Tick, Tick, Tick, Tick, Tick, Tick, Tick: 60 Minutes’ Cooper nails NASA’s Yeomans and Chodas on common asteroid threat

We all know the Tusk enjoys the study of past catastrophes but is less interested in blogging on space borne threats to our future. The intellectual real estate of future apocalypse — Repent! — is too well populated on the internet for us.

But great TV is great [...]

Two Ivies in two months confirm YD impact: Pinter of Southern Illinois – Carbondale to NBC: “Fringe science,” questions integrity of National Academy of Sciences

A meteor or comet impact near Quebec heaved a rain of hot melted rock along North America’s Atlantic Coast about 12,900 years ago, a new study claims.

Scientists have traced the geochemical signature of the BB-sized spherules that rained down back to their source, the 1.5-billion-year-old Quebecia terrane in northeastern Canada near the Gulf [...]

Linked?: Andrew Cooper on Feb 15 Asteroid and Russian Meteor

 

Cooper?

Debunked:

Not to be taken seriously. The first thing I noticed was a schoolboy blunder in  celestial mechanics:  you don’t add velocities in the way that he did, you add energies, that’s to say the squares of the velocities.  If an asteroid with an asymptotic approach speed of 5.6 km/s is going [...]

Finally Available in PNAS: Very High Temperature Impact Melt Products: Evidence for Cosmic Impacts \ Airbursts 12,900 years ago

These scientists have identified three contemporaneous levels more than 12,000 years ago, on two continents yielding siliceous scoria-like objects (SLO’s),” said H. Richard Lane, program director of National Science Foundation’s Division of Earth Sciences, which funded the research. “SLO’s are indicative of high-energy cosmic airbursts/impacts, bolstering the contention that these events induced [...]

Kerr on Limb: Science writer misleads peeps in public post

Distinguished Science writer Dr. Richard Kerr walked the plank this afternoon in response to this morning’s Knight Science Journalism Tracker inquiry of science writers.

Charles Petit’s casual post brought quick attention from the old-school dean of science writing. Kerr implored his press colleagues to, in effect: Move on, move on…There is nothing to see here.

Rohrabacher keeps eyes to the sky whilst others pols dawdle

Two great Americans

We need to take the next step. Our NEO search and tracking program continues to move forward, but nobody is taking responsibility for protection. I am more confident than ever in our ability to identify potential threats from asteroids and comets, but it is critical to [...]
