I was reading this:

It just seems that the Delta-V requirements - especially with a spacecraft that is stocked with supplies for a few years or for the Hohmann transfer helio-orbits - will make the amount of mass that needs to be lifted off from Earth overwhelming. That said, I suppose that stacking a launch vehicle in LEO would be similar to that for the ISS (albeit with the huge mass of the propellants) - but my experience working on the SSET has taught me that keeping the propellants at the right conditions would be a huge problem without the launch gantry. Would NASA take the risk and use SSSR Roman candles?
