DevelopingIdeasReadingWhatisyourunderstandingofthistitle？Shareyouideaswithothers關(guān)于火星你了解多少？HowmuchdoyouknowaboutMars?火星（英語：Mars；拉丁語：Martis；天文符號：♂），是距離太陽第四近的行星，也是太陽系中僅次于水星的第二小的行星，為太陽系里四顆類地行星之一。歐洲古稱火星為“馬爾斯[43]”，古羅馬神話中的“戰(zhàn)神”，也被稱為“紅色星球”。古漢語中則因為它熒熒如火，位置和亮度時常變動而稱之為熒惑。其橘紅色外表是因為地表被赤鐵礦（氧化鐵）覆蓋，火星的直徑約為地球的一半，自轉(zhuǎn)軸傾角和自轉(zhuǎn)周期則與地球相近，但公轉(zhuǎn)周期是地球的兩倍。火星亮度最高可達(dá)-2.9等，但在大部分時間里比木星暗?；鹦谴髿庖远趸紴橹鳎?5.3%），既稀薄又寒冷，遍布撞擊坑、峽谷、沙丘和礫石，沒有穩(wěn)定的液態(tài)水。南半球是古老、充滿撞擊坑的高地，北半球則是較年輕的低地平原?；鹦巧献畲蟮幕鹕健獖W林帕斯山和最大的峽谷—水手號峽谷。火星有兩個天然衛(wèi)星：火衛(wèi)一和火衛(wèi)二，形狀不規(guī)則，可能是捕獲的小行星。根據(jù)觀測的證據(jù)，在火星觀察到類似地下水涌出的現(xiàn)象，南極冰冠有部分退縮，雷達(dá)數(shù)據(jù)顯示兩極和中緯度地表下存在大量的水冰。

火星有美國宇航局和歐洲發(fā)射的四艘在軌環(huán)繞探測器，分別是奧德賽號、火星快車號、火星全球勘測者和MAVEN火星探測器。表面還有多個美國的火星車，如好奇號、洞察號以及結(jié)束任務(wù)的火星探路者號、鳳凰號、勇氣號和機(jī)遇號等等。2021年5月15日，科研團(tuán)隊根據(jù)“祝融號”火星車發(fā)回遙測信號確認(rèn)，“天問一號”著陸巡視器成功著陸于預(yù)選著陸區(qū)，我國首次火星探測任務(wù)取得圓滿成功.Pre-readingDoyoureallyknowaboutMars?Choosethemagazineinwhichyouwouldmostlikelyfindthepassageandgiveyourreasons.1TheTraveller2AllAboutSpace3EnvironmentalConcerns4BiologyforFunPre-reading1WhatisPlanA?WhyisPlanBneeded?2WhyMars?While-reading
