Overview of the Artemis Architecture

Today’s episode of STEM-Talk features a timely and wide-ranging discussion with Drs. Michael Griffin and Lisa Porter about NASA’s plans to return humans to the Moon, the history of lunar missions, and how China’s advances in space technology pose a serious threat to U.S. national security.

IHMC founder and CEO Emeritus Ken Ford’s interview with Griffin and Porter came 10 days before Griffin appeared before the U.S. House Committee on Science, Space and Technology to give testimony on China’s advancements in space and the risks it poses for the United States.

“We have squandered a 60-year head start on pioneering the space frontier to a nation that, without reason or provocation on our part, has chosen to become our nation’s adversary,” said Griffin in his opening comments to Congress.

In this episode, Griffin and Porter explain why it is critical for the U.S. to return to the Moon before China. They also argue that NASA’s Artemis III mission to return to the lunar surface and establish a permanent base on the Moon is seriously flawed and should be scrapped.

Griffin and Porter are co-founders and co-presidents of LogiQ Inc., a company providing high-end management, scientific and technical consulting services.

Griffin’s background includes roles as the former Undersecretary of Defense for Research and Engineering, the Administrator of NASA, the Space Department Head at the John Hopkins University Applied Physics Laboratory as well as Chairman and CEO of Schafer Corporation.

Porter’s background includes roles as the former Deputy Undersecretary of Defense for Research and Engineering, the founding Director of the Intelligence Advanced Research Projects Activity (IARPA) in the Office of the Director of National Intelligence, and the Associate Administrator for Aeronautics at NASA.

[00:04:44] Ken opens the interview by welcoming Mike back to STEM-Talk, who was a guest on Episodes 23 and 134. He also welcomes Lisa to her first appearance on STEM-Talk and asks her to talk about her decision to major in nuclear engineering at the Massachusetts Institute of Technology.

[00:08:50] Ken asks Lisa why she went to Stanford for a Ph.D. in physics.

[00:10:43] Ken explains that Lisa was the founding director of the Intelligence Advanced Research Projects Activity (IARPA), a department within the Office of the Director of National Intelligence. Ken asks about some of the challenges the American intelligence community faced that she addressed as director of IARPA.

[00:16:15] Ken asks about Lisa’s time working for Mike as Associate Administrator for Aeronautics at NASA, and how she came to accept that role.

[00:18:07] Ken explains that when Mike became Undersecretary for Defense for Research and Engineering in 2018, he invited Lisa to become the Deputy Undersecretary for Defense for Research and Engineering. Ken asks Mike why Lisa was ideal for that role.

[00:21:07] Ken explains that Mike and Lisa are working together again as co-founders and co-presidents of LogiQ Inc., a company that provides scientific consulting services. Ken asks Mike to give a brief overview of LogiQ’s work.

[00:24:44] Ken shifts the discussion to space exploration, noting that he wants to talk about Mike’s 2024 congressional testimony on returning to the Moon, and a paper that he and Lisa published titled “A system architecture for human lunar return.” To begin the discussion, Ken asks why it is so important for us to return to the Moon.

[00:29:11] Ken asks Mike and Lisa to explain why it is important for the US to be the first to return to the Moon in the context of China’s ambition to send humans to the Moon and establish a permanent lunar presence.

[00:33:24] Ken asks Mike and Lisa if they see the cancellation of the Apollo program as a mistake.

[00:35:36] Ken asks Mike and Lisa to give an overview of the Artemis program.

[00:41:45] Ken mentions the centrality of the Gateway in the Artemis plan, and the problem with making something that is already hard even harder for no good reason.

[00:43:28] Ken mentions his concern that the focus on a Mars-forward approach might impede our success with the current Moon missions.

[00:46:40] In Mike and Lisa’s aforementioned paper, they propose a dual-launch lunar landing architecture, which is simpler than the current NASA architecture and presents lower risks to the crew. Ken asks Mike and Lisa to elaborate on this idea.

[00:48:41] Ken asks Mike and Lisa what they think are some of the other technical and programmatic problems with the current Artemis plan.

[00:52:31] Ken asks Mike and Lisa what NASA’s response has been, as well as the response of others in the human space flight community, to their paper and recommendations for the Artemis mission architecture.

[00:54:25] Ken explains that Sean Duffy, the Secretary of Transportation and acting NASA administrator, has opened the door to some additional lander ideas in light of concerns that the two current contractors, Space X and Blue Origin, may not be ready in time for the current Artemis schedule. Ken asks if Lisa and Mike think this is a good idea or if they think it would further complicate matters.

[00:59:25] NASA’s current budget is around $24.9 billion dollars, approximately 0.4 percent of total federal spending. Ken notes at a time when China is increasing their investment in their space programs and launching several missions, NASA is facing a proposal to cut its funding by 24 percent to $18.8 billion. Ken asks Mike and Lisa for their thoughts on this.

[01:03:13] Ken and Lisa continue Mike’s discussion on the core purpose of NASA beyond science.

[01:08:55] Ken and Mike reflect on Ken’s observation that the U.S. is not as serious about space and the Moon as it was during the Apollo years, years that attracted the nation’s best and brightest.

[01:09:39] Ken asks Mike and Lisa their thoughts on the way that NASA is contracting more services in the development of Artemis, rather than funding a development program.

[01:15:55] Ken wraps up the interview by commenting that he believes listeners will very much enjoy today’s conversation.
