Best of MWC: Screens that roll, ChatGPT interactive glasses
BARCELONA, Mar 3 (AP/UNB) — The father of the cellphone was there. So was Huawei and a host of other Chinese tech companies. Tens of thousands of visitors also flocked to the MWC tech fair to be dazzled by the latest advances in AI, smartphones, robotics and much more.
The metaverse got a lot of attention at the show, also known as Mobile World Congress, as companies cash in on the hype surrounding new virtual worlds for work and play.
SK Telecom’s virtual reality air taxi flight simulator was one of the most popular demonstrations, with long lines to take a virtual ride. There were robot dogs to remotely inspect infrastructure and holograms for virtual learning, along with speeches from wireless industry executives and backroom schmoozing with government officials.
Some 80,000 people were expected to attend the world’s biggest wireless trade show, which wraps up its four-day run in Barcelona on Thursday.
Here’s a look at some highlights:
SCROLL AND FOLD
While MWC smartphone launches don’t get as much attention as they used to because innovations have slowed, devices with nifty screens took the spotlight.
Motorola added the wow factor by unveiling a phone with a screen that rolls out. Double tap your fingers on the side, and the display automatically extends from 5 inches long (13 centimeters) to 6.5 inches by unscrolling from the bottom.
Motorola’s owner, Chinese tech brand Lenovo, also showed off a laptop with a rolling screen, which took about 19 seconds to unscroll to its fully extended position. The company said they’re concept devices and unlikely to hit the market anytime soon.
Other brands including Samsung and China’s Oppo and Tecno also released their latest folding designs.
Phones with foldable screens have drawn attention from consumers, but “whether that interest then translates into sales is a different question,” said Gerrit Schneemann, senior analyst at GfK Boutique. “For the next few years, I think they’ll still be a real niche market in the overall smartphone market. Growing, but still — relatively speaking — relatively small.”
AI CHAT GLASSES
Artificially intelligent chatbots like ChatGPT have taken the tech world by storm, and U.K. startup XRAI Glass is joining the fray with augmented reality glasses.
The company’s virtual assistant app was designed to work with smart viewer glasses to help people who are deaf or hard of hearing better understand what’s happening around them. Speech is transcribed from other people nearby and the subtitles are displayed onto the lenses or an attached smartphone.
Now XRAI (pronounced X-ray) has integrated OpenAI’s ChatGPT technology into its app and glasses setup.
“People can ask questions such as general knowledge or recipes or anything they like,” CEO Dan Scarfe said. “Or they can actually ask questions of their conversation. So, ‘Hey, XRAI, can you please summarize this conversation?’ Or, ‘Hey, XRAI, what was the name of the town that we were just talking about?’”
For those with hearing loss, it can be helpful to have an AI assistant recap a conversation in which multiple people were talking, the company says.
DIGITAL HUMANS
People might feel better interacting with AI chatbots if they had human faces. That’s the thinking at D-ID, an Israeli startup, which launched a new interface for its “digital human” — essentially an online avatar that can work with AI-chat systems to hold conversations.
“We had the chatbot in the past. They didn’t work,” said CEO Gil Perry, because they could only answer specific questions with specific answers. Now, “large language models are bringing huge improvements to traditional chatbots.”
Generative AI systems like ChatGPT can create readable text and hold conversations based on what they’ve learned from so-called large language models — vast databases of digital books, online writings and other media.
Perry demonstrated by asking a question to the chatbot’s face on his laptop, whose response was eerily lifelike. He said safeguards would prevent D-ID’s technology from being used maliciously.
“The idea here is not to replace anyone and not to convince anyone that what they’re seeing is true,” Perry said. It’s just that humans are “used to communicating with faces.”
REMOTE CONTROL CARS
At German mobility startup Vay’s display, a driver was steering a car around a course marked with pylons. But the car was 1,800 kilometers (1,118 miles) away in Berlin.
The company’s technology enables cars to be driven by remote “tele-drivers.” So far, so standard.
