0:00 Speaker 1: Welcome to Astronomy Daily, your source for the latest space

0:02 Speaker 1: in astronomy news. I'm your host, Anna, and we've got

0:05 Speaker 1: an exciting episode lined up for you Today. We'll be

0:08 Speaker 1: exploring some fascinating developments in the world of space and

0:11 Speaker 1: astronomy that are sure to captivate your imagination. From a

0:15 Speaker 1: potentially dazzling commet that could light up our night sky

0:18 Speaker 1: to innovative facilities preparing astronauts for lunar missions, we've got

0:23 Speaker 1: it all covered. We'll also dive into groundbreaking research that's

0:26 Speaker 1: pushing the boundaries of our understanding of life in the cosmos,

0:29 Speaker 1: and revolutionary propulsion technology that could take us further into

0:32 Speaker 1: space than ever before. So strap in and get ready

0:36 Speaker 1: for a cosmic journey through the latest and most intriguing

0:38 Speaker 1: stories from the final Frontier. Let's blast off into today's

0:42 Speaker 1: episode of Astronomy Daily. Get ready for a celestial spectacle

0:46 Speaker 1: that could light up our night sky this fall. In

0:48 Speaker 1: the Northern Hemisphere, astronomers are eagerly tracking Commet C twenty

0:53 Speaker 1: twenty three, A three, also known as comet suchinshan Atlas,

0:57 Speaker 1: which has the potential to shine as brightly as the

0:59 Speaker 1: North Star. This cosmic visitor hails from the distant Ort Cloud,

1:03 Speaker 1: a region at the outer edges of our Solar system.

1:05 Speaker 1: Discovered in early twenty twenty three by observatories in South

1:08 Speaker 1: Africa and China, Comet A three has captured the attention

1:12 Speaker 1: of both professional astronomers and space enthusiasts worldwide. What makes

1:17 Speaker 1: this commet so special well. According to models developed by

1:20 Speaker 1: researchers at the Seti Institute, Comet A three could become

1:24 Speaker 1: one of the brightest objects visible in the northern Hemisphere

1:27 Speaker 1: this autumn. If it survives its close encounter with the

1:30 Speaker 1: Sun on September twenty seventh, we might be in for

1:33 Speaker 1: a treat rivaling the spectacular comet McNaught of two thousand

1:37 Speaker 1: and seven. But there's still much to learn about this

1:40 Speaker 1: celestial wanderer. After an unexpected period of dimming, the comet

1:44 Speaker 1: appears to be regaining its brightness. Scientists are considering various explanations,

1:49 Speaker 1: including possible fragmentation of the comet or effects related to

1:52 Speaker 1: its viewing angle from Earth. The Unistellar Community, a network

1:56 Speaker 1: of citizen scientists, is actively contributing to our understanding of

1:59 Speaker 1: COMT A three. Over twenty five thousand users are tracking

2:03 Speaker 1: its progress, helping to refine predictions about its behavior as

2:06 Speaker 1: it approaches the inner Solar system, whether Comet A three

2:09 Speaker 1: puts on the show of the decade or fizzles out.

2:12 Speaker 1: Its approach offers a unique opportunity for both professional and

2:16 Speaker 1: amateur astronomers to study the dynamics of these fascinating objects

2:21 Speaker 1: from the outer reaches of our solar system. Next, let's

2:25 Speaker 1: take a look at a similar problem in how two

2:27 Speaker 1: different agencies around the globe are solving it astronaut training

2:30 Speaker 1: in situ. The European Space Agency and German Aerospace Center

2:34 Speaker 1: have taken a giant leap in lunar mission preparation with

2:37 Speaker 1: their new facility called Luna, located near Cologne, Germany. This

2:42 Speaker 1: innovative lunar analog aims to recreate the Moon's surface right

2:45 Speaker 1: here on Earth, providing a crucial training ground for future astronauts.

2:50 Speaker 1: Luna's main feature is a massive seven hundred square meter

2:53 Speaker 1: hall filled with about nine hundred tons of simulated lunar regalith.

