Evolvable Lunar Architecture is a well thought plan for lower risk for moon and Mars development while lowering cost by ten times

A study by NexGen LLC looked at a lower cost approach to explore the moon and Mars.

Thestudy’s primary purpose was to assess the feasibility of new approaches for achieving our national goals in space. NexGen assembled a team of former NASA executives and engineers who assessed the economic and technical viability of an “Evolvable Lunar Architecture” (ELA) that leverages commercial capabilities and services that are existing or likely to emerge in the near-term. They evaluated an ELA concept that was designed as an incremental, low-cost and low-risk method for returning humans to the Moon in a manner that directly supports NASA’s long-term plan to send humans to Mars. The ELA strategic objective is commercial mining of propellant from lunar poles where it will be transported to lunar orbit to be used by NASA to send humans to Mars.

This plan can affordably

* Get humans back to moon by 2020-2023
* Get a permanent manned lunar base by 2030-2035

Based on these assumptions, the our analysis concludes that:
• Based on the experience of recent NASA program innovations, such as the COTS program, a human return to the Moon may not be as expensive as previously thought.

• America could lead a return of humans to the surface of the Moon within a period of 5-7 years from authority to proceed at an estimated total cost of about $10 Billion (+/- 30%) for two independent and competing commercial service providers, or about $5 Billion for each provider, using partnership methods.

• America could lead the development of a permanent industrial base on the Moon of 4 private-sector astronauts in about 10-12 years after setting foot on the Moon that could provide 200 MT of propellant per year in lunar orbit for NASA for a total cost of about $40 Billion (+/- 30%).

• Assuming NASA receives a flat budget, these results could potentially be achieved within NASA’s existing deep space human spaceflight budget.

• A commercial lunar base providing propellant in lunar orbit might substantially reduce the cost and risk NASA of sending humans to Mars. The ELA would reduce the number of required Space Launch System (SLS) launches from as many as 12 to a total of only 3, thereby reducing SLS operational risks, and increasing its affordability.

• An International Lunar Authority, modeled after CERN and traditional public infrastructure authorities, may be the most advantageous mechanism for managing the combined business and technical risks associated with affordable and sustainable lunar development and operations.

• A permanent commercial lunar base might substantially pay for its operations by exporting propellant to lunar orbit for sale to NASA and others to send humans to Mars, thus enabling the economic development of the Moon at a small marginal cost.

Historically, the human mission cost beyond Earth’s orbit have been dominated by launch cost. However, the cost reduction revolution started by SpaceX with their Falcon launch vehicles and being matched by ULA’s Vulcan launch vehicle development will usher in a new era for human exploration. Launch cost is dramatically being reduced and may become a fraction of the mission cost rather than the dominating cost factor. For this study, the Falcon 9 and Falcon Heavy were used as representative of the new trend in launch costs because of the violable prices on the SpaceX web site. SpaceX currently operates the Falcon 9 that has a payload of 13.1t to LEO at 28.5° at a per launch cost of $62.1M ($4750/kg) as per there Web site. This compares to the Saturn V that delivered 130t at $46,000/kg. The economy of Falcon 9 is based on the large number of planned launches per year; as of 2016 there are 21 launches currently sold. In addition, SpaceX is actively developing a reusable Falcon 9 that should further reduce costs.

In addition, SpaceX is developing the Falcon Heavy using 3 modified Falcon 9 cores and the Falcon 9 second stage. Falcon Heavy has an advertised payload to LEO of 53t at a cost of $90M ($1700/kg).
