CSAR. Microgravity Sciences provided researchers and scientists from Canadian industry and universities with low-cost, high-quality microgravity flight opportunities aboard the Canadian Space Agency Rocket(CSAR), a Black Brandt rocket developed by Bristol Aerospace Ltd. The first rocket, CSAR-1, was launched in March 1992 and carried five experiments; CSAR-2 was launched in December 1994 and also carried five experiments. Both launches took place at the White Sands Missile Range in White Sands, New Mexico. The Canadian experiments onboard, subjected to six minutes of high-quality microgravity conditions, were designed to advance our understanding of the processes and behaviours of materials, which may lead Canada to improving product manufacturing on Earth and enhancing the development of erosion-resistant materials.

Nano crystal Get-Away Special(NANOGAS)-The Nanocrystal Get-Away Special(NANO-GAS) is a Space Shuttle payload designed to grow high-quality crystals of an advanced new class of materials called crystalline nanoporous semiconductors. Because of their unique absorption characteristics, these materials could find applications in high-precision lasers, computers and other high-performance electronic devices. The samples were successfully processed in May 1996 on board Space Shuttle Mission STS-77. An increase in the size and quality of nanoporous crystals can be achieved by conducting these experiments in microgravity, where the gravitational forces are minimal.

L'expérience NANOGAS (Nanocrystals Get Away Special) était une charge utile GAS destinée à la croissance de cristaux de qualité améliorée appartenant à une nouvelle catégorie de matériaux évolués appelés semi-conducteurs cristallins nanoporeux. Leur particularité réside dans leur structure atomique qui leur confère des propriétés d'adsorption uniques. Parmi les applications potentielles de cette nouvelle catégorie de matériaux, mentionnons les lasers haute précision, les ordinateurs et d'autres dispositifs électroniques hautement performants. Parrainée par le Programme des sciences en microgravité de l'ASC, l'expérience portait sur le traitement de 38 échantillons préparés par une équipe de chercheurs de l'Université de Toronto, dirigée par le professeur Geoffrey Ozin. L'expérience a volé à bord de la navette spatiale Endeavour en mai 1996. Les échantillons ont été traités dans une chambre de réaction mise au point par COM DEV Atlantic. Le fait de mener ces expériences dans un milieu qui échappe presque entièrement aux effets de la pesanteur a permis d'obtenir des cristaux nanoporeux plus gros et de meilleure qualité. En étudiant les cristaux produits en microgravité, les chercheurs espèrent un jour être capables de produire sur Terre des cristaux nanoporeux plus gros et plus purs.

The Binary Colloidal Alloy Test-3 is an Exploration Systems’ transition flight experiment in the Human System Research and Technology area. BCAT-3 provides a unique opportunity to explore fundamental physics and simultaneously develop important future technology, including computers operating on light, complex biomolecular pharmaceuticals, clean sources of geothermal power, and novel rocket engines for interplanetary travel. These studies depend entirely on the microgravity environment provided by the International Space Station(ISS) ;in all other locations accessible to science, gravity dominates and precludes investigation of any other effects of interest. The experiment itself [consists of] photographing samples of colloidal particles with a digital camera onboard the ISS. Colloids are tiny nanoscale spheres of plexiglass a thousand times smaller than the width of a human hair(submicron radius) that are suspended in a fluid. They are ubiquitous(e. g., milk, smoke, and paint) and therefore interesting to study directly. Colloids are also small enough that they behave much like atoms and so can be used to model all sorts of phenomena because their size, shape, and interactions can be controlled. The 10 samples in BCAT-3 are made from the same ingredients, each a recipe with different proportions, and are grouped into three experiments : critical point, binary alloy, and surface crystallization. [Text followed by an illustration of a BCAT-3 sample holder. ]

