August 3, 2004 was
launched interplanetary station "Messenger". Its aim was to study the
closest planet to the Sun, Mercury. The unit flew to the hot planet 7 years,
and only in 2011 it entered the orbit. For two years in orbit, he was able to
do a lot of images of Mercury's surface, collected and handed over a huge
amount of information on the Earth. Powerful Space probe "Messenger"
is equipped with a dual-mode camera, spectrometers, four species, altimeter,
and a magnetometer.
It was officially
announced that his mission will last until March 17, 2012. But then, on the
basis of his research, NASA extended the mission he had planned for a year. And
after that time, NASA decided on the operation of the machine in normal mode
until such time as not run out of fuel. As a result of its expanded mission,
"Messenger" has managed to examine 100% of the surface of the planet.
And another decision was made to extend the mission to orbit Mercury for one
more year. Space probe will stay there until April 2014.
Today we offer review
the most interesting research results, "Messenger".
On the hottest planet
in the solar system has been found water, however, in the solid state. Ice is
on the north pole of Mercury. The possibility of finding water on the planet
expressed in the 70-ies according to the radio "Arecibo", and that
interplanetary station "Messenger" is confirmed. Scientists have not
yet figured out the nature of the appearance of ice on the surface of the
planet. Nominate in two versions: it is in the area, which had no sunlight, and
therefore preserved, and he was there with asteroids and comets. At the moment,
the issue is being studied.
Photos of Mercury made
by the machine, basically, show craters and other signs of violent tectonic
activity on the planet. All craters on Mercury scientists call the names of
prominent artists.
Sometimes scientists
see in the pictures with the "Messenger" silhouettes and outlines of
those famous characters. For example, in this picture there are three images of
Mickey Mouse. It was also found images of smiling faces. By the way, smiley
previously found on other planets, but this one - with Mercury.
Analysis of the
magnetosphere of Mercury led to the conclusion of the direct relationship
between magnetic fields and the solar wind (a stream of ionized particles
flowing from the sun's corona).
The neural detector
interplanetary probed has analyzed solar flares and concluded that the presence
of high-energy neutrons. These neutrons cannot occur on the territory of the
Earth because of the short duration of the life of our planet.
During their flight,
"Messenger" was able to make a "family portrait" of the
planets of the solar system, thus complementing already existing knowledge
about their location.
