In 2018 and 2019, NASA's search for life beyond the earth at home will dive under the waves to explore hydrothermal systems of underwater volcanoes.

These particular locations might look very much like that What we will find on the other ocean worlds in our solar system – prime candidates to potentially support life.

Many projects at NASA are investigating places on He de, which are comparable to extraterrestrial locations Ling together ocean and space is called SUBSEA, which is responsible for Systematic Underwater Biogeochemical Science and Exploration Analog.

Looking for clues to similar environments on other marine worlds and their potential to support life, the team will also find the best ways to carry out a remote science mission and to optimize the future investigate exploration, which could affect short-term human exploration targets such as the Moon and Mars

This synergy of marine and space research makes a lot of sense in recognizing that robotic explorers are sent to work in both areas where humans can do it. The combination of the two worlds allows the SUBSEA team, led by Darlene Lim of NASA's Ames Research Center in Silicon Valley, California, to prepare for new types of space exploration missions by now practicing on Earth under realistic conditions.

Simulation of a Space Mission at Sea

NASA's long-term space exploration strategy may include joint human-robot missions. One possible design involves astronauts close enough to communicate almost immediately with robots exploring a surface, such as on the moon – something called low-latency teleoperations, or LLT.

The LLT crew could instantly send orders to robots for scientific direction and exploration from an Earth-based science team, though they are separated from this team by long communication delays.

The SUBSEA project operations correspond to this mission design. Their scientific fieldwork takes place aboard the ship Nautilus equipped with Hercules and Argus remote-controlled vehicles or ROVs. These underwater robots are controlled by ship-based human operators.

These in turn receive guidance from a remote science team located in US Exploration Command Centers. Connected to Nautilus via a communication infrastructure for teleoperation, video and other dat A stream provides research teams with information from the field office.

As scientists explore seabed hydrothermal systems as part of a simulated LLT mission, the entire team can begin to understand how to best perform tasks and develop tools needed for science-driven space exploration. Their approach focuses on three main areas: scientific research, scientific operations and information technologies.

Science

SUBSEA's scientific target for 2018 is the warm springs emanating from an underwater volcano off the island of Hawaii, called Lō`ihi Seamount. It provides a good illustration of the conditions that scientists believe exist on certain moons in the outer solar system, which may have the right combination of factors to support life.

Enceladus and Europa are moons of Saturn and Jupiter, the oceans under their ice hide crust. Water that interacts with rocks on the seafloor could potentially trigger chemical reactions that facilitate microbial metabolism.

It is believed that Lō`ihi's specific type of volcanic activity is similar to that at these locations, and data from his warm sources could have a major impact on scientists' predictions about the conditions on these other ocean worlds.

Science Operations

How the research is actually done-from the steps in each process to the way the team members communicate-is called surgery. SUBSEA is pursuing a multidisciplinary approach to study how science can best be achieved within the simulated space mission.

Through trials such as SUBSEA, which mimic how real extraterrestrial exploration and science could happen, the team evaluates and builds NASA's knowledge and experience in operations to support successful science-driven LLT missions.

IT

Conducting scientific research under teleoperation conditions requires software that is tailored to different space research contexts with their own unique requirements. SUBSEA will use prototype IT to evaluate which software features are required for missions with long communication delays, and improve those tools based on their ability to support LLT operations.

Impact on Ocean World Science and Mission Design

Ultimately, SUBSEA's research results will help mission design teams to develop methods that are efficient and productive in low-latency telerobotic operations in space environments such as Mars.

With its scientific results, SUBSEA will also expand our understanding of science's potential for other ocean worlds in the solar system to harbor life. Scientists will get a better idea of ​​how a series of water-rock reactions can affect the availability of energy sources to maintain microbial metabolism and where such conditions are most likely.

Milestones:


August 2018 – SUBSEA's first field campaign focuses on the characterization of geology, the energy flowing through the system, and the microbial communities associated with the Lō`ihi Seamount in Connection stand. The telepresence architecture for expeditions aboard Nautilus is being studied as a model for designing future LLT architectures for NASA missions.

2019 – In the second deployment of SUBSEA, the project will add a Mars-like communication delay to its mission simulation. The field side of the team 2019 will complement Lō`ihi – stay tuned for the goal.

Affiliates:

The SUBSEA Research Program is a partnership between government agencies, nonprofit organizations, and academic research teams that support both the Earth and the US Space Exploration, including NASA, NOAA, the Ocean Exploration Trust, and various academic centers. The funding will be provided by the NASA PSTAR Program with significant infrastructure and in-kind contributions from the NOAA Office of Ocean Exploration and Research.
