Space Co­op­er­a­tion

Beijing Review - - This Week Society -

China an­nounced that all UN mem­ber states are wel­come to jointly uti­lize its fu­ture China Space Sta­tion (CSS) on May 28.

“The CSS be­longs not only to China, but also to the world,” said Shi Zhongjun, China’s Am­bas­sador to the UN and Other In­ter­na­tional Or­ga­ni­za­tions in Vi­enna.

“All coun­tries, re­gard­less of their size and level of de­vel­op­ment, can par­tic­i­pate in the col­lab­o­ra­tion on an equal foot­ing,” he said.

In­ter­ested pub­lic and pri­vate or­ga­ni­za­tions, in­clud­ing in­sti­tutes, academies, uni­ver­si­ties and pri­vate en­ter­prises with sci­en­tific ori­en­ta­tions, can iden­tify their ap­pro­pri­ate mod­els of co­op­er­a­tion on board the CSS, whether it’s the growth of a space plant or the ac­com­mo­da­tion of an as­tro­naut, said the am­bas­sador.

The CSS, which is ex­pected to be launched by 2019 and be com­pleted and op­er­at­ing by 2022, will be the world’s first space sta­tion that is built by a de­vel­op­ing coun­try.

Con­sist­ing of one core mod­ule and two ex­per­i­men­tal mod­ules, the CSS will have the ca­pac­ity to ac­com­mo­date up to three as­tro­nauts at a time and a max­i­mum of six in ro­ta­tion.

Op­er­at­ing in low Earth or­bit about 400 km above the Earth’s sur­face, the CSS will be used in a wide range of re­search fields, in­clud­ing space medicine, life science, biotech­nol­ogy, mi­cro­grav­ity science, Earth science and space tech­nol­ogy. days in the 13 cities in the re­gion, up 2.2 per­cent­age points year on year, min­istry data showed.

The den­sity of PM2.5 (air­borne par­ti­cles smaller than 2.5 mi­crons in di­am­e­ter), a key in­di­ca­tor of air pol­lu­tion, dropped 18.8 per­cent year on year dur­ing the same pe­riod, while the den­sity of PM10, an­other ma­jor pol­lu­tant, fell 12.9 per­cent.

Bei­jing saw the ra­tio of good air qual­ity days in­crease by 3.9 per­cent­age points to 64.7 per­cent in the pe­riod, with PM2.5 and PM10 den­sity down 22.4 per­cent and 9.9 per­cent, re­spec­tively.

Na­tion­wide, 338 cities had an av­er­age of 76.7 per­cent days with good air qual­ity days, up 0.9 per­cent­age points year on year.

How­ever, in April, air qual­ity got worse in the Bei­jing-Tian­jin-He­bei re­gion. The av­er­age amount of days with good air qual­ity was 58 per­cent, down 13.7 per­cent­age points from April last year, with lower PM2.5 den­sity but higher PM 10 den­sity.
