Off Towards Mars Landing
From Phobos, it's a drop of six thousand kilometers to Mars. Luckily, escape velocity from the little moon is so low a galloping horse could manage it. With the heat shield blocking the main engine, the Universal Lander has only its thrusters to do the job. Fortunately, those little rocket motors feed from the same tanks as the main engine, and the propellant they need for the transfer to Mars still leaves enough for the final moments of the landing and for the return to orbit.
