HLO because Orion can't reach LLO. That was my undestanding.

Steven, that PDF is superb! It even gives delta/v (post TLI) round trip to the various orbits. That's a data point I've been trying to figure out how to figure out (to see what over vehicles might be viable) and here it is. Lar, you're right, LLO is well beyond the capabilities of Orion; it is designed to have a total delta/v potential of 1250 m/s, while RT to LLO takes 1800 m/s.
Question what's te purpose of a new Canadarm on the DSG?Is it's main purpose to assemble the DST's when that program is approved?
