Preparations for Next Moonwalk Simulations Underway (and Underwater)
When companies began approaching NASA’s Langley Research Center, asking to be included in the In-Space Servicing, Assembly, and Manufacturing (ISAM) State of Play for access to competitive intelligence, the team knew they had crossed an inflection point.
“We’ve had some unnamed companies ask if we have any proprietary information,” says Dale Arney, senior team lead for the ISAM Technology Portfolio at NASA Langley. The answer is “no,” but that impartiality is precisely what makes the State of Play invaluable to an industry trying to understand a rapidly expanding field.

Published since 2021, the 2026 edition has grown to 368 pages documenting current ISAM capabilities across 11 functional areas, from robotic manipulation to refueling and structural assembly. The document serves as both encyclopedia and roadmap for the technologies that will enable spacecraft to be serviced, assembled, and manufactured in orbit rather than launched as integrated systems.
“The field itself has expanded more than linearly since we started,” Arney explains. What began as a tool to ensure NASA centers shared a common reference point has become the industry’s go-to resource for understanding what’s possible versus what’s still conceptual.
The State of Play team maintains strict entry criteria: hardware must physically exist, either as ground prototypes or in-flight demonstrations. “We get people who will send their PowerPoint presentation of their technology idea,” Arney notes. “There’s no real indication they’ve done any work on the technology itself yet.” Those concepts don’t make the cut until the following year’s review.
This rigor matters, because ISAM capabilities will enable missions impossible with traditional single-launch approaches. Future missions will require telescopes larger than any launch vehicle fairing, persistent national security assets that are mobile and resilient, and commercial systems that can upgrade to the latest technology on orbit without full replacement.
The document is intentionally collaborative. “We like to refer to it as kind of a crowdsource document,” says team member John Mulvaney. Each year brings more interviews with industry partners to ensure accuracy and completeness. Contributions come from NASA centers including Ames, Glenn, Marshall, Kennedy, and Johnson, along with international developers meeting the hardware criteria.
The result is more than a technical reference. The 2026 edition includes developer profiles and facilities documentation, providing mission designers with not just what’s possible but who’s doing it and where the work happens. For companies entering the ISAM ecosystem or expanding their capabilities, it offers both competitive context and collaboration opportunities.
As the space industry moves toward more ambitious missions, from lunar infrastructure to on-orbit manufacturing, the ISAM State of Play provides the shared vocabulary and capability baseline that emerging ecosystems require. It’s not speculation about the future; it’s documentation of what exists now and where the hardware is heading next.

“I want to be able to look at a rocket launch and say, ‘I touched a piece of this.’”
That’s how Richard Spolzino describes the thing he’s chasing. Not a title, not a specific mission, not even NASA itself, just the ability to point at something real and know his work made it possible. At NASA’s Langley Research Center in Hampton, Virginia, Spolzino works within Moon Base’s mission architecture and systems interoperability effort, helping identify what NASA still doesn’t know about the Moon and Mars, and making sure that missing information gets found before it becomes a problem.

“For me, it kept coming back to where can I have the most impact? Where can my work touch the most things?“
From History to Aerospace
Spolzino didn’t set out to end up here.
He started college as a history major. He switched to a physics track at Santa Clara University, thinking he’d end up in astrophysics. A research stint at Lick Observatory studying interstellar dust polarization taught him two things: the work was fascinating and, “I don’t think the staying-up-all-night thing is for me,” he says.

