The Titan: The voyage to see the Titanic wreckage is eight days long, costs $250,000 and is open to passengers age 17 and older. The Titan is 22 feet long, weighs 23,000 pounds and “has about as much room as a minivan,” according to CBS correspondent David Pogue. Here’s what we know about the missing submersible.

The search: The daunting mission covers the ocean’s surface and the vast depths beneath. The search poses unique challenges that are further complicated by the depths involved.

The passengers: OceanGate and government officials have not released the names of the five passengers, including the pilot. But Hamish Harding, an aviation businessman, aircraft pilot and seasoned adventurer, posted on Instagram that he was joining the expedition and said retired French navy commander Paul-Henri Nargeolet was also onboard. British Pakistani businessman Shahzada Dawood, 48, and his son, Suleman, 19, were also on the expedition, their family confirmed in a statement.
