Electron magnetic moment. In atomic physics, the electron magnetic moment, or more specifically the electron magnetic dipole moment, is the magnetic moment of an electron resulting from its intrinsic properties of spin and electric charge. The value of the electron magnetic moment (symbol μe) is −9.284 764 7043(28) × 10−24 J⋅T−1. [1]
Magnetochemistry is concerned with the magnetic properties of chemical compounds. Magnetic properties arise from the spin and orbital angular momentum of the electrons contained in a compound. Compounds are diamagnetic when they contain no unpaired electrons. Molecular compounds that contain one or more unpaired electrons are paramagnetic.
Parking orbit. A parking orbit is a temporary orbit used during the launch of a spacecraft. A launch vehicle boosts into the parking orbit, then coasts for a while, then fires again to enter the final desired trajectory. The alternative to a parking orbit is direct injection, where the rocket fires continuously (except during staging) until its ...
A momentum exchange tether is a kind of space tether that could theoretically be used as a launch system, or to change spacecraft orbits. Momentum exchange tethers create a controlled force on the end-masses of the system due to the pseudo-force known as centrifugal force. While the tether system rotates, the objects on either end of the tether ...
Operation Barbarossa (German: Unternehmen Barbarossa; Russian: Операция Барбаросса, romanized: Operatsiya Barbarossa) was the invasion of the Soviet Union by Nazi Germany and many of its Axis allies, starting on Sunday, 22 June 1941, during the Second World War. It was the largest and costliest land offensive in human history ...

Barbados. / 13.167°N 59.550°W / 13.167; -59.550. Barbados is a continental island in the North Atlantic Ocean and is located at 13°10' north of the equator, and 59°32' west of the Prime Meridian. As the easternmost isle of the Lesser Antilles in the West Indies, Barbados lies 160 kilometres (100 mi) east of the Windward Islands and ...
Mercury-Atlas 5 was an American spaceflight of the Mercury program. It was launched on November 29, 1961, with Enos, a chimpanzee, aboard. The craft orbited the Earth twice and splashed down about 200 miles (320 km) south of Bermuda, and Enos became the first primate from the United States and the third great ape to orbit the Earth.
