Colonization of Mars.

Can we colonize mars? Yes, but do we have the technology to do so?

When this question comes we stop and think for a while, we already have sent orbiters, landers and rovers to the red planet, but we still lack the technology to send humans to mars and Before sending humans to colonize mars we first need to send them to live there for a while and then bring them BACK TO EARTH. I have highlighted back to earth because that is what we lacks in.

You have probably heard about "MARS ONE" if not then mars one is a project to send humans to mars but its only a one sided mission, we will send humans to mars but they will never return back. Why? because we don't have the technology to bring them back.

NASA is planning to send humans to mars by 2030s. It is sure that nasa will also plan a return mission. So by 2030s we will have the technology to bring humans back to their home planet.

But this is not the only thing we currently lack in there are many technical goals to achieve.

Then  why not make a list of technical goals we need to achieve before sending humans to colonize mars. That's what i did.

1) Super-Fast rockets and protection from radiation.

The distance between mars and earth vary from time as both earth and mars revolves around sun, Using a Hohmann transfer orbit the shortest distance between the both planets comes out to be 54.6 million kilometers this will require a rocket to spend approximately nine months in space to reach the distance.

Modified transfer trajectories that cut the travel time down to seven or six months in space are possible with incrementally higher amounts of energy and fuel compared to a Hohmann transfer orbit, and are in standard use for robotic Mars missions. Shortening the travel time below about six months requires higher delta-v and an exponentially increasing amount of fuel, and is not feasible with chemical rockets , but might be feasible with advanced spacecraft propulsion technologies, some of which have already been tested, such as VASIMR, and nuclear rockets . In the former case, a trip time of forty days could be attainable, and in the latter, a trip time down to about two weeks.

this advanced rockets will require a long time to get build and many test flights before we experiment them with humans. [We can't take risk]

And building super-fast rockets is only one goal, we also need to protect the astronauts from radiation during the journey. Cosmic radiation and solar wind cause DNA damage. which increases the risk of cancer significantly. The effect of long term travel in interplanetary space is unknown, but scientists estimate an added risk of between 1% and 19%, most likely 3.4%, for men to die of cancer because of the radiation during the journey to Mars and back to Earth. For women the probability is higher due to their larger glandular tissues.

Today we lack this technological requirement, or we have some of this but in an experimental state (high of risk).

This is my first post regarding "colonization of mars" and in this post i have explained only 1 point cause information overload is not good for health, follow up posts are on their way.
