Lunar Ambitions: China's Race to the Moon, Cosmic Discoveries Unveiled

Anna: Welcome to Astronomy Daily, your go

to podcast for the latest news from across

the cosmos. I'm Anna.

Avery: And I'm Avery. We're thrilled to have you

join us today as we dive into some truly

fascinating updates that are reshaping our

understanding of space.

Anna: Absolutely, Avery. We'll be looking

at the evolving lunar race with

some significant developments from China's

space programme that could see them reaching

the moon soon. Sooner than anticipated.

Avery: That's right. And we'll explore what those

geopolitical implications can mean for the

future of space exploration. Plus, we'll

journey deep into the galaxy to witness a

stunning cosmic discovery. Astronomers have

captured an image resembling the eye of

Sauron, revealing secrets about powerful

blazars.

Anna: And for all you planet hunters, we'll delve

into new research suggesting that many

exoplanets might be far larger than

we ever believed, completely changing our

perspective on alien worlds.

Avery: Then, as always, we'll wrap things up with

our launch roundup, including the much

anticipated 10th flight of SpaceX's

Starship and a unique biological mission

sending mice and fruit flies into orbit.

Anna: Alright, Avery, let's jump right into

what's quickly becoming the most talked about

development in space exploration.

The new space race.

China's secretive space programme has been

making some incredibly significant strides

and it seems their firmly on track to

achieve their lunar ambitions.

Avery: They certainly are, Anna. Uh, in recent

weeks, the Chinaman Space Agency, or

CMSA, has reported some major

milestones. For instance, on August 6,

they successfully tested a high fidelity

mockup of their 26 tonne Lanyue

Lunar lander. This test was quite

impressive, conducted outside Beijing using

giant tethers to simulate lunar gravity.

As the vehicle fired its main engines and

fine control thrusters to land and take take

off from a cratered surface.

Anna: That's a huge step. The

CMSA even released a statement calling

it a key step in their manned lunar

exploration programme and marking the first

time China has carried out an

extraterrestrial landing and takeoff test

for a manned spacecraft. They also

reconfirmed their plan to land astronauts on

the moon before 2030.

Avery: And it wasn't just the lander. Just last

Friday, the CMSA and their state operated

rocket developer, the China Academy of

Launch Vehicle Technology, successfully

conducted a 30 second test firing of the Long

March 10 rocket's centre core. This

rocket uses seven YF100K engines

that burn kerosene and liquid oxygen.

And the primary variant will combine three of

these cores to lift about 70 metric

tonnes to low Earth orbit.

Anna: So what we're seeing here is demonstrable

progress across all three major elements of

their lunar the large rocket to launch

a crew spacecraft, the human rated

spacecraft itself, and the lander to

take astronauts to the surface and back.

This really suggests that China is well

on course to put their taikonauts on the moon

before the end of this decade.

Avery: It does now. For the United States and its

allies, there's always been a bit of ah, a

been there, done that attitude given NASA's

Apollo programme landed humans on the moon

nearly six decades ago. NASA's Artemis

programme is of course aiming for something

different, focusing on sustainability with

in space propellant storage and refuelling

technology for reusable lower cost missions.

Anna: That's the ideal, right? Building a robust

government, commercial enterprise and a lunar

economy. However, Recent setbacks with

SpaceX's Starship vehicle, which is one

of NASA's two lunar landers under contract,

the other being Blue Origin's Mark 2

lander, indicate that these newer

technologies are still several years away

from being fully operational. This

means it's increasingly probable that China

will indeed be beat NASA back to the

moon this decade, winning at least the

initial heat of this new space race.

Avery: And that brings us to the profound

geopolitical implications of this potential

shift. Ars Technica UH recently spoke

with Dean Chiang, a highly respected

analyst focusing on China space policy

and the geopolitical aspects of this new

space competition. He shed some light

on just how significant China's progress

is.

Anna: Cheng emphasised that the Lanyu

lander test is part of China's crawl

walk run approach to major space

projects. He noted that while they can

benefit from open information like NASA's,

they still have to build and operate the

spacecraft themselves. So these tests,

successful or not, are a crucial part of

their process.

