中国神舟十四号载人飞船下月发射
5/09/2022
根据央视网消息，神舟十四号载人飞船今年6月将发射，三名航天员将进入中国空间站组合体，并在轨驻留六个月。
此外，今年年内，中国空间站也将完成在轨建造。
中国载人航天工程办公室主任郝淳上月表示，根据任务计划安排，今年将实施六次飞行任务，除了神舟十四号发射外，其他五次任务分别为：今天刚刚发射的天舟四号货运飞船；7月发射空间站问天实验舱，与天和核心舱对接；10月发射梦天实验舱与核心舱对接，之后空间站三舱形成“T”字基本构型，完成中国空间站在轨建造；以及将发射天舟五号货运飞船和神舟十五号载人飞船，神舟十五号飞行乘组由三名航天员组成，与神舟十四号航天员在轨轮换后，在轨驻留6个月。
神舟十三号载人飞船上月已完成全部任务，返回着陆场。三名执行任务的航天员翟志刚、王亚平、叶光富也结束了为期六个月的太空之旅。
据报道，三名航天员的返回，也意味着中国空间站关键技术验证阶段圆满收官。
据了解，建造空间站，解决有较大规模的、长期有人照料的空间应用问题，是中国载人航天工程“三步走”发展战略中第三步任务目标。
2021年以来，中国载人航天工程已成功实施空间站关键技术验证阶段的五次飞行任务，神舟十三号飞行任务是第六次，也是这一阶段的最后一次。
中国天舟四号货运飞船成功发射并与空间站交会对接
5/09/2022
据中国载人航天工程办公室消息，搭载天舟四号货运飞船的长征七号遥五运载火箭今天（5月10日）凌晨1时56分，在中国文昌航天发射场点火发射，约10分钟后，飞船与火箭成功分离，进入预定轨道，2时23分，飞船太阳能帆板顺利展开工作，发射成功。
天舟四号货运飞船入轨后顺利完成状态设置，于8时54分采用自主快速交会对接模式，成功对接空间站天和核心舱后向端口。
根据科技日报报道，这是中国载人航天工程的第22次发射任务，是空间站建设从关键技术验证阶段转入在轨建造阶段的首次发射任务，也是长征系列运载火箭的第420次飞行。
据了解，航天员要在空间站长期驻守，吃、穿、用，乃至呼吸所需的物资，都要由货运飞船及时送到空间站，空间站维持正确轨道所需的燃料也靠货运飞船送达。要将载有大批物资的货运飞船按时送入太空，就必须有运力足、“力气”大、可靠性高的运载火箭。
据悉，执行天舟四号发射任务的长征七号遥五运载火箭是由中国航天科技集团一院抓总研制，它是中国新一代中型液体运载火箭，也是专门为建造空间站、发射货运飞船而研制的运载火箭，所以它也被称作载人航天的“货运专车”。
长征七号遥五运载火箭总长53.1米，捆绑了4个助推器，起飞重量接近600吨，运载能力达到13.5吨。同时，该运载火箭还是个“钢筋铁骨”的大个子，体重几百吨，体重的90%甚至更多都是燃料。

中国载人航天工程办公室宣布，天舟三号货运飞船入轨后顺利完成入轨状态设置，于20日22时08分，采用自主快速交会对接模式成功对接于空间站天和核心舱后向端口。整个过程历时约6.5小时。
据中新社报道，天舟三号装载了航天员生活物资、舱外航天服及出舱消耗品、空间站平台物资、部分载荷和推进剂等，与天和核心舱及天舟二号组合体完成交会对接后，转入三舱(船)组合体飞行状态。
搭载天舟三号货运飞船的长征七号遥四运载火箭昨天15时10分在文昌航天发射场点火发射。约597秒后，飞船与火箭成功分离，进入预定轨道。15时22分，飞船太阳能帆板顺利展开且工作正常。

China successfully launches Tianzhou-3 for second space station supply mission; to support upcoming six-month Shenzhou-13 manned mission

