Slate: NASA must do more to prepare for catastrophic asteroids

WASHINGTON — About midafternoon Friday (Eastern time), a 160-foot asteroid known as 2012 DA14 will whip by the Earth, 17,000 miles (27,000 kilometers) above the Earth's surface. The asteroid poses no danger to anyone — its trajectory is well known, and it will miss the Earth. But it "poses no danger" in the same way that a gun fired a half-inch above your head does. If you were absolutely certain of the trajectory of the bullet and knew that it wouldn't hurt anyone else nearby, and there was nothing you could to stop it anyway, you could be comfortable in the knowledge that it would not affect you at all.

But it doesn't make much sense to ignore the shot entirely.

Impacts of large asteroids on Earth are rare. Asteroids the size of Friday's would cause only localized damage. The orbits of larger objects are better known, and so imminent danger of mass extinction is low. It is unlikely that astronomers will soon discover a "potentially hazardous asteroid" (PHA) high on what astronomers have dubbed the Torino scale. Still, NASA is not doing nearly enough to prepare for that unlikely eventuality.

What should be NASA's most important task — keeping the Earth, and America, safe from asteroid and comet impact — is barely mentioned in its latest strategic plan, released earlier this week. Planning for a mission to deflect a potential cataclysm is left to private organizations like the B612 Foundation, in which a number of engineers and scientists with years of experience with NASA are involved. It's even headed by former astronaut Ed Lu. But this is too important a task to be left to philanthropists and retirees like the B612 crowd. However laudable their efforts, they lack the resources and capability that the government has. Keeping its citizens safe is the foundational responsibility of government. And in this respect, NASA has been heedless of its responsibilities.

  • Is English getting dissed?

    Is the English language being massacred by the young, the linguistically untidy and anyone who uses the Internet? Absolutely.
    Is that anything new? Hardly.
    Many words and expressions in common parlance today would have raised the hackles of language scolds in the not-so-distant past. For evidence, let’s look at some examples from recent newspaper articles.

  • 'Too big to fail' equals 'too eager to borrow'

    Four years ago this month, President Barack Obama signed the Dodd-Frank Act into law, promising that the 848-page financial law would “put a stop to taxpayer bailouts once and for all,” he said. But recently, Massachusetts Sen. Elizabeth Warren told a Detroit crowd that “the biggest banks are even bigger than they were when they got too big to fail in 2008.”
    Who’s right?

  • Film critic Turan produces book

    Kenneth Turan, who is the film critic for National Public Radio’s “Morning Edition,” has written a book “Not to be Missed, Fifty-Four Favorites from a Life Time of Film.” His list of movies span the gamut from the beginnings of filmmaking through the present day.
    There are some surprising omissions on his list. While he includes two films, “A Touch of Evil” and Chimes at Midnight” made by Orson Welles, and one, “The Third Man,” that Welles starred in but did not direct. He did not however, include “Citizen Kane,” that was the first movie Welles made, that is  often cited by both film critics and historians as a favorite film.

  • Logan County’s disputed zone

    Watchers of “Star Trek” may recall the episode from the original series entitled, “Day of the Dove.” In this episode, Captain Kirk and his crew are forced by a series of circumstances into a confrontation with the Klingons. The conflict eventually resolves after Kirk realizes that the circumstances have been intentionally designed by an alien force which feeds off negative emotions, especially fear and anger. Kirk and his crew communicate this fact to the Klingons and the conflict subsides. No longer feeding upon confrontation, the alien force is weakened and successfully driven away.

  • Healthier and Wealthier? Not in Oklahoma

    Increased copays, decreased coverage, diminished health care access, reduced provider budgets and increased frustration are all the outcomes of the Legislature’s 2014 health care funding decisions. Unlike some years in the past when a languishing state economy forced legislators into making cuts, the undesirable outcomes this year could easily have been avoided.

  • Medicaid reform a necessity

    Historically, education spending by the state of Oklahoma has been the largest budget item. This is no longer the case. In recent years, the state of Oklahoma spends more on Medicaid (operated by the Oklahoma Health Care Authority) than common education and higher education combined, according to the state’s Comprehensive Annual Financial Report.

  • Remembering lessons from 1974

    This week marks the 40th anniversary of an important milestone in America’s constitutional history. On July 24, 1974, the Supreme Court voted 8-0 to order the Nixon White House to turn over audiotapes that would prove the president and his close aides were guilty of criminal violations. This ruling established with crystal clarity that the executive branch could not hide behind the shield of executive privilege to protect itself from the consequences of illegal behavior. It was a triumph for the continued vitality of our constitutional form of government.

  • RedBlueAmerica: Is parenting being criminalized in America?

    Debra Harrell was arrested recently after the McDonald’s employee let her daughter spend the day playing in a nearby park while she worked her shift. The South Carolina woman says her daughter had a cell phone in case of danger, and critics say that children once were given the independence to spend a few unsupervised hours in a park.
    Is it a crime to parent “free-range” kids? Does Harrell deserve her problems? Joel Mathis and Ben Boychuk, the RedBlueAmerica columnists, debate the issue.
