  • If the TMI stage propulsion system should fail between 3.3 and 3.7 km/s ΔV, the crew can get back to Earth orbit by retrofiring the hab’s propulsion system; between its midcourse correction, Mars orbit propulsion maneuver system, and landing propellant, the hab has a total ΔV capability of 0.7 km/s—more than enough to negate the maximum excess ΔV of 0.4 km/s that could strand the crew between Mars and Earth.
