  1. Its not an efficient way to get water to mars, comet redirect would be better. But the point is that if people mindlessly throw themselves at mars, there will eventually be pockets of water underground (highly contaminated but we can deal with that in the Soilent green process) and walla . . . .water. Cometary water is not clean either, its got a number of contaminants that need to be cleaned up.
  2. If enough people buy tickets there will be alot of water on mars, gathered in 2 x 1 x 1 meter rectangular spaces. What was the name of that movie, Soilent green . . . .

    BC is between them, Cameroon county and the State of Texas. 12 miles out is US jurisdiction out to 200. Thus mostly internal affairs, legal beagles, the shipping lanes and laws that pertain to international shipping.
  4. Its still Sunday much of the ground operations and Admin aren't working anyway. The problem is for any operation at Kennedy is the sites range officer. So then it can trickle down to SpaceX Yeah if you happen to reach your 70th this week good luck collecting that first social security check in a few weeks.
  5. Excitonium!

    The excitonium-state lags in its return to the lowest ground state, at least until the entire system tolerates it. Its not really about charges after the electron is returned its about ground state seaking. In protein folding this is nothing new, some proteins take hours to find their ground states, the more complex or interconnected the overall structure, the longer it can take to reach that ground state, and when temperatures are 27 K you don't have the kinetic energy in the structure to push it over any thermodynamic humps. One thing that the article did not disclose is how long did the structure need to sit at that temperature or gradual lowering of temperature (remember entropy cannot be assessed in a state of disequilibrium) In some chemistry that translates into very slow lowering of thermal energy to shake things down to the minimal ground state for that temperature.
  6. I mostly agree, you would not use Lagrange points unless you had no alternative, the problem with Lagrange points is that to use them you essentially waste all the KE of LEO. The hamiltonian is KE-GPE. once KE-GPE = 0 for all intents in purposes past escape dV from LEO you pay one dV and get 4 dV back. So if you need 2500 dV to get to mars from L2 you need 500 dV to get to Mars from an escape orbit at LEO. But I should point out that there will be circumstances were you have to do it. This is the point I was making about function I was making regarding the shuttle that many missed. You don't have to man every facility in space, even if it is a manned facility. Transferring men to these places is the easy part (even SLS can do it, ROFL), when you need men on that station, the important part is to have enough stations such that STS-like systems are obsolete. Once you have the stations in stable orbit, lets say 5 to 7 covers all possibilities, the you can have robots on the stations and occasionally man them, and use any rated launch system. The problem is that the detractors of STS fail to realize, we don't have any facilities and we neither have STS and that is a loss of function. Even if you have 1 such system, you can leverage it to build 2 then 4 then 8. If the stations are ION powered you simply load them up with ARgon (for robotic stations magnesium will do) and send them to the desired elliptical. In addition you can send such a station to Mars and put it into orbit (number 8). It could serve two functions, one receiving crews from mars and then sending them back to Earth, the other repairing ships in transit. We might even have science satellites in martian orbits that occasionally need repairing. Here is an example, you have just collected rocks on Mars, you want to take the back to Earth Kelon Kusk has just donated the Mars hopper (a variant of the BFR) that gets us from mars directly back to Earth. NASAs planetary protection officer (a robust matronly woman wearing combat boots) who says, NO WAY YOUNG MAN, you are not bringing those muddy mars rocks into this house. But then research group X says BUT PPO WE NEED TO STUDY THEM. Here is where compromises come into play, so lets say we do have a base on the moon that has a safe room. Can we then transfer the rocks to the moon, so now we are not talking about breaking in the Earths atmosphere and all the risk that entails, we are talking about a few dV lost. So basically any ship that gets into LMO satisfies the criteria, and any ship traveling between the Mars and Earth satisfies the safety criteria, and any ship that can land on the moon satisfies the criteria (not necessarily manned). There is almost no difference in transporting to L2 or the moon a position above the moon, the dV differences relative to the dV to get from LMO to those orbits are small.
  7. Excitonium!

    Consider a hole to be a type of information, in this way it can be equated with other forms of matter and energy.
  8. SpaceX Discussion Thread

    Yeah thats right we didn't count the engines on OCISLU either.
  9. SpaceX Discussion Thread

    But the gods of counting engines and motors care.
  10. SpaceX Discussion Thread

    Yep " The Roadster is powered by a 3-phase, 4-pole, induction electric motor with a maximum output power of 185 kW (248 hp).[102] " Hey, but we still have the motors for the power windows. Also we can include the motors for the grid fins . . . .there are twelve of them (or 6)
  11. SpaceX Discussion Thread

    Oh yes, and so we can throw in a variable definition of an engine. " An engine or motor is a machine designed to convert one form of energy into mechanical energy." with modern usages as you stated that apply. I bet the tesla had electric windows . . . . .
  12. Random Science Facts Thread!

    Tell that to people living in the Greenland 742 years ago. Without anthropogenic climate change we really do not know how advanced the Ice Pack might be now. Don't forget that CO2 can also drive circulation and mixing, while the oceans are really basic, if the CO2 levels go to high on the benthic layers the expansion of H3CO2 into CO2 + H20 ---> CO2 gas (In upwellings approaching the surface) can drive the increase of the surface currents. Since CO2 is heavier than O2 and N2 when it displaces these from Ice, the hyper-saline density is higher and thus it falls more quickly from the arctic and antarctic. We are already seeing the consequences in the Pacific Northwest were the water is undergoing acidification. The greatest carbon sink was the perennial ice stores in the arctic (CO2 likes cold icy water) and this drove carbon to the benthic shelf which then dropped into the midatlantic (as the oceans warm in the tropics this will be faster). Since then it gets distrubuted around the world and reappears in the Major upwellings at periods of up to 10,000 years. The carbon 'pump' is likely to increase the rate markedly particularly as the CO2 potential of the deep oceans saturate. All signs are now that the Oceans carbon sink has begun to saturate.
  13. SpaceX Discussion Thread

    Yeah, that's good too, it confuses the hell out of people who are just anticipating that 3 x 9 = 27 or 28 or 32 or 102. Cause, like, you know, you wouldn't turn on a second stage engine or a car engine when your intent is to fire the first stage engines only.
  14. They didn't build the chunnel because waiting for boats made people relaxed and happy . . Be patient anyway, the Electron will blow up take off, I meant, in its own sweet time.
