Bientôt, la Lune ne se contentera plus de briller dans le ciel nocturne – elle disposera de la 4G ! La NASA et Nokia s'associent pour installer un réseau mobile à la surface lunaire, facilitant ainsi la communication des astronautes. Au lieu d'utiliser des radios à l'ancienne, les futurs explorateurs lunaires pourront envoyer des textos, passer des appels, et même retransmettre des données vers la Terre. Ce réseau 4G aidera à la navigation, au streaming vidéo et à contrôler les rovers lunaires en temps réel. Et qui sait ? Peut-être qu'un jour, nous pourrons faire des appels vidéo directement depuis la Lune ! L'avenir des voyages spatiaux semble plus connecté que jamais. 🚀📶 Animation créée par Sympa.

FunTranscript
00:00About a century ago, humanity envisaged the 21st century as an ever-increasing era of invention.
00:12This vision was not so far from reality, because we are now getting a little closer to the establishment of a real lunar colony.
00:20Before being able to build a new habitat on the Moon, it is imperative to find a way to maintain a sustainable connection,
00:26beyond the simple question of transport and logistics.
00:29Being able to send a message as trivial as, hey, what's new?
00:33is of paramount importance.
00:35It would be unthinkable to envision the installation on the Moon without a permanent link with the Earth.
00:40Let me reveal a scoop to you.
00:42A 4G lunar network is currently under development.
00:45The company that drives this project is none other than Bell Labs, bought by the famous Finnish company Nokia.
00:51Pivot of the 19th century paper industry, it then imposed itself in mobile telephony,
00:56creating emblematic devices long before the appearance of the first Apple iPhone.
01:01Once the network is operational, it will be embarked on a landing module,
01:06deployed and activated thanks to specialized radio equipment.
01:10This project is not limited to a simple technological demonstration, because its challenges are considerable.
01:17The lunar rover Outpost will explore in detail the ridge near the Shackleton crater,
01:23while Micronova will examine the lunar craters in search of ice.
01:29The collected data and images will first be transmitted to the landing module via this 4G LTE network,
01:36before being relayed to Earth, thus constituting an unprecedented advance.
01:42In addition, the importance of a reliable telephone connection could not be underestimated.
01:48Today, astronauts communicate exclusively by radio,
01:52but NASA aims to set up a lunar network capable of taking charge of high-resolution video transmission.
02:00Efficient communication is as vital as water and food during space missions.
02:07And thanks to this new 4G technology, video calls from the Moon could become a reality in the near future.
02:14In addition, thanks to the 4G lunar network,
02:17we will be able to monitor the adaptation of the endangered species sent to the Moon.
02:22Ah, but I forgot an essential detail.
02:25Faced with the growing extinction of many species,
02:28scientists are working to collect samples of animals, plants and other organisms,
02:33in order to preserve them in biobanks distributed around the globe.
02:37However, the terrestrial conditions are not optimal to ensure the preservation of these modern Noah's Arches.
02:44This is why the idea of constructing one or two biological safeboxes on the Moon seems so relevant.
02:49The southern lunar pole houses a region permanently submerged in shadow.
02:53What might seem like a happy coincidence actually turns out to be a major asset.
02:59Some lunar craters could offer temperatures close to minus 196 degrees,
03:04which corresponds to the conditions required for long-term cellular storage.
03:08Initially, the project envisaged implanting this biological hole in the lava tubes located under the lunar surface.
03:15But this option posed considerable risks.
03:18Such an installation would require a cooling system operating on solar energy,
03:23and any unforeseen failure could have terrible consequences and lead to irreparable loss of samples.
03:29On the other hand, by choosing a permanently shaded area,
03:33the hole would not require energy or maintenance.
03:37An ideal solution.
03:38As promising as it may seem, several challenges remain.
03:42One of the main obstacles is the omnipresent lunar dust, which is capable of infiltrating everywhere.
03:48If storage requires cooling systems,
03:51it will be essential to design a protection mechanism, which has not yet been realized.
03:56For now, this project is more theoretical than a concrete solution.
04:02I know you want to discover concrete facts, not simple concepts.
04:06Here is one that is at least surprising.
04:09The Moon is full of human waste, meticulously packed in bags.
04:16According to estimates, nearly 96 of these bags would rest there,
04:21and you would probably prefer to never open one.
