NASA has wonderful news for its plucky Mars helicopter

By Trevor Mogg March 15, 2022

NASA’s Ingenuity Mars helicopter made history in April 2021 when it became the first aircraft to achieve powered, controlled flight on another planet.

With Mars’ atmosphere much thinner than Earth’s, engineers at NASA’s Jet Propulsion Laboratory (JPL) weren’t certain if they could build a machine capable of obtaining lift on the red planet, let alone creating one able to fly reliably. But with its long, fast-spinning blades, Ingenuity has exceeded expectations, flying over long distances during multiple flights.

Since its first flight, the 4 pound, 19-inch-high helicopter has flown a further 20 times, traveling as far as 625 meters in a single trip, reaching altitudes as high as 12 meters, and zipping over the martian surface at speeds of up to 5 meters per second.

With Ingenuity showing no signs of mechanical decline, JPL has just announced that it’s extending the flight operations of the plucky copter through September, a fabulous development that puts it on a path toward “setting more records,” the team said.

JPL has recently made several adjustments to Ingenuity’s flight software that will now allow it to fly higher and also to change airspeed as it flies. Future software upgrades could include adding terrain elevation maps into the navigation filter and a landing-hazard-avoidance capability, JPL said.

Looking ahead, JPL says Ingenuity’s new area of operations will be “entirely different from the modest, relatively flat terrain it has been flying over since its first flight last April.”

It means that in the coming months the aircraft will be taking on an ancient river delta in Jezero Crater, using its onboard camera to identify areas of interest that NASA’s Perseverance rover can explore in search of evidence of past microbial life on the distant planet.

“Several miles wide and formed by an ancient river, the fan-shaped delta rises more than 130 feet (40 meters) above the crater floor,” JPL said. “Filled with jagged cliffs, angled surfaces, projecting boulders, and sand-filled pockets that could stop a rover in its tracks (or upend a helicopter upon landing), the delta promises to hold numerous geologic revelations — perhaps even the proof necessary to determine that microscopic life once existed on Mars billions of years ago.”

Commenting on Ingenuity’s success, Thomas Zurbuchen, the associate administrator of NASA’s Science Mission Directorate, said: “Less than a year ago, we didn’t even know if powered, controlled flight of an aircraft at Mars was possible. Now, we are looking forward to Ingenuity’s involvement in Perseverance’s second science campaign. Such a transformation of mindset in such a short period is simply amazing, and one of the most historic in the annals of air and space exploration.”

It hasn’t all been smooth sailing for Ingenuity, however, with JPL engineers having to remotely solve a number of technical issues experienced by the drone-like flying machine. Still, overcoming the problems from so far away is testament to Ingenuity’s amazing design, and gives JPL a great deal of hope as it considers more advanced aircraft designs for future Mars missions.

NASA’s Mars helicopter aces longest flight in almost a year

NASA's Ingenuity helicopter.

NASA’s Mars helicopter recently aced its 43rd flight, one that turned out to be its longest in almost a year.

During the February 11 flight, Ingenuity traveled 1,280 feet (390 meters) across the martian surface for 146 seconds, reaching a maximum altitude of 40 feet (12 meters) while reaching a top speed of 8.9 mph (4 meters per second). The flight was a repositioning mission in preparation for providing further assistance to NASA’s Perseverance rover as it continues to explore Jezero Crater.

NASA’s Lunar Flashlight satellite won’t make it to its planned orbit

This illustration shows NASA’s Lunar Flashlight carrying out a trajectory correction maneuver with the Moon and Earth in the background. Powered by the small satellite’s four thrusters, the maneuver is needed to reach lunar orbit.

This week has seen good news for one NASA moon mission, as the CAPSTONE satellite recovered from a communications issue, but bad news for another. The Lunar Flashlight mission, which is intended to search the south pole of the moon for water ice, now won't make it to its planned orbit.

Ingenuity helicopter helps researchers learn about dust on Mars

The Ingenuity helicopter is pictured on the surface of Mars.

One of the big challenges of Mars exploration is something very small: dust. Fine dust covers much of the martian surface, and high winds and low gravity mean the dust is easily whipped up off the surface, covering solar panels and gumming up components. The Ingenuity helicopter has had its own problems with dust on its solar panels, limiting the amount of power it could draw from the sun.

Now, researchers have used data from Ingenuity to understand more about how dust moves in the martian air, learning about the dynamics of dust, which could help future missions deal with this ongoing problem.
