Icyiciro cyo guteranya gahunda ya sitasiyo y’ikirere ya Tiangong mu Bushinwa cyatangiye kuwa kabiri ubwo hatangizwaga icyogajuru cy’imizigo cya Tianzhou 4, nk’uko bivugwa n’ikigo gishinzwe iby’ikirere cy’Ubushinwa.

Icyogajuru cya robo cyarashwe saa saba n'iminota mirongo itanu n'itandatu za mu gitondo n'isasu rya Long March 7 ryaturutse mu kigo cya Wenchang Space Launch Center mu ntara ya Hainan, maze bidatinze cyinjiye mu nzira yo hasi y'Isi ifite uburebure bwa kilometero 400. Cyageze ku cyambu cya Tiangong muri iyo nzira saa mbiri n'iminota mirongo itanu n'ine za mu gitondo.

Itwaye hafi toni 6 z'ibinyabiziga n'ibikoresho, harimo n'amapaki arenga 200, Tianzhou 4 ifite inshingano zo gushyigikira ubutumwa bwa Shenzhou XIV buri hafi, aho biteganijwe ko itsinda ry'abantu batatu bazamara amezi atandatu muri sitasiyo ya Tiangong.

Wang Chunhui, injeniyeri mu kigo cy’astronaut mu Bushinwa witabiriye gahunda ya Tianzhou 4, yavuze ko imizigo myinshi y’ubwato igizwe n’ibikenerwa mu buzima bw’abakozi ba Shenzhou XIV, cyane cyane ibiryo n’imyambaro.

Kugeza ubu, Tiangong igizwe na Tianhe core module, Tianzhou 3 na Tianzhou 4. Abayirimo baheruka - abahanga mu by'ikirere batatu bo mu butumwa bwa Shenzhou XIII - barangije urugendo rw'amezi atandatu bagaruka ku Isi hagati muri Mata.

Icyogajuru cya Shenzhou XIV kizatangizwa mu kwezi gutaha kiva mu kigo cya Jiuquan Satellite Launch Center mu majyaruguru y'uburengerazuba bw'Ubushinwa, nk'uko byatangajwe na Hao Chun, umuyobozi w'ikigo gishinzwe iby'ikirere, mu kwezi gushize.

Muri Nyakanga, igice cya mbere cya sitasiyo ya Tiangong, Wentian (Quest for the Heavens), kizatangizwa, naho icya kabiri, Mengtian (Dreaming of the Heavens), kizoherezwa ku cyambu cya sitasiyo mu Ukwakira, nk'uko Hao yabitangaje. Nyuma yo guhuzwa na Tiangong, sitasiyo izakora imiterere isa na T.

Nyuma y’aho ikigo cy’indege gikorera, ubwato bw’imizigo bwa Tianzhou 5 hamwe n’itsinda rya Shenzhou XV biteganijwe kugera ku birindiro binini bizenguruka mu mpera z’umwaka, nk’uko uyu muyobozi yabitangaje.

Tianzhou 1, icyogajuru cya mbere cy’imizigo mu Bushinwa, cyarashwe giturutse mu kigo cya Wenchang muri Mata 2017. Cyakoze ingendo nyinshi zo gupakira no kongeramo lisansi mu kirere hamwe na laboratwari y’Abashinwa mu kirere mu nzira yo hasi y’Isi hagati ya Mata na Nzeri muri uwo mwaka, bituma Ubushinwa buba igihugu cya gatatu gishobora kongeramo lisansi mu kirere, nyuma y’icyahoze ari Leta Zunze Ubumwe z’Abasoviyeti na Leta Zunze Ubumwe za Amerika.

Ifite ubuzima bwagenwe bwo kumara igihe kirenga umwaka, buri cyogajuru cya Tianzhou gifite ibice bibiri - icyumba cy’imizigo n’igice cyo kuyiyobora. Imodoka zifite uburebure bwa metero 10.6 na metero 3.35 z’ubugari.

Iyi modoka itwara imizigo ifite uburemere bwa toni 13.5 kandi ishobora gutwara toni zigera kuri 6.9 z'ibikoresho bijyanwa muri sitasiyo y'ikirere.
