COLORADO SPRINGS, Colo. — Reinvigorating space exploration in the United States will require not only boosting NASA's budget but also getting the public to understand how pushing the boundaries of the space frontier benefits the country's innovation, culture and economy, said renowned astronomer Neil deGrasse Tyson.
Tyson, the director of the Hayden Planetarium in New York and an outspoken space advocate, delivered the opening address this morning (April 17) here at the 28th National Space Symposium.
"Space is a $300 billion industry worldwide," Tyson said. "NASA is a tiny percent of that. [But] that little bit is what inspires dreams."

He spoke about how space has influenced culture — ranging from how the fins on early rockets inspired fins on automobiles in the 1950s, to how the Apollo 8 mission's iconic picture taken in 1968 of Earth rising above the horizon of the moon led to a greater appreciation for our planet and the need to protect it. Yet, many people outside the space community see itas a special interest group, Tyson said.
"Innovation drives economy," he said. "It's especially been true since the Industrial Revolution."
Tyson advocated doubling NASA's budget — which President Barack Obama set at $17.7 billion in his 2013 federal budget request — and then laid out a different approach to space exploration that he called somewhat "unorthodox." Rather than focusing on one destination at a time, Tyson promoted building a core fleet of launch vehicles that can be customized for a variety of missions and for a range of purposes.

"We're kind of doing that now, but let's do that as the focus," Tyson said. "One configuration will get you to the moon. Another will get you to a Lagrangian point. Another will get you to Mars."
Having an available suite of launch vehicles will open up access to space for a wider range of purposes, which will, in turn, benefit the country's economy and innovation.
Tyson compared it with the country's system of interstates, which helped connect cities across the country and made travel more efficient.
"When Eisenhower came back from Europe after he saw the [German] autobahn, and how it survived heavy climactic variation and troop maneuvers, he said, 'I want some of that in my country,'" Tyson explained. "So he gets everyone to agree to build the interstate system. Did he say, 'you know, I just want to build it from New York to L.A., because that's where you should go?' No. The interstate system connects everybody in whatever way you want. That's how you grow a system."
Furthermore, this type of capability can be used for a myriad of purposes, including military endeavors, science missions, commercial expeditions and space tourism.
"Whatever the needs or urges — be they geopolitical, military, economic — space becomes that frontier," Tyson said. "Not only do you innovate, these innovations make headlines. Those headlines work their way down the educational pipeline. Everybody in school knows about it. You don't have to set up a program to convince people that being an engineer is cool. They'll know it just by the cultural presence of those activities. You do that, and it'll jump-start our dreams."
