La Administraci\u00f3n Nacional de Aeron\u00e1utica y el Espacio (NASA, por sus siglas en ingl\u00e9s) confirm\u00f3 avances en el desarrollo de SR-1 Freedom, un proyecto que busca demostrar el uso de energ\u00eda nuclear para generar electricidad y alimentar motores capaces de operar durante los viajes interplanetarios. Su lanzamiento est\u00e1 previsto para fines de 2028, con Marte como destino.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"480\" height=\"360\" src=\"https:\/\/aeroespacio.com.ar\/wp-content\/uploads\/2026\/11\/Nasa-rumbo-a-Marte_interior2.jpeg\" alt=\"\" class=\"wp-image-18361\" style=\"width:700px;height:auto\" srcset=\"https:\/\/aeroespacio.com.ar\/wp-content\/uploads\/2026\/11\/Nasa-rumbo-a-Marte_interior2.jpeg 480w, https:\/\/aeroespacio.com.ar\/wp-content\/uploads\/2026\/11\/Nasa-rumbo-a-Marte_interior2-300x225.jpeg 300w\" sizes=\"(max-width: 480px) 100vw, 480px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">La novedad se concentra en uno de los componentes centrales del veh\u00edculo: el m\u00f3dulo de potencia. La agencia anunci\u00f3 acuerdos t\u00e9cnicos que permitir\u00e1n continuar con la construcci\u00f3n del sistema encargado de transformar el calor producido por un reactor de fisi\u00f3n en energ\u00eda el\u00e9ctrica. Este mecanismo representa una alternativa para las misiones que necesitan recorrer grandes distancias y disponer de una fuente de suministro durante los per\u00edodos prolongados.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La empresa Sierra Lobo Inc. tendr\u00e1 a su cargo el desarrollo del equipo de conversi\u00f3n mediante un ciclo Brayton cerrado, un sistema que utiliza el calor para mover una turbina conectada a un generador el\u00e9ctrico. Su funcionamiento se basa en la circulaci\u00f3n de un gas dentro de un circuito. El trabajo se realizar\u00e1 bajo un contrato destinado a tareas de dise\u00f1o, ensayos y operaciones en el Centro de Investigaci\u00f3n Glenn, ubicado en Cleveland, Estados Unidos.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">El reactor ser\u00e1 desarrollado por el Laboratorio Nacional de Idaho, dependiente del Departamento de Energ\u00eda estadounidense. Ambos componentes formar\u00e1n una unidad capaz de abastecer los propulsores el\u00e9ctricos y otros instrumentos de la nave. Por razones de seguridad, el dispositivo de fisi\u00f3n permanecer\u00e1 inactivo hasta que el veh\u00edculo abandone la \u00f3rbita terrestre.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A diferencia de los motores qu\u00edmicos convencionales, que consumen grandes cantidades de combustible en per\u00edodos breves, la propulsi\u00f3n el\u00e9ctrica utiliza energ\u00eda para acelerar part\u00edculas y generar empuje. Aunque la fuerza obtenida es menor, su aplicaci\u00f3n durante los trayectos extensos ofrece ventajas en el consumo de propelente (material que se utiliza para generar empuje) y abre nuevas posibilidades para las futuras expediciones al espacio profundo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">SR-1 Freedom tendr\u00e1 otra tarea durante su viaje. La misi\u00f3n transportar\u00e1 la SkyFall, una carga cient\u00edfica integrada por tres helic\u00f3pteros inspirados en Ingenuity, el peque\u00f1o veh\u00edculo que realiz\u00f3 su primer vuelo controlado sobre Marte el 19 de abril de 2021. Estos equipos buscar\u00e1n recopilar la informaci\u00f3n del terreno, estudiar las posibles zonas de exploraci\u00f3n e identificar los lugares con presencia potencial de agua.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/aeroespacio.com.ar\/wp-content\/uploads\/2026\/11\/NASA-rumbo-a-Marte_interior-1024x576.jpg\" alt=\"\" class=\"wp-image-18362\" srcset=\"https:\/\/aeroespacio.com.ar\/wp-content\/uploads\/2026\/11\/NASA-rumbo-a-Marte_interior-1024x576.jpg 1024w, https:\/\/aeroespacio.com.ar\/wp-content\/uploads\/2026\/11\/NASA-rumbo-a-Marte_interior-300x169.jpg 300w, https:\/\/aeroespacio.com.ar\/wp-content\/uploads\/2026\/11\/NASA-rumbo-a-Marte_interior-768x432.jpg 768w, https:\/\/aeroespacio.com.ar\/wp-content\/uploads\/2026\/11\/NASA-rumbo-a-Marte_interior-1536x864.jpg 1536w, https:\/\/aeroespacio.com.ar\/wp-content\/uploads\/2026\/11\/NASA-rumbo-a-Marte_interior.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">El programa tambi\u00e9n apunta a desarrollar capacidades que puedan aplicarse en las futuras instalaciones sobre la superficie lunar. La experiencia obtenida, con el reactor y sus sistemas de conversi\u00f3n, servir\u00e1 como referencia para los proyectos que necesitan suministro energ\u00e9tico en regiones donde la luz solar resulta insuficiente.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La iniciativa atraviesa una etapa de desarrollo y de pruebas, con desaf\u00edos t\u00e9cnicos y requisitos de seguridad por completar antes del despegue. Si cumple sus objetivos, la demostraci\u00f3n marcar\u00e1 un antecedente para el uso de propulsi\u00f3n el\u00e9ctrica nuclear en misiones interplanetarias y ampliar\u00e1 las herramientas disponibles para explorar otros mundos.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fuente y fotos: NASA<\/p>\n","protected":false},"excerpt":{"rendered":"<p>La exploraci\u00f3n espacial podr\u00eda dar un salto tecnol\u00f3gico con una nueva forma de impulsar naves hacia destinos lejanos.
