Impressions (No Spoilers)

The film Hail Mary leaves a very positive impression overall. If someone likes science fiction, they might really enjoy this movie. This is exactly the kind of film that not only shows beautiful images of space but also keeps you on the edge of your seat for almost the entire runtime. The plot constantly throws in new twists, and the characters’ decisions keep you hooked on the story.

Ryan’s acting deserves special mention. Everything is portrayed very naturally: the characters feel like real people, not just vehicles for the plot. This makes it easier to believe both the story itself and the characters’ emotional reactions. Another important plus is the attention to detail. It was particularly pleasing that the film accurately depicts one of the basic principles of space: there is no sound in outer space. For a sci-fi film, this might seem like a minor detail, but it is precisely these details that greatly enhance the film’s believability.

Poster for the film Project Hail Mary

Hail Mary is a fantastic film that works on several levels: as a suspenseful adventure, as a story of survival, and as a film that strives to respect scientific logic. That’s exactly why the film resonates not only emotionally but also intellectually.

It is also interesting to compare it to the film U Are the Universe. One gets the sense that these films resonate with each other in some ways: both use space not merely as a backdrop, but as a realm of solitude, connection, hope, and human vulnerability. But while U Are the Universe is a more intimate, lyrical, and existential story, Hail Mary is a larger-scale, technically sophisticated, and plot-driven science fiction film. And there is an interesting point here: if the creators of U Are the Universe had delayed the film’s release just a little longer, and it had come out after Hail Mary, some viewers would surely have accused them of plagiarism. In reality, that would have been unfair: the Ukrainian film had already been released earlier as an independent work. And even Andy Weir’s book Hail Mary was not published until 2021.

Technical Analysis with Spoilers

From an engineering perspective, the film is particularly interesting because it invites analysis rather than just watching. And for the most part, this is a plus: if, after watching it, there is a desire to discuss fuel, the atmosphere, materials, and manufacturing technologies, then the science fiction has done its job.

The first – and perhaps the most controversial – point concerns the logistics of the protagonist’s return journey. This is the film’s weakest point. Even with full tanks – roughly two million liters of astrofuel – the return trip would take about four years, so questions about the mission’s supplies arise at this stage. Based on the plot’s logic, there was enough food for about two years, and after subsequent events, the available fuel supply is further reduced by two sections. As a result, the return mission begins to look less like an engineering-driven scenario devised by the protagonist and more like a very optimistic hope for a miracle. This does not ruin the film entirely, but it is here that the tension between the drama and the real-world logistics of interstellar flight is felt most acutely.

The second point of contention is taumeba and xenonite. Conceptually, this is a very striking idea, but it raises the most questions precisely from the perspective of the world’s internal physics. If xenonite is presented as a reliable structural and airtight material, then taumeba’s ability to pass through it requires a very serious explanation. It is not enough here to say that this is unusual biology; there needs to be a clear mechanism that explains exactly how it happens, under what conditions, and due to which properties of the material and the organism. That is why this particular plot point raises the most scientific doubts for me. It works as a dramatic twist, but as a hard sci-fi premise, it looks noticeably weaker than many of the film’s other ideas.

That said, the atmosphere on the ship and the final dome actually struck as quite plausible. Here, the film, on the contrary, enters the realm of logical engineering solutions. When it comes to a pressurized environment for humans, the basic principles are quite clear: controlling pressure, gas composition, temperature, humidity, removing carbon dioxide, and maintaining a safe environment. In this sense, the dome in the finale can be seen as a development of the same ideas used in space life support systems (e.g., the ISS), only adapted to a different technological platform. Therefore, this aspect should be defended rather than criticized.

The idea of highly advanced 3D printing on an alien spacecraft struck as particularly compelling. The way tunnels, structures, and various objects are formed is an extremely advanced form of 3D printing or programmable manufacturing. And this is precisely one of those ideas that, in science fiction, does not seem like magic but rather a logical progression of real-world technologies. If a civilization is capable of building complex structures directly within the required environment, with high precision, using readily available materials, and tailored to a specific task, then this seems very realistic for a highly advanced engineering culture.

