The United States “Stardust” was the first probe to obtain samples of cosmic dust
[REVIEW] America’s “Stardust” was the first time in human history, probe to obtain the diffuse interstellar cosmic dust in the samples and returned them to Earth.
Tencent Technology News (compiler / Fan Yao) Beijing March 8, according to Russian news network reported that the U.S. “Stardust” was the first time in human history, probe to obtain a diffuse in the interstellar dust samples and of the universe They returned to Earth. Scientists said it was the first human to receive such material. According to reports, the dust is to build a variety of visible objects in the universe – including the stars and planets – the main material.
Cosmic dust in the visible part of the universe constitute the basis of the material
“Stardust” was the original mandate probe is set to obtain “wild 2″ samples of comet tail material and its back to Earth for analysis.
However, NASA experts were also given another task of the detector – to capture interstellar dust.
In the seven years of flight, the “Stardust” spacecraft has been over 4.8 billion kilometers. On which the container is equipped with a special place are aerosols, to collect the diffuse small matter in the universe.
In January 2006, the detector will have to collect comet material and containers are fired back to Earth.
In the container through the material collected for analysis, scientists are surprised to find that there are still two of them actually interstellar dust. According to reports, one from an interstellar dust found in Canada’s Bruce Hudson. Bruce Hudson is currently working with thousands of other researchers in “Stardust” spacecraft returned to local material for analysis.
Currently, Hudson discovered that interstellar dust has been named “Orion.”
According to reports, the main interstellar dust debris ejected from the stars made of gas evolution. This dust can stably exist in the space among withstand cosmic rays and gravitational field role. It is these tiny substances finally get together and evolved into a celestial body such as the solar system construction.
At present, scientists have discovered two new kinds of cosmic dust samples to detect magnesium, aluminum, iron, chromium, nickel, manganese, copper and calcium metal.
