00:00:36 --> 00:00:38 distant exoplanets, today's episode spans
00:00:38 --> 00:00:41 the full spectrum of space exploration. So
00:00:41 --> 00:00:43 buckle up for a journey through the latest
00:00:43 --> 00:00:44 wonders and debates in astronomy and space
00:00:44 --> 00:00:45 exploration.
00:00:46 --> 00:00:48 In what might be one of the most intriguing
00:00:48 --> 00:00:50 discoveries in astrobiology this year,
00:00:51 --> 00:00:53 scientists have identified a completely new
00:00:53 --> 00:00:55 bacterium aboard China's Tiangong Space
00:00:55 --> 00:00:58 Station. This microscopic organism,
00:00:58 --> 00:01:01 which has been named Nyalia tiangongensis,
00:01:01 --> 00:01:03 has never been documented on Earth before,
00:01:03 --> 00:01:05 raising fascinating questions about microbial
00:01:05 --> 00:01:07 adaptation and evolution in space
00:01:07 --> 00:01:10 environments. The discovery came through
00:01:10 --> 00:01:13 work led by Dr. Junxia Yuan from the
00:01:13 --> 00:01:15 Shenzhou Space Biotechnology Group in
00:01:15 --> 00:01:18 Beijing. Following detailed genetic and
00:01:18 --> 00:01:21 biochemical analysis of samples collected as
00:01:21 --> 00:01:23 part of the China Space Station Habitation
00:01:23 --> 00:01:26 Area Microbiome Programme, or
00:01:26 --> 00:01:28 champ, researchers confirmed they were
00:01:28 --> 00:01:31 dealing with an entirely new species. What
00:01:31 --> 00:01:33 makes this tiny hitchhiker particularly
00:01:33 --> 00:01:35 interesting is how well suited it appears to
00:01:35 --> 00:01:38 be for life in orbit. The bacterium is rod
00:01:38 --> 00:01:41 shaped and microscopic, but its most notable
00:01:41 --> 00:01:43 feature is its ability to form spores,
00:01:43 --> 00:01:46 resilient structures that help certain
00:01:46 --> 00:01:48 microorganisms survive harsh conditions.
00:01:49 --> 00:01:51 This adaptation may be crucial for enduring
00:01:51 --> 00:01:53 the extreme radiation and microgravity
00:01:53 --> 00:01:55 environment hundreds of miles above Earth's
00:01:55 --> 00:01:58 surface. The researchers also noted that
00:01:58 --> 00:02:00 Nyalia tiangongensis breaks down
00:02:00 --> 00:02:03 gelatin in a distinctive way, which could be
00:02:03 --> 00:02:05 an important survival mechanism in the
00:02:05 --> 00:02:07 nutrient limited environment of a space
00:02:07 --> 00:02:09 station. This ability to efficiently process
00:02:10 --> 00:02:12 available resources might explain how the
00:02:12 --> 00:02:14 microbe has managed to thrive in such an
00:02:14 --> 00:02:17 isolated ecosystem. Space stations are
00:02:17 --> 00:02:19 essentially sealed habitats containing
00:02:19 --> 00:02:21 people, equipment, and countless
00:02:21 --> 00:02:24 microorganisms. Many of these microbes
00:02:24 --> 00:02:27 originate from crew members or cargo, making
00:02:27 --> 00:02:28 it challenging to determine whether this
00:02:28 --> 00:02:30 bacterium was a stowaway from Earth that
00:02:30 --> 00:02:33 developed new traits, or if it somehow
00:02:33 --> 00:02:35 evolved in response to the unique conditions
00:02:35 --> 00:02:38 of space. Experts studying
00:02:38 --> 00:02:40 microbial behaviour in orbit have previously
00:02:40 --> 00:02:42 observed how certain species can form
00:02:42 --> 00:02:45 biofilms, films, structured communities that
00:02:45 --> 00:02:47 increase resistance to environmental
00:02:47 --> 00:02:49 stressors. A NASA study on the International
00:02:50 --> 00:02:52 Space Station demonstrated that some microbes
00:02:52 --> 00:02:54 can develop heightened tolerance to the
00:02:54 --> 00:02:56 elevated radiation levels encountered in low
00:02:56 --> 00:02:59 Earth orbit. The new bacterium appears to be
00:02:59 --> 00:03:02 related to Nyalia circulens, a known
00:03:02 --> 00:03:05 Earth microbe that can cause sepsis in people
00:03:05 --> 00:03:07 with compromised immune systems. However, it
00:03:07 --> 00:03:09 remains unclear whether this species space
00:03:09 --> 00:03:12 station variant carries similar health risks
00:03:12 --> 00:03:14 or has acquired new properties that might
00:03:14 --> 00:03:16 affect its interaction with humans.
