"Dust threatening Satellite"
Total Waste Antariksa
Achieves 12,947
JAKARTA, FRIDAY-Board Satellite Cosmos rocket launchers belonging to Russia in 2445 is estimated to fall on the earth in March 2009. The same will happen in two months on the fraction Iridium Cosmos 2251 and the crash on 10 February 2009.Opportunities fall serpihan satellites are quite large in Indonesia because the eighth Bentang place the equatorial regions of the country. This was the Head of The Center for Science Antariksa Aviation Institute and the National Antariksa Sri Kaloka, Friday (20 / 2).
Abdul Rachman, researchers at the center, explains, based on data from the Department of Defense the United States, Cosmos 2445 which will fall later in March is a rocket body or SL-6 RB that can not be controlled.
"While this may not be the time and location of the fall of the satellite, but is usually five to three days before," he said.
The Cosmos 2251 has a control system to direct the location of the fall of satellites. Satellite is owned by Russia is not active though still intact.
Tuesday last week collide with the satellite is still the active function. Due to the collision, said Sri, cause many serpihan, 22 of them terpantau chip size is relatively large, above 10 centimeters square.
Fragment was circulating on the equatorial region, and several times through the above Indonesia. "Today the strip is above terpantau through Sumatra, continued to move eastward," he said yesterday.
In addition to continued outstanding encircle the equator, serpihan down the atmosphere of the gradual approach. Movement is monitored every hour per day.
Although the form of scrap, fall to the surface of the earth will melesat in a very high speed. "Danger in the fall when the chip toll road, the vehicles there. As a result, can cause a collision beruntun, "he said.
However, with the object, the security measures can be done before the incident, eg close to the toll road.
In the future, possibly in the fall of garbage outer face of the earth more. To 27 January, 7789 is the number of serpihan-sized above 10 cm-satellite work and do not work amounted to 3338, and a rocket body 1820-total 12,947.
Satellite crash
Meanwhile, the collision Iridium 33 weight 560 kg and 2251 Cosmos Iridium occurs when moving 7.5 kilometers per second to the north, while the Cosmos 2251 (900 kg) to the south with the same rate. Collision occurs with the rate 6.7 km per second, or 24,000 km per hour.
Collision occurred on 10 February at 23:56 at an altitude of 788 km above Siberia, Russia. Observations indicate that the two objects collide and are broken serpihannya divided into two groups with a total serpihan cloud serpihan more than 700.
