Landing on Mars will be one of the most dangerous and rewarding space missions. One of the main issues with landing humans on Mars is figuring out how to slow down so the vehicle landing doesn't smash into the ground. The problem is Mars' thin atmosphere. This issue doesn't affect the Mars rovers' landings because those machines are lightweight. If humans land on Mars, they'll need to bring quite a bit of luggage and, without a dense atmosphere to provide friction, it'll be very difficult to slow this heavier payload.
