Ingenuity Mars Helicopter Went Silent, Leaving Anxious NASA Team in the Dark

Ingenuity Mars Helicopter Went Silent, Leaving Anxious NASA Team in the Dark

Late last week, NASA’s Ingenuity helicopter managed to reestablish its connection with the Perseverance rover following a brief communications disruption. The space agency says the looming winter is likely responsible and is making adjustments as a result. On Thursday, Ingenuity—mercifully—sent a signal to Perseverance after the intrepid helicopter missed a scheduled communications session. It marked …

Huge Groundwater System Discovered Under Antarctica

The research team collected data in blistering cold of Antarctica for weeks to map the continent’s subsurface.Photo: Kerry Key Antarctica, far from just a sprawling mass of ice, is a geologically complex continent made of expansive glaciers, jagged bedrock, and, as new research finds, large amounts of groundwater. HAS study published today in the journal …

Fossils of Giant Dolphin-Like Marine Reptiles Found in Swiss Alps

A paleontologist excavating in the Swiss Alps in 1976.Photo: Heinz Furrer A team of paleontologists has discovered fossils of three impressive new ichthyosaurs—ancient marine reptiles—in rocks located 9,000 feet above sea level. The ichthyosaurs were found in excavations that took place between 1976 and 1990, but the remains were very fragmentary. Since then, more comparative …

Here’s How Martian Explorers Could Best Produce Electricity on the Red Planet

Artistic conception of a crewed mission to Mars. Picture: NASA Scientists are on the fence as to whether solar or nuclear should be the preferred source of power for small teams visiting the Martian surface. New research suggests both options are good, with geographical location being the determining factor. Tea researchers compared two different power-generating …

PFAS ‘Forever Chemicals’ Might Be Hurting Our Livers, Study Finds

PFAS chemicals end up in our environment through the plastic products and other trash we throw out. Picture: Zakir Hossain Chowdhury/NurPhoto (Getty Images) New research finds evidence that per- and polyfluoroalkyl substances, known as PFAS, can damage people’s lives over time. The study, a review of the evidence in both rodents and humans, might also …
