> HLS requires on-orbit refueling. Anything from 10 to 20 refueling launches will be required. Did you think it required one refueling launch? The SH+SS stack will never be reusable or reliable enough to accomplish the refueling operation in time and on budget.

>This means one moon mission will require the use of 10 launch pads

The refueling ships are to be launched weeks/months in advance, one at a time. If you look at the rate of Falcon launches this is nothing out of the ordinary.

Yeah and how many refuelings have they done yet?

[ricardobeat]

It's a system in development. Do you want to compare to the SLS timeline? 15 years in development, 30 billion spent, with a single test launch.

Just because one failed to deliver results doesn't make the alternative automatically the selection.