2:57 Speaker 1: This material, known as eac one, is derived from volcanic

3:01 Speaker 1: powder found in Germany's Eiffel region. It closely mimics the fine,

3:05 Speaker 1: dusty surface astronauts will encounter on the Moon, allowing them

3:08 Speaker 1: to practice moving and working in these challenging conditions. But

3:12 Speaker 1: Luna isn't just a giant sandbox. The facility also includes

3:15 Speaker 1: a specialized illumination system that can recreate lunar day and

3:19 Speaker 1: night cycles, each lasting fourteen Earth days. This feature will

3:23 Speaker 1: help astronauts adapt to the unique lighting conditions they'll face

3:26 Speaker 1: during lunar missions. Future plans for Luna include the addition

3:30 Speaker 1: of gravity offloading systems to simulate the Moon's reduced gravity,

3:34 Speaker 1: which is about one sixth of Earth's. This will allow

3:37 Speaker 1: astronauts to experience and train for the physical challenges of

3:41 Speaker 1: working in a low gravity environment. Luna will also serve

3:44 Speaker 1: as a test bed for robotic systems, rovers, and other

3:47 Speaker 1: tools crucial for lunar exploration. Scientists will use the facility

3:51 Speaker 1: to study the effects of moondust on equipment, helping to

3:54 Speaker 1: develop solutions for the wear and tear that lunar missions

3:58 Speaker 1: will inevitably face. By providing this realistic lunar environment, Luna

4:03 Speaker 1: is set to play a vital role in preparing astronauts

4:05 Speaker 1: and equipment for the challenges of future Moon missions, including

4:09 Speaker 1: NASA's Artemis program and beyond. Meanwhile, NASA's Artemis two crew

4:14 Speaker 1: has been getting their hands dirty in Iceland, quite literally.

4:16 Speaker 1: The team, consisting of NASA astronauts Reed Wiseman, Victor Glover,

4:20 Speaker 1: Christina Coke, and Canadian Space Agency astronaut Jeremy Hansen, recently

4:25 Speaker 1: traveled to the Nordic island for some intense geology field training.

4:28 Speaker 1: Now you might be wondering why Iceland. Well, it turns

4:31 Speaker 1: out that Iceland's unique landscape bears a striking resemblance to

4:34 Speaker 1: the lunar surface, with its vast expanses of black and

4:38 Speaker 1: gray sediment, boulder strewn grounds, devoid of vegetation, and looming

4:42 Speaker 1: shadowy mountains. It's about as close to a moonlike environment

4:45 Speaker 1: as you can get on Earth. This isn't a new

4:48 Speaker 1: concept for NASA. In fact, Iceland has been serving as

4:51 Speaker 1: a lunar stand in since the Apollo era. The similarities

4:54 Speaker 1: in geology are remarkable. Both Iceland and the Moon feature

4:57 Speaker 1: basalts and Breccia's types of rocks formed through through volcanic

5:00 Speaker 1: activity and impacts. During their training, the astronauts practice using

5:05 Speaker 1: tools similar to those used in the Apollo missions. They

5:08 Speaker 1: learn to navigate the terrain, honed their expeditionary skills, and

5:12 Speaker 1: even gave feedback to their instructors. It's all about preparing

5:15 Speaker 1: them for the challenges they'll face during lunar exploration. While

5:19 Speaker 1: the Artemis iiO mission won't actually land on the Moon,

5:22 Speaker 1: the geology fundamentals developed during this field training are crucial.

5:26 Speaker 1: The crew will be tasked with studying lunar surface features

5:29 Speaker 1: from orbit, taking photos, and describing what they see in

5:32 Speaker 1: scientific terms. This human touch and observation could provide invaluable

5:37 Speaker 1: data for researchers back on Earth as we look towards

5:40 Speaker 1: a future of sustained lunar presence. This kind of hands

5:43 Speaker 1: on training in Earth's lunar analogs will be essential in

5:46 Speaker 1: ensuring our astronauts are fully prepared for the challenges that

5:50 Speaker 1: await them on the Moon and beyond. Some launch news

5:54 Speaker 1: from China this week. China has achieved another milestone in

5:57 Speaker 1: its space program with a successful sea launch of them

6:00 Speaker 1: smart Dragon three rocket on September twenty third. The rocket

6:04 Speaker 1: lifted off from a floating platform off the eastern coast

6:06 Speaker 1: of China, carrying eight remote sensing satellites into sun synchronous orbit.

6:12 Speaker 1: This launch marks the fourth flight for the smart Dragon three,

6:15 Speaker 1: a four stage rocket standing one hundred and two feet

6:18 Speaker 1: tall and capable of delivering about three thousand, three hundred

6:21 Speaker 1: pounds of payload to orbit. What's particularly interesting about this

6:24 Speaker 1: launch is its location. By utilizing a sea based platform,

6:28 Speaker 1: China demonstrates flexibility in its launch capabilities, potentially opening up

6:32 Speaker 1: new possibilities for future missions. Sea launches offer several advantages.

