Bad news for PFS. I hope they will be able to solve this issue.
![]() The PFS scanner is stuck in its closed position. Several attempts to move it were made at the time, but the instrument did not respond. Experts suspected a thermal problem by which low temperatures were blocking the rotation of the mechanism. Another attempt to move the scanner was made on 16 March 2006, in warmer flight conditions. Unfortunately, the scanner remains stuck. The next opportunity to perform another test on the spacecraft will be end of April, after the Venus Orbit Insertion.

Boys - don't make me come in here!! Inappropriate politics removed.
I'm amazed you've not had a dig at something/someone about this one though Bruce - deployment of devices in space is something you've enjoyed lambasting in the past ( based on Galileo and MEX ) Doug |

In a worse case scenario, the failure will be traced to widget xyz, and the same widget has a deployment function on New Horizions. Failures of space-based hardware need to be known and understood by the space design communtity in a timely manner, so we can look under the bonnet of anything we are building and fix it, before it hits the street. This is a space health management issue... |
