1957. aastal sai Sputnikist esimene tehis satelliit, mis j\u00f5udis edukalt kosmosesse. Sellest ajast alates on orbiidile saadetud tuhandeid satelliite. Need satelliidid, mis t\u00e4na meie planeeti \u00fcmbritsevad, on andnud meile v\u00f5imaluse leida igalt poolt tee koju, suhelda igal ajal inimestega \u00fcle kogu maailma, j\u00e4lgida kaduvaid metsi ja j\u00e4\u00e4katteid ning isegi ennustada looduskatastroofe.<\/p>\n

Kuid satelliitide ajastu on t\u00e4itnud Maa \u00fcmbruse kosmose ka suurte inertse metalli t\u00fckkidega. Hinnanguliselt tiirleb planeedi \u00fcmber 30 000 suurt kosmosepr\u00fcgi t\u00fckki. Nende hulka kuulub k\u00f5ike alates kasutusest k\u00f5rvaldatud satelliitidest ja rakettide j\u00e4\u00e4kidest kuni astronautide kindadeni. See arv kasvab pidevalt!<\/p>\n

Lisaks on olemas miljoneid v\u00e4iksemaid kosmoseprahi t\u00fckke, nagu mutrid, poldid ja isegi v\u00e4rvipisaraid. Paljud neist liiguvad \u00fcmber planeedi kiirusega 7 km sekundis. Sellise kiiruse juures v\u00f5ib v\u00e4rvipisara m\u00f5ju olla sama suur kui 95 km tunnis liikuv mootorratas!<\/p>\n

Selline kokkup\u00f5rge kahjustaks iga satelliiti v\u00f5i kosmosejaama ning tekitaks uusi ohtlikke kosmoseprahi t\u00fckke. Seet\u00f5ttu on ESA pannud m\u00f5ned oma parimad m\u00f5tlejad t\u00f6\u00f6le, et leida lahendus sellele keerulisele probleemile. Noh, v\u00f5ib-olla on nad just leidnud ideaalse lahenduse, kasutades \u00fcht inimkonna vanimatest tehnoloogiatest \u2013 kalav\u00f5rku.<\/p>\n

Spetsiaalselt selleks otstarbeks loodud v\u00f5rkude abil, mida kosmoselaevadest v\u00e4lja lastakse, saame surnud satelliite kinni p\u00fc\u00fcda ja need maale tuua. Seda geniaalset ideed testitakse praegu kaaluta olekus ning kui k\u00f5ik l\u00e4heb h\u00e4sti, k\u00e4ivitatakse ESA missioon \u2018e.Deorbit\u2019 2021. aastal ja saame m\u00f5ned satelliidid kinni p\u00fc\u00fcda!<\/p>\n

Huvitav fakt:<\/b> Et p\u00fcsida kosmoses ja v\u00e4ltida tagasikukkumist Maale, peab satelliit tiirlema meie planeedi \u00fcmber kiirusega \u00fcle 28 200 kilomeetrit tunnis!<\/p>","protected":false},"excerpt":{"rendered":"
