AnnaAnnaHost
China launches three astronauts to Tiangong — including Hong Kong's first-ever taikonaut — on a mission that breaks multiple records. NASA's Psyche probe delivers breathtaking imagery from its Mars flyby. A bizarre 19-day solar radio burst finally gets an explanation. Scientists zero in on the source of the most powerful neutrino ever detected. Two dead stars orbit each other in less than nine minutes. And researchers propose using fungi to turn Martian soil into farmland. It's a big Monday on Astronomy Daily.Story Timestamps

00:00:00 --> 00:00:02 Anna: Hello and welcome to Astronomy Daily,

00:00:02 --> 00:00:05 your Monday briefing on everything happening

00:00:05 --> 00:00:07 across the cosmos. I'm Anna.

00:00:08 --> 00:00:10 Avery: And I'm Avery. It is Monday 25th

00:00:10 --> 00:00:13 May, 2026, and we have a packed show

00:00:13 --> 00:00:14 for you today.

00:00:14 --> 00:00:17 Anna: We do. Uh, coming up, China makes history

00:00:18 --> 00:00:20 with a crew launch that breaks several

00:00:20 --> 00:00:22 records at once. NASA's Psyche

00:00:22 --> 00:00:25 spacecraft wows us with brand new imagery

00:00:25 --> 00:00:28 from Mars. And the sun served up a

00:00:28 --> 00:00:30 signal so bizarre, scientists are staring,

00:00:30 --> 00:00:31 still scratching their heads.

00:00:32 --> 00:00:35 Avery: Plus ghost particles from a cosmic monster,

00:00:35 --> 00:00:37 A stellar feeding frenzy in an orbit that's

00:00:37 --> 00:00:40 almost impossibly fast, and the

00:00:40 --> 00:00:42 surprisingly hopeful story about farming on

00:00:42 --> 00:00:44 Mars. Let's get into it.

00:00:44 --> 00:00:47 Anna: China made history on Sunday night, launching

00:00:47 --> 00:00:49 three astronauts to its Tiangong space

00:00:49 --> 00:00:52 station aboard the Shenzhou 23

00:00:52 --> 00:00:55 spacecraft. And this crew is carrying

00:00:55 --> 00:00:57 several firsts with them into orbit.

00:00:57 --> 00:01:00 Avery: The long March 2F rocket blasted off from the

00:01:00 --> 00:01:02 Zhuoquan Satellite launch Center in the Gobi

00:01:02 --> 00:01:05 Desert at, uh, just after 11pm Beijing time,

00:01:05 --> 00:01:08 sending the crew on their way to what China

00:01:08 --> 00:01:09 calls the Heavenly Palace.

00:01:10 --> 00:01:12 Anna: The crew consists of Mission commander Xu

00:01:12 --> 00:01:15 Yangzhou, pilot Zhang Zhiyuan,

00:01:15 --> 00:01:18 and payload specialist Lai Kaying.

00:01:18 --> 00:01:21 And it's Lai who's making the history books.

00:01:21 --> 00:01:23 She was born and raised in Hong Kong and

00:01:23 --> 00:01:26 holds a doctorate in computer forensics. She

00:01:26 --> 00:01:29 is the very first astronaut from Hong Kong to

00:01:29 --> 00:01:29 reach space.

00:01:30 --> 00:01:33 Avery: That's a genuinely big moment, Anna. Um, Hong

00:01:33 --> 00:01:35 Kong has been growing its contributions to

00:01:35 --> 00:01:37 China's space program significantly in recent

00:01:37 --> 00:01:39 years, with university teams developing

00:01:39 --> 00:01:42 instruments for upcoming lunar missions. To

00:01:42 --> 00:01:44 now have someone from the city actually

00:01:44 --> 00:01:46 flying, that's a real milestone.

00:01:46 --> 00:01:49 Anna: And the historic firsts don't stop there.

