DEEP-IN, also known as Directed Energy Propulsion for Interstellar Exploration, is a spaceflight propulsion concept that uses photonic laser propulsion with beamed power to propel a spacecraft in deep space. The concept was originally conceived by Professor Philip Lubin of the University of California Santa Barbara's Physics Department. Lubin is developing it under the NASA Innovative Advanced Concepts Program. DEEP-IN is notable as the first NASA-backed photonic laser propulsion concept. It is heavily derived from DE-STAR, a planetary defense satellite concept previously developed by Lubin, in which he proposes using directed energy from lasers to vaporize or knock off course destructive asteroids headed for Earth.

  • DEEP-IN, also known as Directed Energy Propulsion for Interstellar Exploration, is a spaceflight propulsion concept that uses photonic laser propulsion with beamed power to propel a spacecraft in deep space. The concept was originally conceived by Professor Philip Lubin of the University of California Santa Barbara's Physics Department. Lubin is developing it under the NASA Innovative Advanced Concepts Program. DEEP-IN is notable as the first NASA-backed photonic laser propulsion concept. It is heavily derived from DE-STAR, a planetary defense satellite concept previously developed by Lubin, in which he proposes using directed energy from lasers to vaporize or knock off course destructive asteroids headed for Earth. The system is scalable and modular, so that gradually larger objects can be propelled into space at relativistic speeds (speeds that are a significant fraction of the speed of light) with increasingly powerful lasers. Currently, research models suggest that using this technology, a satellite massing 100 kilograms (220 lb) could reach Mars in 3 days, a significantly shorter time than the current transit time. Additionally, a more massive crewed spacecraft, such as the Orion spacecraft, could reach Mars in one month, compared to the traditional requirement of at least 5 months. However, News Ledge notes that this short transfer time would require a second array of lasers already existing on Mars to slow vehicles down for Mars orbital insertion. (en)

Se deriva en gran medida de DE-STAR, un concepto de satélite de defensa planetaria desarrollado anteriormente por Lubin, en el que propone utilizar la energía dirigida de los láseres para vaporizar o desviar de su curso a los asteroides destructivos que se dirigen a la Tierra.​​​​ El sistema es escalable y modular, de modo que se pueden propulsar al espacio objetos gradualmente mayores a velocidades relativistas (velocidades que son una fracción significativa de la velocidad de la luz) con láseres cada vez más potentes.​ Actualmente, los modelos de investigación sugieren que utilizando esta tecnología, un satélite con una masa de 100 kilogramos (220 libras) podría llegar a Marte en 3 días, un tiempo significativamente más corto que el tiempo de tránsito actual. Además, una nave espacial más masiva con tripulación, como la nave Orión, podría llegar a Marte en un mes, frente al requisito tradicional de al menos 5 meses.​ Sin embargo, News Ledge señala que este corto tiempo de traslado requeriría un segundo conjunto de láseres ya existentes en Marte para frenar los vehículos para la inserción orbital en Marte.​ (es)
