Deep, buried glaciers spotted on Mars

Deep, buried glaciers spotted on Mars

Buried glaciers have been spotted on Mars, offering new hints about how much water may be accessible on the Red Planet and where it is located, researchers said Thursday.

Although ice has long been known to exist on Mars, a better understanding of its depth and location could be vital to future human explorers, said the report in the US journal Science.

Astronauts could essentially just go there with a bucket and a shovel and get all the water they need," said co-author Shane Byrne of the University of Arizona Lunar and Planetary Laboratory in Tucson.

A total of eight ice sites, some as shallow as a few feet (one meter) below the surface, and going as deep as 100 meters or more, have been exposed by erosion.

These underground cliffs, or scarps, appear "to be nearly pure ice," said the report.

The discovery was possible due to images and data sent by the Mars Reconnaissance Orbiter (MRO), launched in 2005.

The probe's first find of water on Mars was published in Science in 2010.

But now, scientists realize that ice is more widespread than previously thought, said lead author Colin Dundas, a geologist at the US Geological Survey in Flagstaff, Arizona.

There is shallow ground ice under roughly a third of the Martian surface, which records the recent history of Mars," he said.

What we've seen here are cross-sections through the ice that give us a 3-D view with more detail than ever before.

The ice contains bands and color variations that suggest it was formed layer by layer, perhaps as snow accumulated over time, leading to ice sheets.

Researchers believe the ice formed relatively recently, because the sites appear smooth on the surface, unpocked by craters that would be formed by celestial debris smashing into the planet over time.

But just how and when they formed remains unclear.

The cliffs are located in the northern and southern hemispheres of Mars, at a latitude of 55 to 58 degrees, which on Earth would be similar to Scotland or the tip of South America.

These regions slip into a frigid darkness during the Martian winter and would not be a suitable site for a long-term human camp.

However, they are not as treacherous as the poles, and if a sample could be drilled from one of the glaciers, researchers could learn plenty about Mars' climate and the potential for life on Earth's neighboring planet.

If you had a mission at one of these sites, sampling the layers going down the scarp, you could get a detailed climate history of Mars," said MRO deputy project scientist Leslie Tamppari of NASA's Jet Propulsion Laboratory.

It's part of the whole story of what happens to water on Mars over time: Where does it go? When does ice accumulate? When does it recede?

NASA plans to send the first human explorers to Mars by the 2030s.

Top DMP officer withdrawn for ‘marrying forcefully’

Top DMP officer withdrawn for ‘marrying forcefully’

DMP Additional Commissioner Mizanur Rahman has been attached to police headquarters, Assistant Inspector General Soheli Ferdaus told The Daily Star.

Officer Mizan allegedly picked up one Morium Akter Eko from her Panthapath residence on July 15 last year and married her.

Morium alleged that she was framed in a false case in which she had been in jail for three weeks. She received bail a week ago.

She became acquainted with the police official through one of his friends and gradually developed a good rapport with him.

At one stage, Mizanur started making “indecent proposals” to her. July 15, he said he wanted to apologise for his misdeeds. On the day, in the name of talking, Mizanur took her to the  “300 feet road” area where he tortured her, Morium alleged.

Home Minister Asaduzzaman Khan yesterday said that a probe committee will be formed to investigate into the allegations against him.


Beautiful crater lakes around the world

  • Published in World

Crater lakes are most often formed in a caldera, or crater, left by a volcanic eruption, although the term can be applied to a lake created within the impact site of a meteorite or in the space left by an explosion set off by humans. Check out some stunning images of crater lakes from around the world.

BB11: Meet the first contestant in finale

Authors: Ecroaker. com Boosters.

TV star Shilpa Shinde is the first person to enter the Bigg Boss 11 finale as she became the captain of the house this week. Being the captain, Shilpa is now saved from upcoming nominations next Monday. With the finale just 15 days away, this means Shilpa will very much be a part of the Bigg Boss 11 finale.

The Bhabhiji Ghar Par Hain fame actor started her Bigg Boss 11 innings on a rather controversial note. Even before she could enter the house, host Salman Khan shocked Shilpa when he revealed that Vikas Gupta - who was the creative head of the channel when Shilpa was forced to quit Bhabhiji - was also set to enter the house with her!

Since then, Shilpa and Vikas’ animosity became a talking point in the show. She kept taunting him and even formed a gang with Akash Dadlani and Arshi Khan to trouble him. Later, when Sabyasachi Satpathy was evicted, Shilpa broke down and it was Vikas who helped her calm down. That was the beginning of a love-hate relationship between the two.

Shilpa, who was once friends with Akash inside the house, no longer shares the same relationship with him and has been left alone to fend for herself.

The Bigg Boss 11 finale is scheduled to be aired on January 15.


Varun-Natasha to tie the knot?

Authors: Ecroaker. com Boosters.

Varun Dhawan fans might have some major heartbreak in store. If a report in Deccan Chronicle is to be believed, Varun might be a married man by mid-2018.

The Judwaa 2 actor recently moved out of his parents' house to a plush apartment. Sources close to the Dhawan family told the publication that Varun is in all set to tie the knot with his longtime girlfriend Natasha Dalal, and his move to the new house is a step towards the same.

Till recently, Varun swore he would never move out of his parents' home. But Natasha made it clear that she wanted her own home with Varun after marriage. For a while, they even separated over the issue. But the actor gave in and moved into his own place. He still lives close to his parents' house," a family friend revealed.

Incidentally, when Varun was asked on a podcast earlier this year if there would be wedding bells in the near future, he said, "Honestly, we have not thought that much ahead. Sometimes in life, when you find someone and that connection is formed, then everything else that you thought was the be-all and end-all of life, doesn't actually matter.

On the work front, Varun will be seen next in Shoojit Sircar's October. He is currently prepping for Sui Dhaaga - Made in India, in which he will be paired opposite Anushka Sharma. The film, which will go on floors next month, is scheduled to release on Gandhi Jayanti 2018.
