Whakarāpopototia te tuhinga:  Kua whakapuakina e United Launch Alliance ngā mahere nui hei whakarewa i tētahi pūkaha ka taea te whakamahi anō i te ingoa 'Vulcan' i te tau 2019. Ka whakamahi a Vulcan i ngā pūkaha hōu, i te whakaora i waenganui o te rangi, me tētahi atamira hōu o runga e whai ana ki te āhei i ngā mahi matatini i runga i te aorangi. Te āhua nei kua whakaritea e te kamupene te whakapuakitanga hei whakararuraru i te whakarewatanga o te Falcon 9 a SpaceX, i te tūmanako i tēnei rā ki te whakamatau e taea ana te whakamahi anō i ngā pūkaha. Kua whakaatuhia e United Launch Alliance he mahere nui mo te rocket reusable i huaina ko 'Vulcan' e whakaritea ana kia rere i te tau 2019. Ka whakamahi a Vulcan i nga miihini hou, te whakaora i waenga o te rangi me te taumata o runga hou e whai ana ki te ahei i nga mahi matatini i runga i te aorangi. Ko te whāinga o te SpaceX me te ULA ko te whakamutu i te whakawhirinaki o Amerika ki ngā pūkaha rocket i hangaia e Rūhia, engari he uaua tonu te hangarau. Ko ngā pūkaha RD-180 i hangaia e Rūhia i tēnei wā kei te whakamana i te waka rererangi Atlas o ULA, engari kua rāhuitia e te Kaunihera ētahi atu kawemai hei wāhanga o ngā herenga tauhokohoko i whakaritea i muri i te whakaekenga a Rūhia ki Ukraine i te tau kua hipa. I kii a ULA ko te waahanga tuatahi o te rocket hou ka akiakihia e te tokorua o nga miihini oxygen-wai me te miihini methane wai e hangaia ana e Blue Origin. I kii te Tumu Whakarae a Tory Bruno i tetahi huihuinga purongo i Colorado ka hangaia nga miihini kia hoki mai ki te Ao, kia taea ai te whakahou me te rere ano. Ko te mahere a ULA ko te peke i te whakahoki i te kaitautoko katoa, he huarahi e manakohia ana e te SpaceX whakataetae. E tūmanako ana ia kia wehewehea ngā pūkaha i muri i te whakarewatanga, kia whakarewahia he arai wera ki a rātou, ā, kia tonoa he hīkoi ki te hopu i a rātou i te rangi. Ko te mahere a ULA ko te peke i te whakahoki i te kaitautoko katoa, he huarahi e manakohia ana e te SpaceX whakataetae. E tūmanako ana ia kia wehewehea ngā pūkaha i muri i te whakarewatanga, kia whakarewahia he whakangungu wera huri noa i a rātau, ā, kia tonoa he hīkoi ki te hopu i a rātau i waenganui i te rangi. Ma te whakamahi ano i nga miihini ka taea e te ULA te whakaiti i nga utu whakarewatanga ki te $ 100 miriona mo te kaitautoko-nui me te $ 200 miriona mo nga momo taumaha. Ko te haurua tēnei o te utu o te kohinga Delta 4 Heavy o ULA. I te timatanga, ka whakamahia e ULA tana miihini Centaur taumata-nui o mua engari kei te whakamahere ki te whakauru i te 2023 he miihini matatau ka taea te whakahou i nga miihini ururua. Ngā haora...
Kei te whakamahere a Vulcan ki te whakamahi i ngā pūkaha hou, te whakaora i waenganui o te rangi me te taumata o runga hou. Ka wehe ngā pūkaha i muri i te whakarewatanga, ā, ka hopukina e te hīkoi i waenganui i te rangi. Ka taea e ngā hōputu rokiroki anō te whakamutu i te whakawhirinaki o Amerika ki ngā pūkaha rokiroki o Rūhia. I whakamātau hoki a SpaceX i tēnei rā ki te whakamatau e taea ana e ngā pūkaha te whakamahi anō.
