Dear Friends,

A paper, which present a detailed analysis of the Odessa crater, Texas
has been published in the journal of “International Journal of Impact
Engineering”. The paper is:

Littlefield, D. L., P. T. Bauman, and A. Molineuxc, 2007, Analysis
of formation of the Odessa crater. International Journal of Impact
Engineering. vol. 34, no. 12, pp. 1953–1961.

In an hydrodynamics codes analysis, which integrated the geotechnical
(mechanical) properties of the target material along with details of the
topology of the crater, this study concluded:

1. The crater resulted from a near-grazing impact at very high obliquity,
likely greater than 60 degrees;

2. The depth-to-diameter ratio of the Odessa crater “is in a range
that can be reproduced only with a high-obliquity impact";

3. The meteorite likely came from either the southwest or northeast;

4. meteorite impact energy was more than 50 times larger than
originally estimated.

and 5. the meteor diameter was much larger than 2 meters.
