About Exobiology Extant Life Surveyor (EELS):

What is it? It is a mobile instrument platform conceived to explore internal terrain structures, assess habitability and ultimately search for evidence of life.
It is designed to be adaptable to traverse ocean-world-inspired terrain, fluidized media, enclosed labyrinthian environments and liquids.
It is a snake-like robot that that can move through rough terrain.
Its purpose is to examine the surface of Saturn’s moon and determine whether life is present.
EELS allows for deeper exploration into areas that were once unattainable.
Features:
- It is made of multiple, identical, segments containing both the actuation and propulsion mechanisms as well as the power and communication electronics to drive them.
- EELS uses first-of-a-kind rotating propulsion units that act as tracks, gripping mechanisms and propeller units underwater, enabling the robot to access a plume vent exit and follow it to its ocean source.

Q1) How many moon does Saturn has?

Saturn has 83 moons. Sixty-three moons are confirmed and named, and another 20 moons are awaiting confirmation of discovery and official naming by the International Astronomical Union (IAU).
