The crew of a NASA mission to Mars emerged from their craft after a yearlong voyage that never left Earth.
The four volunteer crew members spent more than 12 months inside NASA’s first simulated Mars environment at Johnson Space Center in Houston, coming out of the artificial alien enviroment Saturday around 5 p.m.
Kelly Haston, Anca Selariu, Ross Brockwell and Nathan Jones entered the 3D-printed habitat on June 25, 2023, as the maiden crew of the space agency’s Crew Health and Performance Exploration Analog project.
Haston, the mission commander, began with a simple, “Hello.”
“It’s actually just so wonderful to be able to say ‘hello’ to you all,” she said.
Jones, a physician and the mission medical officer, said their 378 days in confinement “went by quickly.”
The quartet lived and worked inside the space of 17,000 square feet (1,579 square meters) to simulate a mission to the red planet, the fourth from the sun and a frequent focus of discussion among scientists and sci-fi fans alike concerning a possible voyage taking humans beyond our moon.
The first CHAPEA crew focused on establishing possible conditions for future Mars operations through simulated spacewalks, dubbed “Marswalks,” as well as growing and harvesting vegetables to supplement their provisions and maintaining the habitat and their equipment.
They also worked through challenges a real Mars crew would be expected to experience including limited resources, isolation and delays in communication of up to 22 minutes with their home planet on the other side of the habitat’s walls, NASA said.
Two additional CHAPEA missions are planned and crews will continue conducting simulated spacewalks and gathering data on factors related to physical and behavioral health and performance, NASA said.
Steve Koerner, deputy director of Johnson Space Center, said most of the first crew’s experimentation focused on nutrition and how that affected their performance. The work was “crucial science as we prepare to send people on to the red planet,” he said.
“They’ve been separated from their families, placed on a carefully prescribed meal plan and undergone a lot of observation,” Koerner said.
“Mars is our goal,” he said, calling the project an important step in America’s intent to be a leader in the global space exploration effort.
Emerging after a knock on the habitat’s door by Kjell Lindgren, an astronaut and the deputy director of flight operations, the four volunteers spoke of the gratitude they had for each other and those who waited patiently outside, as well as lessons learned about a prospective manned mission to Mars and life on Earth.
Brockwell, the crew’s flight engineer, said the mission showed him the importance of living sustainably for the benefit of everyone on Earth.
“I’m very grateful to have had this incredible opportunity to live for a year within the spirit of planetary adventure toward an exciting future, and I’m grateful for the chance to live the idea that we must utilize resources no faster than they can be replenished and produce waste no faster than they can be processed back into resources,” Brockwell said.
“We cannot live, dream, create or explore on any significant timeframe if we don’t live these principles, but if we do, we can achieve and sustain amazing and inspiring things like exploring other worlds,” he said.
Science officer Anca Selariu said she had been asked many times why there is a fixation on Mars.
“Why go to Mars? Because it’s possible,” she said. “Because space can unite and bring out the best in us. Because it’s one defining step that ‘Earthlings’ will take to light the way into the next centuries.”

Saudi Arabia, UAE poised to become trade ‘super-connector hubs,’ WEF panel hears
- Agility’s Henadi Al-Saleh highlights that innovation, investment help countries to capitalize on disruption in global trade
LONDON: Saudi Arabia is on track to emerge as a “super-connector hub,” leveraging ongoing global trade disruption to its advantage, according to experts speaking at the World Economic Forum in Davos on Thursday.
Henadi Al-Saleh, chair of the board of directors at Agility, a global leader in supply chain services, highlighted the Gulf Cooperation Council’s significant investments in infrastructure as a driving force behind this transformation.
She said: “(In) the past few years, the level of activity, especially around cargo, has increased several fold.
“If I look at the GCC, where we have invested in warehouses, and at the Emirates in Saudi Arabia, one of our key platforms, (they are) set to become super-connector hubs.
“These countries are investing in infrastructure, doubling down, and the level of activity is increasing.”
Al-Saleh identified digitalization as a key value in this development, saying that “in a time with so much uncertainty, having that clarity and understanding, even when changes take place, it gives me visibility. (With the digital tools) I know what the rules (are) and (how) I need to adjust.”
She added: “That’s one critical aspect in which you see these super hubs benefiting.”
While the level of trade has continued to grow since the end of the pandemic, socioeconomic and political factors have continued to disrupt industry.
Experts have said that US President Donald Trump’s second term is expected to exacerbate the disruption, with the president supporting potential trade tariffs on multiple exporting nations.
Chile’s Minister of Foreign Affairs Alberto van Klaveren acknowledged the challenges but also pointed to opportunities arising from these shifts.
