The top two contenders for the Republican presidential nomination pushed for further privatization of spaceflight during Monday's debate in Florida.
Both Mitt Romney and Newt Gingrich stressed the importance of space exploration for the United States, saying a strong space program helps develop key technologies and inspires young people to study science and engineering.
But during the debate, held at the University of South Florida in Tampa, neither candidate said giving NASA more money was the right way forward.

Teen's space mission fueled by social media
Science editor Alan Boyle's blog: "Astronaut Abby" is at the controls of a social-media machine that is launching the 15-year-old from Minnesota to Kazakhstan this month for the liftoff of the International Space Station's next crew.

Romney criticized President Obama for failing to give NASA a mission or a vision. Romney advocated creating a coalition — including the president and leaders from the military, academia and the business community — that would set NASA's course. [Vote Now! The Best Spaceships of All Time]
"Bring them together, discuss a wide range of options for NASA, and then have NASA not just funded by the federal government but also by commercial enterprises," the former Massachusetts governor said, responding to a question from a moderator about whether space exploration should be a priority.
"Let's have a collaborative effort, with business, with government, with the military as well as with our educational institutions," Romney added. "Have a mission, once again excite our young people about the potential of space, and the commercial potential will pay for itself down the road."
Gingrich was then asked whether he, as president, would put more federal money toward the goal of sending astronauts to Mars as soon as possible. The former House speaker said he favored spending federal money in a different fashion — instituting, for example, a series of prizes to encourage space exploration.
"Most of the great breakthroughs in aviation in the '20s and '30s were the result of prizes. Lindbergh flew to Paris for a $25,000 prize," Gingrich said. "I would like to see vastly more of the money spent encouraging the private sector into very aggressive experimentation."
Some of those prizes, he added, might reward getting humans back to the moon, sending them to Mars, building space stations and developing the commercial spaceflight industry.
"There are a whole series of things you can do that could be dynamic that are more than just better government bureaucracy," Gingrich said. "They're fundamentally leapfrogging into a world where you're incentivizing people who are visionaries, and people in the private sector to invest very large amounts of money in finding very romantic and exciting futures."
Gingrich also implied he would trim NASA's budget, which currently represents roughly 0.5 percent of the federal budget.
"I'd like to see a leaner NASA," he said. "I don't think building a bigger bureaucracy and having a greater number of people sit in rooms and talk gets you there."
Texas congressman Ron Paul and former Pennsylvania senator Rick Santorum also participated in the debate, but neither one was given time to address the two space-related questions.
