星座任务列表

星座计划是美国NASA在2005年至2009年之间计划的未来人类航天计划，旨在开发一架新的载人飞船(猎户座太空船)和一对发射器(战神1号和战神五号)，以继续为国际太空站提供服务并重返月球。

截至2009年，已经进行了一次未载人的亚轨道发射试验(战神I-X)，预计载人飞行任务将从2014年到2017-2019年开始。2010年2月1日，美国总统欧巴马宣布他打算取消该计画在美国2011财年的预算。4月份的一项修订提案确认，猎户座飞船将保留用于近地轨道之外的未来任务，而战神运载火箭则被重新开发成太空发射系统。然而，星座计划被取消，近地轨道的运行被转移到商业载人发展计画，该计划直到2020年载人天龙号太空船示范2号才开始进行载人发射。
