New Horizons Milestone, Gravitational Wave Breakthrough, and Health in Space: S04E44

0:00 Speaker 1: Welcome to Astronomy Daily. I'm excited to bring you another

0:02 Speaker 1: packed episode of space and astronomy news. Today, we have

0:06 Speaker 1: an incredible lineup of stories that showcase just how dynamic

0:09 Speaker 1: and fascinating our exploration of space continues to be. We'll

0:13 Speaker 1: start with NASA's new Horizon spacecraft as it approaches a

0:16 Speaker 1: historic milestone that could revolutionize our understanding of the Solar

0:21 Speaker 1: System's outer boundaries. Then we'll dive into a breakthrough in

0:24 Speaker 1: gravitational wave detection that could help us peer further back

0:28 Speaker 1: in time than ever before. We've also got fascinating updates

0:32 Speaker 1: from the International Space Station, where scientists are conducting crucial

0:36 Speaker 1: experiments on antibiotic resistant bacteria. Plus, we'll cover some remarkable

0:41 Speaker 1: developments in lunar exploration and a new method that could

0:45 Speaker 1: help us in the search for alien life. Stay with

0:48 Speaker 1: me as we explore these stories and more right here

0:50 Speaker 1: on Astronomy Daily. NASA's New Horizon spacecraft, already famous for

0:56 Speaker 1: giving us our first close up views of Pluto in

0:58 Speaker 1: twenty fifteen, is gearing up for another groundbreaking achievement. The

1:03 Speaker 1: probe is preparing to cross what scientists call the termination shock,

1:07 Speaker 1: a fundamental boundary where our Sun's influence begins to wane

1:10 Speaker 1: as it meets the interstellar medium. This milestone crossing could

1:14 Speaker 1: happen as early as twenty twenty seven, and the spacecraft's

1:16 Speaker 1: team is working diligently to ensure they don't miss this

1:20 Speaker 1: rare opportunity. The actual crossing might only last about ten minutes,

1:24 Speaker 1: though multiple crossings could occur as the boundary moves back

1:27 Speaker 1: and forth over several days. New Horizons is uniquely equipped

1:32 Speaker 1: for this mission, carrying specialized instruments that can measure particles

1:35 Speaker 1: and energy in ways that weren't possible during previous boundary

1:38 Speaker 1: crossings by other spacecraft. Its Solar Wind Around Pluto instrument

1:43 Speaker 1: and Pluto Energetic Particle Spectrometer will conduct the first ever

1:47 Speaker 1: measurements of crucial pickup ions in the outer heliosphere. The

1:51 Speaker 1: spacecraft remains in excellent condition, with all seven of its

1:54 Speaker 1: instruments working as well as they did at launch. While

1:57 Speaker 1: fuel reserves are running low, nuclear power system could potentially

2:01 Speaker 1: keep it operational until twenty fifty. This impressive longevity means

2:06 Speaker 1: New Horizons could continue providing valuable data about this unexplored

2:10 Speaker 1: region of space for years to come. The mission's findings

2:14 Speaker 1: are particularly significant because they could help solve several mysteries

2:17 Speaker 1: about our Solar system's outer boundaries. Scientists are especially interested

2:22 Speaker 1: in understanding how the solar wind interacts with the interstellar medium,

2:27 Speaker 1: and how this interaction shapes the bubble of space we

2:30 Speaker 1: call home. This upcoming crossing represents another chapter in New

2:34 Speaker 1: Horizon's remarkable journey, which has already revolutionized our understanding of

2:39 Speaker 1: Pluto and the Kuiper Belt. The data it collects could

2:42 Speaker 1: be crucial for planning future missions into interstellar space and

2:46 Speaker 1: understanding the fundamental nature of our cosmic neighborhood. Next up, today,

2:52 Speaker 1: scientists have achieved a remarkable breakthrough in gravitational wave detection

2:55 Speaker 1: technology that could revolutionize our ability to observe some of

2:59 Speaker 1: the most dramatic events in the cosmos. This new advancement

3:02 Speaker 1: in adaptive optics promises to dramatically enhance the capabilities of

3:06 Speaker 1: facilities like LEGO, the Laser Interferometer Gravitational Wave Observatory, and

3:11 Speaker 1: set the stage for even more powerful future observatories. The

3:15 Speaker 1: heart of this innovation lies in its ability to correct

3:18 Speaker 1: distortions in ligo's massive forty kilogram mirrors, as laser power

3:23 Speaker 1: increases in these detectors, it creates heat that warps these

3:27 Speaker 1: crucial components. The new system can precisely adjust for these distortions,

3:32 Speaker 1: allowing the observatories to use laser power levels exceeding one megawat,

3:36 Speaker 1: far beyond current capabilities. This technological leap forward is particularly

3:41 Speaker 1: exciting for the planned Cosmic Explorer, which will feature interferometer

3:45 Speaker 1: arms stretching forty kilometers ten times longer than lego's current setup.

