OPf course - not engine, b ut gyroscope (CMG). Form more technically accurate description, see: http://www.spaceref.com/news/viewsr.html?pid=15390 NASA Space Station On-Orbit Status 9 February 2005 <quote begin> After yesterday s successful attitude transition to XPOP TEA (x-axis perpendicular to orbit plane/torque equilibrium attitude) at 10:47am EST and return of control authority to the U.S. CMGs (control moment gyroscopes) at ~11:07am, an incorrect ground command caused unexpected CMG saturation (~11:26am) and loss of AC (attitude control). AC was taken over automatically by the Russian thrusters and later returned to CMG Momentum Management (~4:54pm). [The excursion cost an estimated 14 kg of propellants on top of the 9 kg for the original maneuver to XPOP.] <quote end> ================= Původní zpráva ================= Od (From): "Kevin Fetter" <kfetter@yahoo.com> Komu (To): seesat-l@satobs.org Kopie (Cc): Předmět (Subject): US Orientation Engine Fails On ISS Datum (Date): 11. 2. 2005 7:24 ================================================== < http://www.spacedaily.com/news/iss-05r.html < < < Mgr.
