Day boat first, which this year will dock with the temple on the second of three
In last year's October 11th Temple on the second Shenzhou spacecraft completed a space rendezvous and docking Assembly flight for a month. Bai m sh, Chief Architect, said, this year, day boat three times, first with the temple on the second rendezvous and docking.
Days after the boat is launched into orbit a spacecraft will be docked for the first time with the temple on the second.
Space technology group five hospital days boat first, freight spacecraft total designer Bai m sh: days boat first, basically is (launches God) two days (Hou), (for) rendezvous docking, with Temple second, formed combination body, whole of time probably two months, two months of early docking completed yihou, first for a State of check, completed yihou on for advance agent of fill added.
Following the completion of the first rendezvous and docking, day boat, first through a combination of temple on the second of two months in orbit, propellants in orbit completed additional testing, and testing of cargo ships on the combination control. After the completion of this phase, a spacecraft out of temple on the second boat, on the other side of the second docking with the temple on the second.
After he finished his flying test, days the boat is first separated from the temple on the second again, two aircraft independent flights for three months, during which time, day boat first, mainly carrying space scientific experiments. At the end of these three months, day boat first to dock with the temple on the second to last, verify that independent quick docking requires two spacecraft docked in about 6 hours to achieve.
Boat first for the temple on the second day air and Canada oil
The day boat first cargo ship, one of the most important tasks, that is, and is running in the space of "temple on the second" space laboratory for rendezvous and docking, verify that adding technology the propellants in orbit. This technology also follow Chinese-built space station one of the most critical technologies. So, "space filling" what is the difference and we usually cheer on land?
Days after the ship first docked with the temple on the second, through the gas pressure between the two spacecraft, aboard the boat a propellant from the day a steady stream into the temple on the second, although it looks and almost on the ground, but to realize, is not always easy.
Space technology group five hospital days boat first, freight spacecraft total designer Bai m sh: both guarantee it can accurate of docking, and can meet sealed of requirements, advance agent is is cannot leak of, such words floating broken received device is can floating of, two a docking institutions docking Shang certainly is has must of deviation of, we through floating to elimination this deviation of effect, achieved accurate of docking.
Because these technologies have no way to simulate the ground, must be hands-on in the space environment, in order to test the reliability of the technology, and it also gives the "day boat first" more arduous tasks.
"Express little brother" temple on the second to send material
By around 2020, China will build the first Chinese space station. Future astronauts on long working life of the space station will have to reserve a large amount of material, this would have been done by a cargo ship. Then China's first cargo spacecraft "day boat first," this is God's "express little brother," it wants to sent to the temple on the second is what?
Days the boat is first charged with verification of future space station supplies transportation tasks, what can be shipped and what cannot be shipped, what changes will happen in the process of transporting goods, these were all one by one to verify, so this day shipments are on the boat, a real "real thing".
Aerospace Science and Technology Corporation five days the boat is first cargo spacecraft designer Bai m sh: astronauts, for example, supplies, including food and clothing live in these things, and out-of-class outerwear, as well as drinking water, special tanks, by transport boat, first mount and see whether our ships meet the requirements of different goods carriers.
Use of a boat is a boat of a spacecraft features, in addition to shipping, it can also be equipped with test equipment. On the day boat, carrying a total of 40 pieces of equipment, to 13 tests in space. Equipment can be installed in the cargo inside the warehouse or hanging outside of the hull, which improves space utilization and best meet the needs of different tests.

天舟一号今年将与
天宫二号进行三次对接
在去年的10月份，天宫二号与神舟十一号飞船完成了一次太空交会对接，进行了一个月的组合体飞行。总设计师白明生说，今年，天舟一号将与天宫二号进行三次交会对接。
天舟一号飞船发射进入轨道之后，将与天宫二号进行首次对接。
航天科技集团五院天舟一号货运飞船总设计师 白明生：天舟一号基本上是（发射上天）两天（后），（进行）交会对接，跟天宫二号形成组合体，整个的时间大概两个月，两个月的前期对接完成以后，首先进行一个状态的检查，完成以后就进行推进剂的补加。
在完成首次交会对接之后，天舟一号与天宫二号组成的组合体将进行两个月的在轨飞行，完成推进剂在轨补加试验，同时测试货运飞船对组合体的控制能力。这一阶段任务完成之后，天舟一号飞船撤离天宫二号，从另一侧与天宫二号进行二次对接。
完成绕飞试验以后，天舟一号就与天宫二号再次分离，两个飞行器将独立飞行三个月，这期间，天舟一号主要完成搭载的空间科学试验。而在这三个月的末期，天舟一号还要与天宫二号进行最后一次对接，验证自主快速交会对接技术，要求两个航天器在6个小时左右实现对接。
天舟一号将为天宫二号空中国和加拿大油
本次天舟一号货运飞船最重要的一项任务，就是与正在太空运行的“天宫二号”空间实验室进行交会对接，验证推进剂在轨补加技术。而这项技术也是后续中国建造空间站最为关键的技术之一。那么，“太空加油”和我们平时在陆地上加油有什么不同？
天舟一号与天宫二号对接之后，通过两个航天器之间产生的气体压力，把推进剂从天舟一号上源源不断输送到天宫二号上，虽然看起来和地面加油差不多，但是要真正实现起来，却并不容易。
航天科技集团五院天舟一号货运飞船总设计师 白明生：既要保证它能准确的对接，又能满足密封的要求，推进剂一点是不能漏的，这样的话浮动断接器是可浮动的，两个对接机构对接上肯定是有一定的偏差的，咱们通过浮动来消除这个偏差的影响，实现准确的对接。
由于这些技术在地面没有办法模拟实现，所以必须要在太空环境中实际操作，才能够检验技术的可靠性，而这也赋予了“天舟一号”更艰巨的任务。
“快递小哥”要往天宫二号送物资
到2020年左右，中国将建成第一个中国人的空间站。未来航天员在空间站长期工作生活就必须储备大量的物资，这个就得由货运飞船来完成了。那么，中国的第一艘货运飞船“天舟一号”，这个即将上天的“快递小哥”，它要给天宫二号送的都是什么呢？
天舟一号担负着验证未来空间站物资的运输任务，什么能运什么不能运，运送的过程货物会发生怎样的变化，这些都是需要一一验证的，所以这次天舟一号上运送的可都是实实在在的“真家伙”。
航天科技集团五院天舟一号货运飞船总设计师 白明生：比如说航天员的生活物资，包括吃穿用住的这些东西，还有出舱的舱外服，还有饮用水，专门的有水箱，通过天舟一号的运输装载，看看我们这个船是不是满足不同货物运载的要求。
一船多用是天舟一号飞船的一大特点，除了运货，它还可以搭载试验设备。此次天舟一号上总共搭载了40台设备，要进行13项太空试验。设备可以装在货物仓内部或悬挂在船体外侧，这样既提高了空间利用率，也最大程度满足了不同试验的需求。
