NASA says rollout operations at the Kennedy Space Center in Florida began early Friday after being briefly delayed by high winds.
Officials say the trek to the pad is expected to take up to 12 hours.
The mission has been delayed a few times since February due to hydrogen fuel leaks and helium flow problems, but is scheduled to launch April 1.

Real-life space exploration and big-screen science fiction will converge on Friday. As NASA prepares to launch Artemis II, the first crewed mission under the agency’s Artemis program and another step toward sending the first astronauts – Americans – to Mars, the fictional film “Project Hail Mary” premiere will take audiences on a journey into deep space.
The agency provided guidance throughout filming, and also is participating in activities related to the release of the film to connect the agency’s missions, innovations, and discoveries to the public through pop culture.
“Space exploration captures the public’s imagination, and collaboration between science and storytelling brings that sense of discovery to a wider audience,” said Will Boyington, associate administrator for the Office of Communications at NASA Headquarters in Washington. “Inspiring the next generation, whether through rocket launches or sci-fi movies, helps build the talent and support that underpin American leadership in space.”
NASA’s communications personnel provided informal consultation about human spaceflight and science during the making of the movie, and experts from the agency in astrobiology and astrophysics, which are major themes in “Project Hail Mary,” answered questions about these topics during the making of the film. Agency advisors are listed in the credits.
On the movie set, the agency provided an in-person consultation between NASA astronaut Kjell Lindgren and actor Ryan Gosling, who plays an astronaut in the movie. NASA also facilitated brand use guidance and clearance for the agency’s “meatball” and “worm” logos featured in the film.
NASA’s activities related to the movie even reached beyond Earth. In between conducting research and demonstrating new technologies, Expedition 74 crew members living and working aboard the International Space Station, including NASA astronauts Chris Williams, Jessica Meir, and Jack Hathaway, screened “Project Hail Mary” while in orbit.
Artemis II crew members, NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen, who will help make what once was science fiction a reality through their upcoming deep space launch, are expected to have an opportunity to view “Project Hail Mary” while in quarantine. They are preparing to explore more of the Moon for scientific discovery, economic benefits, and to build on our foundation for the first crewed missions to Mars.
Sara Webb (Course Director, Centre for Astrophysics and Supercomputing at Swinburne University of Technology in Australia) wrote a March 18, 2026 essay “Project Hail Mary is packed with hard science. An astrophysicist breaks it down” that focuses on what the filmmakers got right and notes some of the areas where fiction held sway, Note: Links have been removed,
As an astrophysicist, my world revolves around the wonders of space and the mysteries of the universe. This means I can be a tough critic of science fiction books and films that explore these topics.
But when I walked out of a recent preview screening of the film adaptation of Andy Weir’s 2021 science fiction novel Project Hail Mary, I had tears of joy in my eyes. The filmmakers had done justice not just to the original story, but also to the science at the heart of it.
The story revolves around Ryland Grace, played by Ryan Gosling, who awakes from a coma with no memory and no idea why he’s on a space ship 11.9 light years away from Earth. As his memories slowly start to return, the truth becomes clear. The Sun is dying, and he is our only saving grace.
…
A dying sun
In Project Hail Mary the Sun is dying due to an alien organism that has spread around our part of the Milky Way.
Firstly, could an organism spread from one solar system to another? According to some scientists, yes. It’s a theory called panspermia.
We have no hard evidence to prove it right now. But the theory isn’t completely wild. We know material from solar systems can be transported great distances – we ourselves have witnessed as least three interstellar visitors enter and fly through our Solar System.
If life forms could survive the harshness of space and live on such rocky bodies, it’s possible this is how life could spread. But that life would likely be basic organisms.
As for the organism at the centre of this movie, astrophage, its mechanics and behaviour sit rightly in the wonderful world of science fiction [emphasis mine].
The size of space
The idea of humans travelling between stars feels like an almost impossible challenge.
In our galaxy alone there are more than 400 billion stars, but only roughly 100 of them are within 20 light years of Earth.
Project Hail Mary focuses it’s attention on one of those systems, known as Tau Ceti, sitting 11.9 light years away.
If we were to travel to this star with the fastest spacecraft humans have ever flown in, the Apollo 10 module, travelling at more than 39,900 kilometres per hour, it would take us 320,000 years. In a story where the Sun is dying now, there is no time for that. So how does Project Hail Mary overcome this problem?
Enter special relativity.
Special relativity is one of the most paradigm-shifting theories of modern history. Developed by Albert Einstein in 1905, it equated mass and energy as one and the same. It best known by the famous E = mc2 formula.
What Einstein was able to work our mathematically, and we’ve later proved observationally, is that the closer to the speed of light something travels, the slower the time it experiences in its reference frame.
It’s called a Lorentz transformation – and it allows us to determine the time experienced in a reference frame different to our own, say travelling close to the speed of light.
The movie doesn’t give a full physics lesson on this, but rather uses visual cues, including correct mathematics worked out by Grace on a whiteboard to demonstrate this time change.
What Grace determines is that he’s only been in a coma for four years due to the effects of time dilation on a ship travelling that fast. Which is scientifically spot on.
We have to talk about the aliens

