Hey, welcome to Fascinating Frontiers, episode sixty. Today is April thirtieth, twenty twenty-six. Let's look at what's new across the frontiers of space and science. A Falcon Heavy is rolling toward the pad for its first launch in 18 months while Europe prepares Ariane 6’s second flight with four boosters. Space X just completed back-to-back launches of a Falcon Heavy and a Falcon 9. Both side boosters from the Heavy came back to Earth and landed safely at Landing Zones 2 and 40. This marks the vehicle's return after a year and a half hiatus. The successful landings prove that rapid reusability still works even for these heavy-lift missions. From an engineering perspective it is impressive to see the same hardware fly again so reliably after that long gap. The precision required to bring those boosters down on target speaks to how mature the recovery systems have become. Now while the Heavy was making headlines on the East Coast another Falcon 9 was busy expanding the biggest satellite constellation on the planet. A Falcon 9 launched from California and successfully deployed its full complement of 24 Starlink satellites into orbit. This keeps the constellation growing at a steady pace. It also demonstrates the reliability of the workhorse rocket on dedicated rideshare-class missions. You can see how Space X has turned this vehicle into a true utility player that can handle both crewed flights and these smaller dedicated launches. Every new batch like this one strengthens the network that so many people now rely on for internet access from almost anywhere on Earth. Speaking of things headed toward the Moon one piece of Space X hardware has an unusual destination coming up in a few months. You know what is fascinating about this. An expended Falcon 9 upper stage is now on a trajectory that will cause it to strike the Moon in August. The deliberate crash will happen at roughly 2.5 kilometres per second. That impact will release energy equivalent to a few hundred kilograms of TNT and send pressure waves rippling through solid rock. Seismometers placed by earlier landers will detect those waves from hundreds of kilometres away. Because we know the exact mass speed and impact angle the event becomes a precisely calibrated probe of the Moon’s crust and mantle. The really wild part is that the Moon rings like a bell for up to an hour after even a modest strike. It reveals layering we still do not fully understand. We can watch the flash from orbit measure the seismic coda from the surface and compare both to computer models. Yet one specific mystery refuses to yield. Why do some lunar impact sites show unexpectedly deep fracturing while others appear to heal far faster than rock physics predicts. That single unanswered detail sits at the heart of how the Moon’s interior has evolved over billions of years. From an artificial impact on the Moon to a very real new rocket preparing to leave Earth Europe is about to fly its most powerful launcher again. Europe’s most powerful rocket Ariane 6 is set for its second flight with four solid boosters. The launch is scheduled between nine oh eight A Mand nine fifty-seven A MBritish Summer Time on April 30 2026. This mission continues the launcher’s early operational campaign. It also expands Europe’s independent heavy-lift capability at a time when reliable access to space matters more than ever. Having a homegrown heavy rocket that can fly on its own schedule strengthens the continent’s position in the growing international space economy. While new rockets grab the spotlight a veteran astronaut with a unique medical background is getting ready for his first trip to orbit. Anil Menon a former Space X flight surgeon and member of nassa’s 2021 astronaut class will make his first trip to space. His mission launches on 14 July. He will head to the International Space Station. His background in aerospace medicine brings unique operational insight to long-duration expeditions. Having a doctor-astronaut who already understands the spacecraft systems from the operator side should prove valuable during what could be an extended stay. It is always reassuring when the crew includes someone who has lived and breathed the medical side of human spaceflight for years. From the human side of spaceflight let us swing over to what you can actually see with your own eyes this month. This month the Big and Little Dippers are riding high in the northern evening sky. All five bright planets are visible right now. The Eta Aquariid meteors from Halley’s Comet are also active. Sky and Telescope has put together a complete backyard guide that helps observers make the most of these sights. Even if you only have a few minutes after dark you can step outside spot the dippers trace the planets and maybe catch a meteor or two. It is a great time to reconnect with the sky without any special equipment. While we are looking up powerful telescopes are still revealing distant galaxies. nassa’s Hubble Space Telescope imaged the luminous barred spiral galaxy IC 486. The image was captured on April thirteenth, twenty twenty-six. It reveals the galaxy’s soft glow against the blackness of space. You can clearly see the graceful spiral arms and the stellar populations that trace them. It is a classic example of the structures that build the universe we see today. Every new Hubble portrait like this one reminds me how beautiful and orderly spiral galaxies can look from millions of light-years away. From galaxies millions of light-years away we come back to our own cosmic neighbourhood and a dramatic event from a thousand years ago. On April thirtieth, ten six the brightest supernova in recorded human history flared in the constellation Lupus. It reached 16 times the brightness of Venus. The event was visible across China Japan the Middle East and Europe. It was reportedly bright enough to read by at night. Some researchers think it may even appear in North American rock art. That supernova was a reminder of how dynamic the cosmos can be and how profoundly those events must have affected people who witnessed them without any modern context. While lawmakers debate future rockets the current Artemis crew recently received some high-profile encouragement. President Trump welcomed the Artemis II crew to the White House. The event celebrated the upcoming crewed lunar flyby mission. It underscored continued high-level political support for nassa’s return to the Moon. Seeing the crew recognized at that level helps keep public attention focused on the mission that will send humans beyond low Earth orbit for the first time in decades. Political support is important but so is the technology that will let future explorers survive on the lunar surface. Engineers have created hair-thin nanotube shielding that can be 3D-printed directly onto electronics and solar panels. Picture a fleet of autonomous rovers trundling across the lunar south pole three kilometres from base when a solar storm alert suddenly lights up mission control. Instead of scrambling to retrieve them engineers can simply rely on these lightweight layers. The shielding adds almost no mass yet it is flexible enough to survive the extreme temperature swings and vibration of launch. Early tests suggest it can deflect the worst of the high-energy particles that would otherwise fry unshielded systems. What comes next is flight qualification on actual lunar hardware. That could open the door to long-duration robotic missions in permanently shadowed regions. One question remains how will these nanotube layers hold up after years of micrometeorite sandblasting and relentless UV exposure on the Moon. Protecting hardware is one thing sometimes you have to cancel hardware entirely. The Canadian Space Agency terminated last year’s contract with Spire Global to build a fleet of small satellites dedicated to monitoring wildfires. The decision ends one planned contribution to Canada’s Earth-observation capabilities. It is never easy to cancel a project especially one aimed at something as important as wildfire tracking. Still these kinds of adjustments happen as budgets and priorities shift across government space programs. On a brighter note new materials and clever ideas are still moving forward at nassa. Al Nash from the Jet Propulsion Laboratory spoke on moving interesting ideas to selected ASTRA studies. The seminar took place on 30 April. It explored considerations for advancing early-stage astrophysics technology concepts. Hearing how JPL thinks about turning promising ideas into funded studies gives a glimpse into the careful filtering process that shapes future missions. While we push new tech Earth itself keeps putting on quite a show. As winter gave way to spring distinct cloud patterns formed textbook examples of various atmospheric phenomena over the Gulf of Alaska. Satellite imagery captured the transition and the dynamic weather systems shaping Earth’s high-latitude skies. The images are a beautiful reminder that even from orbit our own planet can look every bit as dramatic as anything we see in deep space. Before we go keep an eye on how that upcoming lunar impact in August unfolds because the seismic data could reshape what we think we know about the Moon’s interior.