He said: “There are possibilities. Some economies are opening up. We signed the CEPA Agreement (Comprehensive Economic Partnership Agreement) with the Emirates. We are interested in Saudi Arabia.”
He explained that the importance of diversification was not only in export markets but also in the types of goods and services traded.
However, experts cautioned that ongoing trade disruption could significantly impact the global energy transition, particularly in the green energy sector.
Al-Saleh said: “There are certain segments of people, businesses and technologies (in the green energy market) that are paying a price.
“But this is where, I think, from the private sector, it’s incumbent upon them to continue. This is irrespective of what happens today in terms of tariffs. There is a long view, and we need to all manage towards that long view.”
According to World Trade Organization data, every nation relies on imports and exports for at least 25 percent of its goods. Given this interdependence, Al-Saleh argued, trade will remain indispensable despite ongoing disruption.
She said: “You need to focus on being agile and resilient. Those are critical elements, and the way to become agile and resilient is really to diversify and invest in technology.”
‘Killed, maimed, frozen to death’: UN Security Council meets to discuss plight of Gaza’s kids
- UN humanitarian chief Tom Fletcher tells council members of urgent need for donations to meet $4bn funding target for 2025
- The growing struggles of civilians in the West Bank must also not be ignored, he adds
NEW YORK CITY: The UN’s humanitarian chief on Thursday called for urgent action to protect children in Gaza and ensure their well-being amid the fragile ceasefire and ongoing humanitarian crisis in the territory.
Speaking during a meeting of the Security Council to discuss “the plight of children in the Gaza Strip,” Tom Fletcher emphasized the scale of suffering among Palestinian youngsters there as he urged the international community to ensure the ceasefire agreement between Israel and Hamas holds, and to scale up deliveries of humanitarian aid.
Fletcher said the ceasefire deal, brokered by Egypt, Qatar and the US, has brought a temporary reprieve for civilians, and is allowing Israeli hostages and detained Palestinians to be reunited with their families.
The truce has also enabled a surge in the amount of life-saving humanitarian assistance entering Gaza, providing a glimmer of hope for the millions of residents suffering as a result of the conflict.
“We can save more lives if all parties continue to honor the deal,” Fletcher said, thanking the mediators for their tireless efforts to facilitate the agreement and address the operational challenges in its implementation.
The 15 months of war between Israel and Hamas in Gaza have taken a profound toll on the children in the territory, the suffering of whom reached catastrophic proportions during that time, he added.
Fletcher painted a harrowing picture of the devastating effects of the conflict on the children of Gaza. Thousands lost their lives, an estimated 17,000 have been left without their families, and many more were injured or are suffering from malnutrition and psychological trauma.
He gave examples of the cruel conditions under which young people have been forced to lived, cited instances of unborn children perishing with their mothers, and detailed the desperate plight of more than 150,000 pregnant women and new mothers who are in urgent need of healthcare.
“The children of Gaza have been killed, starved, maimed, orphaned and separated from their families,” Fletcher said as he condemned the violence and deprivation. “A generation has been traumatized.”
Aside from the physical harm, children have endured deep psychological scars, with UNICEF estimating that 1 million youngsters are in need of mental health support for anxiety, depression and suicidal thoughts.
“Many have faced sexual violence,” Fletcher said. “Girls, who have endured the additional indignity of no access to menstrual care, have been left exposed and vulnerable.”
The war has had devastating effects on education as well, with schools destroyed and many children denied access to learning, he added.
But despite the overwhelming challenges, the international humanitarian community has made significant strides in the days since the ceasefire came into effect on Sunday, Fletcher said.
He highlighted the increased flow of aid into Gaza, including food, medical supplies and fuel, which has enabled critical services to resume or continue operating.
With the UN Relief and Works Agency at the forefront of the efforts, humanitarian agencies have scaled up their operations, delivering emergency shelter to protect people from the winter weather, food and life-saving medical care.
“We are getting supplies to designated emergency shelters and distribution centers across the Gaza Strip,” Fletcher said.
“We are delivering food parcels, distributing fuel to ensure that healthcare and water systems can function, and reopening bakeries to help meet basic nutritional needs.”
While these efforts are vital, Fletcher stressed that they will only be able continue with sustained funding and unimpeded access.
He appealed to UN member states to help replenish humanitarian stockpiles and called for greater involvement of the private sector to meet the needs of the 2 million residents of Gaza.
Fletcher stressed the urgent need for donations to help meet the $4.07 billion target of the UN’s 2025 Flash Appeal, to help address the needs of 3 million people in Gaza and the West Bank. Almost 90 percent of the total is needed for the humanitarian response in Gaza alone.
But while much of the international attention has focused on the Strip, Fletcher also warned the Security Council about the deteriorating situation in the West Bank, where violence and displacement have reached unprecedented levels since October 2023.
