“Flying saucers aside, a visceral childhood fascination with what’s out there, launched by pop culture and propelled by real-life space missions during NASA’s heyday, is a recurring narrative among SETI researchers. “I’m a child of the Apollo era,” said Mark Showalter, a Sagan Center senior research scientist. “I’m in this room today because of Neil Armstrong. Watching the moonwalk — that was the most exciting thing I’d ever seen in my life.” To date, Showalter has discovered, or co-discovered, six moons in the solar system: Pan (orbiting Saturn); Mab and Cupid (Uranus); Kerberos and Styx (Pluto); and just last year, a Neptune moon, still unnamed. “We could be sending missions to all kinds of fantastic destinations and learning things for decades to come,” he said. But the scheduled NASA voyages to the outer planets appear nearly done.  The New Horizons spacecraft flies by Pluto next year; the probes to Jupiter and Saturn shut down in 2017. Even the much-heralded Clipper mission — the proposed robotic expedition to Europa — isn’t yet a go. So far, with a projected $2 billion cost, only $170 million has been appropriated. At 56, Showalter concedes that his professional career will conclude with these final journeys. “It takes twenty years from the time you start thinking about the project to the time you actually get to the outer planets,” he said. And without new missions, he worries, and wonders, about the new generation. “It’s the missions that capture imaginations. If those aren’t happening, kids might not go into science the way my generation did.”

“One thing we’ve learned in the last 500 years of astronomy: Every time we thought we were a miracle, we were wrong.”
