    NASA’S Lunar Trailblazer Hitches Ride to the Moon to Map Water for Astronauts

    Lunar Trailblazer, an orbiter that shared a launch on Wednesday with the commercial Athena lander, will help scientists understand where the moon’s water is, and what form it takes.The moon is not bone dry, scientists now know. But how many drops of water will thirsty astronauts find? No one knows for sure.A robotic NASA spacecraft called Lunar Trailblazer, which launched Wednesday night from Kennedy Space Center in Florida, is aiming to provide a detailed map from orbit of the abundance, distribution and form of water across the moon.Lunar Trailblazer tagged along for the ride to space on the same SpaceX Falcon 9 rocket as Athena, a commercial lunar lander built by Intuitive Machines of Houston, which will deploy a NASA instrument to drill in the moon and sniff for water vapors.Athena will study one spot on the moon. Lunar Trailblazer will provide a global picture of water on the moon.“That’s another exciting thing for us as we get more science into space with one launch,” Nicola Fox, the associate administrator for NASA’s science mission directorate, said during a news conference before the launch.Less than an hour after liftoff, Lunar Trailblazer and Athena went their separate ways. Athena is taking a direct path to the moon, with landing scheduled for March 6, while Lunar Trailblazer set off on a meandering but fuel-efficient journey that will take four months to reach its destination. After it enters orbit, the spacecraft will make observations for at least two years.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Elon Musk Is Focused on DOGE. What About Tesla?

    Mr. Musk, one of President Trump’s main advisers, has not outlined a plan to reverse falling sales at the electric car company of which he is chief executive.Elon Musk’s role as President Trump’s cost-cutting czar and his immersion in right-wing politics appears to be diverting his attention from Tesla at a perilous moment for the electric car company.Tesla’s car sales fell 1 percent last year even as the global market for electric vehicles grew 25 percent. Mr. Musk has not addressed that underperformance, and he has offered no concrete plan to revive sales. He has also provided no details about a more affordable model Tesla says it will start producing this year. In the past, Mr. Musk spent months or years promoting vehicles before they appeared in showrooms.And he has spent much of his time since the election in Washington and at Mr. Trump’s home in Florida — far from Austin, Texas, where Tesla has its corporate headquarters and a factory, or the San Francisco Bay Area, where it has a factory and engineering offices.In the past decade or so, Tesla went from a struggling start-up to upending the global auto industry. The company sold millions of electric cars and generated huge profits, forcing established automakers to invest billions of dollars to catch up. Tesla’s success has been reflected in its soaring stock price, which helped make Mr. Musk the world’s richest person.But now, he seems to have lost interest in the grinding business of developing, producing and selling cars, investors and analysts say. That could have serious ramifications for his company and the auto industry, which employs millions of people worldwide.Even before he joined the Trump administration as the head of the Department of Government Efficiency, Mr. Musk’s running multiple companies had led investors and corporate governance experts to wonder whether he was spread too thin. Besides Tesla, Mr. Musk controls and runs SpaceX, whose rockets carry astronauts and satellites for NASA and others; X, the social media site; and xAI, which is developing artificial intelligence. And he wants to colonize Mars.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Elon Musk and Jeff Bezos Exchange Posts About Trump on X

