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.

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.
