1960. aastate alguses viisid Ameerika \u00dchendriigid l\u00e4bi \u00fche k\u00fclma s\u00f5ja kummalisema kosmoseprojekti, mille k\u00e4igus toimetati Maa orbiidile sadu miljoneid pisikesi vaskn\u00f5elu. Eesm\u00e4rk oli luua kunstlik ioonikiht, mis v\u00f5imaldaks s\u00f5jav\u00e4el pidada side\u00fchendust ka siis, kui looduslik ionosf\u00e4\u00e4r peaks tuumaplahvatuste t\u00f5ttu h\u00e4iritud olema.<\/p>\n
K\u00fclma s\u00f5ja ajal s\u00f5ltus USA kaugside kas veealustest kaablitest \u2013 mida saanuks kriisiolukorras l\u00e4bi l\u00f5igata \u2013 v\u00f5i ionosf\u00e4\u00e4ri peegeldavatest raadiolainetest. Kardeti, et madalal Maa orbiidil toimuvad tuumaplahvatused v\u00f5ivad selle s\u00fcsteemi halvata. Lahendusena pakkusid USA s\u00f5jav\u00e4elased ja Massachusettsi Tehnoloogiainstituudi (MIT) teadlased v\u00e4lja idee viia kosmosesse hiiglaslik hulk mikroskoopilisi vasest dipoole, millest moodustuks kunstlik peegeldav v\u00f6\u00f6.<\/p>\n
Esimene katse 1961. aastal eba\u00f5nnestus, kuid 1963. aastal \u00f5nnestus nn Project West Fordi missioon, millega \u00f5nnestus saata orbiidile 120\u2013215 miljonit n\u00f5ela. Need pidid hajuma \u00fchtlaselt ning v\u00f5imaldama antennide ja v\u00f5imsate saatjate abil signaale edasi kanda. Eksperiment tekitas toona tugevat vastuseisu astronoomide seas, kes kartsid, et metalliosakesed segavad vaatlusi ja ohustavad satelliite. <\/p>\n
Kuigi projektiga demonstreeriti edukalt k\u00f5ne, teksti ja andmeside edastamist kahe USA jaama vahel, ei lagunenud k\u00f5ik n\u00f5elad ootusp\u00e4raselt. NASA andmetel p\u00fcsivad mitmed n\u00f5elakogumid orbiidil t\u00e4naseni. Kuigi p\u00e4ikesekiirgus m\u00f5jutab neid j\u00e4tkuvalt, ei ole need hajunud nii kiiresti, kui loodeti. Nii muutus ajutiseks kavandatud tehnoloogiline lahendus \u00fcheks varajaseks kosmosepr\u00fcgi n\u00e4iteks ehk probleemiks, millega inimkond tegeleb siiani.<\/p>\n
