La NASA traerá la nave espacial Starliner de Boeing de vuelta a la Tierra sin los astronautas Butch Wilmore y Suni Williams a bordo, según anunció la agencia el sábado. Este retorno sin tripulación permite a la NASA y a Boeing seguir recopilando datos de pruebas sobre Starliner durante su próximo vuelo de regreso a casa, al tiempo que no implica más riesgo del necesario para su tripulación.

Wilmore y Williams, que viajaron a la Estación Espacial Internacional en junio a bordo de la prueba de vuelo tripulado Boeing de la NASA, han estado ocupados, entre otras actividades, prestando apoyo a la investigación y el mantenimiento de la estación, así como las pruebas de sistema y análisis de datos de Starliner.

“Los vuelos espaciales son arriesgados, incluso en sus momentos más seguros y rutinarios. Un vuelo de prueba, por su propia naturaleza, no es ni seguro ni rutinario. La decisión de que Butch y Suni permanezcan a bordo de la Estación Espacial Internacional y de que la nave Starliner de Boeing regrese a casa sin tripulación es el resultado de nuestro compromiso con la seguridad, la cual es nuestro valor fundamental y nuestra estrella guía”, declaró Bill Nelson, Administrador de la NASA. “Estoy agradecido a los equipos de la NASA y de Boeing por todo su increíble y minucioso trabajo”.

Wilmore y Williams continuarán su trabajo oficialmente como parte de la tripulación de la Expedición 71/72 hasta febrero de 2025. Volverán a casa a bordo de una nave espacial Dragon con otros dos miembros de la tripulación asignados a la misión SpaceX Crew-9 de la agencia. Se espera que Starliner parta de la estación espacial y lleve a cabo una reentrada y un aterrizaje autónomos, seguros y controlados a principios de septiembre.

La NASA y Boeing detectaron fugas de helio y experimentaron problemas con los motores de control de actitud de la nave el 6 de junio, cuando Starliner se aproximaba a la estación espacial. Desde entonces, los equipos de ingeniería han completado una cantidad significativa de trabajo, incluyendo la revisión de una colección de datos, la realización de pruebas de vuelo y tierra, la organización de revisiones independientes con expertos en propulsión de la agencia, y el desarrollo de varios planes de contingencia de retorno. La incertidumbre y la falta de consenso entre los expertos no cumplen los requisitos de seguridad y rendimiento de la agencia para los vuelos espaciales tripulados, lo que ha llevado a la dirección de la NASA a transferir a los astronautas a la misión Crew-9.

“Las decisiones de este tipo nunca son fáciles, pero quiero encomendar a nuestros equipos de la NASA y Boeing por su análisis exhaustivo, discusiones transparentes y enfoque en la seguridad durante la prueba de vuelo tripulado”, dijo Ken Bowersox, administrador asociado de la Dirección de Misiones de Operaciones Espaciales de la NASA. “Hemos aprendido mucho sobre la nave espacial durante su travesía hasta la estación y sus operaciones acopladas. También seguiremos recopilando más datos sobre Starliner durante su regreso sin tripulación, y mejoraremos el sistema para futuros vuelos a la estación espacial.”

Starliner está diseñada para funcionar de manera autónoma y previamente completó dos vuelos sin tripulación. La NASA y Boeing trabajarán conjuntamente para ajustar la planificación del final de la misión y los sistemas de Starliner para prepararse para el regreso no tripulado en las próximas semanas. Starliner debe regresar a la Tierra antes del lanzamiento de la misión Crew-9 para garantizar la disponibilidad de un puerto de atraque en la estación.

“Starliner es una nave espacial muy capaz y, en última instancia, esto se reduce a la necesidad de un mayor nivel de certeza para llevar a cabo un retorno con tripulación”, dijo Steve Stich, gerente del Programa de Tripulación Comercial de la NASA. “Los equipos de la NASA y Boeing han completado una enorme cantidad de pruebas y análisis, y esta prueba de vuelo está proporcionando información crítica sobre el rendimiento de Starliner en el espacio. Nuestros esfuerzos ayudarán a preparar el regreso sin tripulación y beneficiarán en gran medida a futuras acciones correctivas para la nave espacial.”