3:49 Speaker 1: When operating at full sensitivity, these enhanced detectors will be

3:53 Speaker 1: able to peer back to when the universe was just

3:55 Speaker 1: a fraction of its current age, before the first stars

3:58 Speaker 1: even began to shine. The implications for our understanding of

4:02 Speaker 1: the cosmos are profound. With this increased sensitivity, scientists will

4:07 Speaker 1: be better equipped to study the nature of black holes,

4:10 Speaker 1: measure the expansion rate of the universe with unprecedented precision,

4:14 Speaker 1: and potentially resolve current contradictions in our cosmological models. We

4:20 Speaker 1: might even discover entirely new types of astronomical phenomena that

4:24 Speaker 1: we haven't yet imagined. The technology could help answer some

4:28 Speaker 1: of the most fundamental questions in physics and cosmology. From

4:31 Speaker 1: testing the predictions of general relativity to understanding the detailed

4:35 Speaker 1: dynamics around black hole event horizons. This marks another significant

4:40 Speaker 1: step forward in our ability to observe the universe not

4:43 Speaker 1: just through light, but through the very ripples in the

4:45 Speaker 1: fabric of space time itself. Our next story is all

4:50 Speaker 1: about making sure our intrepid space explorers stay healthy. NASA

4:54 Speaker 1: is taking bold steps to protect astronaut health and advance

4:57 Speaker 1: medical science with a groundbreaking new experiment aboard the International

5:01 Speaker 1: Space Station. The study, called GEARS Genomic Enumeration of Antibiotic

5:06 Speaker 1: Resistance in Space, aims to speed up the detection of

5:09 Speaker 1: antibiotic resistant bacteria, a growing concern both in space and

5:13 Speaker 1: on Earth. With future missions to the Moon and Mars

5:16 Speaker 1: on the horizon, astronauts will need to rely on a

5:19 Speaker 1: limited supply of antibiotics to combat potential infections. Ensuring these

5:24 Speaker 1: medications remain effective is crucial for crue safety, especially when

5:28 Speaker 1: they're millions of miles from home. The GEARS experiment focuses

5:32 Speaker 1: particularly on Enterococcus ficalis, a common bacteria that has become

5:37 Speaker 1: the second leading cause of hospital acquired infections. Over the

5:42 Speaker 1: next year, astronauts will collect samples from various surfaces throughout

5:46 Speaker 1: the station and analyze them using advanced genetic sequencing techniques,

5:50 Speaker 1: marking the first time this type of comprehensive DNA analysis

5:54 Speaker 1: has been performed in space. The goal is to develop

5:57 Speaker 1: a rapid testing system that can identify dangerous bacteria in

6:01 Speaker 1: hours rather than days. The implications extend far beyond space exploration.

6:06 Speaker 1: Back on Earth, antibiotic resistant infections claim over thirty five

6:10 Speaker 1: thousand lives annually. The streamline detection methods being developed through

6:14 Speaker 1: GEARS could revolutionize how hospitals identify and treat these dangerous infections,

6:20 Speaker 1: potentially saving countless lives. Initial results from the experiment have

6:24 Speaker 1: been encouraging. The first round of testing revealed surprisingly few

6:28 Speaker 1: resistant bacteria colonies aboard the station, suggesting current cleaning protocols

6:32 Speaker 1: are effective. However, researchers are now strategically pausing some cleaning

6:38 Speaker 1: routines to better understand how these bacteria might naturally spread

6:43 Speaker 1: in the space environment. This marriage of space research and

6:47 Speaker 1: medical advancement exemplifies how NASA's missions continue to drive innovations

6:51 Speaker 1: that benefit life on Earth. The techniques being pioneered miles

6:55 Speaker 1: above our planet today could be saving lives in hospitals

6:59 Speaker 1: around the world tomorrow from today's news headlines. In a

7:03 Speaker 1: remarkable space related incident, debris from a SpaceX Falcon nine

7:07 Speaker 1: rocket made an uncontrolled re entry over Poland earlier today.

7:11 Speaker 1: The rocket, which originally launched from Vandenberg Air Force Base

7:14 Speaker 1: in California on February first as part of a Starlink

7:17 Speaker 1: satellite mission, created quite a spectacle as it returned to Earth.

7:22 Speaker 1: Residents in western Poland were treated to an extraordinary light

7:25 Speaker 1: show as the debris blazed through the atmosphere around four

7:28 Speaker 1: forty six am local time. The luminous trails visible in

7:32 Speaker 1: the night sky marked the final moments of this piece

7:35 Speaker 1: of space hardware's journey. Two significant pieces of the rocket

7:39 Speaker 1: have been recovered so far. The first was discovered Wednesday

7:43 Speaker 1: morning in the outskirts of Poznan, where a chunk measuring

7:46 Speaker 1: approximately five feet by three feet was found on warehouse property.

