No need for interstellar travel just yet & I don't believe there will EVER be intergalactic travel. We could however start within the solar system right now with the technology we have.Until humans can travel faster than light, we are going nowhere. The closest star is over 4 light years away...
The moon & Mars are easily obtainable goals for colonization. Down the road, outer planet moons such as Titan, Ganymede & Europa could be promising candidates as well. Until then...
It is fun seeing NASA, ESA & CSA working together and doing what they do.It is fun to see NASA back in action again.
