eceived by users anywhere on Earth <strong>to</strong> identify their position<br />

and velocity in real time based on ranging measurements.<br />

<strong>The</strong> first GLONASS satellites were placed in orbit<br />

in 1982. Each satellite is identified by its “slot” number,<br />

which defines the orbital plane (1–8, 9–16, 17–24) and the<br />

location within the plane. <strong>The</strong> three orbital planes are separated<br />

by 120°, and the satellites within the same orbital<br />

plane by 45°. <strong>The</strong> GLONASS orbits are roughly circular,<br />

with an inclination <strong>of</strong> about 64.8° and a semimajor axis <strong>of</strong><br />

25,440 km. <strong>The</strong> full constellation is supposed <strong>to</strong> contain<br />

24 satellites, arranged in three orbital planes; however,<br />

Russia’s economic troubles prevented replacement satellites<br />

from being launched as needed. As <strong>of</strong> mid-2002, only<br />

9 GLONASS satellites were operational.<br />

Glushko, Valentin Petrovitch (1908–1989)<br />

A Soviet rocket scientist, a pioneer in rocket propulsion<br />

systems, and a major contribu<strong>to</strong>r <strong>to</strong> Soviet space and<br />

defense technology. He was born in Odessa, Ukraine.<br />

After graduating from Leningrad State University (1929),<br />

Glushko headed the design bureau <strong>of</strong> the Gas Dynamics<br />

Labora<strong>to</strong>ry in Leningrad and began research on electrothermal,<br />

solid-fuel, and liquid-fuel rocket engines. In<br />

1935, he published Rockets, <strong>The</strong>ir Construction and Utilization.<br />

<strong>From</strong> 1932 <strong>to</strong> 1966, Glushko worked closely with<br />

renowned rocket designer Sergei Korolev. <strong>The</strong> two<br />

achieved their greatest triumphs in 1957 with the launching<br />

<strong>of</strong> the first intercontinental ballistic missile in August<br />

and the first successful artificial satellite, Sputnik 1, in<br />

Oc<strong>to</strong>ber. In 1974 Glushko was named chief designer <strong>of</strong><br />

the Soviet space program, in which he oversaw the<br />

development <strong>of</strong> the Mir space station. He received<br />

numerous <strong>of</strong>ficial honors, including the Lenin Prize<br />

(1957) and election <strong>to</strong> the Soviet Academy <strong>of</strong> Sciences<br />

(1958).<br />

GMS (Geostationary Meteorological Satellite)<br />

A series <strong>of</strong> weather satellites managed by the Japanese<br />

Meteorological Agency and NASDA (National Space<br />

Development Agency); their indigenous name, Himawari,<br />

means “sunflower.” All have been located in geostationary<br />

orbit at 140° E. <strong>The</strong> first GMS was launched in<br />

1977 and the most recent, GMS-5, on March 18, 1995.<br />

GMS-5 is equipped with a VISSR (Visible and Infrared<br />

Spin Scan Radiometer), which scans Earth’s surface line<br />

by line, each line consisting <strong>of</strong> a series <strong>of</strong> pixels. For each<br />

pixel the radiometer measures the radiative energy at<br />

three different wavelength bands—one in the visible<br />

region and two in the infrared.<br />

GMT (Greenwich Mean Time)<br />

A worldwide time standard; the time as measured on the<br />

Greenwich meridian. Also known as Universal Time.<br />

GOES (Geostationary Operational Environmental Satellite) 165<br />

go, no-go<br />

A term used <strong>to</strong> indicate a condition <strong>of</strong> a part, component,<br />

system, and so forth, which can have only two<br />

states. “Go” indicates “functioning properly”; “no-go”<br />

means “not functioning properly.”<br />

Goddard Institute for Space Studies<br />

An arm <strong>of</strong> NASA’s Goddard Space Flight Center that<br />

conducts theoretical and experimental research in global<br />

change. It is located next <strong>to</strong> Columbia University’s Morningside<br />

Campus in New York City. Work at the Institute<br />

focuses on humanity’s large-scale impact on the environment<br />

and fosters interaction among scientists in atmospheric,<br />

geological, and biological sciences. It includes<br />

long-range climate modeling, and analysis <strong>of</strong> biogeochemical<br />

cycles, Earth observations, and planetary atmospheres.<br />

Goddard, Robert Hutchings<br />

See article, pages 166–167.<br />

Goddard Space Flight Center (GSFC)<br />

NASA’s foremost field center for programs related <strong>to</strong><br />

space science and observation from space <strong>of</strong> the Earth<br />

and its environment. Founded in 1959, it was named<br />

after the rocket pioneer Robert Goddard and is located in<br />

Greenbelt, Maryland, 16 km northeast <strong>of</strong> Washing<strong>to</strong>n,<br />

D.C. Goddard Space Flight Center has designed, built,<br />

and operated numerous near-Earth orbiting spacecraft,<br />

including members <strong>of</strong> the Explorer series, and controls<br />

several astronomy satellites, including the Hubble Space<br />

Telescope. It manages the National Space Science Data<br />

Center and is responsible for the Wallops Flight Facility.<br />

Godwin, Francis (1562–1633)<br />

Bishop <strong>of</strong> Hereford and author <strong>of</strong> what is arguably the<br />

first science fiction s<strong>to</strong>ry <strong>to</strong> be written in the English language.<br />

In <strong>The</strong> Man in the Moone, 131 published posthumously<br />

in 1638, Godwin conveys the astronaut<br />

Domingo Gonsales <strong>to</strong> the Moon in a chariot <strong>to</strong>wed by<br />

trained geese. (Gonsales had intended a less ambitious<br />

flight but discovered that the geese are in the habit <strong>of</strong><br />

migrating a little further than ornithologists had supposed!)<br />

In keeping with both popular and scientific opinion<br />

<strong>of</strong> his day, Godwin accepted the notion that air filled<br />

the space between worlds and that the Moon was inhabited<br />

by intelligent human beings. See Wilkins, John and<br />

Cyrano de Bergerac, Savinien de.<br />

GOES (Geostationary Operational<br />

Environmental Satellite)<br />

A series <strong>of</strong> weather satellites that superseded the SMS<br />

(Synchronous Meteorological Satellite) program and,<br />
