But that's not all. We'll also dive into the latest updates on space exploration, including some uncertainty surrounding Boeing's next crude mission. So buckle up and get ready for a cosmic journey through the latest and greatest in space and astronomy news. First up today, just because you're going to the Moon doesn't mean you can't be fashionable. In an exciting collaboration, Italian luxury brand Prada has joined forces with Houston based startup Axiom Space to create a cutting edge space suit for NASA's upcoming Artemis three mission to the Moon. This mission, planned for twenty twenty six, will mark the first astronaut moon landing since Apollo seventeen in nineteen seventy two. The new spacesuit, known as the Axium Extra Vehicular Mobility Unit or AXEMU, was recently unveiled at the International Astronautical Congress in Milan. While it maintains the familiar bulky white appearance we've come to associate with space suits, it now features added red trim and gray patches on the knees and elbows, giving it a subtle yet stylish update. But don't let its sleek look fool you. This suit is all about function. It's been designed to withstand the extreme temperatures at the lunar South Pole, including the ability to endure the coldest temperatures in permanently shadowed regions for at least two hours. The suit will also allow astronauts to perform space walks for up to eight hours, showcasing its impressive endurance capabilities. The AXIMU has already undergone extensive testing, including underwater simulations to mimic the lunar environment as it nears its final development stage. Both Prada and Axiom Space express pride in their collaborative effort, highlighting how the combination of their diverse skills has led to this innovative design. Next up, some space news from Europe. In exciting news for space enthusiasts, Italy's Vagacy rocket is gearing up for a comeback after facing some setbacks. The rocket is now scheduled to return to active duty on December third. This launch will mark a significant milestone for the Italian space program as the Vegacy resumes its role in delivering payloads to orbit. The return to flight is eagerly anticipated by the scientific community and space industry alike, as it represents another step forward in Europe's space capabilities. Now one for the Ausies amongst our listeners, stargazers in Australia get ready for a truly spectacular site. Comet C twenty twenty three A three, also known as suchinshan Atlas, is gracing our skies for the first time in a staggering eighty thousand years. This celestial wanderer has already been turning heads in the Northern Hemisphere and now it's Australia's turn to witness this rare cosmic event. This comet is not just any ordinary space rock. It's a time capsule from the very formation of our Solar System, offering us a glimpse into the distant past. Measuring about three point two kilometers across C twenty twenty three, A three hails from the mysterious Ort Cloud, a vast shell of icy objects surrounding our Solar System. What makes this visitor so special is its rarity. The last time it passed by Earth, our planet was still in the grip of the ice age, with mammoths and saber toothed cats roaming the land. It's mind boggling to think about the changes our world has undergone since its last visit. For the best view, keep your eyes on the western horizon during early evening. The bright planet Venus can serve as a helpful reference point. While visible to the naked eye, Binoculars or a small telescope will give you an even better look at this cosmic traveler and its characteristic tales. Don't miss this once in a lifetime opportunity to see a piece of our Solar System's ancient history. Comment Ce twenty twenty three A three is a reminder of the wonders that await us when we look up at the night sky. Next, an ongoing mystery is solved in a fascinating breakthrough. Astronomers have finally cracked a nearly thirty year old mystery surrounding the brown dwarf Gleiza two hundred twenty nine B. It turns out what we thought was a single celestial object is actually a pair of brown dwarfs locked in a cosmic dance. Brown dwarfs, for those unfamiliar, are fascinating objects that straddle the line between planets and stars. They're more massive than planets, but not quite hefty enough to sustain the nuclear fusion that powers stars. Glisa two hundred twenty nine B, discovered back in nineteen ninety five, has long been considered the poster child for brown dwarfs and has been the subject of numerous studies. However, something always seemed off about Gliza two hundred twenty nine B. Given its apparent mass, it should have been much brighter than observed. This discrepancy has puzzled scientists for decades until now, Using advanced instruments at the very large telescope in Chile, researchers have revealed that Gliza two hundred twenty nine B is actually two separate brown dwarfs. These cosmic twins, now dubbed Giza two hundred twenty nine BA and Gliza two hundred twenty nine b B, are roughly thirty eight and thirty four times the mass of Jupiter, respectively. They orbit each other every twelve days, far too close for previous observations to