Avery: He also highlighted the successful static

test of the Long March 10 or LM10,

their lunar satellite launch vehicle. Chang

sees the LM10 even more than the Lanyue

as significant because it's a new launch

vehicle, especially given past issues with

the LM5 and the cancellation of the LM9,

which was their potential Saturn 5

equivalent. Both of these successes indicate

that the Chinese lunar programme is

definitely pushing ahead.

Anna: When asked about the likelihood of China

landing humans on the moon before NASA's

Artemis programme returns, Cheng's response

was quite direct. He stated the at the rate

things are going, sadly it seems quite likely

that the Chinese will land on the moon before

NASA can return to the moon.

Avery: That's a powerful statement and the

geopolitical impact, according to Chang,

would be enormous. He explained that it

would signify the End of American

exceptionalism. For decades, since

1969, the US has been the

only nation to land humans on another

celestial body. The saying, we've put

a man on the moon, we can do anything, would

lose its resonance.

Anna: It would also suggest that China can achieve

big things while the US struggles to

replicate projects it undertook 50 or more

years ago. This, Cheng argued, would

certainly affect other nations perceptions of

who is winning or losing the broader

technological and ideological competition

between the US and China.

Avery: He even connected it back to the idea of a

Beijing Consensus as an alternative to the

Washington Consensus. While the

Washington Consensus promotes democracy,

pluralism and capitalism, the Beijing

Consensus suggests that authoritarianism is

more likely to lead to modernization and

advancement. If Beijing can achieve these

grand space endeavours, it would reinforce

that ideological element.

Anna: And beyond just the landing, Cheng raised an

important question about the language of

cislunar space. China isn't just

aiming for a single landing. Their likely

choice of landing sites, such as the South

Pole, suggests an intent to establish

longer term facilities and a, uh, permanent

presence. If they regularly dispatch lunar

missions, they could rightfully argue that

Chinese should be a primary language, if not

the language of lunar and cislunar space

traffic management.

Avery: Not only that, but China would also have

enormous influence over technical and data

standards for CIS lunar activities. The

PRC has already indicated it will deploy a

lunar positioning, navigation and

timing network and likely a uh, communication

system. This long term

systematic approach is what Chang sees as

China's major advantage, contrasting it

with what he describes as the US's lack of

programmatic stability to despite its

economic and industrial advantages, it's

really a complex and evolving landscape.

Speaking of powerful forces at play, let's

shift gears from geopolitical competition to

a uh, truly stunning astronomical

discovery. Astronomers have recently captured

an incredibly detailed image that's being

dubbed the Eye of Sauron. And it's

beaming directly at Earth.

Anna: That's right, Avery. This isn't a new fantasy

film, but a real cosmic phenomenon. This

eye is actually the core of a powerful

blazar named PKS1424

240. Located

billions of light years away. For years

this particular blazar has puzzled

scientists. It's known as the brightest

source of neutrinos of its kind and also

shines intensely in very high energy gamma

rays.

Avery: But here's the kicker. Its cosmic jet seemed

to drift unusually slowly, which defied

the assumption that only rapidly moving jets

could produce such powerful emissions. It was

a real head scratcher.

Anna: Well, after 15 years of meticulous

observations using the Very Long Baseline

Array, or VLBA astronomers have

finally gotten an unprecedented look into

this jet structure. What they found was

absolutely stunning. Near perfect

ring shaped or toroidal magnetic

fields. These magnetic fields act like

a colossal coiled spring, accelerating

particles to extraordinary energies.

This mechanism finally explains both the high

energy neutrinos and the gamma rays pouring

from this blazar. It's a massive

breakthrough in multi messenger astronomy,

solidifying the link between these

relativistic jets, high energy

neutrinos, and the role of magnetic

fields in shaping cosmic accelerators.

It's truly like looking directly into the

heart of a cosmic monster.

And speaking of rethinking what we see, I

want to talk about some new research that's

completely changing our perspective on

exoplanets. It turns out hundreds

of distant planets we thought we knew might

be far larger than we ever believed.

Avery: That's quite a revelation. How did scientists

miss something so significant?

Anna: It comes down to how these exoplanets are

detected. NASA's Transiting Exoplanet

Survey Satellite TESS, launched in 2018,

finds planets by observing tiny dips in

starlight as a planet passes in front of its

star. The size of that dip tells us the

planet's size. But here's the

TESS has relatively low resolution and

sometimes light from other nearby stars can

mix with the target star's light. This makes

the planet's shadow appear smaller than it

truly is, leading to an underestimation of

its size.

