Speaker 1: Welcome to Bedtime Astronomy. Explore the wonders of the cosmos
Speaker 1: with our soothing Bedtime Astronomi podcast. Each episode offers a
Speaker 1: gentle journey through the stars, planets, and beyond, perfect for
Speaker 1: unwinding after a long day. Let's travel through the mysteries
Speaker 1: of the universe as you drift off into a peaceful
Speaker 1: slumber under the night sky. Moon's far side hold secrets.
Speaker 1: China's mission uncovers ancient volcanic activity. On November fifteenth, twenty
Speaker 1: twenty four, a new chapter unfolded in our understanding of
Speaker 1: the Moon. A research paper published in the prestigious journal
Speaker 1: Science detailed the analysis of lunar samples retrieved by China's
Speaker 1: Chinese six mission, which landed on the far side of
Speaker 1: the Moon in an area known as the South Pole
Speaker 1: Aitkan Basina. The samples, composed primarily of basalt rock, offered
Speaker 1: a glimpse into the Moon's volcanic history and challenged existing
Speaker 1: theories about lunar geology. The Moon's surface has long captivated
Speaker 1: scientists with its stark dichotomy. The near side, the face
Speaker 1: that perpetually faces Earth, is dominated by vast, dark plains
Speaker 1: of basaltic rock solidified lava flows from ancient eruptions. In contrast,
Speaker 1: the far side, forever hidden from our view, appears more
Speaker 1: rugged and displays less evidence of volcanic activity. This difference
Speaker 1: has fueled scientific curiosity for decades, prompting missions to collect
Speaker 1: samples and unravel the Moon's geological story. The Changi six
Speaker 1: mission specific targeted the SPA, a massive impact basin, believed
Speaker 1: to be the oldest and largest on the Moon. By
Speaker 1: analyzing the composition of the retrieved basalt samples, Professor Suedoan's
Speaker 1: team from the Guangzhou Institute of Geochemistry at the Chinese
Speaker 1: Academy of Sciences aimed to shed light on the volcanic
Speaker 1: processes that shape the Moon's far side. These findings from
Speaker 1: the Chinese six mission hold significant implications for our understanding
Speaker 1: of the Moon's formation and evolution. The identification of VLT
Speaker 1: basalt suggests that the far side may have experienced a
Speaker 1: different type of volcanic activity compared to the near side.
Speaker 1: This could be due to variations in the Moon's internal
Speaker 1: structure or the nature of the impacts that form the
Speaker 1: SPA basin. Furthermore, the consistent age of the basalts regardless
Speaker 1: of their titanium content suggests a period of widespread lunar
Speaker 1: volcanic activity around two point eight three billion years ago.
Speaker 1: This period may have been triggered by a specific event,
Speaker 1: such as a large impact or internal heating within the Moon.
Speaker 1: B Changi six mission's success paves the way for further
Speaker 1: lunar exploration and analysis. By studying samples from diverse locations
Speaker 1: on the Moon, scientists can build a more complete picture
Speaker 1: of our celestial neighbour's geological past. This knowledge is crucial
Speaker 1: not only for understanding the Moon's formation, but also for
Speaker 1: informing future missions that aim to establish a permanent human
Speaker 1: presence on the lunar surface. Harnessing Uranus hidden heat a
Speaker 1: novel approach to solar power in the outer Solar System.
Speaker 1: A research team led by doctor Secret Reganda from the
Speaker 1: University of California, Berkeley has published a groundbreaking study in
Speaker 1: the journal Nature Energy proposing a novel approach to harnessing
Speaker 1: solar power on a celestial body far beyond Earth, Urinus.
Speaker 1: This proposition might seem counterintuitive at first glance. Uranus, the
Speaker 1: seventh planet from the Sun, resides in the distant reaches
Speaker 1: of our solar system bathed in a faint one sunlight
Speaker 1: compared to the warmth we experience on Earth. However, doctor
Speaker 1: Reganda and his colleagues argue that urinus unique atmospheric properties
Speaker 1: present a hidden opportunity for capturing solar energy. The key
Speaker 1: lies in urinus thermosphere, the outermost layer of its atmosphere.
Speaker 1: Unlike Earth's thermosphere, which is heated by solar radiation, causing
Speaker 1: temperatures to rise with altitude, urinus thermosphere exhibits a peculiar behavior.
Speaker 1: Despite receiving significantly less sunlight, its temperature remains surprisingly high,
Speaker 1: reaching a scorching eight hundred degrees celsius one thousand, four
Speaker 1: hundred and seventy two degrees fahrenheit at its peak. This
Speaker 1: anomaly can be attributed to a complex interplay of factors.
