00:02Something unusual has been spotted on the Moon.
00:05And it's getting attention for a reason.
00:08New high-resolution observations linked to NASA's Artemis program
00:12revealed areas where the lunar surface appears to have shifted, cracked, or partially collapsed.
00:19In some images, it even looks like a section of the Moon has broken away.
00:24At first glance, this sounds extreme.
00:26The Moon is usually described as geologically inactive, a stable and unchanging world.
00:33But the data tells a different story.
00:36Certain regions now show surface features that were not clearly visible in older imagery,
00:42suggesting relatively recent changes.
00:45The key to understanding this lies in how the Moon actually evolves.
00:51Even without plate tectonics like Earth, the Moon is still slowly changing.
00:56One of the main reasons is temperature.
00:59The lunar surface experiences extreme swings from about 120 degree by 6 during the day to 130 degree by 6
01:07at night.
01:08These rapid changes cause the surface material to expand and contract over and over again,
01:15gradually weakening rock structures.
01:17Over time, this leads to cracking.
01:21Another major factor is the Moon's internal cooling.
01:24As the Moon slowly loses heat, its interior contracts.
01:28This process creates stress in the crust, forming features known as lobate scarps,
01:35which are essentially small cliffs or fault lines.
01:37Data from NASA's Lunar Reconnaissance Orbiter has identified thousands of these structures,
01:44some stretching for several kilometers.
01:47What makes them important is their age.
01:50Many of these scarps appear relatively young, which suggests the Moon is still tectonically active on a small scale.
01:58There is also direct evidence of seismic activity.
02:02Instruments left on the surface during the Apollo missions recorded moonquakes with magnitudes up to about 5.0.
02:10These are strong enough to shift surface material, especially in areas where the ground is already unstable.
02:17Recent analysis shows that some of these lunar faults may have been active within the last 50 million years,
02:24which is extremely recent in geological terms.
02:28In some regions, boulders up to several meters in size have been observed at the base of cliffs,
02:34likely dislodged by seismic activity.
02:37Computer models suggest that even a moderate moonquake could trigger cascading rock falls across unstable slopes,
02:44especially near the lunar poles where future missions are planned.
02:49This means that what looks like a small surface crack in satellite images
02:53could actually be part of a much larger and ongoing structural shift.
02:58In several locations, high-resolution images show slopes that appear to have partially collapsed.
03:05Loose material has moved downhill, leaving behind fresh-looking surfaces that stand out from older terrain.
03:11In some cases, this creates the visual impression that a chunk of the moon has broken off.
03:18In reality, these are most likely landslides or regolith movements triggered by moonquakes, temperature stress, or both.
03:27Micrometeorites add another layer to the process.
03:31The moon has no atmosphere, so even tiny particles strike the surface at high speeds.
03:36Over time, these constant impacts disturb the upper layer of dust and rock,
03:42making it easier for material to shift when other forces act on it.
03:46All of these factors combined make the lunar surface more dynamic than it appears from Earth.
03:52For scientists, this is not just an interesting detail. It has practical implications.
03:58Missions like Artemis are focused on long-term exploration, including future landings and potential infrastructure on the moon.
04:08Understanding which areas are stable and which are prone to change is critical.
04:13Regions with active fault lines or loose surface material could present risks for landing spacecraft or building equipment.
04:21That is why updated mapping and continuous observation are so important.
04:26At the same time, these changes provide valuable scientific insight.
04:31They show that the moon is not completely inactive.
04:35It is still evolving, slowly reshaping its surface through small but continuous processes.
04:41The idea that a massive piece of the moon suddenly broke off is not supported by current evidence.
04:48But smaller scale changes are happening, and they are measurable.
04:53And in some cases, they can look dramatic enough to raise new questions.
04:58Because when we look at the moon with higher precision than ever before, we are starting to see something unexpected.
05:04A world that seemed frozen in time is still changing.
05:12There's something happening inside the moon, something that nobody expected.
05:17Not a dramatic shift you'd see on the outside, but deep down, where things seem frozen in time,
05:23scientists have uncovered a hidden layer of what you could only call moon goo.
05:29Remember those school lessons about the crust, mantle, and core?
05:32Much like the Earth, the moon is made up of layers – a crust, mantle, and core.
05:38However, the moon's core is much smaller compared to ours.
05:42Earth's core is huge – it makes up about a third of our entire planet's mass.
