Scientists to Explored Saturn’s icy Moon for Alien Life
Scientists to explored Saturn’s icy moon for alien life, One of the most ambitious projects in deep space, team of NASA researcher are proposing to send robots at the center of icy moons to explore subsurface ocean for presence of life.
The icy moons of gas giants Jupiter and Saturn which harbor sub-surface oceans perfect for hosting life, Jupiter moon Europa is creating a strong gravitational pull which is creating more heat on moon’s ice sheet which is enough to support sub-surface ocean.
Saturn’s icy moon Enceladus 500 km in diameter and 1.272 billion km away from Earth that serves a leading candidate for extra-terrestrial life, NASA innovative Advanced Concepts Programme (NIAC) has received is from researcher that jet Propulsion Laboratory (JPL) at Pasadene, California proposing robots to explore icy moons.
NASA Cassini probe strongly indicated Cryvolcanic plumes of Enceladus probably originate biomolecule friendly oceanic environment.
Surface to subsurface robotic system ICE will land on surface of icy moon, traverse to cryovolcano which is descend in opening, perform in-situ science and ultimately deploy underwater vehicles to explore a subsurface ocean.
ICE involves three modules, Descent Module (DM), Surface Module (SM) and autonomous underwater vehicles (AUVS). DM will carry AUVs and descend into vent through using a combination of climbing and hopping like experienced human mountain climber.
SM stays on the surface generating power and communicating with Earth. DM mostly relies on SM the power and communication link through cable to minimize size and weight.
When DM reach subsurface of ocean, it will launch AUVs explore the exotic environment which harbours life.
ICE brings three unique benefits; it enables in-situ science in a cryvolcano vent. Orbiters can perform in-situ science of plumes which is relatively large dust. Grains are hard to reach orbital altitude, grains that carry rich information about habitability of ocean surface.
Second, ICE enables the exploration of surfaces oceans by providing an access to it.
