To land and take off between Mars and Moon are very different:

• Moon has 1/2 less gravity than in Mars.
• Moon has no atmosphere.

What will need more energy to land and take off per kilogram: Mars or Moon?

As the reference, the apollo lunar module 11 with weight of 14,696 kg landed on Moon. with the ascent module: 4,547 kg and the descent module: 10,149 kg. The LM descent propulsion system was more powerfull with 44.4 kN than the ascent propulsion system with 15.6 kN (ratio 3 to 1).

I tought that to land a big mass such as the Apollo 11 with over than 14,000 kilograms on Mars is actually impossible. It is hard for me to trade off between the Mars advantage of atmosphere to break the spacecraft and the Moon advantage of its half gravity to Mars.
