Speaker 1: Welcome to Astronomy Daily. I'm anna, and today we have
Speaker 1: an incredible lineup of stories that showcase the cutting edge
Speaker 1: of space exploration and astronomical discoveries. We'll dive into a
Speaker 1: fascinating breakthrough regarding the mysterious dark matter in our galaxy's
Speaker 1: GD one stellar stream, explore China's ambitious testing of multiple
Speaker 1: rocket engines, and catch up with NASA's Artemus one Oriyan
Speaker 1: spacecraft as it returns home to Kennedy Space Center. We'll
Speaker 1: also look at SpaceX's upcoming launch of not one, but
Speaker 1: two private lunar landers, and discover how NASA is developing
Speaker 1: new radiation resistant computers to handle the harsh environment of space.
Speaker 1: It's a packed show that highlights just how quickly space
Speaker 1: technology and our understanding of the Cosmos continue to evolve.
Speaker 1: So let's get started. Let's kick the news off today
Speaker 1: with a quick update. Blue Origin, the space venture founded
Speaker 1: by Jeff Bezos, has postponed the inaugural flight of its
Speaker 1: new Glen rocket. The launch, initially set for early Monday
Speaker 1: morning at CAIS sape Canaveral, faced multiple delays due to
Speaker 1: technical issues and unfavorable weather conditions. An icing problem in
Speaker 1: a purge line crucial for the rocket's hydraulic systems was
Speaker 1: identified during the countdown. This, combined with high seas affecting
Speaker 1: the booster's planned ocean landing, led to the decision to
Speaker 1: stand down. The company now aims for a potential launch
Speaker 1: on Thursday, with a three hour window starting at one
Speaker 1: a m Eastern time. Standing at three hundred and twenty feet,
Speaker 1: the new Glen rocket is named in honor of astronaut
Speaker 1: John Glenn. It's designed to carry heavy payloads and features
Speaker 1: a reusable first stage booster, marking a significant step forward
Speaker 1: in Blue Origin's mission to make space travel more sustainable
Speaker 1: and cost effective. This mission, dubbed NNG one, is set
Speaker 1: to carry a prototype of the Blue Ring spacecraft, intended
Speaker 1: for future deep space missions. A successful launch would position
Speaker 1: Blue Origin as a formidable competitor in the commercial space sector,
Speaker 1: challenging the dominance of Elon Musk's SpaceX. While the delay
Speaker 1: is undoubtedly a setback, it's a reminder of the complexities
Speaker 1: involved in space exploration. Each challenge presents an opportunity for
Speaker 1: growth and innovation. As Jeff Bezos himself has emphasized gratitem
Speaker 1: ferocit step by step ferociously will keep you updated on
Speaker 1: Blue origins, progress and the rescheduled launch. Astronomers may have
Speaker 1: finally cracked a long standing cosmic mystery about one of
Speaker 1: our galaxy's most intriguing features, the GD one stellar stream.
Speaker 1: This ribbon like structure of stars, which stretches across our
Speaker 1: galaxies halo, has puzzled scientists for years due to its
Speaker 1: unusual patterns of gaps and spurs that seem to defy
Speaker 1: conventional explanations. A team led by researchers at the University
Speaker 1: of California Riverside has proposed an exciting solution involving dark matter,
Speaker 1: but not just any dark matter. Their research suggests these
Speaker 1: distinctive features were created by what's called a self interacting
Speaker 1: dark matter sub halo, a dense concentration of dark matter
Speaker 1: that behaves differently than the traditional cold dark matter model
Speaker 1: we're familiar with. What makes this discovery particularly fascinating is
Speaker 1: that the density needed to create these unusual patterns in
Speaker 1: GD one is much higher than what we'd expect from
Speaker 1: conventional dark matter theories. The research team found that only
Speaker 1: a collapsing subhilo of self interacting dark matter could achieve
Speaker 1: the necessary density to produce these distinctive features we observe.
Speaker 1: This isn't just about solving one mysterious structure in our galaxy.
Speaker 1: If confirmed, these findings could fundamentally change our understanding of
Speaker 1: dark matter itself. Remember, dark matter makes up about eighty
Speaker 1: five percent of all matter in the universe, yet we
Speaker 1: still know remarkably little about its true nature. This research
Speaker 1: suggests that dark matter particles might interact with each other
Speaker 1: through a new kind of force, rather than being completely
Speaker 1: invisible to one another as previously thought. The team used
Speaker 1: sophisticated computer simulations to model how this sell interacting dark
Speaker 1: matter would behave, and the results matched perfectly with the
Speaker 1: observed features in the GD one stream. It's like finding
Speaker 1: the missing piece of a puzzle that's been sitting on
Speaker 1: the table for years, suddenly revealing a whole new picture
Speaker 1: of how our galaxy works. What's particularly exciting about this
Speaker 1: discovery is that it opens up new ways to study
Speaker 1: dark matter. By looking at stellar streams like GD one,
Speaker 1: we might be able to better understand not just where
Speaker 1: dark matter is, but how it behaves and interacts with itself,
Speaker 1: something that could revolutionize our understanding of the universe's fundamental structure. Next,
Speaker 1: a little mystery from China that has set the space
Speaker 1: community buzzing. In a remarkable display of technological advancement, China's
Speaker 1: space program has taken a significant leap forward, conducting tests
Speaker 1: of five different rocket engines all in a single day.
