When Will Interstellar Travel Be Possible?

With current technology, it would take close to 100,000 years to travel to another star system. But there's no need to restrict ourselves to doing things the way we're doing them right now.

Will we ever achieve interstellar travel?

The truth is that interstellar travel and exploration is technically possible. There's no law of physics that outright forbids it. But that doesn't necessarily make it easy, and it certainly doesn't mean we'll achieve it in our lifetimes, let alone this century. Interstellar space travel is a real pain in the neck.

Is NASA working on interstellar travel?

The basic idea for the interstellar mission is to launch a spacecraft weighing less than 1,700 pounds on NASA's massive Space Launch System rocket, which is expected to be ready by 2021. That will get it traveling across our solar system like any other probe.
