Imaginez flotter dans le vaste silence de l'espace quand, de nulle part, vous entendez un mystérieux bruit de thump-thump—comme un battement de cœur résonnant à travers le vide. 🚀C'est exactement ce que les astronautes ont rapporté pendant les missions, et personne ne sait vraiment d'où cela vient ! Certains pensent que ce n'est que le métal du vaisseau spatial qui se dilate et se contracte, tandis que d'autres croient que cela pourrait être quelque chose d'encore plus étrange, comme de l'énergie cosmique interagissant avec le vaisseau. La partie inquiétante ? Le son n'est pas capté par les instruments, seulement entendu par les astronautes eux-mêmes ! C'est comme si l'espace lui-même murmurait un petit secret inquiétant. Quelle que soit l'explication, une chose est sûre—l'espace n'a jamais été aussi effrayant ! 🌌🔊 Animation créée par Sympa.

FunTranscript
00:00Two astronauts are currently stuck in space.
00:05It all started when they heard a frightening pulsating noise coming from inside their spacecraft.
00:11A noise that should not even be possible in the vacuum of space.
00:15The situation became so strange that their return trip from the International Space Station was canceled.
00:22What was supposed to be a few days in space, turned into 9 months of a real nightmare.
00:29This situation is that of the astronauts of NASA Butch Wilmore and his colleague Sunita Williams.
00:35On June 5, 2024, they left Earth with a mission.
00:40Spend about 24 hours on board the Starliner spacecraft from Boeing to reach the space station.
00:46They then had to stay there for only 8 days, alongside the 7 astronauts already on board.
00:52After that, they had to return to Earth, again with the Starliner spacecraft.
00:56Nothing easier in appearance.
00:58However, as they were about to return to Earth, something strange was happening there.
01:03Wilmore began to hear a strange noise inside the Starliner capsule.
01:08It sounded like a heartbeat, with regular intervals.
01:17What is frightening is that space is supposed to be totally silent,
01:21given that there is no environment for sound to propagate.
01:24There are no atoms or molecules to transport a sound wave, so there is no sound or echo.
01:30Nobody will hear you scream.
01:32It is total silence.
01:34It was therefore impossible for these strange noises to come from outside the spacecraft.
01:40The situation became very worrying, because the noise did not stop.
01:44In addition, the astronauts could not determine where it came from.
01:48They knew it came from a loudspeaker inside the capsule.
01:52But they had no idea what caused it.
01:55They therefore decided to ask the experts at the Johnson Space Center in Houston for help.
02:01Before continuing, it is important to know that strange sounds in spaceships are not uncommon.
02:07In 1969, when the Apollo 10 mission entered lunar orbit,
02:12the astronauts said they heard a mysterious music coming from the hidden side of the Moon.
02:18It was like a whistle that lasted about an hour.
02:21It was so strange that they said no one would believe them.
02:25According to the experts, the sound could have been caused by radio interference,
02:29perhaps due to magnetic fields or the atmosphere.
02:32But, here it is, the Moon has no magnetic field,
02:35and not enough atmosphere for sounds to propagate there.
02:39The mystery remains whole.
02:42Something similar happened in 2003.
02:45Chinese astronaut Yang Liwei made his first space trip.
02:50Alone, aboard a tiny spacecraft, when he began to hear something strange,
02:55it would have been said that someone was hitting the hull of his ship.
02:58A bit like someone hitting a metal bucket with a wooden hammer.
03:03But what was even stranger,
03:05is that the sound did not seem to come from outside or inside the vehicle.
03:10Liwei could never determine what it was, even after his return to Earth.
03:16But the situation was strange enough to make him panic.
03:19And that's probably what happened to Wilmore and Williams.
03:22But in the case of NASA astronauts,
03:25it seems that an explanation has finally been found.
03:28According to the mission control center team,
03:30the sound was probably linked to a technical problem.
03:33They think it was a retroactive loop of speakers
03:37between the space station and the Starliner spacecraft.
03:40Rather satisfying, isn't it?
03:42Well, not really.
03:44Their troubles were just beginning.
03:47This sound problem obviously worried the Johnson Space Center team.
03:51But in truth, there were quite a few other technical problems on board this ship.
