"A dot of light. This is what Europa has been for almost four centuries: a tiny source of light."
"The satellite had to be still geologically active, which meant that there must have been a permanent heat source inside Europa."
"A real ocean, a hundred kilometers deep and with a volume at least double that of all the terrestrial oceans put together."
"These characteristics made Europa one of the most interesting places in the search for microbial chemosynthetic life."
"The surface of Europa is ice, and underneath that ice is a liquid ocean."
"Europa, one of Jupiter's many moons, is a frozen planet containing a massive water reserve underneath its ice crust."
"The Europa Clipper Mission won't be the first mission to look at said moon, but it will be the first entirely dedicated to helping us better understand this intriguing member of our solar system family."
"As Europa goes around Jupiter, it's flexing, and sometimes it's a little closer to Jupiter, sometimes it's further away."
"This flexing is inducing heat on the interior, which is able to keep that water liquid."
