“It is time to venture beyond the known planets, on toward the stars.”
Yes, I agree, but I don’t see how any of the ideas in this article will help us achieve that goal. I think the problem is the reliance on conventional means of propulsion. Clearly some sort of bending of space/time is needed to leave the solar system faster than, say, a decade, let alone reach other star systems.
Dawn already used an ion engine (way too slow). The solar gravitational lens is neat but it won’t take us there physically. The “space-based laser” idea is funky but impractical.
Getting off Earth should help (Moon Base, Mars, somewhere else like Triton). Escaping our own planet’s gravity well takes way too much effort. But after that, it’s time to forget about rockets and start thinking of truly “wacked out” ideas.
For starters, Discover, how about dumping your absolutely awful page design? Yeesh, this page is hard to read.

We’ve learned a lot about Neptune’s largest moon, Triton, since it was first discovered in 1846. Some scientists
