NASA's distant Voyager 2 probe has sent a "heartbeat" signal to Earth after mission control mistakenly cut contact, the U.S. space agency said Tuesday Aug. 1.

Launched in 1977 to explore the outer planets and serve as a beacon of humanity to the wider universe, it is currently more than 12.3 billion miles (19.9 billion kilometers) from our planet - well beyond the solar system.

Human remains have likely been recovered from the wreckage of the submersible that imploded during an underwater voyage to view the Titanic, the U.S. Coast Guard said Wednesday.

An international group of agencies is investigating the loss of the Titan submersible, seeking to determine what caused it to implode while carrying five people to the Titanic.

Canadian authorities on Saturday began a probe into the implosion of the Titan submersible, whose disappearance near the wreckage of the Titanic with five men aboard had set off a multinational search-and-rescue operation.

Canadian authorities said Friday they would launch an investigation into the loss this week of the Titan submersible along with five people onboard during a dive to the Titanic wreck.

The Canadian-flagged Polar Prince cargo vessel towed the Titan out to sea last weekend but lost contact with it about an hour and 45 minutes after the submersible launched into the ocean depths.

The search for a missing Titanic-bound submersible has become an investigation and salvage mission that will take an indefinite amount of time, officials said, as tributes from around the world poured in for the five people killed when the vessel imploded deep in the North Atlantic.

All five people aboard a submersible missing near the wreck of the Titanic died - likely in an instant - after their vessel suffered what the US Coast Guard said Thursday was a "catastrophic implosion" in the ocean depths.

Since it sank on its maiden voyage more than a century ago, the Titanic has maintained an unshakeable grip on the public imagination.

The search for the missing submersible on an expedition to view the wreckage of the Titanic neared the critical 96-hour mark Thursday when breathable air is expected to run out, reaching a vital moment in the intense effort to save the five people aboard.

A massive search and rescue effort for a missing submersible near the wreck of the Titanic was at a critical stage late Wednesday, with just hours left before the oxygen supply for the five people on board runs out.
