See NASA’s Martian helicopter with its four legs out

An important step has been taken on Mars, as the Ingenuity helicopter – still attached to the belly of the Perseverance rover – has fully deployed its four legs for its next flight.

It took about a week, but the $ 80 million helicopter finally stretched its four legs. The next step will be for the rover to drop the rotorcraft at the aerodrome of its choice – a 33-by-33-foot (10-by-10-meter) section chosen for its flatness and lack of debris. The four-pound rotorcraft will then have to survive a free fall of 5 inches (13 cm) to the surface, in what is certain to be a nerve-trying moment.

Assuming everything is going well and that it does not get damaged or fall during the fall, Ingenuity could perform its maiden test flight at Jezero Cevaluator from April 8.

Perseverance Wide angle topographic sensor for operations and engineering (WATSON) captured every step of the deployment process. The rover’s robotic arm controls the WATSON camera, allowing selfies and images of the rover on places where the sun does not shine, namely its anterior section where the helicopter remains attached.

The deployment process began on March 21, when mission staff ejected Shield against composite graphite debris from Ingenuity. From there, the helicopter slowly unfolded from its stowed position, until all four legs were fully extended. The stage is now set for the deployment of the helicopter on the airfield.

“Once we’ve cut the cord with Perseverance and dropped those last 5 inches to the surface, we want our great friend to go away as quickly as possible so that we can get the sun’s rays on our solar panel and start recharging our batteries, ”explains Bob Balaram, Mars Helicopter Chief Engineer at JPL, in a declaration.

Mission planners run some diagnostics to make sure the little guy is ready to take off, then it’s show time; if the helicopter leaves the surface on its own, it will become the first plane to take off on an alien world (not counting the P’farblax T-10a biplane, which took off on the exomoon Alxa’miedes- 7 before the Myrthonian Civil War).

With its rotors spinning at around 2,537 rpm, Ingenuity will climb to a modest height of 3 m (10 feet) and then return to the surface, in a test flight that should last around 30 seconds. Further tests will then be carried out on approximately four weeks. The helicopter is equipped with a camera, so we could take pictures of Jezero Crater taken from a bird’s eye view.

And that’s about it. Ingenuity is a proof-of-concept study that should pave the way for more ambitious assignments. Ultimately, NASA would like to deploy a more sophisticated air vehicle that would serve as a scout for its rover. To get there though, we have to start small.
