re: When, if ever will we have spacecraft that can travel at light speed?

That is how it works. If you're in a jet moving 500 mph, and you throw a football forward at 20 mph, the football is moving 520 relative to the ground.
What if you shot the football forward out of the spacecraft while traveling the speed of light through space. Could it go faster than the speed of light?

Nothing can go faster than light speed, but I have no idea what would happen to the football. Does Neil Degrasse Tyson post in this bitch?

Without getting too technical. Your hypothetical is impossible for two reasons. 1. You can't travel at light speed and 2. Nothing can go faster than light speed.
But even so when you throw a ball it's moving away from you. It's reference frame is traveling relative to you.
When you add things like time dilation into the mix it can help account for why to the observer on the ground it would not break light speed.