The twist is in Vay’s business model, which is a cross between taxi service and car rental. When a user hails a ride, a tele-driver will steer one of its electric cars to the pickup point for the customer, who will take over the driving duties. At the destination, the car will be taken away by a remote driver. No need to park.
The company says it’s the first in Europe to be allowed to operate cars on public streets without a human driver inside. It has 20 certified tele-drivers so far and plans to launch the service soon in Germany and the U.S.
“We’re talking, you know, hopefully months,” CEO Thomas von der Ohe said.
One of the main goals is to rid city streets of cars that are parked and not used for most of the day.
The service will be “a big step to start creating an alternative so people don’t buy the second car or the third car maybe in the near future,” von der Ohe said. “Also not the first car. ”
AUGMENTED REALITY EXPERIENCES
Software company Amdocs demonstrated AR technology that could be used for “next-generation immersive experiences” for both fans and security staff at big-ticket sports games.
For example, soccer fans attending a match in person could buy a package of extras for their AR glasses, including exclusive replay videos and live stats shown on their lenses to “augment” their game experience.
The same glasses also could be used as an extra tool for security staff at the game, with additional safety features including a security database.
In a simulation at MWC, guards were alerted to rowdy fans trying to climb the gates. A known soccer hooligan was flagged on the database, his face and details flashing up on the lenses.
Users, viewing the scene from the guard’s perspective, scanned the crowd as the glasses picked out faces before identifying the suspect so he could be apprehended — an unsettling display bordering on Orwellian.
Barcelona Mobile World Congress: Telecom giants display future of 5G revolution
A demonstration on how the use of 5G will make it possible to secure high-risk industrial management in the future has been exhibited at the ongoing Mobile World Congress in Barcelona, Spain.
King Felipe of Spain on Monday inaugurated the four-day conference of all the telecom companies of the world. Some 80,000 delegates are expected at the annual gathering of the big players of the telecom industry.
At the Mobile World Congress, many tech manufacturers are announcing 5G technology for virtual interactive applications, robot clusters, automated driving, smart wearables, automated patrol inspections, smart mining, smart tunneling, and other applications in coal mining.
The 5G has been the centre of attention at this year’s congress. The industry giants have been demonstrating the necessary use of 5G technologies not only in industrial production but also in people’s lives. The demonstrations of 5 G-powered devices include, among others, unmanned helicopters and routers.
T-Mobile is exhibiting unmanned helicopters. This helicopter can take off and land safely with passengers without a pilot. The helicopter can even make an emergency landing by choosing the nearest safe place if it detects any adverse conditions while flying in the sky. The 5G router will be completely different from the current routers.
Meanwhile, the 5G technology will completely overhaul the routers we see today. The 5G-powered wireless routers will only connect to the network through a code from a specific operator. And with the bandwidth that this router will have, it will be possible to keep all kinds of smart devices in the family connected to high-speed Internet.
Father of cellphone sees dark side but also hope in new tech
The man credited with inventing the cellphone 50 years ago had only one concern then about the brick-sized device with a long antenna: Would it work?
These days Martin Cooper frets like everybody else about his invention’s impacts on society — from the loss of privacy to the risk of internet addiction to the rapid spread of harmful content, especially among kids.
“My most negative opinion is we don’t have any privacy anymore because everything about us is now recorded someplace and accessible to somebody who has enough intense desire to get it,” said Cooper, who spoke with The Associated Press at the telecom industry’s biggest trade show in Barcelona, where he was receiving a lifetime award.
Yet the 94-year-old self-described dreamer also marvels at how far cellphone design and capabilities have advanced, and he believes the technology’s best days may still be ahead of it in areas such as education and health care.
“Between the cellphone and medical technology and the Internet, we are going to conquer disease,” he said Monday at MWC, or Mobile World Congress.
Cooper, whose invention was inspired by Dick Tracy's radio wristwatch, said he also envisions a future in which cellphones are charged by human bodies.
It’s a long way from where he started.
