Shulou(Shulou.com)11/24 Report--

Original title: "manipulate the submarine with a game console?" Details of the disappearance of the Titanic sightseeing submarine have been revealed: the star chain is responsible for communications and regular impact sounds have been detected. "

250000 US dollars (nearly 1.8 million yuan) a ticket to visit the wreckage of the Titanic 4000 meters under the sea.

Another billionaire adventure attracted attention, and Zhihu went straight to the top of the list.

In the past two days, their small submarine suddenly disappeared, and the oxygen in the submarine is now less than 30 hours. (the submarine can only provide 96 hours of air protection.)

At present, the relevant departments of the United States and Canada have launched the deepest deep-sea rescue operation in history.

While many netizens prayed and sighed, some people picked out the company behind it: they were treating the project with a playful attitude.

For example, the whole submarine is controlled by a game console?!

But now with the latest progress, rescuers have detected banging sounds with underwater sonar. And the impact is very regular, every 30 minutes, suspected that this may be the submarine crew's distress signal.

At $250000 a ticket for 18 days local time, the five-man submarine, named Titan, disappeared after falling for an hour and 45 minutes, and was last found at a depth of 3800 meters.

Then the relevant departments of the United States and Canada began to search, but due to the remote location, as well as weather conditions, night light and other uncertain factors, the search and rescue is very difficult.

At present, they can only search through surface and underwater sonar. And since the submarine is designed to provide only 96 hours of life support, there is not much time left for them to rescue.

Judging from the passengers exposed, they all have a big head.

Hamish Harding, a British billionaire who traveled around the north and south to the deepest part of the Mariana Trench, took part in the Blue Origin manned space mission last year.

Shahzada Dawood and son, one of the richest families in Pakistan.

And Paul-Henri Nargeolet, an expert who has participated in the archaeology and exploration of Titanic many times, and CEOStockton Rush, the company that owns the submarine.

Ocean Gate, similar to Blue Origin and SpaceX's way of reducing costs, is committed to providing the public with cheaper and easier deep-sea exploration. According to the official website, this is the Titan's third expedition (previously successful returns in 2021 and 2022, respectively).

Once a year, Ocean Gate was scheduled to record the Titanic and the extent of its decay, and conduct a scientific and technical investigation. The whole itinerary includes 10 days and 8 days at sea. Each passenger paid $250000 for the voyage.

In addition to the Titan, they also have two types of five-man submersibles: the Antipodes and the Cyclops 1, with a maximum depth of 305m and 500m, respectively, which are also used for commercial projects, scientific research and exploration.

However, their ambition is to plan to develop submarines with a maximum depth of 6000 meters and 20000 feet. They said publicly as early as 2019 that they were developing and manufacturing at the beginning of 2020.

But now, with the occurrence of emergencies, people have to question the engineering and technical capabilities of this company.

Using Logitech game handles to manipulate netizens picked up the video of last year's interview, saying bluntly: the founder of this submarine is very careless!

In the video, the captain declares that the submarine may cause physical injury without any approval and certification, and then shows how to "piece together" the submarine with off-the-shelf components.

For example, the lights bought at the camping store and the Logitech handles for driving submarines. That handle is also the Logitech F710 wireless game console launched in 2010, which sells for about $40.

In addition, the report also pointed out that the submarine's door was bolted, so even if it could surface, passengers would not be able to escape without the help of the crew.

And there is no in-car navigation system. There is only one button in the whole cabin the size of a minivan.

The Titan's biggest innovation is that it has a real-time hull health monitoring system that can analyze the impact of pressure changes as the submersible goes deeper, according to the website.

Another detail that attracted a lot of attention was that the company revealed before the mission that the communications for the operation were provided by Musk's Starlink.

Caused many netizens to wonder, is the accident related to the star chain?

This is true of the company's partnership with Starlink, but neither side has disclosed whether the satellite Internet service is used to navigate the submarine itself.

From a technical point of view, submarine access to the Internet is still in the early stage of research, and it is not easy to do it, especially for Starlink high-frequency signals.

Rescue operations are still under way.
