The letter was written by the girl in the text "Today, I read about Europa satellite with my father. We want to ask you questions: how does Europa Clipper capture beautiful pictures of icy satellites?" my favorite?"

A few days later, Dr. David Williams answered by hand and sent a picture with photos of the Europa Clipper and the satellite Europa and Jupiter behind.

"It is done by an artist but in fact the scene looks very much like this. Europa is one of the most interesting places in Mt Mt because it is very far and very cold (about under 300 degrees). Turning around Jupiter, like the way the Moon orbits the Earth, Jupiter's gravity has caused Europa to keep its orbit and spin around it, " Dr. David wrote.

"The Europa Clipper is still on the mission to explore Europa to find out what is under the ice. Hope you will continue to follow this journey and thank you for your interest."
