With its sweeping tempo and ethereal melody, Austrian composer Johann Strauss II's "The Blue Danube" waltz has become synonymous with outer space and science fiction ever since it was chosen by Stanley Kubrick for 1968's "2001: A Space Odyssey."
Now "The Blue Danube" waltz with its whirling orbital rhythms will truly become the music of the cosmos when the European Space Agency broadcasts the lilting classical piece into deep space in celebration of the agency's 50th anniversary this year, in addition to the bicentennial of Johann Strauss II's birth in 1825.
Performed by the Wiener Symphoniker (Vienna Symphony Orchestra), this definitive anthem of space and sci-fi will be transmitted towards NASA's Voyager 1 probe by ESA's 35-meter Deep Space Antenna in Cebreros, Spain. Space fans and music lovers can watch an entire 15-minute livestream on the event's official website and on their YouTube or Instagram Channel regardless of your location, starting at 3:30 p.m. ET (1930 GMT) on Saturday (May 31).
Known in its native German as "An der schönen blauen Donau" which translates into "By the Beautiful Blue Danube," the sublime composition's 13,743 notes are being broadcast into the interstellar void on a mission that "is both a tribute to the past and a testament to the future – a Viennese Waltz that will echo through space forever," according to the event's website.
Composed by Strauss in 1866 as a consolatory gift to the Viennese people after defeat in the Austro-Prussian War, "The Blue Danube" was conceived from a poem describing the Danube River by Karl Isidor Beck that contained the phrase "beautiful blue Danube."
It's one of the most widely recognized pieces of classical music in the world, partly due to its Hollywood history, its associations with space, and being a universally-loved audience favorite in concert halls around the globe.
In a pivotal transition scene from director Stanley Kubrick's magnum opus "2001: A Space Odyssey," the film cuts from a twirling bone during the dawn of early humans to an orbiting nuclear weapons platform in the future as the camera follows a needle-nosed Pan Am spaceship drifting towards a gently turning space station. The tune continues on as another shuttle docks at the Clavius moonbase built on the lunar surface.
Fans also might recall "The Blue Danube Waltz" being employed in an episode of "The Simpsons" where Homer opens a smuggled bag of potato chips ("Careful, they're ruffled!") inside a space shuttle and proceeds to catch floating chips in his mouth along to the swaying melody of the Strauss melody.

The King of Waltz's iconic musical masterpiece wasn't included in NASA's Voyager space probes' Golden Records launched into space back in 1977, but this Waltz into Space aimed at Voyager 1 will correct that glaring oversight.
Currently, Voyager 1 is traveling 15.4 billion miles (24.8 billion kilometers) from Earth, taking this celebratory signal roughly 23 hours and 3 minutes to reach the historic spacecraft.

‘From the World of John Wick: Ballerina' Review: Dance, Killer, Dance!
With a title as cumbersome as its germinating mythology, 'From the World of John Wick: Ballerina' is a stone-cold, self-infatuated effort to couple another boxcar to the franchise money train. I regret to report that Keanu Reeves's titular assassin does not appear in a tutu. He does pop in, though, ever so briefly, lest we lose interest before the promised fifth installment. Set during the events of 'John Wick: Chapter 3 — Parabellum' (2019), 'Ballerina' is besotted with Eve Macarro (Ana de Armas), a lithe and lovely orphan who saw her father murdered and is obsessed with revenge. Inducted into the Ruska Roma, a cultlike clan whose ballet school fronts a contract-killer training facility, Eve practices pirouettes and punches with equal enthusiasm. Her toes are bloody, but her resolve is undimmed. A luxe orgy of mass murder, 'Ballerina' dances from one bloody melee to another, its back-of-a-matchbook plot (by Shay Hatton) driven solely by arterial motives. As Eve defies the ballet school's director (Anjelica Huston, more formidable than a roomful of Baryshnikovs) to pursue the well-protected head of a rival clan, the movie tends the franchise flame with a Wick-world checklist of familiar tropes. Like the impossibly creative, perfectly executed, utterly ridiculous fight sequences, which include Eve's father single-handedly overcoming a literal boatload of would-be assassins, or Eve laying waste to the lethal residents of an entire Austrian village. Outlandish weaponry is a given, and 'Ballerina' delights in deploying everything from expensive cookware to ice skates. There's even a hulking, Dolph Lundgren type wielding a flamethrower. From time to time, the feverish slaughter pauses respectfully to allow English and Irish acting legends to inject brief moments of gravitas. Ian McShane's menacingly dapper Winston is around to offer foster-fatherly advice and drop murky hints about Eve's true parentage, and Gabriel Byrne appears as the mysterious head of the rival family and the bearer of further familial secrets. It's all a bit much for Eve, who seems more relieved than scared when Wick himself shows up with a contract to stop her one-woman rampage. I suspect the audience will be equally thankful.