He described attacks by Israeli settlers on Palestinian villages, and ongoing military operations, particularly in Jenin, that have displaced thousands and caused significant damage to infrastructure.
“The situation in the West Bank must not be ignored,” Fletcher said. “We need to ensure that humanitarian aid and protection reach those in need, and that international law is respected.”
He once again urged council members to ensure the ceasefire holds, and that the flow of aid continues to those in need, in both Gaza and the West Bank. He called for the protection of Palestinian civilians, the release of all hostages and detainees, and unimpeded access for humanitarian workers.
“The children of Gaza are not collateral damage,” Fletcher said. “They are as deserving as children everywhere of security, education and hope. We must be there for them now, when they need us most.”
Trump pardons 23 anti-abortion protesters
WASHINGTON: US President Donald Trump signed pardons Thursday for 23 anti-abortion protesters whom the White House said were prosecuted under his predecessor Joe Biden’s administration.
“They should not have been prosecuted. Many of them are elderly people,” Trump told reporters in the Oval Office the day before a major anti-abortion march in Washington. “This is a great honor to sign this.”
Gaza hostage families conflicted over those not on release list
TEL AVIV: The families of Israeli hostages held in Gaza are trapped in limbo, two days before the second prisoner exchange of the Israel-Hamas ceasefire, with many having relatives both on the list to be freed and those who aren’t.
Among them is Silvia Cunio, an Argentine-Israeli from the Nir Oz kibbutz community. She has two sons in captivity, one of whom was taken along with his partner Arbel Yehud.
She is on the list — but the Cunio brothers, David and Ariel, are not.
They are among the 91 hostages taken captive during Hamas’s October 7, 2023, attack and still held in the Gaza Strip. Of that number, 34 are dead according to the Israeli military.
The ceasefire’s 42-day first phase began on Sunday with the release of three women hostages. A total of 33 captives are to be exchanged during the initial phase in return for around 1,900 Palestinian prisoners held in Israeli jails.
Standing in front of the office of Israeli Prime Minister Benjamin Netanyahu in Jerusalem, Cunio demanded that the ceasefire deal continue beyond the first phase to completion so she could see her sons again.
“I came here to say that I continue to fight for my children... to demand that they stop the war and don’t stop fighting for my children,” she said, wearing a T-shirt with their image on it.
Cunio presented herself as an untrammelled optimist, saying that her sons “will come back in good health. That is my hope and it is what keeps me going.”
Whenever she appears on TV, Cunio addresses her sons directly, just in case they might hear her.
“David, my darling, Ariel... I am here, I am fighting, I am doing everything I can. We love you. Be strong. We are here waiting for you.”
Another hostage relative, Sharon Sharabi, has two brothers Eli and Yossi in Gaza. Eli is presumed alive. The Israeli military said early last year that Yossi was dead.
As a man over 50, Eli Sharabi is on the list of 33 to be freed, alongside women, children and hostages who are ill or injured. The release of the remaining 61 people taken by Palestinian militants is dependent on further negotiations.
“As far as we know, Eli is alive. We have not received any statement from the security forces or the (military) confirming that Eli is no longer alive. So we want to maintain this optimism and pray that we will see him on his feet very soon,” said Sharabi.
Moved by the possibility, he allowed himself to imagine a reunion between his nearly octogenarian mother and his brother.
Yet, within moments, anxiety intruded.
If his brother Eli returns, Sharon Sharabi will have to tell him that his wife and two daughters were killed on October 7, 2023, and that their brother Yossi died in captivity.
Yossi and Eli were taken captive from Beeri, a kibbutz community where Eli’s wife and teenage daughters were found dead in their home.
Itzik Horn, 72, also an Argentine-Israeli, has similar contrasting emotions. He hopes for the release of his son Yair, 46, who is on the list of 33 because of his diabetes.
But there is also the pain of his other son, Eitan, 38, remaining in Gaza.
“They cut me in half. This is an impossible situation. One son might be released, and the other one isn’t,” Horn said.
Eitan was visiting his older brother in Nir Oz on October 7, when militants took the two of them hostage.
The kibbutz, less than three kilometers (two miles) from the Gaza border, was hit extremely hard during the Hamas attack. More than 30 people were killed in Nir Oz and 70 taken hostage, with 25 still in the Gaza Strip.
Horn was angry, insisting that “everyone has to return, including the bodies.”
He admitted that dark humor helped him cope with the pain.
“Yair inherited his diabetes from me and he was always mad at me (for it). Now, if he’s freed first because of his illness, he’ll be able to thank me,” he joked.
Asked what he would do if, after the first phase of the ceasefire the war resumed, Horn said: “I’m going to burn the country down... because that’s like signing their death sentence.”
