China first announced the appearance of Mars Global names for official | Mars _ news

Original title: Mars Global Chinese names

1 launch

The long fifth launch Mars probe to fire directly into the transfer orbit. Most as far as 400 million km from Earth to Mars, detectors after about 7 months of the arrows separating cruising flight captured by Mars's gravity.

2 landing

After visiting the is separated from the surrounding land enters the Martian atmosphere through aerodynamic deceleration, parachute to slow down and reverse engine deceleration, and finally dropped landed in the Mars surface. Because the Rover will use solar power in China, from a lighting perspective, the ideal place is near the Martian equator, but the terrain near the Martian equator.

3 detection

Mars pulled off the landing platform, started inspections to detect the surface of Mars, Mars, topography, soil, environmental, atmospheric and study on distribution of water ice on Mars, physical field and internal structure. Due to the large distance data transmission delay, ask Rover must have a high degree of autonomy.

　　Rovers

Design life: 92 days

Design weight: 200duoqianke

Equipment: 4 solar panels

Is expected to launch in 2020, will achieve "orbiting, landing and inspection of" three main objectives

The Beijing news yesterday, Chinese Mars exploration program name and graphic identity global campaign launch ceremony held in Beijing. First official release of the Mars Rover and the Rover exterior styling.

　　Is expected to launch in Hainan by the long fifth

Mars is closer to the Earth's planets in the solar system, most similar to Earth and the natural environment, which is the preferred target for planetary exploration. China's first Mars exploration mission will be implemented in 2020, in one step "around, with, visiting" goal.

Mars exploration Mission Chief Designer Zhang Rongqiao introduces for the first time in China, is scheduled for July or August 2020, Hainan Wenchang satellite launch Center, the long fifth launch Mars probe to fire directly into the transfer orbit.

China's first Mars missions consultant, Commander-in-Chief and Chief Designer ye peijian Chang first satellite system introduced, Chinese Mars probe will reach Mars until July 2021. He said, the detector takes a long time to run before landing. Among them, the work surrounding the detector for about one Martian year, the equivalent of two years on Earth. Three Mars Rover can work months, equivalent to 92 Earth days.

China's first Mars missions project Deputy Director Liu Jizhong said, China's first Mars mission, not only to achieve orbit around Mars Global remote sensing, and to break the Mars entry, descent, landing and inspection of key technologies such as, remote monitoring and communication. 2020 China's first Mars probe into one of "orbiting, landing and inspection of" three goals that other countries implementation of Mars for the first time ever, facing the challenge is unprecedented.

　　26 month Mars launch opportunities

Liu Jizhong said from October 10, 1960, the Soviet Union launched the "Mars 1960A" probe so far, human organization a total of 43 times Mars missions, successful or partially successful 22 times, with a flight to Mars, technology has been successfully implemented on the fly, orbiting, landing and inspection of detection.

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. China's first Mars mission is to implement the innovation-driven development strategy an important initiative, after Lunar and deep space exploration, China is a major scientific and technological projects.

　　Secrets

　　Mars, what are the technical challenges?

Chief Designer of China's first Mars probe task Zhang Rongqiao introduced China's first Mars missions. He said, Mars distance Earth most far up 400 million km, detector in device arrows separation Hou after about 7 months cruise flight was Mars gravity capture, around device around Mars flight Hou to and landing visits device separation, then into task mission track carried out on Mars Global around detection, while for landing visits device carried out relay communications, this in track design Shang will both around and landing of needs.

Zhang Rongqiao said, after visiting the is separated from the surrounding land enters the Martian atmosphere, through aerodynamic deceleration, parachute to slow down and reverse engine power slowing last fall to land on the surface of Mars, Mars pulled off the landing platform, started inspections to detect the surface of Mars, Mars, topography, soil, environmental, atmospheric and study on distribution of water ice on Mars, physical field and internal structure. Due to the large distance data transmission delay, ask Rover must have a high degree of autonomy.

Said Zhang Rongqiao, and Mars light intensity is small, plus the Martian atmosphere to the Sun's action, energy supply than the Moon Rover cars more difficult. These Mars missions have more difficulty and complexity for the first time. "Despite the difficulties, but we still have to win the confidence of! ”

　　Where the Rover will land?