Speaker 1: The China Aerospace Science and Technology Corporation or CASSI, carried
Speaker 1: out these tests at two separate locations, beij and Laiwan
Speaker 1: County in Hebei Province. One of the most notable tests
Speaker 1: involved a new hydrogen oxygen engine designed for upper stage rockets.
Speaker 1: During its one hundred second test, firing, engineers gathered crucial
Speaker 1: performance data that could pave the way for future missions.
Speaker 1: This wasn't just any routine test. It's believed to be
Speaker 1: connected to China's ambitious plans for crude lunar missions, specifically
Speaker 1: their long March tenth launcher program. But that's not all
Speaker 1: that was tested that day. In Beijing, engineers put three
Speaker 1: different engines through their paces, a main engine, an upper
Speaker 1: stage engine, and a reaction in orbit control engine. While
Speaker 1: specific details about which rockets these engines are destined for
Speaker 1: remain under wraps, it's clear that China is developing multiple
Speaker 1: launch capabilities simultaneously. Perhaps most intriguingly, the testing day included
Speaker 1: a methane liquid oxygen engine at the Laiuan facility. This
Speaker 1: type of engine represents the cutting edge of rocket technology,
Speaker 1: with several Chinese companies already developing similar systems. It's worth
Speaker 1: noting that Cassie is working on a particularly powerful version
Speaker 1: for their long March ninth Mega rocket project. These tests
Speaker 1: signal China's commitment to developing a diverse range of rocket technologies,
Speaker 1: from deep space exploration vehicles to heavy lift rockets. According
Speaker 1: to KSC engineers, this is just the beginning. They're planning
Speaker 1: to conduct even more research and testing of various engine
Speaker 1: types for China's major space projects, suggesting we might see
Speaker 1: several new Chinese rockets debut in the coming year. This
Speaker 1: coordinated testing effort demonstrates China's growing capabilities in space technology
Speaker 1: and their determination to become a major player in space exploration.
Speaker 1: With these successful tests, they're laying the groundwork for increasingly
Speaker 1: ambitious missions, from lunar exploration to potential Mars voyages. Meanwhile,
Speaker 1: back in the States, the Artemis Ones Orion spacecraft has
Speaker 1: made its way back to Kennedy Space Center after completing
Speaker 1: an extensive eleven month testing campaign in Ohio. Now designated
Speaker 1: as the Orion Environmental Test Article or ETA, this spacecraft
Speaker 1: has already proven its worth during its historic journey around
Speaker 1: the Moon, but its mission to advance space exploration is
Speaker 1: far from over. After splashing down in the Pacific Ocean
Speaker 1: following its lunar adventure, the spacecraft was transported across the
Speaker 1: country to Florida, where it underwent its first round of modifications.
Speaker 1: But it was at NASA's Neil Armstrong Test Facility in Sandusky, Ohio,
Speaker 1: where the real intensive testing took place, preparing it for
Speaker 1: even more challenging future missions. Now back at Kennedy's Multi
Speaker 1: Payload Processing Facility, engineers are gearing up for a crucial
Speaker 1: series of tests focusing on the spacecraft's propulsion systems. Of
Speaker 1: particular interest are the twelve reaction control system thrusters, which
Speaker 1: will undergo simulated hot fire testing. These thrusters are absolutely
Speaker 1: vital for controlling the spacecraft's rotation during orbit, re entry,
Speaker 1: and potential abort scenarios. But the testing doesn't stop there.
