Astronaut Alexander Gerst are imminent after his return from space, exhausting days. The body of 42-Year-old will have to get used again to the earth – especially to the force of gravity.
“The adjustment process takes place at the most within three days. For some it takes a little longer, some shorter,” said Claudia Stern, head of the Department of Clinical aerospace medicine at the German center for air and space travel (DLR) in Cologne, the German press Agency.
Gerst was returned on Thursday to the earth. Almost 200 days he had spent previously on the International space station ISS in space before he landed in a Soyuz capsule in Kazakhstan. For the 42-Year-old, it was already the second Mission to the Outpost of humanity. On Thursday evening, he flew to Cologne, where Gerst will spend in a medical research facility of the DLR for the night.
In the first few weeks will deal with the Astronaut, now mainly with “Baseline Data Collections”, such as Marco Trovatello, a spokesman for the European astronauts centre in Cologne, said. “Simplifying The repetition of a large number on Board the ISS, said: – conducted scientific and technical experiments,” he added. The goal is to be able to the data and rate comparisons.
At Christmas, Astro-Alex-free “” however, and can home. He should also get to rest. “Alexander Gerst is first to make his medical convalescence. And then he will surely make a break – he was for a while in an extreme environment,” said mission Manager Volker Schmid from the DLR.
What is the impact of the extreme conditions in space on the body, can be thought of as a normal mortal. It begins with the landing on earth – if gravity strikes again. Astronauts describe the onset of a feeling of heaviness about with quicksand or a bog.
Gerst said after landing, for example, that the balance must come with a purpose in the swing. “It was almost a half a year break,” he said. Added to this may be muscle soreness. To larger problems he had observed on the ISS for an iron sports program – and for good reasons.
“In All, when Hovering, you need specifically the leg muscles, as well as not. If astronauts don’t exercise, you lose, in extreme cases, up to 40 percent of the leg muscles,” explained the expert star. Climbing stairs is a pretty strenuous affair was to rise under these conditions, first.
cardiovascular, muscles, bone, eye much changes when one is so far from earth. For example in the head. “In All, one gets a real skull, because the weightlessness more blood in the head is flowing,” said star. The positive effect: This skull will disappear on return. The disadvantage is that It shoots to the bottom. “All the blood pools in the legs. You can get thick legs and circulatory problems,” said star. Also bone, there is swelling of the optic nerve head and often the eyeballs shorten.
Until everything is really back in the series, takes it from the space traveler has a different length. “Bone building takes the longest, this can take up to two years. Eye changes can remain in individual cases,” said star. Everything else leave in the rule of law quickly rebuild.
Whether Germany’s Star Astronaut, all these hardships will eventually expose a third Time, is yet open. “What will make Alexander Gerst in the future, will clarify, perhaps, in the course of the next year,” said mission leader Schmid. But he think it is unwise to allow him more time to fly.
The US, for example, want to go around 2023 for the first time in decades the moon with a manned Orion spacecraft, which is currently being built in co-operation with Europe. “A candidate for the moon – if a European is – would he, in any case,” said Schmid.
