Jupiter a planet 1200+ more massive than Venus, tremendous gravitation tug inward still produced awesome plumes... Now consider a 6-10mile or greater bolide... the atmosphere of Venus is dense, but it is a gas and therefore fluid, with these sorts of ergs the turbulence and eddys may assist ejection... i am not a mathematician, but would submit that if a 6-10 mile bollide were to impact Venus at the right angle, it could easily eject rocks from the surface into space, despite its dense atmosphere! the atmosphere is dense but not very thick! Also, do we know what the atmosphere of Venus was like in its earlier history?? Do we have an ejection time line, as some scientists apparently do with Martian samples? Venus may be dynamic today, and was probably active in the past, so what? there are regions on venus that are apparently more active than others and as i've stated when were the rocks ejected ... 3.5/4 billion years ago maybe? how many Venusian like objects should we encounter? or expect? we have only just recently found a handful of lunar specimens and look how close the Moon is respectively, and look at the numbers of impacts!! on the moon! i would "expect" to see tons on earth... we don't because most more than likely ended up in the oceans eons ago for most significant impacts ceased 3 billion years ago! we're just now finding these extra polar lunar/martian material now because more people are starting to look...in the right sort of places : the cold and dry deserts of the world... the real questions are : how do the chemistries of Venusian rocks compare with Ureilites their relative isotopic abundances and as i've stated in a privious letter primative Ar/Ne and others analysis of the Venusian atmosphere and Ureilites... oh, by the way, we've increased our supply of Ureilites recently because of luck hundreds of people searching the n. africian deserts.... this is great !! let's have their chemistries explored we need another Vensian probe, but we do have some data on vensian rocks directly from several probes... that needs closer examination Regards, Karl --- Joseph Hum --- jkarlhum_at_earthlink.net --- EarthLink: It's your Internet. ------=_NextPart_84815C5ABAF209EF376268C8 Content-Type: text/html; charset=US-ASCII <HTML><HEAD> <META content="text/html; charset=windows-1251" http-equiv=Content-Type> <META content="MSHTML 5.00.3211.1700" name=GENERATOR></HEAD> <BODY> <P> <DIV></DIV> <DIV>in reply to the privious two statements concerning Ureilite/Venus</DIV> <DIV> </DIV> <DIV>we should not prematurely conclude there is no connection </DIV> <DIV>with insufficient data and interpretation</DIV> <DIV> </DIV> <DIV> </DIV> <DIV>yes, the Venusian atmosphere is extraordinary</DIV> <DIV>if you were to expose yourself to it you would be squashed like a bug</DIV> <DIV>and then roasted to ash in it 850+ F ambient tempeture</DIV> <DIV>you also have the curiosity of Titan but,</DIV> <DIV>anyway, i'm not sure about the total obliteration/vaporization of all rock</DIV> <DIV>from Any impactor ! there are always zones of protection/buffer and this</DIV> <DIV>has recently been demostated with various martian meteorites, some zones on the edge</DIV> <DIV>do not receive as an intense shock to its mineralology as of course of vaporization or </DIV> <DIV>intermediate zones...and still have enough energy to leave Mars! </DIV> <DIV>also, if we consider comet shoemaker/levy-9, those fragments only</DIV> <DIV>avg'd 1 -2 kms in size and shoemaker said the energy released from just one of those fragments</DIV> <DIV>equalled all the nuclear weapons ever produced detonated at once in one location</DIV> <DIV>i would submit that with just those energies involved it would put rocks into space from earth</DIV> <DIV>jupiters atmosphere is quite thick/dense too! how many kms above Jupiters atmosphere did the plume</DIV> <DIV>from one impact produce? and the Venusian atmospheres thickness does not rival the depth those</DIV> <DIV>bolides penetrated on Jupiter!
