Una misi\u00f3n espacial puede durar lo que sea, desde una semana hasta seis meses, pero, \u00bfqu\u00e9 sucede cuando la tripulaci\u00f3n vuelve a la Tierra? En unas pocas horas, pasan de un entorno de ingravidez a la gravedad normal. En lugar de vivir donde todo tiende a flotar, vuelven a un planeta en el que todo movimiento requiere esfuerzo.<\/p>\n<\/div>\n

Readaptarse a la gravedad de la Tierra es dif\u00edcil, porque los m\u00fasculos y huesos se han debilitado y el coraz\u00f3n debe trabajar mucho m\u00e1s para bombear sangre alrededor del cuerpo. Los astronautas que vuelven en una nave especial Soyuz necesitan la ayuda de personal de rescate ruso y son trasladados a helic\u00f3pteros que los esperan en la primera parte de su jornada de regreso a casa.<\/p>\n

Even those who fly back in the Shuttle often feel lightheaded. Some may faint. They also have trouble standing up, walking, turning corners and keeping a sense of balance. If they close their eyes, they are likely to fall over. Even sleeping can be difficult. Some cosmonauts have reported that, months after their flight, they sometimes let go of a cup or other object in mid-air – and are shocked when it crashes to the floor! It can take three to four days to readjust after short flights, but four weeks or more after a six-month stay on the International Space Station.<\/p>\n

Hay otros efectos colaterales que tardan mucho m\u00e1s en desaparecer. La disminuci\u00f3n de la densidad \u00f3sea aumenta el riesgo de sufrir la ruptura de huesos. Con los m\u00fasculos debilitados es m\u00e1s dif\u00edcil levantar incluso objetos ligeros o llevar a cabo las actividades cotidianas. Sin embargo, es dif\u00edcil resistirse a las maravillas de los viajes espaciales. Ocho personas han volado al menos seis veces al espacio. El ruso Valeri Polyakov pas\u00f3 240 d\u00edas en \u00f3rbita y, unos a\u00f1os despu\u00e9s, volvi\u00f3 para otros 437 d\u00edas.<\/p>","protected":false},"excerpt":{"rendered":"
