We're not going beyond our solar system. Ever. The nearest star is 4 light-years away. Assuming you could even travel at the speed of light, which you can't, it takes 1 year to reach the speed of light while accelerating at a comfortable 1G. But, as I said, we're not ever traveling at the speed of light. 20% of the speed of light is about the best we'll realistically ever be able to do - but that still makes the nearest star over 20 years of travel away!
How do you propose to travel for over 20 years?
It's clear then that robots will be exploring the solar system, not us. Even then it's going to take several centuries just to travel to, collect data from, and send back to earth just from the local stars we can see with the unaided eye.

When they say space is big, space is BIG.
