NASA’s car-size Mars rovers are awesome, versatile machines capable of traversing rugged terrain. But they’re not made to descend down the sides of craters. For that, NASA would need something like its DuAxel prototype rover, a wild concept that is two rovers in one.
When all together, DuAxel is a four-wheeled rover. The rear can anchor itself to the ground while the front goes free on two wheels. A tether holds the pieces together while the front section rappels down a steep slope. This could work well for exploring currently inaccessible crater walls on Mars.

NASA put a DuAxel prototype through its paces in the Mojave Desert in California. “DuAxel performed extremely well in the field, successfully demonstrating its
FOURNÈS, France — On a sultry September morning, Claudie Cortellini headed into the vineyards to survey the grapes that go into her family’s heady Côtes du Rhône wines. In recent years, she has fought to ensure a good harvest as the climate grows warmer. But these days, she is facing an even bigger foe: a giant Amazon sorting center slated for construction near her land.
The project, a concrete-and-steel behemoth that would span nine acres, promises to bring hundreds of jobs to the Gard, an agricultural region in the south of France. Tourists are drawn to the countryside to see a landmark of monumental beauty: the Pont du Gard, a 2,000-year-old Roman aqueduct that rises above the valley like a dusty jewel.
For Mrs. Cortellini and worried residents, however, the jobs are not worth the pollution and explosion in traffic the Amazon warehouse would bring.
Antitrust actions among corporations, particularly those in the tech industry, have received increased attention recently. Many politicians are explicitly calling for the breakup of some of the biggest tech companies out there.
Alphabet is one of many firms targeted by government officials for antitrust scrutiny, even under the administration of supposedly business-friendly President Donald Trump. It is believed that the Justice Department will soon file an antitrust suit against Alphabet related to its dominance in internet search.
Democratic presidential nominee Joe Biden has stopped short of saying he would break up any company over alleged antitrust actions. Nonetheless, Biden has called for more stringent antitrust scrutiny. The possibility of such actions fuels speculation over expanded antitrust investigations.

The power of the sun, wind and sea may soon combine to produce clean-burning hydrogen fuel, according to a team of Penn State researchers. The team integrated water purification technology into a new proof-of-concept design for a sea water electrolyzer, which uses an electric current to split apart the hydrogen and oxygen in water molecules.
This new method for “sea water splitting” could make it easier to turn wind and solar energy into a storable and portable fuel, according to Bruce Logan, Kappe Professor of Environmental Engineering and Evan Pugh University Professor.
“Hydrogen is a great fuel, but you have to make it,” Logan said. “The only sustainable way to do that is to use renewable energy and produce it from water. You also need to use water that people do not want to use for other things, and that would be sea water. So, the holy grail of producing
A solar-powered automatic drone charger is seen in the Zhangjiang artificial intelligence (AI) island in Shanghai on Tuesday. The Zhangjiang AI island, covering 100,000 square meters, is expected to be a cluster of AI companies, projects and talent with Microsoft and IBM as the two major participants, media reports said. The island will focus on high-technology sectors like big data, cloud computing and blockchain. Photo: IC
Shanghai’s Pudong New Area, the wealthiest district in China with a per capita GDP of $33,200, higher than that of South Korea, is well on course to lead the nation’s high-tech push, especially in artificial intelligence (AI), with the developer and operator of a smart AI facility revealing plans on Tuesday to generate taxes of 10 billion yuan ($1.47 billion) per annum by 2025.
The local AI ambition, as part of a national effort to win the global AI race, is considered of pivotal
