Shuttle-science payoffs abound

WASHINGTON

Science from the space shuttle helped open Earth’s eyes to the cosmos and sister planets. It created perhaps the most detailed topographical map of Earth. And it even is helping doctors understand, and sometimes fix, what’s happening in our aging and ailing bodies.

If you need help getting out of a crashed car, or if you’re a soldier maneuvering around an active land mine field, space shuttle- derived technology may have saved your life.

And thanks to the space shuttle, we have healthier baby formula and cooling socks to wear in hot weather.

Most Americans wrongly credit the Apollo moon program with creating Earthly “spinoffs” of new technology that it never did: sticky Velcro, nonsticky Teflon and orange-powdered Tang — all things used by NASA but not invented there.

Yet the 40-year space shuttle program often doesn’t get recognized for its science and technology, NASA says. And shuttle-based science will come to an end when Atlantis — carrying mouse stem-cell and vaccine experiments — comes home today.

Of course spending nearly $200 billion on any advanced technology will pay off in various unplanned ways. And one scientist, a prominent critic of manned spaceflight, says NASA’s claimed benefits are more hype than hope.

Scientists who have worked with and for the space agency say shuttle research has paid off.

“There’s been a good deal of science learned on the shuttle,” said MIT astronautics and health technology professor Laurence Young, who has sent experiments on seven shuttle flights, mostly on how weightlessness affects the body.

Science wasn’t the reason the shuttle was built, said Rice University physicist Neal Lane, who was the head of the National Science Foundation and President Bill Clinton’s science adviser. However, the shuttle and the International Space Station — which couldn’t be constructed without the shuttle — are unprecedented places for important science.

People overlook the increased understanding in human biology that the shuttle and station have provided, Lane said. “We’ve learned some things about the human body that we had no other way to learn except to operate for some period of time in space.”

Astronauts lose bone strength, have balance problems and weakened immune systems that in many ways are similar to aging. Studying how to combat bone loss on shuttle astronauts with exercise and other activity may help the Earth-bound, they figure.

Still, the most obvious science the shuttle helped generate is with astronomy. Exhibit 1 is the Hubble Space Telescope, which changed Earth’s view of the cosmos and even its understanding of the age of the universe.

It was launched with the shuttle, fixed with the shuttle and upgraded four other times by spacewalking shuttle astronauts. Without all that, Earth’s view of the rest of the universe would have been fuzzy at best.

Former NASA science chief Alan Stern said the shuttle launched three other major space exploration probes: Galileo, which gave close-up views of Jupiter and its moons; Magellan, which mapped hot chaotic Venus; and Ulysses, which examined the sun’s larger influence on the edges of the solar system.

But what’s taken for granted even more is how the shuttle improved our view of our home planet with one flight in 2000. The spacecraft carried a set of special radar instruments that mapped most of the world, including previously inaccessible areas such as jungles and mountaintops, with the most precise topographical measurements ever. This is important for military planning and aviation.

“It’s a gift that is going to keep on giving. It’s going to affect science, environment and national security,” said University of Tennessee aviation and flight research professor John Muratore, a former NASA flight director. “And that is a really undervalued mission.”

Another overlooked item from the space shuttle is the bioreactor, Muratore said. It originally was designed to grow cells and tissue in space for experiments in zero gravity, but it’s used on Earth for all sorts of biomedical research, he said.