How Saudi Arabia is tapping AI to monitor the environment and extreme weather
- AI enhances weather predictions, improving forecasts for heatwaves and flash floods critical for Saudi Arabia’s climate adaptation efforts
- KAUST’s Center of Excellence for Generative AI focuses on Earth observation technologies to address climate challenges like water scarcity
RIYADH: Since the launch of Vision 2030, technological innovation and sustainability have been central to Saudi Arabia’s transformative plan, with artificial intelligence emerging as a key tool to tackle a range of issues, including environmental challenges.
With nearly 90 percent of its territory covered by desert, the Kingdom is utilizing AI to combat land degradation, improve water resource management, and promote sustainable practices.
The King Abdullah University of Science and Technology has joined the global AI race by advancing generative AI research.
Its Center of Excellence for Generative AI adopts a multidisciplinary approach, focusing on technologies like multimodal foundation models and AI-assisted Earth observation systems to address challenges, including water scarcity and land degradation.
Prof. Matthew McCabe, director of KAUST’s Climate and Livability Initiative, told Arab News that AI has provided a pathway to revolutionize our understanding and interpretation of Earth systems, ushering in an era where data can be rapidly channeled to provide new knowledge and actionable insights.
“While GenAI has already impacted greatly on a number of domains, its application in the Earth and environmental sciences remains emerging,” McCabe said.
The center’s research focuses on developing AI tools for satellite imaging and Earth observation, enabling better monitoring of ecosystems. This includes using drones and satellite-based remote sensing technologies to track environmental changes in real-time.
Drones and satellite systems provide high-resolution data that is crucial for understanding ecological shifts in regions that were previously difficult to study. This allows for more effective land management, ecosystem restoration, and better predictions regarding weather patterns.
“We will be using remote sensing and other data sources to undertake ecosystem monitoring, helping to advance some of the goals and objectives of the Saudi Green Initiative,” McCabe said.

AI-driven solutions are already aiding the Saudi Green Initiative’s goals of planting 10 billion trees and rehabilitating 40 million hectares of degraded land by 2030, analyzing regional climate data, soil conditions, and water availability to identify optimal planting locations.
The Saudi Data and AI Authority, known as SDAIA, has partnered with several government entities to leverage AI solutions in support of the Saudi Green Initiative. These efforts aim to create innovative, data-driven strategies for combating climate change.
AI is also transforming climate forecasting in Saudi Arabia. Hylke Beck, assistant professor of climate analytics at KAUST, highlighted AI’s potential to predict extreme weather events like heatwaves and flash floods, which are expected to become more frequent and severe due to climate change.
Beck said AI models can uncover hidden relationships within weather data that traditional forecasting methods cannot, enabling more accurate and actionable forecasts.
He noted that these improved forecasts are critical for the Kingdom as it works to adapt to climate challenges, such as the severe heatwave that affected Makkah last June or the devastating floods in April across the UAE and Oman.
“With projections indicating that climate change will intensify and increase the frequency of heatwaves and flash floods, alongside an expected 32 percent population growth by 2050, the need to harness AI technology has never been more urgent,” Beck told Arab News.
Although there are currently few weather forecasting systems specifically designed for the region, and even fewer that incorporate AI models, Beck says these technologies have transformative potential.
However, Beck says building effective AI models requires access to extensive datasets.
“Government support in making this data accessible is essential for creating a more climate-resilient future,” he said.

• KAUST’s Center of Excellence for Generative AI focuses on Earth observation technologies to address climate challenges like water scarcity.
• Drones and satellites provide real-time data, aiding land management, ecosystem restoration, and environmental monitoring for the Saudi Green Initiative.
• AI models can uncover hidden relationships within weather data that traditional forecasting methods cannot, enabling more accurate and actionable forecasts.
Traditional weather models depend on equations created by scientists, but these equations can be limited by gaps in knowledge about certain weather patterns.
“These equations are imperfect because even the best meteorologists don’t fully understand all weather processes,” Berk said.
On the other hand, AI models analyze large amounts of data to find patterns, making predictions faster and more accurate. These are especially useful in areas where traditional systems struggle, like predicting thunderstorms, which are often harder to forecast accurately.
While traditional systems rely on expensive supercomputers, AI models can run effectively on regular computers, making them more affordable and accessible.
“These AI models can — and I believe will, in the not-too-distant future — fully replace current traditional models. However, they can also be integrated into them,” Beck said.
The Center of Excellence for Generative AI’s initiatives align with Vision 2030’s sustainability and innovation goals, collaborating with leading national entities like NEOM and Aramco, as well as international organizations like Meta and Nvidia to drive progress.
The center also addresses the shortage of generative AI talent in Saudi Arabia through training and upskilling programs for KAUST researchers, partners, and the wider community.
