The Space Travel conflict: Once we get there, how will we get back?

There is a problem I have come upon while researching this topic, which sways my opinion a little bit, that is once we get to Mars, how will we return? Here on Earth everything is done right. We have liftoff from a Launchpad, 100's of people monitor the ship closely for any problems, there is a study of the climate for clear weather, and the shuttle is filled have thousands of tons of fuel. We also know what speed it takes to get out of Earth's atmosphere. Depending on where we go, for example, Mars has less gravity than Earth which means there is less friction and will enter in the atmosphere faster there than it would here on Earth. How will we slow down once we enter the atmosphere? How will we land? How many teams of astronauts would we send? This is a big mission I would expect at least 5 teams of 7 on independent shuttles. I will explain why later. These questions are just more reasons why we haven't sent people to Mars. The 7 minutes of terror will be more like an hour of terror in our astronaut’s eyes. I am not one for sending people on suicide missions, and I don't think NASA is either. I believe this process would be a lot easier if space shuttles were more agile but still sturdy enough to travel in space. What I mean is, once entered in Mars's atmosphere, the space shuttle should have better flight control like an airplane so it can circle in the sky and maybe fly around, searching for the best spot before landing. Instead of putting all of our hopes into a spacecraft that just glides. Now don't get me wrong, space shuttles do have flight commands that the astronaut can use to help guide the shuttle along. What I'm trying to say is, in order to fly like a plane we have to have engines like a plane, as well as the engines it takes to get into outer space. Maybe we could just have them deploy from a compartment once we enter in the atmosphere of Mars, after space flight to protect them from micrometeorites and what not. This is how we could get there and land safely. That is just the beginning. Once we are there and safely landed how will we get back? This would have to be an expedition that lasted months and months. There is no launch pad, no place to refuel, and no extra supplies. That means not long after their launch we would have to be preparing to launch more supplies. Since this expedition is going to take a long time, as I said earlier we would need a rather large expedition for this. Around 5 teams of 7 astronauts would be the minimum sent to Mars constantly over time. Those teams would consist of doctors, scientists, meteorologist, and engineers of all sorts. I'm sure there are more people needed but all of the people would get together to build some kind of shelter, maybe one you would find in the arctic for people who explore there, a lab of sorts. Once settled in, NASA would have to keep sending the tools to build until there are suitable living conditions. How are we going to get back once we are on mars? After searching the internet I finally found a reliable source. We would not come back after reaching Mars; we are going to colonize Mars. In my eyes it will be the biggest and longest migration of tremendous proportions in the history of mankind. According to the source, Colonizing Mars will not go super-fast. We will send a group of astronauts to mars and then another group and another group until a suitable building where they could live is built and by 2033 we will have 20 astronauts living and sustaining on Mars. Not to scare you but by 2050 our population will reach 10 billion and by 2100 15 billion. We are going to run out of space. What's our only solution? Moving to space; it's the only other alternative.

"The Human race has no future unless we go into space"- to be more specific: “I don't think the human race will survive more than 1,000 years unless we spread into space."

This site has questions about colonizing Mars and scientists answering them, telling about the fast approaching mission to colonize Mars in the year 2033. It also has some ideas as to how and why we are going to do it.

This source seems to be credible but there is no evidence of any citations. One lady did give credit to Steven Hawking after she used one of his quotes. That is why I believe this site to be credible. There is not much information about colonizing Mars so that is why I can’t give full credibility to this site. I also would not use this site in a paper because of the lack of credibility and because it still is not much information on this topic.
