NASA "fired satellites see all over the earth
Launched the U.S.
space agency "NASA,"
a satellite dedicated for
the purposes of
climate change and
weather conditions and
weather, according to
a statement issued by
the U.S. Agency.
The agency noted in its
statement that the
satellite, and the
weight of two tones, is
designed to orbit at an
altitude of 512 miles
from the earth, they will
be able to see all over
the earth. The agency
said the satellite,
known as "NPOESS",
launched on Friday
morning, according to
local time, from
Vandenberg Air Force
Base in California.
The "NASA" was launched, earlier, a satellite to perform a task that will last for three years, aims to provide a better
understanding of climate change witnessed by the planet, in addition to scanning the seas and oceans to try to monitor any
change in the salinity of its waters.
She explained, "NASA" that the moon is named after a month will provide detailed maps showing rates of salinity of the water
and the movement of ocean currents, and other sensitive information to help understand the environmental challenges facing
USAID expects to have the information provided by satellite a crucial role in helping scientists to predict phenomena such as
"El Nino" and "La Nina", which is reflected annually in the form of a devastating tropical storms in the Pacific, according to the
The "NASA" that the process of launching the moon that comes in the context of a project that began in 2001 represents a
quantum leap forward, especially as the research on the salinity of the sea and weather events similar survey was limited to
the field through the vessels and floating laboratory.
Previously shown, although a study by a team of climate experts that one of the planets orbiting the dwarf star known as the
"Gliese 581" may be "uninhabitable" with a favorable climate allows the availability of liquid water and the life.
Astronomers and seeks to find out whether some of the more than 500 of the planet outside the solar system detected so far,
there are the conditions that allow the establishment of life on them.
And announced the National Center for Scientific Research "CNN RSS in France" in a statement that the planet "Gliese 581
D", which has a mass more than seven times the mass of the earth which is probably a natural rock "has become the first
planet discovered so far capable to receive the form of of life. "
And monitoring of the planet in 2007, 20 light-years (equivalent to light-year 9500 billion kilometers) from the solar system.
He said, "Gliese 581 D" at the beginning of many cold, consequently, can not be considered "viable qualifies as" any other
words that have the temperature would permit liquid water on its surface.
This is one of the planet outside the solar system revolves around the hotter star is a red dwarf star, receives three times less
energy than those received by the earth from the sun. This seems to always appear on the shuttle and one off the other side
Ndjemth Vngriq always in darkness.
Despite these obstacles, it may be the planet "Gliese 581 D" benefit from the greenhouse effect, which provided him with a
climate "warm enough to allow the rise of the oceans and clouds and rain," as shown simulation on the computer, referred to
"the great diversity of climates possible planets galaxy" is explained French National Center for Scientific Research.
Thanks to a phenomenon known as "Riley", which gives the blue sky on the ground, reflecting the atmosphere of the planet
in space, a large part of the blue beam, which limits the high temperature of our planet. This effect is not the Chief with the
color red on say the researchers, who published their work in the scientific journal "The Astrophysical Journal Letters."
It may be the planet "Gliese 581 D" is the third planet orbiting the red dwarf star lying in the light of a light red color tends to
be thick with atmosphere and a layer of clouds