El Programa de Tripulación Comercial de la NASA exige que las naves espaciales efectúen un vuelo de prueba con tripulación para demostrar que el sistema está preparado para vuelos regulares desde y hacia la estación espacial. Tras el regreso de Starliner, la agencia revisará todos los datos relacionados con la misión para determinar qué medidas adicionales son necesarias para cumplir los requisitos de certificación de la NASA.

La misión SpaceX Crew-9 de la agencia, originalmente programada con cuatro tripulantes, despegará no antes del martes 24 de septiembre. La agencia proveerá más información sobre la tripulación Crew-9 cuando se ultimen los detalles.

La NASA y SpaceX están ahora trabajando en varios aspectos antes del lanzamiento, como reconfigurar los asientos en la nave Crew-9 Dragon y ajustar el manifiesto para transportar carga adicional, efectos personales y trajes espaciales específicos de Dragon para Wilmore y Williams. Además, la NASA y SpaceX utilizarán nuevas instalaciones en el Complejo de Lanzamiento Espacial 40 en la Estación de la Fuerza Espacial de Cabo Cañaveral en Florida para lanzar Crew-9, lo que brindará mayor flexibilidad operativa en torno al lanzamiento planeado de Europa Clipper por parte de la NASA.

La misión Crew-9 será la novena misión de rotación a la estación espacial en el marco del Programa de Tripulación Comercial de la NASA, que colabora con la industria aeroespacial estadounidense para lograr el objetivo de un servicio de transporte seguro, fiable y rentable hacia y desde el puesto orbital mediante cohetes y naves espaciales de fabricación estadounidense que despegan desde territorio de Estados Unidos.

Durante más de dos décadas, la Estación Espacial Internacional ha tenido personas viviendo y trabajando a bordo, impulsando el conocimiento científico y poniendo a prueba nuevas tecnologías, logrando avances en la investigación que no son posibles en la Tierra. La estación es un banco de pruebas fundamental para que la NASA comprenda y supere los retos de los vuelos espaciales de larga duración, así como para expandir las oportunidades comerciales en la órbita terrestre baja. A medida que las empresas comerciales se centran en proporcionar servicios de transporte espacial humano y destinos como parte de una economía robusta de órbita terrestre baja, la campaña Artemis de la NASA está en marcha hacia la Luna, donde la agencia se preparará para la futura exploración con seres humanos de Marte.

      Meet Four NASA Inventors Improving Life on Earth and Beyond
      By NASA

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      When most people think of NASA, they picture rockets, astronauts, and the Moon. But behind the scenes, a group of inventors is quietly rewriting the rules of what’s possible — on Earth, in orbit, and beyond. Their groundbreaking inventions eventually become technology available for industry, helping to shape new products and services that improve life around the globe. For their contributions to NASA technology, we welcome four new inductees into the 2024-2025 NASA Inventors Hall of Fame

      A robot for space and the workplace

      Myron (Ron) Diftler led the team behind Robonaut 2 (R2), a humanoid robot developed with General Motors. The goal was to create a robot that could help humans both in space and on the factory floor. The R2 robot became the first humanoid robot in space aboard the International Space Station, and part of its technology was licensed for use on Earth, leading to a grip-strengthening robotic glove to help humans with strenuous, repetitive tasks. From factories to space exploration, Diftler’s work has real-world impact. 

      Some of the toughest electronic chips on and off Earth

      Technology developed to one day explore the surface of Venus has to be tough enough to survive the planet where temperatures hit 860°F and the atmosphere is akin to battery acid. Philip Neudeck’s silicon carbide integrated circuits don’t just work — they ran for over 60 days in simulated Venus-like conditions. On Earth, these chips can boost efficiency in wireless communication systems, help make drilling for oil safer, and enable more practical electric vehicles. 
      From developing harder chip materials to unlocking new planetary missions, Neudeck is proving that the future of electronics isn’t just about speed — it’s about survival.