    The world’s two richest men are longtime business rivals, but now one of them has the ear of the next president of the United States.A few months ago, a three-post exchange between Jeff Bezos and Elon Musk on Mr. Musk’s X would have passed for petty sniping between billionaire rivals.But times have changed.“Just learned tonight at Mar-a-Lago that Jeff Bezos was telling everyone that @realDonaldTrump would lose for sure, so they should sell all their Tesla and SpaceX stock,” Mr. Musk wrote Wednesday night, referring to two of his companies. He added an emoji for a snickering face, with a hand covering the mouth.“Nope. 100% not true,” Mr. Bezos responded on Thursday morning.“Well, then, I stand corrected,” Mr. Musk wrote back, with a laughing-crying emoji.With President-elect Donald J. Trump’s history of animosity toward Mr. Bezos, the posts carried an unspoken message about Mr. Musk’s growing power within the incoming administration.The exchange — brief, brassy and fairly typical of Mr. Musk’s overwhelming presence on X — could foreshadow a bumpy next few years for Mr. Bezos and the companies he started, Amazon and the rocket maker Blue Origin. It was also a reminder that the power dynamics in the longtime rivalry between the world’s two richest men changed on Nov. 5.Plenty of tech executives have drawn Mr. Trump’s wrath over the last few years. Perhaps none more than Mr. Bezos, largely because he owns The Washington Post, which has frequently written critically about Mr. Trump. (The Post did not endorse a presidential candidate this year, a decision that angered many of its readers and that Mr. Bezos publicly defended.)We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    California Rejects Bid for More Frequent SpaceX Launches

    A commission denied a request to increase the number of rocket launches on the state’s central coast, citing environmental concerns.A California state commission this week rejected the U.S. Space Force’s bid to increase the number of SpaceX rocket launches on the state’s central coast, citing concerns about the environmental impacts of the launches.The Space Force had sought to increase the number of launches of SpaceX’s flagship Falcon 9 rocket from 36 to 50 per year out of California. But on Thursday, the California Coastal Commission denied the bid in a 6-4 vote, pointing to its previous requests for the military and SpaceX to mitigate the disruptive sonic booms caused by the rockets and to keep a closer eye on the operations’ effects on the state’s wildlife.The commission also rejected the military and SpaceX’s argument that the launches should be considered a federal activity, saying they mostly benefit SpaceX and its private business operations, as opposed to the government.The move came just a couple of months after the commission had approved increasing the number of SpaceX launches to 36, contingent on the military’s commitment to adopting such measures. The board, which is tasked with protecting the state’s coastal resources, previously expressed its reservation for approving more launches without understanding the effects of the sonic booms and launch debris on wildlife.SpaceX, which is owned by Elon Musk, has grown to dominate the space launch business, serving as the primary provider to both NASA and the Pentagon. It has blasted its own commercial satellites into space out of bases across the country at a rapid clip, and it is set to test its new Starship rocket on Sunday in Texas. In California, SpaceX carries out many of its missions at the Vandenberg Space Force Base in Santa Barbara County.But the sonic booms have been startling residents in Southern California, whose homes have been shaken by powerful, confusing jolts, The Los Angeles Times reported. And several environmental groups submitted letters urging the commission to take more time to study the impact on wildlife ahead of this week’s meeting.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    F.A.A. Clears the Way for SpaceX to Hold Starship Launch on Sunday

    The agency said the company had agreed to study the environmental impact of its launches in South Texas and ways to mitigate harm to wildlife.The Federal Aviation Administration issued a new license on Saturday allowing Elon Musk’s SpaceX company to launch its Starship rocket again from South Texas, and it included new requirements to limit the harm to birds’ nests and other wildlife in an adjacent state park and National Wildlife Refuge.The action by the F.A.A., which came after weeks of pressure by Mr. Musk on the agency to speed up its latest review, allows Mr. Musk to go ahead with his next test of Starship, with a launch now set to take place as early as 8 a.m. Eastern time on Sunday.So far, SpaceX has been required to obtain a license for each launch. With the latest license, the F.A.A. is allowing the company to launch more than once, unless it modifies its procedures.Starship, the largest rocket ever built, has not yet carried any humans into space, as its reliability is still being assessed. But this is the spaceship that Mr. Musk is under contract to use to land NASA astronauts on the moon — and that he hopes to someday use to take humans to Mars.But as prototypes and full-scale versions of the rocket have been tested at the company’s launch site at the edge of the Gulf of Mexico near the Mexican border in South Texas, there has been widespread evidence of environmental consequences to the region, as detailed in a New York Times investigation in July.The report in The Times examined, in part, damage that a Starship launch in June caused to the fragile migratory bird habitat surrounding the launch site, including destroying eggs in nearby nests.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    SpaceX to Launch Crew-9 Mission for NASA: How to Watch

