Uma sicabangela lesi sigaba esiphathelene neMercury Seven. Obani abangazange baphile baze bathole umhlalaphansi futhi iyini imbangela yokufa kwabo?
Context:I-Mercury Seven kwakuyiqembu labahambi ngezindiza abayisikhombisa abakhethwa ukuba bayise umkhumbi-mkhathi weProject Mercury. Babizwa nangokuthi i-Original Seven ne-Astronaut Group 1. Amagama abo amenyezelwa obala yi-NASA ngo-April 9, 1959; la ma-astronaut ayisikhombisa aseMelika ayengoScott Carpenter, uGordon Cooper, uJohn Glenn, uGus Grissom, uWally Schirra, u-Alan Shepard, noDeke Slayton. I - Mercury Seven yavula umsebenzi omusha e - United States, futhi yasungula isithombe somkhumbi - mkhathi wase - America emashumini eminyaka alandelayo.  Ekugcineni, wonke ama-Mercury Seven andizela emkhathini. Bahamba ngezindiza eziyisithupha zezinhlelo zeMercury ezazinomkhumbi-mkhathi kusukela ngoMeyi 1961 kuya kuMeyi 1963, futhi amalungu eqembu andiza kuzo zonke izinhlelo ze-NASA zokuhamba ngomuntu emkhathini ngekhulu lama-20 <unk> iMercury, iGemini, i-Apollo, ne-Space Shuttle.  UShepard waba owokuqala waseMelika ukungena emkhathini ngo-1961, futhi kamuva wahamba phezu kweNyanga e-Apollo 14 ngo-1971. UGrissom wandiza ohambweni lokuqala lweGemini ngo-1965, kodwa washona ngo-1967 emlilweni we-Apollo 1; abanye bonke basinda ngemuva kokuthatha umhlalaphansi. UShirra waba yilungu le-Apollo 7 ngo-1968, okwakuwumsebenzi wokuqala we-Apollo owawuhamba nabantu, esikhundleni sikaGrissom. USlayton, owayengakwazi ukuhamba emhlabeni ngenxa yokushaya kwenhliziyo, wagcina esendiza eMkhakheni Wokuhlola i - Apollo - Soyuz ngo - 1975. UGlenn waba owokuqala waseMelika ukuzungeza umkhathi ngo-1962, futhi ngo-1998 wahamba ngomkhumbi-mkhathi i-Space Shuttle Discovery ukuze abe umuntu omdala kunabo bonke abake baya emkhathini ngaleso sikhathi eneminyaka engu-77. Wayeyilungu lokugcina eliphilayo leMercury Seven ngesikhathi eshona ngo-2016 eneminyaka engu-95.
NguGus Grissom kuphela ongazange aphile aze athathe umhlalaphansi. Bonke abanye basinda ngemva kokuthatha umhlalaphansi. Imbangela yokufa kwakhe iwumlilo we-Apollo 1.
