S03E157: Mini Moon Arrival, Spacecraft Servicing, and Europa's Mysteries

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

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

0:05 Speaker 1: an exciting lineup for you. Today. We'll be diving into

0:08 Speaker 1: recent developments in asteroid detection, exploring NASA's ambitious europe emission,

0:13 Speaker 1: discussing Earth's upcoming mini moon, recapping the first ever private spacewalk,

0:18 Speaker 1: and examining the potential for servicing spacecraft at the L

0:21 Speaker 1: two lagrange point. Get ready for a cosmic journey as

0:25 Speaker 1: we explore these fascinating topics from across the Solar System

0:28 Speaker 1: and beyond. To get us started, let's dive into some

0:31 Speaker 1: exciting developments in asteroid detection. On September fourth, astronomers spotted

0:35 Speaker 1: a small asteroid just one meter in diameter heading towards Earth.

0:39 Speaker 1: This space rock, known as RW one, harmlessly burned up

0:43 Speaker 1: in the atmosphere near the Philippines later that same day,

0:46 Speaker 1: creating a spectacular fireball that lit up social media. What's

0:51 Speaker 1: remarkable about this event is that our W one was

0:54 Speaker 1: only the ninth asteroid ever detected before impact. It's a

0:58 Speaker 1: testament to our improving ability to spot even small objects

1:00 Speaker 1: hurtling towards Earth. But what about larger, more dangerous asteroids.

1:05 Speaker 1: Scientists are working tirelessly to enhance our early warning systems. Currently,

1:10 Speaker 1: we know of about thirty six thousand near Earth objects,

1:13 Speaker 1: ranging from a few meters to several kilometers in size. However,

1:17 Speaker 1: statistical models suggest there could be nearly a billion such

1:20 Speaker 1: objects out there. To address this challenge, NASA has allocated

1:23 Speaker 1: ninety million dollars to hunt for near Earth objects. New

1:27 Speaker 1: projects like the Sutter Ultra and NASA's Neo Surveyor Infrared

1:30 Speaker 1: Telescope Mission are being developed to detect hazardous objects from space.

1:34 Speaker 1: Artificial intelligence is also playing a crucial role. Advanced algorithms

1:38 Speaker 1: are being employed to automate the process of sorting through

1:40 Speaker 1: the massive amount of image data generated by detection programs

1:44 Speaker 1: every day. While we've made significant progress, there's still work

1:47 Speaker 1: to be done. As of twenty twenty three, we've identified

1:50 Speaker 1: about thirty eight percent of all existing near Earth objects

1:53 Speaker 1: one hundred and forty meters or larger. With new telescopes

1:56 Speaker 1: coming online like the US via Rubin eight point five

2:00 Speaker 1: meter telescope, we hope to increase this to sixty percent

2:03 Speaker 1: by twenty twenty five, and potentially up to seventy six

2:07 Speaker 1: percent by twenty twenty seven with NASA's Neo Surveyor. These

2:11 Speaker 1: advancements are crucial for our planetary defense. While we may

2:14 Speaker 1: never detect every object that could cause localized damage, our

2:18 Speaker 1: improving capabilities give us a better chance to prepare and

2:21 Speaker 1: react to potential threats from space. While on the topic

2:25 Speaker 1: of NASA projects, NASA's upcoming Europa Clipper mission is set

2:29 Speaker 1: to embark on an extraordinary journey to one of Jupiter's

2:33 Speaker 1: most intriguing moons. Europa has long fascinated scientists due to

2:37 Speaker 1: the strong evidence of a vast salty ocean hidden beneath

2:41 Speaker 1: its icy crust. This mission aims to investigate whether this

2:44 Speaker 1: distant world could potentially harbor life. The Europa Clipper spacecraft

2:48 Speaker 1: is a marvel of engineering, standing as the largest planetary

2:51 Speaker 1: mission spacecraft ever built by NASA. Its massive solar arrays,

2:56 Speaker 1: spanning one hundred feet from end to end, are designed

2:59 Speaker 1: to capture enough sunlight light in the dim Jovian System

3:02 Speaker 1: to power its suite of advanced instruments. The mission's primary

3:05 Speaker 1: objective is to determine if Europa possesses the necessary ingredients

3:09 Speaker 1: for life, water, energy, and the right chemical composition. To

3:13 Speaker 1: accomplish this, Europa Clipper will perform forty nine close flybys

3:18 Speaker 1: of the Moon, each time diving through Jupiter's intense radiation

3:22 Speaker 1: belts to collect crucial data. The spacecraft carries nine cutting

3:26 Speaker 1: edge scientific instruments, including cameras, spectrometers, and radar systems. These

3:32 Speaker 1: tools will work in concert to map Europa's surface, probe

3:35 Speaker 1: its internal structure, and analyze its potential for habitability. One

3:39 Speaker 1: of the most exciting aspects of this mission is the

3:42 Speaker 1: possibility of detecting plumes of water vapor erupting from Europa's surface.

3:46 Speaker 1: If found, these plumes could provide a direct sample of

3:49 Speaker 1: the subsurface ocean without the need to drill through miles

3:52 Speaker 1: of ice. Europa Clipper is scheduled to launch in October

3:56 Speaker 1: twenty twenty four, embarking on a complex trajectory that will

4:00 Speaker 1: use Mars and Earth for gravity assists before reaching Jupiter

4:03 Speaker 1: in twenty thirty. This ambitious mission promises to revolutionize our

4:07 Speaker 1: understanding of icy worlds and expand our search for life

4:10 Speaker 1: beyond Earth. Here's something we don't get to say too often.