03:55Even before its launch,
03:57experts had noticed a small persistent helium leak.
04:01This could be a big problem,
04:03because this gas feeds the propellers that control the orientation,
04:06speed and trajectory of the shuttle.
04:09But in this case, the specialists had said that everything would be fine.
04:13The leak was not too important
04:15and did not risk compromising the success of the mission.
04:18They had therefore decided to proceed with the launch.
04:21But things got worse.
04:23Once the astronauts in space,
04:25the specialists noticed another helium leak,
04:28then another, and another.
04:30In the end, they found five leaks,
04:32which worried the mission managers a lot.
04:35They therefore urgently contacted Wilmore and Williams.
04:39The astronauts were about to fall asleep
04:41when they received the order to close two valves on the shuttle.
04:45Thus, they would be safe
04:47and would still have enough helium for their return trip.
04:50And when it seemed to them that everything was back in order,
04:53it turned out that this was not the case.
04:55The shuttle also had problems with the propeller control system.
04:59There were 28 of them, small in size,
05:01and five of them had problems at one point or another in their trip.
05:06Four of them were repaired quite quickly,
05:09but the fifth never turned on again.
05:12So, first, there were the helium leaks.
05:15Then, the propellers that did not work properly.
05:18And now, there was this strange pulsating noise
05:21coming from the inside of the ship.
05:23Problems kept accumulating.
05:25Suddenly, bringing the astronauts back to Earth
05:28had become far too risky.
05:30This is why NASA decided to cancel their return trip.
05:33In fact, they postponed their eight-day stay
05:36at the space station to nine months.
05:39They are currently planning to bring them back to Earth in March 2025,
05:43but it is difficult to confirm,
05:45because this date has already been postponed.
05:48What we know with certainty
05:51is that the two astronauts are stuck in space
05:54waiting for NASA's SpaceX Dragon shuttle to bring them back to Earth.
05:58In the meantime, they share their floating house,
06:01which is about the size of a six-room house,
06:04with this other person.
06:07Being stuck in a laboratory in orbit
06:10and not being able to go home
06:12is undoubtedly a difficult situation,
06:15but it seems that they manage things pretty well.
06:18Both had already spent two long days in orbit before.
06:22So, even if their families miss them,
06:25our two astronauts are used to it.
06:27They even declared that they were grateful
06:30to be able to spend more time in space.
06:32Before the start of their mission,
06:34NASA had also made sure that they understood all the risks involved,
06:38including the possibility that they would stay in the station longer than expected.
06:42This is why Wilmore and Williams
06:44accepted the new date of their return to Earth without any problem,
06:47and they found something to do up there.
06:49They do a whole range of scientific work.
06:52They focus in particular on the maintenance of the space station,
06:56and they test different techniques
06:58to develop off-Earth farming methods.
07:01It is very important to understand
07:03how plants grow in space
07:05and to ensure that they receive the right amount of water and nutrients.
07:09All the more so because space travel
07:11takes us further and further,
07:13far beyond the Moon.
07:15A lot of people worry about their safety and their health,
07:18but there is no need to fear anything.
07:20They are doing perfectly well.
07:22Staying on board the space station
07:24usually lasts six months or more.
07:26In addition, the place is well supplied.
07:29There is everything the crew needs,
07:31food, water, clothes, and oxygen.
07:34NASA and its partners often carry out missions
07:37with additional supplies
07:39to ensure that everyone feels safe and taken care of.
07:43If Wilmore and Williams have a bad time in the country
07:46and have a little free time,
07:48they can always send emails,
07:50call their families and friends.
07:52The Starliner spacecraft returned to Earth on September 24, 2024.
07:57But it was empty, of course,
07:59without Wilmore and Williams.
08:01It traveled in autonomous mode
08:03after disengaging from the space station.
08:05And it entered the Earth's atmosphere
08:07after six hours of travel,
08:09using parachutes to slow down
08:11before landing at the White Sands Space Harbor
08:14in New Mexico.
08:16The landing was a success,
08:18but NASA specialists would have liked
08:20it to go as planned,
08:22that is, with Williams and Wilmore on board the shuttle.
08:25Now, all we can do
08:27is hope they get home safe and sound.