distinguish them as separate objects. This discovery not only solves the long standing brightness puzzle, but also provides valuable insights into the nature of brown dwarfs and the fuzzy boundary between stars and planets. It's a reminder that in astronomy, as in life, things aren't always what they seem at first glance. Scientists have recently made a groundbreaking discovery about the origins of meteorites that have fallen to Earth. It turns out that a wopping seventy percent of the seventy thousand meteorites found on our planet can be traced back to just three massive collisions in the main asteroid belt between Mars and Jupiter. These cosmic smash ups occurred five point eight, seven point five and forty million years ago, creating three young asteroid families known as Karen, Coronis, and Massalia. Each of these families formed when asteroids at least thirty kilometers across were destroyed, sending countless fragments hurtling through space. What's particularly fascinating is that these findings have solved a long standing mystery about the two most common types of meteorites, H chondrites and L chondrites. The Messalia family alone accounts for thirty seven percent of meteorites, including many L chondrites from a collision forty million years ago. This research not only sheds light on the origins of the space rocks we find on Earth, but also helps us track potentially dangerous asteroids that could pose a threat to our planet. It's a reminder of how interconnected our Solar system is and how events millions of miles away and millions of years ago continue to impact us today. One's looking skywards at the moment, even on Mars. In an exciting development from the Red Planet, NASA's Perseverance Rover has captured a stunning series of photographs showcasing a solar eclipse on Mars. On September thirtieth, the rover's left Masskamzi camera turned skyward to capture the planet's moon, Phobos, as it partially blocked the Sun's disc. These images offer a unique glimpse of Phobos, revealing its distinctive potato like shape. Unlike our spherical moon, Phobos is an irregularly shaped celestial body, measuring roughly seventeen miles by fourteen miles by eleven miles. It's a swift mover, orbiting Mars at an incredibly close distance of just three thousand, seven hundred miles and completing three orbits in a single Martian day. This isn't the first time Perseverance has captured such an event. The rover also photographed Phobos transiting the Sun in April twenty twenty two and February twenty twenty four. In fact, Perseverance is carrying on a proud tradition started by its predecessors. NASA's Spirit and Opportunity rovers first observed phobos solar transits back into thousand and four, while Curiosity made history by recording the first video of one in twenty nineteen. These observations aren't just for show, they help scientists better understand Mars's moons and the planet's complex orbital dynamics. It's a reminder that our robotic explorers on Mars are not only searching for signs of ancient life, but also acting as interplanetary astronomers, giving us a new perspective on celestial events from another world. Now an update to an ongoing story, NASA is still grappling with uncertainty regarding the next crude mission of Boeing's Starliner spacecraft. This comes in the wake of issues that arose during its first crude test flight earlier this year. The Space agency is currently in the process of reviewing the certification requirements for Starliner, a crucial step before giving the green light for future missions. The potential next crude mission to the International Space Station, initially slated for twenty twenty five, is now up in the air. NASA officials have stated that the timeline will be determined once they have a better grasp on Boeing's path to system certification. This thorough review is essential to ensure the safety and reliability of the spacecraft for future astronaut transport. The first crude test flight, known as crew Flight Test or CFT launched successfully on June fifth. However, problems arose during the docking procedure with the ISS. On June sixth, five out of twenty eight thrusters in the capsule's reaction control system experienced issues, causing a delay in the docking process. While the astronauts ultimately arrived safely at the space station, these unexpected hurdles have prompted NASA to take a closer look at starliners systems. As a result of these ongoing evaluations, NASA has had to make some adjustments to its crude flight schedule. The two CFT astronauts, Butch Wilmore and Sunny Williams, who are currently aboard the ISS, have been reassigned to return to Earth on a SpaceX Crew Dragon capsule in February twenty twenty five. NASA emphasizes that they're committed to providing more information as it becomes available. Agency is working diligently with Boeing to address these challenges and ensure that Starliner meets all necessary safety and performance standards before its next crude mission. For now, the space community watches and waits as NASA and Boeing continue their rigorous review process, and that brings us to the end of today's journey through the cosmos.