00:01:49 --> 00:01:52 One member of the Shenzhou 23 crew will stay

00:01:52 --> 00:01:55 aboard Tiangong for a full year to the

00:01:55 --> 00:01:57 first time any Chinese astronaut has

00:01:57 --> 00:01:59 undertaken a 12 month mission.

00:01:59 --> 00:02:01 Avery: The extended stay is connected to a

00:02:01 --> 00:02:03 fascinating plan for the Follow up

00:02:03 --> 00:02:05 shenzhou24Mission due later this year.

00:02:06 --> 00:02:08 That mission will carry a Pakistani

00:02:08 --> 00:02:10 astronaut, the first international visitor to

00:02:10 --> 00:02:12 China space station, who will spend a short

00:02:12 --> 00:02:15 time aboard before returning on the outbound

00:02:15 --> 00:02:17 Shenzhou 23 vehicle, leaving one of the

00:02:17 --> 00:02:20 current crew to complete that year long stay.

00:02:20 --> 00:02:22 Anna: It's a clever piece of mission architecture,

00:02:22 --> 00:02:25 and all of it is building toward China's

00:02:25 --> 00:02:27 stated goal of a crewed lunar landing by

00:02:27 --> 00:02:30 2030. Every long duration mission,

00:02:30 --> 00:02:33 every new crew rotation, is laying the

00:02:33 --> 00:02:35 groundwork for those much longer future

00:02:35 --> 00:02:35 missions.

00:02:36 --> 00:02:38 Avery: The new crew will also relieve the Shenzhou

00:02:38 --> 00:02:41 21 astronauts who've been aboard Tiangong for

00:02:41 --> 00:02:43 more than 200 days, slightly longer than

00:02:43 --> 00:02:46 originally planned following an incident last

00:02:46 --> 00:02:48 year where their Return spacecraft was

00:02:48 --> 00:02:50 damaged by suspected debris. They'll be very

00:02:50 --> 00:02:52 glad to see a fresh crew arrive.

00:02:53 --> 00:02:55 Anna: Congratulations to Xu Yongzhu, Zhong

00:02:55 --> 00:02:58 Zhiyuan and especially Lai Kai Ying

00:02:58 --> 00:03:00 on this historic mission. We'll be following

00:03:00 --> 00:03:03 their time aboard Tiangong closely now.

00:03:03 --> 00:03:05 Avery: Remember a couple of weeks ago we told you

00:03:05 --> 00:03:08 about NASA's Psyche spacecraft preparing to

00:03:08 --> 00:03:10 slingshot around Mars on its way to the

00:03:10 --> 00:03:13 asteroid belt. Well, the images are in

00:03:13 --> 00:03:15 and they are spectacular.

00:03:15 --> 00:03:17 Anna: NASA released the photos this week from

00:03:17 --> 00:03:19 Psyche's gravity assist flyby, uh, of Mars.

00:03:19 --> 00:03:22 On 15 May. The spacecraft came within just

00:03:22 --> 00:03:25 under 2 miles of the Martian surface,

00:03:25 --> 00:03:28 traveling, uh, at more than 12 miles an

00:03:28 --> 00:03:30 hour. And its multispectral imager was

00:03:30 --> 00:03:32 working overtime.

00:03:32 --> 00:03:34 Avery: The standout image shows the Huygens crater,

00:03:34 --> 00:03:37 a massive double ringed impact structure

00:03:37 --> 00:03:39 nearly 300 miles across in Mars's

00:03:39 --> 00:03:42 southern highlands. Psyche enhanced the

00:03:42 --> 00:03:44 colors to highlight compositional differences

00:03:44 --> 00:03:47 in the dust, sand and bedrock.

00:03:47 --> 00:03:50 And the result is genuinely beautiful. Ochres

00:03:50 --> 00:03:53 and tans and pale blues against the ancient

00:03:53 --> 00:03:54 cratered terrain.

