[Space Bites] 3I/ATLAS Is NOT Normal // JUICE Lost Contact // Mars' Lumpy Interior
3I/ATLAS is very different from any comet we’ve ever seen before, Mars is filled with fragments from ancient impacts, ESA loses contact with JUICE right before an important flyby, and the highest resolution image of a solar flare ever seen. And on Space Bites+, why asteroid made of the same material can have different colors.
