What this article is about

This summary covers The Economist’s March 28th, 2026 Science & technology article listed in the contents as NASA's updated Moon-base plans and headlined on the page as Back to stay.

The article argues that NASA is trying to turn its Moon programme from an awkward, overcomplicated prestige project into something more durable. Instead of treating the next crewed landing as the main event, the agency now wants that landing to be the start of a longer campaign: repeated visits, more equipment on the surface and eventually a real base.

The simple version

NASA still wants to get astronauts back to the Moon, and it still wants to do it before China can claim the symbolic win of arriving first.

But the article says the agency is changing the more important question. The real goal is no longer just “who gets there first?” It is “who can stay, build and keep going?”

That shift matters because brief heroic missions are one thing; a repeatable space programme is much harder. It demands simpler logistics, more reliable hardware, lower costs and a clearer sense of what the Moon is actually for.

What NASA is now trying to do

Under Jared Isaacman, NASA has outlined a more concrete path toward a permanent presence on the Moon.

The new plan starts with a large number of robotic landers that will scout the lunar surface before astronauts arrive. Those missions are meant to identify and study possible base sites, so later crews are not landing half blind. After that, astronauts would return roughly every six months and gradually build out infrastructure with robotic help, including habitats that make longer stays possible.

That changes the meaning of the first crewed landing. In the article’s telling, it becomes less of a standalone triumph and more of an opening step in a wider construction project. If China were to manage a quick flags-and-footprints mission first, NASA could still argue that its own programme is more serious because it is designed around permanence rather than spectacle.

The big rethink behind Artemis

The article is blunt that Artemis in its older form was badly designed. It describes the programme as late, over budget and unnecessarily complex.

One obvious problem is the Space Launch System, or SLS, the huge rocket around which Artemis was built. NASA will keep using it for a few near-term missions, including the coming flight around the Moon and the first crewed lunar landings. But the agency is also looking for cheaper and more dependable commercial ways to get astronauts into space. That is an implicit admission that the original architecture is too expensive and fragile to support a long campaign.

Another major change is the downgrading of the Lunar Gateway, the space station that had been meant to orbit near the Moon. The article presents this as an important simplification. Gateway had become one more complicated stop in an already convoluted system. NASA now appears to think astronauts can transfer elsewhere, probably in low Earth orbit, without dragging that extra orbital outpost along.

In plain English, NASA seems to be stripping away pieces that looked impressive on paper but made the programme harder to execute.

Why nuclear power suddenly matters

One of the article’s most interesting points is that NASA’s rethink is not only about the Moon. It is also using this moment to push harder into nuclear technology for deep-space exploration.

A component originally built for Gateway, called the Power and Propulsion Element, is being reassigned to a Mars mission called SR-1. Instead of relying on solar panels, it would use a very small nuclear reactor. That would make it NASA’s first spacecraft to carry a reactor and the first to use one for propulsion beyond Earth orbit.

The mission itself sounds ambitious but also practical. When SR-1 reaches Mars, it is meant to release small helicopter drones to scout possible landing areas for future astronauts. More importantly, though, the article treats the mission as a technology pathfinder. If NASA can prove out reactor-based propulsion, radiation shielding and heat-management systems, those tools could later support Moon-base operations and eventually human missions to Mars.

So the Moon-base plan is really part of a broader argument inside NASA: if America wants a lasting presence beyond Earth, it needs infrastructure and power systems that can support sustained operations, not just short visits.

Why the article is still cautious

Despite the excitement around the new plan, the article is not naively optimistic.

Its central caution is that NASA has a long history of turning promising ideas into delayed, overpriced programmes that become politically vulnerable. The agency’s challenge is not to produce an inspiring slide deck. It is to show enough visible progress before the next presidential transition in January 2029 that the whole effort becomes harder to cancel or hollow out.

That is why speed matters so much. A string of robotic lunar missions, tangible progress toward a base and a nuclear spacecraft on its way to Mars would create facts on the ground, or at least in space. Without that momentum, the programme could slip again, costs could swell and China might not only win the symbolism of the next landing but also expose America’s inability to execute.

The takeaway

The article sees NASA making a sensible correction.

Rather than obsessing only over the next dramatic lunar landing, it is trying to build a programme that can survive for years and justify itself as real infrastructure. Cutting back on cumbersome ideas, leaning more on commercial providers and investing in nuclear power all fit that logic.

But the underlying verdict is conditional. NASA now appears to have a better theory of what it is trying to do. Whether it has the institutional discipline to do it quickly and affordably is still the real test.
