B Radar & Jupiter Great Red Spot

  1. Apr 4, 2017 #1
    Ever since the first Pioneer spacecraft sent back closeup photos of Jupiter's Great Red Spot ("GRS") back in 1978(?), I noticed the GRS looks like a wave-cloud. There is a thick lip of wave-cloud on one side of the GRS, caused by air sweeping over an enormous volcano, it then bends around on both sides as it is pushed by prevailing wind, and thins out, leaving heaps of turbulence in the coriolis-effect-driven interior.

    I know this doesnt fit current Jovian construction theories, yet the photo evidence is there. Every planet has a major volcanic feature: Earth, Moon, Venus, Mars, why not the gas giants as well? (Then the problem becomes how can rock be so light unless it is lithium-based?)

    Has anyone tried bouncing radar off the Jupiter GRS to see if a bright reflection occurs, revealing a massive volcano? Bouncing radar off shrouded Venus produced a flurry of science investigations. No one has tried bouncing radar off Jupiter simply because they expect to find nothing. Well, here is a reason to go looking. It would be historic, if a surface anomaly is found.

    I'm sorry, but there is no easy way to sugar-coat a critique, so I'm going to have to lock the thread before it goes really bad, really fast. Some short answers:

    1. No, as far as I know, no one has tried to penetrate Jupiter's atmosphere with radar. But they did send a probe 150 km down through it.

    2. No, the GRS doesn't look anything like a wave-cloud, which would be wedge shaped, not round.

    3. No, solid lithium is many, many times denser than gaseous hydrogen -- and Jupiter is way, way too light to have a significant core of anything solid.
