Hand microphones and headsets are installed at each flight crew member station. The hand microphone is designed for close-talking, noise-cancelling applications in high noise level areas. The microphone is packaged in a small molded, black, high-impack phenolic case. A press-to-talk button is located on the upper portion of the case... Oxygen masks with microphones are installed at each flight crew member station. A push-to-talk button is installed on the captain's control wheel and on the first officer's control wheel. The push-to-talk buttons are used to control the oxygen mask microphones when transmitting on the selected communication transceiver or on the audio integrating system. 6, record 3, English, - press%2Dto%2Dtalk%20switch

... AlliedSignal has changed the way it manufactures its highly accurate gyros in an effort to stretch their service lives to prevent a future shutdown. But the basic design of the gyros has not changed, since they are about twice as accurate as the next-best gyros available, according to Hubble Program Manager John Campbell. The problem is the tiny leads that carry power to the gyro rotors. Sunk in a thick damping fluid, the hair-like wires corrode over time and break. The six new gyros Discovery's crew will install retain the fine power leads, but the damping fluid was loaded into the gyros in a manner that engineers hope kept oxygen out of the system, reducing the risk of oxidation. 5, record 5, English, - damping%20fluid

La combinaison qui protège les astronautes lors de leurs sorties dans l'espace compte parmi les plus importantes et plus complexes pièces d'équipement à leur disposition. Elle est en fait un mini-vaisseau spatial, capable de fournir tout ce qui est nécessaire à la vie et à la sécurité des astronautes pendant qu'ils travaillent dans le vide spatial. Connue officiellement sous le nom de scaphandre EMU (pour Extravehicular Mobility Unit), la combinaison est constituée de deux composantes principales : la combinaison spatiale comme telle (SSA, pour Space Suit Assembly) et le système de survie de base (PLSS pour Primary Life Support System). 4, record 6, French, - combinaison%20EMU

Dans l'usage, les termes «combinaison spatiale» et «scaphandre spatial» sont souvent utilisés pour désigner à la fois un générique, le «extravehicular mobility unit (EMU)» et un spécifique, le «space suit assembly», qui est une composante de l'EMU. Pour solutionner ce problème, lorsque l'on veut désigner l'EMU, il convient de spécifier «combinaison EMU» ou «scaphandre EMU». 3, record 6, French, - combinaison%20EMU