05:47The moon's core makes up only about one to two percent of its mass,
05:51and its diameter is about one-fifth the diameter of the moon itself.
05:55It's surrounded by a hard, rocky mantle.
05:58But it turns out that between these two layers – that mysterious goo layer – and it's way more important
06:05than you might think.
06:06The layer is soft and partially molten, ebbing and flowing like the tides in our oceans.
06:12It rises and falls, stretching and shifting as if it were alive.
06:16Its movement isn't chaotic, but subtle and regular.
06:20We always knew that the moon influences our seas and oceans, causing tides with its gravity.
06:26But it turns out that we influence it back – the goo ocean reacts to the gravitational dance between Earth
06:34and the Sun.
06:35Also, the molten layer could be made of ilmenite – a very intriguing material.
06:40Ilmenite is rich in titanium – a strong and lightweight metal that we really love over here on Earth.
06:46Titanium is used in everything – from airplane parts and spacecraft to medical devices.
06:52Even in everyday items like bikes and laptops – all because it's incredibly strong and very resistant to corrosion and
06:59heat.
07:00So, if the moon might have a molten layer rich in ilmenite, that would be awesome.
07:05Astronomers are already planning for lunar bases.
07:08And if we had a material to build structures, spacecraft, or even tools for astronauts right there, that would be
07:15a game-changer.
07:17Otherwise, we'd need to transport materials from Earth, which is extremely costly.
07:22This is our first tangible sign that the moon is not just a cold, boring rock.
07:26Instead, it's dynamic, living, and breathing – with moving forces beneath the surface.
07:33NASA used new special tools to discover this – the Gravity Recovery and Interior Laboratory and the Lunar Reconnaissance Orbiter.
07:42These are both space missions designed to study the moon.
07:45But they don't just look at the surface like a telescope.
07:48Instead, they help measure things we can't see with our eyes – like the moon's gravity and how it changes
07:54over time.
07:55GRAIL sent two small spacecraft around the moon named Ebb and Flow.
08:01Clever!
08:02The idea was for these spacecraft to fly close to each other and measure tiny differences in the moon's gravity
08:08as they go.
08:09It's like they were feeling the moon's invisible pull in different places.
08:13If the moon's gravity was stronger in one spot, the spacecraft moved closer together.
08:18And if it was weaker, they moved farther apart.
08:21This helps scientists understand what's going on inside the moon, even if they can't actually go there.
08:27And the spacecraft intentionally crashed into the moon in December 2012 to end the mission.
08:33The Lunar Reconnaissance Orbiter is a bit different.
08:36It takes super-detailed pictures of the moon and collects other important information about its surface.
08:42By combining the information from both GRAIL and LRO, we were able to find this goo layer.
08:49But this discovery actually challenges everything we thought we knew about lunar geology.
08:54How did this molten layer get there?
08:56How long has it existed?
08:58And, perhaps more fascinating, how it stayed warm for millions of years?
09:03That's a million-dollar question.
09:05The moon's core generates heat, just like ours.
09:08But it's not as easy as saying, oh, the core's heat probably keeps it warm and molten.
09:14Well, first, the moon's core is much smaller and less active than Earth's.
09:18Meaning, it produces significantly less heat.
09:21Plus, the moon is much cooler than Earth in general.
09:23With temperature dropping to minus 200 degrees Fahrenheit on the surface,
09:28how could this inner layer still stay in this flowing state?
09:31That's still a mystery.
09:32In any case, this goo could actually explain a lot of stuff about the moon.
09:37For example, astronomers were exploring moonquakes and how they happened.
09:42Now they think that it might be this semi-molten layer shifting and moving beneath the surface.
09:48Now, beyond the moon itself, it also tells us more about other celestial bodies.
09:52If the moon, something we considered basically a huge static rock, has such a dramatic life,
09:59what about other planets, moons, or asteroids?
10:02Could they also hide similar hidden movements beneath their surfaces?
10:06We can even understand our own planet better.
10:09Learn more about how tides and similar stuff works.
10:12There are so many great discoveries we've been making on the moon.
10:16Recently, we found some awesome stuff beneath the surface.
10:20Massive caves hidden for millions of years.
10:23For over 50 years, scientists have suspected that the moon's surface is full of underground tunnels and caves.
10:30These are known as lava tubes because they were formed by lava. Duh!
10:35Millions of years ago, the moon was pretty unstable.
10:38It underwent some volcanic activity, causing eruptions.
