  1. Maybe us KSPers should band together and enter a groundbreaking, totally awesome design into a rover contest?
  2. You don't hear much about manned Chinese launches.
  3. Yeah right. Us Earth-dwellers are going to end up watching them sit around with their bones and muscles decaying into nothingness. It'll be grisly.

  6. Iodine vaporizes into a lovely purple gas which also happens to be quite toxic!
  7. Ditto 100%. I want to be an astronaut when I 'grow up'.
  8. Why is Eve's atmosphere purple? "The atmosphere is possibly composed of iodine, given its purple coloration. " -KSP wiki page for Eve The Evian atmosphere is likely composed of iodine. Iodine is a black solid element under standard conditions. Iodine goes from a solid straight to a purple gas, with no liquid stage that can easily be detected. Iodine, in the solar system is rare, and in Earth's crust its abundance ranks about 53rd at 0.450ppm to 0.500ppm. Origin of Iodine on Eve: Iodine has an atomic number of 53 placing it on the periodic table above Iron, Cobalt, and Nickel. Therefore its only produced in a supernova explosion. Large concentrations of iodine might be possible naturally in a region of the galaxy where supernova explosions happen frequently or from the remnants of a supernova of an exceptionally large star. 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. A planet with an iodine atmosphere would have to have a very hot surface for pure iodine as a gas as iodine is a solid at standard temperature and pressure. Eve seems to meet the temperature criteria, since its surface temperature ranges from 40 to 150 degrees Celsius. The melting point of Iodine is 113.5 degrees Celsius. Iodine, being one of the halogens, is a fairly reactive substance. The issue is that absent any processes to maintain the environment out of equilibrium, everything that can react with iodine will have reacted with iodine. Life will maintain the environment in such a non-equilibrium state, but the prospects for lifemay be poor. Geological processes could also do it, by bringing up substances that the iodine will react with. As for specific reactions, it reacts violently with some metals including aluminium, but of course those metals are unlikely to occur naturally in their pure state. a possible reaction then might be that of hydroiodic acid and carbonate rocks. Carbonate rocks on Earth are mostly biological in origin, but some are igneous so could occur on Eve (does Eve has volcanoes?). Hydroiodic acid is made by dissolving hydrogen iodide in water. Hydrogen iodide can be made by reacting elemental iodine with hydrogen or hydrogen sulfide gas, either of which can come out of volcanoes. The iodine-hydrogen reaction is accelerated by exposure to yellow light, giving an interesting means to control the reaction. Looks like Eveian atmosphere to meh.
  9. OMG I just realized I was staring at that lander for 10 minutes. LOL IT IS FANTASTIC! THAT IS THE ONLY LANDER I'LL EVAH NEED EVAH!!!!
  10. Whatisthisidon'teven......................? Putting the fuel and stuff inside the panels is... genius. idon'teven.... it just.. I...... beautiful.. realistic. amazing.... idon'teven........ U ARE A GENIUS I wonder if im the only one who feels like a miserable failure in life after seeing this engineering marvel
  11. I'm trying to put in MechJeb and KAS and a hundred other mods but It doesn't work anymore!
