Inside a huge crater in Israel's sun-baked Negev desert, a team wearing space suits ventures forth on a mission to simulate conditions on Mars.

The Austrian Space Forum has set up a pretend Martian base with the Israeli space agency at Makhtesh Ramon, a 500-metre (1,600-foot) deep, 40 kilometre (25 mile) wide crater.

The six so-called "analogue astronauts" will live in isolation in the virtual station until the end of the month.

"It's a dream come true," Israeli Alon Tenzer, 36, told AFP. "It's something we've been working on for years."

The participants -- from Austria, Germany, Israel, the Netherlands, Portugal and Spain -- all had to pass grueling physical and psychological tests.

During their mission, they will conduct tests including on a drone prototype that functions without GPS, and on automated wind- and solar-powered mapping vehicles.

The mission will also aim to study human behavior and the effect of isolation on the astronauts.

"The group's cohesion and their ability to work together are crucial for surviving on Mars," said Gernot Groemer, the Austrian mission supervisor.

"It's like a marriage, except in a marriage you can leave but on Mars you can't."

The Austrian Space Forum, a private organization made up of aerospace specialists, has already organised 12 missions, the most recent in Oman in 2018.

The Israel project is part of mission Amadee-20, which was expected to kick off last year but was delayed due to the Covid-19 pandemic.

The forum has partnered with Israeli research center D-MARS to construct the solar-powered base.

German astronaut Anika Mehlis, the only woman on the team, told AFP how happy she was to be part of the project.

"My father took me to the space museum when I was little," she said. "When I saw that the forum was looking for analogue astronauts, I told myself I had to apply."

Mehlis, a trained microbiologist, will study a scenario where bacteria from Earth infect potential life forms that may be found on Mars, saying this "would be a huge problem".

Visually, the surrounding desert resembles the Red Planet with its stony wilderness and orange hues, though thankfully not in terms of atmospheric conditions.

"Over here, we have temperatures of about 25-30 degrees Celsius, but on Mars the temperature is minus 60 degrees Celsius and the atmosphere is not fit for breathing," said Groemer.

The interior of the base is austere, with a small kitchen and bunk beds. Most of the space is reserved for scientific experiments.

NASA envisions the first human mission to Mars will launch in 2030.

"What we are doing here is preparing a large mission, the largest voyage our society has ever taken, as Mars and Earth are 380 million kilometres apart at their extreme point," said Groemer.

"I believe the very first human to walk on Mars is already born and we are the ship-builders to enable this journey."

Geologists have unearthed the world’s oldest known water, hidden deep beneath the surface of a Canadian mine for around 2.64 billion years.

The find, which was detailed in a 2016 study published in Nature, has profound implications not only for understanding the planet’s history but also for the possibility of life on other planets.

Within the depths of a Canadian mine nearly 3-kilometers below the Earth’s surface, geologists stumbled upon an unexpected and extraordinary find: a pocket of water believed to be over 2.6 billion years old.

What they found was a water source that had been sealed within the rock for nearly the entire span of Earth’s existence, offering researchers a unique opportunity to study a pristine, untouched ecosystem.

The sheer volume of the water was unexpected, defying initial assumptions and opening new avenues for scientific exploration.

What makes this discovery even more significant is the evidence of life that the water contained. Scientists analyzed the water for traces of sulfate and hydrogen, chemicals that provide clues to the presence of microbial life from ancient times.

The traces found in the water indicate that microorganisms once thrived in this environment, even in the absence of sunlight.

The water’s chemical composition also raised intriguing questions about the Earth’s geological processes.

Researchers discovered that the sulfate found in the water was not modern sulfate that had flowed down from surface waters but rather sulfate produced by a reaction between the water and rock.

Long Li, an assistant professor at the University of Alberta, explained the significance of the finding. “The sulfate in this ancient water is not modern sulfate from surface water flowing down. What we’ve found is that the sulfate, like the hydrogen, is actually produced in place by reaction between the water and rock,” he said. “What this means is that the reaction will occur naturally and can persist for as long as the water and rock are in contact, potentially billions of years.”

Perhaps the most astonishing moment of this discovery came when Professor Sherwood Lollar took the unprecedented step of tasting the ancient water.

While not typical in scientific studies, Lollar’s decision to taste the water was motivated by a desire to understand its unique properties.

“If you’re a geologist who works with rocks, you’ve probably licked a lot of rocks,” she told CNN.

She noted that she was looking for a salty taste, as saltier water tends to be older, and to her surprise, the ancient liquid was “very salty and bitter,” much saltier than seawater.

The saltiness and bitterness of the water confirmed that it had been isolated for an incredibly long time, allowing for the accumulation of minerals and other substances that contributed to its distinct taste. Lollar’s tasting of the water further emphasized the extraordinary nature of this find.

