When astronauts land on the Moon, it will be an achievement for all humanity
En los confines de la órbita terrestre, China ha cruzado un nuevo umbral: la misión Shenzhou-23 lleva a tres astronautas a la estación Tiangong, donde uno de ellos permanecerá durante un año completo, el período más largo en la historia espacial tripulada del país. Este hito no es un gesto aislado, sino un eslabón deliberado en una cadena que apunta a la Luna antes de 2030, en un momento en que la humanidad vuelve a mirar hacia el cielo con ambiciones renovadas y rivalidades apenas disimuladas. La pregunta que subyace no es solo técnica —cómo resiste el cuerpo humano el vacío prolongado— sino también filosófica: ¿a quién pertenece el cosmos, y qué significa conquistarlo juntos?
- China lanzó la Shenzhou-23 desde Jiuquan con tres astronautas a bordo, logrando un acoplamiento exitoso con la estación Tiangong en apenas tres horas y media.
- Por primera vez en la historia espacial china, un tripulante permanecerá en órbita durante doce meses continuos, sometiendo cuerpo y mente a condiciones que ningún astronauta del programa había enfrentado antes.
- La misión incluye a Li Jiaying, exsuperintendente de la policía de Hong Kong y primera astronauta de esa ciudad en participar en una misión espacial china, cuyas primeras palabras desde la órbita fueron: 'Me siento bien'.
- Los datos recogidos sobre pérdida ósea, atrofia muscular y fatiga psicológica serán decisivos para los vuelos lunares que China planea realizar antes de 2030, en paralelo al programa Artemis de la NASA.
- Mientras Pekín desarrolla la nave Mengzhou, el cohete Larga Marcha-10 y el módulo de aterrizaje Lanyue, la carrera espacial del siglo XXI avanza a toda velocidad, aunque uno de sus protagonistas prefiera no llamarla así.
La Shenzhou-23 despegó del Centro Espacial de Jiuquan llevando a tres astronautas hacia la estación Tiangong: el comandante Zhu Yangzhu, el piloto Zhang Zhiyuan y Li Jiaying, exsuperintendente de la policía de Hong Kong, quien se convierte en la primera persona de esa ciudad en participar en una misión espacial china. Tras tres horas y media de vuelo, la nave se acopló con éxito. Desde la órbita, Li pronunció palabras sencillas: «Me siento bien».
El propósito central de la misión es científico y estratégico a la vez. Uno de los tres tripulantes —aún por determinar mediante evaluaciones médicas y psicológicas durante el vuelo— permanecerá en órbita durante un año completo, mientras los otros dos regresarán a los seis meses. Es la estancia orbital continua más larga de la historia del programa espacial chino. El astrofísico Richard de Grijs advierte sobre los costos físicos: pérdida de densidad ósea, atrofia muscular, alteraciones del sueño y fatiga psicológica. Comprender cómo el cuerpo humano resiste esas condiciones es indispensable para los viajes más largos que se avecinan.
Esta misión forma parte de una arquitectura mayor. China tiene como objetivo aterrizar astronautas en la Luna antes de 2030 y trabaja simultáneamente en la nave Mengzhou —sucesora de la Shenzhou para vuelos lunares—, en la misión Chang'e-7 al polo sur lunar, y en las pruebas del cohete Larga Marcha-10 y el módulo de aterrizaje Lanyue. Antes de 2035, planea construir el primer módulo de una Estación Internacional de Investigación Lunar.
El contexto es inevitable: Estados Unidos, a través del programa Artemis con NASA y SpaceX, apunta a una misión lunar tripulada en 2028. El ingeniero chino Zhou Yaqiang insiste en que su país no compite con nadie, y que cuando los astronautas pisen la Luna, será un logro para toda la humanidad. Sea diplomacia o convicción, los calendarios paralelos y el ritmo acelerado de ambas potencias sugieren una carrera que se corre aunque ninguno quiera nombrarla.
China's Shenzhou-23 lifted off from the Jiuquan Space Center on a mission that marks a significant threshold for the country's space program: one of its three crew members will remain aboard the Tiangong station for a full year, the longest continuous orbital stay in Chinese spaceflight history. The spacecraft docked successfully after three and a half hours of flight, carrying commander Zhu Yangzhu, pilot Zhang Zhiyuan, and Li Jiaying, a former Hong Kong police superintendent who becomes the first astronaut from Hong Kong to participate in a Chinese space mission. When Li's voice came through from orbit, the words were simple: "I feel well."
The mission serves a precise scientific purpose. By keeping one crew member in space for twelve months while the others return after approximately six months, China aims to understand how the human body and mind respond to extended weightlessness and radiation exposure. These findings will be essential for the longer journeys ahead—to the Moon and potentially beyond. Richard de Grijs, an astrophysicist, outlined the physical toll such a mission demands: bone density loss, muscle atrophy, sleep disruption, and psychological fatigue. A year in microgravity pushes both astronauts and equipment into operational territory unlike anything the program has attempted before. Which crew member will stay for the full duration remains undecided; medical and psychological evaluations during the mission will determine the selection.
Shenzhou-23 is not an isolated achievement but rather a deliberate step within a larger architecture. China has set a target of landing humans on the Moon before 2030, and this mission gathers critical data for that objective. The country is simultaneously developing the Mengzhou spacecraft, designed to eventually replace Shenzhou for lunar flights. It is also preparing the Chang'e-7 mission to the Moon's south pole and conducting tests of the Long March-10 rocket and the Lanyue landing module—both essential components for crewed lunar expeditions. Before 2035, China intends to construct the first module of an International Lunar Research Station.
The timing places this launch squarely within a renewed global space competition. The United States, through NASA and private partners including SpaceX, is pursuing its own lunar return through the Artemis program, with a target of 2028 for a crewed landing. Yet Chinese officials frame their efforts differently. Zhou Yaqiang, a senior engineer at China's space agency, stated that the country does not compete with other nations in space—that when astronauts eventually set foot on the Moon, it will be an achievement for all humanity. Whether that framing reflects genuine intent or diplomatic language, the parallel timelines and accelerating pace suggest a race that both sides are running, even if one side declines to call it that.

La Conversación del Hearth Otra perspectiva de la historia
Why does keeping one person in orbit for a full year matter so much? Isn't China already sending people to space?
They are, but not for this long. A year is fundamentally different from six months or three months. Your bones start to weaken in ways that take months to become critical. Your mind needs to adapt to isolation in a way that shorter missions don't fully test. They need that data before they ask people to spend months traveling to the Moon.
And the fact that it's someone from Hong Kong—is that symbolic, or does it matter operationally?
Both. Operationally, you want diverse crews, different physiologies, different psychological profiles. But yes, it's also a statement. Hong Kong has its own space history, its own identity. Including Li Jiaying says something about how China sees its program expanding beyond the mainland.
The Americans say they'll be on the Moon by 2028. China says 2030. Who wins?
That assumes the first one there wins. But what matters more is who stays, who builds, who can sustain a presence. A landing is a moment. A station is a foothold.
What's the biggest risk in keeping someone up there for a year?
Psychologically, it might be harder than the physical toll. You're watching Earth rotate below you for 365 days. You can't walk outside. You can't leave. Some people thrive in that. Others break.
Has anyone else done this?
Not for a full year continuously. The Russians and Americans have done long missions—months at a time on Mir and the International Space Station. But a year is still rare, still unproven for the Chinese program specifically.