00:03:17 --> 00:03:19 This discovery underscores just how little we
00:03:19 --> 00:03:21 know about the vast array of microorganisms
00:03:21 --> 00:03:24 around us. While tens of thousands of
00:03:24 --> 00:03:26 bacterial species have been catalogued,
00:03:26 --> 00:03:28 billions more remain unidentified.
00:03:29 --> 00:03:31 The emergence of this space adapted bacterium
00:03:31 --> 00:03:33 serves as a reminder that life finds
00:03:33 --> 00:03:36 extraordinary ways to adapt to even the most
00:03:36 --> 00:03:38 extreme environments humans create.
00:03:39 --> 00:03:42 Next up, an update to a story we brought you
00:03:42 --> 00:03:44 some weeks ago. A scientific debate is
00:03:44 --> 00:03:46 heating up in the astronomy community over
00:03:46 --> 00:03:47 what would have been groundbreaking
00:03:47 --> 00:03:50 newspotential signs of life on an
00:03:50 --> 00:03:52 exoplanet. In 2023, a
00:03:52 --> 00:03:55 team from Cambridge University announced that
00:03:55 --> 00:03:58 NASA's James Webb Space Telescope had
00:03:58 --> 00:04:00 detected what appeared to be evidence of a
00:04:00 --> 00:04:02 liquid water ocean on K2
00:04:02 --> 00:04:05 18B, a temperate sub Neptune world
00:04:05 --> 00:04:08 about 124 light years from Earth.
00:04:08 --> 00:04:10 Earlier this year, the same researchers
00:04:10 --> 00:04:13 doubled down on their claims, suggesting they
00:04:13 --> 00:04:15 had found even stronger evidence for possible
00:04:15 --> 00:04:18 alien life. The excitement centred around a
00:04:18 --> 00:04:20 tentative detection of demethyl sulphide, or
00:04:20 --> 00:04:23 dms, a molecule that on Earth is produced
00:04:23 --> 00:04:26 exclusively by marine organisms. They also
00:04:26 --> 00:04:29 potentially identified DMDs, a close
00:04:29 --> 00:04:31 chemical relative that could similarly
00:04:31 --> 00:04:33 indicate biological processes. Combined
00:04:33 --> 00:04:36 with the possibility that K2 18B is what
00:04:36 --> 00:04:39 scientists call a hycean world, a planet
00:04:39 --> 00:04:41 with a hydrogen rich atmosphere above a
00:04:41 --> 00:04:44 liquid water ocean, these findings generated
00:04:44 --> 00:04:46 tremendous media attention and speculation
00:04:46 --> 00:04:49 about the first potential detection of alien
00:04:49 --> 00:04:52 life. However, independent research
00:04:52 --> 00:04:54 teams have been conducting their own analyses
00:04:54 --> 00:04:56 and the results are casting significant doubt
00:04:56 --> 00:04:59 on these claims. A new study led by
00:04:59 --> 00:05:02 Rafael Luke from the University of Chicago
00:05:02 --> 00:05:05 has re examined the original data using a
00:05:05 --> 00:05:07 more comprehensive approach. Rather than
00:05:07 --> 00:05:09 analysing data from each of Webb's
00:05:09 --> 00:05:11 instruments separately, Luke's team conducted
00:05:11 --> 00:05:14 a joint analysis using information from all
00:05:14 --> 00:05:16 three of the telescope's key instruments
00:05:16 --> 00:05:19 simultaneously. This approach ensures that
00:05:19 --> 00:05:20 scientists aren't telling what Luke's
00:05:20 --> 00:05:23 colleague Michael Jang calls contradictory
00:05:23 --> 00:05:26 stories about the same planet. When
00:05:26 --> 00:05:28 analysing the combined dataset, the
00:05:28 --> 00:05:30 researchers found that the signal for DMS or
00:05:30 --> 00:05:32 DMDs was much weaker than originally
00:05:32 --> 00:05:35 reported. So weak in fact, that they
00:05:35 --> 00:05:38 described it as statistically insignificant.
