Researchers have shed light on the ages of ice deposits reported in the area of the Moon’s south pole — information that could help identify the sources of the deposits and help in planning future human exploration.

The study published in the journal Icarus suggests that while a majority of those deposits are likely billions of years old, some may be much more recent.


“The ages of these deposits can potentially tell us something about the origin of the ice, which helps us understand the sources and distribution of water in the inner solar system,” said study lead author Ariel Deutsch from Brown University.

“For exploration purposes, we need to understand the lateral and vertical distributions of these deposits to figure out how best to access them. These distributions evolve with time, so having an idea of the age is important,” Deutsch said.

For the study, Deutsch worked with Professor Jim Head, and Gregory Neumann from the NASA Goddard Space Flight Centre.

Using data from NASA’s Lunar Reconnaissance Orbiter, which has been orbiting the Moon since 2009, the researchers looked at the ages of the large craters in which evidence of south pole ice deposits was found.

To date the craters, researchers count the number of smaller craters that have accrued inside the larger ones.

Scientists have an approximate idea of the pace of impacts over time, so counting craters can help establish the ages of terrains.

The majority of the reported ice deposits are found within large craters formed about 3.1 billion years ago or longer, the study found.

The deposits have a patchy distribution across crater floors, which suggests that the ice has been battered by micrometeorite impacts and other debris over a long period of time.

If those reported ice deposits are indeed ancient, that could have significant implications in terms of exploration and potential resource utilisation, the researchers said.

While the majority of ice was in the ancient craters, the researchers also found evidence for ice in smaller craters that, judging by their sharp, well-defined features, appear to be quite fresh.

That suggests that some of the deposits on the south pole got there relatively recently.

The best way to find out for sure is to send spacecraft to get some samples which event appears to be on the horizon. NASA’s Artemis programme aims to put humans on the Moon by 2024, and plans to fly numerous precursor missions with robotic spacecraft in the meantime, the researchers said. (IANS)

The world's largest producer of ketchup announced the Packet Roller, a ketchup bottle-shaped gadget that allows users to squeeze the most out of a condiment packet, CNN reported.

Heinz has just rolled out a new product that the condiment company says is the "biggest innovation in sauce since the packet itself." Earlier this month, the world's largest producer of ketchup announced the Packet Roller, a ketchup bottle-shaped gadget that allows users to squeeze the most out of a condiment packet, CNN reported.

"Do not click 'purchase' unless you are prepared to change everything about the way you sauce," the Heinz Packet Roller website says. The roller goes for $5.70. The roller is pocket-sized, can be added to a keychain, and features a packet corner cutter.

Swiss tennis ace Roger Federer, is recovering from a right-knee surgery he underwent last month.

Swiss tennis ace Roger Federer, who is recovering from a right-knee surgery he underwent last month, said on Sunday that it was a difficult process to decide whether to undergo a third right-knee surgery after having two last year. But following Wimbledon, where he was "really unhappy" with his performance in reaching the quarterfinals, Federer opted to go through with it.

Federer, who made a late decision to attend this year's Laver Cup in Boston -- a tournament held between teams from Europe and the rest of the world -- said on the sidelines of the event that the recovery and rehabilitation are "going to take me a few more months and then we'll see how things are at some point next year". "The reception I've received, everybody is so upbeat that I'm here. They wish me all the best and they don't even see the crutches. They just want me to be good again and enjoy the weekend," Federer said in an interview for the event with former world No. 1 Jim Courier.

"I've seen some incredible tennis, some great matches and it's been wonderful. I'm really happy I made the trip," the winner of 20 majors was quoted as saying by atptour.com. On why he opted for a third surgery, the tennis ace said, "I was just nowhere near where I wanted to be to play at the top, top level. But I tried my best and at the end... too much is too much. Now I've just got to take it step by step," Federer said.

Cleopatra, was regarded as a great beauty, to preserve her skin, she took her daily bath in donkey milk. Besides, Hippocrates, the father of medicine, prescribed donkey milk for various diseases including fever, wounds, etc. To add to these benefits, donkey milk has four times the amount of Vitamin C than cow's milk has. So, it's no secret that donkey milk is a powerhouse of nutrients for both the skin and body.

Used for Anti-Ageing and Healing
The milk contains essential fatty acids that work as powerful anti-ageing and healing properties. These fatty acids blur the wrinkles on the skin and help to regenerate damaged skin. Plus, donkey milk also contains anti-bacterial properties which are effective in healing skin irritation and redness.