Europe stages a moon landing to learn how to photograph the real thing (photos)
When you buy through links on our articles, Future and its syndication partners may earn a commission. Pictures from a simulated moon landing, not designed to fool anyone into believing a fake but rather to provide a reference to make sure that we can get the best video images possible when astronauts finally do return to the moon, have been released by the European Space Agency (ESA). When Neil Armstrong clambered down the Eagle's lander to take his "one giant leap" in 1969, it was captured by a black-and-white slow-scan television (SSTV) with a resolution of a mere 320 lines and 10 frames per second. The transmission, beamed back via NASA's Deep Space Network, was sketchy, plagued by ghosts and poor contrast. The available 900 to 1,000 kiloHertz bandwidth just wasn't sufficient to transmit in color. Things improved slightly with Apollo 12, which had a wider 2 to 3 megaHertz bandwidth that permitted color footage — at least until the video camera was accidentally pointed at the sun, the solar intensity damaging its vacuum tube. Soon, NASA's Artemis crewed moon missions will be flying with high-definition and ultra-high definition color cameras with frame rates of up to 60 per second. But even though the technology has dramatically improved since 1969, there remain many challenges for successfully documenting a lunar landing on video. Bandwidth continues to be one of these challenges, as does the 1.3-second signal delay from the moon, dealing with bright sunlight starkly reflecting off the lunar surface, and moon dust that seems to be able to find its way into every nook and cranny. Therefore, taking detailed images and video footage of activities on the lunar surface and transmitting them back to Earth, all within the constraints of these challenges, is an acquired skill. We can't yet just pop to the moon to practice, so the next best thing is to simulate the environment of the moon somewhere on Earth. Indeed, this is the purpose of the LUNA facility in Cologne, Germany, which is a joint project between ESA and the German Aerospace Center (known by its German acronym DLR). The idea is to create a lunar environment that is as realistic as possible for testing robotic landers, training astronauts and practicing with equipment — including, in this case, cameras. To that end, imaging experts from the Consultative Committee for Space Data Systems (CCSDS), which features representatives from 28 countries, have convened on LUNA to practice shooting astronauts playing make-believe in a simulated lunar environment. Spending time at LUNA gave imaging expert Melanie Cowan, who is ESA's representative on the CCSDS' Motion Imagery and Applications Working Group team, "a glimpse of what it may be like on the moon," she said in a statement. "One cannot get any closer to the real thing. It was a special and challenging experience to film and photograph in this surreal environment." Indeed, so realistic was this pretend moon that Cowan and fellow imaging experts had to wear protective clothing to prevent the simulated lunar dust from being breathed in, or getting in their hair or on their clothes. Dust could be a major problem for astronauts spending any appreciable time on the surface; it is so fine that it gets everywhere, sticking to surfaces and potentially clogging up equipment. So, donned in their protective clothing reminiscent of the head-to-toe suits used in clean rooms, the imaging experts captured footage of astronauts descending from a mock lunar lander, exploring the surface and even taking a selfie — something that Neil Armstrong may have wished he'd had the opportunity to do. (There are famously few images of Armstrong on the moon, since he carried the Hasselblad camera during most of his and Buzz Aldrin's historic moonwalk.) The point behind taking the selfie was to see how much detail could be captured in the reflection on the visor of the astronaut's helmet. The resulting images and video are intended to be used as reference files for the real thing, so that astronauts and imaging technicians can better understand what camera settings to use, and how large the resulting image or video files might be when transmitted. "These efforts should help agencies and companies create a ground truth for video applications and equipment," said Falk Schiffner, who is the DLR representative in the CCSDS Motion Imagery and Applications Working Group. "The activities to refine video quality are not geared only to moon imagery, but to all space transmissions." Capturing good footage on the moon is not as easy as on Earth. For one thing, because there is no appreciable atmosphere on the moon to scatter sunlight, the contrast between areas directly illuminated by the sun and areas in black shadow can lead to over-exposed daylight areas and totally black shadowed regions. And the slow rise and setting of the sun over a two-week period from any given location results in slowly changing conditions. To replicate all of this at the LUNA facility required a lot of trial and error with camera angles and lighting. "We tried different sun simulators and techniques to replicate the lighting of the sun on the moon," said Cowan. "We investigated the effects of the shadows from the rocks and inside craters. Early tests revealed that HDR video will provide more detail in shadowed areas on the lunar surface." Related stories: — European Space Agency: Facts & information — Apollo 11: First men on the moon — NASA's Artemis program: Everything you need to know HDR stands for "high dynamic range," which can drastically improve the contrast ratio of an image, or boost its colors. Camera manufacturer Nikon has already teamed up with NASA to develop modified Nikon Z9 cameras to be used by astronauts should they land on the moon as part of the eventual Artemis 3 mission. The Nikon Z9 possesses both HDR and UHD (ultra-high definition) capabilities that will be essential for use in the strange, stark lunar landscape. Taking an 8K UHD video camera to the moon is one thing, but transmitting all that data back to Earth in a livestream (or as live as it can be with the 1.3-second delay) has limitations in the available bandwidth. In particular, footage containing lots of motion is referred to as an "encoder killer," as it bumps the data rate way up. In practice, data transmission from the moon will be compressed, just as it already is from the International Space Station, for example, but even then methods will have to be found to squeeze it all into the available bandwidth without losing too much data. Help may soon be coming thanks to ESA's Moonlight initiative, which plans to launch a constellation of five satellites into orbit around the moon. Four of these spacecraft will assist future missions with navigation, and the other will provide high-data-rate communications between the lunar surface, spacecraft in lunar orbit or traveling to the moon, and ground stations on Earth. The intent is for Moonlight to be fully operational by 2030.