Also Read: Mobile World Congress kicks off in Barcelona
Cooper made the first public call from a handheld portable telephone on a New York City street on April 3, 1973, using a prototype that his team at Motorola had started designing only five months earlier.
To needle the competition, Cooper used the Dyna-TAC prototype — which weighed 2.5 pounds and was 11 inches long — to call to his rival at Bell Labs, owned by AT&T.
“The only thing that I was worried about: ‘Is this thing going to work?’ And it did,” he said.
The call helped kick-start the cellphone revolution, but looking back on that day Cooper acknowledges, “we had no way of knowing this was the historic moment.”
He spent the better part of the next decade working to bring a commercial version of the device to market, helping to launch the wireless communications industry and, with it, a global revolution in how we communicate, shop and learn about the world.
Still, Cooper said he’s “not crazy” about the shape of modern smartphones, blocks of plastic, metal and glass. He thinks phones will evolve so that they will be “distributed on your body,” perhaps as sensors “measuring your health at all times.”
Batteries could even be replaced by human energy.
“You ingest food, you create energy. Why not have this receiver for your ear embedded under your skin, powered by your body?” he imagined.
While he dreams about what the future might look like, Cooper is attuned to the industry's current challenges, particularly around privacy.
In Europe, where there are strict data privacy rules, regulators are concerned about apps and digital ads that track user activity, allowing technology and other companies to build up rich profiles of users.
“It’s going to get resolved, but not easily,” Cooper said. “There are people now that can justify measuring where you are, where you’re making your phone calls, who you’re calling, what you access on the Internet.”
Smartphone use by children is another area that needs limits, Cooper said. One idea is to have “various internets curated for different audiences.”
Five-year-olds should be able to use the internet to help them learn, but “we don’t want them to have access to pornography and to things that they don’t understand,” he said.
As for his own phone use, Cooper says he checks email and does online searches for information to settle dinner table arguments.
However, “there are many things that I have not yet learned,” he said. “I still don’t know what TikTok is.”
Mobile World Congress kicks off in Barcelona
King Felipe VI of Spain on Monday inaugurated the Mobile World Congress (MWC)-2023, an annual get-together of the big players of the telecom industry.
Some 80,000 delegates are expected at the four-day get-together of all the industrial titans, which is back to near full strength following years of pandemic-related disruption.
The Spanish King inaugurated the congress in front of about one and a half million people in Barcelona. The country’s president Prado Sanchez also attended the opening ceremony.
One of the aspects of this year’s event is the addition of ‘Velocity’, the outline of an upcoming smart world. Velocity is a global initiative by the telecom industries around the world which is the centre of focus in this year’s Mobile World Congress (MWC).
According to the velocity initiative, nearly one billion people will be connected to the 5G network by the end of 2023. Countries around the world are expected to come under smart technologies from next year.
The initiative was taken to ensure that no country is left behind on the way forward to digital transformation.
In a world divided by culture, ethnicity, and language, the velocity initiative also aims to bridge the gap among the people around the world.
Hundreds of thousands of tech enthusiasts from more than 200 countries attended the opening ceremony of the event. At the ceremony, King Felipe called on everyone to ensure the humane use of technology for the future.
“We will go further with technology. However, innovators and service providers need to be aware that their technology doesn't dehumanize people and turn them into heartless machines,” he said.
The telecom industry giants have pledged to be at the forefront of the "tsunami of innovation."
"We are at the doors of a new change of era driven by the intersection of Telco, Computing, Artificial Intelligence and Web3," said Jose Maria Alvarez-Pallete, boss of Spanish operator Telefonica and current chairman of industry body GSMA, which organizes the Barcelona event.
He promised the telecoms industry would be at the forefront of the "tsunami of innovation", adding: "Without telcos there is no digital future."
GSMA Chairman said, the purpose of this year's Mobile World Congress is a little different than before, which is reflected in the main theme. This year's main theme is to ensure the use of information technology to build a world free from poverty
This year's Mobile World Congress has the exhibition center of ten thousand companies from almost two hundred countries. Industrial titans like Huawei, Nokia and Samsung are set to showcase their latest innovations, flanked by smartphone makers like Oppo and Xiaomi and network operators like Orange, Verizon, and China Mobile.
