Orbiting the Earth at an altitude of 800 km Nasa's SeaWinds radar despite minor glitches earlier in the year is performing well and is returning excellent data. There had been problems with the spacecrafts inertial reference gyroscopes. The gyroscopes are used to orientate the satellite. 1, record 1, English, - inertial%20reference%20gyroscope

Gyros de références inertielles : Admettons que le montage de Cardan est idéal et le centrage de O parfait, c'est-à-dire que O est à la fois le point de croisement des axes des articulations et le centre d’inertie du gyro. Dans ces conditions en l'absence de tout couple moteur le gyro ne reçoit aucun couple et donc son axe reste inertiellement fixe. 1, record 1, French, - gyro%20de%20r%C3%A9f%C3%A9rence%20inertielle

[...] les gyroscopes qui servent à maintenir l’orientation de la station ont été surveillés pendant toute la journée. L’orientation de l’ISS [International Space Station - Station spatiale internationale] est désormais pilotée par les gyroscopes inertiels du laboratoire Destiny et non par les propulseurs du module russe Zvezda. 4, record 1, French, - gyro%20de%20r%C3%A9f%C3%A9rence%20inertielle

Because the gyroscope is supported as a pendulum, the support point, the center of mass of the gyroscope, and the center of the earth tend to lie along the same straight, vertical line. 4, record 2, English, - center%20of%20mass%20of%20the%20gyroscope
Record number: 2, Textual support number: 2 CONT
Gravity acting on the center of mass of the gyroscope causes a torque at the gyroscope's point of contact with the surface on which it is resting. If you spun the gyroscope perfectly vertically, it wouldn't do that (until friction perturbed it) because the force would be acting directly through the center of mass, nor would it precess like that if it were in free fall (because it is not in contact with any surface capable of inducing a torque). 5, record 2, English, - center%20of%20mass%20of%20the%20gyroscope

En pratique, le gyroscope est formé par un disque installé dans une monture à cardan qui permet la liberté de mouvement dans toutes les directions. Si le gyroscope est bien équilibré, c’est-à-dire si son centre de masse est exactement au centre de la suspension, son axe de rotation conservera sa direction par rapport aux étoiles fixes. 4, record 2, French, - centre%20de%20masse%20du%20gyroscope

The anomalous spacecraft spin, initially about the roll axis, will have transferred into the axis of maximum inertia, approximately along the spacecraft yaw axis. During this tumbling motion, the angular momentum vector remains inertially fixed approximately along the SOHO sun axis that existed at the time of the anomaly. This orientation results in the solar arrays being nearly edge-on to the sun and thus not generating power. 1, record 3, English, - inertially%20fixed
