OceanGate’s submersible that went missing in June 2023 on a Titanic wreckage exploration relied on Elon Musk’s SpaceX-run Starlink satellites to provide communications during the expedition.
Starlink is a subsidiary of SpaceX, which Elon Musk runs, and OceanGate indeed said it was relying on the company for the exhibition, which included the submersible and a mothership — that is, a vessel that stays above water to navigate and communicate with land during the exhibition. It’s unknown if, or to what extent, Starlink was used by the submersible itself at any point, or whether it was only used by the mothership. That said, we do not know how much Starlink is responsible for the loss of contact with the submersible, nor the reasons behind that loss of contact.
On June 18, 2023, the submersible Titan was exploring the wreckage of the Titanic when it lost contact with the chartered research ship it was part of. Search-and-rescue operations soon were underway in the North Atlantic Ocean to bring up the five-person sub, who were facing the loss of oxygen and crushing pressure in the depths of the ocean, as of this writing.
When news broke of the failed communications, a number of news reports and posts claimed that the missing submersible was relying on Elon Musk’s Starlink satellites for its communications.

The claim is largely unproven.
OceanGate, the company that operates the submersible, tweeted right before the expedition that it was relying on Starlink: “Without any cell towers in the middle of the ocean, we are relying on @Starlink to provide the communications we require throughout this year’s 2023 Titanic Expedition.”
The wreck of the Titanic lies about 400 miles off the coast of Newfoundland. Without any cell towers in the middle of the ocean, we are relying on @Starlink to provide the communications we require throughout this year’s 2023 Titanic Expedition.

In another tweet, the company thanked Starlink for “the internet connection we need to make our Titanic dive operations a success.”

Starlink in turn quote tweeted OceanGate, saying, “Internet from space supporting Titanic dive expedition.”

Starlink, which develops satellite technology, is a subsidiary of SpaceX, a satellite and spacecraft company that Musk founded and runs. According to Starlink’s website, “SpaceX is leveraging its experience in building rockets and spacecraft to deploy the world’s most advanced broadband internet system.”
However, while Starlink and OceanGate were indeed working together, it was unknown if Starlink’s satellites and equipment had any role in the submersible’s communications failure. It was also not clear if, or to what extent, Starlink was used by the submersible itself at any point, or whether it was only used by its mothership — that is, the vessel that stayed above water to navigate and communicate with land during the exhibition.
Stefan B. Williams, a professor at the Australian Centre for Field Robotics, University of Sydney, wrote in The Conversation that the submersible’s communications were through a transponder that received sonar signals through the water:
The Titan would have had an acoustic link with its surface vessel, set up through a transponder (a device for receiving a sonar signal) on its end, and a transceiver (a device that can both transmit and receive communications) on the surface vessel.
This link allows for underwater acoustic positioning, as well as for short text messages to be sent back and forth to the surface vessel – but the amount of data that can be shared is limited and usually includes basic telemetry and status information.
We reached out to SpaceX and OceanGate to learn more details about the communications failure and what Starlink was doing to support the rescue efforts.
A spokesperson with OceanGate did not confirm or deny the company’s relationship with Starlink, saying he was only able to share the following statement:
OceanGate can confirm that CEO Stockton Rush is aboard the submersible as a member of the crew.
For some time, we have been unable to establish communications with one of our submersible exploration vehicles which is currently visiting the wreck site of the Titanic. Our entire focus is on the wellbeing of the crew and every step possible is being taken to bring the five crew members back safely. We are deeply grateful for the urgent and extensive assistance we are receiving from multiple government agencies and deep-sea companies as we seek to reestablish contact with the submersible. We pray for the safe return of the crew and passengers, and we will provide updates as they are available.
While OceanGate’s official Twitter account confirmed that the company did rely on Starlink for communications, it was unknown the extent to which Starlink was responsible for the communications failure and the nature of their satellite’s role in communications between the submersible and the mothership. We rate this claim as “Unproven” and will update this post once we get more information.
