NASA to send a helicopter to Mars

Not content material with rovers, NASA’s subsequent Mars mission will embrace a helicopter that would be the first human craft to fly round one other planet and will probably pave the best way for groundbreaking exploration on Mars and past.

The Mars 2020 Rover will land on the Red Planet in early 2021 with a small helicopter on board, to take a look at if it will likely be ready to fly. Until now, the one man-made objects which have visited Mars are rovers, orbiters and landers.

The helicopter mission will final 30 days and can consist of 5 flights, a few of which is able to merely be hovering assessments, simply 10 ft off the bottom.

Should the primary mission achieve success, it may open up a complete new world of potential for planetary exploration. Currently, robotic explorers have been restricted to the purple planet’s floor, and might’t get to each nook and cranny.

“We envision helicopters opening doors to new types of exploration on Mars,” Håvard Grip, flight-control and aerodynamics lead for the Mars Helicopter said“In the future, we could imagine doing things like regional exploration using multiple helicopters or going to inaccessible areas or biologically sensitive areas using small helicopters.”

Mars has a far thinner environment than Earth, which means that flying simply above the floor is the equal of being at 100,000 ft in Earth’s environment. Helicopters normally fly at a max of 10,000 ft.

NASA’s Jet Propulsion Laboratory created an especially gentle chopper, weighing simply 4 kilos, with blades that can spin at 3,000 rpm, 10 instances sooner than most abnormal helicopters. It was authorized for the Mars mission in May and shall be fitted with solar energy batteries, and a heater.

It isn’t simply the skinny environment that presents a problem for the chopper, although: the space between Earth and Mars means there can be a communication delay of at the very least a couple of minutes, so the helicopter wants to have the option to fly itself and keep in touch with the rover.
