  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 May 31-June 3, 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
    * variations in oxygen isotopic composition or oxidation state with
      time on asteroids
    * "space weathering" as a complicating factor in interpretation of
      asteroid surfaces

This list is not comprehensive; contact one of the conveners with your
ideas that address the fundamental goals of the oxygen initiative. We
are always happy to have someone help us with our work!


  The four-day workshop will consist of seven oral sessions, with
Thursday afternoon (June 2) free. Morning sessions will nominally be
scheduled from 8:30 a.m. until noon, and afternoon sessions will be
scheduled 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 a
20-minute invited presentation to provide an introduction and
background. These will be followed by eight to ten 10-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. We intend to hold speakers to their allotted
times (10 or 20 minutes) for the formal presentation, but will allow the
discussion to continue as long as useful interchange of ideas is occurring.

Please note that the number of oral presentations will be limited to
encourage and facilitate discussion. Preference for oral presentation
will be given to those participants discussing general themes, as
opposed to specific research results.

A poster session will be held on Wednesday, June 1, in the evening.
Posters will remain on display throughout the entire meeting.


  The workshop will be held at the Radisson Woodlands Hotel, 1175 W.
Route 66, Flagstaff, Arizona (800-333-3333; www.radisson.com/flagstaffaz
<http://www.radisson.com/flagstaffaz>). Flagstaff is located in
north-central Arizona on the beautiful Kaibab Plateau. 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

At present, no scheduled activities are planned for the free afternoon,
although the conveners are investigating the possibility of an organized
tour of some sort. However, there is plenty to do in the general
vicinity of Flagstaff. More information can be found at

will be made available with succeeding workshop announcements.


  The Radisson Woodlands Hotel is holding a block of 75 rooms for this
workshop at a special daily rate of $67.00 plus applicable taxes
(10.118% total tax for state and local), single or double occupancy. To
ensure a room, reservations must be made by May 10, 2005.

Room Deposit: A one-night's deposit per room is mandatory to ensure a

Cancellations: The deposit is refundable if cancellation is prior to
4:00 p.m. on the day of arrival.

Guests may reserve a room by calling 1-928-773-8888. Refer to
Promotional Code Lunar and Planetary Institute.

The Radisson Woodlands Hotel is located approximately two miles from the
Amtrak Station and four miles from the Flagstaff Pulliam Airport and can
be easily reached from the airport by courtesy shuttle bus.


  Moderate funds may be available to students, recent graduates, and
postdoctoral fellows. Information regarding travel assistance will be
included in the second announcement.


  Further details regarding the workshop, including guidelines for
abstract submission and opportunities for participation, will be
included in the second announcement available on this Web site around
March 1, 2005.