00:03:54 --> 00:03:57 Anna: These images serve a, uh, real scientific

00:03:57 --> 00:04:00 purpose. Beyond the stunning visuals,

00:04:00 --> 00:04:03 they're calibration data for Psyche's imaging

00:04:03 --> 00:04:05 instruments. The first chance the science

00:04:05 --> 00:04:08 team has had to test them against an object

00:04:08 --> 00:04:11 larger than a few pixels. That's

00:04:11 --> 00:04:13 going to be crucial when the spacecraft

00:04:13 --> 00:04:15 finally arrives at its target.

00:04:16 --> 00:04:18 Avery: And Mars delivered the goods dynamically as

00:04:18 --> 00:04:21 well. The flyby gave Psyche a speed boost of

00:04:21 --> 00:04:24 around 1 miles per hour and shifted its

00:04:24 --> 00:04:27 orbital plane, all without burning a drop of

00:04:27 --> 00:04:29 onboard propellant. The navigation team

00:04:29 --> 00:04:31 confirmed a spacecraft is now on a direct

00:04:31 --> 00:04:34 course for the asteroid, with arrival

00:04:34 --> 00:04:36 expected in August 2029.

00:04:36 --> 00:04:39 Anna: Asteroid 16 Psyche, of course,

00:04:39 --> 00:04:42 is one of the most intriguing objects in the

00:04:42 --> 00:04:45 solar system. Uh, a metallic world that may

00:04:45 --> 00:04:48 be the exposed core of a protoplanet

00:04:48 --> 00:04:50 and potentially worth more than the entire

00:04:51 --> 00:04:53 global economy in precious metals.

00:04:53 --> 00:04:56 Though we should note that last part is very

00:04:56 --> 00:04:58 much a theoretical figure.

00:04:58 --> 00:05:01 Avery: Still, it's quite a headline. Gorgeous

00:05:01 --> 00:05:03 images. Now the asteroid itself in three

00:05:03 --> 00:05:05 years time. Well worth the wait.

00:05:06 --> 00:05:08 Anna: Here's a solar physics story that genuinely

00:05:08 --> 00:05:11 surprised researchers. Back In August of

00:05:11 --> 00:05:14 2025, NASA's instruments

00:05:14 --> 00:05:16 picked up what initially looked like a

00:05:16 --> 00:05:19 perfectly routine radio burst from the sun.

00:05:19 --> 00:05:22 Avery: Except it didn't stop Exactly.

00:05:22 --> 00:05:25 Anna: These type 4 solar radio

00:05:25 --> 00:05:28 bursts, produced when energetic electrons

00:05:28 --> 00:05:31 get trapped inside the Sun's magnetic fields,

00:05:31 --> 00:05:34 normally last anywhere from a few hours to

00:05:34 --> 00:05:36 maybe a few days. The previous record

00:05:37 --> 00:05:38 stood at five days.

00:05:38 --> 00:05:41 Avery: This one lasted 19, nearly

00:05:41 --> 00:05:44 four times the previous record. That's not a

00:05:44 --> 00:05:46 small anomaly. That's a completely different

00:05:46 --> 00:05:47 Class of event.

00:05:48 --> 00:05:50 Anna: The tricky part was actually tracking it,

00:05:50 --> 00:05:53 because as the sun rotates, different

00:05:53 --> 00:05:55 spacecraft had it in view at different times.

00:05:56 --> 00:05:58 A fleet of four missions pieced the

00:05:58 --> 00:06:01 Kickstarter, NASA's Parker Solar

00:06:01 --> 00:06:03 Probe, the STEREO mission, the WIND

00:06:03 --> 00:06:06 spacecraft, and the joint ESA

00:06:06 --> 00:06:09 NASA Solar Orbiter each observed

00:06:09 --> 00:06:11 the burst for several days across three

00:06:11 --> 00:06:13 overlapping windows.

