Obstajajo razli\u010dni na\u010dini za izstrelitev in let ponovno uporabnih vesoljskih plovil.<\/p>\n

Vesoljski raketoplan za vzlet uporablja svoje lastne motorje skupaj z dvema zmogljivima trdnopogonskima raketnima oja\u010devalnikoma. To se v\u010dasih imenuje \u2018enostopenjski polet v orbito\u2019.<\/p>\n<\/div>\n

Ena od te\u017eav pri vesoljskih plovilih tipa \u00bbSpace Shuttle\u00ab je dodatna te\u017ea, ki jo predstavljata gorivo in raketni motorji. Kljub temu se mora \u00bbShuttle\u00ab na Zemljo vrniti kot jadralno letalo. Nima reaktivnih motorjev in ne more odleteti nazaj, da bi poskusil \u0161e enkrat, \u010de zgre\u0161i pristajalno stezo.<\/p>\n

Eden od na\u010dinov za zmanj\u0161anje velikosti vesoljskega plovila je, da ga del poti prepelje drugo plovilo. Na primer, veliko letalo lahko vesoljsko letalo prepelje do vi\u0161ine 10 km. Ko se vesoljsko letalo znajde nad ve\u010dino atmosfere, se ga sprosti.<\/p>\n

Raketo je mogo\u010de uporabiti tudi za izstrelitev vesoljskega plovila za ve\u010dkratno uporabo. V za\u010detku devetdesetih let prej\u0161njega stoletja je ESA preu\u010devala mo\u017enost izstrelitve majhnega vesoljskega letala z imenom Hermes na vrhu nosilne rakete Ariane-5.<\/p>\n

Druga mo\u017enost za zmanj\u0161anje te\u017ee bi lahko bila uporaba motorjev nove generacije, ki v prvem delu vzpenjanja izkori\u0161\u010dajo zrak iz na\u0161e atmosfere. \u0160ele ko bi plovilo doseglo vesolje, bi pre\u0161lo na raketni pogon, pri katerem bi porabljalo kisik iz zalog na krovu. Vendar pa bomo na tak\u0161ne motorje morali po\u010dakati \u0161e mnogo let.<\/p>","protected":false},"excerpt":{"rendered":"
