China Moon Landing Part of New Space Race by Emerging Nations

Article excerpt

LOS ANGELES - China watched this month as the nation's first lunar rover rolled across the moon's surface.

It was a moment of national pride when images of the six-wheel rover, dubbed Jade Rabbit, were transmitted live back to Earth, showing the red and gold Chinese flag on the moon for the first time.

"Now as Jade Rabbit has made its touchdown on the moon surface," the state-run Xinhua news agency said, "the whole world again marvels at China's remarkable space capabilities."

The lunar triumph offered many Americans their first glimpse at an unfolding new space race involving countries with emerging economies. Space exploration, once the exclusive domain of the world's superpowers, is now being undertaken by dozens of nations aiming to show the world their technological prowess.

Although these countries are still decades behind the United States in space technology, their push into the cosmos comes at a time when NASA has been wrestling with budgetary restraints and struggling to achieve new milestones in space flight.

It prompted Buzz Aldrin, the former astronaut now from Los Angeles and the second man to walk on the moon, to say in an interview that U.S. government officials lack leadership in space exploration.

"They are ignoring the achievements of what we risked our lives for," he said. NASA's funding "is totally inadequate for an endeavor that brings so much inspiration to the American people and educating the next generation."

The U.S. must stay at the forefront of space exploration by helping all countries, including China, advance their programs, he said. An existing law prohibits NASA from working with China, but Rep. Frank R. Wolf, R-Va., the fiercest opponent of international cooperation with the country, announced his retirement this month.

"A number of nations have evolved their capabilities to put humans into space and beyond Earth," Aldrin said. "We should help contribute to their exploration."

According to the aerospace consulting company Futron Corp., China has had 15 launches this year with one more planned. Russia has had 32 launches, and three more are slated before the end of the year. The U.S. will finish with 19.

But space exploration has reached far beyond these three countries. About 70 nations have space programs.

Last week, the European Space Agency launched its $1.3 billion Gaia spacecraft, which is designed to map out more than 1 billion stars in the Milky Way. Iran has sent two monkeys into space - most recently last week - and has plans for a manned mission.

In November, India launched its first robotic probe to Mars. The country has already sent a probe to the moon and plans to send a second one by 2017.

None of these missions approaches the difficulty of the highly choreographed landing on Mars that NASA's Jet Propulsion Laboratory in La Canada-Flintridge executed last year with its 1-ton Curiosity rover. But there are questions in the aerospace industry about what NASA's next major milestones will be and how they will be funded.

The nationwide fascination and allure of the Apollo era is long gone. NASA accounted for more than 4 percent of the federal budget during the 1960s; now it is less than one-half of 1 percent.

NASA's proposed budget is expected to be about $18 billion next year, and some in Congress want to slash it further.

To many Americans, routine flights of the space-shuttle era have made the feat rather mundane. …