10:42When a volcano erupts, lava can flow across the surface.
10:45As the outer layer of the lava cools and hardens, it forms a solid roof of dark material.
10:52It's actually what these famous dark spots on the moon are.
10:55These are dark, hardened remains of ancient lava.
10:58But the hot, molten lava continues to flow through the center.
11:02Once the eruption ends and the lava drains away, what's left behind is an empty, hollow tunnel.
11:08Hence, a lava tube.
11:10On Earth, we have lava tubes in places like Hawaii or Iceland,
11:14where volcanic activity has created similar underground tunnels.
11:18The same thing happened on the moon billions of years ago.
11:21Although, they're much crazier compared to ours.
11:24In fact, lunar lava tubes are now thought to be some of the largest and longest in the entire solar
11:30system.
11:31One such cave was discovered beneath the famous Mare Tranquillitus,
11:35the place where Apollo 11 first landed.
11:37And it's at least 340 feet deep.
11:40Now, all these lava systems have remained hidden just beneath the surface, untouched for millions of years.
11:46Only now, they've finally managed to prove their existence.
11:50Scientists from the University of Trenta in Italy found them using special radar technology and advanced computer methods.
11:58These techniques let you see underground by sending radar waves.
12:02The waves bounce back and give clues about what's hidden underneath.
12:06By analyzing the way these waves reflected back, the researchers could detect the shape and size of the hidden caves.
12:14Now, the best thing about this discovery is that we could build all our bases there.
12:19These caves protect from radiation, harsh winds, and meteoroids.
12:23NASA even found evidence that some of these caves stay at a steady 63 degrees Fahrenheit.
12:30That's some crazy coziness for the moon.
12:32And on top of that, there could even be some water there.
12:35So, humans could take shelter inside these natural tunnels and build entire colonies on the moon.
12:42And I know what you're thinking.
12:44Could unexpected lunar monsters hide deep in those caves?
12:48Well, sure.
12:49There's a huge potential for exploring these caves and finding some awesome stuff.
12:53But even if we manage to find a miracle, like small life or microbial organisms,
12:59there's a 99% chance that there won't be actual animals or monsters.
13:04It would just be impossible for them to develop in such conditions.
13:08But it would make a great horror movie.
13:11Researchers want to send robots or drones to explore the tunnels first,
13:15and then see if they're safe enough for humans.
13:18And it's not just the US getting in on the action.
13:21China is also investigating the possibility of using these moon caves as a future base,
13:27showing that the race to explore and settle the moon is eating up.
13:33You might think high-tech telescopes let us see every inch of the moon, but that's not true.
13:39At our satellite's south pole lie giant craters untouched by sunlight for eons,
13:44stuck in pitch black, colder than Pluto, and almost impossible to explore.
13:50However, maybe we have to if we want to explore space.
13:54Because the darkness hides some must-have resources that will make life and long-distance travel in space possible.
14:02Yes, we're talking about water locked up as tiny crystals in the lunar soil.
14:08Now, water in space is always good news.
14:11You've probably heard that scientists are also obsessed with finding it on Mars.
14:16If the red planet has any type of water below its surface,
14:19it raises the exciting possibility that life might have existed there.
14:24Even microbes would be the biggest discovery in human history.
14:27That's why rovers are poking around Martian craters and drilling into the soil like some very dedicated space gardeners.
14:36But as incredible as water on Mars would be, water on the moon might be even more valuable to us
14:42in the short term.
14:44The reasons are simple. The distance and the gravity of the moon.
14:47We can reach our satellite in three days. That's almost nothing.
14:52It takes at least seven days to reach New York from London via a cruise ship.
14:56But more important than the length of the trip is the possibility of using the moon as a pit stop.
15:03Stop, refuel, and relaunch so we can resume exploration.
15:08The gravity on the moon is only one-sixth as strong as Earth's.
15:13That's not just useful for endlessly entertaining yourself by jumping around.
15:17This difference means that launching rockets from our satellite is much easier compared to launching them from Earth,
15:24which requires a tremendous amount of fuel just to break free from the atmosphere.
15:28For example, the Saturn V rocket, which took astronauts to the moon during the Apollo missions,
15:34was made up of more than 90% fuel just to get off the ground.
15:39On the moon, however, it's much easier to launch a rocket.
15:43That means that we could carry heavier loads with less fuel.
15:47It's like being able to take a bigger suitcase on your trip.