CONT

BCAT-3 is comprised of three separate experiments, which are individually referred to as a binary alloy(BCAT-3-BA), surface crystallization(BCAT-3-SC) and critical point(BCAT-3-CP). The critical point investigation is continuing with additional samples on future ISS [International Space Station] expeditions and will be referred to as Binary Colloidal Alloy Test-4. BCAT-4 will consist of two sets of samples referred to as BCAT-3 and 4 : Critical Point(BCAT-3-4-CP) and BCAT-4 : Polydisperse(BCAT-4-Poly).... The Binary Colloidal Alloy Test-3(BCAT-3) hardware supported three investigations in which ISS crews photographed samples of colloidal particles(tiny nanoscale spheres suspended in liquid) to document liquid/gas phase changes, growth of binary crystals, and the formation of colloidal crystals confined to a surface. Colloids are small enough that in a microgravity environment without sedimentation and convection, they behave much as atoms and so can be used to model all sorts of phenomena because their size, shape, and interactions can be controlled. The BCAT-3 payload consists of ten small samples of colloid alloys in which the microscopic colloid particles are mixed together into a liquid. These ten samples are contained within a small case that is the size of a school textbook. At the start of an experiment run, all ten samples are shaken to completely remix the colloid samples, much in the same way that salad dressing must be shaken to remix oil and vinegar. After the samples are mixed, what remains is periodically photographed using a digital camera until the colloid and liquid components of those samples have separated or the polymers have formed crystals. The samples can be remixed to repeat the experiment. The ten samples in BCAT-3 were selected as part of three separate experiments examining different physical processes : critical point, binary alloys, and surface crystallization.

Since its first flight on the Second International Microgravity Laboratory(IML-2) mission in July of 1994, the BDPU has been upgraded to accommodate a high-voltage power supply so that experiments on electrohydrodynamic processes can be performed. The facility can accommodate several types of test cells with each one dedicated to a specific experiment. Commands can be sent from the ground to inject bubbles into liquid-filled test cells and then to subject these cells to predetermined temperature differences. Cameras and sensors will observe and record temperatures and densities as well as the positions of bubbles or drops.

Mécaniques des fluides. Les expériences sont menées à l'aide d'un appareillage baptisé BDPU (Bubble, Drop and Particle Unit, soit «Unité Bulles, Gouttes et Particules») conçu et réalisé par l'ESA. Le processus étudié est le rôle de la tension engendrée à l'interface liquide/liquide, liquide/gaz. C'est cette tension qui donne par exemple à la bulle de savon sa forme sphérique caractéristique : plus la tension de surface de la bulle est forte et uniforme, plus la bulle est sphérique et stable. Cette tension à l'interface diminue quand la température augmente. Il s'ensuit que, dans un liquide, les bulles migrent vers la partie la plus chaude du liquide, ce phénomène porte le nom de migration thermocapillaire. Sur Terre, l'effet de cette tension interraciale est souvent masqué par la gravité. On a étudié entre autres comment les bulles et les gouttes réagissent dans un liquide soumis à des variations de température et de concentration, à la solidification ou l'évaporation.

CONT

The Clinostat has been used by biologists for over a hundred years to study how organisms might adapt to the microgravity environment and what effects the force of gravity has on plant and animal development and behavior. The clinostat is a simple device which places a plant, a small organism, or cell growing in culture on a rotating platform. The rotation causes the biosystem under test to be subjected to the gravity vector from "all" directions. From the system's point of view, the rotation cancels the gravity vector by continuous averaging thus approximating the highly reduced vector found in the actual space environment.

The Insect Habitat(IH) was designed to support a variety of insect species. However, during the initial flight increments, it will be dedicated to experiments using Drosophila melanogaster, or fruit flies. The Insect Habitat will enable studies of the fruit fly to learn how microgravity affects development, nervous system function, movement and behavior, growth, reproduction, aging, gene expression, mutagenesis from radiation and circadian rhythms or sleep/wake cycles.

CONT

The IH will support single-and multi-generation experiments that have approximate external dimensions of 13. 5 cm(L) x 2. 25 cm(D) x 7. 0 cm(H) each. The flies will live in two chevron-shaped container elements. These containers can be divided into two parts using the internal food cylinders; this yields two 55 ml containers that can support up to 100 Drosophila through to egg-laying. Alternatively, the containers can be left undivided, which yields a single 110 ml volume that supports up to 200 Drosophila.... The two insect containers reside in the science element portion of the IH. The science element consists of two environmentally controlled "drawers. "Each drawer contains a centrifuge that can provide up to 2G. Each centrifuge will hold six insect containers. Typically, one drawer will have a microgravity environment and the other drawer will have a defined gravity environment, although the precise gravity regimen for each centrifuge can be determined by the researcher.

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.

CONT

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.