The same applies to the translator. The film presents him not as a magic button, but as the result of a gradual search for patterns, the comparison of signals, learning, and the development of a common language. It is precisely this approach that makes the idea convincing. This is no longer a fairy-tale “universal understanding of aliens,” but an engineering problem of communication that is solved step by step. And within the realm of science fiction, it makes perfect sense.

Ultimately, what makes Hail Mary great for me is that it can be viewed in two different ways. The first is simply a powerful, intense, and emotional science fiction film. The second is a film that invites technical analysis. And even its controversial moments are not so much a drawback as a reason for discussion. Because the most interesting sci-fi films are not the ones that leave no questions, but the ones that make viewers want to debate trajectories, materials, atmosphere, biology, and technology.

What differences and nuances did you notice? Let’s discuss them in the comments.

The Applied Physics Laboratory (APL) at Johns Hopkins University has officially begun assembling one of the most unusual spacecraft in the history of space exploration. The Dragonfly unmanned helicopter, whose design resembles the legendary ornithopters from Frank Herbert’s Dune universe, is preparing for a mission to Titan.

Dragonfly is a drone-based mission under NASA’s New Frontiers program designed to utilize Titan’s unique environment to collect material samples and determine the composition of the surface under various geological conditions.

Although it is not the barren Arakis, Saturn’s largest moon will greet the explorer with vast expanses of sand dunes. And while the chances of encountering a sandworm there are practically nonexistent, the scientific potential of this mission is truly impressive.

Dragonfly isn’t just a drone. It’s a fully-fledged autonomous robot about the size of a small car. Unlike rovers, which take years to cover just a few dozen kilometers, the flying probe will be able to “hop” vast distances, exploring various regions of Titan in a single flight.

Once it reaches the moon’s surface in 2034, the spacecraft will conduct a comprehensive analysis, ranging from studying the composition of the atmosphere to taking seismic measurements. The chemical composition of the surface is of particular interest. Beneath Titan’s thick layer of ice lies a global ocean of salty water, making this world one of the most promising places to search for extraterrestrial life.

A slow and cold world

Titan is truly an amazing place. It is the only moon in the Solar System with a dense atmosphere. The air there is four times denser than Earth’s, and gravity is seven times weaker. This creates some amazing conditions: if you were there in the rain, the methane droplets would fall extremely slowly, as if in slow motion.

However, waiting for such a downpour is no easy task, since centuries can pass between precipitation events on Titan. Such a stable, albeit cold, chemical environment is the ideal place for the formation of organic compounds. Scientists consider Titan to be “Earth in the freezer”—it looks just like our planet before the first living organisms appeared on it.

A costly mission

Exploring Titan is no cheap project. The total cost of the mission is estimated at $3 billion. Previous attempts to peer beneath the moon’s thick, foggy veil have been extremely limited: in 2005, the Huygens probe lasted only a few hours on the surface due to a lack of power.

Since Dragonfly is designed for long-term operation, solar power is not an option — there is too little light penetrating Titan’s thick haze. Therefore, Dragonfly will be powered by nuclear energy. The spacecraft will be equipped with a multi-mission radioisotope thermoelectric generator (MMRTG). Fuel rods containing plutonium will generate heat, which will be converted into electricity to power electronics, servos, and scientific instruments. This technology has already proven itself on the Curiosity and Perseverance rovers.

Beginning of the journey

The mission is scheduled to be launched in 2028 using a SpaceX Falcon Heavy rocket. After launch, the spacecraft will spend six long years traveling through the Solar System. When Dragonfly finally spreads its rotors over the lakes and rivers of liquid ethane in 2034, humanity will get its clearest view of this mysterious world yet.

In the meantime, engineers continue to assemble this nuclear-powered ornithopter, keeping in mind the golden rule for travelers across the dunes: “The spice must flow,” and science must move forward.

We previously reported that the Dragonfly underwent a critical design review prior to the start of the assembly phase.