15:50If we can find and use ice on the moon to create rocket fuel,
15:54it would turn our satellite into a practical and affordable stop for exploring the solar system.
16:00Not to mention that by applying some basic chemistry,
16:04we could extract oxygen from water and use it for breathing or rocket engines.
16:09Also, astronauts would need water to drink and grow crops on the lunar base.
16:14So, what do we know about the latest discoveries?
16:18For a long time, scientists thought the moon was completely dry.
16:21But in 2009, NASA basically crashed a rocket into a crater.
16:27It caused an explosion of ice and vapor, like fireworks,
16:31and finally confirmed that the moon had some kind of water.
16:36But how much?
16:37Well, enough to matter.
16:39The data suggests there could be hundreds of millions of tons of water ice
16:44locked up in the moon's polar regions.
16:46Some estimates roughly say 1.3 trillion pounds.
16:50That's about the same weight as 460 million cars.
16:54Not exactly lakes, but still a lot.
16:57And there still could be more.
17:00This water could also contribute to uncovering cool scientific secrets.
17:05The ice is ancient, which makes it like a time capsule from the early days of the solar system.
17:11Studying those frozen molecules might tell us not only how water got to the moon,
17:16but also how it appeared on Earth.
17:20Anyway, what's all that water doing on the moon?
17:23How did it get there?
17:25Scientists assume that some of it probably hitched a ride on comets and asteroids billions of years ago.
17:31Many of those space rocks carried ice, and some of that water ended up in the polar regions.
17:37Another source could be the way solar wind interacts with the lunar surface.
17:41In any case, however this ice appeared on the moon, the real trick is where it ended up.
17:47Inside its polar craters.
17:48And while we can find the ice not only in the craters at the South Pole,
17:53that's where the largest, most stable reserves are believed to be.
17:57Some of those craters are enormous.
18:00One of the most famous is called the Shackleton Crater,
18:03and it's over 13 miles wide and more than 2 miles deep.
18:07That's almost twice as deep as the Grand Canyon.
18:11The moon barely tilts on its axis, only about one degree,
18:15so the sun never peaks over the rims of those deep polar pits.
18:19The temperatures dip to around negative 400 degrees Fahrenheit there.
18:24Any water or chemicals trapped in that frozen dirt just stay there,
18:28locked away like in a freezer.
18:31Something really cool is that at the South Pole,
18:34you have parts that are stuck in the perpetual darkness,
18:37but some nearby mountain ridges get almost non-stop sunlight.
18:42Scientists call them the peaks of eternal light.
18:45They are perfect for setting up solar panels,
18:48while still being close enough to access the icy treasures hidden below.
18:53The poles of the moon are the only places in our solar system we know of
18:57where perpetual day and night exist side by side.
19:01But the eternal night isn't just fascinating, it's dangerous.
19:06The terrain out there is absolutely unforgiving.
19:10We can't even simulate something like that on Earth.
19:12We don't even know what it looks like from the inside.
19:16It's worse than exploring the northernmost part of Antarctica
19:19while wearing a blindfold.
19:21So now that we know this, is that potential water even obtainable?
19:25That question is probably worth several trillions of dollars.
19:30Yes, there's water over there,
19:31but getting to it won't be like scooping ice cream from a bowl.
19:34What we're really talking about are microscopic ice crystals mixed into lunar dust.
19:40To make use of it, machines would need to dig and heat up the soil,
19:45then capture the vapor before it escapes back into space.
19:49And then there's freezing.
19:51Even assuming a human or rover could safely reach the bottom of a crater,
19:56it'd be almost impossible to navigate.
19:59Batteries and equipment probably wouldn't last,
20:01and it's impossible to use solar panels or electronics down there.
20:05They'd freeze in minutes.
20:07However, NASA's Lunar Reconnaissance Orbiter uses all kinds of radars and sensors
20:12to sniff out what the crater looks like inside.
20:16And now there's an even sharper tool.
20:18Shadow Cam.
20:20A camera so sensitive,
20:21it can capture details in light a hundred times dimmer than what our eyes can see.
20:27Basically, the ultimate night vision device.
20:30With it, we can finally map those pits without even setting foot there.
20:35That's why engineers are thinking up all sorts of clever solutions.
20:40Some concepts involve nuclear-powered rovers with headlights strong enough to carve through the dark.
20:46Others want robots that repel down crater walls or hop across the floor like pogo sticks.
