What is the Exobiology Extant Life Surveyor (EELS)?

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).
