Kusukela ngesikhathi salokho okubizwa ngokuthi “Umjaho Wendawo” phakathi kwe-United States nezwe elaliyiSoviet Union, isayensi iye yahamba ibanga elide. Ukukhishwa okukhethekile kuye kwasungulwa ngokuphelele futhi konke kunenjongo ethile: wembula izimfihlakalo ezintsha zesikhala.
Phezulu lapho, lapho umuntu namanje engakwazi ukufinyelela ngokukhululekile, kunamakhona amaningi angahloliwe. Njengoba indawo yonke iyinhlangano ebhekwa njengengapheli, umkhakha wokuphenywa mkhulu. Njengamanje, lokho okwaziwayo akulona ngisho isihloko sentaba yeqhwa futhi ukuya phambili, ukwethulwa komkhathi kuyithuluzi elikahle.
Ungase futhi ube nentshisekelo esihlokweni sethu: Ukufuna Okujulile Komhlaba Omusha: Hlangana namaplanethi lapho singathuthela khona!
Kungani ukwethulwa komkhathi kubalulekile? Thola manje!
Konke ukwethulwa komkhathi emlandweni kuveze imiphumela ekhiqizayo ekutholakaleni kwamakhona amasha omkhathi. Ngokuhamba kwesikhathi, amarokhethi asemkhathini athuthuke kwezobuchwepheshe, kube nesandla esikhulu ekwenzeni lezi mishini zibe yimpumelelo.
Khumbula ukuthi, ngokwethulwa komkhathi, isisekelo esibalulekile sazuzwa emashumini ambalwa eminyaka adlule. Ngazo, umuntu wakwazi ukunyathela ngempumelelo enyangeni, ebeka isibonelo esingokomlando esintwini. Kodwa ngokuqinisekile, kungani ukwethulwa komkhathi kubaluleke kangaka?
Bavumela ukubeka ama-probe, amarobhothi kanye nezibonakude emkhathini
Ukuhlola indawo yonke nendawo yonke bekungeke kufinyelele esiqongweni salokho ngaphandle kokwethuka komkhathi. Ngabo, ama-probes emkhathini, amarobhothi kanye nezibonakude zingathulwa ku-orbit, ekwazi ukunikeza umbono owandisiwe wezinto zasezulwini.

Njengoba eyimvelo engenabuhambi, ebandayo futhi edangele, umuntu akakakwazi ukungena ekujuleni kwakhe mathupha. Kodwa-ke, ngenxa yalolu hlobo lwezinto, kungenzeka ukuthintana nento ngayinye yendawo ebanjwayo.
Faka umuntu emkhathini
Ukusetshenziswa kwamarokhethi asemkhathini akwenzanga nje ukuthi kube nokwenzeka ukubeka unyawo enyangeni, kodwa futhi nokuthatha leso sisekelo kakhulu. Ngenxa yalesi sinyathelo esiyingqopha-mlando, kwaba nokwenzeka ukubeka izisekelo ze- Ukudalwa kwe-International Space Station yokuqala.
Ngale ndlela, umuntu uyakwazi ukuzinza endaweni ezungezile yoMhlaba, khona kanye emkhathini ongaphandle owuzungezile. Kusekuningi okusamele kwenziwe ukwedlula lokho obekucatshangwa, kodwa ngaphandle kokungabaza, lokhu okusunguliwe kusondeza isintu eqinisweni.
Thumela amasathelayithi okuxhumana emzileni womhlaba
Wake wazibuza yini ukuthi ukuphila komuntu bekuyoba njani ngaphandle kokuxhumana ngocingo? Hhayi-ke, iqiniso liwukuthi, isimo besingeke sifane namanje. Nokho, ngenxa yentuthuko yesayensi, iziphuphutheki zokwenziwa zazalwa, zaba yizicucu ezibalulekile ekudluliseni amasignali.
Lapho zithunyelwa emkhathini, ngayinye yazo inomsebenzi othile. Kodwa, ngokuvamile, bonke bahamba nomsebenzi wokudlulisa amaza esignali ukuxhumana nokudluliswa kwedatha.
Naka ukwethulwa kwakamuva kwerokhethi yasemkhathini!
ikhalenda ye NASA Ngokuqondene nezenzo ezizayo zasemkhathini, kusalokhu kugcwele izimanga. Ukuze uthole imininingwane ukwethulwa kwakamuva kwesikhala, ezintathu zazo ebezibalulekile zizoqanjwa.
