NASA's Mars helicopter Ingenuity keeps pushing the aerial exploration envelope.
The 4-lb. (1.8 kilograms) chopper lifted off from the floor of Mars' Jezero Crater today at 10:49 a.m. EDT (1449 GMT), kicking off its fourth flight on the Red Planet.
Ingenuity achieved all of its main technology-demonstrating goals on flights one through three — which occurred on April 19, April 22 and April 25 — so the helicopter's handlers let it off the leash today. Ingenuity covered 872 feet (266 meters) of ground and reached a top speed of 8 mph (13 kph) during the 117-second jaunt, NASA officials said.
