Last Exit: Space is a new documentary on Discovery+ exploring the possibility of humans colonizing planets beyond Earth, reports Ars Technica.. “Since it is produced and narrated by Werner Herzog and written and directed by his son Rudolph, however, it goes in a different direction than your average space documentary. It’s weird, beautiful, skeptical, and even a bit funny….”
Other times, Werner opts for dryly funny narration of how bleak certain space colonization efforts may turn out. “The reality of life on Mars would be sobering,” he says. “Astronauts would hunker down in radiation-proof bunkers, enjoying drinks of recycled urine….”
For most of the film, Rudolph focuses on two options for where humans might travel, land, and establish space colonies: Mars or an exoplanet in the Alpha Centauri system. Along the way, Last Exit: Space follows a pattern. First, it lists a problem that might make a certain space travel proposition impossible. Then it briefly explains the most promising solution to that problem as developed by modern science and engineering. Finally, it brings the interstellar dream crashing back down to Earth with a grim recounting of why the solution won’t work…. “We know the next planet outside of our solar system is at least 5,000 years away,” Werner tells Ars. “It’s very hard to do that, and [whatever is there is] probably uninhabitable. And we know that on Mars, there’s permanent radiation that will force us underground in little bunkers….”
As Last Exit: Space explores the logistics of a possible 5,000-year journey to Alpha Centauri, the film asks wild questions that touch matters of the human spirit, each with a diverse pool of optimistic and pessimistic answers. Is hibernation feasible? Could a non-hibernating skeleton crew function in a sane way? And how would the human act of copulation play out — both mechanically, in terms of being a reduced-gravity exercise, and genetically, in terms of possible in-breeding if a ship can’t hold at least 40,000 colonists to keep the gene pool diverse…? [Werner Herzog adds] “But as you hear it from Lucian Walkowicz, an astronomer in the film, it’s very clear that we take her position: We shouldn’t behave like locusts who are grazing everything empty here, then move on to the next planet. There’s something not right to shift, to move our population to other planets, and it’s a part of all these ethical questions….
[Space colonization] will fail. It is inevitable. You cannot travel to the next [Alpha Centauri exoplanet] that is 200,000 years away. Period. Good luck….”
The filmmakers make it clear that they admire and appreciate efforts to understand space and our universal neighbors. But in describing “space colonization” as “a dirty word,” Rudolph paraphrases Walkowicz’s film-ending pitch: “There is already a cross-generational spaceship operating right now — and we’re already on it. Earth is a luxuriously furnished, wonderfully self-rejuvenating place, so we’d better treat it well….”
Werner admits that he does have some interest in space travel. “I would love to go out on Mars on a mission… if I had a camera with me,” he says.
Rudolph immediately interrupts: “Yes, but I want to stop my dad. Don’t encourage him on this, please. I want him to stay on Earth.”
