Observatory's science program through proposing for new observations, for 
archival research projects or for theory/modeling projects in support of 
understanding Chandra data. Participation in this program is open to all 
categories of organizations, both domestic and foreign, including 
educational institutions, profit and nonprofit organizations, NASA Centers, 
and other Government agencies. This solicitation will be open from December 
15, 2003 through March 12, 2004, 6:00pm EST, and proposals may be submitted 
throughout this period. Results of the selection are expected to be 
announced in July 2004.

Technical information on the Chandra X-ray Observatory, software tools to 
assist in planning proposals, the proposal submission software (RPS) and 
all other information concerning this CfP are available electronically from
