Orbital ATK has unveiled a practical new proposal to build a near term manned outpost in lunar orbit that could launch by 2020 and be operational in time for a lunar link-up with NASA’s Orion crew module during its maiden mission, when American astronauts finally return to the Moon’s vicinity in 2021 - thus advancing America’s next giant leap in human exploration of deep space.
The intrepid offer by Orbital could be carried out rather quickly because it utilizes an evolved version of the company’s already proven commercial Cygnus space station resupply freighter as “the building block … in cislunar space,” said Frank DeMauro, Orbital ATK Vice President for Human Spaceflight Systems, in an exclusive interview with Universe Today. See an artist concept in the lead image.
“Our Cygnus spacecraft is the building block to become a vehicle for exploration beyond low Earth orbit,” Orbital ATK’s Frank DeMauro told Universe Today.
“We are all about supporting NASA’s Mission to Mars. We feel that getting experience in cislunar space is critical to the buildup of the capabilities to go to Mars.
NASA’s agency wide goal is to send astronauts on a ‘Journey to Mars’ in the 2030s - and expeditions to cislunar space in the 2020s serve as the vital ‘proving ground’ to fully develop, test out and validate the robustness of crucial technologies upon which the astronauts lives will depend on Red Planet missions lasting some 2 to 3 years.
Orbital ATK’s lunar-orbit outpost proposal was announced at an official hearing of the US House of Representatives Subcommittee on Space on Wednesday, May 18, by former NASA Astronaut and Orbital ATK President of the Space Systems Group, Frank Culbertson.
“A lunar-orbit habitat will extend America’s leadership in space to the cislunar domain, said Orbital ATK President of the Space Systems Group, Frank Culbertson.
“A robust program to build, launch and operate this initial outpost would be built on NASA’s and our international partners’ experience gained in long-duration human space flight on the International Space Station and would make use of the agency’s new Space Launch System (SLS) and Orion deep-space transportation system.”
The idea is to assemble an initial crew-tended habitat with pressurized work and living volume for the astronauts based on a Cygnus derived vehicle, and have it pre-positioned and functioning in lunar-orbit by 2020.
As envisioned by Orbital ATK, the habitat would be visited during NASA’s first manned mission of SLS and Orion to the Moon known as Exploration Mission-2 (EM-2).
The three week long EM-2 lunar test flight could launch as early as August 2021 - if sufficient funding is available. The goals of EM-2 and following missions could be significantly broadened via docking with a lunar outpost.
The initial lunar habitat envisioned by Orbital ATK would be comprised of two upgraded Cygnus pressurized vehicles - provisionally dubbed as Exploration Augmentation Modules (EAM). They would be attached to a multi-port docking module very similar in concept and design to the docking Nodes already flying in orbit as integral components of the ISS.
The habitat components would be launched to the Moon on a commercial launch vehicle.
High on the list of candidate launchers would be the United Launch Alliance Atlas V rocket which recently already successfully delivered two Cygnus cargo ships to the ISS in Dec. 2015 and March 2016.
Other potential boosters include the ULA Delta IV and even ESA’s Ariane V as a way to potentially include international participation.
The habitat components could be manufactured and launched about three years after getting a ‘Go Ahead’ contract from NASA.
Over time, the outpost could be expanded with additional habitat and research modules delivered by Orion/SLS, commercial or international rockets.
Cygnus is suitable for wide ranging science experiments and gear. It could also launch cubesats - like the current Cygnus berthed at the ISS is equipped with a cubesat deployer. Lunar landers could dock at the open docking ports.
“We are doing science now on Cygnus and we would expect to carry along science experiments on the new Cygnus vehicle. The vehicle is very attractive to science experiments,” DeMauro explained.
“There really is no limit to what the outpost could become.”
“What we put out is very exciting,” DeMauro noted.
“As a company we are looking forward to working in this arena. Our suggested plans are in line with where NASA wants to go. And we think we are the right company to play a big part in that!”
By incorporating commercial companies and leveraging the considerable technology development lessons learned from Cygnus, NASA should realize significant cost savings in implementing its human exploration strategy. Although Orbital ATK is not divulging a cost estimate for the lunar habitat at this time, it should be considerable and the 3 year time frame to launch is very attractive.
Orion is designed to send astronauts deeper into space than ever before, including missions to the Moon, asteroids and the Red Planet. Cygnus derived modules and/or other augmenting hardware components will be required to carry out any round trip human missions to the Martian surface.

I love the idea.
