Kvant-V Equipment Glitch
During the launch processing in March 2011, the Technical Management on Human Space System Flight Testing reported an operational glitch of the Kvant-V equipment. The Kvant-V system resides in the Instrumentation Propulsion Module – one of the three modules that make the Soyuz TMA-21 spacecraft. On March 13, Roscosmos Board held a meeting to discuss the issue and delayed the launch from March 30, 2011. The glitch was traced back to a faulty part (capacitor) in the equipment. Russian Space Agency Roscosmos established a working group with representatives from RSC-Energia and TSNIImash, the manufacturers and developers of the Soyuz systems. Proposals of the working group were considered during an additional General Designers’ Review led by RSC-Energia president Vitaly Lopota. After analyzing the submitted data by the Review, Roscosmos decided to set April 4 as the new launch date.

Famous quotes containing the word equipment:
“Biological possibility and desire are not the same as biological need. Women have childbearing equipment. For them to choose not to use the equipment is no more blocking what is instinctive than it is for a man who, muscles or no, chooses not to be a weightlifter.”
—Betty Rollin (b. 1936)
