A long time in the making
Curiosity landed in Gale Crater on August 6, 2012. More than 12 years later, the rover has driven over 21 miles (34 kilometers) to ascend Mount Sharp, which is within the crater. The feature’s many layers preserve millions of years of geological history on Mars, showing how it shifted from a wet to a dry environment.

Perhaps one of the most valuable samples Curiosity has gathered on its mission to understand whether Mars was ever habitable was collected in May 2013.

The rover drilled the Cumberland sample from an area within a crater called Yellowknife Bay, which resembled an ancient lake bed. The rocks from Yellowknife Bay so intrigued Curiosity’s science team that it had the rover drive in the opposite direction to collect samples from the area before heading to Mount Sharp.
Since collecting the Cumberland sample, Curiosity has used SAM to study it in a variety of ways, revealing that Yellowknife Bay was once the site of an ancient lake where clay minerals formed in water. The mudstone created an environment that could concentrate and preserve organic molecules and trapped them inside the fine grains of the sedimentary rock.

Freissinet helped lead a research team in 2015 that was able to identify organic molecules within the Cumberland sample.

The instrument detected an abundance of sulfur, which can be used to preserve organic molecules; nitrates, which are essential for plant and animal health on Earth; and methane composed of a type of carbon associated with biological processes on Earth.

“There is evidence that liquid water existed in Gale Crater for millions of years and probably much longer, which means there was enough time for life-forming chemistry to happen in these crater-lake environments on Mars,” said study coauthor Daniel Glavin, senior scientist for sample return at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in a statement.

While the Cumberland sample may contain longer chains of fatty acids, SAM is not designed to detect them. But SAM’s ability to spot these larger molecules suggests it could detect similar chemical signatures of past life on Mars if they’re present, Williams said.

“Curiosity is not a life detection mission,” Freissinet said. “Curiosity is a habitability detection mission to know if all the conditions were right … for life to evolve. Having these results, it’s really at the edge of the capabilities of Curiosity, and it’s even maybe better than what we had expected from this mission.”

Before sending missions to Mars, scientists didn’t think organic molecules would be found on the red planet because of the intensity of radiation Mars has long endured, Glavin said.
Curiosity won’t return to Yellowknife Bay during its mission, but there are still pristine pieces of the Cumberland sample aboard. Next, the team wants to design a new experiment to see what it can detect. If the team can identify similar long-chain molecules, it would mark another step forward that might help researchers determine their origins, Freissinet said.

“That’s the most precious sample we have on board … waiting for us to run the perfect experiment on it,” she said. “It holds secrets, and we need to decipher the secrets.”

Briony Horgan, coinvestigator on the Perseverance rover mission and professor of planetary science at Purdue University in West Lafayette, Indiana, called the detection “a big win for the whole team.” Horgan was not involved the study.
“This detection really confirms our hopes that sediments laid down in ancient watery environments on Mars could preserve a treasure trove of organic molecules that can tell us about everything from prebiotic processes and pathways for the origin of life, to potential biosignatures from ancient organisms,” Horgan said.

Dr. Ben K.D. Pearce, assistant professor in Purdue’s department of Earth, atmospheric, and planetary sciences and leader of the Laboratory for Origins and Astrobiology Research, called the findings “arguably the most exciting organic detection to date on Mars.” Pearce did not participate in the research.

Arctic auroras
ethena
For getting around during winter, the Inuit here nowadays prefer snowmobiles, although they still keep their sled dogs. During winter they’ll offer intrepid visitors, wrapped up warm against the deep-freeze temperatures, dog-sledding jaunts. These can last either an hour or be part of expeditions over several days, sometimes with the added experience of learning how to build an igloo. Sisimiut on the west coast and Tasilaq in the southeast are active winter centers for dog sledding.

Winter’s most stellar attraction, though, is northern lights watching. With little urban light pollution, Greenland is a dark canvas for spectacular displays, and aurora borealis-watching vacations are becoming more popular.

Staying outdoors, Greenland is developing a reputation among adventure enthusiasts: from long-distance skiing expeditions and heliskiing on the icecap to hiking the 100-mile-long Arctic Circle Trail from Kangerslussuaq, where firearms need to be carried for warning shots in case of polar bear encounters.

Life is definitely changing here. The climate crisis is eating away at its icecap and Greenland may well end up as a pawn in a game of geopolitical chess. But for now, the bright glare of international attention should shine a favorable light on one of the wildest travel destinations on Earth.

Travel writer Mark Stratton is an Arctic specialist who has traveled to Greenland six times and counting. He’s marveled at the aurora borealis, sailed to Disko Island, dog-sledded with the Inuit, and once got stuck in an icefloe.

Tbilisi, Georgia — Jailed journalist Mzia Amaghlobeli gets weaker every day as her hunger strike has reached three weeks in Rustavi, a town near the Georgian capital of Tbilisi, her lawyer says. Now the 49-year-old is having difficulty walking the short distance from her cell to the room where they usually meet, and human rights officials, colleagues and family fear for her life.
kra20 at
Amaghlobeli was arrested Jan. 12 during an anti-government protest in the coastal city of Batumi, one of over 40 people in custody on criminal charges from a series of demonstrations that have hit the South Caucasus nation of 3.7 million in recent months.
kra27 at
The political turmoil follows a parliamentary election that was won by the ruling Georgian Dream party, although its opponents allege the vote was rigged.

Protests highlight battle over Georgia's future. Here's why it matters.
Its outcome pushed Georgia further into Russia's orbit of influence. Georgia aspired to join the European Union, but the party suspended accession talks with the bloc after the election.

As it sought to cement its grip on power, Georgian Dream has cracked down on freedom of assembly and expression in what the opposition says is similar to President Vladimir Putin's actions in neighboring Russia, its former imperial ruler.

Americans nearing retirement and recent retirees said they were anxious and frustrated following a second day of market turmoil that hit their 401(k)s after President Donald Trump’s escalation of tariffs.

[url=https://kra35at.com]kraken35.at[/url]
As the impending tariffs shook the global economy Friday, people who were planning on their retirement accounts to carry them through their golden years said the economic chaos was hitting too close to home.

[url=https://kraken14-at.com]kra14 cc[/url]
Some said they are pausing big-ticket purchases and reconsidering home renovations, while others said they fear their quality of life will be adversely affected by all the turmoil.

“I’m just kind of stunned, and with so much money in the market, we just sort of have to hope we have enough time to recover,” said Paula, 68, a former occupational health professional in New Jersey who retired three years ago.

Paula, who spoke on the condition of anonymity because she feared retaliation for speaking out against Trump administration policies, said she was worried about what lies ahead.

“What we’ve been doing is trying to enjoy the time that we have, but you want to be able to make it last,” Paula said Friday. “I have no confidence here.”

Trump fulfilled his campaign promise this week to unleash sweeping tariffs, including on the United States’ largest trading partners, in a move that has sparked fears of a global trade war. The decision sent the stock market spinning. On Friday afternoon, the broad-based S&P 500 closed down 6%, the tech-heavy Nasdaq dropped 5.8%, and the Dow Jones Industrial Average fell more than 2,200 points, or about 5.5%.
