The Pagan holiday called Yule takes place on the day of the winter solstice, around December 21 in the northern hemisphere(below the equator, the winter solstice falls around June 21). On that day, [the] earth's axis tilts away from the sun in the Northern Hemisphere, and the sun reaches its greatest distance from the equatorial plane.... As a festival of the Sun, the most important part of any Yule celebration is light — candles, bonfires, and more. 2, record 4, English, - Yule

Cette date proche de Noël est souvent associée à cette fête. On se rassemble, on mange, on boit et on festoie en l'honneur de la renaissance du Dieu soleil.

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.

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. 4, record 11, English, - roll%20axis

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." 4, record 11, English, - roll%20axis

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." 3, record 12, English, - pitch%20axis

Le repère orbital local est défini en chaque point de l'orbite par les trois vecteurs unitaires. Ces vecteurs sont construits à partir du vecteur position et du vecteur vitesse du satellite : Le vecteur L est colinéaire au vecteur position P (sur l'axe centre Terre, satellite). Il définit l'axe de lacet. Le vecteur T est perpendiculaire au plan de l'orbite (vecteur L, vecteur V). Il définit l'axe de tangage. Le vecteur R complète le trièdre.

For the Earth, the plasmapause is described as the equipotential boundary between a region dominated by the corotational electric field, where there are closed particle orbits, and a region dominated by a convective dawn-dusk electric field, where there are no closed orbits. However, the existence of such a static boundary for the dynamic magnetospheres of Uranus and Neptune has been called into question, by two dimensional guiding center calculations for particles in the magnetic equatorial plane. 3, record 16, English, - plasmapause
