future space systems growth requires
improving multiple elements. This
includes the vehicles, space systems, spaceport, organizations and their
processes. It requires all of these be optimized,

working from a whole systems perspective, building on the
lessons of the past - that is our emphasis in the next
generation of space systems designs.

Program and Implications for Future NASA Missions," September 2017
"The goal here is to do the math, to bring
rigorous life cycle cost (LCC) analysis into discussions about COTS
program costs. We gather publicly available cost data, review the data
for credibility, check for consistency among sources, and rigorously
define and analyze specific cost metrics."
Edgar Zapata, "The Opportunity in Commercial
Approaches for Future NASA Deep Space Exploration Elements," September
"This work joins the previous two events,
showing the potential for commercial, public private partnerships,
modeled on programs like COTS, to reduce the cost to NASA significantly
for “…other required deep space exploration capabilities.”
Edgar Zapata, "NASA Human Spaceflight Scenarios -
Do All Our Models Still Say ‘No’?," September 2017
"Assuming the value of long-term life cycle cost
analysis, where due diligence meets reconnaissance, and accepting past
shortcomings, the work here approaches life cycle cost analysis for
human spaceflight differently."

"This study, conducted by a team of leaders in
industry, research and development, finance, policy and strategy,
explores whether and how the USAF can form private sector
partnerships to create a virtuous cycle of launch cost reductions of
between 3 and 10 times lower than today’s costs. Doing so
could enable completely new approaches for the Air Force to defend
American values, protect American interests, and enhance opportunities
to exploit the unique global advantages of the ultimate high ground."

commercial missions to the lunar surface for NASA primary payloads,
NASA secondary payloads, or NASA hosted payloads, with the potential to
also procure data from any commercial lunar surface missions and/or
return payloads or samples to the Earth."

Though not on space transportation per se, this
papers observations on the unsustainable difference between project cost
inflation vs. increases in project budgets applies just as
well. Reduced launch cost and approaches for cheaper spacecraft,
including commercial paths, are presented.
"But we are in trouble. Our telescopes have
grown in expense far faster than the economies they depend on. “If
something cannot go on forever, it will stop” as Herbert Stein’s Law
states in economics."
"But the price was high. Figure 3 shows how the
(inflation-corrected) cost of these missions increased by a factor of
about 20 over 30 years. This is an exponential growth rate of 10% per
year. The same plot for other wavelength bands would be much the same.
Ian Crawford has shown that Mars landers have grown even faster, at
about 15% per year. Historical growth rates for the US GDP have been
fairly steady at about 2% a year for the past century and more
(1871–2001). Clearly, growth rates for astronomy that are four
times faster than that of the economy are unsustainable."