20:51There are even ideas for drills that could melt frozen soil
20:55and trap water vapor like condensation on a cold soda can.
20:59The silver lining is that this water isn't going anywhere.
21:03Until we improve our technology, the supply will wait for us.
21:07That being said, space agencies are already making advancements.
21:12In fact, more than half a dozen new missions are lined up over the next few years.
21:18NASA's Artemis program is getting ready to send astronauts back around the moon and then down to the South Pole.
21:26China's Chang'e 7 is planning to check out those dark craters.
21:31And private companies like Firefly and Blue Origin are gearing up to deliver equipment and experiments.
21:38Now, here's a bonus lesser-known fun fact.
21:41The moon smells!
21:43When Apollo astronauts brought lunar dust into their landers,
21:47it mixed with the oxygen inside and ended up smelling pretty strong.
21:51They said it was like burnt gunpowder or fireworks.
21:55Lunar dust has nothing to do with gunpowder, but its particles are highly reactive.
22:00After sitting in space for billions of years, they reacted instantly with oxygen in the cabin, creating that smoky odor.
22:08Future explorers are definitely going to notice that smell, too, since lunar dust tends to stick to everything.
22:15Let's hope that, aside from everything else, scientists will work out air fresheners for the moon base.
22:22There's a huge hole on Mars, more than 300 feet wide, and it seems that NASA agrees that it could
22:28be an opening into an underground world.
22:30Could a mysterious space civilization be hiding in there?
22:34Well, experts from NASA think that the hole might lead to a lower layer under the surface of the red
22:40planet.
22:40You can think of it like a trap door that opens into a basement.
22:45Scientists care a lot about holes like this because they might connect to big underground caves.
22:50These caves would be hidden from the surface and could be safer places for life to exist.
22:56You see, Mars' surface is a rough place.
22:59It's freezing cold, extremely dry, and constantly hit by radiation.
23:05Meanwhile, underground spaces are different.
23:07They're like natural shelters, protecting anything inside.
23:11That's what makes them some of the best places to look for signs of life on Mars.
23:17Interestingly, NASA is usually very careful when talking about life on other planets.
23:22Until now, most researchers have been focusing on tiny life forms like microbes,
23:27which might be hiding in frozen oceans on nearby planets and moons.
23:32But now, scientists really think this hole could lead to huge underground caves.
23:37If that's true, besides looking for signs of life, this spot could become a target for future astronauts,
23:45since the caves could turn into great shelters and even a Martian base.
23:50The photo with the hole isn't new.
23:53It was taken in 2017 by the Mars Reconnaissance Orbiter.
23:56In the image, we can see many holes scattered across the ground.
24:00The area basically looks like Swiss cheese.
24:04Most of the holes have dark, dusty ground under a thin layer of light-colored frozen carbon dioxide,
24:10a.k.a. dry ice.
24:12But one hole stands out from the rest.
24:14It's perfectly round, sits in the upper part of the image, and is about 328 feet wide.
24:21That's a massive opening.
24:22The hole also has a perfectly round crater around it.
24:26It's like something punched through the surface and left a ring behind.
24:30Scientists think it may have been caused by a meteor impact.
24:34Scientists believe Mars was much more like Earth billions of years ago, with better conditions for life.
24:40But today, the best chance of finding signs of life is underground.
24:44Mars no longer has a strong magnetic field or a thick atmosphere, so its surface is constantly blasted by harmful
24:51radiation from space.
24:53Underground caves or lava tubes act like natural bunkers, shielding anything inside from that radiation.
25:00This makes them the most promising places to search for life.
25:03Because of that protection, astronauts might one day find signs of past life there, or even fossils.
25:10To hunt for these hidden spaces, NASA brought in experts on underground structures and seismic activity from the U.S.
25:17Geological Survey.
25:18In 2019, they released a detailed map showing more than 1,000 possible cave entrances scattered all over Mars.
25:27There's a catch, though.
25:28All of this data comes from spacecraft flying about 250 miles above the Martian surface.
25:34From that height, scientists can spot holes, but they can't see how deep they go or what's underneath.
25:41Some may be true caves, while others could just be shallow dents in the rock.
25:47Other missions, including the European Space Agency's Mars Express, have also found signs of ancient lava tubes beneath Mars' long
25:55extinct volcanoes.
25:56But what makes this newly released image stand out is that it clearly shows at least one hole that appears
26:03to lead into an unknown underground layer.
