BERLIN — A German satellite the size of a car re-entered the Earth's atmosphere early Sunday, officials said, adding they did not know yet if any debris had hit the Earth. The Roentgen Satellite (ROSAT), an x-ray observatory, made its re-entry between 0145 GMT and 0215 GMT on Sunday, the German Aerospace Centre (DLR) said in a statement. "There is currently no confirmation if pieces of debris have reached Earth's surface," the statement added. According to estimates cited last week, as many as 30 individual pieces weighing a total of 1.7 tonnes could reach the surface of the Earth. But Andreas Schuetz, spokesman for the DLR, said they would have to "wait for data in the next days" to know when and where the debris could fall. He said they did not currently know how far it was from the Earth. Last week, DLR officials said ROSAT was expected to return to Earth between October 22 and 23, travelling at a speed of around 28,000 kilometres (17,000 miles) per hour. Solar radiation, which heats up the Earth's atmosphere, increases the atmospheric drag and makes it hard to estimate the date of re-entry. As the spacecraft re-enters the atmosphere, the x-ray observatory would break up into pieces, some of which will burn up, they said. "The largest single fragment will probably be the telescope's mirror, which is very heat resistant," it added. However, statistically speaking, there is very little danger to humans from space junk, the experts have said. The debris will almost certainly fall in the sea or on an uninhabited piece of land. During its mission, ROSAT operated at distances of up to 585 kilometres above Earth's surface, but it has lost altitude since its decommissioning, and in June 2011 it was about 327 kilometres above the ground. A controlled re-entry was not possible at the end of its mission in 1999 because the spacecraft does not have a propulsion system on board, the officials said. ROSAT was launched in June 1990 to allow researchers to perform an all-sky survey of X-ray sources with an imaging telescope for the first time. Last month, a bus-sized US satellite that hurtled unpredictably toward Earth crossed over Africa and the northern Atlantic before plunging into the Pacific Ocean off California, NASA said. There were no sightings or reliable accounts of damage as the six-tonne Upper Atmosphere Research Satellite (UARS) fell from the sky. (AFP)

Muammar al-Qaddafi biography
Synopsis
Muammar al-Qaddafi was born in a Bedouin tent in 1942. He joined the
military and staged a coup to seize control of Libya in 1969, ousting
King Idris. Though his Arab nationalist rhetoric and socialist-style
policies gained him support in the early days of his rule, his
corruption, military interference in Africa, and record of human rights
abuses turned much of the Libyan population against him. Accused of
supporting terrorism in the last decade of his rule Qaddafi reached a rapprochement with
Western leaders, and Libya became a key provider of oil to Europe.
During the "Arab Spring" of 2011, NATO troops supported dissidents
attempting to overthrow Qaddafi's government. After months on the run,
on October 20, 2011, Qaddafi was killed in his hometown of Surt.
Early Life
Muammar
al-Qaddafi was born in 1942 in the town of Surt, in western Libya.
Raised in a Bedouin tent in the Libyan desert, he came from a tribal
family called the al-Qadhafah. At the time of his birth, Libya was an
Italian colony. In 1951, Libya gained independence under the
Western-allied King Idris. As a young man Qaddafi was influenced by
the Arab nationalist movement, and admired Egyptian leader Gamal Abdel
Nasser. In 1961 he entered the military college in the city of
Benghazi. He spent four months recieving military training in the
United Kingdom. After graduating, Qaddafi steadily rose through the
ranks of the military. As disaffection with King Idris grew, Qaddafi
became involved with a movement of young officers to overthrow the
king. A talented and charismatic man, Qaddafi political opposition
movement. On September 1, 1969, King Idris was overthrown while he was
abroad in Turkey for medical treatment. He was named commander in
chief of the armed forces and chairman of the Revolutionary Command
Council, Libya's new ruling body. At age 27, Qaddafi had become the
ruler of Libya.
