NASA's Ingenuity helicopter survives first night alone on Mars

NASA's Ingenuity mini-helicopter has survived its first night alone on the frigid surface of Mars, the US space agency said, hailing it as "a major milestone" for the tiny craft as it prepares for its first flight, AFP reports. 

The ultra-light aircraft was dropped on the surface on Saturday after detaching from the belly of the Perseverance rover, which touched down on the Red Planet on February 18.

Detached from the Perseverance, Ingenuity had to rely on its own solar-powered battery to run a vital heater to protect its unshielded electrical components from freezing and cracking during the bitter Martian night, where temperatures can plunge as low as minus 130 degrees Fahrenheit (minus 90 degrees Celsius).

Making it through the frigid Martian night was "a major milestone for the small rotorcraft," NASA said in a statement Monday.

"This is the first time that Ingenuity has been on its own on the surface of Mars," said MiMi Aung, Ingenuity project manager at NASA's Jet Propulsion Laboratory.

"But we now have confirmation that we have the right insulation, the right heaters, and enough energy in its battery to survive the cold night, which is a big win for the team. We're excited to continue to prepare Ingenuity for its first flight test."

Over the coming days, Ingenuity will undergo tests of its rotor blades and motors.

If all goes well, Ingenuity is expected to make its first flight attempt no earlier than the evening of April 11, the Jet Propulsion Laboratory said.

It will be the first aircraft to attempt powered, controlled flight on another planet.

Ingenuity is carrying a small piece of cloth that covered one of the wings of the Wright brothers' first aircraft which achieved the first powered flight on Earth at Kitty Hawk in 1903, to pay tribute to the milestone.

Its attempt will also coincide with the 60th anniversary of the first human space flight, by Soviet cosmonaut Yuri Gagarin on April 12, 1961, and 40th anniversary of the April 12, 1981 launch of the first space shuttle, Columbia.
