      SpaceX Polaris Dawn Spacewalk: How to Watch the Astronauts

      by

      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

      by

      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.

      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.

      NASA Picks 3 Companies to Help Astronauts Drive Around the Moon

      by

      The agency’s future moon buggies will reach speeds of 9.3 miles per hour and will be capable of self-driving.NASA will be renting some cool wheels to drive around the moon.Space agency officials announced on Wednesday that they have hired three companies to come up with preliminary designs for vehicles to take NASA astronauts around the lunar south polar region in the coming years. After the astronauts return to Earth, these vehicles would be able to self-drive around as robotic explorers, similar to NASA’s rovers on Mars.The self-driving capability would also allow the vehicle to meet the next astronaut mission at a different location.“Where it will go, there are no roads,” Jacob Bleacher, the chief exploration scientist at NASA, said at a news conference on Wednesday. “Its mobility will fundamentally change our view of the moon.”The companies are Intuitive Machines of Houston, which in February successfully landed a robotic spacecraft on the moon; Lunar Outpost of Golden, Colo.; and Venturi Astrolab of Hawthorne, Calif. Only one of the three will actually build a vehicle for NASA and send it to the moon.NASA had asked for proposals of what it called the lunar terrain vehicle, or L.T.V., that could drive at speeds up to 9.3 miles per hour, travel a dozen miles on a single charge and allow astronauts to drive around for eight hours.The agency will work with the three companies for a year to further develop their designs. Then NASA will choose one of them for the demonstration phase.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Odysseus Moon Lander Sends Photos Home Before Spacecraft Likely Dies

      by

      The privately built American spacecraft’s ability to send home images and other data has been limited by its sideways landing. On another part of the moon, a Japanese spacecraft woke up.Odysseus, the American robotic spacecraft that landed on the moon last week, is likely to die in the next day or so.Communications with the toppled lander remain limited and will end when sunlight is no longer shining on the solar panels, Intuitive Machines, the Houston-based company that built and operates Odysseus, said on Monday morning.The company also released images that the spacecraft took as it descended, but none yet from the surface.Odysseus is the first American spacecraft to land on the moon since Apollo 17 in 1972, and the first private one ever to successfully set down there in one piece. However, during the landing on Thursday evening, the lander, about 14 feet tall, appears to have been traveling faster than planned and ended up tipped over on its side.As a result, its antennas are not pointed back at Earth, greatly slowing the rate that data can be sent back. While some of the solar panels of Odysseus were initially bathed in sunlight, they will soon be in shadow as the sun moves across the sky. That will starve the spacecraft of energy, and its batteries will drain.“Flight controllers intend to collect data until the lander’s solar panels are no longer exposed to light,” Intuitive Machines posted on X. “Based on Earth and Moon positioning, we believe flight controllers will continue to communicate with Odysseus until Tuesday morning.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Moon Lander Is Lying on Its Side but Still Functional, Officials Say

      by

      The Odysseus spacecraft was drifting horizontally as it set down, and a landing strut may have hit an obstacle on the surface.One day after its historic landing, the first private spacecraft on the moon is in good condition but has toppled over, the company that built it reported on Friday.The spacecraft, named Odysseus, set down in the moon’s south pole region on Thursday evening, the first U.S. vehicle to land softly on the moon since Apollo 17 in 1972.“The vehicle is stable near or at our intended landing site,” Steve Altemus, the chief executive of Intuitive Machines said during a NASA news conference on Friday. “We do have communications with the lander.”He added, “That’s phenomenal to begin with.”But the landing did not go perfectly. Because the spacecraft fell over, its antennas are not pointed directly at Earth, limiting the amount of information that can go back and forth.Odysseus has not sent back any photographs since landing, although Mr. Altemus did show one that was taken while the spacecraft was descending to the surface. “You see how shadowed and undulating the terrain is,” he said.Engineers at Intuitive Machines are still trying to extract more information from the spacecraft.Mr. Altemus and Tim Crain, the chief technology officer, also described unforeseen glitches that nearly doomed the mission. The landing was salvaged through serendipity and frantic work, they said.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Odysseus Spacecraft Lands on Moon, First Time for U.S. Since 1972

      by

      For the first time in a half-century, an American-built spacecraft has landed on the moon.The robotic lander was the first U.S. vehicle on the moon since Apollo 17 in 1972, the closing chapter in humanity’s astonishing achievement of sending people to the moon and bringing them all back alive. That is a feat that has not been repeated or even tried since.The lander, named Odysseus and a bit bigger than a telephone booth, arrived in the south polar region of the moon at 6:23 p.m. Eastern time on Thursday.The landing time came and went in silence as flight controllers waited to hear confirmation of success. A brief communication pause was expected, but minutes passed.Then Tim Crain, the chief technology officer of Intuitive Machines, the Houston-based company that built Odysseus, reported that a faint signal from the spacecraft had been detected.“It’s faint, but it’s there,” he said. “So stand by, folks. We’ll see what’s happening here.”A short while later, he announced, “What we can confirm, without a doubt, is our equipment is on the surface of the moon and we are transmitting. So congratulations.”Later, he added, “Houston, Odysseus has found its new home.”But with the spacecraft’s ability to properly communicate still unclear, the celebration of clapping and high-fives in the mission control center was muted.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Jeff Bezos’ Blue Origin Rocket Moves Closer to Launch

      by

      Blue Origin’s New Glenn rocket rolled to the launchpad for a series of tests in preparation for its maiden flight later this year.There’s an easy knock against the space dreams of Jeff Bezos and his rocket company, Blue Origin: In its 24th year of existence, the company has yet to launch a single thing to orbit.Blue Origin’s accomplishments to date are modest — a small vehicle known as New Shepard that takes space tourists and experiments on brief suborbital jaunts. By contrast, SpaceX, the rocket company started by the other high-profile space billionaire, Elon Musk, today dominates the launch market.On Wednesday, Blue Origin hopes to change the narrative, holding a coming-out party of sorts for its new big rocket.In the morning, at Launch Complex 36 at the Cape Canaveral Space Force Station in Florida, the doors to a giant garage opened. The rocket, as tall as a 32-story building, lay horizontally on the trusses of a mobile launch platform.The contraption was sitting on a transport mechanism that resembles several long mechanical centipedes, but with wheels, 288 in all, instead of feet. It began rolling slowly out and up a concrete incline, a quarter-mile trip toward the launchpad.The rocket will undergo at least a week of tests before returning to the garage.“I’m very confident there’s going to be a launch this year,” Dave Limp, the chief executive of Blue Origin, said in an interview. “We’re going to show a lot of progress this year. I think people are going to see how fast we can move.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
