N\u00e5r mennesker befinder sig i rummet, fungerer deres immunsystem (det er den del af vores krop, der beskytter os mod sygdomme) ikke lige s\u00e5 godt som p\u00e5 Jorden. For at hj\u00e6lpe os med at forst\u00e5, hvorfor det er s\u00e5dan, har forskerne sendt menneskelige immunceller ombord p\u00e5 Dragon.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1024\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2015\/01\/Dragon_approaching_ISS\" 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\/01\/dragon_approaching_iss\/17890429-2-eng-GB\/Dragon_approaching_ISS.jpg\" alt=\"Dragon approaching ISS\"><figcaption>Dragen n\u00e6rmer sig ISS<\/figcaption><\/figure>\n<p>Disse celler er udvundet fra frisk humant blod og overlever kun 120 timer, n\u00e5r de f\u00f8rst er ude af det!

Efter en to-dages flyvning ombord p\u00e5 Dragon skulle cellerne placeres i en inkubator s\u00e5 hurtigt som muligt. Det n\u00e6ste skridt er at udl\u00f8se cellernes naturlige forsvar mod sygdomme. Derefter vil de blive nedfrosset, klar til at blive sendt tilbage til Jorden til yderligere analyse.<\/p>\n<p>Astronauterne vil desuden frembringe en kunstig infektion for at aktivere immunceller, der er udtaget fra andre livsformer, herunder rotter og muslinger.