China's Mars probe is composed by the orbiting and landing inspections. Yesterday, the Academy of China Aerospace Science and Technology Group Chief Designer of the Mars Rover Sun Zezhou told reporters that Rover will land in North latitude and low latitude regions of Mars. "Now is a large region, did not say into which specific points. ”

Previously interviewed, introduced Sun Zezhou, probe closer to Mars, first of all, let it be captured by Mars's gravity, and fly around the Mars probe. Later, in appropriate time, separated from the surrounding land patrol will enter the Martian atmosphere, land surface and release the Rover to Mars, carry out inspections to detect. Meanwhile, the surrounding continue in orbit for scientific explorations, and Rovers to provide data relay services on the ground.

To the media, said Sun Zezhou, because the Rover will use solar power in China, from a lighting perspective, the ideal place is near the Martian equator, but the terrain near the Martian equator. In addition, due to land on Mars 99% deceleration deceleration is above the atmosphere and landing altitude lower gear longer, more secure the landing. "Considering the complexity of terrain, elevation, light intensity, temperature and other factors, more suitable landing sites on Mars at latitude 5 ° to 39 °. ”

中国火星探测器全球征名 官方首公布外观造型|火星探测器_新闻资讯

　　原标题：中国火星探测器全球征名

　1发射

　　由长征五号运载火箭将火星探测器直接送入地火转移轨道。火星距离地球最远达4亿公里，探测器在器箭分离后经过约7个月巡航飞行被火星引力捕获。

2着陆

　　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。由于中国火星车将使用太阳能供电，从光照角度考虑，最理想的地方是火星赤道附近，但是火星赤道附近的地形复杂。

3探测

　　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。

　　火星车

　　设计寿命：92天

　　设计重量：200多千克

　　设备：4个太阳能电池板

　　预计2020年发射，将一次实现“环绕、着陆、巡视”三大目标

　　新京报讯 昨日，中国火星探测工程名称和图形标识全球征集活动启动仪式在京召开。官方首次公布了火星探测器和火星车的外观造型。

　　预计在海南由长征五号发射

　　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，是人类开展行星探测的首选目标。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。

　　中国首次火星探测任务工程总设计师张荣桥介绍，预计在2020年七八月间，将在海南文昌发射中心，由长征五号运载火箭将火星探测器直接送入地火转移轨道。

　　中国首次火星探测任务顾问、嫦娥一号卫星系统总指挥兼总设计师叶培建介绍，中国的火星探测器将在2021年7月前到达火星。他表示，探测器要经 过一段时间的运行后才能着陆。其中，环绕探测器的工作时间约为一个火星年，相当于在地球上两年。火星车可以工作三个火星月，相当于地球上的92天。

　　中国首次火星探测任务工程副总指挥刘继忠说，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。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前所未有，面临的挑战也是前 所未有。

　　26个月一次火星探测发射机会

　　刘继忠表示，从1960年10月10日前苏联发射“火星1960A”探测器至今，人类共组织实施了43次火星探测任务，成功或部分成功22次，另有一次正在飞往火星，技术上已成功实现了越飞、环绕、着陆、巡视等探测。

　　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。中国实施首次火星探测任务，是落实创新驱动发展战略的一项重要举措，是探月工程之后中国深空探测又一重大科技工程。

　　■ 揭秘

　　探测火星有哪些技术难题？

　　中国首次火星探测任务工程总设计师张荣桥介绍了中国首次火星探测任务。他说，火星距离地球最远达4亿公里，探测器在器箭分离后经过约7个月巡航 飞行被火星引力捕获，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。

　　张荣桥表示，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。

　　张荣桥说，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。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！”

　　火星探测器将在哪里着陆？

　　中国火星探测器由环绕器和着陆巡视器组成。昨日，中国航天科技集团五院火星探测器总设计师孙泽洲告诉记者，火星探测器将在火星北纬低纬度区域着陆。“现在是大区域确定，并没有说落到哪个具体的点。”

　　此前接受采访时，孙泽洲介绍，探测器接近火星后，首先要让它被火星引力捕获，成为环绕火星飞行的探测器。之后，在合适时机，与环绕器分离的着陆 巡视器将进入火星大气，着陆到火星表面并释放火星车，开展巡视探测。与此同时，环绕器继续在轨道上进行科学探测，并为火星车提供对地面的数据中继服务。

　　孙泽洲此前向媒体表示，由于中国火星车将使用太阳能供电，从光照角度考虑，最理想的地方是火星赤道附近，但是火星赤道附近的地形复杂。另外，由 于登陆火星99%以上的减速是靠大气减速，因此着陆点海拔越低减速时间越长，登陆越安全。“综合考虑地形复杂度、高程、光照条件、温度等因素，火星比较适 合着陆点在北纬5°至39°的区域。”