00:05:38 --> 00:05:41 As team member Caroline Piolet Gorayeb
00:05:41 --> 00:05:43 explained, we never saw more than
00:05:43 --> 00:05:45 insignificant hints of either DMS or
00:05:45 --> 00:05:48 DMDs, and even these hints were not present
00:05:48 --> 00:05:50 in all data reductions. Their work
00:05:50 --> 00:05:52 suggests that the spectral features observed
00:05:52 --> 00:05:54 could be explained by other molecules
00:05:54 --> 00:05:56 commonly found in exoplanet atmospheres that
00:05:57 --> 00:05:59 associated with life. This controversy
00:05:59 --> 00:06:01 highlights a ah, fundamental challenge in the
00:06:01 --> 00:06:04 search for extraterrestrial life. The
00:06:04 --> 00:06:05 chemical signatures of potential
00:06:05 --> 00:06:08 biosignatures like DMS are incredibly
00:06:08 --> 00:06:10 subtle and can be easily confused with more
00:06:10 --> 00:06:13 common molecules. For instance, the
00:06:13 --> 00:06:15 difference between DMS and ethane, a common
00:06:15 --> 00:06:17 non biological molecule in planetary
00:06:17 --> 00:06:20 atmospheres, is just one sulphur atom.
00:06:20 --> 00:06:22 While the Webb Telescope represents a quantum
00:06:22 --> 00:06:24 leap in our observational capabilities,
00:06:25 --> 00:06:27 distinguishing between molecules with such
00:06:27 --> 00:06:29 similar structures remains extremely
00:06:29 --> 00:06:31 difficult, especially across distances
00:06:31 --> 00:06:34 measured in light years. As Piule
00:06:34 --> 00:06:36 Goroyeb noted, until we can separate these
00:06:36 --> 00:06:38 signals more clearly, we have to be
00:06:38 --> 00:06:40 especially careful not to misinterpret them
00:06:40 --> 00:06:41 as signs of life.
00:06:42 --> 00:06:45 Okay, moving on to something a little more
00:06:45 --> 00:06:47 positive. Have you ever wondered how the
00:06:47 --> 00:06:50 light from stars billions of light years away
00:06:50 --> 00:06:52 manages to reach us without dimming into
00:06:52 --> 00:06:55 nothingness? This remarkable property
00:06:55 --> 00:06:57 of light was beautifully illustrated by an
00:06:57 --> 00:07:00 astrophysicist who captured images of the
00:07:00 --> 00:07:03 Pinwheel Galaxy from his San Diego backyard.
00:07:03 --> 00:07:05 When his wife asked if light gets tired
00:07:05 --> 00:07:07 during its 25 million year journey across
00:07:07 --> 00:07:10 150 quintillion miles of space, it
00:07:10 --> 00:07:12 sparked a fascinating exploration of light's
00:07:12 --> 00:07:15 extraordinary nature. Light is fundamentally
00:07:15 --> 00:07:17 different from anything we encounter in our
00:07:17 --> 00:07:19 everyday lives. As electromagnetic
00:07:19 --> 00:07:22 radiation, it consists of coupled electric
00:07:22 --> 00:07:24 and magnetic waves travelling through
00:07:24 --> 00:07:27 spacetime. What makes light truly special
00:07:27 --> 00:07:30 is that it has no mass whatsoever. This
00:07:30 --> 00:07:32 seemingly simple characteristic has profound
00:07:32 --> 00:07:34 implications for how light behaves across
00:07:35 --> 00:07:37 cosmic distances. Because light
00:07:37 --> 00:07:40 is massless, it's not constrained by the
00:07:40 --> 00:07:42 limitations that affect physical objects.
