List of Constellation missions

The Constellation Program was NASA's planned future human spaceflight program between 2005 and 2009, which aimed to develop a new crewed spacecraft (Orion) and a pair of launchers (Ares I and Ares V) to continue servicing the International Space Station and return to the Moon.

As of 2009, a single unmanned suborbital launch test (Ares I-X) had been flown, with crewed missions anticipated to begin between 2014 (by NASA projections) and 2017-19 (according to the independent Augustine Commission). On February 1, 2010, President Obama announced that he intended to cancel the program with the U.S. 2011 fiscal year budget. A revised proposal in April confirmed that the Orion spacecraft would be retained for future mission beyond low earth orbit, with the Ares launchers redeveloped into the Space Launch System. However, the Constellation Program itself was cancelled, with low-earth orbit operations transferred to the Commercial Crew Development program.

Development of mission plans

In October 2006 NASA released a draft schedule of all planned NASA Project Constellation missions through 2019. This document included descriptions of a series of proposed vehicle test missions. In July 2007 the schedule was reviewed. In January 2008 the schedule was again reviewed. The most recent published set of milestones is from February 2009. Also, an independent assessment by the Review of United States Human Space Flight Plans Committee in October 2009 found that under NASA's then-current plans and budget the Ares I would not be ready to launch until 2017-2019, with the Ares V not available until the late 2020s.

On October 11, 2010, the Constellation program was cancelled, ending development of the Altair, Ares I, and Ares V. The Orion Crew Exploration Vehicle was renamed the Orion Multi-Purpose Crew Vehicle (MPCV), to be launched on the Space Launch System.

Ascent abort tests

These will be conducted using the Orion Abort Test Booster (ATB), similar to the Little Joe II used for Apollo testing. A boilerplate Orion capsule and the escape tower will be tested on these missions.

Pad abort tests

These were planned to test the launch escape system of the Orion spacecraft on the launchpad.
