Day boat, first published with the temple on the second task: 3 "space filling"
About to undertake day long seventh boat, first launch was China's new medium launch vehicle, near-Earth orbits carrying capacity of 13.5 tons in June last year a successful maiden flight. Xinhua News Agency (information)4th, spokesman of the China manned space engineering, said, according to Xinhua, day boat first cargo spacecraft will be launched in late April at the Wenchang space launch and in-orbit repair of cargo transportation, supply, propellant and fast rendezvous and docking and a number of key technologies, independent tests. This is the Chinese manned space laboratory of the final battle, and smooth implementation of the follow-up mission to space station is of great significance, marking the success of China's manned space engineering "three-step" strategy in the "second step" mandates, solid technology foundation for the space station construction mission.
As planned, the boat after the first was launched into orbit, and in-orbit operation of temple on the second has 3 independent quick rendezvous and docking, 3 propellant added in orbit, space applications and space technology and other areas of real (test) test project. Meanwhile, day boat, first fitted with the temple on the second group in orbit for about 2 months, day boat, first independent flight for about 3 months. After you complete the tasks, day boat first controlled de-orbit, falling to a predetermined safe waters; Temple on the second rail continued to expand testing and applications.
Now, day boat first mission preparations are on schedule tight. Which, days boat first, freight spacecraft is launch site district carried out related test work; launches days boat first, of March seventh, away two rocket, has completed factory Qian of the prepared work; various space test load, has completed products production and test work; Temple second, in rail run State good; Wenchang space launch site, and control communications system and station system, is by plans for task related prepared work.
China manned space engineering on September 21, 1992 the project since 25 years and always press the "three-step" step to promote the implementation of the strategy. At present, construction of space station research efforts are steadily advancing, follow-up will launch the space station core module and module, planned for completion in 2022 Assembly on-orbit construction of the station.
2017, China's space program revealed
"Goddess" Lunar soil mining "Beidou" covered the new global satellite
Chang fifth 380,000 kilometers on the mining of Lunar soil
Chang fifth China has so far developed the most difficult, tasks most complex spacecraft. As planned, the Chang fifth will be around the end of November this year launched from Wenchang space launch site in China.
Academy of China Aerospace Science and Technology Corporation introduced lunar exploration satellite as Commander and Chief Architect Advisor ye peijian, 8.2-ton Chang fifth to four for the first time since China carried out space activities: automatic sampling on the lunar surface for the first time; took off from the lunar surface for the first time; the Moon 380,000 kilometers away for the first time unmanned rendezvous and docking in orbit; the first returned to Earth with Lunar soil with closest ratiocination.
If all goes well, the whole process will be completed within 1 month, 2017 will be within 2 kg of Lunar soil "package" back to Earth. "By then, China's moon probe completed three month target. "Ye peijian said.
Global Beidou navigation service area coverage
Chinese Beidou navigation satellite system also have big moves this year. Third satellite of the Big Dipper first launch is planned for around July. Big plans to launch third satellite this year 6 to 8, will implement several arrows double satellite launches.
Introduction to China Aerospace Science and Technology Corporation Bao Weimin, Director of the CST, the Big Dipper, third service area from BD the second world one-third to global satellite performance has increased dramatically, single design life of 12 years. Third system between the stars of the Big Dipper transmission transmission function, Foundation design, achieving a high orbit and low Earth orbit satellites and Earth stations link exchange.
Following the 2016 after the successful launch of 3 new generation Beidou navigation satellite, China has 22 Beidou navigation satellites in orbit, including new satellite 7.
6 new satellite on the aircraft's high-speed rail, power NET
In 2017, China plans to launch practice 13th (Star 16th), practice, stars in the 18th, 9A, Star 9C all 6 communications satellite, which China communications satellite technology to further develop the international forefront.
Academy of China Aerospace Science and Technology Corporation Wang Min, Vice Minister of communications satellite Division introduced, in April, the first high-throughput communication satellite will be launched in China practice, 13th (Star 16th). The satellite in orbit for the first time on application of laser communication and electric propulsion technology, communications a total capacity of more than 20G, more than China, which sum of all satellite capacity.
In June, the takeoff weight of up to 7 tons of practice 18th satellite launch, it uses the newly developed bearing capacity of China's largest satellite platform, DFH fifth, can compare favourably with the most advanced communications satellite platform.
Wang Min said on the airplane, high-speed rail, future smooth access to the Internet, watch, 4K ultra HD programs fulfilled by high-throughput communication satellites in the sky.
A large dial watch home satellite coming soon
This year, there is a whole bunch of applications of new technologies, new skills, new satellites will be launched one after another, they use the Starlight, watching the people's happy life on Earth.
Astrologers know Fengyun meteorological satellite family heating and cooling is expected to fact; the hard x-ray modulation telescope satellite is expected to launch this year; referred to as "Zhang Heng's first" the first electromagnetic monitoring satellites is expected to launch in the second half, will make China the only on-orbit operation of multiple loads, high-precision seismic monitoring experiment satellite countries.
Meanwhile, China's rapid development of commercial space. This year, China 0.5-meter--Takakage first high-resolution commercial remote sensing satellite will usher in two new star, followed by 0.5 meters of 4 satellites in orbit high resolution optical remote sensing satellite will complete the network, achieving any place in the world revisited once a day.
