Jakarta - Increased activity of the Sun in the year 2012 not only predicted the future cause sun flares or explosions. Space trash floating in the sky could fall to earth.
"By 2012 and 2013 the amount of waste expected to fall more and more," said
Head Utilization Center for Atmospheric and Climate Science, Institute of Aviation and Space Agency (Lapan) Thomas Djamaludin when discussing with the media at the Office Lapan Bandung, Jl Djundjunan, Bandung, Java West, Thursday (10/12/2009) yesterday.
Thomas explained, the increased activity of the Sun affect the density of the atmosphere. Increasing the maximum activity of the sun, the atmosphere here on this earth will thicken. Then, increase the thickness of the atmosphere will cause the garbage in space is easy to fall.
Thomas pointed out, when the storm the sun in 2003 and then, almost every week there's space junk that moves down. Three years earlier, when the Sun reaches the peak activity cycle to 23, almost every day there's space junk that fell in certain areas on Earth.
"Right now there are more than 13 thousand waste of space whose size is more than 1 cm," said one professor at the Institut Teknologi Bandung (ITB) is.
According to Thomas, the garbage comes from space debris and satellite spacecraft. Trash with altitude below 600 km the main concern. When you are down at the height of 150 km, the garbage in a matter of hours against the surface of the earth.
But reserve your fears about falling space junk. According to Thomas, the possibility (probability) of garbage is about the objects owned by a very small man. Most areas of the earth is ocean, desert, and uninhabited forest.
"Areas that inhabited the Earth a little. The possibility that crap about the objects of the building, vehicle or person to person it would be smaller," said Thomas.
However, Thomas added, caution still needs to be built. Rubbish space has "fall line" which can be monitored separately. For example garbage that fell in Bengkulu three minutes earlier detected in the skies of Saudi Arabia.
"In one minute, the waste can be moved thousands of miles. So be vigilant, but do not worry," he concluded.
