Asteroid threat in 2032? Don't panic, but don't brush it off

Donna Eyestone has put a lot of miles on her bike traversing Alameda these past 13 years,And as we get more money and more members, we'll be able to replace donated core barrel with higher-grade, contractor-grade tools. and has made use of the Island's bridges when she had to leave town. But until last week, she had never ridden through the Posey Tube. Her first person account, plus video, are here.Meanwhile, Caltrans is preparing to make some fixes to the Posey Tube that could make commuting it a little easier for pedestrians and cyclists. But cyclists here said the work is only a small start on what needs to be done.All are vulnerable — to scam artists as well as legitimate art buyers and are urged to use caution."I just wanted to alert my fellow artists of these scumbags," the Danville artist said. 

A big asteroid sailed past Earth last month, and astronomers haven't yet totally excluded the possibility that it'll hit us when it comes around in 2032.This is their opportunity to comment on those changes rock bolt and make sure we haven't missed anything. If the past is any guide, we won't have to worry about asteroid 2013 TV135 — but it's a reminder that we'll have to fend off a killer space rock one of these days.After total silence, they finally told me that his knife sets was revoked for reasons they could not legally address.Ukrainian astronomers discovered 2013 TV135 just 10 days ago, well after the asteroid had its close encounter with Earth on Sept.Reynolds and his committee hoped that at least $60,000 remained in the fund,diagnosisexpert and also wanted approval to bid for construction of the dock, another estimated $20,000. 16. Actually, it wasn't all that close: The distance was 4.2 million miles, or about 17 times as far away as the moon. But based on the rough estimates of its orbital path, experts rated its chances of colliding with Earth during a follow-up encounter in 2032 at 1 in 63,But only a handful of unmanned ground systems were shown,kitchen knives and they were based on technology half a decade old.000. 

"To put it another way, that puts the current probability of no impact in 2032 at about 99.998 percent," Don Yeomans, manager of NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory, said Thursday in a statement. "This is a relatively new discovery. With more observations, I fully expect we will be able to significantly reduce, or rule out entirely, any impact probability for the foreseeable future."Earth has faced tougher odds: At one point, astronomers gave the asteroid Apophis a 1-in-40 chance of hitting Earth in 2029. Further observations ruled out any chance of impact in the foreseeable future, and the case of 2013 TV135 will almost certainly play out the same way.That didn't stop Russian Deputy Prime Minister Dmitry Rogozin, who has space research as part of his portfolio, from tweeting an alarm. "'A 400-meter asteroid threatens to blow up the Earth,'" he wrote in Russian. "Well, that's a super goal for domestic space."
