星座任務列表

星座計劃是美國 NASA在2005年至2009年之間計劃的未來人類航天計劃，旨在開發一架新的載人飛船(獵戶座太空船)和一對發射器(戰神1號和戰神五號)，以繼續為國際太空站提供服務並重返月球。

截至2009年，已經進行了一次未載人的亞軌道發射試驗(戰神I-X)，預計載人飛行任務將從2014年到2017-2019年開始。2010年2月1日，美國總統歐巴馬宣布他打算取消該計畫在美國2011財年的預算。4月份的一項修訂提案確認，獵戶座飛船將保留用於近地軌道之外的未來任務，而戰神運載火箭則被重新開發成太空發射系統。然而，星座計劃被取消，近地軌道的運行被轉移到商業載人發展計畫，該計劃直到2020年載人天龍號太空船示範2號才開始進行載人發射。
