Meteor explosion in Russia, warning to Indonesia

Ria Novosti said officials at The Chelyabinks pass and exploding meteors allegedly crashed into a lake.

JAKARTA, KOMPAS.com – "meteor explosion in Russia is a warning to us," said astronomer ITB, Hakim l. Malasan.

Meteor explosion at Chelyabinsk, Russia on Friday (15/02/2013) yesterday took place outside the allegations, leading to about 1,200 people injured. The judge hopes the incident can raise people's awareness will be the possibility of a similar case in Indonesia.

"Hopefully in future public awareness will be increased, not only for a moment (after the event occurred)," said Judge when contacted Kompas.com today (17/02/2013).

The judge added, Indonesia with vast territory and the existence of a threat of lacing the asteroid that could happen at any time. Thus, the concept of protection need to be built of the air (spaceguard) is serious.

"The Government, through EIGHT, should begin seriously building up the concept of spaceguard. As long as this region protection is focused on the matra (dimensions) land and maritime (sea). Matra Aerospace was noteworthy. Governments need to develop the concept of sky patrol in Indonesia. " The Judge Said.

Currently, Indonesia has yet to have an early warning technology and space patrol, which can detect the potential fall of the asteroid or other heavenly bodies (e.g., space junk).

Thomas Djamaluddin, astrophysicist of flight and Space Agency (LAPAN) said National, tenologi to support the supervision of natariksa very expensive objects. In the world, recently developed countries such as America, Japan, and countries in Europe that have it.

"There are goals towards there, but is currently not possible to be realized because of the huge funds needed to build it. This is also related to the budget, "said Deputy Science, learning, and Aerospace Information EIGHT.

Thomas said, "to get around it, the Government is conducting international cooperation with other countries in the world, through the mechanism of data exchange (data sharing)".

Said Thomas, space patrol and early warning systems to anticipate a disaster due to lacing asteroids and other heavenly bodies built for the benefit of mankind throughout the world without any territorial restrictions.

When asteroids or astronomical objects that fall to earth are large, a disaster which may occur not only override the country that became the hit location but will also have an effect on surrounding countries. (Fifi Dwi Pratiwi)

Why Not A Predicted Meteor Blast Russia Previously

Ria Novosti said officials at The Chelyabinks pass and exploding meteors allegedly crashed into a lake.

JAKARTA, KOMPAS.com -human space technology today, especially from developed countries such as the United States and Russia, capable of detecting objects in space that could potentially for mashing. But, on a meteor explosion in Russia Friday (15/2/2013), humans apparently "latest soccer news directly".
The question now is, why humans and technology could be latest soccer news directly?

"There's a meteor exploding in the detection of Russia may be due to the limitations of the current system in detecting celestial objects are small with long distances," said Dr. Hakim l. Malasan., astronomer, ITB, when contacted by the Kompas.com, Tuesday (17/2/2013).

The judge, expressing space objects categorized when resized smaller less than 30 meters.

The same thing also put forth a Space Agency astrophysicist and National Flight (EIGHT), Thomas Djamaluddin. "The size of the asteroid that is too small to make its existence is difficult to detect," he said.

Thomas revealed, extraterrestrial objects near the Earth currently detected using optical methods. Object detection by this method is based on the brightness of the object. These methods have limitations in detecting objects smaller space.

"Detect small asteroids is difficult because these objects are very faint especially if its distance away from Earth, so often escapes observation," said Thomas, who also contacted yesterday.

"Even if detected, it is usually the asteroids had been located at a distance which is very close to the Earth and we are difficult to do much to avoid it. In contrast to the asteroid 2012 DA14 is relatively easy to spot, "he added.

Asteroid 2012 DA14 known passing near Earth on Saturday (16/2/2013) early morning time Indonesia.

According to Thomas, the relatively small-sized asteroids that could potentially hit the Earth was ever detected. Unfortunately, this charge was accidentally. The Asteroid that hit the Earth in the year 2008, precisely in the area of Sudan, Africa.

The Asteroid that crashed in Sudan smaller, diameterya only 6 yards. Taken into account, the asteroid fell in 19 hours after detected. The location of the collision have also been determined. And, the collision does happen as predicted.

Thomas adds, in addition to its small size, the speed of the meteor when it crashed to Earth is also one of the factors is not the detection of meteor that exploded in Russia.

"The average speed when asteroids fall could reach 20 – 30 km/s or the equivalent of 70,000 km – 100,000 km/h. Therefore when unidentified asteroid at a distance of 2 million miles, it means that the asteroid had been very close to Earth, "said Thomas.

The latest information from the official NASA portal size meteorite exploded in Russia by 17 metres (previously 15 metres) and weighs 10,000 tons. Although classified meteorites are small in size, this is larger when compared with the meteor that crashed off the coast of Bone in 2008. The Flash causes 200,000 square metres of broken glass at the disaster site, and injuring about 1,200 people.

Judges and Thomas explains, the damage that occurs in a location not caused by collision or meteor fragments, however pleh shock wave that appears when the meteor burst. (Fifi Dwi Pratiwi)
