QUESTION: Is the Cassini Spacecraft Y2K compatible? ANSWER from FAQ on June 25, 1999: The Cassini Program has undergone a lengthy and thorough test program to verify that all critical ground and flight systems are Y2K compatible. The Cassini Y2K test program, conducted over the past year, consisted of code inspection, analysis, and testing. No changes were required to the spacecraft or its instruments to achieve Y2K compatibility as none of their components are date sensitive. Minor changes were required to a very limited number of components of the ground system that were inherited from previous missions; all changes have been verified to be correctly implemented.
