Final Announcement — April 2011

Meeting Location and Date

The workshop on A Wet vs. Dry Moon:  Exploring Volatile Reservoirs and Implications for the Evolution of the Moon and Future Exploration will be held June 13–15, 2011, at the Lunar and Planetary Institute, which is housed in the USRA facility at 3600 Bay Area Boulevard, Houston TX 77058.

Purpose and Scope

Since the Apollo program the Moon’s surface and its mantle generally have been considered “dry.” Recent observations have suggested different roles for volatiles on the Moon:

  • Numerous orbital missions have supported the potential for H2O ice in permanently shadowed regions of the Moon.
  • Data from the M3 mission on Chandrayaan-1 has been interpreted as indicating H2O and/or OH on much of the lunar surface outside of the shadowed regions.
  • Ion microprobe data from lunar glasses has been interpreted as indicating significant H2O in the lunar mantle.
  • Analyses of phosphates in lunar rocks suggest the existence of an OH component.
  • Chloride isotope data has been interpreted as indicating volcanic gases escaping during the eruption of lunar basalts were very low in H.

All these observations have given us a fundamentally new view of our Moon.

The purpose of this workshop is to bring together members of the planetary science community to discuss and integrate mission observations, laboratory measurements, and theoretical models for the volatile behavior and reservoirs on the Moon, their potential role in shaping the evolution of the Moon, and implications for future robotic and human exploration of the Moon. The workshop will also examine the potential scientific importance of sealed Apollo samples that could shed light on these observations and how they should be studied within the context of a well-thought-out sample consortium.

Meeting Format

The workshop will consist of five plenary sessions and a poster session over a period of 2.5 days. More detailed information is available by viewing the program and abstracts. Authors can determine where their abstract has been scheduled by viewing the author index.

The meeting venue can accommodate up to 120 participants. In the event that this workshop is oversubscribed, participants will be selected by date of registration.

Student Travel Grants

A small number of travel grants are available to support undergraduate and graduate student travel to the Lunar Volatiles Workshop. Students who currently have no other travel support are encouraged to apply for a travel award. Interested students should submit their name, affiliation, and brief personal statement (no more than 250 words) to [email protected] and [email protected] (please put "Application for Student Travel Support to the Lunar Volatiles Workshop" in the subject line) explaining why you would like to attend this workshop. The deadline for application is April 29, 2011. Travel grant awardees will be notified by May 16, 2011. Travel awards are in the amount of $1000.00.


Participants are responsible for making their own travel arrangements and hotel reservations. For a list of hotels in the area, refer to Bay Area Houston Hotel Information. The location of the hotels in relation to the LPI is shown on the area map.
