeline to launch its first crewed mission by 2022 in time to commemorate the 75th anniversary of the country's independence. The human-spaceflight program is called Gaganyaan and will build on the legacy of India's first astronaut, Rakesh Sharma, who flew in 1984. But this time, India is developing every aspect of the program, which means tackling problems like spacesuit design. The spacesuits, which have been in the works for two years, are each equipped with an oxygen cylinder that can support an astronaut for an hour, local reports added. The...

CNBC Mad Money host Jim Cramer on Tuesday suggested Tesla CEO Elon Musk take a medical leave of absence from the embattled electric car company, citing the embattled billionaire’s recent “self-destructive” behavior. “I’m worried about the guy,” Cramer told Squawk on the Street panelists. “Medical leave is fine. I think the board puts him on medical leave. That’s not a sin.” “A healthy Elon Musk is something that can take the stock higher,” he added.

Two coinciding culture points are flowing side-by-side to suggest an ongoing revolution in communications — one that could both dramatically change how Americans choose their communication channels while sharply undermining the influence of the mainstream media. Number one: We, driven by the media and our celebrity culture, have made American presidents out to be far more important in our daily lives than they really are, and certainly should be. Number two: The media, largely responsible for No. 1, is again late to see an ongoing revolution in the communications industry, just as it has consistently during the past 25 years....

Robots can develop prejudices like “racism and sexism” all on their own, a shocking new study has found. Artificial intelligence experts performed thousands of simulations on robot brains, revealing how they split off into groups and treat “outsiders” differently. Computer scientists and psychologists from Cardiff University and MIT teamed up to test how robots identify each other.

FULL TITLE: Now Elon Musk faces US Air Force investigation into his wild weed-smoking podcast because the drug-taking breaches SpaceX security clearance rules The US Air Force is looking into Elon Musk after he smoked marijuana during a wild, rambling two-and-a-half-hour podcast streamed live onto YouTube, it emerged on Friday. Marijuana use is prohibited for people with government security clearance, which Musk gained in 2015 when his company SpaceX started launching satellites for the Pentagon. The US Air Force told DailyMail.com a formal investigation is not underway at this time, but would not rule out that members of the department...

To make the roughly six-month one-way journey, Musk and his engineers have dreamed up a 347-foot-tall launch system called the Big Falcon Rocket, or BFR. The spacecraft is designed to have two fully reusable stages: a 19-story booster and a 16-story spaceship, which would fly on top of the booster and into into space. SpaceX employees are now building a prototype of the Big Falcon Spaceship at the Port of Los Angeles. Gwynne Shotwell, the company's president and COO, reportedly said Thursday that the spaceship may start small test-launches in late 2019. Several official graphics of the spaceship's internal structure...

Shares of electric car maker Tesla Inc. fell more than 6 percent early Friday after the CEO appeared to smoke marijuana during an interview and the company’s accounting chief left after a month on the job. CEO Elon Musk appeared on “The Joe Rogan Experience” overnight. About two hours into the podcast, which can be seen on YouTube, Musk inhales from what the host says is a combined marijuana-tobacco joint, which Rogan notes is legal. Rogan passes the joint to Musk, who also takes a sip of whiskey. Shortly after smoking, Musk looks at his phone and laughs, telling Rogan...

Tech entrepreneur Elon Musk has smoked marijuana live on the web during a podcast with comedian Joe Rogan. Mr Rogan offered his guest the drug, which is legal in California, as the pair discussed tech innovation and the public's perception of Mr Musk. "I mean, it's legal, right?" asked the Tesla founder, before taking a drag on the joint. Last month, Mr Musk said he was not "on weed" when he tweeted about plans to make Tesla a private firm. The business leader made the comments in an interview with the New York Times. He also told the newspaper he...
