intshayelelo
Abantwana banomdla esibhakabhakeni kuba ngumxholo onika umdla. Idala umdla kunye nomdla phakathi kwethu xa sisiva malunga nomsebenzi wasemajukujukwini okanye oosomajukujuku ababhabhela emajukujukwini. Ezingqondweni zethu, kukho imibuzo emininzi.
Ekundulukeni, ingaba isantya esingakanani koosomajukujuku? Xa udada ngaphandle kobunzima esithubeni, uziva njani? Injani indawo yokulala koosomajukujuku? Zitya njani? Xa uwujonga usemajukujukwini, ukhangeleka njani uMhlaba? Kwesi sincoko sisemajukujukwini, uya kufumana iimpendulo kuyo yonke le mibuzo. Ukufumana ukuqonda okunzulu kwendawo, abafundi kufuneka bayifunde.
Amagama angama-50 esincoko esikwiSithuba
Isithuba yindawo engaphandle komhlaba. Iiplanethi, iinkwenkwezi, iinkwenkwezi nezinye izinto ezisesibhakabhakeni zifumaneka emajukujukwini. Iimeteors zizinto eziwa esibhakabhakeni. Kuthe cwaka kakhulu esithubeni. Ukuba ukhwaza ngokwaneleyo esithubeni, akukho mntu uya kukuva.
Umoya awukho esithubeni! Hayi indlela ekuya kuba yinto engaqhelekanga ngayo oko! Ewe ngokunjalo! Ngokusisiseko, yinto nje engenamsebenzi. Akukho maza asandi anokuhamba kwesi sithuba yaye akukho kukhanya kwelanga kunokusasazeka kuso. Ingubo emnyama ngamanye amaxesha inokugquma indawo.
Kukho ubomi obuthile esithubeni. Iinkwenkwezi kunye neeplanethi zohlulwe ngumgama omkhulu. Irhasi nothuli zivala esi sikhewu. Izidalwa zasesibhakabhakeni zikwakho nakwamanye amakroza. Zininzi zazo, kuquka nesijikelezi-langa sethu.
Amagama angama-100 esincoko esikwiSithuba
Isandi sesikhalo sakho asivakali esithubeni. Ivacuum esithubeni ibangelwa kukungabikho komoya. Ivacuum ayikuvumeli ukwanda kwamaza esandi.
Umgama oziikhilomitha ezili-100 ujikeleze isijikelezi-langa sethu uphawula ukuqala “kwendawo engaphandle”. Isithuba sibonakala njengengubo emnyama egcwele iinkwenkwezi ngenxa yokungabikho komoya wokusasaza ukukhanya kwelanga.
Kukho inkolelo eqhelekileyo yokuba indawo ayinanto. Nangona kunjalo, oku akuyonyani. Izixa ezikhulu zerhasi esasazeke kancinci kunye nothuli luvala izithuba ezinkulu phakathi kweenkwenkwezi kunye neeplanethi. Amakhulu ambalwa eathom okanye iiathom kwi-cubic meter nganye inokufumaneka nakwezona ndawo zingenanto zesithuba.
Imitha esemajukujukwini inokuba yingozi koosomajukujuku ngeendlela ezininzi. Imitha yelanga ngowona mthombo omkhulu wemitha ye-infrared kunye ne-ultraviolet. I-X-reyi enamandla amakhulu, i-gamma ray, kunye nesuntswana le-cosmic ray inokuhamba ngokukhawuleza njengokukhanya ukuba ivela kwinkqubo yeenkwenkwezi ezikude.

Abantu belizwe lethu bebesoloko bethabathekile zizinto ezinxulumene nendawo. Kuphela kwaba yintelekelelo namabali awathi umntu wayenokuphupha ehamba esibhakabhakeni ngoxa kwakungenakwenzeka kwaphela ukwenjenjalo.
Ukuhamba emajukujukwini kuyenzeka ngoku
De kwayinkulungwane yamashumi amabini, le ndoda yaba nempumelelo ephawulekayo kuphando lwasemajukujukwini, nto leyo eyenza eli phupha libe yindlela elula.
I-Indiya ikhule kakhulu kwisayensi kwinkulungwane yama-21 kangangokuba iimfihlakalo ezininzi zendawo ziye zasonjululwa lilizwe. Ukongezelela, ukutyelela inyanga kulula kakhulu ngoku, nto leyo eyayiliphupha labaninzi kwakudala. Njengenqaku elisecaleni, i-spaceflight yabantu yaqala ngo-1957.
Ubomi bokuqala kwiSithuba
I-'Layaka' yathunyelwa emajukujukwini okokuqala ngqa ngesi sithuthi ukuze iphonononge indlela isithuba esizichaphazela ngayo izilwanyana.
Isiphekepheke esibizwa ngokuba yi<em>Explorer saphehlelelwa yiUnited States of America ngoJanuwari 31, 1958, sinika elinye iwonga kwihlabathi lezemajukujuku.
Indawo enkulukazi yamagnetic ngaphezulu koMhlaba yayiza kufunyanwa ngesi sithuthi, kunye neziphumo zayo kuMhlaba uphela.
Umkhweli wokuqala
Imbali yethu yophando lwasemajukujukwini ikhunjulwa ngesiganeko sangoJulayi 20, 1969. UNeil Armstrong kunye noEdwin Aldrin baba ngabantu baseMelika bokuqala ukubeka unyawo enyangeni ngolu suku.
Ehleli kwisiphekepheke esinegama elithi 'Apollo-11', wafika kumphezulu wenyanga. Umkhweli wesithathu kwesi siphekepheke yayinguMichael Collins.
Wathi, “Yonke into intle” ukufika kwakhe okokuqala enyangeni. Ngale nto, waba ngumntu wokuqala emhlabeni owahlala enyangeni.
Isiphelo,
Ngekwakungenakwenzeka ukuba ucinge ukuba ixesha lokhenketho lwasemajukujukwini nalo liza kufika kwixesha elizayo emva kokufika kwexesha lasemajukujukwini. Umkhenkethi wokuqala wasemajukujukwini ehlabathini yayinguDennis Tito waseIndiya ngo-2002.
