Scientists with the U.S. space agency NASA Friday said the tiny helicopter they sent to Mars has exceeded their expectations, despite a glitch that forced its fourth flight to be rescheduled.   During a virtual news briefing on the Mars mission, scientists and engineers with NASA’s Jet Propulsion Laboratory said the Ingenuity helicopter’s first three flights showed them enough capability that they are expanding the operation of the aircraft by 30 days, doubling its originally planned mission time.   NASA had originally described the Ingenuity project as a technology demonstration …

The U.S. space agency NASA said the experimental Mars helicopter Ingenuity, after three successful flights, failed to respond to commands to lift off for a fourth flight Thursday. Scientists with the Ingenuity team at NASA’s Jet Propulsion Laboratory (JPL) in southern California say a software problem similar to one that delayed the experimental craft’s initial flight 11 days ago prevented the helicopter from transitioning to “flight mode.” The scientists plan to try again Friday. The 1.8-kilogram aircraft arrived on the planet packed away on NASA’s Perseverance rover when it landed …

A study published Wednesday shows nearly all the world’s glaciers have been melting at an accelerated pace in recent years, accounting for rises in sea level over the last two decades.In the study, published in the science journal Nature, an international group of scientists used high resolution imagery from NASA’s Terra satellite to study 220,000 of the world’s glaciers between 2000 and 2019.They found those glaciers lost an average of 267 billion tons – 267 gigatons – of ice per year.The study found melting increased over time, from an average …
