Largest piece of Mars on Earth sells for $5.3 million
By Dean Murray The largest piece of Mars on Earth has sold for $5.3m. Meteorite NWA 16788, offered by Sotheby's New York on Wednesday, July 16, instantly set a new world record as the most valuable meteorite ever sold at auction. Discovered on Nov. 16, 2023, by a meteorite hunter in Niger's remote Agadez region and weighing 54 pounds (24.67 kg), the specimen is approximately 70% larger than any other Martian fragment known today. Featuring an unmistakable Martian red hue, NWA 16788's internal composition suggests it was blasted from the surface of the Red Planet by a powerful asteroid impact-an event so intense that it turned some of the meteorite's minerals into glass. Areas of glassy fusion crust also appear on the meteorite's surface, evidence of its rapid and violent descent through Earth's atmosphere to its eventual landing place in the Sahara Desert.

‘Mission: Impossible' IRL? Device self-destructs at push of a button
By Dean Murray A "Mission: Impossible"-style data storage device self-destructs at the push of a button. The newly-launched tech is able to delete all files contained on it, even when power is lost. It works in a similar fashion to the "Mission: Impossible" film series, where secret agent Ethan Hunt, played by Tom Cruise, listens to recorded instructions that end with "This message will self-destruct in five seconds." In the movies, the message is followed by a dramatic countdown and the playback device then destroys itself in a small burst of smoke or flames to preserve secrecy. Taiwanese firm Team Group says their P250Q SSD has a hardware destruction process that takes about 10 seconds, after which the stored data is totally unrecoverable. As well as a software wipe option, an irreversible physical hardware destruction mode sends a powerful surge of electricity directly to the SSD's NAND flash memory chips. The resulting electrical "blast" rapidly fries the memory cells, physically damaging the chips so that data cannot be recovered, even with advanced forensic tools. Designed with real-world deployment in mind, the P250Q combines dual-mode software-hardware destruction, a one-click activation button, and multi-stage LED indicators that display real-time progress. Available in storage sizes up to 2TB, the company says the product is engineered to meet the stringent security and stability requirements of military, industrial automation, and AI applications, and sets a new benchmark for data protection. Team Group said: "Moving forward, Team Group will continue to place innovation at the core of its values, delivering safer and more intelligent storage solutions tailored for global industrial and military-grade applications."

US unveils city-destroying nuclear missile after years of secrecy
By Dean Murray The United States has unveiled its city-destroying nuclear cruise missile after years of secret development. The first image of the AGM-181A Long-Range Standoff (LRSO) reveals a sleek, stealthy weapon designed to evade modern air defenses, with a range said to exceed 1,500 miles. It is thought the missile will have an adjustable nuclear yield between 5–150 kilotons, allowing uses ranging from tactical effect to destroying cities. A yield of 150 kilotons is 10 times more powerful than the bomb dropped on Hiroshima in August 1945. The LRSO is set to replace the Cold War-era AGM-86B and will be carried by both the forthcoming $585m B-21 Raider and upgraded B-52 bombers. Air Force officials confirmed that the LRSO has already undergone a series of successful flight tests is set for frontline service by 2030.

How NASA plans to mine the Moon
By Dean Murray The United States has shown off how it plans to mine the Moon. Incredible scenes show NASA testing a vehicle designed to extract vital resources that could help humans live in the lunar environment or even on Mars. Engineers at Kennedy Space Center in Florida are experimenting with the RASSOR (Regolith Advanced Surface Systems Operations Robot) on a simulated lunar surface. RASSOR's counter-rotating drums dig up simulated moon dust to extract regolith, the loose, fragmental material found on the Moon's surface. The opposing motion of the drums helps RASSOR grip the surface in low-gravity environments like the Moon or Mars. On Tuesday (June 3), NASA said: "With this unique capability, RASSOR can traverse the rough surface to dig, load, haul, and dump regolith that could later be broken down into hydrogen, oxygen, or water-resources critical for sustaining human presence." The space agency is using the foundation of RASSOR's development to inform IPEx (In-Situ Resource Utilisation Pilot Excavator), a newer vehicle being prepared for a potential technology demonstration mission on the Moon. IPEx is still in the advanced development and testing phase and will improve on RASSOR with refinements in scale, modularity, and mission capability to support future lunar resource extraction missions.
