To get to the moon all we required was a ride, space suits, protein bars, and the famous shoreline towel. It was actually an end of the week hike by examination, and in some measure at the time we could treat it like one. It remains the biggest most convoluted and most costly logical investigation embraced by humankind. This is to give you a feeling of degree, since that was 50 years back. That was an end of the week get-away.
We can colonize Mars, however where anybody will ever truly need to property there is an issue for some discussion. We are not going to make it into another Earth, but rather we can manufacture a state of individuals who will experience their whole lives under mechanical life bolster, hermetically fixed far from the earth. Thus, agoraphobics and feline haters, at that point.
Shy of that, getting a group off the surface of Mars and back to Earth really isn't all that horribly troublesome. A rocket generally the span of the MAV appeared in The Martian is about the correct size, and it very well may be sent from Earth and arrived in front of any kept an eye on mission. Fuel can either be sent from Earth, made on and sent from the moon, or made set up on Mars. None of this is a lot of a stretch on a basic level, however we don't have anything like tried and man-appraised equipment to do this at the present time.
So… send a restricted mission, isn't that so? Well no, that would be blockhead. The quantity of things expected to set up a changeless base or state on Mars is inestimably more prominent than the generally basic matter of dropping off a ship and making fuel for it out of daylight and earth. Gracious, and if any of those bunch things endure a noteworthy mishap, everyone kicks the bucket.
