complete and some modification may still be possible. The 

 selected instrumentation is detailed in Appendix B. 



Lyman Far Ultraviolet Spectroscopy Explorer (LYMAN) (1995). 

 Potential Explorer-class mission if collaboration can be secured 

 to provide cost-sharing. A strawman instrument complement has 

 been defined for planning purposes, no AO has yet been issued. 

 The strawman instrument complement is listed in Appendix B. 



Initial Configuration for the Space Station (1995). Phase A 

 studies of the Block I Space Station have been completed. The 

 final definition of the module structures and positioning and the 

 selection of the instrumentation associated with these modules is 

 expected to be completed during 1988. 



Space Infrared Telescope Facility (1996) [Ames Research Cen- 

 ter] . The instrument complement has been selected on the basis 

 of a competitive AO, but implementation is not yet complete and 

 some modification may still be possible. The selected instrumen- 

 tation is detailed in Appendix B. 



Large Deployable Reflector (2000) [Jet Propulsion Laboratory 

 and Ames Research Center] . In preproject phase, waiting phase A 

 study monies. Strawman instrument complement detailed in 

 Appendix B. 



Orbiting Very Long Baseline Interferometry (1998) [Jet Propul- 

 sion Laboratory]. Possible Explorer-class mission. In preproject 

 phase, awaiting phase A study monies. Strawman instrument 

 complement detailed in Appendix B. 



AIRBORNE 



KAO 



Kuiper Airborne Observatory (now) [Ames Research Center]. 

 Telescope is a permanent fixture; new backends are supplied by 

 each observer. 



3M Balloon Balloon-Borne Three-Meter Telescope for Far-Infrared and Sub- 

 millimeter Astronomy (1989) [Smithsonian Institution Astro- 

 physical Observatory, University of Arizona, and University of 

 Chicago]. One of three balloon programs under consideration. 

 The instrument complement is finalized and is detailed in Appen- 

 dix B.