00:06:14 --> 00:06:16 Avery: So it was almost like relay baton passing

00:06:16 --> 00:06:19 across a solar system. One spacecraft would

00:06:19 --> 00:06:21 watch the signal fade from its perspective,

00:06:21 --> 00:06:23 and then another on the other side would pick

00:06:23 --> 00:06:25 it up again as the sun rotated.

00:06:26 --> 00:06:28 Anna: Using data from stereo, the team

00:06:28 --> 00:06:31 developed a new tracking technique that

00:06:31 --> 00:06:33 pinpointed the source, a structure in the

00:06:33 --> 00:06:36 Sun's corona called a helmet streamer.

00:06:36 --> 00:06:39 These funnel shaped features form when hot

00:06:39 --> 00:06:42 plasma gets trapped along enormous

00:06:42 --> 00:06:44 magnetic loops extending outward from the

00:06:44 --> 00:06:45 Sun's surface.

00:06:46 --> 00:06:48 Avery: And the leading theory for why this one

00:06:48 --> 00:06:50 lasted so long was that three successive

00:06:50 --> 00:06:53 coronal mass ejections within the same region

00:06:53 --> 00:06:56 of the sun essentially kept re energizing the

00:06:56 --> 00:06:58 burst like someone repeatedly topping up a

00:06:58 --> 00:06:59 fire.

00:06:59 --> 00:07:01 Anna: The findings have been published in the

00:07:01 --> 00:07:04 Astrophysical Journal Letters, and the

00:07:04 --> 00:07:06 implications for space weather forecasting

00:07:06 --> 00:07:09 are significant. While the radio waves

00:07:09 --> 00:07:11 themselves are harmless, the magnetic

00:07:11 --> 00:07:14 environments that produce these bursts can

00:07:14 --> 00:07:17 also accelerate dangerous particles toward

00:07:17 --> 00:07:19 Earth. Particles that can damage satellites

00:07:19 --> 00:07:22 and spacecraft. Understanding how these

00:07:22 --> 00:07:25 bursts work and how long they can last is

00:07:25 --> 00:07:27 directly relevant to protecting our

00:07:27 --> 00:07:28 infrastructure in space.

00:07:29 --> 00:07:32 Avery: And with solar activity intensifying through

00:07:32 --> 00:07:34 the current cycle, the timing of this

00:07:34 --> 00:07:35 research couldn't be better.

00:07:36 --> 00:07:38 Anna: Now we're going deep. Very deep.

00:07:39 --> 00:07:41 Two miles below the surface of the

00:07:41 --> 00:07:44 Mediterranean Sea, off the coast of Sicily,

00:07:44 --> 00:07:47 sits one of the most unusual telescopes

00:07:47 --> 00:07:49 ever built. It's called KM

00:07:49 --> 00:07:52 M3Net, and it doesn't look at light.

00:07:52 --> 00:07:54 Avery: It hunts ghost particles,

00:07:55 --> 00:07:57 neutrinos, subatomic particles so

00:07:57 --> 00:08:00 small, so elusive, that a light year of

00:08:00 --> 00:08:03 solid lead would only have a fixed 5050

00:08:03 --> 00:08:05 chance of stopping one. Trillions of them are

00:08:05 --> 00:08:07 passing through your body right now without

00:08:07 --> 00:08:09 you feeling a thing.

00:08:09 --> 00:08:12 Anna: Back in February 2023,

00:08:12 --> 00:08:14 KM3Net detected something

00:08:14 --> 00:08:17 extraordinary. A neutrino with an

00:08:17 --> 00:08:20 energy of 220PETA

00:08:20 --> 00:08:22 electron volts. To put that in context,

00:08:23 --> 00:08:25 that's more than 30 times the energy of the

00:08:25 --> 00:08:28 most powerful neutrino ever previously

00:08:28 --> 00:08:31 recorded. A ping pong ball dropping 1

00:08:31 --> 00:08:34 meter carries about the same energy

00:08:34 --> 00:08:36 packed into a single subatomic

00:08:36 --> 00:08:37 particle.

