Crew 10's Stellar Launch, Earth's Electric Mysteries, and a Blazar's Cosmic Conundrum: S04E64

Today on Astronomy Daily, we have an action packed episode filled with big developments from across the cosmos. We'll start with the successful launch of NASA's SpaceX Crew ten mission, which is now carrying four new crew members to the International Space Station. We'll also explore NASA's groundbreaking Easy mission that's set to study the mysterious electrical currents flowing around Earth's poles. Then we'll venture into deep space to examine a cosmic mystery that's baffling astronomers, a shape shifting blazaar that's breaking all the rules we thought we knew about these powerful objects. From there, we'll check in on China's Tiangong Space Station and their busy schedule of experiments in future missions. And finally, we'll look at how Earth's newest astronomical eye, the Vera Reuben Observatory, might help guide NASA's new Horizon spacecraft to new discoveries in the distant Kuiper Belt. So let's get started with the news we've all been waiting to hear. In a spectacular nighttime launch from NASA's Kennedy Space Center in Florida, SpaceX's Falcon nine rockets successfully lifted off at seven oh three pm EDT on Friday, carrying the Crew ten mission toward the International Space Station. The Dragon spacecraft carried an international quartet of space travelers, NASA astronauts Anne McLain and Nicole Ayr's Jaksa astronaut to Kuya Onishi, and Rascosmos cosmonaut Kirol Peskov. For commander Anne maclain, this marks her second journey to the orbital outpost, while mission pilot Nicole Ayers is embarking on her first space flight to kuy Onishi is making his second trip to the station, and Kirol Peskov is experiencing his first venture into space. The Dragon spacecraft is scheduled to dock autonomously with the station's Harmony Module, where the new arrivals will temporarily bring the station's crew complement to eleven. This highlights the increasingly busy nature of our orbital outpost and the growing international cooperation in space exploration. During their stay aboard the station, the Crew ten tis will conduct numerous scientific investigations, including material flammability tests that will help inform future spacecraft design. They'll also engage with students worldwide through the iss HAM Radio program and participate in physiological studies that will provide crucial data for future deep space missions. This mission represents the tenth crew rotation under NASA's Commercial Crew program, demonstrating the success of the agency's partnership with private industry. As Acting NASA Administrator Janet Petro noted, these missions are laying the groundwork for future exploration from low Earth orbit to the Moon and eventually Mars. The successful launch of Crew ten continues the remarkable achievement of maintaining a continuous human presence in space, with the International Space Station now having been continuously occupied for more than twenty four years. This mission not only advances our scientific understanding, but also strengthens the international bonds that make space exploration possible. It also means that Butch and Sunni can finly come home, and we should see them back on Earth shortly. NASA's newest mission to study Earth's auroras is preparing for launch, with three small but mighty spacecraft ready to unlock the mysteries of the spectacular light shows we know as the Northern and Southern Lights. The Electrojet Zeman Imaging Explorer, or EASY for short, represents the first dedicated mission to study auroral electrojets powerful electrical currents flowing high in our planet's atmosphere near the poles. These remarkable currents can push up to a million amps of electricity through the upper atmosphere, about sixty five miles above Earth's surface. To put that in perspective, that's enough electrical current to power hundreds of thousands of homes. The mission will use three cube SATs, each about the size of a carry on suitcase, working together like pearls on a string as they orbit from pole to pole between two hundred and sixty to three hundred seventy miles up. What makes easy particularly clever is how these satellites will work together. Instead of carrying propulsion systems, they'll use atmospheric drag to maintain their formation, carefully rotating to adjust their spacing so each spacecraft passes over the same region just minutes after the previous one. This will give scientists an unprecedented look at how these electrical currents evolve over time. The satellites will detect these currents by observing microwave emissions from oxygen molecules about ten miles below the electrojets. The currents create a magnetic fingerprint in these emissions, which Easy's instruments are specifically designed to measure. Each satellite will create detailed maps of the electrojets during every orbit, and combining data from all three will reveal how these current systems change and develop. Beyond advancing our understanding of Earth's electrical environment, Easy will help improve our ability to predict space weather events that can affect satellites and power grids. The mission is also engaging students and citizen scientists through the easy mag program, distributing magnet actometer kits across the United States to allow people to make their own measurements of these vast electrical current systems. The mission is scheduled to operate for eighteen months, during which time it will not only help us better understand our own planet's magnetic environment, but also provide insights that could apply to any magnetized planet in our Solar System and beyond. This relatively small mission could have big implications for our understanding of how planets interact with space. Next up, just when astronomers thought they had blazars all figured out, one peculiar cosmic object is completely rewriting the rule book bl Lacertae located about nine hundred million light years away in the constellation Lecerta, has been leaving scientists scratching their heads with its unprecedented behavior. Initially mistaken for just another variable star in our galaxy when it was discovered in nineteen twenty nine, BL Lacertae turned out to be something far more