      DC-X SINGLE-STAGE TO ORBIT (SSTO) PROGRAM

!     SDI's SSTO (Single Stage To Orbit) project is trying to build a fully
!     reusable spacecraft with one stage and no jettisoned parts, which simply
!     takes off and goes into orbit. This is technically demanding but is now
!     tentatively thought to be feasible, using materials developed by NASP
!     and more-or-less off-the-shelf engine technology. The objective is
!     10,000 lbs or so into low orbit at a cost of $100-300/lb with a vehicle
!     turnaround time of one week. It is being done as a high-risk fast-track
!     effort, with little publicity, a tight schedule, and a firm attempt to
!     avoid pioneering technology unnecessarily.

!     McDonnell-Douglas got the contract. They're currently building DC-X, a
!     subscale suborbital unmanned demonstrator that will check out the basic
!     concept, flying in mid-1993 (that is not a typo). They hope they will
!     then get funding for DC-Y, a full-scale orbital manned prototype. This
!     would then, with luck, lead to the DC-1, a production spaceship
!     certified to airliner-like standards for commercial service. McDD calls
!     the whole project Delta Clipper, whence the DC designations (which also
!     have some historical significance for McDD). So far, only DC-X has firm
!     funding.

      DC-X SINGLE-STAGE TO ORBIT (SSTO) PROGRAM

!     SDI's SSRT (Single Stage Rocket Technology) project has funded a
!     suborbital technology demonstrator called DC-X that should fly in
!     mid-1993. Further development towards an operational single-stage to
!     orbit vehicle is uncertain at present; for considerably more detail on
!     the SSRT program, get the document

      1992 Missions
-	  o Atmospheric Lab for Applications and Science (ATLAS) [Apr, STS-45]
-	      Shuttle, this manned lab will study variations in the solar
-	      spectrum and Earth's atmosphere.
-
-	  o Extreme Ultraviolet Explorer [May, Delta II rocket]
-	      This satellite will study the evolution and population of
-	      stars and galaxies.
-
-	  o US Microgravity Laboratory [Jun, STS-50 USML-01]
-
-	  o TOPEX/Poseidon [Jun, Ariane 4 V52 rocket]
-	      TOPEX will study the relationship of ocean systems to climate.
-	      (Someone want to fill in the lineage of this mission? Presumably
-	      it's primarily ESA.)
-
-	  o Tethered Satellite System [Aug, STS-46 TSS-1]
-	      Shuttle, attached by tether to the shuttle bay, system will
-	      study electrical fields and gas clouds in space while
