The local orbital reference system is defined at each point of the orbit by three unit vectors. These vectors are derived from the satellite position and velocity vectors: Vector L is colinear with position vector P (on the axis between the Earth’s centre and the satellite). It defines the yaw axis. Vector T is perpendicular to the orbital plane (vector L, vector V). It defines the pitch axis. Vector R completes the set of orthogonal axes. It lies in the plane defined by Vectors L and V and defines the roll axis. It does not coincide exactly with the velocity vector due to the eccentricity of the orbit.

CONT

Spacecraft axes. The three orthogonal axes of rotation : roll, pitch and yaw. If the spacecraft has a recognisable longitudinal axis or a specified forward direction of flight, the axes are analogous to those of an aircraft, where the roll axis is the longitudinal axis; the pitch axis is in the plane of the wings; and the yaw axis is the "vertical" axis, orthogonal to both the roll and pitch axes. The axes are mutually perpendicular, with an "origin" at the vehicle's centre of mass. For a winged spacecraft such as a Space Shuttle, the similarity with an aircraft is obvious. For expendable launch vehicles the roll axis is the axis which is vertical at launch and the other axes are more-or-less arbitrarily assigned since the vehicle rotates about the roll axis in flight.... The axes of a cylindrical spacecraft(e. g. Apollo, Suyuz, etc.) are similar to those of an ELV [Expendable Launch Vehicle] at launch, but one orbit assume the axis-definition of an aircraft(i. e. defined relative to the pilot's seat). The axes of a satellite mirror those of an aircraft "flying along the orbital arc" : the roll axis is aligned with the direction of travel; the yaw axis passes through the sub-satellite point; and the pitch axis is orthogonal to the other two. For a satellite in an equatorial orbit, the pitch axis is aligned approximately with the Earth's spin axis. The pitch axis is also the spin axis for the spin-stabilised satellite.

OBS

In the compilation of engineering drawings the three orthogonal axes are often labelled in Cartesian fashion: x=roll, y=pitch, z=yaw. For the three-axis stabilised spacecraft, the x-axis and y-axis are otherwise known as the east-west and north-south axes, respectively; the z-axis passes through the sub-satellite point. This leads to the definition of the box-shaped satellite’s faces as follows: the "plus-x face" faces east; the "minus-x face" faces west; +y faces south; -y faces north; +z is the Earth-pointing face; and -z is the "anti-Earth face."

OBS

For the purpose of this discussion, "weaponization" is limited to destructive mechanisms and do not include observation, communications or other non-destructive activities, even if military in nature. The weaponization of space could take a variety of forms. First, there is the threat from above posed by space strike or orbital bombardment weapon systems. Orbital bombardment weapons are weapon systems that operate in space for one or more orbits and strike at land, sea or air targets. Secondly, there are anti-satellite(ASAT) weapon systems used to permanently degrade, damage or destroy enemy satellites. Lastly, there are ballistic missile defence(BMD) weapon systems. Some variants of BMD systems may be based in outer space and be used to destroy incoming ballistic missiles through the boost and mid-course phases of their flight. Putative weapons, such as orbiting space-based lasers based on "exotic" technologies or variants of conventionally-armed and kinetic energy "kill-mechanism" missile interceptors may be capable of performing all three functions.

OBS

[...] l'«arsenalisation» se limite aux mécanismes destructeurs et ne comprend pas les activités d'observation, de communication et d'autres activités non destructrices, même si elles sont de caractère militaire. L'arsenalisation de l'espace pourrait prendre diverses formes. Se pose premièrement la menace venant des systèmes d'armement de frappe spatiale ou de bombardement orbital. Les armes de bombardement orbital sont des systèmes d'armes qui opèrent dans l'espace pendant une orbite ou davantage et frappent des cibles terrestres, maritimes ou aériennes. Deuxièmement, il existe des systèmes d'arme antisatellite (ASAT) servant à dégrader, endommager ou détruire en permanence des satellites ennemis. Enfin, il existe des systèmes d'arme de défense antimissiles balistiques (ABM). On peut déployer certaines variantes de systèmes ABM dans l'espace extra-atmosphérique et les utiliser pour détruire des missiles balistiques en approche pendant les phases de propulsion et à mi-parcours de leur vol. Des armes présumées, comme des lasers en orbite basés dans l'espace et reposant sur des technologies «exotiques» ou des variantes des intercepteurs de missiles armés de charges conventionnelles et d'énergie cinétique à «mécanisme de destruction» peuvent être capables de remplir ces trois fonctions.

At NLR [National Aerospace Laboratory], the motion of a partially filled tank is studied for its relevance to the control of manoeuvring space vehicles with liquid stores.... An experimental programme with investigations on parabolic flight, in suborbital and orbital trajectories, has been defined and is in preparation. The present immediate objective is the synthesis of the so-called Wet Satellite Model experiment which includes the development of a diagnostic instrument("ballistometer") and the launch of a test article in a seven-minute parabola by sounding rocket.

The complementary nature of the LMS [Life and Microgravity Spacelab] musculoskeletal experiments has engendered the development of a multi-purpose workstation to support each of the investigations : the Torque Velocity Dynamometer, or TVD. Developed by the European Space Agency specifically in response to the science requirements of this mission, the TVD is the platform for many of the in-flight musculoskeletal activities, as well as for those that establish baseline measurements before the flight and provide follow-on data after the orbital segment of the mission.

H-II Transfer Vehicle is one of the orbital transfer vehicles which is designed to transport various cargos to the International Space Station(ISS) with the Japanese H-IIA rocket. The HTV will approach and hover beside the Space Station, then the HTV will be captured by ISS manipulator and will be berthed to the predicted position. To avoid any hazardous situation to the Space Station during free flight, the HTV is designed to meet the needs of high reliability and safety. The HTV is planned to outfit with two types of logistics carrier for efficient transportation.

The description of the Station's flight attitude(orientation relative to the plane of its orbit) is referenced to local-vertical/local-horizontal(LVLH) axes that are fixed with respect to the Station's near-circular orbit(i. e., not to the physical Station). The LVLH origin is at the Station's center-of-mass; the z-axis points radially toward the Earth's center(or toward the nadir direction), the x-axis points along the orbital velocity vector(the ram direction, with wake being opposite), and the y-axis completes the right-handed triad. The flight attitude of the Station is then described using a second, Station-fixed, coordinate system whose orientation relative to LVLH is specified using the Eulerian angles of yaw, pitch and roll. Several Station-fixed coordination systems are defined. The most widely used is the Space Station Reference Coordinate System,... in thich the positive x-axis points along the axis of the U. S. lab away from the Zarya and Service Modules; the positive y-axis points starboard along the main truss, and positive z completes a right-handed coordinate system.
