      Earth Safe From Asteroid 2024 YR4, NASA Says

      by

      The odds that the space rock, 2024 YR4, will smash into our planet in 2032 have dropped to nearly zero, leading astronomers to conclude that we are no longer in danger.A NASA video showing the shifting odds that Asteroid 2024 YR4 would crash into Earth.Graphics by Nasa Jpl/cneosAstronomers have been carefully watching 2024 YR4, a space rock with a heightened chance of hitting Earth in 2032. But fear not: NASA announced on Monday that it posed a threat no longer — the odds that the asteroid would smash into our planet have dropped to nearly zero.“I knew this was likely to go away as we collected more data,” said Davide Farnocchia, a navigation engineer at the NASA Jet Propulsion Laboratory in California. “I was sleeping pretty well.”Days after skywatchers reported their observations of 2024 YR4 on Dec. 27, 2024, scientists calculated that it had more than a 1 percent chance of striking Earth — the only large asteroid known to have an impact probability so big.As scientists studied more data on the object, the odds of impact continued to rise through January and February, from 1.2 percent to a peak of 3.1 percent on Tuesday last week.That may sound small, but the probability was higher than any ever recorded by NASA for an object of this size or bigger.Somewhere between 130 and 300 feet wide, 2024 YR4 is big enough to potentially wipe out a city. Early estimates of the asteroid’s trajectory showed it could possibly slam into or explode in the air over large metropolitan areas, including Mumbai, India, and Lagos, Nigeria.

      Elon Musk’s SpaceX, Already a Leader in Satellites, Gets Into the Spy Game

      by

      The Pentagon needs what the company offers to compete with China even as it frets over its potential for dominance and the billionaire’s global interests.The breakthrough came last month, about 600 miles above Earth.For the first time, the Pentagon’s Space Development Agency used lasers transmitting data at light speed to communicate between military satellites on a secure network, making it easier to track enemy missiles and if necessary shoot them down.It was a milestone not only for the Pentagon. This was a defining moment for a certain up-and-coming military contractor that had built key parts of this new system: Elon Musk’s SpaceX.SpaceX over the last year started to move in a big way into the business of building military and spy satellites, an industry that has long been dominated by major contractors like Raytheon and Northrop Grumman as well as smaller players like York Space Systems.This shift comes as the Pentagon and U.S. spy agencies are preparing to spend billions of dollars to build a series of new constellations of low-earth-orbit satellites, much of it in response to recent moves by China to build its own space-based military systems.SpaceX is poised to capitalize on that, generating a new wave of questions inside the federal government about the company’s growing dominance as a military space contractor and Mr. Musk’s extensive business operations in China and his relations with foreign government leaders, possibly including President Vladimir V. Putin of Russia. Mr. Musk is also unpredictable in a sector in which security is often perceived to be synonymous with predictability. He chafes at many of the processes and rules of government, saying they hold back progress, and wants to make his own calls.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

      by

      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.

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

      by

      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.

      Starliner Capsule Returns, but Boeing’s Space Business Woes Remain

      by

      The capsule, which returned without astronauts, and other space programs at Boeing have suffered many delays and cost overruns.Space programs are a small part of Boeing’s business, which is dominated by sales of commercial and military planes and equipment. But the work is a point of pride: Boeing has long been involved in spaceflight, going back to the first mission to take an American to space.But Boeing’s efforts to add to that space heritage are in doubt.The company’s Starliner capsule returned to Earth safely from the International Space Station on Friday night, but without the two astronauts it took up there in June because NASA was concerned about thrusters on the capsule that had malfunctioned before it docked at the station.A decade ago, NASA chose Boeing and an upstart rival, SpaceX, to ferry astronauts to and from the space station. SpaceX has since carried out seven of those missions and will bring home the astronauts Starliner left behind, while Boeing has yet to complete one. And with the station set to retire as soon as 2030, time is running out.“It’s unclear if or when the company will have another opportunity to bring astronauts to space,” Ron Epstein, an aerospace and defense analyst at Bank of America, said in a research note last month. “We would not be surprised if Boeing were to divest the manned spaceflight business.”On Thursday, asked to comment on Starliner’s problems and the future of its space business, Boeing responded with this statement: “Boeing continues to focus, first and foremost, on the safety of the crew and spacecraft. We are executing the mission as determined by NASA, and we are preparing the spacecraft for a safe and successful uncrewed return.”Boeing’s troubles could be a setback not only for the company but for the U.S. space program more broadly, which wants multiple private companies available to ably support its efforts.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      What to Know About the Blue Supermoon

      by

      The celestial event, which is visible from Sunday to Wednesday morning, probably won’t happen again until 2037.Stargazers are being treated to an astronomical show this week as an infrequent blue supermoon lights up the night sky, one of the largest and brightest full moons of the year.Visible from late Sunday through Wednesday, it will be the first of the year’s four consecutive supermoons. But it’s a special instance, because Sunday’s supermoon is also a seasonal blue moon — the third full moon in a season of four.The full moon will appear larger and brighter than usual.The term “supermoon,” coined by the astrologer Richard Noelle in 1979, refers to a moment when the full moon is closest to Earth on its orbital path. It’s not an official astronomical term, but it is used by the lay-stargazers among us. A “blue” moon bears no connection to the color blue, and the moon won’t have a colorful tinge. Instead, a blue moon is used to describe what is effectively an additional full moon, one that violates the rule of thumb, that there is one full moon in a month, or three full moons in a season.Supermoons, full moons and blue moons occur on their own, but it’s not often that they all happen at the same time. According to NASA, roughly 25 percent of full moons are supermoons, and only 3 percent of full moons are blue moons. From Sunday through Wednesday morning, they’ll occur simultaneously.Supermoons can appear 30 percent brighter than the average moon.Like “supermoon,” the term “blue moon” is also colloquial, but blue moons are infrequent — more so than supermoons — and tend to occur every few 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.

      Wildlife Protections Take a Back Seat to Elon Musk’s Ambitions

      by

      As Elon Musk’s Starship — the largest rocket ever manufactured — successfully blasted toward the sky last month, the launch was hailed as a giant leap for SpaceX and the United States’ civilian space program.Two hours later, once conditions were deemed safe, a team from SpaceX, the U.S. Fish and Wildlife Service and a conservation group began canvassing the fragile migratory bird habitat surrounding the launch site.The impact was obvious.The launch had unleashed an enormous burst of mud, stones and fiery debris across the public lands encircling Mr. Musk’s $3 billion space compound. Chunks of sheet metal and insulation were strewn across the sand flats on one side of a state park. Elsewhere, a small fire had ignited, leaving a charred patch of park grasslands — remnants from the blastoff that burned 7.5 million pounds of fuel.Most disturbing to one member of the entourage was the yellow smear on the soil in the same spot that a bird’s nest lay the day before. None of the nine nests recorded by the nonprofit Coastal Bend Bays & Estuaries Program before the launch had survived intact.Egg yolk now stained the ground.“The nests have all been messed up or have eggs missing,” Justin LeClaire, a Coastal Bend wildlife biologist, told a Fish and Wildlife inspector as a New York Times reporter observed nearby.The outcome was part of a well-documented pattern.On at least 19 occasions since 2019, SpaceX operations have caused fires, leaks, explosions or other problems associated with the rapid growth of Mr. Musk’s complex in Boca Chica. These incidents have caused environmental damage and reflect a broader debate over how to balance technological and economic progress against protections of delicate ecosystems and local communities.