00:07:42 --> 00:07:44 While everything with mass can only approach
00:07:44 --> 00:07:47 but never reach light speed speed, Light
00:07:47 --> 00:07:49 itself travels at the universe's ultimate
00:07:49 --> 00:07:51 speed limit, approximately
00:07:51 --> 00:07:54 186 miles per second, or
00:07:54 --> 00:07:57 nearly 6 trillion miles per year. To put this
00:07:57 --> 00:07:59 incredible velocity into perspective, a
00:07:59 --> 00:08:01 single particle of light can circle our
00:08:01 --> 00:08:03 entire planet more than twice in the blink of
00:08:03 --> 00:08:06 an eye. When light travels unimpeded through
00:08:06 --> 00:08:08 the vacuum of space, it maintains this
00:08:08 --> 00:08:11 tremendous speed indefinitely without losing
00:08:11 --> 00:08:13 energy. This is counterintuitive to our
00:08:13 --> 00:08:15 everyday experience, where moving objects
00:08:15 --> 00:08:17 eventually slow down due to friction or other
00:08:17 --> 00:08:20 forces. But in the vast emptiness between
00:08:20 --> 00:08:23 stars and galaxies, there's simply nothing to
00:08:23 --> 00:08:26 slow light down. That's not to say that all
00:08:26 --> 00:08:29 light reaches us intact. Some photons do
00:08:29 --> 00:08:30 collide with interstellar dust particles or
00:08:30 --> 00:08:33 gas clouds along their journey, causing them
00:08:33 --> 00:08:36 to scatter or be absorbed. This is why
00:08:36 --> 00:08:38 distant celestial objects can appear dimmer
00:08:38 --> 00:08:40 or redder than they actually are, a
00:08:40 --> 00:08:42 phenomenon astronomers call extinction.
00:08:43 --> 00:08:45 However, the vast Majority of photons travel
00:08:45 --> 00:08:47 through the nearly perfect vacuum of space
00:08:48 --> 00:08:50 without encountering any obstacles
00:08:50 --> 00:08:52 whatsoever. This ability to maintain energy
00:08:52 --> 00:08:55 over immense distances is directly tied to
00:08:55 --> 00:08:58 Einstein's theory of relativity. According to
00:08:58 --> 00:09:00 this revolutionary framework, time itself
00:09:00 --> 00:09:02 behaves differently depending on your speed
00:09:02 --> 00:09:05 and proximity to gravitational fields. For
00:09:05 --> 00:09:08 objects moving at extreme velocities, time
00:09:08 --> 00:09:11 actually slows down. A phenomenon called time
00:09:11 --> 00:09:13 dilation that has been repeatedly confirmed
00:09:13 --> 00:09:16 through precision experiments. For light,
00:09:16 --> 00:09:18 this time dilation reaches its theoretical
00:09:18 --> 00:09:21 maximum. If you could somehow ride alongside
00:09:21 --> 00:09:23 a photon, Impossible. Since you have mass,
00:09:23 --> 00:09:26 you would experience something truly mind
00:09:26 --> 00:09:28 bending. From your perspective, time would
00:09:28 --> 00:09:30 completely stop. Meanwhile, space, in your
00:09:30 --> 00:09:32 direction of travel, would appear compressed
00:09:32 --> 00:09:35 to nothing. What we perceive as a journey of
00:09:35 --> 00:09:38 millions or billions of years would, from the
00:09:38 --> 00:09:39 photon's frame of reference, happen
00:09:40 --> 00:09:42 instantaneously. This
00:09:42 --> 00:09:44 peculiar relationship between light and
00:09:44 --> 00:09:46 spacetime explains how photons can travel
00:09:46 --> 00:09:48 such tremendous distances without
00:09:48 --> 00:09:51 degradation. From the photon's
00:09:51 --> 00:09:53 perspective, there is no journey at all,
00:09:53 --> 00:09:56 just instantaneous transport from source to
00:09:56 --> 00:09:59 destination. Now imagine yourself as a
00:09:59 --> 00:10:02 photon, a massless particle of light
00:10:02 --> 00:10:04 travelling at the universe's speed limit.
00:10:05 --> 00:10:07 From your perspective, something truly
00:10:07 --> 00:10:10 extraordinary, time completely stops.
