Abort modes and the challenges of entry, descent and landing

For those tasked with designing robust and safe mission architectures, a manned mission to Mars presents problems far exceeding the challenges that have been faced before. For example, one of the overriding factors making a Mars mission so fundamentally different from lunar missions is the lack of opportunity to abort the mission, since, once the trans-Mars injection maneuver (TMI) has been performed, the crew is committed to a four to six month journey. Another equally formidable challenge is assuring the safety of the crew during the nerve-wracking entry, descent and landing (EDL), a phase most planners agree is the most dangerous part of the entire mission.
