US, Russian, Japanese crew blasts off for International Space Station

Dec 17 : A trio of US and Japanese astronauts and a Russian cosmonaut blasted off from Kazakhstan on Sunday for a two-day trip to the International Space Station, a NASA TV broadcast showed.
Commander Anton Shkaplerov of Roscosmos and flight engineers Norishige Kanai of Japan Aerospace Exploration Agency and Scott Tingle of NASA lifted off from the Baikonur Cosmodrome at 1:21pm local time.
The crew will gradually approach the station, which orbits about 250 miles (400 km) above Earth, for two days before docking.
Shkaplerov, Kanai and Tingle will join Alexander Misurkin of Roscosmos and Mark Vande Hei and Joe Acaba of NASA, who have been aboard the orbital outpost since September.
Onboard cameras showed crew members making thumbs-up gestures after the blast-off. Also visible was a stuffed dog toy chosen by Shkaplerov’s daughter to be the spacecraft’s zero-gravity indicator.
Soyuz was safely in orbit about 10 minutes after the launch.

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.
