  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 2–3, 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 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 at http://www.desertusa.com/Cities/az/flagstaff.html or http://www.flagstaffarizona.org.

  ACCOMMODATIONS
  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 reservation.

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.

  REGISTRATION
  A fee of $200.00 ($175.00 for students) will be assessed each participant to cover workshop services. You must preregister and prepay by May 6, 2005, to avoid a $50.00 late fee.

A welcome registration reception will be held on Wednesday evening, June 1, from 5:30 to 7:00 p.m. This event, breakfasts and lunches (Thursday and Friday), meeting break refreshments, and a hardcopy volume containing the program and abstracts are all included in the registration fee.

Please return the downloadable registration form with your payment before May 6, 2005, to avoid a $50.00 late fee, or you may use the electronic registration form if paying by credit card. Foreign participants who state on the registration form that they have a currency exchange problem may pay in cash at the meeting (and avoid a $50.00 late fee) if they return the form by May 6, 2005.

Cancellations with requests for refunds will be accepted through Friday, May 20, 2005. Please note that a $25.00 fee will be charged on all cancellations.
