Ingenuity made its 55th flight on August 12, 2023, what demonstrates the
robustness of the control GNU/Linux system, including in particularly
hostile conditions, an unknown environment and minimal supervision,
because the helicopter is almost autonomous, very very far from
everything somewhere in space.
