Breakthroughs, discoveries, and DIY tips sent every weekday. You can now own a 1 gold coin celebrating one of America's most revolutionary achievements: the NASA Space Shuttle program. The latest variant in the ongoing American Innovation 1 Coin series is available to order through the United States Mint. Selected to represent the state of Florida, the noncirculating legal tender is the third coin released this year and the 28th coin in the 15-year project first announced in 2018. While the coin's front displays the series' Statue of Liberty image, the back shows the shuttle launching above plumes of exhaust.

It's one of the most profound questions in science – did life ever exist on Mars? Now, experts have unearthed evidence that the Red Planet was once habitable. Scientists have found carbon residue in Martian rocks, indicating that an ancient carbon cycle existed. And it means the Red Planet was likely once warm enough to sustain life. Researchers have long believed that, billions of years ago, Mars had a thick, carbon dioxide-rich atmosphere with liquid water on its surface.

The most accurate clock in space launches within days and will begin building a highly synchronised network out of the best clocks on Earth. But the project, decades in preparation, will only operate for a few years before it burns up as the International Space Station deorbits at the end of the decade. NASA's most accurate atomic clock will be tested on a mission to Venus The Atomic Clock Ensemble in Space (ACES) is a European Space Agency (ESA) mission that will generate a time signal with unprecedented accuracy and then transmit it via laser to nine ground stations as it passes overhead at 27,000 kilometres per hour. This network of clocks will be in extremely close synchronisation and provide highly accurate timekeeping around the world. The result is that ACES will be able to test Einstein's theory of general relativity, which says that the passing of time is affected by the strength of gravity, with great accuracy.

In 2034, the first person landed on Mars. While she didn't go there physically, she still experienced the planet intimately. She explored an ancient river delta and built a base. She put up a flag (China's) and conducted a detailed analysis of rock samples. She achieved all this by inhabiting a robot via a sophisticated brain-computer interface.

From H. G. Wells's The Time Machine to Christopher Nolan's Interstellar, the possibility of travelling through time has fascinated people for centuries. But, although it sounds like pure science fiction, physicists now believe that time travel really is possible. In fact, scientists say that people have already done it. But, before you start to plan your trip to ancient Rome, the experts caution that real time travel is nothing like what you see in the movies. It might seem obvious, but here on Earth, we all move through time at a speed of one second per second.

This paper introduces xRAG, a novel context compression method designed specifically for retrieval-augmented generation.

Tens of millions of miles beyond Earth, a nuclear-powered, car-sized rover is climbing a Martian mountain. NASA's Curiosity rover, while investigating Mars' past, has snapped over 683,790 pictures as it's rumbled over 21 miles of unforgiving desert terrain since 2012, and a recent view shows the space agency's robot overlooking a vast Martian wilderness. Some 3.7 billion years ago, a large object smashed into Mars, leaving the sizeable, 96-mile-wide Gale Crater we see today. When the region's surface rebounded after the powerful collision, it left a central peak, Mount Sharp, which preserves layers of the intriguing, and watery, Mars past. From its perch in the foothills of the 3.4-mile-high mountain, you can see over an expanse of plains, called Aeolis Palus, and beyond that the hilly walls of Gale Crater.

MARGE performs comparably to XLM-R, but with significant variation across languages. We only show results for languages in all model's pre-training data. Languages represent a range of families and geographical regions. The Germanic, Hellenic, Romance, Slavic, and Indo-Iranian families are part of a broader Indo-European family.

After nine months stuck on the International Space Station (ISS), NASA's Butch Wilmore and Suni Williams finally made it back home last night. The duo splashed down off the coast of Florida aboard SpaceX's Crew Dragon capsule, having arrived at the ISS way back in June. While Wilmore and Williams will be relieved to be back on solid ground, their return has ignited a slew of conspiracy theories - with many sceptics critical of the splashdown in particular. Upon arrival, the capsule was circled by an inquisitive pod of dolphins, which many social media commentators are describing as'fake' and computer-generated. Others have taken it even further, suggesting the entire mission footage from departure to landing was created by a sophisticated AI tool.

DOGE leader Elon Musk opens up about his work in space on'Kudlow.' Elon Musk has confirmed that SpaceX's Starship will head to Mars at the end of 2026. The ship will be carrying Optimus, Tesla's humanoid robot. The tech billionaire said that if all goes well, humans could be on the red planet by 2029, although he admitted that 2031 is more likely. NASA's Perseverance Mars rover used its dual-camera Mastcam-Z imager to capture this image of "Santa Cruz," a hill within Jezero Crater, on April 29, 2021, the 68th Martian day, or sol, of the mission. The X account for Optimus replied to Musk's announcement with just two words: "Hold on."