An unmanned Russian cargo spacecraft has a problem with an antenna so it will have to be manually docked when it reaches the International Space Station (ISS), Russia's Roscosmos state space corporation said in a statement.

A Soyuz-2.1a rocket launched the Progress MS-33 cargo spacecraft on Sunday from Baikonur in Kazakhstan ⁠but a problem with ⁠one of the KURS automated rendezvous antennas was identified, Roscosmos said.

Russian cosmonaut Sergei Kud-Sverchkov, the current ISS commander, will manually dock the cargo ship on ⁠Tuesday at about 13:35 GMT, Reuters quoted Roscosmos as saying.

"A manual approach of ships to the ISS is regularly practiced by cosmonauts in training," said Oleg Kononenko, head of Russia's Cosmonaut Training Center.

NASA said all other systems are operating as normal and that Roscosmos will continue troubleshooting the ⁠antenna.

The ⁠cargo ship is carrying about 2.5 tons of food, water, fuel, oxygen and supplies for the crew aboard the ISS.

There are currently seven crew aboard the ISS including Russians Kud-Sverchkov, Sergei Mikayev and Andrei Fedyaev, US astronauts Christopher Williams, Jessica Meir and Jack Hathaway, and France's Sophie Adenot.

The amount of heat trapped by the Earth reached record levels in 2025, with the consequences of such warming feared to last for thousands of years, the UN warned Monday.

The 11 hottest years ever recorded were all between 2015 and 2025, the United Nations' WMO weather and climate agency confirmed in its flagship State of the Global Climate annual report.

Last year was the second or third hottest year on record, at about 1.43 Celsius above the 1850-1900 average, the World Meteorological Organization said.

"The global climate is in a state of emergency. Planet Earth is being pushed beyond its limits. Every key climate indicator is flashing red," said UN Secretary-General Antonio Guterres.

"Humanity has just endured the 11 hottest years on record. When history repeats itself 11 times, it is no longer a coincidence. It is a call to act,” AFP quoted him as saying.

For the first time, the WMO climate report includes the planet's energy imbalance: the rate at which energy enters and leaves the Earth system.

Under a stable climate, incoming energy from the Sun is about the same as the amount of outgoing energy, the Geneva-based agency said.

However, the increase in concentrations of heat-trapping greenhouse gases -- carbon dioxide, methane and nitrous oxide -- "to their highest level in at least 800,000 years" has "upset this equilibrium", the WMO said.

"The Earth's energy imbalance has increased since its observational record began in 1960, particularly in the past 20 years. It reached a new high in 2025."

WMO chief Celeste Saulo said scientific advances had improved understanding of the energy imbalance and its implications for the climate.

"Human activities are increasingly disrupting the natural equilibrium and we will live with these consequences for hundreds and thousands of years," she said.

More than 91 percent of the excess heat is stored in the ocean.

"Ocean heat content reached a new record high in 2025 and its rate of warming more than doubled from 1960-2005 to 2005-2025," the WMO said.

Ocean warming has far-reaching consequences, such as degradation of marine ecosystems, biodiversity loss and reduction of the ocean carbon sink, the agency said.

"It fuels tropical and subtropical storms and exacerbates ongoing sea-ice loss in the polar regions."

The Antarctic and Greenland ice sheets have both lost considerable mass, and the annual average extent of Arctic sea ice in 2025 was the lowest or second-lowest ever recorded in the satellite era.

Last year, the global mean sea level was around 11 centimeters higher than when satellite altimetry records began in 1993.

Ocean warming and sea level rise are projected to continue for centuries.

WMO scientific officer John Kennedy said global weather is still under the influence of La Nina, a naturally occurring climate phenomenon that cools surface temperatures in the central and eastern equatorial Pacific Ocean. It brings changes in winds, pressure and rainfall patterns.

Conditions oscillate between La Nina and its warming opposite El Nino, with neutral conditions in between.

The warmest year on record, 2024, was around 1.55C above the 1850-1900 average, and started in a strong El Nino.

Forecasts indicate neutral conditions by the middle of 2026 with a possible El Nino developing before the end of the year, said Kennedy.

If so, "then we're likely to see maybe elevated temperatures again in 2027", he told a press conference.

The World Meteorological Organization's deputy chief, Ko Barrett, said the outlook was a "dire picture".

She said the WMO provided the evidence it sees, hoping that the information "will encourage people to take action".

But there was "no denying" that "these indicators are not moving in a direction that provides for a lot of hope", she said.

With war gripping the Middle East and fuel prices soaring, Guterres said the world should heed the alarm call.

"In this age of war, climate stress is also exposing another truth: our addiction to fossil fuels is destabilizing both the climate and global security," he said.

"Today's report should come with a warning label: climate chaos is accelerating and delay is deadly," he said.
