NASA says it’s finished with having to do full-scale dress rehearsals for the first liftoff of its moon-bound Space Launch System rocket. But it’s not finished with having to make fixes.
“At this point we’ve determined that we’ve successfully completed the evaluations and the work that we intended to complete for the dress rehearsal,” Thomas Whitmeyer, NASA’s deputy associate administrator for common exploration systems development, told reporters today.
The world’s richest human wants to build a city on Mars: Fifty years ago, Elon Musk’s vision of our future on the Red Planet might have sounded like science fiction — but today, Musk is actually serious about the idea of using billions of dollars from ventures like SpaceX’s Starlink broadband network to finance the move to Mars.
“In looking in the long term, and saying what’s needed to create a city on Mars, well, one thing’s for sure: a lot of money,” Musk said back in 2015. “So we need things that will generate a lot of money.”
NASA has dipped into the debate over UFOs for decades, but today the space agency said it’s commissioning an independent study team to survey a wide range of what are now known as unidentified aerial phenomena, or UAPs.
“The most exciting things in science are things we don’t understand, and my starting point — I think all our starting points for this — is that there are phenomena that we don’t understand,” astrophysicist David Spergel, who’ll lead the study team, told reporters. “How do we start to make progress? We have a very limited set of observations right now with these UAPs. This makes it difficult to draw conclusions. So we start by trying to figure out what data is out there. We’re going to be working with government, nonprofits, companies, civilians, and try to identify what data is already there, then start to think about what data should we collect in the future.”
NASA’s independent study will start early in the fall and run in parallel to the Pentagon-led effort to analyze UAP reports from aviators, which was the focus of a congressional hearing last month.
NASA has struck deals with two commercial teams to provide the spacesuits destined for use when astronauts return to the moon by as early as 2025 — and there’s an extra twist that might have sounded alien to the Apollo moonwalkers a half-century ago. This time, NASA won’t own the suits.
For the first time in more than half a century, Congress conducted a public hearing into the state of the Pentagon’s study of unidentified aerial phenomena — which is the new name for mysteries once known as unidentified flying objects, or UFOs.
Scott Bray, deputy director of naval intelligence, told a hearing organized by the House Intelligence subcommittee on counterterrorism, counterintelligence and counterproliferation that military reports about UFOs — sorry, I mean UAPs — have been “frequent and continuing.”
Today’s hearing follows up on a Pentagon report that was issued last year and listed 144 UAP sightings that have been reported since 2004. The report pledged to take such sightings more seriously than in the past. “Since the release of that preliminary report, the UAP task force database has now grown to contain approximately 400 reports,” Bray said. “The stigma has been reduced.”
However, the hearing also made clear that the Department of Defense is still keeping mum about the detailed workings of its UAP detection and assessment process due to national security concerns. Bray and the hearing’s other witness — Ronald Moultrie, the under secretary of defense for intelligence and security — deferred a fair number of lawmakers’ questions to the closed session that followed the open hearing.
What is the multiverse? The idea that the universe we inhabit is just one of many parallel universes gets a superhero shout-out in “Doctor Strange in the Multiverse of Madness,” the latest movie based on Marvel comic-book characters.
And in the opinion of Brian Greene, a theoretical physicist at Columbia University, giving some screen time to the multiverse isn’t such a bad thing — even if the plot has some horror-movie twists.
“I think it’s really good if some of these ideas are brought out in a variety of different ways,” Greene says in the latest episode of the Fiction Science podcast, which focuses on the realm where science and technology intersect with fiction and popular culture.
Rocket Lab has just joined SpaceX in the club of space companies that can launch an orbital-class rocket booster and bring it back alive.
In a sense, the California-based company one-upped SpaceX by having a helicopter snag the first-stage booster of its Electron rocket with a cable and a hook as it floated past on the end of a parachute, 6,500 feet above the Pacific Ocean.
So what if the pilots of the customized Sikorsky S-92 helicopter had to release the booster moments later, due to concerns about the way their load was behaving as it swung from the hook?
Europe’s Large Hadron Collider has started up its proton beams again at unprecedented energy levels after going through a three-year shutdown for maintenance and upgrades.
It only took a couple of days of tweaking for the pilot streams of protons to reach a record energy level of 6.8 tera electronvolts, or TeV. That exceeds the previous record of 6.5 TeV, which was set by the LHC in 2015 at the start of the particle collider’s second run.
The new level comes “very close to the design energy of the LHC, which is 7 TeV,” Jörg Wenninger, head of the LHC beam operation section and LHC machine coordinator at CERN, said today in a video announcing the milestone.
When the collider at the French-Swiss border resumes honest-to-goodness science operations, probably within a few months, the international LHC team plans to address mysteries that could send theories of physics in new directions.
Axiom Space’s first crew of private astronauts is back on Earth after a 17-day orbital trip that included a week of bonus time on the International Space Station. The mission ended at 1:06 p.m. ET (5:06 p.m. GMT) today when SpaceX’s Crew Dragon Endeavour splashed down in the Atlantic Ocean off the coast of Florida.
Former NASA astronaut Michael Lopez-Alegria was the commander for the homeward trip, accompanied by three investors who each paid Axiom $55 million for their rides: Ohio real-estate and tech entrepreneur Larry Connor, who served as the mission pilot, plus Canada’s Mark Pathy and Israel’s Eytan Stibbe.
“Welcome back to planet Earth,” SpaceX’s mission control operator Sarah Gillis told the crew. “The Axiom-1 mission marks the beginning of a new paradigm for human spaceflight. We hope you enjoyed the extra few days in space.”
Axiom-1 began on April 8 with the Florida launch of a SpaceX Falcon 9 rocket. The trip was originally supposed to last about 10 days, but concerns about weather in the splashdown zone delayed the descent. Because of the way their fares were structured, Axiom’s customers didn’t have to pay extra for the extension.
Mood lighting, swanky seats, plants, a bar … and a restroom with an out-of-this-world view: Those are the sorts of perks you’d expect on a luxury cruise, but the cruise that Space Perspective plans to offer with those amenities will take you 100,000 feet up, lofted by a balloon.
Space Perspective says more than 600 customers have put in their reservations at a price of $125,000 for trips that are due to begin in 2024. And to whet your appetite for the adventure, the company is offering an interactive 3-D visualization of the capsule that you can wander through virtually.
