Swimming Microbots For Space Exploration

December 6, 2024

 

 

NNASA's Jet Propulsion Laboratory (JPL) is pioneering a groundbreaking mission concept called SWIM (Sensing With Independent Micro-swimmers). This innovative project envisions a swarm of mini, self-propelled robots designed to explore the subsurface oceans of icy moons like Europa. The SWIM project aims to deploy dozens of cellphone-sized robots that can autonomously navigate and search for signs of life in the watery depths of ocean worlds. These robots would be delivered to the subsurface ocean by an ice-melting cryobot, which would melt through the icy crust to reach the liquid water below.

Recently, JPL conducted pool tests to evaluate the feasibility of the SWIM concept. The prototypes, which are 3D-printed plastic models equipped with low-cost, commercially made motors and electronics, demonstrated controlled maneuvering and the ability to stay on course. The robots use propellers for movement and flaps for steering, allowing them to explore in a lawn mower type pattern.

The ultimate goal of the SWIM project is to enhance our understanding of ocean worlds and the potential for life beyond Earth. By developing robots that can operate autonomously in extreme environments, NASA is paving the way for future missions to explore the subsurface oceans of moons like Europa and other icy bodies in the solar system. Exploring the subsurface oceans of icy moons is crucial for astrobiology. These environments could harbor the conditions necessary for life, and studying them could provide valuable insights into the potential for life elsewhere in the universe. The SWIM project represents a significant step forward in our ability to explore these mysterious and distant worlds. Learn more at NASA.