04:24However, their content remains uncertain.
04:27A whole range of biological waste could be there.
04:31Thus, if one day you set foot on the Moon and come across one of these mysterious packages,
04:36it is better to restrain your curiosity and entrust it to scientists.
04:40They say they are impatient to be able to study them.
04:43Humanity does not lack astonishment, but often for bad reasons.
04:46We have not yet established colonies worthy of this name on the Moon,
04:50and yet, no less than 200 tons of debris are already piling up on the surface.
04:55To believe that it is more of a disordered teenager's room than a celestial body.
05:00Next to these unappetizing biological waste bags,
05:03we find cameras, drillers, towels, brushes, rakes, and a multitude of technical objects.
05:10Even more surprising, a falcon feather appears among these relics.
05:14I will explain why.
05:16During the last lunar launch of Apollo 15,
05:19David Scott carried out a demonstration using a falcon feather and a hammer,
05:23aiming to illustrate the theory of Galilee.
05:25In the absence of air resistance, all objects fall at the same speed.
05:30Among this heap of debris, we find a real work of art,
05:33which makes it possible to say that, if the Moon still hosts no museums,
05:37it can at least try to shelter a small exhibition.
05:40The Apollo 15 crew placed an aluminum figurine 8.05 meters high,
05:45designed by the Belgian artist Paul Van Huydenck,
05:48nicknamed the fallen astronaut.
05:51It rests on the ground next to a commemorative plaque,
05:54paying tribute to astronauts and cosmonauts who have contributed to space exploration.
06:01But the inventory of the unusual objects scattered on the Moon does not stop there.
06:05If you ever find yourself in lack of liquidity,
06:08know that a 2-dollar bill has simply been forgotten.
06:12Since 1969, the year when man traversed the Moon for the first time,
06:17a large amount of data has been collected.
06:20However, it was in 1609 that our satellite was observed through a telescope for the first time.
06:26But what about its real age?
06:29To answer this question, it is necessary to examine the origins of the Moon.
06:33In the mid-1980s, a conference organized in Hawaii
06:36brought together scientists to unravel this mystery.
06:40From their work emerged a fascinating hypothesis.
06:43The Moon would have formed from materials from the Earth.
06:47An object the size of Mars would have hit our planet,
06:50projecting an immense amount of matter into space in fusion.
06:54Over time, these debris would have accumulated to give birth to the star we know.
06:59This theory allows us to enlighten many mysteries.
07:02For example, the reduced size of the lunar iron core used to be an enigma.
07:08The answer is now obvious.
07:10The Moon formed from the outer layer of the Earth.
07:14Poor hell.
07:16As for its pale crust, the lightest minerals simply floated to the surface
07:20when the moon began to solidify in fusion.
07:23Originally, the Moon was much closer to the Earth,
07:26but it gradually moves away by about 5 cm per year.
07:30Determining precisely when it formed remains complex.
07:34The rock samples brought by the Apollo missions have allowed us to estimate their age.
07:39The oldest date back to about 4.35 billion years,
07:43some 200 million years after the birth of the solar system.
07:49That said, there is no absolute consensus on the exact date of the formation of the Moon.
07:54Some researchers estimate that these rocks indicate an age of about 4.35 billion years.
08:00However, other specialists in planetary formation suggest
08:04that most of the constitutive materials of the primitive solar system
08:07aggregated well before this period.
08:10According to them, such a late impact having given birth to the Moon seems unlikely,
08:15which suggests that our satellite could be even older.
08:19Another intriguing element, over its distance from the Earth,
08:22the Moon would have experienced intense heating episodes.
08:26Similar to those observed on Io, one of Jupiter's volcanic moons.
08:31Under the effect of the gravitational attraction of a massive star,
08:34a smaller body can be stretched and compressed, thus generating heat.
08:38This process would have contributed to heating the lunar rocks.
08:42These rocks contain radioactive elements that act as internal clocks,
08:46allowing us to evaluate their age.
08:48But if the Moon has experienced excessive heat,
08:51these clocks may have been re-initialized,
08:53only beginning to testify to the passage of time after having cooled down.
08:57In other words, these rocks dating back to 4.35 billion years
09:01may not correspond to the birth of the Moon,
09:04but to a later phase of warming due to tidal effects.
09:08Once again, everything suggests that our satellite is older than we imagined.