The world is now gripped by a fear that the machine is leading to the destruction of human civilization. Tech giants from around the world said they are working on humanizing the machines. They’re also showing people how technology is changing people's lives and the pattern of work.
According to the innovators attending the conference, it is now necessary for people to learn about new technologies. Technology will not replace people’s jobs, rather it will make their work easier, they said.
US scientists set to announce fusion energy breakthrough
Energy Secretary Jennifer Granholm was set to announce a “major scientific breakthrough” Tuesday in the decades-long quest to harness fusion, the energy that powers the sun and stars.
Researchers at the Lawrence Livermore National Laboratory in California for the first time produced more energy in a fusion reaction than was used to ignite it, something called net energy gain, according to one government official and one scientist familiar with the research. Both spoke on the condition of anonymity because they were not authorized to discuss the breakthrough ahead of the announcement.
Granholm was scheduled to appear alongside Livermore researchers at a morning event in Washington. The Department of Energy declined to give details ahead of time. The news was first reported by the Financial Times.

Proponents of fusion hope that it could one day produce nearly limitless, carbon-free energy, displacing fossil fuels and other traditional energy sources. Producing energy that powers homes and businesses from fusion is still decades away. But researchers said it was a significant step nonetheless.
“It’s almost like it’s a starting gun going off,” said Professor Dennis Whyte, director of the Plasma Science and Fusion Center at the Massachusetts Institute of Technology and a leader in fusion research. “We should be pushing towards making fusion energy systems available to tackle climate change and energy security.”
Net energy gain has been an elusive goal because fusion happens at such high temperatures and pressures that it is incredibly difficult to control.
Fusion works by pressing hydrogen atoms into each other with such force that they combine into helium, releasing enormous amounts of energy and heat. Unlike other nuclear reactions, it doesn’t create radioactive waste.
Billions of dollars and decades of work have gone into fusion research that has produced exhilarating results — for fractions of a second. Previously, researchers at the National Ignition Facility, the division of Lawrence Livermore where the success took place, used 192 lasers and temperatures multiple times hotter than the center of the sun to create an extremely brief fusion reaction.
The lasers focus an enormous amount of heat on a small metal can. The result is a superheated plasma environment where fusion may occur.

Riccardo Betti, a professor at the University of Rochester and expert in laser fusion, said an announcement that net energy had been gained in a fusion reaction would be significant. But he said there’s a long road ahead before the result generates sustainable electricity.
He likened the breakthrough to when humans first learned that refining oil into gasoline and igniting it could produce an explosion.
“You still don’t have the engine and you still don’t have the tires,” Betti said. “You can’t say that you have a car.”
The net energy gain achievement applied to the fusion reaction itself, not the total amount of power it took to operate the lasers and run the project. For fusion to be viable, it will need to produce significantly more power and for longer.
It is incredibly difficult to control the physics of stars. Whyte said it has been challenging to reach this point because the fuel has to be hotter than the center of the sun. The fuel does not want to stay hot -- it wants to leak out and get cold. Containing it is an incredible challenge, he said.
Net energy gain isn’t a huge surprise from the California lab because of progress it had already made, according to Jeremy Chittenden, a professor at Imperial College in London specializing in plasma physics.
“That doesn’t take away from the fact that this is a significant milestone,” he said.
It takes enormous resources and effort to advance fusion research. One approach turns hydrogen into plasma, an electrically charged gas, which is then controlled by humongous magnets. This method is being explored in France in a collaboration among 35 countries called the International Thermonuclear Experimental Reactor as well as by researchers at the Massachusetts Institute of Technology and a private company.
Last year the teams working on those projects in two continents announced significant advancements in the vital magnets needed for their work.
NASA’s newest moon rocket lifts off 50 years after Apollo
NASA’s new moon rocket blasted off on its debut flight with three test dummies aboard early Wednesday, bringing the U.S. a big step closer to putting astronauts back on the lunar surface for the first time since the end of the Apollo program 50 years ago.