00:10:10 --> 00:10:12 This isn't science fiction. It's a direct
00:10:12 --> 00:10:14 consequence of Einstein's theory of
00:10:14 --> 00:10:17 relativity that fundamentally changes how we
00:10:17 --> 00:10:20 must think about cosmic journeys. When we
00:10:20 --> 00:10:22 observe light from distant galaxies, we
00:10:22 --> 00:10:24 calculate travel times in the millions or
00:10:24 --> 00:10:27 billions of years. The photons reaching Earth
00:10:27 --> 00:10:29 from the Pinwheel Galaxy, for instance, have
00:10:29 --> 00:10:31 been travelling for 25 million years
00:10:31 --> 00:10:34 according to our earthbound clocks. But for
00:10:34 --> 00:10:37 the photon itself, this immense journey
00:10:37 --> 00:10:39 happens in an instant. Literally no time
00:10:39 --> 00:10:42 passes from its perspective. This mind
00:10:42 --> 00:10:45 bending reality occurs because as an object
00:10:45 --> 00:10:48 approaches the speed of light, time dilation
00:10:48 --> 00:10:50 becomes more pronounced. At exactly light
00:10:50 --> 00:10:52 speed, time dilation reaches its absolute
00:10:52 --> 00:10:55 maximum. If you could somehow attach a clock
00:10:55 --> 00:10:58 to a photon, which is physically impossible,
00:10:58 --> 00:11:01 that clock would never tick forward. The
00:11:01 --> 00:11:03 moment of emission and the moment of
00:11:03 --> 00:11:05 absorption would be the same moment. Even
00:11:05 --> 00:11:07 more strange is what happens to space from
00:11:07 --> 00:11:10 the photon's perspective. As, velocity
00:11:10 --> 00:11:13 increases, space itself contracts in the
00:11:13 --> 00:11:15 direction of travel. For a photon moving at
00:11:15 --> 00:11:17 light speed, this contraction becomes
00:11:17 --> 00:11:20 complete. The entire distance between source
00:11:20 --> 00:11:22 and destination essentially shrinks to zero.
00:11:23 --> 00:11:25 So while we see vast gulfs of space
00:11:25 --> 00:11:28 separating cosmic objects, from the photon's
00:11:28 --> 00:11:30 viewpoint, there is no separation at all.
00:11:31 --> 00:11:33 The star that emitted it and the telescope
00:11:33 --> 00:11:36 that detected it might be separated by
00:11:36 --> 00:11:37 billions of light years in our reference
00:11:37 --> 00:11:40 frame. But to the photon, they occupy the
00:11:40 --> 00:11:43 same point in spacetime. This reveals
00:11:43 --> 00:11:45 something profound about the nature of our
00:11:45 --> 00:11:47 universe. The cosmic speed limit isn't just
00:11:47 --> 00:11:50 an arbitrary rule, it's woven into the fabric
00:11:50 --> 00:11:53 of reality itself. As objects approach
00:11:53 --> 00:11:55 this limit, the very concepts of time and
00:11:55 --> 00:11:58 distance transform in ways that preserve the
00:11:58 --> 00:12:00 consistency of physical laws throughout the
00:12:00 --> 00:12:00 universe.
00:12:02 --> 00:12:05 Next on our agenda today, a UK based space
00:12:05 --> 00:12:07 propulsion startup called Pulsar Fusion has
00:12:07 --> 00:12:10 recently unveiled an ambitious concept that
00:12:10 --> 00:12:11 could revolutionise our approach to
00:12:11 --> 00:12:14 interplanetary travel. Their Sunbird
00:12:14 --> 00:12:16 migratory transfer vehicle represents a
00:12:16 --> 00:12:18 dramatic leap forward in space propulsion
00:12:18 --> 00:12:20 technology. Powered by what they call dual
00:12:20 --> 00:12:23 direct fusion drive engines, or DDFD for
00:12:23 --> 00:12:26 short. What makes this concept truly
00:12:26 --> 00:12:29 revolutionary is the projected speed.
00:12:29 --> 00:12:32 According to Pulsar Fusion, the Sunbird could
00:12:32 --> 00:12:35 achieve velocities of up to 329
00:12:35 --> 00:12:37 miles per hour. To put that in perspective,
00:12:38 --> 00:12:40 that's over 150 times faster than the
00:12:40 --> 00:12:42 International Space Station's orbital speed.
00:12:43 --> 00:12:46 If these projections hold true, the Sunbird
00:12:46 --> 00:12:47 would become the fastest self propelled
00:12:47 --> 00:12:49 object ever engineered by humans.
00:12:50 --> 00:12:52 The key to this extraordinary performance is
00:12:52 --> 00:12:55 nuclear fusion, the same process that powers
00:12:55 --> 00:12:58 our sun and other stars. Unlike conventional
00:12:58 --> 00:13:00 chemical rockets that have fundamental
00:13:00 --> 00:13:03 limitations on exhaust velocity, these fusion
00:13:03 --> 00:13:05 engines could produce exhaust speeds of
00:13:05 --> 00:13:07 approximately 310 miles per second,
00:13:08 --> 00:13:10 or about 500 kilometres per second.
