Een voorbeeld hiervan is dat wij kooldioxide uitademen, maar dat planten en kleine organismen zoals algen in de oceaan dit opnemen en het weer omzetten in zuurstof, zodat wij opnieuw kunnen ademen. Maar hoe recyclen astronauten lucht en water op het Internationaal Ruimtestation (ISS)?<\/p>\n<p>In het Internationaal Ruimtestation vraagt Paxi zich af waarom het daar zo veilig en comfortabel aanvoelt. Gelukkig is NASA-astronaut Stephen Bowen in de buurt om Paxi uitleg te geven over het \u201cClosed Loop System\u201d, dat astronauten helpt om langer in de ruimte te verblijven en zelfs wat geld bespaart!<\/p>\n<p>Lange tijd haalden astronauten hun zuurstof uit water (dat bestaat uit waterstof en zuurstof) dat vanaf de aarde werd aangevoerd. Maar nu kunnen zij dankzij het \u201cClosed Loop System\u201d elk jaar genoeg water besparen om een groot bad te vullen \u2014 en dat is heel veel water!<\/p>\n<p>Ga met Paxi en Stephen mee op ontdekkingstocht naar hoe astronauten leven en ademen op het ISS!\u00a0<\/p>\n<figure class=\"wp-block-embed is-type-video\"><iframe width=\"728\" height=\"410\" src=\"https:\/\/www.youtube.com\/embed\/tmqQMUB9mdI?si=aeMmc0dZTZ-I6L4g\" frameborder=\"0\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/figure>","protected":false},"excerpt":{"rendered":"<p>Have you ever thought about how the Earth has everything we need to live?
