This 1.5-hour lecture reviews major challenges to interplanetary human spaceflight and suggests strategies by

which they may be addressed. These strategies include pre-emplaced Earth return consumables at the

interplanetary destination, water used as a high-efficiency/high-thrust propellant also serving as crew radiation

shielding, and transport servicing in a distant retrograde orbit about the Moon. Applied to a hypothetical

transport christened Aquarius, the strategies are shown to enable routine and sustainable roundtrips between

Earth and Deimos, the outer moon of Mars. Knowledge gaps pertaining to Aquarius are identified with the

intent of motivating changes in current technology roadmaps. After listening to this lecture, anyone with

interplanetary human spaceflight interests will be conversant with associated technology issues and plausible

means by which they might be resolved.

Mr. Adamo is an astrodynamics consultant focused on space mission trajectory

design, operations, and architecture. He works with clients primarily at NASA and

in academia.

Until retirement in 2008, Mr. Adamo was employed by United Space Alliance as a

trajectory expert, serving as a “front room” flight controller for 60 Space Shuttle

missions. Along with console duties during simulations and missions, this job

entailed development of trajectory designs, software tools, flight rules, console procedures, and operations

concepts. Mr. Adamo began his career at the Perkin-Elmer Corporation where he developed and operated

proof-of-concept software for computer-controlled polishing of optical elements. He has degrees in Physical

Sciences and Optical Engineering from the University of Houston and the University of Rochester, respectively.

Mr. Adamo is a Senior Member of AIAA and the author of many publications. He has received numerous

awards, including 14 NASA Group Achievement Awards.
