Mars makes closest approach to Earth in 15 years

Mars

Earth’s neighboring planet, Mars, is closer than it has been in the past 15 years, offering unusually bright views of the Red Planet’s auburn hues.

“The Red Planet and Earth haven’t been this close since 2003, and won’t be again until 2035,” NASA said.

Astronomers around the world trained their telescopes on the sky on July 31, when the Red Planet was 35.8 million miles (57.6 million kilometers) away.

One popular public viewing spot was the Griffith Observatory in Los Angeles, where Mars was visible with the naked eye as a bright orange spot in the sky, according to a live broadcast held to mark the celestial event.

“Mars is invading us tonight,” said observatory director Ed Krupp.

The nearest point to Earth in Mars’ elliptical orbit came at around 1100 GMT on Tuesday, NASA said.

Astronomers are interested in Mars’ travel path because it helps decide the best times for spacecraft to launch.

When the Sun, Earth and Mars are lined up, with Earth sitting in between, a phenomenon called “opposition” is in effect, giving the brightest view of Mars.

But also, “around the time of opposition, a planet is at its closest distance to Earth for a given year,” the US space agency explained.

Since the Earth and Mars align in opposition about every two years, “this is why most NASA missions to the Red Planet are at least two years apart -– to take advantage of the closer distance.”

This year’s close approach is not a record-breaker.

The minimum distance from the Earth to Mars is about 33.9 million miles (54.6 million kilometers), and is rarely achieved.

The last closest approach was in 2003, when Mars was 34.6 million miles (55.7 million kilometers) from Earth “and the closest it had been in nearly 60,000 years,” said NASA.

Another close encounter like 2003’s will not happen until the year 2287.

For those who missed the closest approach, not to worry. Mars will still be visible in the night sky for the next few months.

Accountability court hears assets case against Ishaq Dar

ISLAMABAD: An accountability court in Islamabad on Wednesday resumed the hearing of a reference filed against former finance minister Ishaq Dar by the National Accountability Bureau (NAB) for allegedly accumulating assets beyond his known sources of income.  Judge Muhammad Bashir is recording the statement of a prosecution witness, Ishtiaq Ahmed. At the previous hearing, the accountability judge had reserved his verdict on an application filed by two co-accused seeking acquittal in the case. Naeem Mehmood and Mansoor Rizvi, who are directors of Dar’s companies, had filed the application requesting the judge to exonerate them from all charges for want of evidence. Qazi Misbah, the counsel for the two co-accused, contended the prosecution has failed to provide compelling evidence to prove the allegations leveled against his clients. The third co-accused President National Bank of Pakistan (NBP), Saeed Ahmed, had already filed an application before the court for his acquittal wh...

Qatar to hike minimum wage ‘by end of year’

DOHA: Qatar could increase the minimum wage for migrant workers by the end of 2018, unions predicted on Monday, as the 2022 World Cup host seeks to push through labour reforms. It would be the first change to the monthly wage since its introduction by the gas-rich Gulf state last November. “By the end of the year we expect a new minimum wage to be set, that’s good news,” said Sharan Burrow, general secretary of the International Trade Union Confederation. Burrow did not name a figure but said the new wage would be calculated by assessing a “basket of goods”. She was speaking after meeting Qatar’s labour minister, Issa al-Jufali al-Nuaimi, and other government officials in Doha over the past two days. The minimum wage was set at 750 riyals a month ($206, 170 euro) on its introduction. In addition to the salary, labourers receive free accommodation, food and healthcare plans, covered by employers. The 750-riyal figure has been criticised as too low. “We believe it is not good e...
