New York to auction largest known piece of Mars on Earth
Named NWA 16788, this meteorite is believed to have been blasted off Mars by a colossal asteroid impact, hurtled 140 million miles through space, and finally landed in the Sahara Desert. It was discovered by a meteorite hunter in Niger in November 2023, reported AP citing Sotheby's.
'This Martian meteorite is the largest piece of Mars we have ever found by a long shot,' said Cassandra Hatton, vice chairman for science and natural history at Sotheby's. 'So it's more than double the size of what we previously thought was the largest piece of Mars.'
Measuring nearly 15 inches by 11 inches by 6 inches, this red, brown, and grey chunk is around 70% larger than the second-biggest known Martian meteorite. It alone accounts for nearly 7% of all Martian material ever found on Earth.
Sotheby's notes, as per AP, that there are only about 400 confirmed Martian meteorites among the 77,000+ meteorites officially recognised on Earth.
To confirm its extraterrestrial origin, a small piece was sent to a specialist lab and compared with the chemical fingerprint established by NASA's Viking probe, which landed on Mars in 1976. The results were conclusive: the rock is an olivine-microgabbroic shergottite, a slowly cooled Martian magma type filled with pyroxene and olivine crystals.
Its glassy surface hints at the fiery entry it endured while hurtling through Earth's atmosphere.
Expected to fetch between $2 million and $4 million, this meteorite leads a collection of 122 items in Sotheby's Geek Week 2025 natural history-themed sale.
The lot also includes a juvenile Ceratosaurus nasicornis skeleton, a dinosaur measuring over 6 feet tall and nearly 11 feet long. As for the Mars rock, its journey may have spanned millions of years and millions of miles, but its final stop may be a collector's cabinet, unless a museum or research institution steps wins the bid.

What Shubhanshu Shukla's Axiom 4 mission will mean for India's space ambitions
'The second Indian in space', Group Captain Shubhanshu Shukla's return journey to terra firma was safely and successfully accomplished on July 15. Shukla is back after a fruitful stay of about 18 days on the International Space Station (ISS). A day before his return, the Crew Dragon spacecraft 'Grace' in which he comfortably sat with his three Axiom 4 colleagues successfully undocked (detached) from the ISS, circling the earth at 400 km height. For the next 22 hours or so, the craft independently orbited the Earth and then dived back into the atmosphere, survived the subsequent fiery re-entry heat and splashed down off the coast of California at a comfortable speed of about 24 km per hour. With this, Shubhanshu Shukla's maiden sojourn in space concluded. Understandably, the successful completion of Shukla's Axiom 4 mission will make the already joyous India more euphoric for quite some time. People across the country, especially students, will be eagerly awaiting Shukla's return. Many among our hundreds of millions of strong, intelligent and capable students will consider Shukla as a role model. Shukla has said that India's first space traveller, Rakesh Sharma, was a role model. The sense of excitement associated with spaceflight, especially human spaceflight, and the inspiration it can provide, is immense. It can effectively empower students to pursue STEM education with seriousness. This is one of the prominent benefits to accrue from Shukla's exciting and worthwhile journey to space. Having many significant achievements to its credit in the arena of uncrewed spaceflight, India is confidently and cautiously taking its first step into human spaceflight. Gaganyaan aims to launch Indian space travellers ('gaganyatris') from Indian soil, in an Indian-built spacecraft, propelled by an Indian launch vehicle, make them orbit the earth for a few days and bring them back safely. Serious and systematic efforts are being led by ISRO, with the enthusiastic participation of many national scientific/technological institutions of repute. As part of this arduous endeavour, the human rating (significantly enhancing the reliability of a rocket vehicle to safely launch human beings) of India's most capable launch vehicle, HLVM3, is reportedly completed. The design and development of the Gaganyaan spacecraft, which will be capable of accommodating three space travellers, is in progress. Prashanth Balakrishnan Nair, Ajit Krishnan, Angad Pratap and Shubhanshu Shukla, all test pilots now holding the rank of group captain in the Indian Air Force, have been selected and trained in India and Russia. The participation of one of its astronaut candidates in Axiom 4 will enrich Gaganyaan in terms of planning and execution. In this regard, it is pertinent to remember that Shubhanshu Shukla was extensively trained in many US facilities, including at NASA, for about eight months. Fairly detailed knowledge of such facilities as well as the training procedures would not have been available to us without the participation in a human spaceflight mission. Thus, not only the experience of getting trained for the launch, but the first-hand experience of travelling in a spacecraft to Earth orbit has been acquired by Shukla. More importantly, he has gained invaluable experience of living and working in the weightless environment of space aboard the ISS. That he was able to perform the carefully designed and packaged bio-medical, healthcare, space food production and cognitive science-related experiments from India, has greatly encouraged our scientific and engineering community and enhanced our confidence and atmanirbharata. Thus, India's participation in the Axiom 4 mission is beneficial in many ways indeed.