26:06And if current plans come true, the earliest human astronauts could see this massive opening with their own eyes in
26:13the 2030s.
26:14And maybe they'll also be able to examine another Martian mystery.
26:18For more than 50 years, scientists have been puzzled by about 2 million dark streaks spread across the surface of
26:25Mars.
26:26These black marks look like long stains or shadows running downhill.
26:30It's almost like someone spilled ink on the planet.
26:33They were first spotted in the 1970s, and for decades, no one could explain what caused them.
26:40These marks are called slope streaks.
26:43They appear on steep slopes, crater walls, and ridges all over Mars.
26:47From far away, they look flat and dark.
26:50At first, scientists thought the streaks were caused by melting ice.
26:54This could create muddy landslides similar to wet dirt sliding down a hill on Earth.
27:00Even today, researchers still believe the streaks come from landslides, but not the kind involving water.
27:06New research using data from NASA's Mars Reconnaissance Orbiter shows that most of these streaks are caused by dry landslides.
27:14Instead of mud or water, it's loose dust suddenly slipping downhill, more like dry sand pouring off a pile when
27:21it gets disturbed.
27:23This explains how the streaks can form in Mars' cold, dry environment.
27:27One famous example is on Apollinaris Mons.
27:31It's an extinct volcano south of Mars' equator.
27:34On one side of a ridge, hundreds of streaks run side by side, which makes the surface look like a
27:40barcode.
27:41These streaks appeared sometime between 2013 and 2017.
27:46Scientists figured out a bit later that a nearby meteoroid impact could have triggered them.
27:51The impact didn't hit the ridge directly, but the shock shook the ground, and it was enough to send dust
27:57downhill.
27:58Now, because some streaks appeared after impacts, many scientists thought that meteoroids, or Marsquakes, were responsible for creating most slope
28:07streaks.
28:08But a new study shows that this idea is kinda wrong.
28:11The study in question looked at about 2.1 million slope streaks.
28:15They were photographed by NASA's Mars Reconnaissance Orbiter over a long period, from 2006 to 2024.
28:23Scientists have estimated that Mars has around 1.6 million slope streaks in total.
28:28But some streaks have been counted more than once because they appear in different image sets.
28:34So, after analyzing all this data, researchers have concluded that almost all new streaks form because of wind and dust,
28:41not impacts or quakes.
28:43Look, seasons change on Mars, and winds slowly move dust and sand.
28:48When that loose material suddenly slips downhill, it leaves behind a dark streak.
28:53It's like brushing dust off a surface and revealing a darker layer underneath.
28:58Meteoroid impacts and Marsquakes do create some streaks too, but only in very specific spots.
29:05Overall, they play a very small role.
29:07Less than 0.1% of new slope streaks are caused by impacts and Marsquakes.
29:14The analysis has also shown that slope streaks are not spread evenly across Mars.
29:19They're grouped into five main regions.
29:24In each of these areas, new streaks usually form during times of the year when winds are strongest.
29:30There's a key tipping point called the dust movement threshold.
29:34Once winds get strong enough to lift and move dust, the loose material on slopes becomes unstable.
29:41When that happens, dust can suddenly slide downhill, creating a dark streak.
29:46This is similar to how strong winds on Mars can kick up dust and form spinning columns called dust devils.
29:53They're like small tornadoes moving across the planet's flat plains.
29:57One reason this mystery took so long to solve is that these streaks form when scientists can't easily see them
30:04happen.
30:04The conditions that create new streaks usually occur around sunrise and sunset.
30:10And because this phenomenon happens in low light, no spacecraft has directly watched a streak form in real time.
30:17The study also calculated how often new streaks appear.
30:21On average, about 0.5 new streaks form each year for every existing streak.
30:27And since Mars has around 1.6 million slope streaks, that's roughly 80,000 new streaks forming every year.
30:33Most streaks seem to stick around for several decades before they slowly fade away.
30:39However, scientists don't yet have enough long-term data to be completely sure.
30:44Another cool discovery, even though slope streaks cover less than 0.1% of Mars' surface, they may be one
30:51of the biggest sources of dust in the Martian atmosphere.
30:54In other words, these small-looking features may play a much larger role than we expected.
30:59That's why understanding how slope streaks move dust around Mars is important.
31:04Mars' dust affects weather, visibility, and even how much sunlight reaches the ground.
31:09That matters a lot for future human colonies, which would need stable conditions to survive and operate safely.
