5th Planetary Crater Consortium Meeting August 6-8, 2014

5th Planetary Crater Consortium Meeting
August 6-8, 2014
US Geological Survey, 2255 N. Gemini Drive, Flagstaff, AZ

Venue:
The 5th Planetary Crater Consortium (PCC) Meeting will be held in the Building 6 (Shoemaker Center for Astrogeology) Roddy conference room at the US Geological Survey in Flagstaff, AZ, Wednesday August 6 through Friday August 8, 2014. The meeting will include time for contributed
oral and poster presentations and sufficient time for general discussion topics. You do not have to present an oral or poster presentation in order to attend the meeting.

We strive to keep the PCC meetings informal and set aside much of the time for general discussion. Dress is casual (as it is throughout Flagstaff), so leave the neckties and nylons at home. As noted below, weather in Flagstaff in mid August is warm (but not hot like the desert) and wet, so plan accordingly.

Registration:
There is no registration fee for the PCC meeting. However, please email Nadine Barlow by July 25, 2014, to let us know if you will be attending so we can plan accordingly for refreshments, etc.

Abstracts:
All participants are strongly encouraged to submit an abstract to the meeting. ABSTRACT DEADLINE IS FRIDAY, JULY 25, 2014, 5:00 PM PDT/MST. Abstracts should be 2-page, single-spaced, LPSC style format. Please submit your abstract in PDF (preferred) or Microsoft Word format to Nadine Barlow. Please indicate whether you are requesting an oral or a poster presentation, or if the abstract is "print only". Abstracts will be posted on the PCC website by Friday, August 1, 2014.

ABSTRACT
Meteorites have traditionally been defined as solid objects that have fallen to Earth from space. This definition, however, is no longer adequate. In recent decades, man-made objects have fallen to Earth from space, meteorites have been identified on the Moon and Mars, and small interplanetary objects have impacted orbiting spacecraft. Taking these facts and other potential complications into consideration, we offer new comprehensive definitions of the terms "meteorite,""meteoroid," and their smaller counterparts:
A meteoroid is a 10-μm to 1-m-size natural solid object moving in interplanetary space. A micrometeoroid is a meteoroid 10 μm to 2 mm in size.
A meteorite is a natural, solid object larger than 10 μm in size, derived from a celestial body, that was transported by natural means from the body on which it formed to a region outside the dominant gravitational influence of that body and that later collided with a natural or artificial body larger than itself (even if it is the same body from which it was launched). Weathering and other secondary processes do not affect an object's status as a meteorite as long as something recognizable remains of its original minerals or structure. An object loses its status as a meteorite if it is incorporated into a larger rock that becomes a meteorite itself.
A micrometeorite is a meteorite between 10 μm and 2 mm in size. Meteorite–"a solid substance or body falling from the high regions of the atmosphere" (Craig 1849); "[a] mass of stone and iron that ha[s] been directly observed to have fallen down to the Earth's surface" (translated from Cohen 1894); "[a] solid bod[y] which came to the earth from space" (Farrington 1915); "A mass of solid matter, too small to be considered an asteroid; either traveling through space as an unattached unit, or having landed on the earth and still retaining its identity" (Nininger 1933); "[a meteoroid] which has reached the surface of the Earth without being vaporized" (1958 International Astronomical Union (IAU) definition, quoted by Millman 1961); "a solid body which has arrived on the Earth from outer space" (Mason 1962); "[a] solid bod[y] which reach[es] the Earth (or the Moon, Mars, etc.) from interplanetary space and [is] large enough to survive passage through the Earth's (or Mars', etc.) atmosphere" (Gomes and Keil 1980); "[a meteoroid] that survive[s] passage through the atmosphere and fall[s] to earth" (Burke 1986); "a recovered fragment of a meteoroid that has survived transit through the earth's atmosphere" (McSween 1987); "[a] solid bod[y] of extraterrestrial material that penetrate[s] the atmosphere and reach[es] the Earth's surface" (Krot et al. 2003).
