Manned Mars Mission and terminal illnes
AstronautGeologist replied to Pawelk198604's topic in Science & Spaceflight
When I get to Mars I'll tell you. Edit: Have you ever read Ben Bova's Mars? The astronauts all get their appendixes removed before the mission for that reason. -
Selecting Mechjab parts.
AstronautGeologist replied to Gary_P's topic in KSP1 Gameplay Questions and Tutorials
MechJeb .20 sucks. So I downloaded the .19 version at the store so I could get the .19 MechJeb. -
Question: doesn't iodine need starch to become a purple gas? Short Answer: Iodine - gaseous, is purple. Starch makes it purpleier, purpler; more purple. Long Answer: Starch is not required. (what's your science teacher smokin'? lol, aren't science teachers supposed to know what they're talking about?) Iodine is a gray/black solid which, when heated, sublimates; that is, it goes directly to the gas/vapor phase without becoming a liquid in between. Iodine gas/vapor is purple and so is iodine when dissolved in a non-polar solvent like carbon tetrachloride or benzene. The purple color indicates the presence of iodine and starch is not required. The reaction of iodine with starch is different; it reacts with starch to form a blue-black complex compound that isn't the same color as the purple gas/vapor.

The heavier elements differentiate towards the core of a planet hence most of the iodine would be in the core, just as most of the iron, nickel, gold, uranium, thorium, etc. Perhaps Eve got torn up by something leaving only the core. Of course, it wouldn't just be iodine, it would also be iron, nickel, gold, uranium, thorium etc. Iodine is also produced by neutron bombardment of Xenon which in itself is a byproduct of Uranium decay so perhaps it's the leftover of a giant nuclear reactor, note a planetary core and mantle is a giant thorium/uranium fission reactor. There's also neutrons from cosmic ray spallation where cosmic rays hit something sending neutrons flying. It would take tens of billions of years for the thorium and uranium of a leftover planetary core to decay into xenon and get bombarded into iodine so such a planet could not be part of a star's planetary system, stars don't live that long, it would have to be the leftover core of a rogue planet, perhaps the leftover core of a brown dwarf star. Short of a passing neutron star or black hole, I can't imagine what could strip the rest of such a planet away.

Not really, because most other 14 year olds I know are too obsessed with video games, masturbation, and music videos. Apparently we like Kate Upton's "hot bod" and Black Ops II more than exploring new worlds and going where no man has gone before.
