Astronauts at the International Space Station have completed the first of a series of spacewalks to carry out urgent repairs.

The two Americans on the crew went outside the station and removed a pump containing a faulty valve.

It is the first of three possible spacewalks needed to mend the station’s critical cooling system.

Half of the system automatically shut down last week after detecting abnormal temperatures.

Nasa said the situation was potentially serious but not life-threatening.

The six-man crew had to turn off all non-essential equipment because of the malfunction.

Faulty pump

The two astronauts, Rick Mastracchio and Mike Hopkins, began their spacewalk – 418km (260 miles) above the Earth’s surface – at about 12:00 GMT and were outside the space station for nearly six hours.

Researchers say they have discovered a large reservoir of melt water that sits under the Greenland ice sheet all year round.

The scientists say the water is stored in the air space between particles of ice, similar to the way that fruit juice stays liquid in a slush drink.

The aquifer, which covers an area the size of Ireland, could yield important clues to sea level rise.

The research is published in the journal, Nature Geoscience.

The melting of the Greenland ice sheet has been a significant contributor to a rise in sea levels over the past 100 years.

“The water is stored in the air space between the ice particles, like the juice in a snow cone”

Prof Rick Forster University of Utah

According to the latest report from the Intergovernmental Panel on Climate Change, the ice sheet lost 34 billion tonnes of ice per year between 1992 and 2001 – but this increased to 215 billion tonnes between 2002 and 2011

Scientists still have many unanswered questions about the direction and speed and ultimate destination of this melted water.

Ice free liquid

This new research finds that a significant amount is stored in partially compacted snow called firn.

In the spring of 2011, researchers drilled deep into this slushy layer and to their surprise, found liquid water flowing back to the surface even though air temperatures were -15 degrees C.

BBC News – Storm rushing towards UK

http://www.bbc.co.uk/news/uk-25488198#threeG

2 hours ago

A rapidly-developing weather system is rushing across the Atlantic towards the UK under the influence of an upper-level jet stream of more than 280mph, according to weather forecaster Peter Gibbs.

He warned of strong winds and heavy rain in the UK in the run-up to Christmas, with snow in Scotland.