If all goes well during the three-week, make-or-break shakedown flight, the rocket will propel an empty crew capsule into a wide orbit around the moon, and then the capsule will return to Earth with a splashdown in the Pacific in December.
After years of delays and billions in cost overruns, the Space Launch System rocket thundered skyward, rising from Kennedy Space Center on 8.8 million pounds (4 million kilograms) of thrust and hitting 100 mph (160 kph) within seconds. The Orion capsule was perched on top, ready to bust out of Earth orbit toward the moon not quite two hours into the flight.
The moonshot follows nearly three months of vexing fuel leaks that kept the rocket bouncing between its hangar and the pad. Forced back indoors by Hurricane Ian at the end of September, the rocket stood its ground outside as Nicole swept through last week with gusts of more than 80 mph (130 kph). Although the wind peeled away a 10-foot (3-meter) strip of caulking high up near the capsule, managers gave the green light for the launch.
NASA expected 15,000 to jam the launch site, with thousands more lining the beaches and roads outside the gates, to witness NASA’s long-awaited sequel to Project Apollo, when 12 astronauts walked on the moon from 1969 and 1972. Crowds also gathered outside NASA centers in Houston and Huntsville, Alabama, to watch the spectacle on giant screens.
Cheers accompanied the rocket as it rode a huge trail of flame toward space, with a half-moon glowing brightly and buildings shaking as though hit by a major quake.
“For the Artemis generation, this is for you,” launch director Charlie Blackwell-Thompson called out, referring to all those born after Apollo.
The liftoff marked the start of NASA’s Artemis lunar-exploration program, named after Apollo’s mythological twin sister. The space agency is aiming to send four astronauts around the moon on the next flight, in 2024, and land humans there as early as 2025.
“You have earned your place in history,” Blackwell-Thompson told her team following liftoff. “You’re part of a first. Doesn’t come along very often. Once in a career maybe. But we are all part of something incredibly special: the first launch of Artemis. The first step in returning our country to the moon and on to Mars.”
The 322-foot (98-meter) SLS is the most powerful rocket ever built by NASA, with more thrust than either the space shuttle or the mighty Saturn V that carried men to the moon. A series of hydrogen fuel leaks plagued the summertime launch attempts as well as countdown tests. A fresh leak erupted at a new location during Tuesday night’s fueling, but an emergency team managed to tighten the faulty valve on the pad. Then a U.S. Space Force radar station went down, resulting in another scramble, this time to replace an ethernet switch.
Orion should reach the moon by Monday, more than 230,000 miles (370,000 kilometers) from Earth. After coming within 80 miles (130 kilometers) of the moon, the capsule will enter a far-flung orbit stretching about 40,000 miles (64,000 kilometers) beyond.
The $4.1 billion test flight is set to last 25 days, roughly the same as when crews will be aboard. The space agency intends to push the spacecraft to its limits and uncover any problems before astronauts strap in. The mannequins — NASA calls them moonequins — are fitted with sensors to measure such things as vibration, acceleration and cosmic radiation.
“There’s a fair amount of risk with this particular initial flight test,” said mission manager Mike Sarafin.
The rocket was supposed to have made its dry run by 2017. Government watchdogs estimate NASA will have spent $93 billion on the project by 2025.
Ultimately, NASA hopes to establish a base on the moon and send astronauts to Mars by the late 2030s or early 2040s.
But many hurdles still need to be cleared. The Orion capsule will take astronauts only to lunar orbit, not the surface.
NASA has hired Elon Musk’s SpaceX to develop Starship, the 21st-century answer to Apollo’s lunar lander. Starship will carry astronauts back and forth between Orion and the lunar surface, at least on the first trip in 2025. The plan is to station Starship and eventually other companies’ landers in orbit around the moon, ready for use whenever new Orion crews pull up.
