Lunar Swirls Workshop Without Walls

September 7, 2011 @ 8:30 am PDT - 3:00 pm PDT

Background on Lunar Swirls

New Measurements

Swirls are among the most puzzling features on the surface of the Moon. We are hosting an informal one day Workshop without Walls on lunar swirls using NASA Lunar Science Institute (NLSI) remote communications tools.

Their bright, looping patterns are unlike anything seen in the solar system. The origin of the lunar swirls has been discussed for many years, but a universally accepted explanation for their formation remains elusive.

Current space missions are returning new views of the lunar swirls, at resolutions and wavelengths never before considered. These new data have the potential to provide tremendous new insights into swirl formation. We are therefore hosting an informal one day Workshop without Walls on lunar swirls using NASA Lunar Science Institute (NLSI) remote communications tools. The purpose of this workshop is to discuss recent advances in the study of lunar swirls. There will be invited and submitted talks, as well as time for informal discussions. The schedule will be as follows:

Please register for this workshop at


Registration will remain open through the end of the workshop.


Presenters for the Lunar Swirls workshop will be connecting through a Video Teleconferencing System for audio/video transmission as well as a computer through Adobe Connect (http://connect.arc.NASA.gov/lsw) for presentation sharing. If a presenter cannot connect through a video teleconferencing system such as Polycom, LifeSize, etc., then a toll free international teleconferencing line will be made available for audio and a webcam through Adobe Connect will be used for video (listed below).

Non-presenters will be able to participate in the workshop by logging in as a “Guest” to http://connect.arc.NASA.gov/lsw. Audio, video and screen sharing will be broadcast out to the viewers. Questions will be asked through the chat window and relayed to the Presenter by a moderator.
