Why Colonize Mars?
Fair question. It is a desolate, hostile planet a long way from earth with seemingly little to offer. Yet it holds an intrigue for both scientific and potentially commercial advances.
Space is one of the last frontier for us to explore and as the only planet in our solar system that can be potentially colonized Mars has long been studies but we really have known very little about it until recently.
Apart from all the scientific questions that can be answered probably the biggest reason is to push human endeavor beyond what we have currently achieved. To mount a mission to Mars we will have to vastly improve all sorts of technologies from mechanical and atmospheric challenges to everyday living and building on a planet that offers little resources. The technologies will find their way into our cars, our homes and lives and who knows one day they may be essential to sustain life on this planet.