6:37 Speaker 1: They allow for launches closer to the equator, which can

6:40 Speaker 1: be more efficient for certain orbits. They also provide greater

6:43 Speaker 1: launch site options and can reduce risks associated with launches

6:46 Speaker 1: over populated areas. This success isn't just significant for China,

6:51 Speaker 1: It's part of a growing trend in the space industry

6:53 Speaker 1: towards more versatile and mobile launch options. As we look

6:57 Speaker 1: to the future of space exploration in satellite deployment, innovations

7:01 Speaker 1: like sea launches could play a crucial role in making

7:03 Speaker 1: space more accessible and expanding our capabilities beyond Earth. Now,

7:09 Speaker 1: let's get an update from one of our enigmatic neighbors. Venus,

7:12 Speaker 1: often described as Earth's hellish twin, has long been considered

7:15 Speaker 1: inhospitable to life. However, recent research is challenging this assumption,

7:20 Speaker 1: offering a glimmer of hope for potential life in the

7:22 Speaker 1: most unexpected places. A new study has found that some

7:26 Speaker 1: of life's fundamental building blocks might actually survive in Venus's

7:30 Speaker 1: harsh environment. Scientists tested lipids, the essential components of cell membranes,

7:35 Speaker 1: under Venus like conditions. Surprisingly, they discovered that certain lipids

7:39 Speaker 1: can withstand exposure to concentrated sulfuric acid and even form

7:43 Speaker 1: stable structures. This finding is significant because Venus's atmosphere contains

7:47 Speaker 1: regions with temperatures and pressures that could potentially support life.

7:51 Speaker 1: While the planet's surface is indeed sterilizing, its cloud deck

7:55 Speaker 1: might hold more promise. The research suggests that stable membranes

7:59 Speaker 1: can form and persist in the presence of sulfuric acid,

8:03 Speaker 1: challenging our assumptions about the solvents necessary for life. Water

8:07 Speaker 1: has long been considered crucial, but this study shows that

8:10 Speaker 1: some aspects of life's chemistry might tolerate and even use

8:13 Speaker 1: sulfuric acid as a solvent. These findings have implications beyond Venus.

8:18 Speaker 1: Concentrated sulfuric acid could be a common planetary solvent on exoplanets,

8:23 Speaker 1: either on Venus like worlds or on rocky planets affected

8:27 Speaker 1: by their host stars activity. This broadens our understanding of

8:30 Speaker 1: potential habitable environments in the universe. While this doesn't prove

8:34 Speaker 1: the existence of life on Venus, it opens up new

8:37 Speaker 1: avenues for exploration and expands our perspective on where life

8:40 Speaker 1: might exist. As we continue to study our Solar System

8:43 Speaker 1: and beyond, we're reminded that the universe may be more

8:46 Speaker 1: hospitable to life than we once thought. Finally, today, something

8:51 Speaker 1: that may have been written off a sci fi fantasy

8:53 Speaker 1: only a few short years ago. In a groundbreaking development,

8:56 Speaker 1: scientists are testing a revolutionary space propulsion system that could

9:00 Speaker 1: reshape our approach to deep space exploration. This innovative technology,

9:04 Speaker 1: known as super mag Drive, promises to use any type

9:07 Speaker 1: of metal as fuel, potentially allowing spacecraft to travel further

9:12 Speaker 1: into the cosmos than ever before. Led by doctor Minkwon

9:15 Speaker 1: Kim from the University of Southampton, the research team is

9:18 Speaker 1: collaborating with British space firm mag Drive to test this

9:21 Speaker 1: new thruster. The system's versatility is its key advantage. It

9:25 Speaker 1: can be powered by common metals like iron, aluminum, or copper.

9:28 Speaker 1: This means that future spacecraft equipped with This technology could

9:32 Speaker 1: potentially refuel by harvesting minerals from asteroids or distant moons.

9:36 Speaker 1: The implications of this technology are truly exciting. Imagine a

9:40 Speaker 1: spacecraft landing on a metal rich comet, replenishing its fuel supply,

9:44 Speaker 1: and then continuing its journey through the Solar System and beyond.

9:48 Speaker 1: This could open up vast new frontiers in space exploration,

9:52 Speaker 1: allowing us to reach regions of the universe previously thought inaccessible.

9:57 Speaker 1: Doctor Kim, who has experienced designing plasma thruster for SpaceX,

10:01 Speaker 1: envisions this technology being used in future deep space missions.

10:05 Speaker 1: It could revolutionize our ability to explore new planets, seek

10:08 Speaker 1: out potential life, and push the boundaries of human knowledge.

10:12 Speaker 1: While still in the testing phase, the super magdrive represents

10:15 Speaker 1: a significant step forward in space propulsion technology. If successful,

10:20 Speaker 1: it could usher in a new era of space exploration,

10:23 Speaker 1: enabling longer missions and more extensive studies of our cosmic neighborhood.

10:28 Speaker 1: And that brings us to the end of today's cosmic

10:30 Speaker 1: journey through the latest in space and astronomy news. I'm Anna,
