  2. Magnetosphere - Wikipedia

    en.wikipedia.org/wiki/Magnetosphere

    Mercury, Earth, Jupiter, Ganymede, Saturn, Uranus, and Neptune, for example, exhibit intrinsic magnetospheres. A magnetosphere is classified as "induced" when , or when the solar wind is not opposed by the object's magnetic field. In this case, the solar wind interacts with the atmosphere or ionosphere of the planet (or surface of the planet ...

    en.wikipedia.org/wiki/Khowar_alphabet

    Since the early twentieth century Khowar has been written in the Khowar alphabet, which is based on the Urdu alphabet and uses the Nasta'liq script. Prior to that, the language was carried on through oral tradition. Today Urdu and English are the official languages and the only major literary usage of Khowar is in both poetry and prose composition.

    The mission comprises two satellites launched together: the Mercury Planetary Orbiter (MPO) and Mio (Mercury Magnetospheric Orbiter, MMO). [5] The mission will perform a comprehensive study of Mercury, including characterization of its magnetic field , magnetosphere , and both interior and surface structure.

    Schematic of the Birkeland or Field-Aligned Currents and the ionospheric current systems they connect to, Pedersen and Hall currents. [1]A Birkeland current (also known as field-aligned current, FAC) is a set of electrical currents that flow along geomagnetic field lines connecting the Earth's magnetosphere to the Earth's high latitude ionosphere.

    A substorm, sometimes referred to as a magnetospheric substorm or an auroral substorm, is a brief disturbance in the Earth's magnetosphere that causes energy to be released from the "tail" of the magnetosphere and injected into the high latitude ionosphere.

  8. Magnetic sail - Wikipedia

    en.wikipedia.org/wiki/Magnetic_sail

    Magnetic sail animation. A magnetic sail is a proposed method of spacecraft propulsion where an onboard magnetic field source interacts with a plasma wind (e.g., the solar wind) to form an artificial magnetosphere (similar to Earth's magnetosphere) that acts as a sail, transferring force from the wind to the spacecraft requiring little to no propellant as detailed for each proposed magnetic ...

    The ray can be formed by any wave: optical, acoustic, microwave, X-ray, etc. angle of reflection The change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound, and water waves.
