Creation Moment 8/25/2021 - Young Ganymede

Through faith we understand that the worlds were framed by the word of God... Hebrews 11:3
 
"June 7, 2021, NASA’s Juno spacecraft flew closer to Jupiter’s moon Ganymede than any spacecraft had ever before. Ganymede is the
largest moon in the Solar System—a body larger than the planet Mercury. Its frozen surface holds interest as a distant water source. Analysts still ponder three unique features of Ganymede, one of which they’re now seeing for the first time. If reactions to youthful features on other bodies out there offer any lesson, then long-age believers will end up once again wrestling with why this moon also looks young.

A NASA web post that accompanied Juno’s new image noted “long structural features possibly linked to tectonic faults.” And faults imply geologic activity, which of course requires energy. If these faults turn out to look like recently formed features, will uniformitarian thinkers craft tales to keep this moon’s geology energized over billions of years? That’s what happened with Earth’s Moon and with Pluto. 
Q: If over 4 billion years old, then shouldn’t these bodies all be geologically dead many times over?

NASA scientists have also trained the Hubble telescope onto Ganymede. A newer analysis of 1998 observations revealed water vapor in its atmosphere. Their 2021 report in the journal Nature Astronomy described a process where just enough sunlight hits the equator to vaporize surface ice. Lead author Lorenz Roth told NASA, “The water vapor that we measured now originates from ice sublimation caused by the thermal escape of water vapor from warm icy regions.”  
Q: Can ice keep getting sublimated off the moon’s surface for billions of years? 
 
And like so many unexpected discoveries of still-active magnetic fields in Solar System planets and moons, those 1998 spectra revealed electrified gas bands that “provided further evidence that Ganymede has a weak magnetic field.” But it shouldn’t have any magnetic field at all!
 
Magnetic fields decay like spinning tops. These magnetic fields can’t last billions of years, but they could last thousands of years, even without a dynamo. Since the Lord Jesus created this moon along with its decaying magnetosphere just thousands of years ago, as indicated by Scripture, this mystery disappears." CMI
