All you need to know about the Brazilian woman NASA fact-checked over viral mars and moon mission claims
A viral Instagram post by Brazilian influencer Laysa Peixoto claiming she had been selected as a "career astronaut" for future Moon and Mars missions has drawn sharp criticism—and an official denial—from NASA. On June 5, Peixoto shared a photo of herself in NASA-branded attire with the New York City skyline in the background, declaring she was part of the astronaut class of 2025 and had completed astronaut training in 2022. She also claimed she was joining a 2029 spaceflight led by former
NASA
astronaut Bill McArthur through private firm Titan Space.
The post garnered over 83,000 likes and positioned her as Brazil's first female astronaut, but NASA quickly discredited her claims. In a public statement, the agency clarified that Peixoto is 'not a NASA employee, principal investigator, or astronaut candidate,' and that her only involvement was a student workshop, not formal employment or training. 'It would be inappropriate to claim NASA affiliation,' the agency added.
Further questions arose around Peixoto's academic credentials. The Federal University of Minas Gerais confirmed she was dismissed in 2023, while Columbia University denied she had ever enrolled, contradicting her claim of pursuing a master's in quantum computing. Her since-deleted LinkedIn also listed unverifiable affiliations with NASA, MIT, and Germany's Max Planck Society.

Titan Space initially acknowledged her but later clarified she is not listed among the astronauts for its planned 2029 mission. The company, which lacks FAA approval for human spaceflight, offers commercial flights for a fee or by invitation. Their official press release did not include Peixoto's name, and no further details of her involvement have been made public.
Following the backlash, Peixoto's team released a statement insisting she never claimed NASA selected her, but evidence later showed her Instagram post had been edited. Her case serves as a cautionary tale about self-promotion in the age of social media, where inflated claims can quickly collide with institutional standards and public accountability.

After delay, India's Shubhanshu Shukla's Axiom-4 mission to launch on June 19: Isro
The muchdelayed Axiom4 commercial mission to the International Space Station, carrying Indian astronaut Shubhanshu Shukla and three others, is now targeting a launch on June 19, the Indian Space Research Organisation (ISRO) announced on Saturday. read more Axiom Mission 4 crew, from left to right, ESA (European Space Agency) astronaut Slawosz Uznanski-Wisniewski of Poland, former NASA astronaut Peggy Whitson, ISRO (Indian Space Research Organization) astronaut Shubhanshu Shukla, and Tibor Kapu of Hungary. Image Courtesy: NASASpaceOps via PTI Photo The much-delayed Axiom-4 commercial mission to the International Space Station, carrying Indian astronaut Shubhanshu Shukla and three others, is now targeting a launch on June 19, the Indian Space Research Organisation (ISRO) announced on Saturday. The Axiom Space mission was to blast off from NASA's Kennedy Space Centre in Florida on June 11, but had to be delayed first due to a fuel leak in SpaceX's Falcon-9 rocket and then due to a leak in the Russian section of the International Space Station (ISS). STORY CONTINUES BELOW THIS AD 'During a follow-on coordination meeting between ISRO, Axiom Space, and SpaceX, it was confirmed that the liquid oxygen leak observed in the Falcon 9 launch vehicle has been successfully resolved,' the ISRO said in a statement. 'Separately, Axiom Space informed that they are working closely with NASA to assess the pressure anomaly in the Zvezda Service Module on board the International Space Station,' it said. 'Axiom Space is now targeting June 19, 2025, for the launch of the Ax-04 mission,' ISRO said. The astronauts were originally scheduled for lift-off on May 29, which was put off to June 8, June 10 and June 11, when SpaceX, the providers of the launch rocket and the space capsule, detected a liquid oxygen leak in the Falcon-9 rocket. Former NASA astronaut and director of human spaceflight at Axiom Space, Peggy Whitson, will command the commercial mission, while ISRO astronaut Shubhanshu Shukla will serve as the pilot. The two mission specialists are European Space Agency (ESA) project astronaut Slawosz Uznanski-Wisniewski of Poland and Tibor Kapu of Hungary. The 14-day mission will 'realise the return' to human spaceflight for India, Poland and Hungary.

Startups show off ocean-preserving tech at Paris trade fair
Harnessing ocean currents to boost fuel efficiency of vessels, or tracking whales using sensor data and AI -- startups at Paris trade fair Vivatech have been showing off the latest innovations aimed at protecting the environment. Recently developed AI programs capable of learning from vast datasets have boosted projects trying to understand and predict real-world phenomena, several company founders told AFP. "We have to use AI because in the natural world there are too many variables" to deal with manually, said Emily Charry Tissier, a biologist and founder of Canadian startup Whale Seeker, which is developing technology to track sea mammals. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Access all TV channels anywhere, anytime Techno Mag Learn More Undo Powered by "neural network" systems that ape the functioning of the human brain, the learning systems behind today's AI models "can calculate a weather forecast 1,000 times faster than a standard digital model running on a supercomputer", agreed oceanographer Alexandre Stegner. He flagged an AI model developed by his firm, Amphitrite, that he said could predict ocean currents by crunching "several layers of satellite data corresponding to different physical variables". Live Events It can forecast currents up to 10 days in advance, he said, offering sea captains "a simple way to save fuel" by slightly changing course and using currents to gain a speed boost of up to four knots. Discover the stories of your interest Blockchain 5 Stories Cyber-safety 7 Stories Fintech 9 Stories E-comm 9 Stories ML 8 Stories Edtech 6 Stories That could save operators money on fuel, reduce the carbon emissions from shipping, and avoid the classic solution of telling sea captains to reduce their speed. Global protection push Technologies like these were being shown off in the halls of Vivatech as the UN Ocean Conference (UNOC) drew to a close hundreds of kilometres to the south in French Mediterranean city Nice. The conference has pushed a treaty to protect 60% of the world's oceans closer to becoming law, with 55 signatures -- just five shy of the number required for its enactment. New technologies could be "a very good thing" for the oceans, said Andre Abreu, International Affairs Director at the Paris-based Tara Ocean Foundation. But he warned that innovation should not be harnessed to allow more fish to be caught. "That would mean shooting ourselves in the foot" on goals like preserving marine biodiversity, he said. That ambiguity can be seen in technology from OceanEyes, a Japanese startup using AI analysis of satellite data to predict sea conditions. The company hopes to cut the time fishing boats spend tracking down a catch. "A big problem in Japan is the efficiency of the fishery operations. Many fishers spend a lot of time searching for fish in the water," said boss Yusuke Tanaka. With less fuel burnt, operators will save money and greenhouse emissions can be slashed. Anticipating concerns about overfishing, OceanEyes said it also aimed to help vessels comply with recently updated Japanese regulations that oblige fishers to "ensure sustainable use of marine resources". 'Can' vs 'should' Whale Seeker's Tissier said technology could be used in a considered way to find sustainable solutions. "I'd like the market to recognise its own limits -- not the limits of what we can do, but what we should do," she told AFP. That attitude pushed her to refuse to work with a company that wanted to use whale detection to identify nearby fish to catch. But startups cannot grow without funding and, in the context of oceans, investments are likely to come from big firms keen to make a saving -- from fishing and ship management companies to haulage and logistics giants. This could well limit their ability to stand on principle. Stegner called for "regulations that would push the maritime sector to reduce carbon emissions". But Charry Tissier said the initiative could come from business. "Technology is developing so much faster than regulation... what I'd like is for big companies to decide for themselves to be responsible," she said.