00:13:11 --> 00:13:13 This represents a quantum leap beyond current
00:13:13 --> 00:13:16 propulsion capabilities. In a
00:13:16 --> 00:13:18 demonstration video, the company shows the
00:13:18 --> 00:13:20 Sunbird undocking from a space station,
00:13:20 --> 00:13:22 carefully manoeuvring with eight thrusters to
00:13:22 --> 00:13:25 attach to a larger spacecraft resembling a
00:13:25 --> 00:13:27 SpaceX Starship upper stage before igniting
00:13:27 --> 00:13:30 its main engines and accelerating toward
00:13:30 --> 00:13:32 distant planets. Of course, significant
00:13:32 --> 00:13:34 engineering challenges remain before this
00:13:34 --> 00:13:37 concept becomes reality. Pulsar Fusion
00:13:37 --> 00:13:38 acknowledges they're still in development,
00:13:39 --> 00:13:41 with plans to demonstrate essential
00:13:41 --> 00:13:43 components of the fusion power system later
00:13:43 --> 00:13:46 this year. They've set an ambitious target of
00:13:46 --> 00:13:48 2027 for full in orbit testing,
00:13:48 --> 00:13:50 a timeline that would mark a historic
00:13:50 --> 00:13:52 achievement in both aerospace engineering and
00:13:52 --> 00:13:55 energy technology. If successful, the
00:13:55 --> 00:13:57 implications for Mars exploration are
00:13:57 --> 00:14:00 particularly exciting. Current chemical
00:14:00 --> 00:14:02 propulsion systems require lengthy transit
00:14:02 --> 00:14:05 times to reach the Red planet, typically six
00:14:05 --> 00:14:07 to nine months, depending on planetary
00:14:07 --> 00:14:10 alignment. A fusion powered vehicle could
00:14:10 --> 00:14:11 potentially cut this journey time
00:14:11 --> 00:14:13 dramatically, making Mars missions more
00:14:13 --> 00:14:16 feasible from both human factors and
00:14:16 --> 00:14:18 logistical perspectives. Beyond Mars,
00:14:19 --> 00:14:21 the technology could enable more rapid
00:14:21 --> 00:14:23 exploration throughout the solar system.
00:14:24 --> 00:14:25 Missions to the outer planets that currently
00:14:25 --> 00:14:27 take years could be accomplished in months,
00:14:28 --> 00:14:30 opening new possibilities for scientific
00:14:30 --> 00:14:33 discovery and potentially even resource
00:14:33 --> 00:14:35 utilisation beyond Earth. What Pulsar
00:14:35 --> 00:14:38 Fusion is proposing isn't just an incremental
00:14:38 --> 00:14:40 improvement. It represents a fundamental
00:14:40 --> 00:14:43 shift in our capability to traverse the solar
00:14:43 --> 00:14:45 system, potentially transforming
00:14:45 --> 00:14:47 interplanetary space from a forbidding
00:14:47 --> 00:14:49 frontier into something more akin to a
00:14:49 --> 00:14:52 navigable ocean with established shipping
00:14:52 --> 00:14:54 lanes and regular traffic. The
00:14:54 --> 00:14:57 Versatility of the system appears to be a key
00:14:57 --> 00:14:59 selling point. Pulsar fusion envisions
00:14:59 --> 00:15:02 their technology powering missions ranging
00:15:02 --> 00:15:05 from deploying telescopes in deep space to
00:15:05 --> 00:15:07 transporting robotic probes throughout the
00:15:07 --> 00:15:10 solar system. As commercial interest in
00:15:10 --> 00:15:12 lunar and Martian resources continues to
00:15:12 --> 00:15:14 grow, having a reliable, relatively
00:15:14 --> 00:15:17 affordable transport system could accelerate
00:15:17 --> 00:15:19 development beyond Earth orbit. What's
00:15:19 --> 00:15:21 particularly interesting about this approach
00:15:21 --> 00:15:23 is how it mirrors historical patterns of
00:15:23 --> 00:15:26 transportation economics. Just as shipping
00:15:26 --> 00:15:28 containers revolutionised global trade by
00:15:28 --> 00:15:31 standardising cargo transport, these fusion
00:15:31 --> 00:15:33 powered spacecraft could create a
00:15:33 --> 00:15:35 standardised approach to moving materials
00:15:35 --> 00:15:38 beyond Earth. The establishment of regular
00:15:38 --> 00:15:41 shipping lanes between Earth lunar colonies,
00:15:41 --> 00:15:44 Mars outposts and even asteroid mining
00:15:44 --> 00:15:46 operations could create entirely new economic
00:15:46 --> 00:15:49 opportunities. Finally,
00:15:49 --> 00:15:51 today, I love this.
