Is there such a thing as RRGI(Road Rage God Insurance)? . - Brad Guth Thanks for the repost. It helps keeping this topic on top of the Usenet stack. BTW, I could always use a few of those gold stars for my other topic. Secret Pixels of Venus / by Brad Guth - Is God ****ed, or what? Apophis 99942 gives Earth another kiss of death. We've actually got all the time in the world, because it's technically possible to nudge this item, just enough that unless it brakes up due to gravity/tidal forces, we should be capable of causing enough trajectory drift or skew. Much like spysats in LEO, it's best keeping these pesky items as a whole rather than of many parts. Is the 2029 NEO encounter of #99942 Apophis and that of Earth taking a hit of at least 12e6 tonnes, unless safely passing us at 35,406 km (that being less than a tenth the distance to our moon) close enough? http://en.wikipedia.org/wiki/99942_Apophis size: 270 x 415 meters mass: 26 ~ 46 million tonnes SCENARIOS FOR DEALING WITH APOPHIS http://www.aero.org/conferences/plan...nery-Brief.pdf How about pondering us poor folks surviving a lithobraking encounter (most likely involving ocean vaporizing displacements) of 12+ km/s? (our NASA has Apophis encountering Earth as of 2036 at merely 12.6 km/ s and of only 21e6 tonnes) Is there such a thing as RRGI(Road Rage God Insurance)? David A. Smith: Yes, it is called a "viable, funded, space program". If I were the least bit in charge, that alternative of insuring a "viable, funded, space program" would sound perfectly good to me, especially considering the Godly potential of such horrific collateral damage and carnage of the mostly innocent, as delivered by such a whopping but glancing sucker-punch (meaning from behind), and only made worse yet if we did nothing much to save ourselves. There's roughly 21 years worth of this trajectory getting shifted or altered by factors of gravity and minor encounters along the orbital path, so there's going to be revisions in the +/- time of arrival, as for that timing and NEO distance from us as we hopefully escape the global trauma from yet another cosmic happenstance that'll forever modify life on Earth. However, 21 years simply isn't long enough for getting hardly 10% of humanity safely relocated to higher ground, much less accommodated as deep enough within Earth. For most of humanity, a direct ocean hit of that magnitude isn't exactly going to be all that survivable, even if you're situated on the opposite side. The antipodes and super-mega waves of hot ocean tsunamis haven't been estimated, perhaps because it's all too doom and gloom or dark and scary. Too bad we can't effectively modify its orbital trajectory in order to fully terminate Apophis, by way of having it impact our moon. At least that win-win option would likely save Earth as well as cover up any signs of our supposed Apollo mission, as buried under meters of that dark coal like moon dust. Once having impacted into our naked moon that's so coal like dark and nasty, and all of that highly electrostatic charged dust settles down, we could send our boys with all that "right stuff" with their undocumented R&D of fly-by-rocket landers back to their passive moon that used to look exactly like a xenon lamp spectrum illuminated guano island, in order to harvest those raw elements of Apophis, as well as to see whatever else that new hole of a crater into our moon as to offer. .. - Brad Guth |
