This could happen as soon as 2022

NASA wants to analyze some terrain samples from Mars in an effort to answer whether life exists there, but the problem has been transporting such samples from the Red Planet back to Earth. 

But now, it looks as though NASA has found a potential solution: customize a SpaceX Dragon capsule

While this is just a proposal for now and is by no means a planned mission with set funding yet, NASA said that modifying a SpaceX Dragon capsule into a landing craft could be a cost-effective way of bringing Martian samples back to Earth as soon as 2022. 

An internal study at NASA's Ames Research Center in Moffett Field, California revealed that the modified Dragon capsule -- dubbed "Red Dragon" -- would make a direct entry into the atmosphere of Mars and descend to the surface using retro propulsion for a precision touchdown (thanks to SuperDraco rocket engines) instead of a parachute system. 

The study suggests a Red Dragon could land roughly 2 metric tons of useful payload on Mars. A Red Dragon has "several times" the volume of the Viking heritage entry vehicle from the 1970s, and would be equipped to carry a Mars Ascent Vehicle (MAV), an Earth Return Vehicle (ERV), and hardware to transfer samples collected.


From there, the Red Dragon return vehicle would exit the Martian surface, thanks to some help from the MAV, and make its way toward Earth. 

A big plus for Red Dragon is that the mission would not require the transfer of samples from one vehicle to another in Mars orbit.

"The significance of the work is that it opens the door to the efficient achievement of an important planetary science objective at a lower complexity level and, by extension, at potentially lower cost than previously considered," said Andrew Gonzales, leader of the NASA study.

This certainly isn't NASA and SpaceX's first project together. SpaceX -- which is headed by Tesla CEO Elon Musk -- flew its Dragon capsule and Falcon 9 rocket to the ISS for the first time back in May 2012 for a test supply run. After that successful trip, SpaceX and NASA signed a $1.6 billion contract that allows SpaceX to complete 12 supply trips to the ISS and back.

In October 2012, the Dragon capsule completed its first official cargo run to the ISS, bringing home 1,673 pounds of cargo.

We are advancing at a fast rate, but there is an incredible challenge to settle on another planet. Personally I think the constraint of available usable energy sources is working against us. We are burning non-renewable fuels at alarming rate, and it is conceivable that we won't have enough to eventually leave and live on another planet just because there is no more efficient energy sources left to perform this undertaking. Space is so dangerous, mainly because the technology that we can put up there must work with a very limited energy constraint. Imagine a spacecraft having the energy resources of a whole city, we could probably use it to mine and manufacture other equipments in space. But we have no such spacecraft now.

Also, man has been flying since first man flight with hot air balloon, which was almost 250 years ago. Our spacecraft technology now is like the hot air balloon technology in terms of aviation history.

There is also no reason to believe the economy can be fixed in 10 years. It has been many ten years before it and the economy was never fixed, how could it happen now?

We have plenty of energy left on Earth! We have over 10,000 years of Uranium (estimated) and other fissile materials for nuclear power alone. We also have more hydrogen than we need.

Remember the law of conservation of energy: Energy can not be created nor destroyed.

We might be burning fossil fuels but that doesn't preclude us in no way of transforming sources into other sources of usable energy. Until we start physically taking material off this world, we have what we need. The only thing we are jeopardy of is running out of the initial catalyst in usable form--which at this point, is no longer pure oil. Nuclear power almost ensures our ability to exist thousands of years into the future.

Space might be dangerous but the Atlantic Ocean was dangerous to Columbus, too. That didn't stop him, either. Think of what this world would be like now if he (and others) had refused to take their voyages across.

We have plenty of energy left on Earth!

Having read most of that Tullett Prebon report from start to finish, that statement would be more accurate if written thus:
We have plenty of very expensive energy left on Earth!

The only way we can continue our current energy consumption rates is to offload the Earth's total carrying capacity elsewhere, by establishing human colonies in planets abroad. We have to start putting our eggs in more than one basket - or we all die. There is no other choice.

We have only about 30-60 years of uranium supplies (excluding reprocessing of spent nuclear fuel) and maybe 50-100 years of thorium if this planet goes from oil/gas/coal to nuclear, and by then we better have a successful process for sustained nuclear fusion. Right now the NIF is running a total negative return of energy with its experiments, even though its most recent firing tests generated more energy than consumed.

That requires everyone to embrace nuclear energy, not reject it like how there are protests against resumption and expansion of nuclear power generation because OMG FUKUSHIMA! We'll have war and famine before the total conversion takes place.