exotic, a powerful active galaxy shooting intense jets of matter toward Earth. These are objects known as blazars, typically fall into neat categories based on their electromagnetic emissions, but BL Lacertae seems determined to break every classification we throw at it. Recent observations between twenty twenty and twenty twenty three have shown this cosmic rebel rapidly switching between different blazar types, something that should be impossible according to our current understanding. One moment, it appears as what astronomers call an HBL, then suddenly transforms into an LBL, before settling briefly as an IBL, only to change again. It's like watching a cosmic chameleon that can't make up its mind. The X ray emissions from BL lassert have also reached record breaking levels during this period. While scientists believe they understand how blazars produce their characteristic double peaked emission patterns, with electrons and their synchrotron radiation responsible for the lower energy peak, the mechanism behind the rapid switching between types remains a complete mystery. This bizarre behavior has sparked intense debate in the astronomical community. Could b L Lacertae represent an entirely new class of blazar or is there some unknown physical process at work that allows it to change its emission patterns at unprecedented speeds. These questions are keeping theoretical astrophysicists up at night as they struggle to explain what they're seeing. The discovery challenges our fundamental understanding of how these powerful cosmic engines operate and reminds us that the universe still has plenty of surprises in store. As one of the earliest discovered blazars continues to defy explanation, it's clear that we still have much to learn about these fascinating cosmic objects. Let's get an update now from another spacefaring nation. China's space program continues to make impressive strides with their Chiangong space station, which has been continuously occupied since its completion in late twenty twenty two. The current crew aboard the station Shunho nineteen, is over one hundred and thirty days into their six month mission and has been conducted groundbreaking research in orbit. The three person crew, led by Commander Chai Shuje, alongside crew members Songling Dong and Wang Housi, has been particularly busy with cutting edge experiments. They've been working extensively with electro andcephalogram equipment to study how microgravity affects visual processing and exploring how brain wave music might help astronauts maintain better cognitive control during extended space missions. Wang Houzi, who made history as China's first female flight engineer in space, has been demonstrating the crucial exercise protocols using resistance bands that help combat the muscle and bone loss that naturally occurs in zero gravity. The crew has also been pushing the boundaries of human machine interaction, working with an AI robot called Xiaohang to develop more intuitive ways for astronauts to communicate with automated systems. Looking ahead, China has ambitious plans for Changong in twenty twenty five. The Space Agency CMS has announced two crude missions Shunzo twenty and twenty one, along with a Tianjo cargo spacecraft to keep the station well supplied. In an exciting development for international cooperation, China will also be training Pakistani astronauts for an upcoming short term mission to Changong. This steady progress demonstrates China's growing capabilities in space exploration and their commitment to maintaining a permanent human presence in orbit. As the Shenzo nineteen crew continues their scientific work, they're not just advancing our understanding of space. They're helping pave the way for an increasingly diverse and collaborative future in space exploration. The outer reaches of our Solar System might soon become a lot less mysterious thanks to an exciting collaboration between one of our most distant spacecraft and a powerful new telescope. The Vera Reuben Observatory, set to begin operations later this year, could help chart a new course for NASA's New Horizon spacecraft as it ventures through the Kuiper Belt. The New Horizons, which gave us those stunning images of Pluto in twenty fifteen, is now about sixty one astronomical units from Earth that's sixty one times the distance between Earth and the Sun. While it's still functioning perfectly, it needs new targets to study, and that's where the Vera Ruben Observatory comes in. A team of scientists led by JJ Kavilars has proposed an innovative survey using the observatory's powerful capabilities. Their plan involves dedicating about thirty hours of telescope time across six different nights to conduct what they're calling a deep drilling microsurvey of the spacecraft's trajectory through the Kuiper Belt. This survey could potentially identify around seven hundred Kuiper Belt objects, and while finding one close enough for a direct flyby might be a long shot, the spacecraft could still make valuable observations of these distant objects. The team expects to discover numerous binary objects and possibly even contact binaries similar to Aricoth, which New Horizons famously visited in twenty nineteen. The Via Reuben Observatory's involvement could confirm recent findings suggesting the Kuiper Belt is more densely populated than our current models predict. If the initial survey proves insufficient for finding suitable fly by targets. The team is already thinking ahead to potentially using the upcoming Roman Observatory to conduct even more detailed searches. This collaboration between Earth based telescopes and our deep space pioneers represents a fascinating new chapter in our exploration of the Solar System's frontier, potentially revealing new secrets about these mysterious outer regions that have remained hidden from view for so long. Well that's it for today, from the successful launch of Crew ten to the International Space Station, to the groundbreaking easy emission studying our auroras and that fascinating shape shifting blazar that's got astronomers scratching their heads. We've also checked in with China's Tangong Space station and explored the citing possibilities for new horizons in the Kuiper Belt.