    Two astronauts — one American, one Russian — will launch on a flight that is set to bring the Boeing Starliner astronauts home next year.Eight times during the past four years, SpaceX has provided a regular astronaut transportation service for NASA from Kennedy Space Center in Florida.Its next flight to the International Space Station, scheduled to launch on Saturday, will not be like the previous eight.There will be two, not four, astronauts aboard. Two other astronauts who were assigned to the mission will remain on Earth. And the mission, named Crew-9, will launch from a different launchpad.The shuffling is a consequence of difficulties with a different spacecraft, Boeing’s Starliner, over the summer.“The word that comes to mind for this flight is ‘agility,’” Steve Stich, the manager for NASA’s commercial crew program, said during a prelaunch news conference on Friday.Here’s what you need to know about Saturday’s launch, and why it’s unlike other recent NASA astronaut missions.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    SpaceX Polaris Dawn Spacewalk: How to Watch the Astronauts

    The astronauts of the Polaris Dawn mission, after traveling through heavy radiation and high orbits, are getting ready to open the hatch of their SpaceX vehicle.Early Thursday morning, four private astronauts circling far above Earth will try something daring — let all the air out of their spacecraft.That will be a prelude for two of the astronauts, who will then venture outside for the first commercial spacewalk ever, an event that is to be the highlight of the Polaris Dawn mission led by Jared Isaacman, a billionaire entrepreneur.When is the spacewalk and how can I watch it?The spacewalk is scheduled to begin at 2:23 a.m. Eastern time. SpaceX plans to broadcast live coverage starting one hour before the spacewalk begins.If needed, a backup opportunity is available on Friday at the same time.What will happen during the spacewalk?Because there is no airlock in the SpaceX Crew Dragon spacecraft used for the flight, the only way to perform a spacewalk is to let all the air out of the spacecraft, and then open one of the hatches. That requires all four crew members to wear spacesuits.NASA and Soviet astronauts conducted spacewalks in a similar manner in the 1960s.As the Crew Dragon swings around Earth in an elliptical orbit that swings as close as 120 miles to the surface and as high as 460 miles, Mr. Isaacman and Sarah Gillis, a SpaceX engineer, will exit the capsule for about 15 to 20 minutes each.They will pass through the hatch at the top of the Crew Dragon with the help of a handrail that SpaceX has named Skywalker, moving around carefully and deliberately. The two will not be outside the spacecraft at the same time.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Polaris Dawn Astronauts in SpaceX Dragon Reach Record Orbit Above Earth

    After launching early on Tuesday, the billionaire Jared Isaacman and his crew traveled to altitudes not visited by any astronaut since the Apollo moon missions of the 1960s and ’70s.Four private astronauts aboard an ambitious space mission led by a billionaire entrepreneur traveled farther from Earth on Tuesday than any other human being in more than half a century.Two of them, Sarah Gillis and Anna Menon, have now gone farther from the planet than any other women ever.The mission, named Polaris Dawn, lifted off through a break of favorable weather before sunrise on Tuesday. The flight had been grounded for nearly two weeks by unsettled weather in and around Florida.The astronauts, flying an elliptical path around Earth in a SpaceX Crew Dragon capsule, looped outward as far out as 755 miles above the planet’s surface. The mission’s orbits were carefully planned to reduce the hit of radiation the crew would absorb, and to minimize the chances of being struck by tiny bits of rock crisscrossing the solar system.The journey on Tuesday was only a small fraction of the nearly quarter million miles that NASA’s Apollo astronauts traveled to the moon. But after the last mission going there in 1972, humanity has stayed close to our planet, not venturing beyond orbits a few hundred miles up.The Polaris Dawn mission, led by Jared Isaacman, founder of the payment services company Shift4, is a collaboration with SpaceX, the rocket company founded by Elon Musk. It is the first of three missions designed to spur technological advances needed for Mr. Musk’s ambition to send people to Mars eventually.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
