Tracing a meteorite: Niger outraged over sale of a fragment from Mars
The sale of the largest Martian meteorite ever found has angered Niger, where it was discovered in November 2023 by a meteorite hunter "in the remote Agadez region of Niger." The government announced that it would open an investigation following the auction to "shed light on the matter."
The incident "very likely has all the characteristics of illicit international trafficking," according to officials in the Nigerien capital, which suspended exports of precious stones and meteorites on Friday, August 8, until further notice. Sotheby's denies the allegations and insists the stone was "exported from Niger and transported in accordance with all applicable international procedures." However, in light of the controversy, a review of the case is underway.
No universal legal status
For American paleontologist Paul Sereno, who has worked closely with authorities in Niamey for years, all evidence suggests the stone left Niger "illegally." "Everyone is anonymous" in this story, he said. It was then sold to an international dealer, briefly exhibited in Italy, and eventually appeared in auction catalogs in the United States.
"If they had caught the meteorite as it was speeding toward Earth and before it landed in a country, then they could have claimed it (...) but in this case, I'm sorry, it belongs to Niger, even if its origin is Mars," he explained. Meteorites do not have a universal legal status; their ownership is governed by international law as well as the specific laws of the country where they land.
Invaluable scientific value
In the United States, for example, ownership of these rocks fallen from the sky goes to the landowner if the property is private, which is not the case in Niger. Niger has a law protecting its cultural heritage, which includes "rare mineralogical specimens," noted Matthieu Gounelle, professor at the Muséum national d'histoire naturelle, and his father, university professor Max Gounelle. Both are specialists in the regulations surrounding the collection and sale of meteorites. According to them, "there is no doubt (...) that meteorites must be included among the rare mineralogical specimens" that are protected.
Beyond the legal disputes and the possible involvement of trafficking networks, the sale of this meteorite also raises ethical questions. This rock, named NWA 16,788, is of inestimable scientific value. Much larger than other known Martian meteorites – which are extremely rare – it offers a unique record of the geological history of the Red Planet.
"In my opinion, this is not something that should be sold at auction and risk disappearing into someone's private collection," argued Professor Sereno, who called for its return to Niger, where it could be studied and displayed to the public.

Google, NASA developing AI tool to treat health problems in space
Google and NASA, the American space agency, are collaborating on an artificial intelligence (AI) tool to address health problems in space, as the United States eyes longer term missions to Mars and the Moon. Called the 'Crew Medical Officer Digital Assistant,' the automated system will help astronauts and their medical crews on Earth to 'diagnose and treat symptoms' in real time during space missions, according to a blog post from Google. The tool will also support flight surgeons, the specialised physicians in space medicine, by giving them data and predictive analytics to aid their decision-making, the post said. The early results for the proof-of-concept project showed 'reliable diagnoses based on reported symptoms,' and the company is now working with doctors to test and refine the model. The AI digital assistant would give detailed diagnoses and treatment options when astronauts have limited contact with their teams on Earth, the company said. That, Google said, 'is becoming increasingly important as NASA missions venture deeper into space'. The work comes as NASA prepares to launch the Artemis II and III missions that will bring humans back to the Moon for the first time since the Apollo program in the 1960s. These Moon missions are part of a roadmap to the United States' first Mars missions, which are planned for the 2030s at the earliest. 'This innovative system isn't just about supporting space exploration; it's about pushing the boundaries of what's possible with AI to provide essential care in the most remote and demanding environments,' Google said. What kind of medical support do astronauts currently get? NASA astronauts receive general medical training in cardiopulmonary resuscitation (CPR), behavioural health, basic first aid, and how to use a medical kit. They also learn about specific space-related illnesses, like the effects of carbon dioxide exposure on the body and decompression sickness. Doctors, psychologists, and flight surgeons are part of an on-ground NASA crew that support the health of astronauts before, during, and after space missions, the agency said. Astronauts can access a 'robust pharmacy' and medical equipment on the International Space Station (ISS) and are able to return to Earth should they need urgent medical care. However, a 2023 study on independent space medical operations published in the IEEE Open Journal of Engineering in Medicine and Biology noted that astronauts on missions outside of low-Earth orbit (LEO), for example those heading to the Moon or Mars, would not have access to real-time medical support due to communication delays. The Moon is outside of LEO, so the researchers predicted that there will be up to a 10-second communication delay and that any emergency evacuations back to Earth could take as long as two weeks. For multi-year missions to Mars, it becomes even more difficult, the study noted. It would take six months to extract an astronaut in a medical emergency and fly them over 500 million kilometres back to Earth. Plus, any urgent communications would face a delay of up to 40 minutes, which means onboard medical support will have to be 'substantially more robust than on ISS,' the study found. For a Mars mission to be successful, the medical system would need to 'make accurate diagnoses and anticipate the questions of specialists on the ground … [to] limit the need for repeated back and forth exchanges,' the authors said.

Tracing a meteorite: Niger outraged over sale of a fragment from Mars
Arriving straight from Mars, a meteorite weighing around 25 kg was sold on July 16 by the auction house Sotheby's to an anonymous private buyer for a record sum exceeding $5 million (about €4.3 million). The sale of the largest Martian meteorite ever found has angered Niger, where it was discovered in November 2023 by a meteorite hunter "in the remote Agadez region of Niger." The government announced that it would open an investigation following the auction to "shed light on the matter."

With 'Alien: Earth,' the creator of 'Fargo' has brilliantly hijacked Ridley Scott's universe
On demand – Series Fame and fortune came to Noah Hawley after he implanted an idea in a foreign body – namely, the Coen brothers' 1996 feature film Fargo, which he used as the template for a series that, since 2014, has brilliantly revisited American anxiety and remorse. It is hardly surprising, then, that this virtuoso practitioner of creative parasitism has turned to the xenomorph that has haunted human nightmares since 1979. Nearly half a century ago, the first incarnation of the Alien creature burst from the chest of Second Officer Kane. This creature who carries the young of her species has served under the direction of Ridley Scott, James Cameron, David Fincher and Jean-Pierre Jeunet. Over the years, she has been by turns a symbol of the hubris that leads humanity to disregard the rest of the universe, the crystallization of corporate greed and the embodiment of an all-consuming femininity. What was Hawley going to do with her? While revealing as little as possible about the tangle of narrative threads and twists that make this first season (six out of eight episodes were previewed) − a structure one never tires of exploring − a word of warning: That same xenomorph, with her grotesquely elongated skull, razor-sharp teeth and corrosive blood, is not at the center of Alien: Earth. The creature will appear, though, since her eggs are aboard the freighter Maginot, chartered by the multinational Weyland-Yutani (as was the Nostromo back in the day), which, at the start of the first episode, is preparing to return to Earth after collecting a few specimens of extraterrestrial wildlife. The name of the spaceship, borrowed from the Maginot Line that failed to stop the German invasion in 1940, will make it clear – at least to French viewers over the age of 90 – that this is, above all, a story about borders and their permeability. Hawley brings his moralistic gaze to questions common to both science fiction and philosophy: humanity's relationship to its environment (which here extends beyond our own planet), the desire for immortality and, as a corollary, the possibility of redefining what it means to be human.
