didn't know this: ( - blasted budget constraints .. )

In the past, NASA spacecraft have had scan platforms (moving platforms) which allow remote sensing instruments such as cameras to take images while simultaneously transmitting that data to Earth. Faced with budgetary cuts before launch, Cassini team members discarded the scan platform option. Without the scan platform, Cassini engineers had to bolt the remote sensing scientific instruments to fixed positions on the spacecraft. As a result, the entire spacecraft must first point to its target, then point back to Earth to transmit data.
