[FPSPACE] Confusion on the Launch Pad

[David Portree]

Yes, I tend to agree. Has this been going on the whole time I was away?

Hi Jens -

>comes across, frankly speaking, like a load of bull!I have no idea how Baptistina got there, nor can 



I come up with an exact explanation for how it did. 



I've had a stroke, and far far better minds than 



mine work on the mechanics of comet capture. 







But since none of those people are likely to give you the 



time of day... 







Baptistina is what it is, a carbonaceous



chondrite. Asteroid formation is increasingly 



understood through the studies of meteorites, 



and nothing in meteoritics that I know of explains 



carbonaceous chondrites having an asteroidal origin. 







Thus, since you're looking at a dead comet, I suggest 



that you try to come up with Baptistina's capture



mechanism for yourself. 







Perhaps it will help you along if I point out to you



the difference in the eccentricities of comets Halley and 



SW 3 which you mentioned in your message. If you 



can figure out how that difference came about, 



then you'll be well on your your way to understanding 



Baptistina's capture mechanism.







You might want to start your studies by looking



at long period comets and short period comets, 



and the hypothesis concerning the capture 



mechanisms involved.







In any case, Jens, your rationalizations have 



nothing to do with the impact hazard. Once again 



ELEs are due to comets, and we know this



from ELE periodicity.







 In closing, Jens, denial is not simply a river 



in Egypt. About the only questions I have is why 



you're wasting my time with this, and the reasons



for your intensity. A first hypothesis is that you're



a manned Mars enthusiast who thinks that the US 



has nothing better to do with its money than fly 



a few men to Mars for a few days.

Its a dead comet fragment none the less.
