Asteroid mining is the hypothetical extraction of materials from asteroids and other minor planets, including near-Earth objects. [1] Notable asteroid mining challenges include the high cost of spaceflight, unreliable identification of asteroids which are suitable for mining, and the challenges of extracting usable material in a space environment.

Meteor burst communications ( MBC ), also referred to as meteor scatter communications, [1] is a radio propagation mode that exploits the ionized trails of meteors during atmospheric entry to establish brief communications paths between radio stations up to 2,250 kilometres (1,400 mi) apart. There can be forward-scatter or back-scatter of the ...
Meteorite. The 60- tonne, 2.7 m-long (8.9 ft) Hoba meteorite in Namibia is the largest known intact meteorite. [1] A meteorite is a rock that originated in outer space and has fallen to the surface of a planet or moon.

Meteorite classification. In meteoritics, a meteorite classification system attempts to group similar meteorites and allows scientists to communicate with a standardized terminology when discussing them. Meteorites are classified according to a variety of characteristics, especially mineralogical, petrological, chemical, and isotopic properties.
The LL chondrites are a group of stony meteorites, the least abundant group of the ordinary chondrites, accounting for about 10–11% of observed ordinary-chondrite falls and 8–9% of all meteorite falls (see meteorite fall statistics ). The ordinary chondrites are thought to have originated from three parent asteroids, with the fragments ...
