Interstellar travel is the hypothetical travel of spacecraft from one star system, solitary star, or planetary system to another. Interstellar travel is expected to prove much more difficult than interplanetary spaceflight due to the vast difference in the scale of the involved distances. Whereas the distance between any two planets in the Solar System is less than 55 astronomical units (AU), stars are typically separated by hundreds of thousands of AU, causing these distances to typically be expressed instead in light-years. Because of the vastness of these distances, non-generational interstellar travel based on known physics would need to occur at a high percentage of the speed of light; even so, travel times would be long, at least decades and perhaps millennia or longer.
Jacques-Yves Cousteau, was a French naval officer, oceanographer, filmmaker and author. He co-invented the first successful open-circuit self-contained underwater breathing apparatus (SCUBA), called the Aqua-Lung, which assisted him in producing some of the first underwater documentaries.
HMHSBritannic was the third and final vessel of the White Star Line's Olympic class of steamships and the second White Star ship to bear the name Britannic. She was the youngest sister of the RMS Olympic and the RMS Titanic and was intended to enter service as a transatlantic passenger liner. She was operated as a hospital ship from 1915 until her sinking near the Greek island of Kea, in the Aegean Sea, in November 1916. At the time she was the largest hospital ship in the world.
RV Calypso is a former British Royal Navy minesweeper converted into a research vessel for the oceanographic researcher Jacques Cousteau, equipped with a mobile laboratory for underwater field research. She was severely damaged in 1996 and was planned to undergo a complete refurbishment in 2009–2011 that has not been accomplished. The ship is named after the Greek mythological figure Calypso.
The P-700 Granit is a Soviet and Russian naval anti-ship cruise missile. Its GRAU designation is 3M45, its NATO reporting name SS-N-19 Shipwreck. It comes in surface-to-surface and submarine-launched variants, and can also be used against ground targets.
SS Thistlegorm was a British cargo steamship that was built in North East England in 1940 and sunk by German bomber aircraft in the Red Sea in 1941. Her wreck near Ras Muhammad is now a well-known diving site.
USS Makin Island (LHD-8), a Wasp-class amphibious assault ship, is the second ship of the United States Navy to be named for Makin Island, target of the Marine Raiders' Makin Island raid early on in the United States' involvement in World War II.
Azipod is a trademarked azimuth thruster pod design, a marine propulsion unit consisting of a fixed pitch propeller mounted on a steerable gondola ("pod") containing the electric motor driving the propeller, allowing ships to be more maneuverable. They were developed in Finland in the late 1980s jointly by Wärtsilä Marine, Strömberg and the Finnish National Board of Navigation.
Anton Flettner was a German aviation engineer and inventor. Born in Eddersheim, Flettner made important contributions to airplane, helicopter, vessel, and automobile designs.
A rotor ship is a type of ship designed to use the Magnus effect for propulsion. The ship is propelled, at least in part, by large powered vertical rotors, sometimes known as rotor sails. German engineer Anton Flettner was the first to build a ship that attempted to tap this force for propulsion, and ships using his type of rotor are sometimes known as Flettner ships.
Fabien Cousteau is an aquanaut, ocean conservationist, and documentary filmmaker. As the first grandson of Jacques Cousteau, Fabien spent his early years aboard his grandfather's ships Calypso and Alcyone, and learned how to scuba dive on his fourth birthday. From 2000 to 2002, he was Explorer-at-Large for National Geographic and collaborated on a television special aimed at changing public attitudes about sharks called "Attack of the Mystery Shark". From 2003 to 2006, he produced the documentary "Mind of a Demon" that aired on CBS. With the help of a large crew, he created a 14-foot, 1,200-pound, lifelike shark submarine called "Troy" that enabled him to immerse himself inside the shark world.
Philippe Pierre Cousteau was a French diver, sailor, pilot, photographer, author, director and cinematographer specializing in environmental issues, with a background in oceanography. He was the second son of Jacques Cousteau and Simone Melchior.
Jean-Michel Cousteau is a French oceanographic explorer, environmentalist, educator and film producer. The first son of ocean explorer Jacques Cousteau, he is the father of Fabien Cousteau and Céline Cousteau.
The turbosail or French turbovoile is a marine propulsion system using a sail-like vertical surface and a powered boundary layer control system to improve lift across a wide angle of attack. This allows the sail to power the boat in any direction simply by moving a single flap at the back of the sail, unlike conventional sails which have to be continually adjusted to react to changes in the relative wind.
Philippe-Pierre Jacques-Yves Arnault Cousteau Jr. is an American oceanographer and environmental activist, the son of Philippe Cousteau and the grandson of Jacques Cousteau. Cousteau has continued the work of his father and grandfather by educating the public about environmental and conservation issues. In 2017, he received an Emmy nomination for hosting the syndicated science series Awesome Planet.
Alexandra Marguerite Clémentine Cousteau is a filmmaker, sustainability keynote speaker and an environmental activist. Cousteau continues the work of her grandfather Jacques-Yves Cousteau and father Philippe Cousteau. Cousteau advocates the importance of conservation, restoration and sustainable management of ocean and water resources for a healthy planet and productive societies.
COMEX is a French company specializing in engineering and deep diving operations, created in November 1961 by Henri-Germain Delauze and ran by him until his death in 2012.

Mission 31 was an undersea expedition organized by Fabien Cousteau. It was originally scheduled for November 2013, but was delayed to June 2014. On June 1, Cousteau and six crew members descended to the undersea laboratory Aquarius in the Florida Keys. Halfway through the expedition, three of crew were replaced, as had been planned. After 31 days, Cousteau and the crew ascended on July 2.
Several vessels have been named Alcyone :