      Hydrogen sensors that could go the distance on other worlds

      Gary Hunter helped develop a hydrogen sensor so advanced it’s being considered for a future mission to Titan, Saturn’s icy moon. These and a range of other sensors he’s helped developed have applications that go beyond space exploration, such as factory floors here on Earth.
      With new missions on the horizon and smarter sensors in development, Hunter is still pushing the boundaries of what NASA technology can do. Whether it’s Titan, the surface of Venus, or somewhere we haven’t dreamed of yet, this work could help shape the way to get there. 

      Advanced materials research to make travel safer

      Advanced materials, such as foams and composites, are key to unlocking the next generation of manufacturing. From space exploration to industry, Erik Weiser spent years contributing his expertise to the development of polymers, ceramics, metals, nanomaterials, and more. He is named on more than 20 patents. During this time, he provided his foam expertise to the Space Shuttle Columbia accident investigation, the Shuttle Discovery Return-to-Flight Investigation and numerous teams geared toward improving the safety of the shuttle.  
      Today, Weiser serves as director of the Facilities and Real Estate Division at NASA Headquarters, overseeing the foundation of NASA’s missions. Whether it’s advancing research or optimizing real estate across the agency, he’s helping launch the future, one facility at a time.

      NASA Study Reveals Venus Crust Surprise

      NASA Study Reveals Venus Crust Surprise
      This global view of the surface of Venus is centered at 180 degrees east longitude. Magellan synthetic aperture radar mosaics from the first cycle of Magellan mapping are mapped onto a computer-simulated globe to create this image. Data gaps are filled with Pioneer Venus Orbiter data, or a constant mid-range value. Simulated color is used to enhance small-scale structure. The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. NASA/JPL-Caltech New details about the crust on Venus include some surprises about the geology of Earth’s hotter twin, according to new NASA-funded research that describes movements of the planet’s crust.
      Scientists expected the outermost layer of Venus’ crust would grow thicker and thicker over time given its apparent lack of forces that would drive the crust back into the planet’s interior. But the paper, published in Nature Communications, proposes a crust metamorphism process based on rock density and melting cycles.
      Earth’s rocky crust is made up of massive plates that slowly move, forming folds and faults in a process known as plate tectonics. For example, when two plates collide, the lighter plate slides on top of the denser one, forcing it downward into the layer beneath it, the mantle. This process, known as subduction, helps control the thickness of Earth’s crust. The rocks making up the bottom plate experience changes caused by increasing temperature and pressure as it sinks deeper into the interior of the planet. Those changes are known as metamorphism, which is one cause of volcanic activity.
      In contrast, Venus has a crust that is all one piece, with no evidence for subduction caused by plate tectonics like on Earth, explained Justin Filiberto, deputy chief of NASA’s Astromaterials Research and Exploration Science Division at NASA’s Johnson Space Center in Houston and a co-author on the paper. The paper used modeling to determine that its crust is about 25 miles (40 kilometers) thick on average and at most 40 miles (65 kilometers) thick.
      “That is surprisingly thin, given conditions on the planet,” said Filiberto. “It turns out that, according to our models, as the crust grows thicker, the bottom of it becomes so dense that it either breaks off and becomes part of the mantle or gets hot enough to melt.” So, while Venus has no moving plates, its crust does experience metamorphism. This finding is an important step toward understanding geological processes and evolution of the planet.
      “This breaking off or melting can put water and elements back into the planet’s interior and help drive volcanic activity,” added Filiberto. “This gives us a new model for how material returns to the interior of the planet and another way to make lava and spur volcanic eruptions. It resets the playing field for how the geology, crust, and atmosphere on Venus work together.”
      The next step, he added, is to gather direct data about Venus’ crust to test and refine these models. Several upcoming missions, including NASA’s DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) and VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy) and, in partnership with ESA (European Space Agency), Envision, aim to study the planet’s surface and atmosphere in greater detail. These efforts could help confirm whether processes like metamorphism and recycling are actively shaping the Venusian crust today—and reveal how such activity may be tied to volcanic and atmospheric evolution.
      “We don’t actually know how much volcanic activity is on Venus,” Filiberto said. “We assume there is a lot, and research says there should be, but we’d need more data to know for sure.”
