Fargen fikk de gamle grekerne og romerne til \u00e5 oppkalle den etter sin krigsgud. I dag vet vi, takket v\u00e6re romfart\u00f8y som har bes\u00f8kt planeten, at planetens utseende skyldes rust i bergartene p\u00e5 Mars.<\/p>\n<\/div>\n<p>Mars er den fjerde planeten regnet fra Solen. Den g\u00e5r i bane rundt Solen i en gjennomsnittlig avstand p\u00e5 228 millioner km, halvannen gang s\u00e5 langt unna som Jorden, s\u00e5 menneskelige bes\u00f8kende ville oppleve det som sv\u00e6rt kaldt. Selv om somrene n\u00e6r ekvator kan v\u00e6re ganske varme, er gjennomsnittstemperaturen 63 grader Celsius under null \u2013 omtrent som vinteren i Antarktis. Nettene er ogs\u00e5 iskaldt.<\/p>\n<p>De f\u00f8rste menneskene p\u00e5 Mars vil st\u00e5 overfor andre utfordringer. Luften er 100 ganger tynnere enn p\u00e5 Jorden og best\u00e5r hovedsakelig av karbondioksid. De menneskelige oppdagelsesreisende vil m\u00e5tte bruke oksygenmasker og spesielle drakter hver gang de g\u00e5r ut av sine forseglede boliger.<\/p>\n<p>Voldsomme stormer kan virvle opp st\u00f8vskyer.