00:15:51 --> 00:15:53 In a beautiful intersection of classical
00:15:53 --> 00:15:56 music and space exploration, Johann Strauss's
00:15:56 --> 00:15:59 iconic composition the Blue Danube will soon
00:15:59 --> 00:16:02 be travelling among the stars. This month,
00:16:02 --> 00:16:04 to commemorate the 200th anniversary of the
00:16:04 --> 00:16:07 Austrian composer's birth, his famous waltz
00:16:07 --> 00:16:10 will be beamed into the cosmos in a special
00:16:10 --> 00:16:12 transmission organised by the European Space
00:16:12 --> 00:16:15 Agency. The celestial performance will
00:16:15 --> 00:16:17 feature the Vienna Symphony Orchestra with
00:16:17 --> 00:16:19 their rendition of the beloved waltz being
00:16:19 --> 00:16:22 converted into radio signals and transmitted
00:16:22 --> 00:16:25 from Earth on May 31st. This
00:16:25 --> 00:16:28 cosmic concert also serves as a celebration
00:16:28 --> 00:16:30 of the European Space Agency's 50th
00:16:30 --> 00:16:33 anniversary, creating a meaningful connection
00:16:33 --> 00:16:35 between artistic heritage and scientific
00:16:35 --> 00:16:38 achievement. While the performance will be
00:16:38 --> 00:16:40 live streamed, with public screenings in
00:16:40 --> 00:16:42 Vienna, Madrid and New York, ESA
00:16:42 --> 00:16:45 is taking no chances with the actual space
00:16:45 --> 00:16:47 transmission. They'll relay a pre recorded
00:16:47 --> 00:16:49 version from the orchestra's rehearsal to
00:16:49 --> 00:16:52 ensure technical perfection. While the live
00:16:52 --> 00:16:53 orchestral performance provides the
00:16:53 --> 00:16:56 Earthbound accompaniment, the radio
00:16:56 --> 00:16:58 signals carrying Strauss's masterpiece will
00:16:58 --> 00:17:00 depart Earth at the speed of light, an
00:17:00 --> 00:17:03 astonishing 670 million miles per hour.
00:17:04 --> 00:17:06 This means the waltz that once accompanied
00:17:06 --> 00:17:09 dancers across European ballrooms will hurtle
00:17:09 --> 00:17:11 past our moon in just one and a half seconds.
00:17:11 --> 00:17:14 It's a fitting cosmic journey for a piece
00:17:14 --> 00:17:16 that many associate with space. Thanks to its
00:17:16 --> 00:17:19 memorable appearance in Stanley Kubrick's
00:17:19 --> 00:17:22 2001 A, Space Odyssey, the M
00:17:22 --> 00:17:23 transmission represents something of a
00:17:23 --> 00:17:26 correction to a historical oversight.
00:17:27 --> 00:17:29 When NASA launched the voyager probes in
00:17:29 --> 00:17:32 1977, with their famous golden records
00:17:32 --> 00:17:34 containing sounds and music of Earth,
00:17:34 --> 00:17:37 Strauss's compositions were notably absent.
