Our aim is to have an informal, focused debate on two major themes:

• What are the scientific questions weak lensing can uniquely address (as opposed to simply confirming results from other techniques)? How do we raise the credibility of lensing results so others will appreciate the exciting possibilities?
• What are the new opportunities being proposed and how will these address the scientific questions above? What are the relative merits of ground and space based missions? Do they offer complementary opportunities and what are their respective technical challenges? How can we learn from other ground and space-based missions?

As you will see from the program below, we have left LOTS of time for discussion. To focus things, however, the LOC has taken the liberty of identifying possible contributors alongside key questions.

If your name is listed and you are puzzled as to what you might say, foremost relax - this is a small collegial group of lensing specialists! But feel free to phone or email one of the organizers if you need more input or would rather contribute to some other point.

If your name is not listed, not to worry. There will be plenty of time for you to have your say! However, remember we are focusing on the future not so much on recent results.

 We realize it is helpful to set the scene by discussing contemporary weak lensing results but we feel this is best done via posters rather than in the meeting itself. Accordingly, we are providing space outside the lecture theatre for posters displaying recent results. Please let Diane (dsf@phobos.caltech.edu) know the title and space required ASAP.

 The workshop is jointly sponsored by Caltech and JPL. For those who requested resources, you may be contacted by both JPL and Caltech secretaries. If there is any confusion, please contact me directly.

Richard Ellis, for the LOC
