Inaugural Mission | Dec 2026 | Jules Undersea Habitat

Advancing Aquanautics Training to Enable Human Spaceflight and Exploration

Mission Overview

MMAARS–NAUTILUS OPS Crew 001 represents the inaugural deployment of a next-generation analog aquanaut mission designed to advance human performance, scientific discovery, and technology validation in extreme environments. Scheduled for December 2026 at Jules’ Undersea Lodge, the mission operates within a high-fidelity underwater habitat to simulate isolated, confined, and extreme (I.C.E.E.) conditions analogous to long-duration spaceflight and planetary habitation.

The mission is commanded by Dr. Joseph Dituri, PhD “Dr. DeepSea“, a former U.S. Navy diver and recognized expert in hyperbaric medicine and extreme environment operations. Dr. Dituri is internationally known for his pioneering work in long-duration underwater habitation, including achieving a Guinness World Record for the longest continuous time living underwater. His experience provides critical insight into human physiological and psychological adaptation under hyperbaric conditions, informing mission safety, operational protocols, and long-duration habitation strategies.

Serving as Executive Officer and Human Factors Officer, Dame Emmy Jewell, MSc, PhDc, Co-Founder of MMAARS and AvatarMEDIC, is a commercial pilot with experience in Learjet and medevac operations, and a leader in analog astronautics training and human performance research. Her expertise spans mission operations, crew dynamics, aerospace systems, and the integration of frontier technologies within high-fidelity analog environments. She plays a central role in coordinating crew performance, safety, and multidisciplinary mission execution.

Together, the leadership team directs a multidisciplinary crew of veteran MMAARS analog astronauts, physician-scientists, aviators, engineers, and human performance specialists—reflecting the integrated expertise required for future exploration missions across ocean, air, land, and space.

MMAARS-NAUTILUS OPS Crew 001 integrates advanced research across AI-driven behavioral health systems, multi-omics profiling, digital twin pharmacokinetics, and ocean science, alongside dedicated astronaut health and wellness studies focused on sleep, circadian rhythm regulation, and recovery. These investigations examine the impact of isolated, confined, and extreme (I.C.E.E.) environments on cognitive performance, physiological resilience, and behavioral health, serving as a live testbed for validating next-generation technologies, operational protocols, and medical countermeasures that support human performance and long-duration mission readiness.

By bridging ocean exploration with spaceflight systems, the pioneering series of MMAARS–NAUTILUS OPS missions establishes a scalable, multi-fidelity mission framework for future deployments that will contribute to the advancement of Lunar, Martian explorations and settlements, and further expand the vision of future deep-sea habitations, while supporting the stewardship and preservation of Earth’s ocean ecosystems.