Knock knock. This is your delivery-man Tianzhou-3, and please confirm your package receipt and may you have a happy Mid-Autumn Festival!
Carrying the Tianzhou-3 cargo spacecraft, the Long March-7 Y4 rocket lifted off from Wenchang Space Launch Center located in South China’s Hainan Province on Monday afternoon, one day ahead of this year’s Mid-Autumn Festival – one of the happiest family reunion holidays for the Chinese people.
The lift-off gave the nearby forest of palm trees quite a shake in the Hainan tropical haze, the same way it excited many who came to witness the historic moment at the Wenchang beach on Monday afternoon.
As the fourth of 11 missions scheduled to build China’s three-module space station, Tianzhou-3 mission came shortly after the historic Shenzhou-12 mission in which three taikonauts spent a record 90 days in the China’s space station core module and safely returned to Earth on Friday.
After a flight time of around 597 seconds, the spacecraft separated with the rocket and entered preset orbit. At 3:22 pm, the solar panels onboard the spacecraft smoothly unfolded, with all functions in normal operating condition, marking the success of the third launch of a spaceship to the space station core cabin, according to the China Manned Space Agency (CMSA.)
The Monday mission is tasked to bring supplies, equipment and propellant to get Tianhe ready for the next three-taikonaut Shenzhou-13 mission in October for their six-month stay. It is the Tianzhou spacecraft series second supply delivery run to the orbiting Tianhe module following a first by the Tianzhou-2 mission launched on May 29.

据中国载人航天工程办公室消息，北京时间2021年9月20日15时10分，搭载天舟三号货运飞船的长征七号遥四运载火箭，在中国文昌航天发射场点火发射，约597秒后，飞船与火箭成功分离，进入预定轨道，15时22分，飞船太阳能帆板顺利展开且工作正常，发射取得圆满成功。
后续，天舟三号货运飞船将与在轨运行的空间站组合体进行交会对接。这是中国载人航天工程的第20次发射任务，也是长征系列运载火箭的第 389次飞行。
Although the launch of Tianzhou-2 by Long March-7 Y3 rocket was a successful one, it experienced two delays and met problems of leaking of injected fuels.
The Tianzhou-2 cargo spacecraft was originally slated to be launched at around 1:30 am on May 20 and to head to China’s Tianhe space station core cabin, which was launched into orbit on April 29, for a supply run. However, the launch was scrubbed narrowly following an announcement from CMSA on the early morning of May 20 for “technical reasons.”
Research teams were dispatched immediately to check system functions, while the command center prepared for an attempt to recover the mission, which had been set to a day later in the early morning of May 21. However, after liquid oxygen was refueled eight hours before the scheduled launch time, abnormal signals once again occurred.
Drawing lessons from the previous launch, the Long March-7 rocket developer with the China Academy of Launch Vehicles have further optimized the quality examination process before and after the lift-off and make detailed emergency plans. This is to ensure the launch mission is on time with zero errors, the academy told the Global Times on Friday.
To sustain Taikonauts’ longer stay in space
Global Times learned from the mission insiders that Tianzhou-3 mission will lay ground for the upcoming October Shenzhou-13 mission, just the way Tianzhou-2 mission prepared for the epic Shenzohu-12 manned spaceflight mission. The October mission is expected to last six months, renewing the record of the longest stay in space for a Chinese astronaut in a single mission.
The spacecraft developer China Academy of Space Technology (CAST) told the Global Times in a statement that just like the Tianzhou-2, Tianzhou-3 will carry a range of goods including daily necessities, drinking water, gas supplies, consumables for extravehicular activities [spacewalk,] as well as experiment payloads.
Yang Sheng, Chief designer of the Tianzhou-3 spacecraft system, told the Global Times that “As Tianzhou-3 mission will sustain taikonauts’ 6-month-long stay in space, the density of cargo is greater on Tianzhou-3 than on Tianzhou-2, and Tianzhou-3’s loading capability is also higher than that of Tianzhou-2. The number of packages onboard Tianzhou-3 is 25 percent more than on Tianzhou-2.”
There were 6.8 tons of supplies onboard the Tianzhou-2, including some 160 parcels of goods and two tons of propellants, CAST told the Global Times previously.
One of the most expensive items to be onboard the Tianzhou-3 would be one piece of spacesuit specially designed for spacewalk missions that weighs some 90 kilograms, the CAST highlighted in the Friday statement. Tianzhou-2 had sent two pieces of spacesuits for Taikonauts’ spacewalk with each weighing some 100 kilograms.
Also, onboard Tianzhou-3 is the replacement parts of the urine treatment system to ensure the device is in the best condition for the Shenzhou-13 crew, Global Times learned from the system developer 206 Research Institute of the Second Academy of the China Aerospace Science and Industry Corp (CASIC).
“The system has processed some 600 liters of urine into over 500 liters of water which was used to generate oxygen and for clean-up purpose during the Shenzhou-12 crew’s three-month stay. Shenzhou-13 crew will install those parts when moving into the China’s space station core module,” Cui Guangzhi, the project leader, told the Global Times.
The Tianzhou-3 cargo spacecraft is expected to also execute a fast and automatic rendezvous and docking with the Tianhe core module, just like the Tianzhou-2 spacecraft did in May, which took some eight hours after lift-off,according to Deng Kaiwen, assistant of the Tianzhou-3 cargo spacecraft’s chief commander from the spacecraft developer
Compared to the Tianzhou-1’s rendezvous and docking with Tiangong-2 in 2017, which took about two days, Tianzhou-2 took a mere eight hours to achieve the feat in May.
Tianzhou-3 will dock to the Tianhe module from the rear. Before such development, CMSA updated on Saturday, Tianzhou-2 had flown around Tianhe and conducted an automatic docking to the craft’s front, which took four hours.
Shenzhou-13 will later rendezvous with the Tianhe module and conduct a R-Bar or vertical docking with the orbiting craft, which Shenzhou-12 had practiced on Friday before heading back to Earth.

