NASA Seeks Alternative Moon Landers as SpaceX Falls Behind Schedule

You can't invent anything new. Anything you use has to already exist.
A former NASA official explains the only way to build a lunar lander in under five years.

In the shadow of a renewed space race, NASA has opened its lunar lander competition beyond SpaceX, acknowledging that ambition alone cannot outpace the limits of engineering. With China aiming for the moon by 2030 and a presidential deadline set for January 2029, the agency is no longer willing to place its entire bet on a single rocket that has yet to demonstrate its most critical capabilities. The question now is not which vision is boldest, but which path is most likely to carry human beings safely to the lunar surface before history is written by someone else.

  • SpaceX's Starship — a vehicle requiring orbital refueling never demonstrated at scale — has fallen behind schedule, leaving NASA's crewed moon landing timeline dangerously exposed.
  • A two-front deadline is compressing every decision: China is targeting a lunar landing by 2030, and President Trump wants an American crew on the moon before his term ends in January 2029.
  • NASA administrator Sean Duffy has thrown the lander contract open to competitors, with Blue Origin and Lockheed Martin now invited to make their case against the incumbent.
  • Lockheed Martin is proposing a pragmatic alternative — a smaller, Apollo-inspired two-stage lander assembled from hardware that already exists, rather than technologies still being invented.
  • The space industry is converging on a single uncomfortable truth: with less than four years on the clock, novelty is a luxury no one can afford.

NASA is no longer willing to wait for SpaceX alone. Acting administrator Sean Duffy announced this week that the agency would open bidding for a lunar lander contract to additional companies, citing SpaceX's schedule delays and the mounting pressure of two simultaneous deadlines — China's stated goal of landing astronauts on the moon by 2030, and President Trump's desire to beat them before his term ends on January 20, 2029.

SpaceX won a $2.9 billion contract in 2021 to build the Artemis III lander using a version of its Starship rocket. But the architecture has proven far more complex than anticipated. Three consecutive test flights failed this year, and the program's central challenge — refueling Starship by docking with other Starships in Earth orbit — has never been demonstrated at scale. Even former NASA administrator Jim Bridenstine told Congress that the Starship approach "doesn't make a lot of sense if you're trying to go first to the moon to beat China."

Elon Musk dismissed the concerns on X, insisting SpaceX was moving faster than any competitor and that Starship would ultimately handle the full mission. He also noted that Blue Origin, now being invited to compete, has never delivered a payload to orbit. That is true — though Blue Origin holds a separate $3.4 billion NASA contract for Artemis V, a mission not scheduled until the 2030s and too late for the current political window.

Lockheed Martin is offering a different philosophy entirely. Rather than developing new technology, the company is proposing a lander assembled from hardware that already exists — a two-stage design echoing the Apollo lunar modules, with crew components drawn from the Orion capsule and a descent stage potentially derived from Blue Origin's cargo lander. Former NASA official Douglas Loverro framed the constraint plainly: in under five years, you cannot invent anything new.

NASA has now issued a request for information from the broader commercial space industry. The race is no longer about which company has the grandest vision — it is about which combination of proven pieces can be assembled fast enough to meet a deadline that has become the measure of American ambition in space.

NASA is hedging its bets on getting astronauts back to the moon. Sean Duffy, the acting administrator of the space agency, announced this week that he would open the bidding for a lunar lander contract to companies beyond SpaceX, citing the rocket manufacturer's falling behind schedule and the political urgency of a deadline that has suddenly become very real.

The pressure is coming from two directions at once. China is aiming to land its own astronauts on the moon by 2030, and President Trump wants an American landing to happen before his second term ends on January 20, 2029—a window of less than three and a half years. That combination has forced NASA's hand. "We're not going to wait for one company," Duffy said on CNBC. "We're going to push this forward and win the second space race against the Chinese." Blue Origin, the space company owned by Jeff Bezos, and Lockheed Martin are among the contractors now being invited to compete.

