NASA’s Mars Ingenuity helicopter will make the first attempt at powered, controlled test flight on another planet in early April, the US space agency said on Tuesday.
If all goes to plan, the flights will be considered a proof of concept that could revolutionize space exploration.
Such future aircraft would shorten expedition times and enable rugged terrain research.
What is Ingenuity and how it got to Mars?
Ingenuity is a tiny helicopter that weighs 1.8 kilograms. Despite its small size it came with a hefty price tag, costing NASA around $85 million (€71.7 million) to develop.
The small detachable aircraft hitched a ride to Mars on the underside of NASA’s Perseverance rover, which landed on Mars in February.
When do we know about the flight?
The helicopter is currently making its way across the planet to the test flight “airfield” strapped to the rover.
NASA did not provide a specific date for the first flight, but the mission’s chief engineer Bob Balaram said it could take place around April 8.

The helicopter has been developed to fly in an atmosphere that is 1% the density of Earth’s, which makes achieving lift harder. It will be assisted by a gravity that is one-third of planet Earth’s.Its rotor blades would need to spin about five times faster to achieve the same amount of lift as back on our home planet.
Its first flight will involve climbing at a rate of about one meter (three feet) per second to a height of three meters, hovering there for 30 seconds, then descending back to the surface…
