Tuesday morning, the House Science Committee summoned NASA chief Charles Bolden to discuss the possibility of a major asteroid colliding with Earth. There were, probably, many enlightening conversations, but we'll focus on just one, as highlighted by the New York Daily News:

"What would we do if you detected even a small one like the one that detonated in Russia headed for New York in three weeks? What would you do?" Rep. Bill Posey (R-Fla.) asked.

The witnesses turned to look at each other. "Bend over and what?" Posey pressed, drawing chuckles from the hearing room. "The answer to you is, if it's coming in three weeks, pray," Bolden said.

Comforting! But why should we pray instead of, say, shooting it from the sky with a laser?

He said Americans might want the government to be able to zap asteroids -but the government has not provided the money to do so.

"We are where we are today because you all told us to do something - and between the Administration and the Congress ... the funding did not come," he said.

Good to know. But if NASA did have the money, what would it be used for? Depends. White House science advisor John Holdren wants to put a satellite in orbit near Venus, to monitor for approaching meteors. Bolden, the NASA guy, supports President Obama's goal of placing real, live astronauts on an actual asteroid by 2025, which is the much cooler and costlier option.

Obama's 2013 budget request sought roughly $20 million for asteroid protection compared to current funding of $4 million a year.

Holdren said that adequate asteroid protection would cost $100 million a year, up to the $2 billion through 2025 sought for the manned asteroid shot.

The hearing was inspired by the meteor that exploded over Russia last month. Speaking of the Russian meteor, witnesses at today's hearing said astronomers were unable to track the 17-meter-wide space rock because it was backlit by the sun, a disclosure that, again, isn't very comforting.

Nasa's advice on asteroid hitting Earth: pray

Charles Bolden, the chief of the Nasa, has warned that the US space agency's best advice on how to handle a large asteroid heading towards New York City is "pray".

Mr Bolden told US lawmakers that prayer was all that the US or anyone could currently do about unknown asteroids and meteors that may be on a collision course with Earth.

An asteroid estimated to be have been about 55 feet (17 metres) in diameter exploded on Feb 15 over Chelyabinsk, Russia, generating shock waves that shattered windows and damaged buildings. More than 1,500 people were injured.

Later that day, a larger, unrelated asteroid discovered last year passed about 17,200 miles (27,681 km) from Earth, closer than the network of television and weather satellites that ring the planet.

The events "serve as evidence that we live in an active solar system with potentially hazardous objects passing through our neighborhood with surprising frequency," said Representative Eddie Bernice Johnson, a Texas Democrat.

"We were fortunate that the events of last month were simply an interesting coincidence rather than a catastrophe," said US House of Representatives Science Committee chairman Lamar Smith, a Texas Republican.

Mr Smith called a hearing on Tuesday to learn what is being done and how much money is needed to better protect the planet.



Nasa has found and is tracking about 95 percent of the largest objects flying near Earth, those that are .62 miles (1 km) or larger in diameter.

"An asteroid of that size, a kilometer or bigger, could plausibly end civilization," White House science advisor John Holdren told legislators at the same hearing.

But only about 10 percent of an estimated 10,000 potential "city-killer" asteroids, those with a diameter of about 165 feet (50 meters) have been found, Mr Holdren added.

On average, objects of that size are estimated to hit Earth about once every 1,000 years.

"From the information we have, we don't know of an asteroid that will threaten the population of the United States," Mr Bolden said. "But if it's coming in three weeks, pray."

In addition to stepping up its monitoring efforts and building international partnerships, Nasa is looking at developing technologies to divert an object that may be on a collision course with Earth.

"The odds of a near-Earth object strike causing massive casualties and destruction of infrastructure are very small, but the potential consequences of such an event are so large it makes sense to takes the risk seriously," Mr Holdren said.

About 66 million years ago, an object 6 miles (10 km) in diameter is believed to have smashed into what is now the Yucatan Peninsula in Mexico, leading to the demise of the dinosaurs, as well as most plant and animal life on Earth.

The asteroid that exploded over Russia last month was the largest object to hit Earth's atmosphere since the 1908 Tunguska event when an asteroid or comet exploded over Siberia, leveling 80 million trees over more than 830 square miles (2,150 sq km).
