NASA Captures Mars Volcano Twice The Height Of Earth's Tallest Peaks
The panorama image taken on May 2, using the Thermal Emission Imaging System (THEMIS), shows the planet's massive volcano for the first time. Arsia Mons is the southernmost of the Tharsis volcanoes and cloudiest of the three.
'We picked Arsia Mons hoping we would see the summit poke above the early morning clouds. And it didn't disappoint,' said Jonathon Hill of Arizona State University in Tempe, operations lead for THEMIS.
Researchers said the clouds are especially thick over Arsia Mons when the Red Planet is farthest from the sun, a period called aphelion.
"Understanding Mars' clouds is particularly important for understanding Martian weather and how phenomena like dust storms occur," NASA stated.

The Odyssey orbiter was launched in 2001 and is regarded as the longest-running mission orbiting another planet. To click the picture, the orbiter rotates 90 degrees while in orbit so that its camera, built to study the Martian surface, can capture it cleanly.
The angle of the camera allows scientists to see dust and water ice cloud layers, enabling them to observe changes over the course of seasons.
'We're seeing some really significant seasonal differences in these horizon images,' said planetary scientist Michael D. Smith of NASA's Goddard Space Flight Center in Greenbelt, Maryland. 'It's giving us new clues to how Mars' atmosphere evolves over time.'

Shukla In space: Benefits far outweigh cost, says Isro chief

The Rs 548 crore spent on the mission is a fraction of what India would have otherwise needed to spend on replicating the same training, exposure and systems-level experience, Isro chairman V Narayanan told TOI, in his first exclusive interview about the multinational commercial mission. Speaking from Houston, Narayanan said that the learning outcomes — spanning astronaut training (for two astronauts), mission operations, and hardware-software-human interface — cannot be measured purely in monetary terms. 'For a country of 140 crore people, what we've spent is only marginal,,' Narayanan said. For that, he said: 'We've gained access to infrastructure and experience that would otherwise require thousands of crores.' If one looks at the per capita cost on the Indian population, it adds up to around Rs 4 per head. Look Beyond Rupee Figure Narayanan, dismissing observations that Ax-4 is 'just a commercial mission', said discussions on such strategic missions must be rooted in long-term capability building rather than short-term financial arithmetic. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Morocco: New Container Houses (Prices May Surprise You) Container House | Search ads Search Now Undo 'For a programme like Gaganyaan , which spans Rs 20,000 crore including follow-on missions, these early investments are necessary. Training, confidence, exposure, systems understanding — these are foundational,' he said. He added that maturity in public discourse is essential. 'People must recognise that not all benefits can be quantified. But they can certainly be measured in preparedness and capability,' he said. Five Takeaways Narayanan identified five key areas where Ax-4 will directly strengthen India's human spaceflight capabilities: Training exposure, confidence building, operational experience, systems-and-process understanding, and cross-disciplinary learning. 'Our astronauts trained in world-class facilities simulating space conditions, including microgravity and life-support systems. Each hour of training they've undergone would cost crores if we were to replicate the infrastructure ourselves,' he said. He added that interacting with seasoned astronauts — including those who have flown to space multiple times or performed several spacewalks — helped boost the confidence of Indian crew members and mission teams. Astronauts — Shux and his backup Group Captain Prashant Nair — learnt how to function in space as a team, handle real-time challenges, and carry out experiments. He said working on and observing the mission to ISS has given India insights into module design, layout, onboard systems, and processes that will feed into future Gaganyaan and space station designs. 'We will, of course, have our own design and technology, but all this experience will help us develop those better,' he said. Isro Engineers Narayanan, who is leading efforts to ensure astronaut safety, said he has himself gained from observing operations in Houston. 'From data handling to high-level system safety discussions, our understanding of the end-to-end process has grown. This cannot be acquired by simulation or literature review alone,' he said. He added that the experience is equally valuable for backroom mission teams and decision-makers, who will now have real-world references to draw upon while preparing for Gaganyaan. TOI had reported last week about some specifics the Isro team is learning back in Houston, where mission control for Ax-4 is. Space Station India plans to build its own space station after the Gaganyaan crewed flights. Narayanan said direct exposure to the ISS environment will inform the design, configuration, and operational planning of the proposed Indian facility. 'We had only studied the ISS on paper. Now we are seeing it in action. We may not adopt the same model, but this will help us make informed design choices,' he said.