After graduation, he started down the path of Officer Candidate School in the Navy, hoping to fly jets. It didn’t pan out, and that detour led him to a graduate program at the University of Houston, combining aerospace engineering and space architecture — not the habitat-design kind of architecture people usually picture, but the systems-level kind, where a lunar oxygen plant connects to the rovers that feed it, which connect to the processor, which connects to the user drawing down the resource. “I was always more attracted to how all the pieces work together than to any single piece,” he says.
Chasing Impact
Ask Spolzino if he dreamed of working at NASA, and the honest answer is no.
“I really admire people who’ve had that drive their whole life,” he says. “For me, it kept coming back to where can I have the most impact? Where can my work touch the most things?” A University of Houston program with strong ties to Johnson Space Center put NASA on his radar alongside other options in industry and government. What ultimately drew him in wasn’t the agency’s name, it was the scope of the problems and the direct line he saw to senior decision-makers shaping the return to the Moon.
That’s also, he adds, exactly why NASA is worth considering for people who aren’t sure it’s their calling yet. The culture rewards people willing to take on more than their assigned lane and gives early-career employees room to grow into problems bigger than their job description, something he says he might not have found moving up more slowly in industry.
Documenting the Missing Piece
Spolzino’s day-to-day work centers on a deceptively simple idea: the data gap.
“You can think of it as synonymous with a knowledge gap,” he explains. “It’s a way of documenting the thing we don’t know.” Take the geotechnical properties of lunar regolith — moon dust, essentially, but the specifics matter enormously. How much weight can it bear? What’s its shear strength? Answering those questions shapes everything from how far a rover can safely drive to whether a habitat’s foundation will hold.
A data gap lays that out formally: what we don’t know, why it matters, what we currently have that falls short, and, critically, a specific measurable target industry and international partners can aim for. “Once we’ve identified what’s missing,” he says, “our partners can look at that list and see exactly where their contribution would be valuable.”
His team started with roughly 25 published data gaps last year. They’re on track for 60 by the end of this year.
From Concept to Cargo
The concept only matters if it changes decisions, and Spolzino cites two recent examples where it did.
When the lunar lander company now known as Voyager (formerly Astrobotic) was preparing its upcoming Griffin-1 mission, the team didn’t help them figure out what instruments to fly since that was already locked in. Instead, Spolzino’s team helped them prioritize what data gets sent home first through a communication pipeline that can’t carry everything at once. “How do you prioritize all the things you say you want, and what gets sent back through that constrained pipeline?” he asks.

On the other side of the pipeline, Spolzino has spent recent months evaluating proposed instruments (spectrometers, sample collection tools, tech demonstrations) against the published data gaps to help leadership decide what’s worth flying. Some proposals map cleanly onto a documented need. Others don’t align with anything NASA has said it’s missing. “That’s used to filter down what gets pushed forward as a real candidate,” he says. Industry partners have taken notice, and leadership now asks companies pitching new instruments to show how their proposal maps to a data gap before the conversation goes any further.
Figuring It Out Takes Work
Spolzino admits the job reshaped an assumption he carried out of graduate school — that NASA had everything figured out, and that the agency’s reputation meant every question already had an answer somewhere inside its walls.
Three years in, he sees it differently. “Keeping the kind of reputation NASA has takes constant, deliberate work,” he says. “Everyone’s genuinely trying to pull in the right direction, but it’s not automatic.” That realization was clarifying for him. The agency runs on people figuring things out in real time, which means there’s room for someone early in their career to contribute meaningfully, rather than just executing someone else’s playbook.
His advice to students considering NASA is practical, not sentimental: Grades matter less than people think. “The projects you work on, and the results of that work, are what people look at first,” he says. His advice is to join clubs, take on real projects, and build something. “It’s less about credentials and more about giving yourself something to show up with.”
On Spolzino’s Sci-Fi Shelf
The Three-Body Problem trilogy by Liu Cixin
Spolzino was already deep into the second book, The Dark Forest, on a flight from New York to Houston when the plane was diverted to San Antonio. “I did not care that I was three or four hours late,” he says. “I had that book, and I was just devouring it.”
Kerbal Space Program
An older game, but a formative one. Spolzino credits it with cementing his interest in space before college even started. “It’s a space program simulator where you build rockets piece by piece, and the physics are simplified but accurate enough that you’re doing a lot of the same math as an actual mission design tool,” he says. “That really had a huge impact on me figuring out that space was the thing I wanted to do.”