Reprising an argument that was made during the 1960s, Duke University historian Alex Roland questions the value of human spaceflight, saying robots and remote-controlled spacecraft could get the job done more cheaply, efficiently and safely.
“In all these years, no evidence has emerged to justify the investment we have made in human spaceflight — save the prestige involved in this conspicuous consumption,” he said.
NASA is waiting until this test flight is over before introducing the astronauts who will be on the next one and those who will follow in the bootsteps of Apollo 11′s Neil Armstrong and Buzz Aldrin.
Most of NASA’s corps of 42 active astronauts and 10 trainees were not even born yet when Apollo 17 moonwalkers Gene Cernan and Harrison Schmitt closed out the era, 50 years ago next month.
“We are jumping out of our spacesuits with excitement,” astronaut Christina Koch said Tuesday.
After a nearly yearlong space station mission and all-female spacewalk, Koch, 43, is on NASA’s short list for a lunar flight. So is astronaut Kayla Barron, 35, who finally got to witness her first rocket launch, not counting her own a year ago.
“It took my breath away, and I was tearing up,” Barron said. “What an amazing acccomplishment for this team.”
NASA spacecraft rams into asteroid in defence test
A NASA spacecraft rammed an asteroid at blistering speed Monday in an unprecedented dress rehearsal for the day a killer rock menaces Earth.
The galactic slam occurred at a harmless asteroid 7 million miles (11.3 million kilometers) away, with the spacecraft named Dart plowing into the space rock at 14,000 mph (22,500 kph). Scientists expected the impact to carve out a crater, hurl streams of rocks and dirt into space and, most importantly, alter the asteroid’s orbit.
“We have impact!” Mission Control's Elena Adams announced, jumping up and down and thrusting her arms skyward.
Telescopes around the world and in space aimed at the same point in the sky to capture the spectacle. Though the impact was immediately obvious — Dart’s radio signal abruptly ceased — it will take as long as a couple of months to determine how much the asteroid’s path was changed.
The $325 million mission was the first attempt to shift the position of an asteroid or any other natural object in space.
“As far as we can tell, our first planetary defense test was a success,” Adams later told a news conference, the room filling with applause. “I think Earthlings should sleep better. Definitely, I will.”
NASA Administrator Bill Nelson reminded people earlier in the day via Twitter that, “No, this is not a movie plot.” He added in a prerecorded video: ”We’ve all seen it on movies like ‘Armageddon,’ but the real-life stakes are high."
Monday’s target: a 525-foot (160-meter) asteroid named Dimorphos. It’s a moonlet of Didymos, Greek for twin, a fast-spinning asteroid five times bigger that flung off the material that formed the junior partner.
The pair have been orbiting the sun for eons without threatening Earth, making them ideal save-the-world test candidates.
Launched last November, the vending machine-size Dart — short for Double Asteroid Redirection Test — navigated to its target using new technology developed by Johns Hopkins University’s Applied Physics Laboratory, the spacecraft builder and mission manager.
Dart’s on-board camera, a key part of this smart navigation system, caught sight of Dimorphos barely an hour before impact. “Woo hoo!” exclaimed Adams, a mission systems engineer at Johns Hopkins.
With an image beaming back to Earth every second, Adams and other ground controllers in Laurel, Maryland, watched with growing excitement as Dimorphos loomed larger and larger in the field of view alongside its bigger companion. Within minutes, Dimorphos was alone in the pictures; it looked like a giant gray lemon, but with boulders and rubble on the surface. The last image froze on the screen as the radio transmission ended.
Flight controllers cheered, hugged one another and exchanged high fives. Their mission complete, the Dart team went straight into celebration mode. There was little sorrow over the spacecraft's demise.
“Normally, losing signal from a spacecraft is a very bad thing. But in this case, it was the ideal outcome,” said NASA program scientist Tom Statler.
Johns Hopkins scientist Carolyn Ernst said the spacecraft was definitely “kaput," with remnants possibly in the fresh crater or cascading into space with the asteroid's ejected material.