As you can see Webb’s March 18, 2026 essay is engaging and accessible to those of us who don’t have physics degrees.
Both Science magazine and Nature magazine have Project Hail Mary articles.Perri Thaler’s March 19, 2026 article for Science magazine presents a Q&A (question and answer) with Wendy Freedman, University of Chicago astronomer who studies the evolution of the universe,
…
Q: How scientifically accurate is the movie?
A: What really struck me was how well it represented how science is done and how a scientist approaches problems. You have a leading actor, Ryan Gosling, playing an actual scientist, not an evil man with a white lab coat. He’s a human being. He’s thoughtful and he’s confronted with real challenges that he has to solve. He collaborates, and science is a very collaborative enterprise, so I really like the way science was portrayed in the movie. Lots of speculative ideas, but also lots of real science and a real approach to science.
Q: If you were Ryland Grace, would you approach the problem differently?
A: He approaches things very thoughtfully, methodically. Here’s an idea, a hypothesis, and let’s test it. If it doesn’t work out, well, what went wrong? What else can we do? In terms of basic approach, I’d be very similar, I think.
Q: Was there a specific concept that you noticed in a scene that made you nerd out because the filmmakers got it right or got it wrong?
A: I love that relativity was part of the plot, and that the equipment he had for trying to understand the basis of the life form was a very realistic portrayal of science. The microbiology, chemistry, physics, and astrophysics were all great.
Q: How do you feel about the idea of non–water-based life?

I was able to access Thaler’s March 19, 2026 article but it was one of those ‘you have x articles for free’ deals.
Alexandra Witze’s March 19, 2026 article for Nature magazine includes insights from a scientist who consulted on the film, Note: Links have been removed,
The film Project Hail Mary — which opens widely on Friday — has one of the best opening scenes on the silver screen in recent years. A man wakes up, disoriented and with a fuzzy memory, next to two dead bodies. We find out that he’s a scientist-turned-astronaut on a spaceship headed for a star beyond our Solar System, and those dead bodies are his crewmates. He’s all alone, and it’s now up to him to save life on Earth.
The gripping sci-fi plot comes from the mind of Andy Weir, the author of the 2021 book [Project Hail Mary] of the same name. Weir has become known for stories like this, in which quick-witted loners have to ‘science’ the heck out of situations to save the day. He made his career with the 2011 book The Martian, in which protagonist Mark Watney (played by Matt Damon in the film version) survives being stranded on Mars by, among other things, learning to grow potatoes in the red planet’s soil.
Weir famously steeps his books in science, going so far as to do calculations on orbital mechanics and stellar astrophysics to ensure that the stories are as realistic as they can be while still being fiction. That all-out nerdery has earned him many fans, says Andy Howell, an astronomer at the University of California, Santa Barbara, who advised Weir on the science in Project Hail Mary. “I’ve talked to so many scientists who are like, ‘this is great’”, Howell says, but also engineers, physics students and others.
…
Realistic fiction
Without giving away too much of the plot, Project Hail Mary is about a man, Ryland Grace (played by Ryan Gosling), who embarks on interstellar travel to understand why the Sun is dying. Like Watney in The Martian, he has to summon knowledge from a raft of different types of science — molecular biology, neutrino physics and more — to solve his crisis.
“It’s a great blend of some ideas that have been around, but a fresh take on them — and then some completely new ideas,” says Howell, who also runs a YouTube channel called Science vs. Cinema.
…
Take astrophage, a fictional space microorganism that underpins much of the plot. Weir conceived of it as ‘black matter’ that can absorb huge amounts of stellar radiation and then re-emit the energy to enable interstellar travel. Astrophage doesn’t exist in our world, but Weir made sure it had biology and chemistry that could exist in the Galaxy.
In the film, Grace grapples with the nature of astrophage, which is devouring the Sun, and how it does or doesn’t meet scientists’ notions of extraterrestrial life. It’s reminiscent of debates over how to recognize the signatures of life beyond Earth — for instance, gases in planets’ atmospheres that might have been generated by living organisms.
Building worlds
How astronomers in the film (and book) discover that the Sun is dimming is also grounded in reality. On Howell’s advice, Project Hail Mary gives a shout-out to the amateur astronomers who regularly monitor fluctuations in stars’ brightnesses. In 2019, astronomy enthusiasts spotted the mysterious dimming of the red-giant star Betelgeuse; fortunately, it turned out to be caused by the star belching dust, rather than an astrophage attack.
