Teadlased viivad l\u00e4bi katseid kaaluta olekus, mis viivad mitmesuguste uute l\u00e4bimurreteni! Aga mis siis, kui teie katse vajab osalist, kuid mitte t\u00e4ielikku kaaluta olekut? ESA, Saksamaa Kosmoseagentuur (DLR) ja Prantsuse Kosmoseagentuur (CNES) \u00fchendasid j\u00f5ud, et see teoks teha!<\/p>\n<\/div>\n<p>Kosmosesse mineku asemel kasutasid nad v\u00e4ga erilist lennukit nimega A310 Zero-G. \u00d5hus olles sooritab Zero-G piloot keerulise man\u00f6\u00f6vri. Ta t\u00f5mbab lennuki j\u00e4rsult \u00fclespoole ja v\u00e4hendab seej\u00e4rel t\u00f5ukej\u00f5udu. See paneb Zero-G-lennuki \u00f5hus suurt kaaret kirjutama, justkui oleks see katapultist v\u00e4lja tulistatud! Kui lennuk j\u00f5uab kaare tippu, on k\u00f5ik pardal olevad inimesed ja varustus umbes 20 sekundiks vabalanguses, mis on sama mis kaalutus. Seej\u00e4rel hakkab lennuk allapoole langema ja gravitatsiooni m\u00f5ju taastub. Varsti peab piloot lennukit \u00fcles t\u00f5mbama, et see \u00f5hus p\u00fcsiks, ja protsess v\u00f5ib uuesti alata!<\/p>\n<p>Et saavutada veerandi, poole ja kolme neljandiku gravitatsiooni m\u00f5ju, muutis piloot Zero-G \u00fclespoole suunduva lennu nurka, mille tulemusena lennuk j\u00e4rgis \u00f5hus teistsugust kaaret. Seda tehnikat polnud varem proovitud, kuid see toimis t\u00f5esti h\u00e4sti!<\/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>Kaotuse raskus<\/figcaption><\/figure>\n<p>Kolm kosmoseagentuuri tegid selle erakorralise lennu jooksul koost\u00f6\u00f6d erinevate katsete l\u00e4biviimisel. \u00dche katse raames uuriti osalise gravitatsiooni m\u00f5ju meie aju t\u00f6\u00f6tamisele. Varasemad katsed on n\u00e4idanud, et l\u00fchiajalised kaalutuse perioodid suurendavad verevoolu ajusse, mis aitab meie ajul paremini t\u00f6\u00f6tada. Pikaajaline kaalutus avaldab aga meie ajule negatiivset m\u00f5ju. Kas v\u00e4hendatud gravitatsiooniga v\u00f5iks olla hea kesktee? Just seda uurisidki m\u00f5ned pardal viibinud teadlased.<\/p>\n<p>Teine katse k\u00e4sitles taimede juurte k\u00e4itumist osalise gravitatsiooni tingimustes.
