A world first

A model of scientific and societal universality

Just as the International Space Station was built on the promise of scientific and technological cooperation between the USA, Europe and Russia at the time, SeaOrbiter wishes to bring together, around its concept and its missions, the set of planetary communities whose ocean, directly or indirectly, conditions the future. Alike France, which heavily promotes the principle of the Ocean as « Common Good of Humanity », SeaOrbiter will welcome researchers from all over the world and allow sharing of discoveries as a fundamental principle of its action. In the same spirit, SeaOrbiter will offer its perspective to players from all countries, of all ages and of all social origins and, thanks to the means of communication and education available today, will help to build, across the planet, a community responsible and invested in the preservation of the ocean and its priceless resources.

An International Oceanic Station, SeaOrbiter, the marine research platform of the future, is the epitome of innovation, exploration and inspiration serving the Ocean, Space and Blue Society.

SeaOrbiter, thanks to its ability to promote innovation in multiple sectors as in many other technological and industrial areas, thanks to its international ambitions and thanks to its vision in terms of development and inspiration for young generations, has the vocation to become a universal symbol on the major issues that link the ocean and human societies: a « Blue Economy » accelerator to build a true « Blue Society ».

SeaOrbiter is the only manned vessel in the world allowing a 24/7 exploration on long-term missions of the open sea and the abyss. Inspired by Nature, it has been designed based on biomimicry principles, using the imitation of models, systems and elements of nature in order to create a symbiotic slow pace drifting vessel.


SeaOrbiter is a nomadic underwater home able to host 18 to 22 crew members to observe, listen to and study marine ecosystems 24/7 on long-term scientific missions lasting over 6 months. It enables its crew to live in symbiosis with marine animals in the midst of the oceans.


SeaOrbiter is a scientific platform that gives us a direct insight into the ecosystem of the open ocean, thanks to its capabilities of uninterrupted continuous observation and analysis of physiochemical parameters. The vessel is designed to evolve in a quiescent mode to better capture a great variety of physical and ecological data.


SeaOrbiter allows conducting experiments in a complex and confined extreme environment and to undertake permanent and direct exists into the aquatic realm at -12m below the surface. It deploys vehicles and devices for exploring the deep ocean down to 6000m. Due to its similarities with the life conditions found in space, SeaOrbiter provides a space simulator.


SeaOrbiter is a multimedia communication platform producing a constant flow of educational programs and information for the public. With its integrated multimedia production unit and its real-time communication capabilities, SeaOrbiter is able to share the adventures and discoveries directly with the world in real-time.

“It is from the ocean and the space that will be born the destiny of civilizations to come.”

Today. SeaOrbiter

SeaOrbiter is a synthesis of all of the vessels and mobile underwater homes that Jacques Rougerie has designed and built. The concept is characterized by innovating new technologies and the creative genius of its designer, which result in an unheard boldness of live marine environment observation.

1988. La Chalupa

In 1992, Richard Presley (USA) spent 69 days and 19 min in La Chalupa research laboratory, an underwater module built by famous undersea pioneer Ian Koblick and set at a lagoon in Key Largo, Florida. The test was carried out as part of a mission entitled Project Atlantis which had as its aim to explore the human factors of living in an undersea. On that occasion Jacques Rougerie and his friend Jean-Loup Chrétien, at that time still a NASA astronaut, came to visit along with Russian cosmonaut Vladimir Titov.

1982. Aquaspace

Launched in 1982, this trimaran allows 12-18 people to observe the underwater fauna and flora continuously from an observation deck below the waterline. Still in use around the Netherlands Antilles, Aquaspace pioneered a new concept in marine biology studies from the surface.

1979. Aquascope

This semi-submersible trimaran designed for underwater leisure observation operates on a variable buoyancy principle, which delivers exceptional underwater views through its large panoramic portholes. A series of 25 Aquascopes were built and some are still sailing today.

1977. Galathée

The first underwater house built by Jacques Rougerie was launched and immersed in 1977. The unique feature of this habitat-laboratory is that it can be moored at any depth between 9m and 60m, which gives it the capability of phased integration in the marine environment.

