根据第四段中的 In low orbit,space debris circles around Earth at speeds between 7 to 8 kilometers per second. Because of the high speed,it can penetrate(穿透)the surface of the ISS.(在低轨道上,空间碎片以每秒7到8公里的速度围绕地球旋转。由于...
T he May 31 arrival of NASA astronauts Robert Behnken and Douglas Hurley onSpaceX's Crew Dragon was particularly exciting.T he Crew Dragon spacecraft, which ferried the NASA astronauts to the IS, lifted off on the Falcon 9 rocket from NASA's KennedySpace Center in Florida on May 30. T...
NASA currently expects to maintain the ISS through 2030, at which time it will have a SpaceX tug deorbit the station. However, this plan is dependent on the launch of commercial space stations, none of which have moved beyond the design stage. Tagged In International Space Station Space NA...

The International Space Station is aiding in the research of water purification technology. In the space station, scientists are able to conduct advanced experiments which are not possible on the Earth. In space, the external variables are significantly less compared to the Earth. Fewer constraints ...
A mission is expected to be launched in June of this year — sending three astronauts to orbit (巡航) for about three months, during which the life support system will be tested. China’s space station wont launch all at once; it will be assembled (组装) from several modules which will...
location you wish to know for ISS sighting opportunities and let the widget work its magic. It will tell you the time of the ISS flyover along with how long it is visible, the maximum height it will reach in the sky and which direction it will appear and disappear from your field of ...
current metal 3D printers are installed in a minimum ten square metre laboratory, “ he says. “To create the prototype for the ISS, we had to shrink the printer to the size of a washing machine”. This miniaturisation is needed in order to fit inside the rack in which the printer will...
WASHINGTON, Feb. 2 (Xinhua) -- NASA plans to retire the International Space Station (ISS) at the end of 2030, after which the ISS is expected to make a splash as it comes back to Earth, according to newly published plans. In its ISS Transition Report, NASA said that after the extensi...
The model was also used to be predicted the accumulated along the orbit of ISS galactic cosmic rays and inner radiation belt dose for 1 orbit (1.5 hours) and 4 consequences orbits (6 hours), which is the usual EVA continuation in dependence by the longitude of the ascending node of ISS....
