Bad news for PFS. I hope they will be able to solve this issue. sad.gif

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.

For those that have not seen the BBC series 'The Planets' - a Venera scientists recalled the problem being described thus

Senior Engineer "I believe we have landed in something sticky and viscous"
Junior Engineer "Yes sir, in the sh**"
