The NASA astronaut knocks loudly three times on a what appears to be a nondescript door, and calls cheerfully: “You ready to come out?”
The reply is inaudible, but beneath his mask he appears to be grinning as he yanks the door open and four scientists who have spent a year away from all other human contact, simulating a mission to Mars, spill out to cheers and applause.
Anca Selariu, Ross Brockwell, Nathan Jones and team leader Kelly Haston have spent the past 378 days sealed inside a “Martian” habitat in Houston, Texas, as part of NASA’s research into what it would take to put humans on the Red Planet.

They have been growing vegetables, conducting “Marswalks,” and operating under what NASA terms “additional stressors,” such as communication delays with “Earth,” isolation and confinement. It is the kind of experience that would make anyone who lived through COVID-19 lockdowns shudder — but all four were beaming on Saturday as they re-emerged, their hair slightly more unruly and their emotion apparent.
“Hello. It’s actually so wonderful just to be able to say hello to you,” Haston, a biologist, said with a laugh.
“I really hope I don’t cry standing up here in front of all of you,” Jones, an emergency room doctor, said as he took to the microphone — and nearly doing just that several moments later as he spotted his wife in the crowd.
The habitat, dubbed Mars Dune Alpha, is a 3D printed 160m2 facility, complete with bedrooms, a gym, common areas and a vertical farm to grow food. An outdoor area, separated by an airlock, is filled with red sand and is where the team donned suits to conduct their “Marswalks,” although it is still covered rather than being open air.
“They have spent more than a year in this habitat conducting crucial science, most of it nutrition-based and how that impacts their performance ... as we prepare to send people on to the Red Planet,” said Steve Koerner, deputy director at NASA’s Johnson Space Center. “I’m very appreciative.”
This mission is the first of a series of three planned by NASA, grouped under the title Crew Health and Performance Exploration Analog.
A fire caused by a burst gas pipe yesterday spread to several homes and sent a fireball soaring into the sky outside Malaysia’s largest city, injuring more than 100 people. The towering inferno near a gas station in Putra Heights outside Kuala Lumpur was visible for kilometers and lasted for several hours. It happened during a public holiday as Muslims, who are the majority in Malaysia, celebrate the second day of Eid al-Fitr. National oil company Petronas said the fire started at one of its gas pipelines at 8:10am and the affected pipeline was later isolated. Disaster management officials said shutting the
US Vice President J.D. Vance on Friday accused Denmark of not having done enough to protect Greenland, when he visited the strategically placed and resource-rich Danish territory coveted by US President Donald Trump. Vance made his comment during a trip to the Pituffik Space Base in northwestern Greenland, a visit viewed by Copenhagen and Nuuk as a provocation. “Our message to Denmark is very simple: You have not done a good job by the people of Greenland,” Vance told a news conference. “You have under-invested in the people of Greenland, and you have under-invested in the security architecture of this
UNREST: The authorities in Turkey arrested 13 Turkish journalists in five days, deported a BBC correspondent and on Thursday arrested a reporter from Sweden Waving flags and chanting slogans, many hundreds of thousands of anti-government demonstrators on Saturday rallied in Istanbul, Turkey, in defence of democracy after the arrest of Istanbul Mayor Ekrem Imamoglu which sparked Turkey’s worst street unrest in more than a decade. Under a cloudless blue sky, vast crowds gathered in Maltepe on the Asian side of Turkey’s biggest city on the eve of the Eid al-Fitr celebration which started yesterday, marking the end of Ramadan. Ozgur Ozel, chairman of the main opposition Republican People’s Party (CHP), which organized the rally, said there were 2.2 million people in the crowd, but
JOINT EFFORTS: The three countries have been strengthening an alliance and pressing efforts to bolster deterrence against Beijing’s assertiveness in the South China Sea The US, Japan and the Philippines on Friday staged joint naval drills to boost crisis readiness off a disputed South China Sea shoal as a Chinese military ship kept watch from a distance. The Chinese frigate attempted to get closer to the waters, where the warships and aircraft from the three allied countries were undertaking maneuvers off the Scarborough Shoal — also known as Huangyan Island (黃岩島) and claimed by Taiwan and China — in an unsettling moment but it was warned by a Philippine frigate by radio and kept away. “There was a time when they attempted to maneuver