Shubhanshu Shukla return: Here's how much ISRO spent & what Shubhanshu Shukla was paid for Ax-4 mission
Shubhanshu Shukla return: Indian astronaut Shubhanshu Shukla recently created history by becoming the first Indian ever to live and work on the International Space Station (ISS). Part of the Ax-4 mission, Shukla's journey marks a proud moment not just for him but also for India's growing space ambitions. Let's take a closer look at how much ISRO spent on this mission and whether Shubhanshu Shukla was paid any salary during his stay in space. Shubhanshu Shukla's Historic Journey to the ISS On July 15, 2025, Shubhanshu Shukla, along with Commander Peggy Whitson, Polish astronaut Slawosz Uznanski, and Hungarian crewmate Tibor Kapu the crew of the Axiom Mission 4 (Ax-4), returned to Earth after spending 18 days aboard the ISS. Originally planned for 14 days, the mission was extended due to scientific requirements and scheduling. • 20 days, 3 hours in space• 322 orbits completed• 1,39,10,400 kilometres travelled• 1st ever Indian on ISSWelcome back to Earth Gp Capt Shubhanshu Shukla 🌏🇮🇳 By completing this journey, Shukla became the first Indian astronaut to stay on the ISS and only the second Indian ever to travel to space, the first was Rakesh Sharma, who flew aboard a Soviet spacecraft in 1984. Did Shubhanshu Shukla Receive a Salary for the Ax-4 Mission? Here's the surprising part - Group Captain Shubhanshu Shukla, a distinguished pilot in the Indian Air Force (IAF), has 2,000 hours of flight experience across various aircraft, but was not paid any salary for the Ax-4 mission, as per CNBC TV 18. Even though he spent nearly three weeks in space, Shukla did not receive direct payment from ISRO, NASA, or Axiom Space. That said, this mission wasn't about financial reward but rather about gaining experience and contributing to India's growing space research and future human spaceflight programmes. ISRO Spent Rs 548 Crore on Shukla's Space Mission While Shubhanshu Shukla didn't earn a salary, the Indian Space Research Organisation (ISRO) fully sponsored India's part in the mission. According to a report by BBC, ISRO spent around Rs 548 crore on training, logistics, and scientific research for Shukla's spaceflight. This massive budget covered several critical aspects: Specialised astronaut training provided by NASA and Axiom Space Launch and return logistics Travel and accommodation on the International Space Station Support for scientific experiments carried out in microgravity Axiom Space and NASA Collaborated with ISRO The Ax-4 mission was a private space venture by Axiom Space, conducted in collaboration with NASA. Though international in nature, India's involvement was made possible only because ISRO covered all expenses related to Shukla's participation. As a result, he was not on the payroll of NASA or Axiom. This strategic investment by the Indian government is expected to pay off in the form of experience, exposure, and scientific advancement. Scientific Experiments Led by Shubhanshu Shukla in Space During his time aboard the ISS, Shubhanshu Shukla conducted seven key scientific experiments designed by ISRO. These were part of a larger group of 60 experiments carried out by the Ax-4 crew. His experiments included: Impact of microgravity and radiation on edible microalgae Sprouting salad seeds in space Survival and gene expression in eutardigrade paramacrobiotus (BLR strain) Effect of metabolic supplements on muscle regeneration Human interaction with electronic displays in microgravity Comparative growth of cyanobacteria on urea and nitrate Microgravity effects on growth and yield of food crop seeds These experiments will play a important role in developing technologies for India's future space missions, including Gaganyaan and other long-duration space travel. Shubhanshu Shukla's Future in ISRO and Gaganyaan Mission Even though Shubhanshu Shukla did not receive a salary for the Ax-4 mission, his experience is invaluable. The knowledge and skills he gained will be crucial for ISRO's Gaganyaan mission, India's first manned space mission planned for 2027. Shukla is now expected to take on a significant role in India's human spaceflight programme, and his journey is being seen as a stepping stone for India's future space leadership. Shubhanshu Shukla made history not for monetary gain but for pushing the boundaries of India's space achievements. Though he received no salary for his time in orbit, ISRO's Rs 548 crore investment is a bold move that reinforces India's commitment to space exploration. With the successful completion of the Ax-4 mission, India is now one step closer to achieving its long-term goal of sending astronauts to space through its own Gaganyaan programme.
