| PURPOSE AND SCOPE
|
| |
The NASA Cosmochemistry Program and the Lunar and Planetary Institute are
sponsoring a five-year scientific initiative entitled "Oxygen in the Solar System: Origins
of Isotopic and Redox Complexity." The goal of the initiative is to better understand the
important cosmochemical roles of oxygen and oxygen compounds in all their
manifestations. The initiative consists of four teams: Terrestrial Planets, Asteroids and
Meteorites, Outer Planets, and Earliest Solar System Materials and Processes. A formal
announcement of this initiative appeared in the December 9, 2003, issue of Eos.
Additional information can be accessed on the LPI Web site at
http://www.lpi.usra.edu/oxygen/.
The Workshop on Oxygen in Asteroids and Meteorites, organized by the Asteroids
and Meteorites Team, will be held June 23, 2005, in Flagstaff, Arizona. The
scope of the workshop will be broad. The workshop will examine fundamental issues
regarding the chemical and isotopic distribution of oxygen in the solar system as
evidenced in asteroid mineralogy, asteroidal meteorites, and constraints from modeling.
Topics of interest will include
- mineralogy of asteroids, especially that which speaks to the distribution of
oxidation state throughout the asteroid belt
- oxygen isotopic compositions and partial pressures of parent bodies as
recorded in meteorites
- connections between oxygen isotopic composition, oxygen partial pressure,
and other parent-body characteristics, such as moderately volatile element,
carbon, and hydrogen contents, that may give clues to the distribution and
speciation of oxygen in the solar system
- asteroid processes, from low-temperature fluid-rock interactions to
magmatic differentiation, that affected their initial oxygen characteristics
- variations in oxygen isotopic composition or oxidation state with time on
asteroids
- "space weathering" as a complicating factor in interpretation of asteroid
surfaces

| WORKSHOP SCHEDULE |
| |
The two-day workshop will consist of four oral sessions. Morning sessions are scheduled from 8:30 a.m. until noon,
and afternoon sessions are from 1:30 to 5:00 p.m. In the interest of
promoting discussion, these times will remain flexible. The program will consist of both
invited and contributed talks. Each major subtopic will have 30-minute invited
presentations to provide introduction and background. These will be followed by several
15-minute talks per session, with the remaining time allotted for discussion. This
format proved highly successful at the Workshop on Oxygen in the Terrestrial Planets, held in
July 2004. We intend to hold speakers to their allotted times (15 or 30 minutes)
for the formal presentation, but will allow the discussion to continue as long as useful
interchange of ideas is occurring. For more information, refer to the online program and abstracts.
Audio-visual equipment available for oral
presentations will include one LCD projector and two overhead projectors.
NOTE: A 35-mm carousel slide projector will NOT be available.
All electronic presentations must follow workshop guidelines as detailed in the Instructions for
Electronic Presentations.

| LOCATION |
| |
The workshop will be held at the Radisson Woodlands Hotel, 1175 W. Route 66,
Flagstaff, Arizona (800-333-3333; www.radisson.com/flagstaffaz). Flagstaff is located
in north-central Arizona on the beautiful Kaibab Plateau and 142 miles (228 kilometers) from Phoenix. Most attendees will probably
arrive from Flagstaff Pulliam Airport, which is approximately 5 miles (8 kilometers)
south of downtown Flagstaff. American West Airlines' branch, America West Express,
the only commercial airline carrier flying to Flagstaff, provides air
shuttle service between Phoenix Sky Harbor International Airport and Flagstaff. Phoenix
Sky Harbor International Airport is the nearest international airport to Flagstaff and is
served by 17 major airlines and 3 commuter airlines (http://phoenix.gov/AVIATION/flts_air/index.html).
Lists of activities in the Flagstaff area can be found
