NASA aims to reduce asteroid threat

Add this to your worry list: orbiting somewhere near Earth are an estimated 13,000 asteroids big enough to possibly level a country and NASA has no clue as to when, where or whether they might strike.

Worse, astronomers think their sky maps might still be missing an additional 50 to 100 asteroids so massive roughly a kilometre across or larger that they could end civilisation if they hit Earth.

With those cosmic threats in mind, the Obama administration on Tuesday unveiled a "grand challenge" that would redouble efforts by NASA and challenge amateur astronomers to catalogue every asteroid near Earth that's large enough to cause significant damage. NASA also is being asked to lead a new campaign to figure out how to defend Earth from doomsday rocks.

"We want to prove that we are, in fact, smarter than the dinosaurs," said NASA deputy administrator Lori Garver, referring to the massive asteroid or comet that scientists think killed the dinosaurs about 65 million years ago.

Though her example was dramatic, Ms Garver didn't have to reach that far back to show what a space rock can do to Earth. Just this February, an asteroid 17 metres in diameter exploded over Russia, injuring more than 1000 people. And car-sized asteroids enter and burn up in the atmosphere almost weekly.

As it stands, NASA has located about 95 per cent of the asteroids big enough to annihilate everyone on Earth and none poses any immediate danger of hitting the planet. But they are a lot less certain about where to find the smaller ones.

NASA scientists estimate that about 13,000 asteroids larger than 140 metres which have the potential to level a country remain undiscovered. And there could be millions more that are close in size to the Russian asteroid.

"We have done a very good job on the big ones. It's the smaller ones that could be a potential threat and where we have a lot of work to do," said Jason Kessler, of NASA's chief technologist office.

Mars beyond reach without NASA budget boost

If NASA continues to be funded at its current levels, a manned mission to Mars could be permanently beyond reach, space industry experts say.

When asked how soon astronauts could potentially set foot on Marsunder NASA's current budget constraints, Thomas Young, the former executive vice president of Lockheed Martin, says the outlook is bleak.

"With the current budget, bear with me, I would probably say never," Young said during a meeting of the U.S. House of Representative's space subcommittee Wednesday. [Boldest Mars Missions of All Time]

Steven Squyres, the principal investigator for NASA's Opportunity rover now exploring Mars, agreed. Squyres, an astronomy professor at Cornell University in Ithaca, N.Y., also gave testimony before the House subcommittee.

Young said that if the public and government officials treat a mission to Mars with the importance of the first mission to the moon, it is possible to put boots on the Red Planet in a little more than a decade from now.

"Mars is harder; there are a lot of significant issues to resolve before going to Mars," Young said. "But I think that if we had the same national commitment to it (as we did to going to the moon), I would say by 2025, we could land on Mars."

The current draft of NASA's budget produced by the House asks the space agency to develop a roadmap that will define the technical capabilities needed to send humans to Mars sometime in the future.

On Tuesday, NASA announced anAsteroid Grand Challenge that solicits the publics help in proposing asteroid-wrangling strategies for the agencys Asteroid Initiative.

"NASA already is working to find asteroids that might be a threat to our planet, and while we have found 95 percent of the large asteroids near theEarth's orbit, we need to find all those that might be a threat to Earth," said NASA Deputy Administrator Lori Garver, in a press release. "This Grand Challenge is focused on detecting and characterizing asteroids and learning how to deal with potential threats. We will also harness public engagement, open innovation and citizen science to help solve this global problem."

NASAs Asteroid Initiative includes the capture and redirection of a 500-ton near-Earth asteroid into a stable orbit as well as missions to send astronauts to asteroids. According to the initiatives current timeline, NASA will assess asteroid candidates until 2016, launch a mission to the asteroid in 2017, capture the asteroid in 2019, and send it into trans-lunar orbit in 2021. Throughout that timeline, NASA will test the unmanned Orion spacecraft, in hopes of sending a manned mission aboard the craft in 2021.

That timeline is ahead of the presidents goal to send humans to an asteroid by 2025 and a manned mission to Mars by the 2030s. Efforts to develop the technology to deflect asteroids have become particularly meaningful since a meteor plunged to the earth near the Russian city of Chelyabinsk in February, killing no one but reminding us of our vulnerability here on Earth.

The space agencys outline for how it will capture an asteroid is still vague and thats why it wants the publics help.

The Asteroid Grand Challenge is an effort to develop collaborations with government agencies, international partners, industry, and academia, as well as citizen scientists. At the same time, NASA has also put out a Request for Information, which will be open for 30 days for the agencys potential partners to submit their asteroid-grabbing ideas.

Nanotechnology: Driving Sustainability

Check your rear view mirror. That car zooming toward you may be fueled by natural gas and its gaining fast.

Want proof? They were showing off a BMW X3 SUV, a Ford Mustang Coupe and even a family-friendly Ford Taurus powered by compressed natural gas, or CNG, in Southern California a few weeks ago. This road show of retrofitted vehicles, a project of an association of natural gas companies, is going national over the summer.

In the worthwhile journey to sustainability CNG-powered cars are the logical next leg.

About 70% of oil is burned for transportation, and it generates almost a third of greenhouse gases. CNG burns cleaner, significantly reducing emissions, including 90+% less carbon monoxide compared to gasoline.

Of course, were only in first gear when it comes to putting environmentally sustainable CNG-powered cars in every American driveway. Fleet and municipal vehicles are miles ahead, showing the rest of us the way. According to the Department of Energy, there are about 112,000 vehicles powered by natural gas in the U.S. mostly buses, garbage trucks and delivery vehicles.

Nanotechnology will play an important role in our transportation conversion. In the longer term, I predict nanomaterials will be used for lightweight impact-resistant fuel tanks. As we invent the infrastructure for filling stations, theres an opportunity to nano-engineer for more durable, efficient, reliable distribution systems, too.

For now, theres one crucial area where nanotechnology is already up to speed: efficient, safe sustainable extraction. Natural gas extraction, including hydraulic fracturing, is going on in 31 states. The venues range from oil sands in the Dakotas to family farms in Pennsylvania. Everyone involved is concerned about protecting the environment reflecting the same goals as vehicle developers.
