Naa. A planet ~20 light years away would take 20 years to get there with a velocity equal to the speed of light. now... traveling at the speed of light is not possible, so it'll take longer than 20 years to get there. I do not believe we'll attempt a mission to a place that'll take that long to get to.
an unmanned endeavor might be different. we'll send something, wait ~30 years, then remember how inferior we were 30 years ago with depleted technology. ha... but wait.. communication will take another 20 years to transmit/receive if it is traveling at the speed of light.

so actually, i dont think we'll go through with a mission like this anytime soon, unless we have a dramatic advance in technology.
