Klaus, Michael Wong, Jean-Pierre Lebreton, Neil Bowles	Titan''s Greenhouse Effect and Climate	Herein we examine the atmospheric parallels between the Earth and Titan including the possibility of dramatic climate change.

David E. Smith	A budget phasing approach to Europa Jupiter System Mission Science	Due to budget constraints, the proposed Europa Jupiter System Mission is unlikely to occur as planned.
