Apr\u00e8s une mission spatiale dont la dur\u00e9e peut varier entre une semaine et six mois, que deviennent les membres de l'\u00e9quipage de retour sur Terre ? En quelques heures, ils passent d\u2019un environnement d\u2019apesanteur \u00e0 la gravit\u00e9 normale. Apr\u00e8s avoir v\u00e9cu dans un espace o\u00f9 tout avait tendance \u00e0 flotter, ils reviennent sur une plan\u00e8te o\u00f9 chaque mouvement demande un effort.<\/p>\n<\/div>\n

La r\u00e9adaptation \u00e0 la gravit\u00e9 terrestre est difficile parce que leurs muscles et leurs os se sont affaiblis et que leur c\u0153ur doit travailler beaucoup plus pour pomper le sang dans tout le corps. Les astronautes qui rentrent sur le vaisseau Soyouz doivent \u00eatre aid\u00e9s par du personnel de secours russe pour sortir et ils sont port\u00e9s jusqu\u2019\u00e0 des h\u00e9licopt\u00e8res qui les attendent pour la premi\u00e8re partie de leur trajet jusqu\u2019\u00e0 leur foyer.<\/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

D\u2019autres effets secondaires mettent plus longtemps \u00e0 \u00eatre surmont\u00e9s. La r\u00e9duction de la densit\u00e9 osseuse accro\u00eet les risques de fractures. L\u2019affaiblissement des muscles rend plus difficiles des gestes quotidiens comme celui de soulever le moindre objet. Et pourtant, il est difficile de r\u00e9sister aux merveilles de l\u2019espace. Huit personnes se sont rendues au moins six fois dans l\u2019espace. Le Russe Valeri Polyakov a pass\u00e9 240 jours en orbite, avant de repartir quelques ann\u00e9es plus tard pour un vol de 437 jours !<\/p>","protected":false},"excerpt":{"rendered":"
