Here are the actual physics, here are the engineering problems we'd need to solve
En un auditorio universitario de Mendoza, un científico de la NASA que ha pasado décadas explorando los límites del viaje interestelar llevará esa conversación —habitualmente reservada para laboratorios y congresos especializados— al alcance del público general. Les Johnson, cuya carrera une el rigor de la propulsión espacial con la imaginación de la ciencia ficción, invita a una ciudad provincial a preguntarse si las estrellas pertenecen al futuro o simplemente a la fantasía. Es uno de esos momentos en que el conocimiento abandona sus recintos habituales y se ofrece, sin condiciones, a quienes tengan curiosidad.
- Un científico de la NASA con décadas de trabajo en propulsión espacial avanzada llega a Mendoza el 9 de junio para hablar de lo que la física realmente permite —no de lo que la ciencia ficción imagina.
- Johnson encarna una rareza: es a la vez investigador técnico y escritor de ciencia ficción, consultor de Hollywood y divulgador para Discovery y National Geographic, alguien que traduce ecuaciones en historias sin perder precisión.
- La conferencia 'Opciones Realistas para el Viaje Interestelar' se celebra en el Auditorio de la Universidad Regional de Tupungato a las 18:30, abierta a cualquier persona curiosa, sin requisitos académicos.
- Al final habrá espacio para preguntas, convirtiendo el evento en un diálogo real entre un experto mundial y una audiencia que pocas veces tiene acceso directo a este nivel de conocimiento.
- Para Mendoza, recibir a alguien de la trayectoria de Johnson representa una oportunidad infrecuente: que una ciudad no metropolitana se convierta, por una noche, en escenario de una conversación sobre el destino espacial de la humanidad.
Les Johnson, científico de la NASA especializado en propulsión espacial y conceptos avanzados, visitará Mendoza el martes 9 de junio para ofrecer una conferencia pública titulada 'Opciones Realistas para el Viaje Interestelar'. El evento tendrá lugar a las 18:30 en el Auditorio de la Universidad Regional de Tupungato, en la intersección de Alem y Dorrego, en el barrio Villa Bastías.
Johnson no es solo un investigador: es también autor de libros que van desde tratados técnicos hasta narrativa de ciencia ficción, y miembro de la Science Fiction and Fantasy Writers Association of America. Esa doble pertenencia —al mundo de la física y al de la imaginación— lo ha convertido en un comunicador excepcional. Fue consultor técnico de la película Lost in Space y ha aparecido en documentales de Discovery Channel y National Geographic, explicando conceptos complejos a audiencias amplias sin sacrificar el rigor.
La conferencia está abierta al público general. No se trata de un seminario cerrado para especialistas, sino de una invitación a cualquier persona que se haya preguntado alguna vez si viajar a otras estrellas es ciencia ficción o un problema de ingeniería con solución posible. Al terminar su exposición, Johnson responderá preguntas, abriendo un espacio de intercambio directo.
Que un científico de su calibre llegue a una ciudad provincial es, en sí mismo, un acontecimiento. Mendoza tendrá por una noche acceso privilegiado a alguien que piensa el futuro interestelar de la humanidad no como fantasía, sino como desafío técnico concreto.
Les Johnson is coming to Mendoza. The NASA scientist, who has spent decades thinking about how humans might one day reach beyond our solar system, will spend an evening in June talking about the practical pathways to interstellar travel—the kind of conversation that happens rarely outside university halls and research institutes.
Johnson carries credentials that span both the rigorous and the imaginative. At NASA, he has built a career in space propulsion and advanced concepts. But he is also a writer—the author of multiple books that range from technical treatises to science fiction narratives. He holds membership in the Science Fiction and Fantasy Writers Association of America, the kind of dual citizenship that allows him to speak fluently in both the language of physics and the language of possibility.
That hybrid expertise has made him valuable to the entertainment industry as well. He served as a technical consultant on the film Lost in Space, ensuring that the speculative elements held some anchor to actual science. He has appeared on documentaries for Discovery Channel and National Geographic, translating complex concepts about space exploration into forms that general audiences can grasp and engage with.
On Tuesday, June 9th, at 6:30 in the evening, Johnson will arrive at the Tupungato Regional University Auditorium—located at the intersection of Alem and Dorrego streets in the Aero Club neighborhood of Villa Bastías—to share what he has learned. The lecture carries the title "Realistic Options for Interstellar Travel," a framing that suggests Johnson will not indulge in pure speculation but will instead ground the conversation in what physics and engineering actually permit.
The event is open to the general public. This is not a closed seminar for specialists. Anyone curious about humanity's prospects for reaching other star systems, anyone who has wondered whether interstellar travel belongs to science fiction or to the near future, is invited to attend. After Johnson finishes his formal remarks, there will be time for questions—a chance for the audience to push back, to ask the questions that have been forming in their minds, to test the boundaries of what he believes is possible.
It is the kind of event that rarely happens in a provincial city. A scientist of Johnson's standing, with his particular combination of technical authority and communicative skill, does not often make the journey to smaller urban centers. For Mendoza, it represents an opportunity to engage directly with someone who thinks seriously about humanity's future in space—not as fantasy, but as engineering problem, as physics challenge, as something that might actually happen.

Johnson will share his experiences and vision on interstellar travel with Mendoza audiences— Event description
La Conversación del Hearth Otra perspectiva de la historia
Why does a NASA scientist who could be anywhere choose to come to Mendoza and talk about interstellar travel?
Because the conversation matters everywhere, not just in Silicon Valley or Washington. People here wonder about the same things—what's possible, what's next, how far we can actually go.
But interstellar travel seems impossibly far away. Why frame it as "realistic options"?
That's the whole point. Johnson isn't selling fantasy. He's saying: here are the actual physics, here are the engineering problems we'd need to solve, here's what's theoretically possible within the laws of nature. That's more interesting than pure speculation.
He's also a science fiction writer. Does that undermine his credibility as a scientist?
No—it sharpens it. He understands both what's real and what's imaginable. He can see the gap between them clearly. That's why filmmakers trust him as a technical consultant. He knows how to make the speculative grounded.
What would someone in the audience actually take away from an evening like this?
A clearer sense of what's actually being researched right now, what the obstacles are, what timescales we're talking about. And maybe permission to think seriously about space as something humanity might actually do, not just dream about.
Is this the kind of event that changes how a city thinks about itself?
Not overnight. But it plants something. It says: we're the kind of place where serious people come to talk about serious futures. That matters.
