The Cryobot Mission Concept
In February 2023, a NASA-sponsored workshop brought researchers together to explore the potential of a groundbreaking cryobot mission.
NASA is supporting a unique project to create a group of small, smartphone-sized robots that can swim through thick icy water on moons in our solar system. These robots aim to detect signs of life in places like Jupiter’s moon Europa or Saturn’s moon Enceladus.
The funding is granted to Ethan Schaler, a robotics engineer at NASA Jet Propulsion Laboratory. He came up with the concept called sensing with independent micro-swimmers (SWIM).
With the new investment, the team plans to build and test 3D-printed prototypes of these bots in the next two years.
The microbots are designed to be sent inside a probe that melts ice, allowing them to explore places that are hard for humans or robots to reach.
The early designs show these microbots are around five inches long, three to five cubic inches in volume, and equipped with their own propulsion, computer, and communication systems.
They also have sensors to measure temperature, salinity, acidity, and pressure.
In the second phase of the study, the team aims to add chemical sensors to detect signs of life or biomarkers.
These bots would stay connected to the surface through a communication tether, enabling the Earth team to be in touch, although it limits the range of exploration.
The group deployment of these bots allows NASA to collect more accurate data by comparing readings between the devices, reducing risks while enhancing scientific discovery.
NASA is gearing up for the Europa Clipper mission, scheduled for launch in 2024, and the development of these cryobots is a crucial part of NASA’s long-term plan to explore ocean worlds on moons like Europa.
Various concepts are being explored under the NASA Scientific Exploration Subsurface Access Mechanism for Europa (SESAME) program.
NASA’s $600,000 Venture into Robotic Exploration of Ocean Worlds
NASA is investing $600,000 in studying the possibility of sending small swimming robots, known as independent micro-swimmers, to explore oceans beneath the icy surfaces of certain moons in our solar system.
These ocean worlds, like Europa (a moon of Jupiter) and Enceladus (a moon of Saturn), have intrigued scientists because they might harbor conditions conducive to life.
Unlike our Earth, where sunlight and atmosphere play a crucial role in sustaining life, these ocean worlds rely on heat generated by tides.
Chemical interactions between rock and ocean water in these environments could potentially support life, similar to conditions on Earth when life began.
The proposed project, called Sensing with Independent Micro-swimmers (SWIM), envisions deploying small robotic wedges after melting a hole in the icy surface.
These micro-swimmers would explore the ocean, communicating acoustically with a probe on the surface, which, in turn, would send data via cable to a lander.
While the project is still in the conceptual phase, its goal is to investigate the oceans of these distant moons, searching for signs of life or habitability.
The micro-swimmers would operate collectively, mapping changes in temperature, salinity, and possibly even cloudiness of the water. Although the project faces challenges, it represents a promising step toward understanding the potential for life beyond Earth.
Challenges and Progress: A Collaborative Effort
Researchers, supported by NASA SESAME and COLDTech programs, have dedicated years to overcoming the challenges of adapting thermal ice drilling for planetary exploration.
In February 2023, a workshop convened to discuss advancements and assess remaining hurdles, bringing together experts from diverse fields and institutions.
The cryobot mission concept represents a crucial step toward unlocking the secrets hidden beneath the icy surfaces of Europa and Enceladus, offering unprecedented opportunities for understanding extraterrestrial environments and the potential for life beyond Earth.
