NASA is developing capabilities for crewed missions beyond Low Earth Orbit (LEO) for the first time in nearly 50 years. Given the greater distances from Earth that these missions will entail, it is prudent to develop in-space abort capabilities in order to save the crew in the event of critical life-threatening failures that may occur. NASA has developed a Cross Program PRA (XPRA) of the integrated vehicle, from pre-launch through landing and rescue of the crew. An ascent abort model has already been developed as part of this XPRA model to assess the risk associated with failures during prelaunch and ascent. The scope of the analysis discussed here is focused on aborts associated with the in-space portion of the mission up to and including the Trans-Lunar Injection (TLI) burn, which places the Orion spacecraft on a trajectory to the Moon.