00:08:37 --> 00:08:39 Avery: Scientists have been trying to work out where

00:08:39 --> 00:08:42 this particle came from ever since. And

00:08:42 --> 00:08:45 now, fresh research published this week in

00:08:45 --> 00:08:48 the Journal of Cosmology and Astrophysics

00:08:48 --> 00:08:50 points to a culprit. Lazars.

00:08:51 --> 00:08:54 Anna: Lasers are among the most violent objects in

00:08:54 --> 00:08:57 the universe. They're active galactic nuclei,

00:08:57 --> 00:08:59 effectively supermassive black holes that are

00:08:59 --> 00:09:02 shooting jets of plasma directly toward Earth

00:09:02 --> 00:09:05 from billions of light years away. They're

00:09:05 --> 00:09:07 cosmic particle accelerators on an almost

00:09:07 --> 00:09:09 incomprehensible scale.

00:09:09 --> 00:09:12 Avery: If the KM3 NET team's interpretation is

00:09:12 --> 00:09:14 confirmed that this record shattering

00:09:14 --> 00:09:16 neutrino originated from a population of

00:09:16 --> 00:09:19 blazars, it would completely rewrite our

00:09:19 --> 00:09:22 understanding of how these objects accelerate

00:09:22 --> 00:09:25 particles. It implies that blazars can push

00:09:25 --> 00:09:28 matter to energies far beyond what scientists

00:09:28 --> 00:09:29 previously thought possible.

00:09:29 --> 00:09:32 Anna: And the story isn't finished yet.

00:09:32 --> 00:09:35 Hem3net is still under construction.

00:09:35 --> 00:09:37 This detection arrived when only a fraction

00:09:37 --> 00:09:40 of the final instrument was operational. As

00:09:40 --> 00:09:42 the detector expands, it should catch more of

00:09:42 --> 00:09:45 these ultra high energy events, potentially

00:09:45 --> 00:09:47 narrowing down the source to a specific

00:09:47 --> 00:09:49 object or class of objects.

00:09:49 --> 00:09:51 Avery: A ghost particle from the edge of the

00:09:51 --> 00:09:54 universe, decoded by a telescope on the

00:09:54 --> 00:09:57 ocean floor. This is exactly the kind

00:09:57 --> 00:09:59 of story that reminds you why particle

00:09:59 --> 00:10:01 astrophysics is so extraordinary.

00:10:02 --> 00:10:05 Anna: Our next story comes from mit and it involves

00:10:05 --> 00:10:07 one of the most extreme gravitational dances

00:10:07 --> 00:10:10 ever observed. Two dead stars locked in

00:10:10 --> 00:10:13 an orbit so tight, so fast, it almost

00:10:13 --> 00:10:14 defies belief.

00:10:14 --> 00:10:16 Avery: We're, we're talking about a binary white

00:10:16 --> 00:10:19 dwarf system. White dwarfs are the remnant

00:10:19 --> 00:10:22 cores of stars like our Sun. Extremely dense,

00:10:22 --> 00:10:25 roughly Earth sized, but retaining the mass

00:10:25 --> 00:10:28 of a full star. When two of them end up

00:10:28 --> 00:10:30 orbiting each other at uh, very close range,

00:10:30 --> 00:10:32 remarkable things can happen.

00:10:32 --> 00:10:34 Anna: In this case, the two white dwarfs are

00:10:34 --> 00:10:36 orbiting each other with a period of just

00:10:36 --> 00:10:39 8.56 minutes. To put that in

00:10:39 --> 00:10:41 perspective, the Earth takes

00:10:41 --> 00:10:43 365 days to orbit the Sun.

00:10:44 --> 00:10:46 These two stellar corpses are completing a

00:10:46 --> 00:10:48 full orbit in less than nine minutes.

