The Microgravity Science Glovebox (MSG) is a joint development project between NASA and the European Space Agency (ESA). The double rack unit is a versatile research facility designed to permit the flexibility of crew-manipulated investigations. Its configuration has been planned around the concept of an experimental workstation where a variety of experiments can be installed and operated in a fashion very similar to their operation in a ground-based laboratory. ... Specifically, the facility provides a large enclosed work volume, power, video, photography, vacuum connections, heat rejection, stowage, filtered air, gaseous nitrogen, lighting, airlock access, physical positioning and hold-down attachments, and computer data acquisition and control capabilities.  3, record 1, English, - microgravity%20science%20glovebox

The MSG [Microgravity Science Glovebox] is a containment facility designed for supporting a wide range of microgravity science investigations and demonstrations. In the sealed mode, the MSG serves as a single level of containment by providing a physical barrier. In the air circulation mode the MSG serves as a one failure tolerant containment by providing a physical barrier and a negative pressure relative to the cabin. The MSG further facilitates investigations by providing many of the resources that are typically used by microgravity science investigations.  4, record 1, English, - microgravity%20science%20glovebox

La boîte à gants permettra aux astronautes à bord de la Station spatiale internationale de procéder à de nombreuses expériences dans le domaine des matériaux, de la combustion, des fluides et de la technologie et de conduire des études sur l'environnement en microgravité. Elle devrait être lancée dans le mini-module logistique pressurisé en mai 2002. Cette installation scientifique offre un volume de travail clos et étanche ; elle est équipée de branchements pour l'éclairage, les dispositifs mécaniques, l'électricité, les données, le gaz et le vide et d'une régulation thermique pour mener à bien les expériences. On accède au volume de travail par des gants intégrés qui isolent l'expérience de l'environnement et de l'opérateur. La MSG [Microgravity Science Glovebox] est montée dans un bâti de charge utile international normalisé (ISPR) ; elle peut être utilisée en mode ouvert, l'air circulant alors du volume de travail vers la cabine de la Station spatiale, ou en mode fermé, l'air ne circulant qu'à l'intérieur de la MSG. De plus, la boîte à gants est capable de maintenir une atmosphère inerte avec de l'azote sec, le volume d'oxygène restant alors égal ou inférieur à 10 %.  2, record 1, French, - bo%C3%AEte%20%C3%A0%20gants

The calculations for the ISS [International Space Station] quasi-steady acceleration environment can be compared to a set of formal design requirements which state that 50 percent of the ISPR [International Standard Payload Rack] locations within the U. S. Lab, Columbus and the JEM must have quasi-steady accelerations below 1 ug for periods of 30 continuous days a total of 6 times per year. The operation of the Station in Microgravity Mode is designed to produce these 30 day intervals. The quasi-steady acceleration vector has an additional directional stability requirement stating that the component perpendicular to the vector's orbital average must be less than or equal to 0. 2 [mu] g. To meet this requirement the Station's attitude must be controlled during orbit so that it maintains a constant position relative to the LVLH [Local Vertical/Local Horizontal] axes.  2, record 2, English, - quasi%2Dsteady%20acceleration%20environment

The quasi-steady state acceleration level is determined primarily by the combined effects of atmospheric drag (due to the finite residual Earth’s atmosphere at the orbital altitude of the ISS), and gravity gradient stabilisation of the ISS. Gravity gradient stabilisation uses the principle that a body in orbit around the Earth will tend to rotate about it’s centre of mass, as each part of the body will tend to follow it’s own orbit. It will normally oscillate about a mean orientation, but will eventually remain in a stable orientation with respect to the Earth. The normal orientation for the ISS is the Torque Equilibrium Attitude discussed earlier. The resultant combination of atmospheric drag, gravity gradient and other secondary effects produce a set of gravity contours (i.e., locations of equal gravity level) which define the quasi-steady state microgravity environment of the ISS.  3, record 2, English, - quasi%2Dsteady%20acceleration%20environment

Les modèles d'analyse dynamique (DAC 8) pour l'ISS [International Space Station] prévoient un environnement caractérisé par des vibrations de l'ordre du milli-g (10-4 g) plutôt que des conditions de véritable microgravité (10-6 g) en raison des activités et des divers éléments de l'ISS qui causent des vibrations intempestives (gigue gravitationnelle). Les travaux antérieurs menés à bord de la navette et de Mir ont montré que le milieu est caractérisé par des vibrations aléatoires continues, orientées dans tous les sens, avec des accélérations de l'ordre du milli-g et des crêtes dépassant souvent les 10 milli-g.  2, record 2, French, - milieu%20gravitationnel%20quasi%20stable

The "Microgravity" and "Standard" operational modes are the primary modes for carrying out research activities on the ISS [International Space Station]. These two modes have been specifically defined to optimise the gravity environment of the ISS for user research activities. The Microgravity Mode, as the name suggests, provides the most optimised microgravity environment. The Microgravity Mode has been defined to ensure that : 50% of the International Standard Payload Rack locations within the European Columbus, Destiny and Japanese Kibo laboratories must have quasi-steady state accelerations less than 1 micro-g for at least 30 days continuously, on six occasions each year".  2, record 4, English, - microgravity%20mode

Mode changes are usually controlled by the ground controller or by on-orbit crew input commands, but the transition to survival mode may be automatically initiated by the ISS.... In the microgravity mode, user payload operations for microgravity research are supported. This mode does include the effects of crew equipment such as exercise devices and latched or hinged enclosures, however crew effects are mitigated to the extent possible.  3, record 4, English, - microgravity%20mode