Speaker 1: Sunlight interacts with hydrogen molecules in the upper atmosphere, breaking
Speaker 1: them apart into free hydrogen atoms. These free hydrogen atoms
Speaker 1: then absorb the Sun's ultraviolet radiation, becoming energized and releasing
Speaker 1: energy in the form of heat. This process meln as
Speaker 1: thermospheric heating creates a surprisingly hot layer despite the diminished sunlight,
Speaker 1: reaching Uranus do. Doctor Reganda's team proposes utilizing this unexpected
Speaker 1: warmth to generate electricity. Their concept involves deploying a network
Speaker 1: of tethered balloons into the Uranian thermosphere. These balloons would
Speaker 1: function as heat exchangers, absorbing the thermal energy from the
Speaker 1: surrounding atmosphere. The captured heat would then be converted into
Speaker 1: electricity using thermal electric generators, a technology that utilizes the
Speaker 1: temperature difference between a hot and cold source to produce electricity.
Speaker 1: The generated electricity could be used to power various scientific
Speaker 1: instruments on Uranus itself, such as probes or atmospheric monitoring stations. Alternatively,
Speaker 1: with further technological advancements, the captured energy could potentially be
Speaker 1: beamed back to Earth using powerful microwave transmitters, Although this
Speaker 1: presents significant technological hurdles. The prospect of harnessing solar power
Speaker 1: on Urinus raises several intriguing questions. The harsh environment of
Speaker 1: the Uranian thermosphere, characterized by extreme temperatures and potentially strong winds,
Speaker 1: poses significant engineering challenges for the tethered balloons and the
Speaker 1: energy conversion systems. Additionally, the efficiency of converting thermal energy
Speaker 1: from the thermosphere into usable electricity, needs further research. Despite these challenges,
Speaker 1: doctor Reganda's team believes this concept holds immense potential. Urinous
Speaker 1: vast thermosphere offers a virtually limitless source of energy, and
Speaker 1: the success of such a venture could revolutionize our understanding
Speaker 1: of harvesting solar power in unconventional environments within our solar system.
Speaker 1: This research paves the way for further exploration of urinous
Speaker 1: unique atmospheric properties and opens doors to innovative solutions for
Speaker 1: powering future space missions. Venturing beyond the inner Solar system.
Speaker 1: Building with the Moon, China tests bricks made from lunar soil.
Speaker 1: China is taking a giant leap towards establishing a permanent
Speaker 1: presence on the Moon in a bold experiment bear testing
Speaker 1: the feasibility of using lunar soil itself as a building
Speaker 1: material for future lunar bases. This innovative approach could revolutionize
Speaker 1: lunar construction, eliminating the need to transport vast quantities of
Speaker 1: materials from Earth. The harsh lunar environment poses significant challenges
Speaker 1: for construction. Extreme temperature fluctuations, micrometeoroid bombardment, and intense radiation
Speaker 1: requires structures with exceptional durability. Traditionally, building materials would need
Speaker 1: to be transported from Earth, a costly and resource intensive endeavour.
Speaker 1: Scientists at a university in Wuhan, China, have developed a
Speaker 1: solution bricks made from simulated lunar soil. This simulated soil
Speaker 1: replicates the composition of the actual lunar regolith, the loose
Speaker 1: dust they layer that covers the Moon's surface. By mimicking
Speaker 1: the real material, researchers can assess its suitability for construction
Speaker 1: under lunar conditions. These prototype bricks are formed from various
Speaker 1: Earth based materials such as basalt, chosen for their strength
Speaker 1: and resemblance to lunar soil components. The manufacturing process involves
Speaker 1: binding these materials together, potentially using techniques like three D
Speaker 1: printing or traditional brickmaking methods. The success of this experiment
Speaker 1: hinges on the brick's ability to withstand the harsh lunar environment.
Speaker 1: China plans to launch this initial test to the Moon
Speaker 1: emissions around twenty twenty eight, likely involving the Chang E
Speaker 1: eight lunar lander and rover. These bricks will be exposed
Speaker 1: to the lunar environment for several allowing scientists to monitor
Speaker 1: their structural integrity and resilience to radiation and temperature extremes.
Speaker 1: If the tests prove successful, the implications are far reaching.
Speaker 1: Using lunar soil for construction would significantly reduce the logistical
Speaker 1: and financial burden of establishing a lunar base. It would
Speaker 1: eliminate the need for massive launches carrying building materials from Earth,
Speaker 1: allowing for a more sustainable and cost effective approach to
Speaker 1: lunar development. This experiment not only paves the way for
Speaker 1: future lunar bases, but also opens doors for insider resource
Speaker 1: utilization isru on other celestial bodies. By learning to utilize
Speaker 1: resources readily available on location, we can pave the way
Speaker 1: for a future of sustainable exploration and habitation beyond Earth.
