Georgy V. Kurdjumov (Георгий Вячеславович Курдюмов) was a Soviet physicist and metallurgist, born in 1902, who discovered the diffusionless martensitic transformation in steels and directed major Soviet research institutes in Moscow and Chernogolovka.

Georgy Voronoy

Georgy Voronoy (1868–1908) was a mathematician of the Russian Empire, born in Ukraine, who created Voronoi diagrams and co-founded the geometry of numbers with Hermann Minkowski.

Georgy Zhukov (Георгий Константинович Жуков)

Georgy Konstantinovich Zhukov (Георгий Константинович Жуков, 1896–1974), Marshal of the Soviet Union and four-time Hero, led Leningrad's defense, Moscow, Kursk coordination, Operation Bagration, and Berlin, and accepted Germany's 1945 surrender.

GEOS-Chem

GEOS-Chem is a global 3-D model of atmospheric chemistry that simulates atmospheric composition from local to global scales using NASA GEOS meteorological data, widely used in air quality and climate research.

Geosat

Geosat was a United States Navy satellite launched in 1985 carrying a radar altimeter that measured sea surface height to about 5 cm precision, becoming a milestone oceanography data set.

Geoscience Australia

Geoscience Australia is the Australian Government's national geoscience research and geospatial information agency, created in 2001 by merging AGSO and AUSLIG to support resource exploration, environmental management, and community safety.

Geosiphon

Geosiphon (Geosiphon pyriformis, synonym G. pyriforme) is a rare glomeromycotan soil fungus in Archaeosporales that uniquely hosts the cyanobacterium Nostoc punctiforme inside bladder-like vesicles instead of forming arbuscular mycorrhiza with plants.

Geosmin

Geosmin is an organic compound, produced mainly by Streptomyces bacteria, that gives moist soil its characteristic earthy smell and causes earthy taste complaints in drinking water.

Geosmin synthase

Geosmin synthase (SCO6073, geoA) is a bifunctional bacterial terpene cyclase from Streptomyces coelicolor that converts farnesyl diphosphate to germacradienol, then to geosmin and acetone, using only Mg2+; the cause of earthy soil and water odors.

Geospiza

Geospiza, the ground finches of the Galápagos established by John Gould in 1837, is a genus of Darwin's finches in Thraupidae, with six traditionally recognized species whose beak evolution is driven by seed diet, the ALX1 locus, and hybridization.

GEOStar

GEOStar is a family of geostationary commercial communications satellite buses developed by Orbital Sciences Corporation and now produced by Northrop Grumman, with more than 50 satellite contracts.

Geostationary Ocean Color Imager

The Geostationary Ocean Color Imager (GOCI) is a South Korean ocean color imaging radiometer on the COMS satellite and the world's first geostationary ocean color sensor, launched in 2010.

Geostationary orbit

A geostationary orbit, also called the Clarke Belt or Clarke orbit, is a circular equatorial orbit at 35,786 km where a satellite stays fixed above one spot on Earth.

Geostationary slot

A geostationary slot is a longitude position on the geostationary arc, about 35,786 km above the equator, that operators hold through the International Telecommunication Union together with assigned frequencies.

Geostationary transfer orbit

The geostationary transfer orbit, also known as the geosynchronous transfer orbit or GTO, is a highly elliptical parking orbit with perigee near low Earth orbit and apogee at geostationary altitude.

Geostatistical inversion

Geostatistical inversion is a stochastic seismic inversion method, introduced in 1993, that generates multiple equiprobable property models conditioned to seismic data and well logs, quantifying uncertainty.

Geosteering

Geosteering, also called real-time well placement, is a drilling technique that uses real-time geological data to keep the wellbore within the target reservoir, mainly in horizontal wells.

Geostorm

Geostorm is a 2017 American science fiction disaster film about satellites that control the weather, directed by Dean Devlin and starring Gerard Butler, Ed Harris, and Andy Garcia.

Geostrophic current

A geostrophic current is an ocean current in which the Coriolis force from Earth's rotation balances the horizontal pressure gradient force, so the water flows along lines of constant pressure.

Geostrophic flow

Geostrophic flow is air or water motion in which the pressure-gradient force and Coriolis force balance, so flow moves parallel to isobars rather than across them.

Geosynchronous orbit

A geosynchronous orbit (GEO) is an Earth orbit with a period of one sidereal day, at about 35,786 km altitude, so satellites stay over a fixed longitude.

Geosynchronous satellite

A geosynchronous satellite is an artificial satellite whose orbital period matches Earth's rotation, circling at about 35,900 km above the surface; a circular equatorial one appears motionless.

Geosynchronous Satellite Launch Vehicle

The Geosynchronous Satellite Launch Vehicle (GSLV) is a three-stage expendable rocket developed by India's ISRO, first flown in 2001 to place communication satellites into geostationary transfer orbit.

Geosynchronous transfer using electric propulsion

Geosynchronous transfer using electric propulsion is the technique of raising a communications satellite to geostationary orbit with low-thrust electric thrusters over months, saving about 40% launch mass.
