Clayton's Craters and other cool stuff in the Sahara

I haven’t blogged in a few days while investigating the odd features of the Egyptian-Libyan Sahara. I first started poking around this subject following the announcement of the fresh and appetizing Kamil Crater in the central-western Egyptian Sahara. This got me to looking into the subject of other purported craters in the Sahara. I had no idea that a controversy has brewed for…

Rohrabacher keeps eyes to the sky while 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 the future of humanity that we develop the capabilities to protect ourselves from those…

Breaking: WISE mission misleads public with confusing comet stats

In my day work I am no stranger to government bureaucracies and “programs” manipulating information about their activities until it suits them to do otherwise. The WISE mission is no different. In March of this year David Shiga wrote an obviously informed article revealing early results of the WISE mission (below). Six weeks into WISE’s work, someone revealed to Shiga (I…

Perigee Zero: Carolina Bays in the Midwest

I had the good fortune to meet Michael Davias, the author of the Perigee Zero website, at the AGU Fall meeting last December. Mike has taken the Bay phenomena on-line better than anyone — including me. He has also been fearless in his (well considered) speculation. I have long intended to get Perigee Zero properly linked and posted on the Tusk. I am particularly interested in posting…

Adults in Charge?: NASA #2 Lori Garver published Neo-Catastrophist!

The frequency of impacts of objects of various sizes is known only to limited precisions. In particular, objects up to several meters in diameter explode in the atmosphere without reaching the surface. Although the energy released in these explosions may be many times greater than that released by the Hiroshima bomb, they most frequently occur over the ocean or sparsely inhabited regions of Earth…

Morrison of NASA disputes Younger Dryas Impact Team -- touts Tusk despite obscurity

Unfortunately, the overcrowded session ran late, and there was no time for discussion or questions. Even when their conclusions were challenged, most of the scientists in the audience chose not to respond. The result was a lost opportunity for real debate. Perhaps not surprisingly, the AGU session received very little press attention. Indeed, following the AGU and GSA meetings, the…