Azenziwanga ezinyangeni zanamuhla, kodwa ziye zaba isibonelo sokuthi ubuchwepheshe buthuthukile. ukuba njengomlingiswa oyinhloko inkampani i-SpaceX ne-NASA, ukwethulwa kwamarokhethi asemkhathini kube isenzakalo esingavamile.
Qala umjaho oya ku-Mars nge-Falcon Heavy
Irokhethi yasemkhathini ekwazi ukuthwala amathani angaphezu kuka-60 wezinto zokusebenza, eyakhiwe ngaphansi kobuchwepheshe be-SpaceX obucwebe kakhulu. Ukuze uqale izigaba zokuhlola ukuthatha umuntu ku-Mars ngokuphepha esikhathini esizayo esiseduze.
Le rocket inenhloso, sondela ngangokunokwenzeka emzileni we-Mars, ukuthutha imoto kanokusho yohlobo lweTesla. Ngaphandle kokungabaza, konke kubukeka kukuhle ngokuzulazula kwe-aerospace.
I-rocket yasemkhathini emisha, i-Falcon-9
Ngokusebenzisana ne-SpaceX, le rocket yakhelwe ukusungula kabusha ngokuphelele ubunjiniyela nemishini yabo. Umsebenzi wobuciko inhloso yawo enkulu bekuwukusuka eMhlabeni ubheke eSiteshini Somkhathi Samazwe Ngamazwe.
I-Falcon-9 iyakwazi ukuthwala isisindo esimangalisayo futhi iphathwe kahle osomkhathi. Isici sayo esiyinhloko ukuthi uhlelo lwayo lokuphehla luvumela ukuphindela eMhlabeni, njengoba iqala, isenzakalo esingakaze sibonwe.
Impumelelo yekhepsuli yesikhala, i-Crew Dragon
Ukuze sithuthuke ngokuqondile ekuhloleni okujulile kwendawo yonke, i-SpaceX ngokubambisana ne-NASA, ikhuthaze ukwethulwa kwaleli khephu lesikhala. Ukusebenza kwayo nokusebenza kuzobeka isisekelo sokushintshwa izindleko ezinkulu ngamarokhethi asemkhathini.
Njengokungathi lokho akwanele, kufakazelwe ukuthi ingahanjiswa ngempumelelo ku-International Space Station. Ngale ndlela, ikhulisa kakhulu izindlela umuntu angaziyisa ngazo emkhathini.
Akukona konke kube yimpumelelo. Funda mayelana nokwethulwa kwerokhethi yasemkhathini okuhlulekile!
Ngempela, uma kuziwa ngokuya emkhathini, i umkhawulo wephutha uba mkhulu. Ukuze kuncishiswe lezi zingozi, ikakhulukazi ohambweni oluqhutshwa abantu, kungcono ukumemezela lezi zenzakalo njengokwethulwa kwerokhethi yasemkhathini okuhlulekile.

Izimo ezikahle azitholakali ngaso sonke isikhathi ukuze kwenziwe lezi zakhiwo, ngakho kuwukuhlakanipha ukugwema ukulimala okwengeziwe. Ukwethulwa kwerokhethi yasemkhathini okuhlulekile kubiza abaphathi bendawo izigidi zamaRandi futhi kufanele kulawulwe ngazo zonke izindleko. Kodwa-ke, ngezansi, uzofunda ngeminye yale micimbi edume kakhulu kulo nyaka.
Ukuqhuma kwe-SpaceX SN4
Ngaphandle kokwethulwa nokwethulwa, imodeli ye-SN4 yolayini oyimfihlo we-SpaceX wohambo lwasemkhathini yaqhuma esifundazweni saseTexas. Le rocket imiselwe ukuba ngowokuqala kwamarokhethi amaningi asebenziseka kabusha, ibanga elide kune-Falcon-9.
Izithiyo ku-Crew Dragon
Ngaleso sikhathi, i-SpaceX's Crew Dragon yabangela isiphithiphithi esikhulu ngenxa yecilongo eyayisikhala. Kodwa-ke, ukwethulwa kwayo kwakumele kumenyezelwe njengesehluleki, ngenxa yesimo sezulu esibi esasisondela. U-Elon Musk, umdali we-franchise, akakwazanga ukulahlekelwa enye yezibonelo zakhe ezinhle kakhulu.
