QUESTION: What happened when you first tested the probe? ANSWER from Greg LaBorde on January 2, 1996: I've been trying to think of an answer to this. The problem is that the Probe was first tested more than 10 years ago. And of course the various components within the Probe were tested first, then higher and higher levels of assembly until finally the complete Probe was tested. In addition, there are many different kinds of tests: functional tests, where the basic functions of the Probe are tested; performance tests, where the Probe engineers check to see how _well_ the Probe's systems function, and what the limits on their performance are; Environmental tests, where the Probe is exposed to heat, cold, vacuum, shock, G-force, etc. and its ability to function during and afterwards checked. Also, _during_ the flight from Earth to Jupiter, the Probe had several "tests" in the form of checkouts to verify that it was still behaving as expected. Finally, December 7th the Probe experienced its ultimate test (and passed with FLYING COLORS!!). ________________________________________________________________________ ADDENDUM from Dan Carlock on January 2, 1996: Various organizations were involved in these pre-launch tests, as follows: Hughes Subsystem, system and environmental tests JPL Spacecraft-level integration tests Sandia Labs Entry Deceleration Test White Sands (Parachute Verification Test: "drop test")
