The question is : will we be able to get to that planet and reproduce once we get there?
1] We have chemical rocketry which will get us very inneficiently of the planet and 90%+ is throwaway at launch!
FAIL! ... Moving on!...
2] We potentially have the Roswell disc's sitting in some far off wonderland! Will we ever get to see it, access it, use it???
FAIL! ... Moving on!...
3] We have nuclear propulsion designed to be feasable in the 1950's under Project Orion!
Project Orion (nuclear propulsion)
[wiki]
Project Orion was a study of a spacecraft intended to be directly propelled by a series of explosions of atomic bombs behind the craft (Nuclear pulse propulsion). Early versions of this vehicle were proposed to have taken off from the ground with significant associated nuclear fallout; later versions were presented for use only in space.
The low thrust requires ion thrusters to provide continuous thrust for a very long time in order to achieve the needed change in velocity (delta-v) for a particular mission. To achieve these delta-vs, ion thrusters are designed to last for periods of weeks to years.
In practice the lifetime of ion thrusters is limited by several processes.

I saw the other day there are currently 2 men and one women up on the International Space station at the moment. I wonder if they have been conducting tests. I mean those guys are up there for a hell of a long time and well maybe they do a few tests all in the name of science.
