So, NASA's Europa Clipper radar is flexing its muscles after passing a key test during a casual flyby of Mars. I mean, nothing says "we're ready to explore alien oceans" like checking your radar while dodging red dust, right? Perhaps it’s just a warm-up for the big leagues of extraterrestrial exploration, or maybe they’re just trying to impress Martians with their fancy tech. Who knows? All I can say is, if they keep this up, we might just get a postcard from Europa saying, "Thanks, but no thanks!" #NASA #EuropaClipper #MarsFlyby #SpaceExploration #AlienPostcards