7:51 Speaker 1: Hours later, a second piece of similar size was located

7:54 Speaker 1: in a nearby forest just a few kilometers away. The

7:58 Speaker 1: Polish space agency PULSA has confirmed the debris originated from

8:02 Speaker 1: the Falcon nine rockets second stage. They're currently in communication

8:06 Speaker 1: with SpaceX to gather more information about the re entry event. Importantly,

8:11 Speaker 1: despite the dramatic nature of the incident, no injuries or

8:14 Speaker 1: property damage have been reported. This event serves as a

8:17 Speaker 1: reminder that what goes up must eventually come down. Even

8:21 Speaker 1: in the space industry. While most rocket stages are designed

8:25 Speaker 1: to burn up completely during re entry, occasionally larger pieces

8:29 Speaker 1: can survive the journey through the atmosphere, as we've seen

8:32 Speaker 1: in this case. Next, Firefly Aerospace's Blue GHOSTS lunar lander

8:38 Speaker 1: continues to make impressive progress in its journey to the Moon.

8:41 Speaker 1: After completing its four day transit from Earth, the spacecraft

8:44 Speaker 1: has successfully entered lunar orbit and is now preparing for

8:47 Speaker 1: what could be a historic landing attempt in just under

8:50 Speaker 1: two weeks. The mission team recently executed a precise engine

8:54 Speaker 1: burn lasting three minutes and eighteen seconds, which successfully lowered

8:58 Speaker 1: Blue Ghost's orbit to approximately seventy five miles above the

9:01 Speaker 1: lunar surface. This crucial maneuver has positioned the spacecraft perfectly

9:06 Speaker 1: for its upcoming landing attempt, currently scheduled for March second.

9:11 Speaker 1: As the spacecraft circles the Moon, mission controllers are experiencing

9:15 Speaker 1: expected communication blackouts when Blue Ghost passes behind the lunar

9:19 Speaker 1: far side. However, during its near side passes, the team

9:24 Speaker 1: continues to receive valuable telemetry data and is using this

9:27 Speaker 1: information to fine tune the final landing sequence. Blue Ghost

9:31 Speaker 1: is carrying ten NASA research payloads as part of the

9:35 Speaker 1: Commercial Lunar Payload Services Program. These experiments are designed to

9:39 Speaker 1: study the lunar environment and will support NASA's broader Artemis

9:43 Speaker 1: program goals. If successful, this mission will mark only the

9:47 Speaker 1: second time a private company has achieved a soft landing

9:50 Speaker 1: on the Moon. The spacecraft will have approximately two weeks

9:54 Speaker 1: one full lunar day to complete its scientific mission once

9:57 Speaker 1: it touches down. During this time, its suite of instruments

10:01 Speaker 1: will be busy collecting samples, testing components, and gathering crucial

10:05 Speaker 1: data to support future lunar missions. The mission represents a

10:09 Speaker 1: significant milestone in commercial space exploration and could help pave

10:13 Speaker 1: the way for more frequent and sophisticated private missions to

10:16 Speaker 1: the Moon's surface. Now here's a subject we never seem

10:20 Speaker 1: to stray too far away from. In an exciting development

10:24 Speaker 1: for the search for extraterrestrial life, astronomers have discovered a

10:28 Speaker 1: new tool that could help narrow down which planets might

10:30 Speaker 1: harbor life. The key lies in an unexpected place, sulfur

10:34 Speaker 1: dioxide in planetary atmospheres. This discovery could be particularly valuable

10:39 Speaker 1: when studying planets around red dwarf stars, which are the

10:42 Speaker 1: most common type of star in our galaxy. Many nearby

10:45 Speaker 1: star systems, including Proxima, Centaury, and trappist I, fall into

10:50 Speaker 1: this category, making them prime targets for our search for

10:53 Speaker 1: alien life? What makes sulfur dioxide such a useful indicator?

10:58 Speaker 1: On warm, wet planets like Earth, sulfur dioxide levels remain

11:01 Speaker 1: low because rain naturally removes it from the atmosphere. However,

11:05 Speaker 1: on dry, uninhabitable planets orbiting red dwarf stars, sulfur dioxide

11:10 Speaker 1: can persist in high concentrations in the upper atmosphere due

11:13 Speaker 1: to these stars low ultraviolet radiation output. This means that

11:17 Speaker 1: if astronomers detect significant levels of sulfur dioxide in a

11:21 Speaker 1: rocky planet's atmosphere around a red dwarf it likely indicates

11:24 Speaker 1: a hot, dry world with little to no water, similar

11:28 Speaker 1: to Venus. Such planets can be removed from the priority

11:32 Speaker 1: list in our search for life. Conversely, planets with low

11:35 Speaker 1: sulfur dioxide levels might be more promising candidates for further investigation.

11:40 Speaker 1: While this method won't directly identify planets that host life,

11:44 Speaker 1: it serves as an efficient way to eliminate unlikely candidates,

11:47 Speaker 1: allowing researchers to focus their limited resources on the most

11:51 Speaker 1: promising worlds. As we continue our quest to find life

11:54 Speaker 1: beyond Earth, having such filtering tools becomes increasingly valuable, especially

11:58 Speaker 1: given the challenges into taytecting direct biosignatures with current technology.

12:04 Speaker 1: And that's it for this episode. Thank you for joining
