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.

There is no commonality between the aparant failure of the PFS cover, and MARSIS or the Huygens problem. I know you like to think outside the box, but that's just wayyy waAYy outside it

You lose five points for using the B word The only common failure mode I can see is in quality control: I don't see how a command as critical as 'switch on mains' can be dropped, if whoever is tasked with checking-off on all the software functions fills in all their little blocks. We were promised a report on this...some day. Is there any hint on the nature of the PFS problem? Electrical? Hindrence? Damage? Lazy eye virus? |
