NASA helicopter Ingenuity completed its third flight on Mars today, moving farther and faster than before, with a peak speed of two metres per second, reports phys.org. The helicopter covered 50 metres. “Today’s flight was what we planned for, and yet it was nothing short of amazing,” said Dave Lavery, the Ingenuity project’s program executive. Video clips will be sent to Earth in the coming days. Ingenuity’s flights are challenging because of conditions vastly different from Earth’s – foremost among them a rarefied atmosphere that has less than one per cent the density of our own.