00:10:49 --> 00:10:51 Avery: At uh, that proximity, gravity becomes

00:10:51 --> 00:10:54 overwhelming. One of the white dwarfs is

00:10:54 --> 00:10:56 actively stripping material from the other,

00:10:56 --> 00:10:59 pulling it apart and devouring it in what

00:10:59 --> 00:11:01 astronomers call a, uh, mass transfer. It's

00:11:01 --> 00:11:04 essentially a slow motion cosmic cannibalism.

00:11:05 --> 00:11:08 Anna: Led by emma Chikls at MIT's Kavli Institute,

00:11:08 --> 00:11:10 the research team says this gives us one of

00:11:10 --> 00:11:13 the clearest news yet of how ultra compact

00:11:13 --> 00:11:16 white dwarf binaries exchange mass at such

00:11:16 --> 00:11:18 extreme orbital periods. Previous

00:11:18 --> 00:11:20 observations of these systems have been

00:11:20 --> 00:11:23 limited, and many fundamental questions about

00:11:23 --> 00:11:25 how violent mass transfer can get in such

00:11:25 --> 00:11:28 tight orbits have remained unanswered.

00:11:28 --> 00:11:30 Avery: There's another dimension to this discovery

00:11:30 --> 00:11:32 that's particularly exciting for the future

00:11:32 --> 00:11:35 of astronomy. Systems like this one are

00:11:35 --> 00:11:37 prime targets for next generation

00:11:37 --> 00:11:40 gravitational wave detectors, space based

00:11:40 --> 00:11:42 observatories that will be able to detect the

00:11:42 --> 00:11:45 ripples in space time produced by these

00:11:45 --> 00:11:47 ultra compact binaries.

00:11:47 --> 00:11:49 Anna: So what we're seeing here isn't just a

00:11:49 --> 00:11:52 fascinating stellar spectacle. It's a

00:11:52 --> 00:11:54 signpost pointing toward gravitational

00:11:54 --> 00:11:57 astronomy. The tighter the orbit, the more

00:11:57 --> 00:11:59 intense the gravitational signal. And at

00:11:59 --> 00:12:01 eight and a half minutes, this system is

00:12:01 --> 00:12:04 generating waves that future detectors should

00:12:04 --> 00:12:05 be able to pick up directly.

00:12:06 --> 00:12:07 Avery: The findings are published in the

00:12:07 --> 00:12:10 Astrophysical. Even burnt out stellar

00:12:10 --> 00:12:13 cores, it turns out, can be torn apart under

00:12:13 --> 00:12:15 the right circumstances. Space is

00:12:15 --> 00:12:16 metal.

00:12:16 --> 00:12:18 Anna: It really, really is.

00:12:18 --> 00:12:20 Avery: We're going to close today's episode with

00:12:20 --> 00:12:23 something that feels almost like science

00:12:23 --> 00:12:25 fiction, but is very much science fact.

00:12:25 --> 00:12:28 If humans are ever going to live on Mars long

00:12:28 --> 00:12:31 term, they're going to need to eat. And that

00:12:31 --> 00:12:33 means growing food. But Martian soil, or

00:12:33 --> 00:12:36 regolith, to use the correct term, is

00:12:36 --> 00:12:39 toxic, nutrient, dead, and about as

00:12:39 --> 00:12:41 welcoming to plant life as a car park.

00:12:42 --> 00:12:44 Anna: Not for long, if researchers from the United

00:12:44 --> 00:12:46 States and Brazil have their way. Their new

00:12:46 --> 00:12:49 study, published in Frontiers in Astronomy

00:12:49 --> 00:12:52 and Space Sciences, proposes a biological

00:12:52 --> 00:12:53 solution. Fungi.

