NASA is trying to justify its budget, period. Its funny, in a sick way, watching them scramble to prop up the Standard Model of Cosmology that so many of them have their careers invested in. They keep find electricity all over space and act like its not there or try and hide it by using outdated terminology like 'solar wind' or 'magnetic ropes' when they should be saying 'Birkeland Currents'. Every time I hear about comets being 'icy balls of dust' I want to laugh and point to NASA's own Deep Impact mission to Tempel 1 that showed a massively energetic burst before and after the copper projectile struck the surface of the comet, completely falsifying the 'dirty snowball' theory.
NASA is part of the machinery propping up the decaying standard model. They are no different than the Catholic bishops who excommunicated Galileo for 'heresy' by following the Copernican heliocentric model.
It gets even worse; some skeptics doubt what's taking place is what's really happening; I've tried to locate the article that details the skeptics claims, but it appears the article has been pulled or is buried; I'll see if I can dig it back up later today.
Either way, phosphorous was still required for the bacteria to thrive....so I don't see it being that particularly amazing.
