> Cassini completed its closest flyby of the odd moon Iapetus on Sept. 10,
> 2007. The spacecraft flew about 1,640 kilometers (1,000 miles) from
> Iapetus' surface and is returning amazing views of the bizarre moon.
>
> All the data were successfully recorded on the spacecraft. Twenty-one
> minutes into the first post-flyby data downlink, the spacecraft went
> into a precautionary condition called "safe mode. The cause has been
> determined to be a solid state power switch that was tripped due to a
> galactic cosmic ray hit.
>
> While in safe mode, the spacecraft turns off all unnecessary activities
> and transmits only essential engineering telemetry at a low data rate,
> while it awaits commands from Earth.
>
> Tuesday morning, Sept. 11, commands were sent to the spacecraft to
> resume high rate science and engineering data playback. The project
> expects all data on the spacecraft will be returned to Earth during
> downlinks on Tuesday and Wednesday, with no impact on the Iapetus
> science data return beyond a brief delay.
>
> Due to the safing event, the sequence executing on the spacecraft was
> halted, and Cassini's instruments will not be turned back on for three
> or four days. The last time Cassini was in safe mode was over four years
> ago.