Speaker 1: The spacecraft will soon make its way to Kennedy's Space
Speaker 1: system's processing facility for acoustic noise demonstration tests. These evaluations
Speaker 1: are crucial for improving future acoustic testing procedures, benefiting both
Speaker 1: NASA and their primary contractor, Lockheed Martin. Perhaps most intriguingly,
Speaker 1: teams will be carefully removing certain pieces of hardware from
Speaker 1: the ETA for reusability studies. The knowledge gained from examining
Speaker 1: these components could prove invaluable for future Artemis missions as
Speaker 1: NASA continues its ambitious plans to establish a sustainable human
Speaker 1: presence on the Moon and eventually venture to Mars. This
Speaker 1: methodical testing and evaluation process demonstrates NASA's commitment to ensuring
Speaker 1: the safety and success of future deep space missions and
Speaker 1: not to be left behind. In an exciting development for
Speaker 1: lunar exploration, SpaceX is preparing to launch two private lunar
Speaker 1: landers aboard a single Falcon nine rocket from NASA's Kennedy
Speaker 1: Space Center. The launch window opens early Wednesday morning at
Speaker 1: one eleven a m Eastern time, marking what promises to
Speaker 1: be a busy year of missions to the Moon. The
Speaker 1: two spacecraft sharing this historic ride are Firefly Aerospace's Blue
Speaker 1: Ghost Mission IE and IE space is Resilience lander. Blue Ghost,
Speaker 1: part of NASA's Commercial Lunar Payload Services program, will carry
Speaker 1: scientific instruments to the lunar surface, while Resilience represents IE
Speaker 1: space's second attempt at achieving a successful moon landing. These
Speaker 1: missions will follow distinctly different trajectories. After separation from the
Speaker 1: Falcon nine, blue Ghost will spend about twenty five days
Speaker 1: in Earth orbit before initiating its journey to the Moon.
Speaker 1: After another twenty days, including four days of transit and
Speaker 1: sixteen days in lunar orbit, it will attempt to touch
Speaker 1: down in Merrichrisium, the Sea of Crises. Once on the surface,
Speaker 1: it will conduct two weeks of scientific operations before capturing
Speaker 1: one final dramatic image of the lunar sunset. Resilience, on
Speaker 1: the other hand, will take a more gradual approach, spending
Speaker 1: four to five months reaching its destination. This extended timeline
Speaker 1: reflects lessons learned from Icepace's first mission, which reached lunar
Speaker 1: orbit but unfortunately crashed during its landing attempt last April.
Speaker 1: The spacecraft features significant upgrades to both hardware and software,
Speaker 1: aiming to succeed where its predecessor fell short. The mission's
Speaker 1: target is Mare Frigoris, the Sea of Cold in the
Speaker 1: Moon's northern hemisphere. There, it will deploy a small rover
Speaker 1: named Tenacius, which will collect lunar dust samples as part
Speaker 1: of a NASA contract. This careful, milestone based approach demonstrates
Speaker 1: I Space's commitment to achieving the first successful private Japanese
Speaker 1: landing on the Moon. These launches kick off what promises
Speaker 1: to be an extraordinarily active year for lunar exploration, with
Speaker 1: multiple missions planned by various companies and space agencies. From
Speaker 1: Intuitive Machines upcoming IM two mission to Blue Origins development
Speaker 1: of their lunar lander. We're witnessing the dawn of a
Speaker 1: new era in commercial lunar exploration. Computers have become absolutely
Speaker 1: essential for space exploration, but they face a serious challenge
Speaker 1: that we don't have to worry about here on Earth. Radiation.
Speaker 1: While our planet's magnetic field and atmosphere protect our electronics
Speaker 1: from harmful radiation, spacecraft computers have to cope with direct
Speaker 1: exposure to high energy particles from the Sun and cosmic rays.
Speaker 1: The effects can be severe. Even a single blast of
Speaker 1: radiation can cause what scientists call a single event effect,
Speaker 1: potentially corrupting data or causing system crashes that could jeopardize
Speaker 1: entire missions. That's why NASA is now testing an innovative solution,
Speaker 1: the Radiation Tolerant Computer, or RATYPC for short. This remarkable
Speaker 1: piece of technology is scheduled for its first real world
Speaker 1: test aboard the upcoming Blue Ghost lunar mission. What makes
Speaker 1: the rad PC special is its ability to monitor and
Speaker 1: repair itself in real time. It uses special processors called
Speaker 1: programmable gait arrays that can detect when they've been struck
Speaker 1: by radiation and automatically fix any damage without interrupting normal operations.
Speaker 1: The system also includes radiation sensors or docimeters that will
Speaker 1: continuously measure radiation levels during the journey to the moon.
Speaker 1: This will provide valuable data about how radiation levels change
Speaker 1: as spacecraft move through Earth's magnetosphere and into deep space,
Speaker 1: as well as detailed information about radiation conditions at the
Speaker 1: landing site. If successful, the rad PC could revolutionize space computing.
Speaker 1: Its self healing capabilities could make future spacecraft computers far
Speaker 1: more resilient and reliable, especially for long duration missions where
Speaker 1: radiation exposure is inevitable. This kind of advancement is crucial
Speaker 1: as we push further into space, whether it's establishing a
Speaker 1: permanent presence on the Moon or eventually sending humans to Mars.
Speaker 1: And that brings us to the end of today's episode
