Forskare genomf\u00f6r experiment i tyngdl\u00f6shet, vilket leder till alla m\u00f6jliga nya genombrott! Men vad h\u00e4nder om ditt experiment kr\u00e4ver delvis, men inte fullst\u00e4ndig, tyngdl\u00f6shet? ESA, det tyska rymdcentret (DLR) och den franska rymdorganisationen (CNES) har g\u00e5tt samman f\u00f6r att g\u00f6ra detta m\u00f6jligt!<\/p>\n<\/div>\n<p>I st\u00e4llet f\u00f6r att \u00e5ka ut i rymden anv\u00e4nde de ett mycket speciellt flygplan som kallas A310 Zero-G. N\u00e4r planet \u00e4r i luften utf\u00f6r Zero-G-piloten en kr\u00e4vande man\u00f6ver. De drar upp nosen kraftigt och minskar sedan dragkraften. Detta g\u00f6r att Zero-G f\u00f6ljer en stor b\u00e5ge i luften, som om det hade skjutits iv\u00e4g av en katapult! N\u00e4r flygplanet passerar toppen av sin b\u00e5ge befinner sig alla personer och all utrustning ombord i fritt fall, vilket \u00e4r detsamma som att vara tyngdl\u00f6sa, i cirka 20 sekunder. D\u00e4refter faller planet ned\u00e5t och tyngdkraften \u00e5terkommer. Det dr\u00f6jer inte l\u00e4nge f\u00f6rr\u00e4n piloten m\u00e5ste dra upp f\u00f6r att h\u00e5lla flygplanet i luften, och processen kan b\u00f6rja om igen!<\/p>\n<p>F\u00f6r att \u00e5stadkomma effekten av en fj\u00e4rdedel, h\u00e4lften och tre fj\u00e4rdedelar av tyngdkraften \u00e4ndrade piloten vinkeln p\u00e5 Zero-G-flygningen upp\u00e5t, vilket ledde till att planet f\u00f6ljde en annan b\u00e5ge i luften. Denna teknik hade inte pr\u00f6vats tidigare, men den fungerade riktigt bra!<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"2850\" data-credit=\"Novespace\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2018\/06\/Gravity_for_the_loss2\" 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\/2018\/06\/gravity_for_the_loss2\/17881179-2-eng-GB\/Gravity_for_the_loss.jpg\" alt=\"Gravity for the loss\"><figcaption>Gravitationen som orsak till f\u00f6rlusten<\/figcaption><\/figure>\n<p>De tre rymdorganisationerna samarbetade kring olika experiment under denna speciella rymdf\u00e4rd. Ett experiment unders\u00f6kte hur partiell tyngdkraft p\u00e5verkar hj\u00e4rnans funktion. Tidigare experiment har visat att korta perioder av tyngdl\u00f6shet \u00f6kar blodfl\u00f6det till hj\u00e4rnan, vilket bidrar till att hj\u00e4rnan fungerar b\u00e4ttre. Att vara i tyngdl\u00f6shet under en l\u00e4ngre tid har dock negativa bieffekter p\u00e5 v\u00e5ra hj\u00e4rnor. Kan det finnas en bra medelv\u00e4g med reducerad tyngdkraft? Det var just detta som n\u00e5gra av forskarna ombord unders\u00f6kte.<\/p>\n<p>Ett annat experiment handlade om v\u00e4xtr\u00f6tter och hur de reagerar p\u00e5 att befinna sig i delvis tyngdl\u00f6shet. Vi vet fr\u00e5n experiment ombord p\u00e5 den internationella rymdstationen att v\u00e4xter kan anpassa sig f\u00f6rv\u00e5nansv\u00e4rt snabbt, men vi beh\u00f6ver mer information f\u00f6r att fullt ut f\u00f6rst\u00e5 hur v\u00e4xterna f\u00f6r\u00e4ndras.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"3012\" data-credit=\"ESA - A.
