White House, NASA want help hunting asteroids

WASHINGTON — The White House and NASA on Tuesday will ask the public for help finding asteroids that potentially could slam into the Earth with catastrophic consequences.

Citing planetary defense, the administration has decided that the search for killer rocks in space should be the latest in a series of "Grand Challenges," in which the government sets an ambitious goal, helps create public-private partnerships and sometimes offers prize money for innovative ideas.

"This is really a call to action to find all asteroid threats to human populations and know what to do about them," NASA Deputy Administrator Lori Garver said Monday. She said the asteroid hunt would help prove that "we're smarter than the dinosaurs."

There is a second, overlapping agenda at work here: The NASA human spaceflight program needs to find a target rock for what is now being called the Asteroid Redirect Mission (formerly the Asteroid Retrieval Mission), or ARM.

The proposed mission, which is early in the planning stages, would send astronauts to visit an asteroid that had been redirected into a high lunar orbit. But first a robotic spacecraft would have to rendezvous with the asteroid and capture it. And even before that, scientists would have to find the right asteroid.

The target rock has to be moving at a leisurely pace relative to the Earth, and ideally would come close to the Earth-moon system sometime in the early 2020s. At present, NASA has a short list of possible targets, but all need further scrutiny to see if they have the size, shape, spin rate and composition that the asteroid mission would require.

Two recent feasibility studies used as their reference a rock discovered in 2009, but NASA scientists aren't sure that it will meet the mission requirements. For one thing, it might turn out to be too small. They plan to study it this fall with the Spitzer Space Telescope.

    Do you remember when Starbucks was cool? It opened in Seattle in the 1970s as a local specialty roaster, a trendy alternative to the prevailing generic swill. But the price of conquest is cachet. What was once novel — the warm décor, the gentle music, the faux-Italian lingo — has become banal. Today's coffee snobs would rather snort Sanka than set foot inside a Starbucks
