It's time to explore the ocean floor.

We have living quarters in space, but not on the ocean floor.

For 25 years, humanity has maintained a continuous presence on the International Space Station—a structure orbiting some 400 km above Earth—yet the environment covering more than 70% of our planet's surface remains far less explored. Now, a British company aims to change that reality; it has just deployed a new marine habitat on the seabed that could mark the beginning of a new era for ocean research.

Despite enormous advances in diving technology, scientists still face a fundamental limitation: every operation requires long periods for descent, ascent, and decompression, meaning a significant portion of time is consumed solely by travel. This reduces the time available for research and makes long-term studies extremely expensive and complex.

It was precisely to overcome this obstacle that the company Deep developed the Vanguard.

Installed at a depth of approximately 17 meters near the Florida Keys, this habitat represents the first human-occupied open-ocean habitat built, tested, and deployed in the United States. Measuring just over 10 meters in length, it was designed to house up to four aquanauts during missions lasting five days or more, serving as a permanent base for seafloor operations. The major advantage of this concept is that researchers do not have to start every dive from the surface; by living in a pressurized environment, they can make multiple daily excursions to explore reefs, test equipment, and monitor ecosystems without repeating the entire decompression process between activities.

This significantly increases productive research time and allows for the continuous observation of natural phenomena—something extremely difficult to achieve with conventional techniques—yet the Vanguard is merely the first step. It serves as a testing platform for an even more ambitious project called Sentinel, which proposes the development of modular habitats capable of sustaining teams on the ocean floor for nearly a month, thereby creating permanent infrastructure for scientific research, new technology development, and even astronaut training.

And this makes perfect sense, because living in an isolated, confined environment that is entirely dependent on life-support systems presents challenges very similar to those faced in future space missions.