Scientists insisted Dart would not shatter Dimorphos. The spacecraft packed a scant 1,260 pounds (570 kilograms), compared with the asteroid’s 11 billion pounds (5 billion kilograms). But that should be plenty to shrink its 11-hour, 55-minute orbit around Didymos.
The impact should pare 10 minutes off that. The anticipated orbital shift of 1% might not sound like much, scientists noted. But they stressed it would amount to a significant change over years.
“Now is when the science starts,” said NASA’s Lori Glaze, planetary science division director. “Now we’re going to see for real how effective we were.”
Planetary defense experts prefer nudging a threatening asteroid or comet out of the way, given enough lead time, rather than blowing it up and creating multiple pieces that could rain down on Earth. Multiple impactors might be needed for big space rocks or a combination of impactors and so-called gravity tractors, not-yet-invented devices that would use their own gravity to pull an asteroid into a safer orbit.
“The dinosaurs didn’t have a space program to help them know what was coming, but we do,” NASA’s senior climate adviser Katherine Calvin said, referring to the mass extinction 66 million years ago believed to have been caused by a major asteroid impact, volcanic eruptions or both.
The non-profit B612 Foundation, dedicated to protecting Earth from asteroid strikes, has been pushing for impact tests like Dart since its founding by astronauts and physicists 20 years ago. Monday’s feat aside, the world must do a better job of identifying the countless space rocks lurking out there, warned the foundation’s executive director, Ed Lu, a former astronaut.
Significantly less than half of the estimated 25,000 near-Earth objects in the deadly 460-foot (140-meter) range have been discovered, according to NASA. And fewer than 1% of the millions of smaller asteroids, capable of widespread injuries, are known.
The Vera Rubin Observatory, nearing completion in Chile by the National Science Foundation and U.S. Energy Department, promises to revolutionize the field of asteroid discovery, Lu noted.
Finding and tracking asteroids, “That’s still the name of the game here. That’s the thing that has to happen in order to protect the Earth,” he said.
Leak ruins NASA moon rocket launch bid; next try weeks away
NASA’s new moon rocket sprang another dangerous fuel leak Saturday, forcing launch controllers to call off their second attempt this week to send a crew capsule into lunar orbit with test dummies. The inaugural flight is now off for weeks, if not months.
The previous try on Monday at launching the 322-foot (98-meter) Space Launch System rocket, the most powerful ever built by NASA, was also troubled by hydrogen leaks, though they were smaller. That was on top of leaks detected during countdown drills earlier in the year.
After the latest setback, mission managers decided to haul the rocket off the pad and into the hangar for further repairs and system updates. Some of the work and testing may be performed at the pad before the rocket is moved. Either way, several weeks of work will be needed, according to officials.
With a two-week launch blackout period looming in just a few days, the rocket is now grounded until late September or October. NASA will work around a high-priority SpaceX astronaut flight to the International Space Station scheduled for early October.
Read: Fuel leak ruins NASA's 2nd shot at launching moon rocket
NASA Administrator Bill Nelson stressed that safety is the top priority, especially on a test flight like this where everyone wants to verify the rocket's systems “before we put four humans up on the top of it.”
"Just remember: We’re not going to launch until it’s right," he said.
NASA already has been waiting years to send the crew capsule atop the rocket around the moon. If the six-week demo succeeds, astronauts could fly around the moon in 2024 and land on it in 2025. People last walked on the moon 50 years ago.
Launch director Charlie Blackwell-Thompson and her team had barely started loading nearly 1 million gallons of fuel into the Space Launch System rocket at daybreak when the large leak cropped up in the engine section at the bottom.
Ground controllers tried to plug it the way they handled previous, smaller leaks: stopping and restarting the flow of super-cold liquid hydrogen in hopes of closing the gap around a seal in the supply line. They tried that twice, in fact, and also flushed helium through the line. But the leak persisted.
Blackwell-Thompson finally halted the countdown after three to four hours of futile efforts.
Mission manager Mike Sarafin told journalists it was too early to tell what caused the leak, but it may have been due to inadvertent over-pressurization of the hydrogen line earlier in the morning when someone sent commands to the wrong valve.
