4th Landing Site Workshop for the 2003 Mars Exploration Rovers

Dear Colleague:

As a reminder, the 4th Landing Site Workshop for the 2003 Mars Exploration
Rovers will be held next week, January 8-10, 2003, at the Embassy Suites
Hotel on Huntington Avenue in Arcadia, CA. A block of rooms have been
reserved at the Embassy Suites at the government rate of $99 under the name
of “JPL MER Landing”. Additional information is available at the hotel

The workshop will consider the four sites remaining under consideration:
Hematite, Gusev Crater, Isidis Basin, and the Elysium “Wind Safe” Site.
More specifically, presentations will focus on scientific hypotheses that
can be tested at a site using the Athena Science Payload or focus on issues
related to landing safety and/or rover mobility or instrument operability.
Therefore, talks related to the general geologic setting of the proposed
landing sites will emphasize distinguishing between various testable
hypotheses using the Athena Science Package It is expected that a
compilation of these testable hypotheses will comprise the outcome of the
workshop. An agenda for the workshop is attached.

A complete description of the mission/science objectives of the Mars
Exploration Rovers, all related engineering constraints, and all activities
related to the landing site selection process to date can be reviewed at: and
Attendees are encouraged to review this material prior to the workshop.

This will be the final community workshop related to selection of the
landing sites for the Mars Exploration Rovers. Following the workshop, the
Project and Science Team will formulate a recommendation to NASA
Headquarters for final landing site selection and approval.

Your continued participation is critical to the selection of the optimum
landing sites for the Mars Exploration Rovers and we hope to see you at the
workshop next week!
