<prompt> Yini okungenzeka isetshenziselwe ukutadisha iplanethi yesibili ekude kakhulu elangeni? Njengoba kunikezwe umbuzo odlule, bhala umongo onempendulo yawo. Kungaba imisho engu-1 kuya kwengu-20. Umongo:  <response>: Ngaphandle kokufika kwabantu enyangeni, i - NASA yahlola izinhlelo zokusebenza eziningana ze - Apollo ngemva kokuya enyangeni. I-Apollo Extension Series i-Apollo X, yaphakamisa izindiza ezingafika kwezingu-30 eziya emzileni womhlaba, kusetshenziswa isikhala esise-Spacecraft Lunar Module Adapter SLA ukufaka ilabhorethri encane emzileni indawo yokusebenzela. Izazi zezinkanyezi zaziyoqhubeka zisebenzisa i-CSM njengesikebhe esiya esiteshini. Lolu cwaningo lwalulandelwa ukuklanywa kwe-workshop enkulu yokujikeleza ezokwakhiwa emkhathini kusuka esigabeni esingenalutho se-S-IVB Saturn, futhi yakhula yaba yi-Apollo Applications Program AAP. Lo mhlangano kwakufanele uhlanganiswe ne - Apollo Telescope Missions, eyayizothatha indawo yemishini yesiteji sokwehla kwe - LM kanye nenjini nge - solar telescope observatory. Uhlelo olwalunezifiso eziphakeme kakhulu lwalufuna ukusebenzisa i-S-IVB engenalutho njengesikebhe sasemkhathini esiphakathi kwamaplanethi ohambweni lokudlula eduze kweVenus.