Avery: So it's like an optical illusion in space.

Anna: Precisely. A new study led by Tay

Han at the University of California, Irvine

uncovered how serious this problem is. They

found that many planet sizes have been

underestimated by about 6.1%.

While that might not sound like much because

density is calculated using both size and

mass, a small error in radius leads to

a much bigger mistake in density, around

20% too high. This has huge

implications for how we understand planet

formation, density, and even the potential

for life beyond Earth.

Avery: So what does this mean for our search for

Earth like worlds?

Anna: Well, it means we might have found fewer

Earth like planets so far than we thought we

had. Many planets once classified as

rocky Earth sized worlds could now be

reclassified as larger, less Earth like

planets, perhaps water rich ocean worlds,

or even larger gas layers like Uranus or

Neptune. This doesn't rule out life, but it

shifts our focus and makes us rethink where

to look and how we interpret the data.

Especially when prioritising targets for

follow up observations with telescopes like

the James Webb Space Telescope.

Avery: That truly sheds new light on our

understanding of exoplanets. Anna, huh?

And speaking of things that are constantly

changing, we have a packed week ahead with

several crucial launches across the globe.

Anna: Absolutely, Avery. From a highly

anticipated starship flight to unique

biological missions, let's dive into our

launch roundup.

Avery: First up, all eyes are in Texas for the much

anticipated 10th flight of SpaceX's

Starship. Ship 37, mounted on

booster 16 is scheduled to launch this

Sunday, August 24th from Starbase.

This mission is pivotal as the starship

programme is looking to recover from recent

setbacks, including the explosion of ship 36

during a test.

Anna: That's right, SpaceX has been working hard,

even designing a special mount to static fire

ship 37 on the orbital launch padding

after their Massey's test facility was

knocked out of service. As we reported last

week on this flight, ship 37 will

deploy eight dummy Starlink satellites and

collect crucial re entry data before a

planned splashdown in the Indian Ocean.

It's also notable as the fourth Starship

flight of 2025, and hopefully the first

entirely successful Block 2 flight if

it splashes down intact.

Avery: Over in Russia, Roscosmos has a

fascinating biological mission scheduled. The

Bon M M number two mission is set to launch

on Wednesday, August 20 aboard a

Soyuz 2.1A rocket from Baikonur

Cosmodrome. This mission is particularly

interesting because its 6300 kilogramme

bion m m spacecraft is derived from the

Vostok capsule which launched Yuri Gagarin

into space back in 1961.

Anna: It's a piece of history. Flying again. The

Bion m m number two will carry 75 mice and a

thousand fruit flies, along with plants and

microorganisms to study how they're affected

by radiation at a molecular level. The

mission is slated to last 30 days before the

spacecraft returns to Earth with its living

cargo.

Avery: And that's not all. For the week. China

CAS Space is flying its second

Connecticut 1 mission of the year, carrying

seven satellites to to sun synchronous orbit,

including two Mexican Femto satellites.

Russia also has an Angara 1.2

rocket launching from Plesetsk with an

unknown payload, likely a military

satellite.

Anna: Not to be outdone, SpaceX has several

other Falcon 9 launches on the manifest.

We're looking forward to the United states

Space Force 36 National Security

Mission featuring the X37B

Orbital Test Vehicle and and a cargo

Dragon flight to the International Space

station, delivering over 2,200

kilogrammes of supplies and experiments,

including studies on engineered liver tissue

and bone marrow stem cells. It's

truly a, uh, busy week in space.

Avery: What an incredible day for space and

astronomy news. We've covered everything

from China's significant strides in the lunar

race, potentially beating the US Back to

the Moon, and and the profound geopolitical

implications of that.

Anna: We also delved into the cosmic wonders of the

Eye of Sauron Blazar, revealing how

magnetic fields accelerate particles to

extreme energies, and learned that

exoplanets might be much larger than we

initially thought, shifting our perspective

on where life might exist.

Avery: And of course, we wrap things up with a, uh,

look at the exciting launches on the horizon,

including starship's anticipated Flight 10

and Russia's unique biological mission

carrying mice and fruit flies into orbit.
