A British science journal has named Russian scientist Viktor Grokhovskiy
as one of 10 people who made a difference in the world of science in 2013.
Nature magazine listed Grokhovskiy in its annual "Nature's 10" for his
research on meteorite that exploded over Chelyabinsk on February 15.

Grokhovskiy, a professor at the Urals Federal University and a member
of the Russian Academy of Sciences Committee for Meteorites, said the
recognition came as a welcomed surprise.

"It's like a Nobel Prize for us, although you don't actually win a prize.
But it is very nice; we are very happy," he said. "At the end of the day
though it is not only me who deserves the credit, a great number of people,
my colleagues, contributed to these achievements."

Grokhovskiy said he received hints that something was going on about two
weeks ago, when he began to receive phone calls from the journal asking
for a photo but without giving a reason, he said.

The meteorite, which came down in the Chelyabinsk region, approached the
planet from a direction that is invisible to telescopes on Earth and took
astronomers by surprise. Two days later, Grokhovskiy had efficiently calculated
the trajectory of the meteorite and where the fragments would have landed.
He then led an exhibition to collect more than 700 fragments of this celestial

Students, postgraduate students and lecturers from the 'Nanotech' Nauchno-Issledovatelskiy
Tsentr (Scientific Research Centre) had already discovered the first fragments
by February 17.

Scientists installed a web camera overnight and showed the whole world
debris from the meteorite on February 18. It was then that they established
the type of matter and calculated the final trajectory of this "guest
from outer space" to define where the main part would have come down.

On the basis of these calculations Grokhovskiy's expedition led scientists
to Lake Chebarukl, from where smaller fragments weighing 5.5 kilograms
as well as a large fragment weighing 570 kilograms were removed. When
the biggest fragment was raised from the bottom of the lake on October
17, Viktor Grokhovskiy said he was still unable to get over the size.

"Less matter was brought back from the Moon than we discovered in one
lake!" he said.

Studies into this alien from outer space are still ongoing.

"We are now checking to see if any of our hypothesis can be confirmed.
I cannot say which hypothesis as it's an academic secret. If I were to
tell you now, other scientists could take up the theses, competition in
the scientific world is very fierce," Grokhovskiy said.
