NASA's experimental Ingenuity helicopter has turned into a Mars scout.

"In fact, they will have to spin faster than we have ever attempted with Ingenuity or any of our test helicopters on Earth.".

NASA JPL said Ingenuity did a rotor spin test and could take off on its 14th flight as early as today.

The #MarsHelicopter did a rotor spin test at 2,800 rpm.

Grip warned of possible issues that could come with increased rotor speeds.

"The motors will need to spin faster, the electrical system will need to deliver more power, and the entire rotor system will need to withstand the higher loads that come with increased rotor speeds," Grip said.