Another very clever way-out was pioneered by the blind physicist Plateau already in the XIX century : the isodense tank(Plateau tank) with an immiscible liquid to balance the(high) hydrostatic gradient. But on both cases(millimetric-size liquid bridges and Plateau simulation) the mechanical behaviour(statics and dynamics) of liquid bridges is difficult to investigate under ground conditions because both techniques make experimentation difficult, imprecise and can mask effects only measurable under reduced gravity conditions. That explains why so many experiments with liquid bridges have been performed under microgravity since the pioneering demonstrations in Skylab in 1974, and how different the real behaviour of liquid bridges in space has been found.

Three Materials Science Research Racks will be a major portion of the U. S. Laboratory facilities. The European Space Agency will provide the core for the Experiment Module that will occupy the right half of the rack and will house five insert modules. NASA and ESA [European Space Agency] each will provide two inserts, and the German Space Agency(DLR) will provide a fifth. Each of the five inserts will be a furnace to process materials in different ways, such as melting and freezing a sample from one end to the other(directional solidification) or quenching a sample quickly to "freeze" its condition. The German insert will be a special furnace that uses a rotating magnetic field to control flows within the molten samples. The left half of the rack will be occupied for nine months by equipment from NASA's Space Products Development Division, before it is made available to microgravity science researchers. The Experiment Modules and their inserts will be replaceable in orbit, so an entire rack will not have to be returned to Earth. There will be a single experiment module in each rack with the experiment support systems taking the left half of the rack and an Experiment Module taking the right half of the rack.

The Material Science Laboratory (MSL) offers a multi-user capability to support scientific research in solidification physics, crystal growth with semi-conductors, measurement of thermophysical properties and the physics of liquid states. MSL occupies about half of an ISPR [International Standard Payload Rack] in the US Lab, and one ISPR in the Columbus Laboratory. The two MSL versions are identical except for minor rack interface differences. Each MSL comprises a core element consisting of a sealed process chamber in which interchangeable furnace inserts are hosted. These inserts process the samples. The sample cartridges are manually loaded into one of the furnaces. The furnace can be moved over the sample cartridge to displace the thermal gradients. Diagnostic systems provide scientific data on the facility and sample cartridge during operations. As the furnaces are modular, they can be upgraded or replaced according to utilisation needs. Additional MSL units complete the accommodation and operational interfaces to the laboratory.

CONT

The MSL will be developed in two versions : Facility 1, to be accommodated within the US Laboratory Module of the International Space Station; and Facility 2, to be accommodated on board the European Columbus Laboratory. These two facilities are very similar to each other; the main differences being that the US Laboratory version of MSL is accommodated inside the NASA Materials Science Research Rack. This rack is equipped with the Active Rack Isolation System ARIS, which provides a modicum of isolation from microgravity disturbances.

[...] le four TITUS [a été mis en marche] pour réaliser les expériences INSITU et EQUI. Ces deux expériences étudient, grâce à la micropesanteur, les phénomènes de solidification en l'absence de convection. La solidification d'un alliage métallique est en effet un phénomène complexe. Dans un «barreau» dont les extrémités sont maintenues à des températures hautes et basses encadrant la température du point de fusion, il s'établit un front de solidification. Selon les écarts de température (le gradient), ce front peut prendre différents aspects. Pour un faible gradient de température, le front de solidification demeure pratiquement plan. Dans ces conditions, en avant du front apparaissent, autour d'impuretés microscopiques, des grains de solidification à partir desquels la solidification s'effectue dans toutes les directions. Si le gradient augmente, le front se transforme et présente des petites excroissances solidifiées (des colonnes) qui donnent une croissance cristalline cellulaire (régulière). Si le gradient est encore plus important, ces colonnes se ramifient et donne une croissance cristalline dendritique (irrégulière). L'expérience INSITU étudie plus précisément la croissance cellulaire à l'aide d'un alliage cuivre-manganèse dont le point de fusion est de 870°C. L'expérience EQUI étudie la propagation de la solidification dans toutes les directions autour des noyaux de solidification (croissance «equiaxe») en utilisant un alliage aluminium-nickel dont la température de fusion est de 640°C.

Even in a gravity gradient attitude, accelerations caused by crew movements, equipment operations, and occasional thruster firings can disrupt the quiescent low-gravity environment and may affect microgravity science experiments. Accelerations at particular frequencies may interrupt one type of experiment but have no effect on others.
