    SpaceTime with Stuart Gary Gary - Series 29 Episode 25
    In this episode of SpaceTime, we explore the intriguing mysteries of Mars' gullies, uncover a unique inside-out planetary system, and witness the inaugural launch of Europe's most powerful rocket.
    Mysterious Martian Gullies Explained
    Scientists have made significant strides in understanding the enigmatic gullies on Mars, previously thought to be shaped by unknown forces. A new study published in Geophysical Research Letters reveals that blocks of frozen carbon dioxide are the culprits behind these formations. When the Martian winter sets in, CO2 ice accumulates and, upon warming, sublimates, creating gas pressure that carves deep gullies in the Martian surface. This groundbreaking phenomenon, likened to the sandworms of Dune, showcases a unique geological process not observed on Earth.
    Inside-Out Planetary System Discovery
    Astronomers have identified a remarkable new planetary system, catalogued as LHS 1903, that defies conventional models of planetary formation. Unlike our solar system, which features rocky planets close to the star and gas giants further out, LHS 1903 has a small rocky planet orbiting outside of two gas giants. This discovery, detailed in Science, suggests that this rocky world may have formed in a gas-depleted environment, challenging existing theories about how planets evolve and raising questions about the nature of planetary systems.
    Europe's Powerful Rocket Launch
    The European Space Agency has successfully launched the Ariane 64, its most powerful rocket to date, from the Kourou Spaceport in French Guiana. This inaugural mission, VA267, carried 32 satellites into orbit for Amazon's LEO network, marking a significant milestone as the largest number of satellites ever launched by an Ariane rocket. With plans for an average of 10 launches per year, the Ariane 64 is set to play a crucial role in the future of satellite deployment.

    In this episode of SpaceTime, we uncover astonishing discoveries about the birth of black holes, a revolutionary Martian navigation system, and the arrival of NASA's SpaceX Crew 12 at the International Space Station.
    The Birth of a Black Hole: A New Perspective
    Astronomers have made a groundbreaking discovery by observing a star in the Andromeda Galaxy collapsing into a black hole without the expected supernova explosion. The star, catalogued as M31 2014 DS1, was seen glowing brightly in infrared light before fading away, leaving behind a dust shell. This event, which had been anticipated for decades, suggests that massive stars may collapse directly into black holes, challenging long-held assumptions about stellar deaths. The findings, published in the journal Science, provide new insights into the processes that govern black hole formation and indicate that such direct collapses may be more common than previously thought.
    NASA's New Martian Navigation System
    NASA has introduced an innovative navigation system for its Perseverance rover, allowing it to determine its location on Mars with remarkable precision—within 25 centimeters. The new technology, called Mars Global Localization, enables the rover to autonomously compare panoramic images with orbital terrain maps, eliminating the need for Earth-based assistance. This advancement significantly enhances the rover's ability to explore the Martian surface independently, paving the way for more extensive scientific investigations.
    SpaceX Crew 12 Arrives at the ISS
    NASA's SpaceX Crew 12 has successfully docked with the International Space Station, restoring the crew complement to seven members. The mission includes a diverse crew of two Americans, a Russian, and a French astronaut, who will conduct approximately 250 scientific experiments in orbit. Additionally, NASA has approved a sixth private mission to the ISS, slated for next year, which aims to support new research initiatives and infrastructure development for future human spaceflight missions.

    SpaceTime with Stuart Gary Gary - Series 29 Episode 23
    In this episode of SpaceTime, we investigate the discovery of a nearly invisible galaxy dominated by dark matter, the latest delays in the Artemis 2 mission to the Moon, and the anticipated launch of Australia's new hypersonic scramjet.
    A Dark Matter Galaxy Unveiled
    Astronomers have identified an almost invisible galaxy, catalogued as CDG2, located in the Perseus galaxy cluster approximately 300 million light years away. This galaxy is believed to be composed of about 99% dark matter, making it one of the most dark matter-dominated galaxies ever detected. The findings, published in Astrophysical Research Letters, reveal that dark matter constitutes roughly 80% of the universe's total matter, and CDG2's faint presence was confirmed through observations of its globular clusters using NASA's Hubble Space Telescope and the European Space Agency's Euclid Space Observatory.
    Artemis 2 Mission Delayed Again
    NASA has announced another delay for the Artemis 2 mission, which aims to return humans to lunar orbit for the first time in over 50 years. A helium leak discovered in the Space Launch System (SLS) rocket's upper stage has prompted the agency to roll back the launch vehicle to the vehicle assembly building for repairs. This setback eliminates the potential for a March launch, with the next available windows opening in early April. The Artemis 2 mission will carry a crew of four on a 10-day journey to the Moon, including critical system tests and satellite deployments.
    Australia's Hypersonic Scramjet Launch Imminent
    An Australian company is set to test its new hypersonic scramjet-powered aircraft, the Dart AE, before the end of the month. This innovative vehicle will utilize a 3D printed Spartan Scramjet engine, designed to operate at speeds exceeding Mach 5 with liquid hydrogen fuel. The mission, codenamed Cassowary Vex, will launch aboard a Rocket Lab electron rocket and aims to validate the scramjet propulsion system under real hypersonic flight conditions while producing zero carbon emissions.
