The Old space craft design they used for the moon landing is not suitable for a Mars landing because the design would not accommodate enough fuel to escape Mars atmosphere . The space craft would have to be built larger . The old moon landing technology can be used to land on the moons Phobos or Deimos that orbit Mars .
If a space craft was going to land on Mars with astronauts, the best place to land would be on top of Olympus Mons . This is because the volcano is 16 miles high giving an Earth return space vehicle a head start in escaping Mars gravity to fly back into space . If Olympus Mons is unsuitable there is other very high volcanos which are extinct that present themselves as good landing points for Earth return ( this plan is best tested without astronauts ).
It would be best to use a space station as a space vehicle to fly astronauts to Mars . The space station would have to be built like a giant wheel and rotated to provide artificial gravity . This space craft ( built like a giant space station ) would provide the necessary comfort for astronauts for a successful journey to Mars . The only problem to define, is how fast would it be traveling and how long would it take for something the size of a space station to reach Mars .The accommodation at the center of the space station wheel would best be used as a green house to produce food, recycle waste and reprocess breathable air back in the system . .The rest of the station used for normal accommodation and operations .
escape pods could be used to fly down to Mars to land on Mars Olympus Mons and then return to the space station .

Centrifugal force: Unlike real gravity which pulls towards a center, this pseudo-force that appears in rotating reference frames gives a rotational 'gravity' that pushes away from the axis of rotation. Artificial gravity levels vary proportionately with the distance from the centre of rotation. With a small radius of rotation, the amount of gravity felt at one's head would be significantly different from the amount felt at one's feet. This could make movement and changing body position awkward. Again, slower rotations or larger rotational radii should not lead to such a problem.
The Coriolis effect gives an apparent force that acts on objects that move. This force tends to curve the motion in the opposite sense to the habitat's spin. Effects produced by the coriolis effect act on the inner ear and can cause dizziness, nausea and disorientation. Experiments have shown that slower rates of rotation reduce the Coriolis forces and its effects. It is generally believed that at 2 rpm or less no adverse effects from the Coriolis forces will occur, at higher rates some people can become accustomed to it and some do not, but at rates above 7 rpm few if any can become accustomed. It is not yet known if very long exposures to high levels of Coriolis forces can increase the likelihood of becoming accustomed. The nausea-inducing effects of Coriolis forces can also be mitigated by restraining movement of the head. Head restraints are perhaps practical for exercising in artificial gravity (an artificial gravity gym), but not for much else.
This form of artificial gravity gives additional system issues:
The size and speeds and period of different radii of space stationThe engineering challenges of creating a rotating spacecraft are comparatively modest to
Kinetic energy: Spinning up parts or all of the habitat requires energy. This would require a propulsion system and propellant of some kind to spin up (or spin down) or a motor and counterweight of some kind (possibly in the form of another living area) to spin in the opposite direction.
If parts of the structure are intentionally not spinning, friction and similar torques will cause the rates of spin to converge (as well as causing the otherwise-stationary parts to spin), requiring motors and power to be used to compensate for the losses due to friction.
Angular inertia can complicate spacecraft propulsion and altitude control particularly when no counterweight is employed.
The engineering challenges of creating a rotating spacecraft are comparatively modest to any other proposed approach. Theoretical spacecraft designs using artificial gravity have a great number of variants with intrinsic problems and advantages. To reduce Coriolis forces to livable levels, a rate of spin of 2 rpm or less would be needed. To produce 1g, the radius of rotation would have to be 224 m (735 ft) or greater, which would make for a very large spaceship. To reduce mass, the support along the diameter could consist of nothing but a cable connecting two sections of the spaceship, possibly a habitat module and a counterweight consisting of every other part of the spacecraft. It is not yet known if exposure to high gravity for short periods of time is as beneficial to health as continuous exposure to normal gravity. It is also not known how effective low levels of gravity would be to countering the adverse effects on health of weightlessness. Artificial gravity at 0.1g would require a radius of only 22 m (74 ft). Likewise, at a radius of 10 m, about 10 rpm would be required to produce Earth gravity (at the hips; gravity would be 11% higher at the feet), or 14 rpm to produce 2g. If brief exposure to high gravity can negate the health effects of weightlessness, then a small centrifuge could be used as an exercise area.
The Gemini 11 mission attempted to produce artificial gravity by rotating the capsule around the Agena Target Vehicle which it was attached to by a 36-meter tether. The resultant force was too small to be felt by either astronaut, but objects were observed moving towards the "floor" of the capsule.

I was thinking that I could react water already on Mars into Oxygen and Hydrogen producing the required fuel for lift off for a space pod to return to the space station.
