Was aber geschieht eigentlich, wenn die Besatzungsmitglieder zur Erde zur\u00fcckkehren? Innerhalb weniger Stunden werden sie von einer schwerelosen Umgebung in die normale Schwerkraft zur\u00fcckversetzt. Vom Leben an einem Ort, an dem alles schwebt, kommen sie zur\u00fcck auf einen Planeten, auf dem jede Bewegung Anstrengung bedeutet.<\/p>\n<\/div>\n<p>Die Wiedergew\u00f6hnung an die Erdanziehungskraft ist schwierig, da ihre Muskeln und Knochen geschw\u00e4cht sind und das Herz wesentlich st\u00e4rker arbeiten muss, um das Blut durch den K\u00f6rper zu pumpen. Die an Bord der Sojus zur\u00fcckkehrenden Astronauten m\u00fcssen f\u00fcr den ersten Teil ihrer Heimreise von russischen Rettungskr\u00e4ften aus dem Raumschiff gehoben und zu wartenden Hubschraubern getragen werden.<\/p>\n<p>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 &#8211; 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<p>Andere Begleiterscheinungen lassen sich nicht so schnell \u00fcberwinden. Da die Knochendichte abnimmt, kommt es leichter zu Knochenbr\u00fccken. Durch die geschw\u00e4chten Muskeln wird es zu einer Anstrengung, selbst leichte Gegenst\u00e4nde zu heben oder allt\u00e4gliche T\u00e4tigkeiten auszuf\u00fchren. Trotz allem l\u00e4sst sich den Wundern der Weltraumfahrt nur schwer widerstehen. Acht Personen haben sich bereits mindestens sechs Mal ins All begeben. Der Russe Valeri Poljakow hat 240 Tage in einer Erdumlaufbahn verbracht und flog ein paar Jahre sp\u00e4ter erneut f\u00fcr 437 Tage ins All!<\/p>","protected":false},"excerpt":{"rendered":"<p>A space mission may last anything from a week to six months, but what happens when the crew returns to Earth?
