A Hold t\u00fal kicsi ahhoz, hogy leveg\u0151t tartson mag\u00e1ban. Sz\u00e9l hi\u00e1ny\u00e1ban a napos oldal forr\u00f3bb, mint a forr\u00e1sban l\u00e9v\u0151 v\u00edz, az \u00e9jszakai oldal viszont hidegebb, mint b\u00e1rhol a F\u00f6ld\u00f6n (m\u00ednusz 180 Celsius-fok).<\/p>\n<\/div>\n

A Holdr\u00f3l szerzett ismereteink nagy r\u00e9sze az 1960-as \u00e9s 1970-es \u00e9vekben m\u0171k\u00f6d\u0151 robot\u0171rszond\u00e1kb\u00f3l \u00e9s lesz\u00e1ll\u00f3egys\u00e9gekb\u0151l sz\u00e1rmazik. Egyes tud\u00f3sok \u00fagy v\u00e9lt\u00e9k, hogy a Holdra lesz\u00e1ll\u00f3 \u0171rhaj\u00f3 els\u00fcllyedne a poros felsz\u00ednen. Az amerikai \u00e9s orosz lesz\u00e1ll\u00f3egys\u00e9gek bebizony\u00edtott\u00e1k, hogy ez t\u00e9ves felt\u00e9telez\u00e9s volt. \u0150k egyengett\u00e9k az utat az emberek Holdra val\u00f3 utaz\u00e1sa el\u0151tt.<\/p>\n

Emellett k\u00f6zel 400 kg k\u0151zetet \u00e9s talajt hoztak vissza. A k\u00e9s\u0151bbi k\u00fcldet\u00e9sek sor\u00e1n az \u0171rhaj\u00f3sok egy akkumul\u00e1torral hajtott j\u00e1r\u00f3val j\u00e1rtak be a Holdat.<\/p>\n

Az elm\u00falt \u00e9vekben sz\u00e1mos orsz\u00e1g \u00fagy d\u00f6nt\u00f6tt, hogy visszat\u00e9r a Holdra.

Az egyik legfontosabb felfedez\u00e9s az volt, hogy a Hold p\u00f3lusai k\u00f6zel\u00e9ben l\u00e9v\u0151 kr\u00e1terek alj\u00e1n v\u00edzj\u00e9g tal\u00e1lhat\u00f3.

Eur\u00f3pa els\u0151 holdszond\u00e1ja a SMART-1 volt, amely 2004 november\u00e9t\u0151l 2006 szeptember\u00e9ig keringett a Hold k\u00f6r\u00fcl.
