Bureau of American spaceflight aviation (NASA) station of this space of Zhou Xiangguo time issues a statement, the astronaut on requirement space station will weigh 2.9 tons lade the goods of useless old batteries dish send orbit, NASA expresses, this is the heaviest object that throughout history discards from international space station, the aerospace rubbish that predicts to discard this will advance in aerospace 2-4 year time, earthly aerosphere is entered to burn later.
Last year May when, the 9th also is supply of last Japan HTV batteries of naval vessel general is locomotive implement carry international space station, the freight tray that and will be carried uses stays in dimensional station, when tray arrives at a space to stand, 6 new lithium ion battery were carried above. These 6 batteries are on the power source frame work that international space station had received repeatedly in a year in the past.
HTV freight airship is by bureau of Japanese aerospace exploration (JAXA) stand technically for international space (ISS) plan research and development, weigh what labour makes not to carry person freight aircraft by 3 water chestnut. Came 2017 between 2020, HTV freight airship the lithium ion power that 4 times the task carried 24 to upgrade to international space station stores device. The arrival of these batteries, replaced eventually had used 48 years already the nickel hydrogen batteries of ageing. After old batteries is taken out, not be direct processing, should find a place for them however go up in freight tray, put dimensional course next.
As one used to do moment, these tray are gone back and forth between inside the cabin of HTV freight airship by installation the space stands, the mechanical arm that the space stands can finish the tray that disassemble and reinstalls freight airship. When HTV leaves a space to stand, they are entered south Pacific Ocean the aerosphere in the sky, in the aerosphere time that enters that place, the hardware part of spacecraft batteries is most by burn down, a few fragments that leave can drop into the more out-of-the-way place on Pacific Ocean.
After HTV freight airship undertook the 9th times carriage the mission, will be retired, from in the past be informed in a few reports, bureau of Japanese aerospace exploration (JAXA) developing next generation to upgrade the aerospace freight airship of edition, name HTV-X. Because HTV freight airship retires, bring about the goods that reassume is answered and cannot handle the last time to be carried tray and replace the useless old batteries that come down, accordingly these " aerospace rubbish " will be sent into orbit, and be in predict 2 earthly aerosphere is returned after arriving 4 years, burn in aerosphere, won't cause pollution finally to the earth.