天舟三号满载出发，它都带了啥？
科技日报记者 付毅飞

9月20日，由中国航天科技集团五院抓总研制的天舟三号货运飞船在海南文昌发射场成功发射。按计划安排，它将与空间站核心舱和天舟二号组合体实现自主快速交会对接。
记者从五院了解到，天舟三号任务是空间站关键技术验证及建造阶段的第二次货物运输应用性飞行。飞船为满载状态，运载了可支持3名航天员6个月在轨驻留的物资，以及空间站备份设备、空间科学载荷等，还携带了补加推进剂等上行物资。该飞船还具备并网供电能力，在停靠期间可以为空间站提供供电支持。
“天舟三号携带的货物主要包括航天员生活物资、航天饮水、气体补给、卫生用品、应急储备物资、出舱消耗品、维修备件和实验载荷等，与天舟二号基本一致。”五院天舟三号总指挥冯永介绍说。
航天员在空间站内生存需要适宜的大气环境，所以天舟三号运送的一样重要的货物，就是气瓶。这种气瓶用特种复合材料制成，可以充至300倍大气压力，1瓶氧气就能供航天员很长时间使用。
除了空气，太空生活也离不开宝贵的水资源。五院货运飞船系统总体主管设计师王冉介绍，天舟三号这次带了多组水箱，供航天员饮用和使用。这些水箱均采用了轻质、柔软材料制成的“水囊”包装，不仅可以保证饮水安全，还可以在饮水用尽后更好地收纳。
此次货物中最贵重的，要属舱外航天服了。该装备重达90多公斤，价格达到千万元量级，堪称世界上最贵的“衣服”。货运飞船系统为此专门设计了舱外服支架，保证其在运输过程中不会损坏。
除了上述特殊物品，天舟三号携带的大多数货物都是用标准化、型谱化货包装载的。这些货包不仅具有良好的力学承载性能，还有抗菌、防霉、阻碍燃烧、无有害气体挥发等多个优点。鲜为人知的是，这些货包材料的灵感竟源于螃蟹壳。王冉介绍，研制人员从螃蟹壳里提取了一种特有成分，经过特殊工艺，特殊制作，研发出性能优异的货包材料。
在货物装载方面，天舟三号充分继承了天舟二号的经验，并进行了优化和改进。五院天舟三号货运飞船系统总体主任设计师杨胜表示，相比天舟二号，天舟三号货物装载的密度更大，货物在发射场安装的效率更高。由于天舟三号所运物资要满足航天员6个月的使用需求，对整船装载能力提出了更高要求，装载的货包数量相比天舟二号增加了25%。
