Glad to answer, Chris.

Information from many scientific probes has been lost due to programming errors, usually either by setting a flag wrong or due to unintended program interactions. As a recent example, half the data from Hyugens was lost in this way.

Since these failures are usually never adequately investigated, analyzed, or reported, they keep happening again and again and again. Compounding the problem is that usually each probes' computer system is unique, and their control interfaces are usually very awkward to use, with no safety interlocks or ground emulation systems.

Fortunately in this case the error was not fatal.

I am not pleased with the targetting focus of Cassini, as the data from Saturn's moons may go a long way toward clearing up the problem of determing the occurence of cometary impact, providing that data is obtained and then analyzed.

Also, little thought appears to being given currently to out year operations. For some reason, failure before then is expected and anticipated. I would certainly like to see Cassinin either inserted into Titan orbit at the end of its fuel supplies, or perhaps sent towards the Kuiper Belt for a survey.
