A team has found that if there is life present outside Earth then it is Saturn’s moon Enceladus and Jupiter’s moon Europa. These two moons have shown the presence of water beneath the ice sheets and thus, the possibilities of life on it are also found have increased. The astronomers are definite that if there are extraterrestrial life forms on these celestial objects then they are nowhere related to the humans. Geophysicist Jay Melosh from Purdue University and his team assume that there must have been lithopanspermia, which means transferring of life from planet to another through the rocks ejected into space. Almost 100,000 simulated ejections have been observed to have taken place from Mars and these Martian particles show high possibilities of hitting Enceladus and Europa.
Another assumption is panspermia, which means life on Earth originated from microorganisms in outer space that were brought to the Blue Planet by objects like space dust, meteoroids, and asteroids. With a calculation that 1 Ton of Martian rocks strikes Earth annually, the Europa would have 0.4 Grams of Martian material and 2–4 Milligrams for Enceladus. The bottom line is that if life were to be found on these moons, it would be native and not seeded from Earth, Mars, or celestial bodies. If the particles were slighter slower in speed then there would be chances of life being seeded by the Martian particles.
Similarly, with the same goal of looking for life on bodies, NASA plans to kick start a new mission for exploring Saturn’s largest moon, Titan. The mission is predicted to be launched by July 2026 and the mission named Dragonfly will have a rotorcraft that will be exploring endless promising locations on the moon before it heads back by 2034. On the other hand, NASA also plans to send a mission to Europa by September 2026. And the goal of this mission is also to find whether the icy body can support life and be habitable for humans.
