UAE reveals first image taken by Emirati-built KhalifaSat of Dubai icon

  • The photo of Palm Jumeirah, the famous man-made island that lies off the coast of Dubai in the Arabian Gulf, was revealed by Dubai’s Mohammed bin Rashid Space Center
  • The space center said the image was taken on Oct. 31 as KhalifaSat passed over the emirate

DUBAI: This image taken from space of Dubai’s Palm Jumierah is the first official photo taken by UAE satellite KhalifaSat.

The photo of Palm Jumeirah, the famous man-made island that lies off the coast of Dubai in the Arabian Gulf, was revealed by Dubai’s Mohammed bin Rashid Space Center this week.

The space center said the image was taken on Oct. 31 as KhalifaSat passed over the emirate.

And Dubai Media Office celebrated the exciting moment with a tweet of the image.

The satellite is being used to deliver high-quality images of Earth, assisting international government and private organizations with environmental monitoring, disaster relief and urban planning.

The UAE-built satellite was launched from Japan’s Tanegashima Space Center in October.

The UAE has previously sent two satellites into orbit - DubaiSat-1 and DubaiSat-2 - but KhalifaSat is the first to be entirely built in the Gulf state.

With construction beginning in 2013, the satellite took five years to be completed following an announcement by UAE’s Vice President and Dubai Ruler Sheikh Mohammed Bin Rashid Al Maktoum.

KhalifaSat is set to spend five years in a ‘low earth orbit’ before descending to Dubai’s Mohammed Bin Rashid Space Center.

Crater bigger than Paris is discovered under Greenland ice

  • The discovery was initially made in the 2015 but an international team of researchers has been working to verify the findings ever since
  • There would have been debris projected into the atmosphere that would affect the climate and the potential for melting a lot of ice

TAMPA: A massive iron meteorite smashed into Greenland as recently as 12,000 years ago, leaving a crater bigger than Paris that was recently discovered beneath the ice with sophisticated radar, researchers said Wednesday.
The crater is the first of its kind ever found on Greenland — or under any of the Earth’s ice sheets — and is among the 25 largest known on Earth, said the report in the journal Science Advances.
The impact of the 19-mile (31 kilometers) wide crater under the Hiawatha Glacier would have had significant ripple effects in the region, possible even globally, researchers said.
But its story is just beginning to be told.
“There would have been debris projected into the atmosphere that would affect the climate and the potential for melting a lot of ice, so there could have been a sudden freshwater influx into the Nares Strait between Canada and Greenland that would have affected the ocean flow in that whole region,” said co-author John Paden, courtesy associate professor of electrical engineering and computer science at Kansas University.
“The evidence indicates that the impact probably happened after the Greenland Ice Sheet formed, but the research team is still working on the precise dating.”
The discovery was initially made in the 2015 but an international team of researchers has been working to verify the findings ever since.
The initial finding was made with data from NASA’s Program for Arctic Regional Climate Assessment and Operation IceBridge.
More data was collected since then, using more advanced radar technology.
“So far, it has not been possible to date the crater directly, but its condition strongly suggests that it formed after ice began to cover Greenland, so younger than three million years old and possibly as recently as 12,000 years ago — toward the end of the last ice age” said co-author professor Kurt Kjaer from the Center for GeoGenetics at the Natural History Museum of Denmark.
Researchers plan to try and recover material that melted from the bottom of the glacier to learn more about its timing and effects on life on Earth at the time.