This year, the Rainbow project of China Aerospace Science and industry Corporation first star will also launch technical validation, after the project is completed, to allow people in any corner of the world connected to the Internet.

天舟一号与
天宫二号任务公布：3次“太空加油”
即将承担天舟一号发射任务的长征七号是中国新一代中型运载火箭,近地轨道运载能力13.5吨,去年6月首飞成功。新华社(资料图) 据新华社电 中国载人航天工程新闻发言人4日表示,天舟一号货运飞船将于4月中下旬在文昌航天发射场发射,并开展货物运输补给、推进剂在轨补加、自主快速交会对接等多项关键技术试验。这是中国载人航天工程空间实验室阶段的收官之战,对于空间站工程后续任务顺利实施具有极为重要的意义,将标志着中国载人航天工程胜利完成“三步走”战略中的“第二步”任务,为空间站建设任务奠定坚实技术基础。
按计划,天舟一号发射入轨后,将与在轨运行的天宫二号先后进行3次自主快速交会对接、3次推进剂在轨补加,以及空间应用和航天技术等多领域的实(试)验项目。其间,天舟一号与天宫二号组合体在轨飞行约2个月,天舟一号独立飞行约3个月。完成既定任务后,天舟一号将受控离轨,陨落至预定安全海域;天宫二号留轨继续开展拓展试验和应用。
目前,天舟一号飞行任务各项准备工作正按计划紧张开展。其中,天舟一号货运飞船正在发射场区开展相关测试工作;发射天舟一号的长征七号遥二火箭,已完成出厂前的各项准备工作;各类空间试验载荷,已完成产品生产和测试工作;天宫二号在轨运行状态良好;文昌航天发射场、测控通信系统和空间站系统,正在按计划进行任务相关准备工作。
中国载人航天工程自1992年9月21日立项以来,25年间始终按“三步走”战略分步推动实施。当前,空间站研制建设各项工作正在稳步推进,后续将先后发射空间站核心舱和实验舱,计划2022年完成空间站的在轨组装建造。
中国2017年太空计划全揭秘
“嫦娥”采月壤 “北斗”覆全球 新技能卫星上天
嫦娥五号38万公里外采回月壤
嫦娥五号是中国迄今研制的难度最大、任务最复杂的航天器。按计划,嫦娥五号将在今年11月底前后从中国文昌航天发射场发射升空。
中国航天科技集团公司五院月球探测卫星总指挥兼总设计师顾问叶培建介绍,8.2吨重的嫦娥五号将实现中国开展航天活动以来的四个首次:首次在月球表面自动采样;首次从月面起飞;首次在38万公里以外的月球轨道上进行无人交会对接;首次带着月壤以接近第二宇宙速度返回地球。
如果进展顺利,整个过程将在1个月内完成,2017年内就能将2公斤的月壤“打包”回地球。“届时,中国探月三期的目标就全部完成。”叶培建说。
北斗导航服务区域覆盖全球
中国北斗导航卫星系统今年也有大动作。北斗三号卫星计划在7月左右进行首次发射。北斗三号卫星今年计划发射6至8颗,将实施数次一箭双星发射。
中国航天科技集团公司科技委主任包为民介绍,北斗三号服务区域将从北斗二号时的覆盖全球三分之一扩大到全球;卫星性能也大幅提升,单星设计寿命达到12年。北斗三号系统采取了星间传输、地基传输功能一体化设计,实现了高轨、低轨卫星及地面站的链路互通。
继2016年成功发射3颗新一代北斗导航卫星后,目前中国已有22颗北斗导航卫星在轨运行,其中新一代卫星7颗。
6颗新卫星助力人们在飞机高铁上触网
2017年,中国计划发射实践十三号(中星16号)、实践十八号、中星9A、中星9C等共6颗通信卫星,使中国的通信卫星技术进一步迈向国际前列。
中国航天科技集团公司五院通信卫星事业部副部长王敏介绍,4月,中国将发射首颗高通量通信卫星实践十三号(中星16号)。这颗卫星首次在高轨道上应用激光通信和电推进等技术,通信总容量达20G以上,超过中国此前所有通信卫星容量的总和。
6月,起飞重量达7吨的实践十八号卫星计划发射,它所采用的中国最新研发的承载能力最大的东方红五号卫星平台,能与国际上最先进的通信卫星平台媲美。
王敏说,未来人们在飞机、高铁上流畅接入互联网、收看4K超高清节目就靠天上的高通量通信卫星来实现。
一大拨守望家园的卫星即将来袭
今年,还有一大拨应用新技术、具备新技能的新卫星将相继升空,它们用自己的点点星光,守望地球上人们的幸福生活。
观天象知冷暖的风云气象卫星家族有望添丁;硬X射线调制望远镜卫星预计今年升空;被称为“张衡一号”的首个电磁监测试验卫星预计下半年发射,将使中国成为唯一拥有在轨运行的多载荷、高精度地震监测试验卫星的国家。
同时,中国商业航天发展迅速。今年,中国0.5米级高分辨率商业遥感卫星——高景一号将迎来两颗新星,随后4颗在轨的0.5米高分辨率光学遥感卫星将完成组网,实现全球任意地点每天重访一次。
今年,中国航天科工集团虹云工程的首颗技术验证星也将升空,该工程建成后,能让人们在世界任意角落接入互联网。
