人類(lèi)已經(jīng)做了很多關(guān)于宇宙的研究.人類(lèi)甚至已經(jīng)發(fā)明了4種衛(wèi)星.第一種用于研究地球地理,即我們的家園.它被用來(lái)繪制地圖以及幫助一些國(guó)家尋找石油與黃金.
第二種衛(wèi)星用于飛機(jī)和輪船的導(dǎo)航.一艘輪船或一架飛機(jī)可以發(fā)送信號(hào)到衛(wèi)星從而確定其當(dāng)前的方位.
第三種衛(wèi)星用于研究天氣.這類(lèi)衛(wèi)星用來(lái)觀測(cè)地球表面風(fēng)云的移動(dòng).當(dāng)惡劣天氣要來(lái)的時(shí)候,他們可以警告使用這種衛(wèi)星的國(guó)家做好防御準(zhǔn)備.它們?cè)诰嚯x地表幾千公里外拍下照片并傳送到地面氣象站.
最后一種用于通訊.國(guó)家間的電話通話可用這類(lèi)衛(wèi)星傳送.有些衛(wèi)星支持成千上萬(wàn)部電話同事接打.撥打電話時(shí),信號(hào)先被發(fā)到衛(wèi)星,然后衛(wèi)星再講信號(hào)發(fā)到另一國(guó)的基站.這類(lèi)衛(wèi)星也可傳送照片,一次可以收發(fā)8張.
