Diese Farbe veranlasste die alten Griechen und R\u00f6mer dazu, ihn nach ihrem Kriegsgott zu benennen. Heute wissen wir dank der Raumsonden, die den Planeten besucht haben, dass sein Aussehen auf Rost in den Marsgesteinen zur\u00fcckzuf\u00fchren ist.<\/p>\n<\/div>\n<p>Der Mars ist der vierte Planet von der Sonne aus gesehen. Er umkreist die Sonne in einer durchschnittlichen Entfernung von 228 Millionen Kilometern, was der anderthalbfachen Entfernung der Erde entspricht; daher w\u00e4re es f\u00fcr menschliche Besucher dort sehr kalt. Obwohl die Sommer in der N\u00e4he des \u00c4quators recht warm sein k\u00f6nnen, liegt die Durchschnittstemperatur bei 63 Grad Celsius unter Null \u2013 \u00e4hnlich wie in den Wintern in der Antarktis. Auch die N\u00e4chte sind bitterkalt.<\/p>\n<p>Die ersten Menschen auf dem Mars werden mit anderen Problemen konfrontiert sein. Die Luft ist dort 100-mal d\u00fcnner als auf der Erde und besteht gr\u00f6\u00dftenteils aus Kohlendioxid. Die Forscher m\u00fcssen jedes Mal, wenn sie ihre hermetisch abgeschlossenen Unterk\u00fcnfte verlassen, Sauerstoffmasken und Spezialanz\u00fcge tragen.<\/p>\n<p>Heftige St\u00fcrme k\u00f6nnen Staubwolken aufwirbeln.
