NASA is developing a snake-like robot called the Exobiology Extant Life Surveyor (EELS), which it claims can improve space exploration by adapting to different terrains.
Exobiology Extant Life Surveyor (EELS)
Details
Purpose
Designed to investigate interior and confined dynamic terrain structures in search of indications of life.
Focus
It may explore ocean-world-inspired terrain, as well as Martian polar caps and plunging crevasses in Earth’s ice sheets, in addition to Enceladus.
Enceladus and EELS system
Enceladus is a tiny, ice body that the Cassini spacecraft named one of the solar system’s most scientifically fascinating destinations.
Scientific investigations
Work is being done to discover high-priority, high-impact scientific research that will demonstrate the snake-like robot’s potential.
EELS Robot Characteristics
Details
Propulsion and gripping mechanism
The actuation and propulsion mechanism of the EELS robot is powered by power and communication electronics. It employs a revolving propulsion unit that serves as rails, while the gripping mechanism and propeller unit assist it in reaching a plume vent exit.
Adaptability
The robot’s adaptability to different terrains and unique features allow it to explore previously unreachable locations.
Enceladus
Water vapour and ice particles shoot from a subterranean ocean beneath Enceladus’ icy crust, making it a potential lead for NASA’s quest for life.