4:14 Speaker 1: Earth is about to get a new companion, albeit a

4:16 Speaker 1: temporary one. This month, a tiny asteroid known as twenty

4:20 Speaker 1: twenty four PT five will become our planet's second moon

4:23 Speaker 1: for a brief period of about two months. Unlike our

4:25 Speaker 1: familiar lunar companion that's been with us for billions of years,

4:29 Speaker 1: this mini moon is just passing through. It belongs to

4:32 Speaker 1: the Arjuna asteroid Belt, a collection of space rocks that

4:35 Speaker 1: follow orbits similar to Earth's. These mini moon events occur

4:39 Speaker 1: when objects approach Earth at just the right distance and speed,

4:42 Speaker 1: allowing our planet's gravity to temporarily capture them. In the

4:46 Speaker 1: case of twenty twenty four PT five, it will come

4:48 Speaker 1: within about two point eight million miles of Earth, traveling

4:52 Speaker 1: at a relatively slow two thy two hundred miles per hour.

4:55 Speaker 1: While this celestial visitor won't be visible to the naked

4:57 Speaker 1: eye or even most amateur telescopes, it represents an interesting

5:01 Speaker 1: astronomical phenomenon. These temporary captures happen more often than you

5:05 Speaker 1: might think, with several occurring each decade. Unfortunately, twenty twenty

5:09 Speaker 1: four PT five won't complete a full orbit around Earth

5:12 Speaker 1: during its brief stay. Think of it more as a

5:14 Speaker 1: cosmic window shopper, briefly drawn in by Earth's gravitational pull

5:18 Speaker 1: before continuing on its journey around the Sun. This event

5:21 Speaker 1: serves as a reminder of the dynamic nature of our

5:23 Speaker 1: Solar system and the complex dance of celestial bodies constantly

5:27 Speaker 1: occurring around us. Next up, in a historic moment for

5:30 Speaker 1: commercial space exploration, the SpaceX Polaris Dawn mission recently achieved

5:35 Speaker 1: the first ever spacewalk by private astronauts. Mission commander Jared

5:39 Speaker 1: isaac Mann and SpaceX engineer Sarah Gillis ventured outside their

5:43 Speaker 1: Dragon spacecraft, marking a significant milestone in the private space industry.

5:48 Speaker 1: Isaac Man described opening the hatch into the void as

5:50 Speaker 1: an emotional experience that left him in awe. He spoke

5:53 Speaker 1: of the sensory overload from physical exertion to pressure and

5:57 Speaker 1: temperature changes. The view of Earth unobstruct did except for

6:00 Speaker 1: his visor, was overwhelming. Yet isaac Mann emphasized that despite

6:04 Speaker 1: the planet's beauty, the experience was far from peaceful, likening

6:08 Speaker 1: it to the challenges faced by early maritime explorers. While

6:11 Speaker 1: Gillis didn't have the same stunning Earth views, she had

6:14 Speaker 1: a unique experience of her own. As a classically trained violinist,

6:18 Speaker 1: She performed raised theme from Star wars in space using

6:21 Speaker 1: a specially prepared instrument that could withstand the vacuum. This

6:24 Speaker 1: groundbreaking space walk not only pushes the boundaries of commercial

6:28 Speaker 1: space activities, but also contributes to the development of SpaceX's

6:32 Speaker 1: next generation spacesuit. As private companies set their sites on

6:35 Speaker 1: more ambitious goals like Mars colonization, such milestones pave the

6:39 Speaker 1: way for future advancements in space exploration technology and capabilities. Now,

6:44 Speaker 1: let's turn our attention to an exciting new development that

6:47 Speaker 1: could revolutionize how we maintain our space observatories. NASA researchers

6:52 Speaker 1: have recently published a study exploring the potential for servicing

6:55 Speaker 1: and refueling spacecraft at the Sun Earth Lagrange point two,

6:59 Speaker 1: or L two. This is a crucial area of space

7:02 Speaker 1: where some of our most important observatories operate, including the

7:05 Speaker 1: James Webb Space Telescope and the Gay Emission. These telescopes

7:09 Speaker 1: provide us with incredible scientific insights, but they're limited by

7:12 Speaker 1: factors like fuel supply and componentware. The NASA study investigates

7:16 Speaker 1: the feasibility of sending robotic missions to L two to

7:20 Speaker 1: refuel and repair these valuable assets. This could significantly extend

7:23 Speaker 1: their operational lifespans, giving us more bang for our astronomical book.

7:27 Speaker 1: The researchers focused on computing optimal trajectories for these potential

7:31 Speaker 1: servicing missions. They considered various factors, including launch options from

7:35 Speaker 1: Earth or geostationary transfer orbits, the dynamics of the Lagrange point,

7:40 Speaker 1: and the challenges of rendezvousing with a moving target in space.

7:44 Speaker 1: While current telescopes weren't designed for on orbit servicing, future

7:47 Speaker 1: observatories could be built with this capability in mind. The

7:50 Speaker 1: study's findings could inform the design of both future space

7:53 Speaker 1: telescopes and the servicing craft that might one day maintain them.

7:57 Speaker 1: If successful, this approach could transform how we think about

8:00 Speaker 1: the lifespan of our space based observatories, potentially allowing us

8:05 Speaker 1: to keep these incredible scientific instruments operational for much longer

8:09 Speaker 1: than currently possible. And that brings us to the end

8:13 Speaker 1: of today's cosmic journey. Through the latest developments in space

8:16 Speaker 1: and astronomy. From advancements in asteroid detection to groundbreaking missions

8:21 Speaker 1: like Europa Clipper, we've covered a lot of exciting territory.
