Mars Helicopter Ingenuity runs/spins rotor blades motors for the first time

On April 9, 2021 NASA’s Perseverance Mars Rover sent images of Ingenuity Helicopter’s rotor blades spin up within motor test. Ingenuity is ready to make First Fly on Mars on April 11-12. Rotor blades spinned up and are unlocked and helicopter is going to make high-rpm test. So next milestone is to spin up rotor blades full-speed for the first time on Mars (to the planned flight speed of ~2400 RPM) while still on the surface. When Ingenuity is flying, it uses a lot of power-many hundreds of watts. The lithium-ion battery that powers Ingenuity's two main propulsion and six blade pitch control motors needs to handle power surges as Ingenuity flies and fights any winds and gusts it may encounter. The helicopter's voltage needs to be maintained so that motors do not stall or electronic devices get in trouble. Ingenuity comes out of the cold Martian night without much energy in its battery, so it needs to bask in the Sun to warm up and let the solar panel charge up the battery enough to handle the power demands of the day. All this means that Ingenuity cannot fly too early in the morning. Midday and afternoon are far better.