00:17:37 --> 00:17:40 Despite their cultural significance, Vienna's
00:17:40 --> 00:17:42 tourist board has characterised this
00:17:42 --> 00:17:44 transmission as rectifying that
00:17:45 --> 00:17:48 cosmic mistake, finally giving the Blue
00:17:48 --> 00:17:50 Danube its rightful place among the stars,
00:17:51 --> 00:17:54 ESA will use its powerful radio antenna in
00:17:54 --> 00:17:56 Spain, part of the agency's deep space
00:17:56 --> 00:17:59 network, to transmit the waltz. In a poetic
00:17:59 --> 00:18:00 touch, the dish will be pointed toward
00:18:00 --> 00:18:03 Voyager 1's location, sending Strauss's music
00:18:03 --> 00:18:05 In the direction of humanity's most distant
00:18:05 --> 00:18:08 spacecraft, this musical mission
00:18:08 --> 00:18:10 joins a tradition of transmitting human
00:18:10 --> 00:18:13 artistic achievements into space. In
00:18:13 --> 00:18:15 previous years, NASA has beamed the Beatles
00:18:15 --> 00:18:18 across the universe and Missy Elliott's the
00:18:18 --> 00:18:20 Rain toward distant celestial bodies,
00:18:21 --> 00:18:23 while the Mars rover Curiosity even relayed
00:18:23 --> 00:18:26 Will iam's reach for the stars back to
00:18:26 --> 00:18:29 Earth from the Red Planet. As ESA Director
00:18:29 --> 00:18:31 General Josef Aschbacher noted, music
00:18:31 --> 00:18:34 connects us all through time and space in a
00:18:34 --> 00:18:36 very particular way. In sending this timeless
00:18:36 --> 00:18:39 composition beyond our world, humanity
00:18:39 --> 00:18:40 continues its practise of sharing our
00:18:40 --> 00:18:43 cultural treasures with the cosmos. A gesture
00:18:43 --> 00:18:45 of artistic connection that extends far
00:18:45 --> 00:18:48 beyond the boundaries of Earth. The radio
00:18:48 --> 00:18:50 signals carrying Strauss's waltz will travel
00:18:50 --> 00:18:53 at truly cosmic speeds, racing through our
00:18:53 --> 00:18:55 solar system and beyond. After passing the
00:18:55 --> 00:18:58 moon in just 1.5 seconds, the beautiful
00:18:58 --> 00:19:01 melodies will reach Mars in only 4.5 minutes.
00:19:02 --> 00:19:04 Within 37 minutes, Jupiter will hear the
00:19:04 --> 00:19:07 waltz. And by the four hour mark, the music
00:19:07 --> 00:19:09 will have travelled beyond Neptune at the
00:19:09 --> 00:19:11 edge of our solar system. Perhaps most
00:19:11 --> 00:19:13 remarkably, within just 23 hours,
00:19:13 --> 00:19:15 Strauss's composition will have travelled as
00:19:15 --> 00:19:18 far from Earth as Voyager 1, humanity's
00:19:18 --> 00:19:21 most distant spacecraft. Currently over 15
00:19:21 --> 00:19:24 billion miles away in interstellar space,
00:19:24 --> 00:19:26 music has even flowed in the opposite
00:19:26 --> 00:19:29 direction. In 2012, NASA's
00:19:29 --> 00:19:32 Curiosity rover on Mars received will die
00:19:32 --> 00:19:34 AM's reach for the stars and then relayed it
00:19:34 --> 00:19:36 back to Earth, creating the first
00:19:36 --> 00:19:38 interplanetary musical transmission from
00:19:38 --> 00:19:41 another world. Unlike the routine melodies
00:19:41 --> 00:19:43 streamed between mission control and orbiting
00:19:43 --> 00:19:46 Crews since the mid-1960s, these
00:19:46 --> 00:19:49 deep space transmissions represent deliberate
00:19:49 --> 00:19:50 attempts to share human culture with the
00:19:50 --> 00:19:53 cosmos. Whether anyone or anything will
00:19:53 --> 00:19:55 ever receive these musical messages remains
00:19:55 --> 00:19:58 unknown. But the gesture itself represents
00:19:58 --> 00:20:00 humanity's persistent desire to connect
00:20:00 --> 00:20:02 across the vastness of space.
00:20:04 --> 00:20:06 What a journey we've taken today across the
00:20:06 --> 00:20:09 cosmos. From the microscopic to the
00:20:09 --> 00:20:11 musical, our exploration reminds us that
00:20:11 --> 00:20:13 space science continues to surprise and
00:20:13 --> 00:20:16 inspire us in equal measure. The
00:20:16 --> 00:20:18 stories we've explored today span from
00:20:18 --> 00:20:20 bacterial adaptations to cosmic musical
00:20:20 --> 00:20:22 performances. Yet they all share a common
00:20:22 --> 00:20:25 thread. Human curiosity. Our
00:20:25 --> 00:20:28 desire to understand, to explore, and to
00:20:28 --> 00:20:30 connect across the vastness of space
00:20:30 --> 00:20:32 continues to drive us forward into an
00:20:32 --> 00:20:35 exciting future among the stars. Thank you

00:20:46 --> 00:20:48 something fascinating happening in our
00:20:48 --> 00:20:49 universe.
