Kuidas aga meeskonnaliikmed seal \u00fcleval oma aega veedavad?

Spetsiaalselt varustatud moodulite, nagu n\u00e4iteks ESA Columbuse labor, abil saavad teadlased uurida mitmesuguseid teemasid v\u00e4ga erilises keskkonnas, kus valitseb kaalutus. Maal m\u00f5jutab gravitatsioon tugevalt k\u00f5ike, mida me teeme, kuid gravitatsiooni m\u00f5ju kadumisel juhtub m\u00f5ningaid v\u00e4ga kummalisi asju.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"200\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2007\/11\/A_flame_in_microgravity2\" 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\/2007\/11\/a_flame_in_microgravity2\/17893018-2-eng-GB\/A_flame_in_microgravity.jpg\" alt=\"A flame in microgravity\"><figcaption>Leek mikrogravitatsioonis<\/figcaption><\/figure>\n<p>Oleme harjunud n\u00e4gema k\u00fc\u00fcnlaleeki, millel on kooniline kuju. Terav leek tekib siis, kui kuumad gaasid t\u00f5usevad \u00fcles, sest need on kergemad kui neid \u00fcmbritsev jahe \u00f5hk. See jahe \u00f5hk imetakse k\u00fc\u00fcnla s\u00fc\u00fcte alusesse ja varustab leeki hapnikuga, et k\u00fc\u00fcnlavaha p\u00f5leks edasi. Kuid kaaluta olekus ei ole kuum gaas jahedast \u00f5hust kergem, mist\u00f5ttu see ei t\u00f5use \u00fcles. Selle tulemuseks on v\u00e4ike, peaaegu n\u00e4htamatu, \u00fcmmargune leek. Tegelik p\u00f5lemine toimub ainult leegi pinnal, kus k\u00fc\u00fcnlavahast p\u00e4rit k\u00fctus saab seguneda v\u00e4lis\u00f5hus oleva hapnikuga.<\/p>\n<p>Teadlased saavad palju teada, uurides, kuidas asjad kaaluta olekus p\u00f5levad. Neid teadmisi saab seej\u00e4rel kasutada n\u00e4iteks selliste auto- v\u00f5i lennukimootorite konstrueerimiseks, mis tarbivad v\u00e4hem k\u00fctust ja tekitavad v\u00e4hem saastet.<\/p>\n<p>Teine huvitav uurimisvaldkond on vedelike segamine. Paljud igap\u00e4evaselt kasutatavad metallid on sulamid \u2013 kahe v\u00f5i enama metalli segud. Sulameid valmistatakse metallide sulatamise teel, nii et need segunevad omavahel. Maal m\u00f5jutab gravitatsioon tugevalt seda, kuidas erinevad vedelad metallid \u00fchinevad, kuid kosmoses on segamine palju lihtsam. Katsed kaaluta olekus annavad meile selle protsessi kohta palju teavet, mis v\u00f5imaldab Maal valmistada paremaid sulameid.<\/p>","protected":false},"excerpt":{"rendered":"<p>A typical stay on board the International Space Station (ISS) lasts about six months.
