quote: What I think NASA should be doing is releasing some sort of "5 Star Safety rating" for space rockets, e.g. fire retardant electrical wiring, not use 100% oxygen atmosphere, not have lumps of ice form on one part of the rocket that can fall off and damage re-entry shielding during launch, making sure the rocket can be launched in the lowest known temperature at Florida (or wherever), making sure all interworking modules use the same units (e.g. all metric units), making sure oxygen tanks won't explode when the stirring motor is turned on, guarantees the fuel tanks will be filled to the brim at lift off, no re-entry shield failure during re-entry, etc. I think they should do that, and then if Musk (or whoever) gets 5 stars, then it's pretty obvious his rocket is about as safe as it can get, but if he gets two, then the American public can understand why NASA won't commit themselves to using that rocket.