Read: NASA aims for Saturday launch of new moon rocket after fixes
“This was not a manageable leak,” Sarafin said, adding that the escaping hydrogen exceeded flammability limits by two or three times.
During Monday's attempt, a series of small hydrogen leaks popped up there and elsewhere on the rocket. Technicians tightened up the fittings over the following days, but Blackwell-Thompson had cautioned that she wouldn't know whether everything was tight until Saturday's fueling.
Hydrogen molecules are exceedingly small — the smallest in existence — and even the tiniest gap or crevice can provide a way out. NASA's space shuttles, now retired, were plagued by hydrogen leaks. The new moon rocket uses the same type of main engines.
Even more of a problem Monday was that a sensor indicated one of the rocket's four engines was too warm, though engineers later verified it actually was cool enough. The launch team planned to ignore the faulty sensor this time around and rely on other instruments to ensure each main engine was properly chilled. But the countdown never got that far.
Thousands of people who jammed the coast over the long Labor Day weekend, hoping to see the Space Launch System rocket soar, left disappointed.
The $4.1 billion test flight is the first step in NASA's Artemis program of renewed lunar exploration, named after the twin sister of Apollo in Greek mythology.
Years behind schedule and billions over budget, Artemis aims to establish a sustained human presence on the moon, with crews eventually spending weeks at a time there. It’s considered a training ground for Mars.
Twelve astronauts walked on the moon during the Apollo program, the last time in 1972.
Fuel leak interrupts launch countdown of NASA moon rocket
A fuel leak interrupted NASA's launch countdown for its new moon rocket early Monday, reappearing in the same place that saw seepage during a dress rehearsal back in the spring.
Launch controllers halted the tanking operation, which already was running an hour late because of thunderstorms offshore. They slowly resumed the process to confirm that it was, indeed, a hydrogen fuel leak and not faulty sensors, but alarms forced another temporary pause as precious minutes in the countdown ticked away.
The 322-foot (98-meter) rocket is the most powerful ever built my NASA, out-muscling even the Saturn V that carried astronauts to the moon a half-century ago.
This test flight, if successful, would put a crew capsule into lunar orbit for the first time in 50 years.
No astronauts were inside the Orion capsule atop the rocket at NASA's Kennedy Space Center. Instead, three test dummies were strapped in for the lunar-orbiting mission, expected to last six weeks.
Even with no one on board, thousands of people jammed the coast to see the Space Launch System, or SLS, rocket soar. Vice President Kamala Harris flew into Orlando with her husband, but had yet to make the hourlong drive to Cape Canaveral for the planned liftoff.
The next launch attempt wouldn’t be until Friday at the earliest.

Hydrogen fuel leaks marred NASA's countdown test back in April, prompting a slew of repairs. The demo was repeated with more success in June, but that, too, experienced some leakage. Managers said they would not know for certain whether the fixes were good until attempting to load the rocket's tanks with nearly 1 million gallons of super-cold fuel on Monday.
Launch director Charlie Blackwell-Thompson and her team also had to deal with a communication issue involving the Orion capsule.
Engineers scrambled to understand an 11-minute delay in the communication lines between Launch Control and Orion that cropped up late Sunday. Although the problem had cleared by Monday morning, NASA needed to know why it occurred before committing to launch.
This first flight of NASA's 21st-century moon-exploration program, named Artemis after Apollo's mythological twin sister, is years overdue. Repeated delays have led to billions in budget overruns; this demo alone costs $4.1 billion.
Assuming the test goes well, astronauts would climb aboard for the second flight and fly around the moon and back as soon as 2024. A two-person lunar landing could follow by the end of 2025. NASA is targeting the moon's south pole.
During Apollo, 12 astronauts landed on the moon from 1969 through 1972, with stays of no more than a few days. NASA is looking to establish a lunar base during Artemis, with astronauts rotating in and out for weeks at a time. The next step would be Mars, possibly in the late 2030s or early 2040s.
