Dear Colleagues:

Attached for your information is the preliminary agenda for the 3rd MER Landing
Site Workshop scheduled for March 26th-28th at the Embassy Suites in
Pasadena-Arcadia, CA

The goal of the third workshop is to make recommendations concerning which
two landing sites/regions are the highest priority based on consideration
of all information that is available regarding their science potential and
safety. The agenda includes presentations on surface characteristics and
safety considerations as well as MER mission relevant science that can be
accomplished within the landing ellipses.

All speakers are expected to provide an electronic version of their
presentation materials for posting on the landing site websites
before the workshop.

The workshop will be held at the Embassy Suites in Pasadena-Arcadia, CA

211 East Foothill Blvd.

Arcadia, CA 91006

Ph: 626/445-8525. Contact Reservations

A block of rooms at the hotel are being held:

Refer to JPL-Third Mars Landing Site

Cut-off Date for taking advantage of the room block: 3/8/02
The web site for the hotel is;jsessionid=FFZZ1H3WSBMWJJ31AOR2JLQ?ctyhocn=LAXHDES).

Your continued participation is critical to the success of the landing site
selection process and we hope that you will be able to attend and
participate in the March workshop. A final agenda will be
distributed in March.
