Beyond Helium 3

Hypothetically speaking, are there any known elements found only in outer space that might one day economically justify a renewed commitment to space exploration? (Helium 3 not included.)

(For a sci fi story I'm working on.) Helium 3 is very well known, but other than that, are there any materials known to exist (or even SUSPECTED to exist) off-planet that might be valuable enough to merit a vastly larger budget for NASA?
Of course if we poisoned the water or the Earth enough that we needed to move, extra-terrestrial real estate would be in high demand. But I'm not interested in apocalypse scenarios, I'm more interested in the idea of resources farmed in space, that people on Earth could use while still remaining on-planet.
It's okay if it is something that only exists (or hypothetically exists) in deep space, far beyond the reaches of today's technology.
