Banging sounds coming at 30-minute intervals have been heard in the search for the missing Titanic-tourism submersible, according to Rolling Stone, which cited an internal email update sent by the Department of Homeland Security’s National Operations Center.

The detection of “sounds” was announced by the U.S. Coast Guard (USCG) Northeast early Wednesday (June 21), but it has not been confirmed whether they are coming from the missing vessel with five people on board. 

“Canadian P-3 aircraft detected underwater noises in the search area,” USCG Northeast tweeted. “As a result, ROV [remotely operated vehicle] operations were relocated in an attempt to explore the origin of the noises. Those ROV searches have yielded negative results but continue.”

The OceanGate Titan submersible went missing on Sunday (June 18) around 1 hour and 45 minutes into its 2-hour descent to the Titanic wreckage in the North Atlantic Ocean. As of 5 a.m. ET Wednesday morning, the submersible has less than 30 hours of oxygen remaining.  

What happened to the submersible is unclear. Possible scenarios include power loss, getting snagged on a piece of the Titanic or an implosion, potentially from a defect in the sub’s shape or build. The latter would mean that the five people on board — British explorer Hamish Harding, British-Pakistani businessman Shahzada Dawood and his son Suleman, former French navy diver Paul-Henri Nargeolet and Stockton Rush, chief executive and founder of OceanGate Expeditions, the company running the expedition — are unlikely to be alive. 

However, the discovery of sounds could mean that the passengers may still be alive, and search efforts are now focusing on the area they appear to be coming from. 

David Gallo, an American oceanographer who co-led an expedition to create a detailed map of the Titanic wreckage, told CNN the search for the submersible must now ramp up. “Time is of the essence because once you … have an area where you know that the bangs are coming from … you need to get assets there — submarines and robots — over that spot to investigate,” Gallo said.

“You can’t wait to slowly prove that there is something there. You should assume that there is something there, and move things now because time is running out.”

According to the email seen by Rolling Stone, the 30-minute bangs were detected by a Boeing P-8 Poseidon — a maritime patrol and reconnaissance aircraft that has underwater detection abilities from the air. Sonobuoys — small buoys that can perform underwater acoustic research — were then deployed. “The P8 heard banging sounds in the area every 30 minutes. Four hours later additional sonar was deployed and banging was still heard,” the email said. 

In an email to Live Science after the banging sounds were detected, Nicolai Roterman —  a deep-sea ecologist and marine biologist at the University of Portsmouth in the U.K. — said the 30-minute intervals would “certainly be consistent with the idea of a trapped crew trying to contact the outside world, while at the same time conserving energy and therefore oxygen.”

He added: “If this is the case, then it would indicate that the submersible is on the seafloor and either the system for jettisoning weight has failed, or Titan is snagged or trapped somehow.” Retrieving a stricken submersible

In a statement released before the detection of sounds was announced, Roterman said: “If the submersible is intact but unable to jettison weight or is snagged on the seafloor, the challenges for rescue become more acute, even if Titan is found. There are no submersibles that I’m aware of capable of rescuing people from a submersible at the depth of the Titanic (3,800 m) [12,500 ft]. However, it could conceivably be possible for an ROV to help un-snag the Titan, or to attach a tether of some sort.

“Whether or not retrieving a submersible from 3,800 m depth is practical is another matter, given the roughly 10-tonne [11 short tons] displacement of Titan and the kilometers of heavy cable required, a very powerful winch would be needed… I’m unaware of any submersible retrieval from such depths.”RELATED STORIES—Stunning full-scale scan of Titanic reveals complete shipwreck for the 1st time

Roterman said that if the passengers are still alive on the seafloor, it would be extremely still and — if a power failure has occurred — very cold.

“If they have no power and no auxiliary systems, they will be in darkness as well. Because the hull will be cold under such conditions, condensation from breath will start to collect on the inside of the hull, which can be unnerving,” Roterman said. “The conditions are cramped with no room for standing up straight or stretching out, which can lead to numbness and cramp in the limbs. Given the situation, a big challenge for the occupants of Titan will be to maintain composure and not to panic, so as to prolong their air supply.”

Earth’s Oldest Impact Crater Turns Out to Be Much Younger Claims New Study

Earth’s Oldest Impact Crater Turns Out to Be Much Younger Claims New Study

A location in Western Australia that used to be named as the oldest meteorite impact crater on Earth is now actually a lot younger than that, scientists announced today in Science Advances. The structure — previously dated to 3.5 billion years ago and located within Western Australia’s North Pole Dome region of the Pilbara — was believed to be older than any of Earth’s known impact craters. Today, new research published in the journal Geochemistry found that what we now call the Miralga impact structure is, in fact, much younger, at 2.7 billion years old, and considerably smaller in diameter. This recasts earlier ideas on the early Earth’s geological activity and questions previous theories regarding impact-driven crust formation or perhaps even early life.

Miralga Crater Loses Oldest Impact Title but Gains New Scientific Relevance

As per The Conversation article republished by Space.com, the teams that explored the crater could only point to one thing that was likely — it had been formed by an impact. However, they ultimately disagreed as to whether this event had been and how large it was. Younger rocks contain shatter cones, indicating Earth’s early continental geology shielded the impact to a specific 2.7 billion-400 million-year period despite earlier assertions.

They made the determination to honour the cultural revision of one site from 100 km across to a more manageable 16 km wide crater named Miralga. It’s the site – still affected by seawater – of events too recent to influence the Earth’s crust.

The Miralga basalt feature (unique to basalt) is a rare site for an instrument to practice on before heading to Mars, while advancing our understanding of impacts and early life prospects.

Isotopic dating to clarify the crucial part played by this, the oldest crater on Earth and unique in a geological sense, in planetary science and early Earth history is presently ongoing at Miralga.

Get up to $200 in first savings on Bluetti’s new Elite 30 V2 portable 288Wh LiFePO4 power station starting from $199

Back on Friday, Bluetti launched its new Apex 300 Versatile Power Station with up to $3,150 in exclusive savings that has had fans of the brand buzzing, while also eclipsing another new and more compact release. Now, with its latest Solar Generator Sale, Bluetti is cutting the cost on its Elite 30 V2 Portable Power Station to $199 shipped, with that price matching at Amazon for Prime members, bringing it down from the $299 price tag. It just hit the market at the top of the month, but as I said, its release was overshadowed by the larger and more expansive Apex 300 unit and its bundles. You can score a $100 markdown now, though, which sets the bar for future discounts, with a solar bundle option for this model that tacks on a 100W panel for $398 shipped, down from $598.

While larger solar generator setups can help through many situations, more and more people are finding convenience in owning smaller backup power solutions, especially here in NYC, with many folks having limited space to keep them. That’s where units like Bluetti’s Elite 30 V2 Portable Power Station come in, which offers a 288Wh LiFePO4 capacity to cover personal device charging with 600W of steady output that can ramp as high as 1,500W.

Bluetti’s Elite 30 V2 power station has nine different port options to cover all the bases: two AC outlets, two USB-C ports, two USB-A ports, two DC ports, and a car port. It even beats out many counterparts/competitors of the same size range with five ways to recharge its battery: via a standard outlet, utilizing up to a max 200W solar input, using both an outlet and solar panels together, connecting a generator, or using your car’s auxiliary port.

You can get the full rundown on Bluetti’s other new and more expansive release, the Apex 300 Versatile Power Station with up to $3,150 in exclusive savings across several bundle options – all starting from $1,439.
