ATIG Members-

I'm sure many of you are aware of space architectures, such as propellant
depots, offering support to human spaceflight (HSF) beyond low Earth orbit
(LEO).  Such infrastructure would likely provide more return on investment
if it could be reused to facilitate multiple departures from LEO bound for
deep space.

Earlier this year, I researched how reusable infrastructure in Earth orbit
might assemble and service Mars-bound payloads during successive departure
seasons in 2020 and 2022.  The attached PDF file documents this research and
its findings.  It is bookmarked to aid navigation.  Your questions,
suggestions, and discussion of this work are invited.
