China Youth online Beijing, August 23 (China Youth Daily: China Youth online reporters Qiu Chen Hui Ouyang Yi Lan intern) today held in Beijing "Chinese Mars exploration program name and graphic identity global campaign" Press Conference, published for the first time a Chinese Mars Exploration Rover and the Rover design configurations, this is China's first Mars probe and Mars Rovers. Prior to that, Defense Science and Industry Council has already said, China's first Mars exploration mission will be implemented in 2020, in one step "around, with, visiting" goal.

Mars is closer to the Earth's planets in the solar system, most similar to Earth and the natural environment, is the preferred destination for human interplanetary. However, constrained by a celestial rule, only once every 26 months exploring Mars favorable launching opportunity, only 3 times before and after between now and 2020 launch opportunity, 4 Mars missions will be launched, will usher in the international Mars exploration rush.

In day activities of Mr in the, China first Mars detection task engineering Deputy Commander, and exploration months and space engineering Center Director Jizhong Liu said, China first Mars detection task, not only to achieved around Mars Global remote sensing detection, also to breakthrough Mars into, and declined, and landing, and visits, and far distance control communications, key technology, makes we real into deep empty, go near Mars opened she mystery of veil, this is belongs to whole Chinese all people of pride and proud.

Chief Designer of China's first Mars probe task during the meeting, Zhang Rongqiao introduced China's first Mars missions mentioned in 2020, China's first Mars probe into one of "orbiting, landing and inspection of" three goals that other countries from the failed implementation of Mars for the first time, facing the challenge is unprecedented.

Lander

Zhang Rongqiao says most up to 400 million km from Earth to Mars, probe arrows after separation would require cruise flight about 7 months to be captured. Fly around the orbit around Mars after landing and tour players separation and surrounded into mission orbit of Mars Global detection and relay communications for the landing inspections, which will demand both orbiting and landing on the track design.

Zhang Rongqiao also mentioned, landing visits device and around device separation Hou into Mars atmosphere, after pneumatic shape deceleration, and parachute deceleration and anti-push engine power deceleration, last declined landing in Mars surface, Mars car drove away from landing platform, began Mars surface visits detection, to detection Mars of morphology, and soil, and environment, and atmosphere, research Mars Shang of water ice distribution, and physical field and internal structure.

Due to the large distance data transmission delay, ask Rover must have a high degree of autonomy. Meanwhile, Mars light intensity is small, plus the Martian atmosphere to the Sun's action, energy supply than the Moon Rover cars more difficult. Zhang Rongqiao said, "has made the first Mars missions more difficult and complicated. Despite the difficulties, but we still have to win the confidence of! ”

Day of China Mars detection engineering name and graphics identifies global collection activities, by national defense section workers Council exploration months and space engineering center hosted, national defense section workers Council news publicity Center, and CAs Moon and deep empty detection General Department, and China space technology group aerospace Department, and China rocket technology Institute, and China space technology Institute, and Shanghai space technology Institute, organised, youchange Ben months space technology (Beijing) limited responsibility company, and in the vision international spread Group, and Xinhua Corporation, and Tencent technology (Beijing) limited, Switzerland pioneering tab contractors such as taigehaoya.

中国火星探测器外观首次公布

　　原标题：中国火星探测器外观首次公布（组图）

中国第一个火星探测器外观设计构型图

　　中青在线北京8月23日电（中国青年报·中青在线记者 邱晨辉 实习生欧阳伊岚）今天，在北京举办的“中国火星探测工程名称和图形标识全球征集活动”新闻发布会，首次公布了中国火星探测器和火星车外观设计构型，这是中国第一个火星探测器和火星车。在此之前，国防科工局已发布消息称，中国首次火星探测任务将于2020年实施，一步实现“绕、着、巡”的目标。

　　火星，是太阳系中离地球较近的行星，而且自然环境与地球最为类似，是人类开展行星际探测的首选目标。不过，受天体运行规律的约束，每26个月才有一次火星探测有利发射时机，从现在起到2020年前后仅有的3次发射机会，将有4次火星探测任务发射，在国际上将迎来火星探测的高峰。

　　在当天活动的致辞中，中国首次火星探测任务工程副总指挥、探月与航天工程中心主任刘继忠表示，中国首次火星探测任务，不仅要实现环绕火星全球遥感探测，还要突破火星进入、下降、着陆、巡视、远距离测控通信等关键技术，使我们真正进入深空，走近火星揭开她神秘的面纱，这是属于整个中华民族全体人民的骄傲和自豪。

　　中国首次火星探测任务工程总设计师张荣桥在会上介绍中国首次火星探测任务时提到，2020年中国首次火星探测一次实现“环绕、着陆、巡视”三个目标，这是其他国家第一次实施火星探测从所未有，面临的挑战也是前所未有。

着陆器

　　张荣桥说，火星距离地球最远达4亿公里，探测器在器箭分离后需经过约7个月巡航飞行才能被火星捕获。环绕器环绕火星飞行后要与着陆巡视器分离，然后进入任务使命轨道开展对火星全球环绕探测，同时为着陆巡视器开展中继通讯，这在轨道设计上就要兼顾环绕和着陆的需求。

　　张荣桥还提到，着陆巡视器与环绕器分离后进入火星大气，经过气动外形减速、降落伞减速和反推发动机动力减速，最后下降着陆在火星表面，火星车驶离着陆平台，开始火星表面巡视探测，要探测火星的形貌、土壤、环境、大气，研究火星上的水冰分布、物理场和内部结构。

　　由于远距离数据传输的大时延，要求火星车必须具有很高的自主能力。同时，火星光照强度小，加上火星大气对阳光的削减作用，火星车能源供给也比月球车更为困难。张荣桥说，“这些都使得首次火星探测任务更具难度和复杂性。虽然困难重重，但我们仍然抱有必胜的信心！”

　　当天的中国火星探测工程名称和图形标识全球征集活动，由国家国防科工局探月与航天工程中心主办，国家国防科工局新闻宣传中心、中科院月球与深空探测总体部、中国航天科技集团公司宇航部、中国运载火箭技术研究院、中国空间技术研究院、上海航天技术研究院等协办，由嫦娥奔月航天科技（北京）有限责任公司、中宣国际传播集团、新华网股份有限公司、腾讯科技（北京）有限公司、瑞士先锋制表泰格豪雅等承办。