1961. Trieste

It’s onboard Trieste, a bathyscaphe developed by his father Auguste Piccard, that Jacques Piccard carried out, on January 23, 1960, along with capt. Don Walsh, an officer in the US Navy, a dive down to 10 916 m at the heart of the Mariana trench in the western Pacific, setting the world record for the deepest dive in history. This record, which still has not been beaten, was a decisive step in exploring our oceans and whose impact was planetary.

1956. Calypso

Jacques-Yves Cousteau introduced us to the Silent World through the prism of television, which gave him an audience and international acclaim. In this way the Merien community swelled as the Calypso pursued its adventures in all the oceans of the world.

1870. Nautilus

His novel “Twenty Thousand Leagues Under the Sea” was undoubtedly the first catalyst for a community known as the Meriens, mustered symbolically behind the Nautilus.

Jacques Rougerie

The original idea and design of SeaOrbiter are created by the world-renowned French architect Jacques Rougerie. SeaOrbiter continues the legacy of Jules Verne, Jacques Piccard and Jacques-Yves Cousteau, exceptional visionaries who have influenced Jacques Rougerie in his 35 years of research.

Jean-Loup Chrétien

The first Frenchman and the first European in space, Jean-Loup Chrétien has three space flights on his name. The long-time friend of Jacques Rougerie has been notably instrumental in getting the space agencies, particularly NASA, on board with the SeaOrbiter project, initiating the link between space and the ocean which is now at the heart of the SeaOrbiter program.

1981. Hippocampe

This underwater habitat was launched in 1981 to act as a scientific base suspended in midwater, using the same method as Galathée. Hippocampe can accommodate 2 people on saturation dives up to a depth of 12m.

1978. Aquabulle

Launched for the first time in March 1978, this underwater shelter suspended in midwater (between 0 and 60 meters) is a mini scientific observatory 2.8 meters high by 2.5 meters in diameter. The Aquabulle can accommodate 3 people for a period of several hours and acts as an underwater refuge. A series of Aquabulles were later built and some are still being used by laboratories.

1973. Underwater village

In 1973, Jacques Rougerie imagined a submerged village where men can live beneath the sea. The village was designed to accommodate aquanauts and astronauts. Its biomimetic architecture was later adapted to the study and management of sub-aquatic resources.

Jacques Piccard

Son of the famous Auguste Piccard who pioneered the stratospheric balloon, Jacques Piccard was one of the greatest explorers of the ocean abysses of the 20th century. Piccard together with Jacques Rougerie would go on to develop the idea of a drifting vessel which culminated in the birth of SeaOrbiter.

Jacques-Yves Cousteau

The father of modern diving, Jacques-Yves Cousteau was on one the three famous “Mousquemers” (musketeers of the sea). Together they popularized diving and opened up the underwater world to the wide public, Cousteau in particular taking the route to cinema and television. He was the first to install houses on the seabed, inspiring Jacques Rougerie in his creations.

Jules Verne

Jules Verne’s vision on how technology could allow people to move freely in the undersea world had a powerful influence on Jacques Rougerie, who adopted the maxim of this great writer:

Anything one man can imagine, other men are capable of realizing”

SeaOrbiter’s contribution to science will encompass a wide spectrum of scientific fields and allow scientists to better understand its links with the atmosphere and the planet’s climate. It will also provide opportunities to discover new species and new molecules that will allow enhancing new marine wealth that will tomorrow be a source of innovation and progress.


Through producing a constant flow of educational programs and information for the public, SeaOrbiter will enable a better understanding of the Ocean’s critical role within our planetary system, notably in the context of global warming and its many impacts on the Ocean, its balance, its biodiverity and its related human and socio-economic communities.


While exploring the wonders of nature that lie in the heart of the Ocean SeaOrbiter’s mission is to inform the public on the vulnerability of the oceanic ecosystems and induce action towards their preservation and a more responsible and sustainable use of the Ocean’s resources. It will thus embrace the idea of the Ocean as a common good for Humanity.
