La Agencia Espacial Europea (ESA) y la Agencia Japonesa de Exploraci\u00f3n Aeroespacial (JAXA) formalizaron su alianza de defensa planetaria con la firma de un memorando de cooperaci\u00f3n y un acuerdo espec\u00edfico para la misi\u00f3n conjunta Ramses. El proyecto enviar\u00e1 una sonda al asteroide Apofis, un objeto de 375 metros de di\u00e1metro que en 2029 pasar\u00e1 extremadamente cerca de la Tierra.<\/p>\n

Durante el anuncio, la ESA reconoci\u00f3 que el entorno espacial es cada vez m\u00e1s complejo y que la cooperaci\u00f3n internacional seguir\u00e1 siendo la piedra angular de su estrategia. Aunque Europa ha trabajado durante a\u00f1os con agencias como la NASA, ahora refuerza su relaci\u00f3n con JAXA para responder con mayor rapidez a amenazas potenciales del espacio exterior<\/a>, impulsados por una \u201cdeterminaci\u00f3n compartida para proteger el planeta\u201d.<\/p>\n

Ramses (Rapid Apophis Mission for Space Safety<\/em>) se convierte en la primera misi\u00f3n de esta alianza orientada a construir un sistema global de protecci\u00f3n planetaria<\/a>. Europa y Jap\u00f3n lanzar\u00e1n una nave de reconocimiento hacia el asteroide, conocido en su momento como el \u201casteroide del caos\u201d, para estudiar c\u00f3mo la gravedad terrestre deforma y altera sus caracter\u00edsticas f\u00edsicas.<\/p>\n

Apophis no chocar\u00e1 con la Tierra, pero es un evento extremadamente raro<\/h2>\n

Apofis<\/a> [nombre oficial (99942) Apophis] encaja en la categor\u00eda de \u201cdestructor de ciudades\u201d. Est\u00e1 compuesto por metales y silicatos, viaja por el sistema solar a una velocidad de entre 25,000 y 30,000 kil\u00f3metros por hora y, por su tama\u00f1o, no se desintegrar\u00eda en la atm\u00f3sfera. Un impacto hipot\u00e9tico liberar\u00eda energ\u00eda equivalente a miles de bombas de Hiroshima y generar\u00eda cr\u00e1teres de varios kil\u00f3metros. Afortunadamente, los cient\u00edficos han descartado cualquier riesgo de colisi\u00f3n durante al menos los pr\u00f3ximos 100 a\u00f1os.<\/p>\n

El 13 de abril de 2029, Apofis pasar\u00e1 a solo 32,000 km de la superficie terrestre, movi\u00e9ndose a unos 45,000 km\/h. Para ilustrar mejor esa cercan\u00eda, la distancia entre la Luna y la Tierra es de 384,400 km. En t\u00e9rminos astron\u00f3micos, rozar\u00e1 el planeta y ser\u00e1 visible a simple vista, aunque sin representar un peligro de consideraci\u00f3n mayor. La ESA calcula que un objeto de este tama\u00f1o pasando tan cerca ocurre apenas una vez cada 5,000 o 10,000 a\u00f1os.<\/p>\n
