Essential to Future missions by the Radiation maps of Jupiter’s Moon Europa

New ultimate radiation mapping of the Jupiter’s icy moon Europa discovers which scientists should look and they will have to search the habitability and biosignatures signs. Galileo mission of NASA gives substantial evidence of global ocean under the icy shell of Europa in the year 1990. Scientists have considered this moon one of the most significant places in our solar system to get the ingredients to support life. There is other evidence of salty water flowing around the interior of the moon that makes its way to the surface. 

By researching or studying this material from the interior, scientists improving future missions to learn more about the habitability possible of Europa’s ocean. Europa surface is bombarded by an intense and constant Jupiter radiation blast. This radiation can alter or destroy material brought up to the surface. It is making more difficult for the scientists to know if it actually presents the conditions in Europa’s ocean. 

Scientists plan for the upcoming discover of Europa, they have met with many unknowns, such as where is the intense radiation comes from? How dark are the particles go? How does radiation effects on the surface and beneath, that includes biosignatures or chemical signs, could influence the presence of life? 

In nature astronomy, a new study has published, and it represents the complete radiation mapping and modeling at Europa and provides significant pieces to the puzzle. Tom Nordheim, a research scientist at NASA's Jet Propulsion Laboratory, Pasadena, California is the lead author of this new study. 

Nordheim said that if they want to understand what’s going on at the Europa’s surface and they need to know how the links to the ocean radiation are underneath. By using the Galileo’s flybys Europa data and NASA’s electron measurements from NASA's Voyager 1 spacecraft, Nordheim and his group found firmly at the electronic blasting at the moon’s surface. They found that the radiation differs from various locations. The harsh radiation accumulated around the equator and the radiation minimizes closer to the poles. 

Chris Paranicas, a co-author from the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, said that this is the first radiation prediction at every point on Europa’s surface and it is essential information for future Europa’s mission.  

Europa Clipper’s mission group is examining orbit paths and Europa experiences the lower level radiation. Kevin Hand, the co-author of the new research and project scientist for the potential Europa Lander mission, said that, its good news that the fingerprint of radiation has not modified looking for ocean-fresh material and it.
