Quote:Now, let us turn to the content of the second point you made when you wrote, “This forum is for discussion of science. Period. “
Quote: I often agonize over pushing the envelope; what is not appropriate and what is necessary. [snip]To be less wordy, when others touch on things philosophical, theological, political, metaphysical, I attempt to invite a dialogue.
Quote:Jarad, is gravity gravity by whichever way it, gravity is formed?I mean is the "gravity" which comes from a planet weighing (whatever the weight of the earth is) creating a gravity of, let's call it "1"; is that gravity the same as the artificial gravity created by a spinning space station creating a gravitational effect of "1"?Otto
Quote:... is the gravity of a heavy body (e.g. the earth) the same as the gravity of the large spinning space station?

Quote:Seems to me that it would make sense to design the next LEO space station to rotate and generate artificial gravity as a test bed. Jarad
Quote:Mechanically, both result in force pushing down your body, putting stress on your bones and muscles. That's good enough for the purpose we want here.

Just send up a long cable on the next Russian launch, split it in two and start the pieces spinning; might as well get some useful science out of the thing.
Quote:The only good reason that I could see to do that one was to keep Russian missile builders off the black jobs market. Why would we think about building another? Or am I wrong, and we've gotten significant science out of it? More Teflon, or was it Tang?Unless NASA is hiring me to work on it; in that case I'm all for it. A friend of mine got fired for incompetence while managing a Chik-Fil-A store in Houston, and got a job at NASA as a procurement officer; he's bought billions of dollars of stuff, says it's lots of fun, says the fast-food job was too hard.

"The four points of the compass be logic, knowledge, wisdom, and the unknown. Some do bow in that final direction. Others advance upon it. To bow before the one is to lose sight of the three."
Quote: Quote:How about this one; let's assume the Red Planet (movie) thesis is true, that we are killing the earth and will make it effectively uninhabitable in a few generations; is it realistically possible to terraform Mars? And, is it possible to terraform Mars in a time span of benefit to us who are, hypothetically speaking, killing the earth? No and no. There's nowhere near enough gravity on Mars to sustain an atmosphere capable of supporting human life. Mars also has a weak and incoherent magnetic field, so what little atmosphere it has is vulnerable to further stripping by the solar wind, and its surface is bombarded by cosmic radiation. Not a very friendly place.

Quote: While it would be fun to go, I am unable to articulate a compelling business case that would convince a nation that the science value of this mission would be worth the cost.