Movie Review: Ana de Armas is better at killing than ballet in ‘Ballerina,' a John Wick spinoff
Watch a bunch of John Wick movies all in a row, and you can get pretty paranoid. You start to think everyone's an assassin. The guy at the newsstand, the street musician, the subway rider, that nice neighbor in the elevator — ruthless contract killers, all. So perhaps it shouldn't be too surprising that in 'From the World of John Wick: Ballerina,' the latest installment in the Wickian world, we reach the logical endpoint: a town where every single inhabitant's a killer. Yes, it's a picture-perfect, snowy winterscape in Austria, where everyone wears wool beanies and very nice sweaters. But they also wield a mean flamethrower, and schoolkids have mandatory shooting practice. The early scenes in this wacky place high in the mountains are the best part of 'Ballerina' — they actually contain deft surprises and even a glimmer of humor, which is hardly something we expect in a John Wick film. (Have you ever see the guy smile?) Watching our energetic star, Ana de Armas, engage in a plate-smashing contest with a sweet waitress-turned-vicious-killer reminds us that action can be clever, even if most scenes in this series inevitably become numbing, as the body count rises stratospherically. Before we go further, some clarification on where this film fits into the timeline. Let's forget (for now) that there was a John Wick 4, because the events of 'Ballerina' take place during the third movie. So, erase from your mind whatever huge, life-altering thing may or may not have happened in the last film. OK? Eagle-eyed viewers may, in fact, remember a brief scene in the third movie where a ballerina is trying to do a series of fouettés, those whiplash turns on one leg that are a big attraction in 'Swan Lake.' The same scene returns in 'Ballerina,' where we see de Armas' character, Eve, doggedly trying to master them in training. Why she keeps falling — every time, after years and years of class — is a mystery. We don't aim for full realism in action films, guys, but may we suggest that falling flat on the floor in your pointe shoes every time you do a turn feels like much more difficult stunt work than anything else in 'Ballerina' — including obliterating a horde of townspeople. It also speaks to a troubling lack of coordination, a definite problem for an assassin. Anyway! We actually first meet Eve as a child, living alone with her cherished father in some wind-swept coastal abode. Suddenly, a crew of black-clad assassins arrives by sea, targeting the father. He manages to protect Eve, but dies from his wounds. Soon, now-orphaned Eve is approached by Winston (Ian McShane, returning) owner of the Continental Hotel. Winston says he can bring her to her father's family. He takes her to The Director (a haughty Anjelica Huston), who welcomes the budding dancer to what seems an elite ballet academy but is also the training ground of the Ruska Roma, the crime organization where Wick himself learned his trade. The years go by. Eve is now a young woman determined to strike out on her own, though she still has problems completing a fouetté turn. ('Tend to your wounds before you get sepsis and we have to cut off your feet,' the Director suggests helpfully.) Luckily she shows more aptitude with firearms. And that's important, because her overriding goal is to avenge the death of her father. So when Wick himself (Keanu Reeves, of course, appearing in a few key scenes) makes a crucial stop at the academy, Eve looks at him and asks, 'How do I get out of here?' 'The front door is unlocked,' Wick replies – a line that got applause at the screening I was at, but so did virtually everything Wick said or did. 'No, how do I start doing what YOU do?' Eve asks. Wick tells her she can still leave — she has the choice to reject a killer's life. The sad subtext: He does not. But while Wick wants out — always — Eve wants IN. Otherwise we wouldn't have a movie. And so, her quest for vengeance takes her, clue by dangerous clue (and against the Director's strict orders) to the snowy hamlet of Hallstatt. There, the fearsome Chancellor (Gabriel Byrne, duly chilly) leads a band of assassins — all of whom want to kill her. Oh, also: the Chancellor killed her dad. And so Eve has to fight, using all the training and ingenuity she has amassed. One lesson she must draw on, from a trusted teacher: 'Fight like a girl.' In this case, as you can imagine, that's not a derogatory phrase. What it means is to lean into your strengths — you won't beat a man by brute force, the teacher has told her, but with smarts and inventiveness. That means using ever more interesting weapons to kill an endless supply of people (it must be said, the cheers from moviegoers are, as ever, disconcerting.) And, by the end, getting pretty comfortable with a flamethrower. 'From the World of John Wick: Ballerina,' a Lionsgate release, has been rated R by the Motion Picture Association 'for strong/bloody violence throughout, and language. ' Running time: 125 minutes. Two stars out of four.
