¡Vamos a despegar! Qué fascinante es ver y explorar mundos nuevos. El cambiar nuestro ambiente en la Tierra por el ambiente del espacio es muy emocionante. Pero, un ambiente “normal para la Tierra” es muy distinto a un ambiente “normal para el espacio”. El espacio tiene uno de los ambientes más peligrosos que hemos explorado. A medida que cambie el ambiente, también cambiará el cuerpo del astronauta.

Topics: NASA, KSNN
Explorar el espacio es emocionante, pero también puede ser un poco aterrador. Algunas personas opinan que la exploración espacial es demasiado peligrosa para los seres humanos. ¿Deberían los exploradores espaciales ser humanos o robots? ¿Existe una opción correcta?

Alimento. Agua. Aire. Refugio. Todos los seres vivientes tienen estas necesidades básicas. En la Tierra, sabemos donde conseguirlos. En el espacio, estas cosas tienen que ser transportadas desde la Tierra. El astronauta en el espacio necesita 30,60 kilogramos (75,32 libras) de comida, agua, y aire diariamente para mantenerse saludable. Imagínate que una tripulación de 3 astronautas en una misión de un año necesitará 33.000 kilogramos (70.000 libras) de comida, agua, y aire. Sería...

El alimento es una necesidad básica. Tener suficiente alimento mientras viajan siempre ha sido un problema para los exploradores. Además de tener suficiente para comer, los exploradores también necesitan maneras de envasar y almacenar la comida. ¿Qué se puede hacer para asegurarse que la comida no se dañe? Los exploradores de antes secaban comida y la guardaban en lugares frescos. También usaban envases sellados.

Desde la antigüedad, las personas han contemplado el espacio y se han preguntado sobre sus misterios. La inmensidad del espacio nos ha abierto la mente, pero su gran tamaño no nos ha permitido una exploración rápida. Queremos explorar mundos distantes, pero, ¿cómo podemos viajar más rápido para así llegar aun más lejos en el espacio?

El ser humano ha adorado y estudiado la Luna desde hace siglos. Los primitivos Aztecas construyeron una pirámide en Méjico para la “diosa” Luna. Hoy, las personas aún hablan de “el hombre en la Luna”. En la Tierra, las personas siempre han soñado con vida en la Luna, hasta creer que había mares lunares o “maria” (en latín) en la superficie lunar.