Taking Control of Libya
Qaddafi's
first order of business was to shut down the American and British
military bases in Libya. He also demanded that foreign oil companies in
Libya share a bigger portion of revenue with the country. Qaddafi
replaced the Gregorian calendar with the Islamic one, and forbid the
sale of alcohol. Feeling threatened by a failed coup attempt by his
fellow officers in December 1969, Qaddafi put in laws criminalizing
political dissent. In 1970, he expelled the remaining Italians from
Libya, and emphasized what he saw as the battle between Arab
nationalism and western imperialism. He vocally opposed Zionism and
Israel, and expelled the Jewish community from Libya. Qaddafi's inner
circle of trusted people became smaller and smaller, as power was
shared by himself and a small group of family and friends. In these early days, Qaddafi sought to orient Libya away from the
West, and towards the Middle East and Africa. He involved the Libyan
military in several foreign conflicts, including in Egypt and Sudan,
and the bloody civil war in Chad. In 1974, Qaddafi published the Green Book,
an explanation of his political philosophy. The book describes the
problems with liberal democracy and capitalism, and promotes Qaddafi's
policies as the remedy. Qaddafi claimed that Libya boasted popular
committees and shared ownership, but in reality this was far from true.
Qaddafi had appointed himself or close family and friends to all
positions of power, and their corruption and crackdowns on any kind of
civic organizing meant much of the population lived in poverty.
Meanwhile, Qaddafi and those close to him were amassing fortunes in oil
revenue.
International Notoriety
Qaddafi's
ruling style was not just repressive, it was eccentric. He had a cadre
of female bodyguards, considered himself the king of Africa, erected a
tent to stay in when he traveled abroad, and dressed in strange
costume-like outfits. His bizzare antics often distracted from his
brutality, and earned him the nickname "the mad dog of the Middle
East." In addition to his oppressive rule at home, Qaddafi was despised by
much of the international community. His government was implicated in
the financing many anti-western groups, including some terror plots.
The Black Panthers, Nation of Islam, and the Irish Republican Army all
allegedly had links to Qaddafi. Because of Libya's links to Irish
terrorism, the United Kingdom cut off diplomatic relations with Libya
for more than a decade. In the most famous instance, Libya was
implicated in the 1988 Lockerbie bombing. A plane carrying 270 people
blew up near Lockerbie, Scotland, killing 270 people. In 1988, U.S.
warplanes carried out bombings in Libya, in a failed attempt to kill
Qaddafi.
Arab Spring
After
more than four decades in power, Qaddafi's downfall happened in less
than a year. In January of 2011, the Tunisian revolution forced out
longtime dictator Zine al-Abidine Ben Ali and set off the Arab Spring.
The next month Egyptian ruler Hosni Mubarak
was forced out, providiing a morale boost to protesters in several Arab
capitals. Despite the atmosphere of severe repression, demonstrations
broke out in Benghazi, and spread throughout the country. Qaddafi used aggressive force to try to suppress the protests, adn
the violence quickly escalated. Police and foreign mercenaries were
brought in to shoot at protesters, and helicopters were sent to bombard
protesters from the air. As casualties mounted, Libyans grew more
determined to see Qaddafi's ouster. As violence spread through the
country, Qaddafi made several rambling speeches on state television,
claiming the demonstrators were traitors, foreigners, al Qaeda, and
drug addicts. He urged his supporters to continue the fight, and small
groups of heavily armed loyalists battled against the rebels. By the end of February, the opposition had gained control over much
of the country, and the rebels formed a governing body called the
National Transitional Council. The opposition surrounded Tripoli, where
Qaddafi still had some support. Most of the international community
expressed support for the NTC, and called for the ouster of Qaddafi. At
the end of March, a NATO coalition began to provide support for the
rebel forces in the form of airstrikes and a no-fly zone. NATO's
military intervention over the next six months proved to be decisive.
In April, a NATO attack killed one of Qaddafi's sons. When Tripoli fell
to rebel forces, it was seen as a major victory for the opposition, and
a symbolic end for Qaddafi. In June, the International Criminal Court issued warrants for the
arrest of Qaddafi, his son Seif al-Islam, and his brother-in-law, for
crimes against humanity. In July, more than 30 countries recognized the
NTC as the legitimate government of Libya. Qaddafi had lost control of
Libya, but his whereabouts were still unknown.
Death
On
Thursday, October 20, Libyan officials announced the death of Muammar
al-Qaddafi near his hometown of Surt. Early reports had conflicting
accounts of his death, while some said he was killed in a gun battle,
and others said he was targeted by a NATO aerial attack. For months,
Qaddafi and his family had been at large, believed to be hiding in the
western part of the country, where they still had small pockets of
support. As news of the former dictator's death spread, Libyans poured
into the streets, celebrating the what many hailed as the culmination
of their revolution.