00:12:54 --> 00:12:56 Avery: Specifically, a group called beneficial

00:12:56 --> 00:12:58 fungi, organisms that have been promoting

00:12:58 --> 00:13:00 plant growth on Earth since long before

00:13:00 --> 00:13:03 humans arrived. The key players here are

00:13:03 --> 00:13:06 arbuscular mycorrhizal fungi, or

00:13:06 --> 00:13:09 amf, which work by essentially acting as

00:13:09 --> 00:13:11 a microscopic extension of a plant's root

00:13:11 --> 00:13:14 system, dramatically increasing its ability

00:13:14 --> 00:13:15 to absorb nutrients.

00:13:16 --> 00:13:18 Anna: Martian regolith is critically deficient in

00:13:18 --> 00:13:20 three things plants need above, um, almost

00:13:20 --> 00:13:23 everything nitrogen, potassium, and

00:13:23 --> 00:13:26 phosphorus. It's also highly alkaline,

00:13:26 --> 00:13:28 perchlorate laden, and lacks the organic

00:13:28 --> 00:13:31 matter that makes Earth soil biologically

00:13:31 --> 00:13:33 active. The researchers propose that

00:13:33 --> 00:13:36 AMF and a related fungal species called

00:13:36 --> 00:13:39 Trichoderma could begin to overcome those

00:13:39 --> 00:13:42 deficiencies and transform the regolith into

00:13:42 --> 00:13:43 something biologically workable.

00:13:44 --> 00:13:46 Avery: What makes this particularly interesting is

00:13:46 --> 00:13:48 that these fungi have already been tested in

00:13:48 --> 00:13:51 space environments. Fungal species have been

00:13:51 --> 00:13:53 used on the International Space Station, and

00:13:53 --> 00:13:55 researchers are building an understanding of

00:13:55 --> 00:13:58 how they perform under the kind of abiotic

00:13:58 --> 00:14:00 stress, extreme temperatures, radiation,

00:14:01 --> 00:14:04 nutrient poverty that any organism on

00:14:04 --> 00:14:04 Mars would face.

00:14:05 --> 00:14:06 Anna: The team is candid that significant

00:14:07 --> 00:14:09 challenges remain before you're growing wheat

00:14:09 --> 00:14:12 in Martian regolith. Real world testing with

00:14:12 --> 00:14:15 actual Martian soil samples rather than

00:14:15 --> 00:14:17 simulants hasn't happened yet. But they're

00:14:17 --> 00:14:19 optimistic, and they frame this approach as a

00:14:19 --> 00:14:22 strategic biotechnological tool for what's

00:14:22 --> 00:14:24 called in situ resource utilization.

00:14:25 --> 00:14:26 Living off the land.

00:14:26 --> 00:14:29 Avery: The concept being, instead of shipping soil

00:14:29 --> 00:14:31 from Earth, which would be extraordinarily

00:14:31 --> 00:14:34 expensive and logistically nightmarish, and

00:14:34 --> 00:14:36 you bring a handful of carefully chosen

00:14:36 --> 00:14:38 microorganisms and let them do the

00:14:38 --> 00:14:41 terraforming at the microscale. Turn poison

00:14:41 --> 00:14:44 into farmland. One fungal threat at a

00:14:44 --> 00:14:44 time.

00:14:44 --> 00:14:47 Anna: It's patient science, but it's the kind of

00:14:47 --> 00:14:49 patient science that makes long duration Mars

00:14:49 --> 00:14:52 missions and eventually permanent human

00:14:52 --> 00:14:55 settlement imaginable. We'll be watching this

00:14:55 --> 00:14:56 research closely.

00:14:56 --> 00:14:58 Avery: And that's our Monday edition of Astronomy

00:14:58 --> 00:15:01 Daily, six stories from across the cosmos,

00:15:01 --> 00:15:03 from the launch pads of the Gobi Desert to

00:15:03 --> 00:15:06 the ocean floor of Sicily, from the surface

00:15:06 --> 00:15:08 of Mars to the edge of the observable

00:15:08 --> 00:15:08 universe.
