NASA claim that the planet is so responsive to the sun spots.
NASA presents report on the state of the near-Earth space. In terms of its trash. Nick Johnson (Nick Johnson), a representative of the agency in charge of the problem, according to information released by letter that "in 2011 the number of registered space debris orbiting the Earth was considerably reduced."
Nick sure that the space cleared by the fact that inflated atmosphere. It ballooned from that increased the amount of UV radiation coming from the sun. And it has increased because the light more and more abundant stained, spewing more coronal mass ejections.
The nature of the cleaning effect is simple: the bloated atmosphere "get" to the affected satellite located high up their debris. The so-called re-entry starting located further from the Earth, brake dust, which falls lower and lower until it burns up. Or falls.
According to Johnson, a 2011 space debris was 6 percent lower. Half of it fell to Earth at the end of the year, when, in fact, began to swell atmosphere.
The wreckage of the Russian device "Cosmos 2251? and American "Iridium 33?, which clashed in 2009, are still in orbit. But they sink lower and lower. And is projected to fall out meteors in 2012-2013.
And the "Phobos-Grunt" is already down, spending debris only about 2 months.
By the way, from the bloated atmosphere and the atmospheric pressure increases, the values of which are abnormally high — above 760 mm Hg — recently become the norm.
