Tencent Technology News （ Qiao Hui ） Beijing time 6 month 1 Early morning 1 spot 23 About , take SpaceX
Two American astronauts of the Dragon spaceship have successively entered the International Space Station , Meet the astronauts waiting there .
More than two hours ago , Beijing time 5 month 31 day 22 spot 30 branch , The manned dragon spacecraft has just successfully docked with the International Space Station .
The two astronauts on the manned dragon flying ship are ： Douglas G Hurley （Douglas G. Hurley） And Robert L Bainken （Robert L. Behnken）, Born in
1966 Year and 1970 year .
Diagram note ： Astronauts bainken and Hurley （ right ）
They've all been in space three times , And they're all veterans of shuttle missions . among , Hurley has more than 683 Hours of experience , It's been done 2011 year 7
Last shuttle mission in June （ Code ：STS-135）. Bainken as a space shuttle mission expert , Have been executed successively 2008 Of （STS-123） and 2010
Of （STS-130） task , The accumulated time in space exceeds 708 hour , These include 37 Hours of spacewalk time .
The largest building in space ： The International Space Station
The total mass of ISS is 420 ton , long 109 rice , wide 73 rice , It's the largest building in space . Running about from the ground 400 Kilometers of low earth orbit , Speed is per second 7.6
The international space station is a modern scientific research facility , Large scale , Space laboratory for multidisciplinary basic and Applied Science Research , It provides a lot of experimental loads and resources for scientific experimental research in microgravity environment , Support for a long-term presence in earth orbit .
The international space station project was launched by 16 Countries build together , Operation and use , It's the largest ever , Space international cooperation projects that take the longest time and involve the most countries . since 1998
Since the official establishment of the station in , After more than ten years of construction , to 2010 Completed the construction task and transferred to the stage of full use in .
at present , The international space station is mainly composed of NASA , Russian National Space Corporation , European Space Agency , Japan Aerospace Research and development agency and Canadian Space Agency .
Fully automatic docking of manned spacecraft
before , We already know , Manned dragon ship belongs to SpaceX The second generation of dragon spacecraft （Dragon
2）, Ability to reuse . The second generation of dragon spacecraft can be divided into two types: manned dragon spacecraft and cargo dragon spacecraft , Its predecessor is the first generation cargo dragon spaceship （Dragon
1）. The new spacecraft can automatically dock with the space station , Not like the first generation , Need help from the robotic arm on the space station . of course , The manned dragon spacecraft also retains the option of manual docking .
The manned dragon spaceship used this time , diameter 4 rice , high 8.1 rice , Up to 7 Astronauts , It's the same number of astronauts that the space shuttle carries , Also with China 5 month 5
Daily tested “ A new generation of manned spacecraft ” Designed to carry the same number of astronauts .
How long will the two astronauts stay in space ? How to return ?
After the astronauts on the manned dragon flying ship entered the space station , Where to carry out the scheduled scientific tasks . Specific return date , There is no official statement at present , It's just that it won't be later 9 month 23
day . When the manned dragon spacecraft returns , Lose service first , Then slow down with the shield , After reaching a certain height , Then deploy the parachute to complete the final brake , Finally splashed down in the Atlantic Ocean .
