Will we ever...

Will we ever reach:

1. Another planet?
2. Another star system?
3. Another galaxy?

With humans, of course.

The question should be how fast vehicles can we build. If we could get enough energy to propel vehicle to 0.99 speed of light it would make possible to travel to different stars even those thousand of lightyears away according to relativity theory, but it would be not very practical as on Earth time would pass normally.
