Hunting down for an indication of life on the surface of Jupiter's moon Europa could ruin the search before it started, which is why the scientist will do the numerous research through underground. The scientist believes that Jupiter's moon Europa could possibly have a harbor microbial life because of its frozen world. Underneath of Europa, may found a 10-to-15 mile-thick of ice shell that is twice as much of water as the greater part of Earth's sea.

According to SPACE.COM, NASA's Hubble Space Telescope has spotted a confirmation of water-vapor plumes arises from Europa's south polar region that proposing the material from the sea may fall back onto moon's cold surface. NASA's exciting proposal which aims to put a lander on Europa in 2020's to search for compound confirmation that the moon could support life. However, the issue with a probe's capacity to gather untainted samples is that the site which will land would be polluted with material falling into the territory during the lander's descent.

Ralph Lorenz, a planetary researcher of Johns Hopkins University said that to moderate the shuttle's descent, they should terminate the thrusters and resemble hosing down to the ground with ammonia, and for him, this will the extremely inconvenient thing to do. Because ammonia contains nitrogen which is a substance that could show the presence of life. Ralph Lorenz added that everything on a person's body has nitrogen and it is a prerequisite for life.

However, The Space Reporter stated that the only solution for that issue is that, before gathering the samples Martian landers should move away far from the contaminated site. The scientist is in their way putting a case for equipping the Europa lander with instruments that can penetrate down to an uncontaminated layer of Europan crust. Britney Schmidt, who worked on NASA's Europa lander thinks this mission need to drill for at least 4 inches down to where the thrusters have not defiled the ice and space radiation.

Peter Willis of NASA's Jet Propulsion Laboratory in Pasadena, California stated that the Europa lander will not simply search for ammonia or nitrogen. Europa lander mission will probably drill into the ice with safety precautions. NASA additionally plans to utilize the sky-crane landing technique, which put Curiosity down on Mars with Europa craft.
