SPACE KNOWLEDGE was originally authored as a NASA publication in the year 1989 in an interactive format (HyperCard) and included as part of the HyperCard version of the SPACE EDUCATORS' HANDBOOK. Later, a PC version was included in the Windows 3.1 version of the SPACE EDUCATORS' HANDBOOK. The Internet version of SPACE KNOWLEDGE includes most of the same information contained in the previous two computer versions.

Jerry Woodfill, NASA Johnson Space Center, edited and authored SPACE KNOWLEDGE as an interactive program for MACINTOSH (1989) and PC WINDOWS (1992) computers as well as an HTML World Wide Web version (1996).
