The first spacecraft to make it to the Moon was the Luna 2. The Luna 2 was made by the Soviet Union, and it reached the Moon in 1959. The Luna 2 took a direct path to the Moon, and the journey took approximately 34 hours. The shortest trip to the Moon was undertaken in 2006 by NASA, by the probe New Horizons.
ferrous metallurgy definition, ferrous metallurgy meaning | English dictionary. ferrous. n an iron salt with a saline taste, usually obtained as greenish crystals of the heptahydrate, which are converted to the white monohydrate above 100Â°C: used in inks, tanning, water purification, and in the treatment of anaemia. Formula: FeSO4, (Systematic name) iron(II) sulphate (Also called) copperas, green vitriol.
Generally more expensive than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight (e.g. aluminium), higher conductivity (e.g. copper), non-magnetic property or resistance to corrosion (e.g. zinc). Some non-ferrous materials are also used in the iron and steel industries. For example, bauxite is used as flux for blast furnaces, while others such as wolframite, pyrolusite and chromite are used in making ferrous alloys.