Anil Menon: Who Is NASA Astronaut Whose Wife Went On Private Spacewalk Mission In 2024?
Last Updated: NASA said it is sending Anil Menon for his first mission to the International Space Station as a flight engineer and Expedition 75 crew member in June 2026 Selected to be an astronaut in 2021, Anil Menon will make his first trip to space as a flight engineer and Expedition 75 crew member in June 2026. NASA said it is sending Menon for his first mission to the International Space Station next year, and he will be launching aboard the Roscosmos Soyuz MS-29 spacecraft with cosmonauts Pyotr Dubrov and Anna Kikina. The premier space agency said after launching from the Baikonur Cosmodrome in Kazakhstan, the trio will spend approximately eight months aboard the orbiting laboratory. Anil Menon, who is a NASA Artemis astronaut candidate graduate, will conduct scientific investigations and technology demonstrations to help prepare humans for future space missions. Fun fact: his wife Anna Menon, who worked for NASA before joining SpaceX, went for a private spacewalk mission last year. She is a lead space operations engineer at Elon Musk's company and has written a children's book about space titled Kisses from Space. Like his wife, he has also worked for SpaceX, serving as the first flight surgeon while helping to launch the first crewed Dragon spacecraft on NASA's SpaceX Demo-2 mission and building SpaceX's medical organisation to support humans on future missions. He served as a crew flight surgeon for both SpaceX flights and NASA expeditions aboard the space station. Menon graduated with the 23rd astronaut class in 2024. He began preparing for his first space station flight assignment after completing initial astronaut candidate training. He still practises emergency medicine at Memorial Hermann's Texas Medical Center and teaches residents at the University of Texas residency programme in his spare time. First Published:

Major reports about how climate change affects the US are removed from websites
WASHINGTON: Legally mandated US national climate assessments seem to have disappeared from the federal websites built to display them, making it harder for state and local governments and the public to learn what to expect in their backyards from a warming world. Scientists said the peer-reviewed authoritative reports save money and lives. Websites for the national assessments and the US Global Change Research Program were down Monday and Tuesday with no links, notes or referrals elsewhere. The White House, which was responsible for the assessments, said the information will be housed within NASA to comply with the law, but gave no further details. Searches for the assessments on NASA websites did not turn them up. NASA did not respond to requests for information. The National Oceanic and Atmospheric Administration, which coordinated the information in the assessments, did not respond to repeated inquiries. "It's critical for decision makers across the country to know what the science in the National Climate Assessment is. That is the most reliable and well-reviewed source of information about climate that exists for the United States," said University of Arizona climate scientist Kathy Jacobs, who coordinated the 2014 version of the report. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Glicemia acima de 100? Insira essa fruta na sua dieta Saúde Nacional Undo "It's a sad day for the United States if it is true that the National Climate Assessment is no longer available," Jacobs said. "This is evidence of serious tampering with the facts and with people's access to information, and it actually may increase the risk of people being harmed by climate-related impacts." Harvard climate scientist John Holdren, who was President Obama's science advisor and whose office directed the assessments, said after the 2014 edition he visited governors, mayors and other local officials who told him how useful the 841-page report was. It helped them decide whether to raise roads, build seawalls and even move hospital generators from basements to roofs, he said. "This is a government resource paid for by the taxpayer to provide the information that really is the primary source of information for any city, state or federal agency who's trying to prepare for the impacts of a changing climate," said Texas Tech climate scientist Katharine Hayhoe, who has been a volunteer author for several editions of the report. Copies of past reports are still squirreled away in NOAA's library. NASA's open science data repository includes dead links to the assessment site. The most recent report, issued in 2023, included an interactive atlas that zoomed down to the county level. It found that climate change is affecting people's security, health and livelihoods in every corner of the country in different ways, with minority and Native American communities often disproportionately at risk. The 1990 Global Change Research Act requires a national climate assessment every four years and directs the president to establish an interagency United States Global Change Research Program. In the spring, the Trump administration told the volunteer authors of the next climate assessment that their services weren't needed and ended the contract with the private firm that helps coordinate the website and report. Additionally, NOAA's main website was recently forwarded to a different NOAA website. Social media and blogs at NOAA and NASA about climate impacts for the general public were cut or eliminated. "It's part of a horrifying big picture," Holdren said. "It's just an appalling whole demolition of science infrastructure." The national assessments are more useful than international climate reports put out by the United Nations every seven or so years because they are more localized and more detailed, Hayhoe and Jacobs said. The national reports are not only peer reviewed by other scientists, but examined for accuracy by the National Academy of Sciences, federal agencies, the staff and the public. Hiding the reports would be censoring science, Jacobs said. And it's dangerous for the country, Hayhoe said, comparing it to steering a car on a curving road by only looking through the rearview mirror: "And now, more than ever, we need to be looking ahead to do everything it takes to make it around that curve safely. It's like our windshield's being painted over."
