Largest Mars rock could sell for a staggering $4 million
Mars
, known as NWA 16788, is poised to make headlines as it heads to auction with an estimated price of up to $4 million. Weighing 54 pounds (24.5 kilograms), it is the largest known piece of the Red Planet ever discovered on Earth, making it 70% larger than any previously found Martian meteorite. First unearthed in Niger's remote Agadez region in November 2023, this extraordinary specimen is not only scientifically significant but also visually striking, with a glassy crust and deep red hues that reflect its Martian origin.
Martian Rock: A once-in-a-generation discovery
According to Sotheby's, the auction house hosting the sale on July 16 in New York, NWA 16788 is among just 400 confirmed
Martian meteorites
ever found. Its immense size and exceptional condition set it apart from the usual small fragments that survive Earth's atmosphere. Cassandra Hatton, Vice Chairman of Science and Natural History at Sotheby's, described it as 'a discovery of extraordinary significance... a tangible connection to the Red Planet.' The meteorite likely arrived on Earth after a powerful asteroid impact blasted it from Mars millions of years ago.
Scientific insights encased in glass
Analysis reveals that parts of NWA 16788 were turned to glass during its ejection from Mars and again during its fiery descent through Earth's atmosphere. Planetary scientist Julia Cartwright of the University of Leicester called it a 'fabulous rock,' noting that a reference sample is secured at China's Purple Mountain Observatory, ensuring future scientific study. She emphasized the balance between private collecting and academic access: 'Without the market, we wouldn't have nearly as many samples to study.'
Public or private? Experts weigh in
While some scientists, like Professor Steve Brusatte of the University of Edinburgh, express concern that the rock might vanish into a private vault, others recognize the role collectors play. 'It would be a shame if it disappeared from public view,' said Brusatte. Cartwright, however, remains optimistic, suggesting the new owner could still collaborate with researchers. The meteorite's fate may remain unknown after the auction, but its legacy in planetary science is already secured.

These pictures show India's Shubhanshu Shukla is loving it in space
The Axiom Mission 4 (Ax-4) crew has crossed the halfway mark of their mission aboard the International Space Station (ISS), intensifying efforts to unravel the mysteries of life in microgravity and pave the way for future deep-space Pilot Shubhanshu 'Shux' Shukla is at the forefront of research into how microgravity accelerates muscle atrophy. Latest pictures show how he is enjoying his stay in zero gravity while working on the science sent from performing advanced microscopy and collecting cellular samples for the ongoing myogenesis study, Shux is helping scientists understand why muscle tissue deteriorates so rapidly in space. The Ax-4 crew is also contributing to the Wireless Acoustics project.

Microalgae are being studied for their remarkable potential to support life beyond Earth—they can generate food, oxygen, and even in cultivating microalgae aboard the ISS could make them indispensable for future lunar and Martian outposts, providing sustainable life support and resource recycling.

Elon Musk wants to shut down the International Space Station for which Donald Trump just sanctioned $1.25 billion; says time to focus on ...
The world's richest man and SpaceX CEO Elon Musk has triggered a debate by urging the retirement of the International Space Station (ISS), calling it a relic that's holding back humanity's cosmic ambitions. On July 3, Elon Musk took to Twitter to repost a summary of space-related funding in President Donald Trump's latest tax bill, which allocates $1.25 billion to sustain the ISS through 2030. Musk's blunt response: 'It's time to retire the Space Station and focus on Mars'. Musk's post sparked a heated online debate, with supporters cheering his bold vision and critics defending the ISS as a cornerstone of global scientific collaboration. The ISS, said to be a marvel of engineering orbiting 250 miles above Earth, has been a hub for groundbreaking research since its first module launched in 1998. But at over two decades old, the station is showing its age. NASA has acknowledged that critical systems, including life support and structural components, are nearing the end of their operational life. The tax bill also includes $325 million to fund a safe deorbit process by 2030, signaling that the station's days are numbered. Last year, NASA awarded SpaceX an $843 million contract to build a U.S. Deorbit Vehicle to guide the ISS to a controlled reentry, ensuring it burns up safely over a remote part of the Pacific Ocean. Why Elon Musk wants ISS deorbited Elon Musk argues that the ISS's mounting maintenance costs -- estimated at $3-4 billion annually -- are a drain on resources that could be better spent on humanity's next frontier: Mars. 'The ISS was a great achievement, but it's a 20th-century project,' Musk said in a follow-up post on Twitter. 'If we want to become a multi-planetary species, we need to stop tinkering with old hardware and go all-in on Mars.' His vision for a self-sustaining Martian colony has been a cornerstone of SpaceX's mission since its founding in 2002, with the company's Starship rocket designed to carry crews and cargo to the Red Planet. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Providers are furious: Internet access without a subscription! Techno Mag Learn More Undo What supporters of International Space Station say Critics, however, argue that Musk's push to abandon the ISS overlooks its ongoing contributions. The station hosts experiments in microgravity that have advanced medical research, materials science, and our understanding of long-term space habitation -- knowledge critical for Mars missions. 'The ISS isn't just a lab; it's a symbol of what nations can achieve together,' said Dr. Ellen Stofan, former NASA chief scientist, in a statement to Reuters. 'Dismissing it prematurely risks losing that momentum.' The ISS is a joint effort of the United States, Russia, Europe, Japan, and Canada, and its cooperative framework has weathered geopolitical tensions, including recent strains with Russia over Ukraine. Elon Musk's 'time to retire ISS' divides the internet Public reaction on Twitter too reflect the divide. 'Musk is right—ISS is a money pit. Mars is the future,' posted user @SpacePioneer2030, echoing sentiments from those who see the station as outdated. Others, like @AstroGeek42, countered: 'The ISS still delivers science you can't get anywhere else. Why ditch it before we're ready?' The debate underscores a broader tension in space policy: balancing immediate scientific gains with long-term exploration goals. NASA's current plan keeps the ISS operational until 2030, with private space stations like Axiom Space's proposed orbital habitat expected to fill the gap. But Musk's comments suggest he'd rather see that transition happen sooner. SpaceX, which already ferries astronauts and supplies to the ISS, is positioned to play a key role in both the station's end and the next chapter of space exploration. The company's reusable rockets have slashed launch costs, making ambitious projects like Mars missions more feasible. The tax bill's funding for the ISS and its deorbit underscores a pragmatic reality: the station's end is inevitable. Yet Musk's call to shift focus to Mars raises questions about priorities in an era of constrained budgets and competing global challenges. As one senior NASA official, speaking anonymously, told The Washington Post, 'Elon's not wrong that Mars is the big goal, but the ISS is still teaching us how to get there. It's not an either-or situation—yet."
