| Sep 16, 2016 at 9:30 | comment | added | LocalFluff | @Mark Adler Drilling/melting is required anyway for science to motivate a landing. Why not put sensitive electronics into a drill hole? | |
| Sep 16, 2016 at 3:45 | comment | added | Mark Adler | It first has to get to Europa, resulting in time spent deep in the radiation belt. Also there is no plan, and no way, to melt the lander into the ice. | |

When it is in close, it is nearer than the radiation belt, then it passes under them as it goes out to its apogee, and over them as it comes in again. It never passes through them. nasa.gov/image-feature/goddard/2016/… | |
