He aha pea te mea i whakamahia hei ako i te aorangi tuarua i tawhiti atu i te ra? I runga i te pātai o mua, tuhia he horopaki kei roto te whakautu. Ka taea te 1 - 20 rerenga kōrero. Te horopaki:
I tua atu i nga taunga a te tangata ki te marama, i tirotirohia e NASA etahi tono i muri i te marama mo nga taputapu Apollo. Ko te Apollo Extension Series (Apollo X,) i whakaarohia kia 30 nga rerenga ki te aorangi o te Ao, ma te whakamahi i te waahi i roto i te Spacecraft Lunar Module Adapter (SLA) ki te noho i tetahi whare taiwhanga iti (whare). Ka whakamahia tonutia e ngā kaipuke ā-ao te CSM hei waka ki te teihana. I whai ake i tenei rangahau te hoahoa o tetahi awheawhe awheawhe nui ake hei hanga i roto i te awheawhe mai i te taumata o runga o Saturn S-IVB kau, ka tipu ki te Apollo Applications Program (AAP). Ko te awheawhe i whakaotihia e Apollo Telescope Missions, e whakakapi ana i nga taputapu o te waahanga heke o te LM me te miihini me te tirohanga a te telescope solar. Ko te mahere tino nui ko te whakamahi i tētahi S-IVB kau hei waka ā-ao mō tētahi misioni rere-i runga i a Venus.
