Det er en stor udfordring at holde sig i form og bevare en god muskelstyrke, da muskler og knogler har tendens til at blive svagere i v\u00e6gtl\u00f8shed. At sv\u00e6ve rundt p\u00e5 Den Internationale Rumstation er rigtig sjovt, men det er ikke godt for helbredet, n\u00e5r man er der i mange m\u00e5neder!<\/p>\n<\/div>\n<p>ESA-forskere arbejder p\u00e5 at hj\u00e6lpe astronauterne med at l\u00f8se dette problem. De bruger en orm med det f\u00e6ngende navn <i>Caenorhabditis elegans<\/i> (<i>C. elegans <\/i>(forkortet) for at hj\u00e6lpe dem. De fandt ud af, at musklerne i <i>C. elegans<\/i> reagerer p\u00e5 v\u00e6gtl\u00f8shed p\u00e5 en m\u00e5de, der minder meget om menneskelige muskler. M\u00e5ske kunne disse sm\u00e5 orme \u2013 som hver is\u00e6r er under 1 mm lange \u2013 bruges i eksperimenter i rummet for at bidrage til denne forskning?<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"4928\" data-credit=\"ESA\/NASA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2015\/09\/Samantha_running_in_space\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2015\/09\/samantha_running_in_space\/15629558-1-eng-GB\/Samantha_running_in_space.jpg\" alt=\"Samantha running in space\"><figcaption>Samantha l\u00f8ber i rummet<\/figcaption><\/figure>\n<p>Tim Etheridge er lektor ved University of Exeter i Storbritannien.

Derefter blev de lastet ombord p\u00e5 et Dragon-rumfart\u00f8j og sendt op til Den Internationale Rumstation! ESA-astronauten Alexander Gerst placerede ormene i en inkubator, der var designet til at hj\u00e6lpe dem med at vokse hurtigt og sikkert. Mindre end en uge senere var de fuldt udvoksede, alt sammen under v\u00e6gtl\u00f8se forhold. Ormene blev derefter nedfrosset, klar til at blive sendt tilbage til Jorden til unders\u00f8gelse. I mellemtiden er der blevet opdr\u00e6ttet andre grupper af orme under normale forhold p\u00e5 Jorden, s\u00e5 man kan sammenligne forskellene.<\/p>\n<p>Missionens forskere h\u00e5ber, at eksperimentet ogs\u00e5 vil hj\u00e6lpe os med at l\u00e6re mere om en mulig \u00e5rsag til diabetes og en sygdom kaldet muskeldystrofi, hvor musklene sv\u00e6kkes og nedbrydes. Forskningen vil alts\u00e5 ikke kun hj\u00e6lpe astronauter i rummet, men ogs\u00e5 mennesker med sygdomme her p\u00e5 Jorden!<\/p>\n<p><i>Interessant faktum: Det var et kapl\u00f8b mod tiden at f\u00e5 ormene ud i rummet, da de kun kunne overleve i 160 timer, f\u00f8r de skulle v\u00e6re inde i rumstationens inkubator<\/i><\/p>","protected":false},"excerpt":{"rendered":"<p>Going into space is an exciting adventure, but some things are very difficult for astronauts.
