      ISS review – Ariana DeBose is ace as third world war sparks space station survival race

      news.movim.eu / TheGuardian · 06:00

    DeBose’s brilliant rookie astronaut navigates this moderately tense thriller about US and Russian crew fighting as Earth blazes below

    At first, the crew on board the International Space Station (ISS) mistake the tiny dot of fire on Earth for a volcano. But look: there’s another, and another. In fact, these astronauts have got a bird’s eye view of a nuclear tit-for-tat between the Russian and American governments that by the end of the movie turns the planet into a great glowing ball of fire. But for the six-person crew – three Americans and three Russians – nuclear Armageddon is only the start of their problems.

    A lowish-budget, slightly muted survival thriller – moderately tense, with too few ideas to qualify as actively cerebral – what the movie does have is a brilliant performance by West Side Story ’s Ariana DeBose as biologist and rookie astronaut Kira. Like all the characters here, she’s a bit too thinly sketched, but DeBose brings real warmth and likability to the part, making Kira easy to root for. And there are some interesting moments as she adjusts to zero gravity.

    Russia vetoed a United Nations Security Council resolution Wednesday that would have reaffirmed a nearly 50-year-old ban on placing weapons of mass destruction into orbit, two months after reports Russia has plans to do just that.

    Russia's vote against the resolution was no surprise. As one of the five permanent members of the Security Council, Russia has veto power over any resolution that comes before the body. China abstained from the vote, and 13 other members of the Security Council voted in favor of the resolution.

    If it passed, the resolution would have affirmed a binding obligation in Article IV of the 1967 Outer Space Treaty, which says nations are "not to place in orbit around the Earth any objects carrying nuclear weapons or any other kinds of weapons of mass destruction."

      If Starship is real, we’re going to need big cargo movers on the Moon and Mars

    As a SpaceX engineer working on the Starship program about five years ago, Jaret Matthews could see the future of spaceflight quite clearly and began to imagine the possibilities.

    For decades everything that went to space had to be carefully measured, optimized for mass, and serve an extremely specialized purpose. But Starship, Matthews believed, held the potential to change all that. With full reusability, a barn-size payload fairing, and capability to loft 100 or more metric tons to orbit in a single throw, Starship offered the tantalizing prospect of a world in which flying into space was not crazy expensive. He envisioned Starships delivering truckloads of cargo to the Moon or Mars.

    Matthews spent a decade working on robots and rovers at NASA's Jet Propulsion Laboratory before coming to SpaceX in 2012. He began to suggest that the company work on a system that could unload and distribute cargo from Starship, like the cranes and trucks that offload cargo from large container ships in port. However, he didn't get far, as SpaceX was focused on developing the Starship transportation system.

      SpaceX has now landed more boosters than most other rockets ever launch

      news.movim.eu / ArsTechnica · 2 days ago - 15:00

    SpaceX landed its 300th booster on Tuesday.

    SpaceX launches have become extremely routine. On Tuesday evening, SpaceX launched its 42nd rocket of the year, carrying yet another passel of Starlink satellites into orbit. Chances are, you didn't even notice.

    All the same, the cumulative numbers are mind-boggling. SpaceX is now launching at a rate of one mission every 2.7 days this year. Consider that, from the mid-1980s through the 2010s, the record for the total number of launches worldwide in any given year was 129. This year alone, SpaceX is on pace for between 130 and 140 total launches.

    But with Tuesday evening's mission, there was a singular number that stood out: 300. The Falcon family, which includes the Falcon 9 and Falcon Heavy boosters, recorded its 300th successful first-stage landing.

      Recoding Voyager 1—NASA’s interstellar explorer is finally making sense again

      news.movim.eu / ArsTechnica · 3 days ago - 17:56

    Engineers have partially restored a 1970s-era computer on NASA's Voyager 1 spacecraft after five months of long-distance troubleshooting, building confidence that humanity's first interstellar probe can eventually resume normal operations.

    Several dozen scientists and engineers gathered Saturday in a conference room at NASA's Jet Propulsion Laboratory, or connected virtually, to wait for a new signal from Voyager 1. The ground team sent a command up to Voyager 1 on Thursday to recode part of the memory of the spacecraft's Flight Data Subsystem (FDS) , one of the probe's three computers.

    “In the minutes leading up to when we were going to see a signal, you could have heard a pin drop in the room," said Linda Spilker, project scientist for NASA's two Voyager spacecraft at JPL. "It was quiet. People were looking very serious. They were looking at their computer screens. Each of the subsystem (engineers) had pages up that they were looking at, to watch as they would be populated."

    Welcome to the Daily Telescope . There is a little too much darkness in this world and not enough light, a little too much pseudoscience and not enough science. We'll let other publications offer you a daily horoscope. At Ars Technica, we're going to take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder.

    Good morning. It's April 23, and today's photo comes from the Hubble Space Telescope. It features a lovely, barred spiral galaxy and a photobombing star on the right-hand side of the image.

    The galaxy is NGC 3783, which can be found 130 million light years away from Earth. Astronomical distances are all mind-boggling, but to try and put things into perspective, that means this galaxy is about 1,000 times the distance further from us compared to the diameter of our own Milky Way Galaxy. So it's far, far away.

    NASA has formally approved the robotic Dragonfly mission for full development, committing to a revolutionary project to explore Saturn's largest moon with a quadcopter drone.

    Agency officials announced the outcome of Dragonfly's confirmation review last week. This review is a checkpoint in the lifetime of most NASA projects and marks the moment when the agency formally commits to the final design, construction, and launch of a space mission. The outcome of each mission's confirmation review typically establishes a budgetary and schedule commitment.

    “Dragonfly is a spectacular science mission with broad community interest, and we are excited to take the next steps on this mission," said Nicky Fox, associate administrator of NASA's science mission directorate. "Exploring Titan will push the boundaries of what we can do with rotorcraft outside of Earth.”

    Several "high-profile astronomers" will meet at London's Royal Society (the UK's national academy of sciences), "to question some of the most fundamental aspects of our understanding of the universe.reports Futurism: As The Guardian reports, the luminaries of cosmology will be re-examining some basic assumptions about the universe — right down to the over-a-century-old theory that it's expanding at a constant rate. "We are, in cosmology, using a model that was first formulated in 1922," coorganizer and Oxford cosmologist Subir Sarkar told the newspaper, in an apparent reference to the year Russian astronomer Alexander Friedmann outlined the possibility of cosmic expansion based on Einstein's general theory of relativity. "We have great data, but the theoretical basis is past its sell-by date," he added. "More and more people are saying the same thing and these are respected astronomers." A number of researchers have found evidence that the universe may be expanding more quickly in some areas compared to others, raising the tantalizing possibility that megastructures could be influencing the universe's growth in significant ways. Sarkar and his colleagues, for instance, are suggesting that the universe is "lopsided" after studying over a million quasars, which are the active nuclei of galaxies where gas and dust are being gobbled up by a supermassive black hole. The article notes that another theory is that the so-called cosmological constant that's been used for decades "actually varies across space."
