Aún nadie había logrado alzarse por encima del espacio exterior. En plena Guerra Fría, en que Estados Unidos y la Unión Soviética competían por triunfar, fue la segunda quien logró llevar a Yuri Gagarin al espacio exterior, convirtiéndolo así en la primera persona de la historia de la humanidad en contemplar la Tierra desde el espacio.
El gran suceso ocurrió un 12 de abril de 1961 y, aunque fue un viaje muy distinto a los que conocemos hoy, marcó un hito en la historia de la exploración espacial.
¿Cómo fue el primer viaje al espacio exterior?
En condiciones rotundamente distintas a los viajes espaciales de la actualidad, el primer vuelo tripulado hacia el espacio exterior tuvo lugar el 12 de abril de 1961. Partió a las 6:07 desde Kazajistán (en ese entonces, Unión Soviética), duró 1 hora y 48 minutos y aterrizó de manera segura en territorio ruso a las 7:55.
(Podría interesarte: Polémico: Estados Unidos hizo la primera prueba al aire libre para desviar los rayos del Sol y combatir el cambio climático)
La nave espacial en que viajaba Gagarin fue llamada Vostok-1, se trataba de una cápsula esférica pequeña diseñada para un solo tripulante. La Vostok-1 completó una órbita alrededor de la Tierra a una altitud de entre 301 y 325 kilómetros.
Gracias a este sencillo pero único viaje, se abrió una era de exploración espacial en la que hoy participan indirectamente más de 70 países. En parte gracias a este hito, actualmente la humanidad se sirve de los satélites que, entre muchas otras funciones, logran predecir desastres climáticos y realizar actividades de conservación y restauración de la naturaleza a través de imágenes satelitales.