SpaceX, which won a $2.9 billion contract in 2021 to build the lander for Artemis III, is the incumbent. The company planned to use a version of its Starship rocket—a vehicle as tall as a 17-story building—to carry two astronauts to the lunar surface. But the architecture has proven far more complex than anticipated. Three consecutive test flights failed this year, and even the successful launches since then have been followed by a pause in testing while engineers prepare an improved version. The real bottleneck is a procedure that has never been demonstrated at scale: Starship will need to refuel itself by docking with other Starships in Earth orbit before heading to the moon. SpaceX is also required to land an uncrewed Starship on the moon before any astronauts can go.

Elon Musk responded to the news with characteristic dismissal. "SpaceX is moving like lightning compared to the rest of the space industry," he posted on X, adding that Starship would ultimately handle the entire mission. He also took a shot at Blue Origin, noting that Bezos's company had never delivered a useful payload to orbit, let alone the moon. Blue Origin is developing a lunar lander for NASA, but that $3.4 billion contract is for Artemis V, a mission not scheduled until the 2030s—too late for the Trump administration's timeline.

Jim Bridenstine, who served as NASA administrator during Trump's first term, told Congress in September that the Starship architecture "doesn't make a lot of sense if you're trying to go first to the moon this time to beat China." Even space industry experts who respect SpaceX's technical achievements are increasingly skeptical that the company can solve all the engineering challenges quickly enough to guarantee a safe crewed mission.

Lockheed Martin is proposing a different approach entirely. Rather than developing new technologies, the company is working on a design that would assemble existing hardware—some of it already built and sitting in storage. The lander would be smaller than the current SpaceX and Blue Origin designs, a two-stage spacecraft modeled on the lunar modules used during the Apollo missions, but larger. The crew area would use components from Orion, Lockheed's capsule that will ferry astronauts between Earth and lunar orbit. For the descent stage, one possibility is a variation of Blue Moon Mark 1, the cargo lander Blue Origin is developing.

Rob Chambers, Lockheed's director of human spaceflight strategy, compared the challenge to a scene from "Apollo 13," when engineers had to improvise a fix using whatever was at hand. Douglas Loverro, a former NASA official who has been advocating for this approach, put it more bluntly: "In order to go ahead and build a lander in under five years, you can't invent anything new. Anything you use has to already exist."

NASA is now issuing a request for information from the commercial space industry about how to accelerate the timeline. The question is no longer whether SpaceX can do it alone, but whether any company—or combination of companies—can assemble a working lunar lander from proven pieces fast enough to meet a political deadline that has suddenly become the measure of American space ambition.

We're not going to wait for one company. We're going to push this forward and win the second space race against the Chinese.

Why is NASA suddenly opening this up to other companies now, after giving SpaceX the contract?

Model

Because the timeline shifted. When SpaceX won in 2021, Artemis III was scheduled for mid-2027. That was already ambitious. But now the Trump administration wants a landing by January 2029, and China is breathing down NASA's neck. SpaceX's delays—the failed test flights, the refueling procedure that's never been done at scale—made it clear one company wasn't going to make it.

Inventor

But SpaceX has done remarkable things. Why not just give them more time?

Model

Because time is the one thing NASA doesn't have. And Starship itself is the problem. It's a Mars vehicle, not a moon vehicle. It's enormous, incredibly complex. You need to refuel it in orbit, land it uncrewed first, then land it crewed. That's three separate engineering challenges, each one harder than the last.

Inventor

So Lockheed Martin's approach is to use old parts?

Model

Not old exactly. Proven. They're talking about taking components from Orion, which already exists, and possibly using Blue Origin's cargo lander as a descent stage. It's smaller, simpler, built from hardware that's already been tested. It's the opposite of Starship's philosophy.

Inventor

Can you actually build a crewed spacecraft in three and a half years?

Model

Only if you don't invent anything new. That's what the experts keep saying. You can assemble existing pieces faster than you can develop new ones. But it's still a massive undertaking.

Inventor

What does Musk think about all this?

Model

He thinks NASA is making a mistake. He says Starship will do the whole mission, and that Blue Origin hasn't proven it can do anything. There's some truth to both points, but it doesn't change the fact that SpaceX is behind and NASA needs a backup plan.

Inventor

What happens if neither company makes the 2029 deadline?

Model

Then the Trump administration doesn't get its moon landing before the term ends, and the whole political calculus changes. But that's not NASA's only concern anymore—it's just one of them.
