NASA has unlocked the ‘blades of glory’ on its Ingenuity helicopter ahead of the small rotorcraft’s maiden flight on Mars this weekend.
The space agency called the reveal of the chopper blades ‘mind-bottling’ in reference to a quote from the Will Ferrell ice skating movie ‘Blades of Glory’.
In a short clip shared on Twitter, the 4ft wide blades can be seen slowly unlocking on top of the tiny 19 inch tall helicopter, ahead of a ‘spin up’ test in the coming days.
Ingenuity is set to take its first flight on April 11, which will see the copter take off, hover in place and then return for landing.
NASA’s Jet Propulsion Laboratory, the team leading the Perseverance mission, tweeted: ‘The blades of glory, aka rotor blades of the #MarsHelicopter, have been unlocked and are ready for testing.’

This will be the first vehicle to fly on another planet, which NASA likens to the Wright Brothers moment on Earth. It includes a piece of fabric from that first Earth flight.
The small helicopter has to undergo a number of tests before NASA will send it up into the Martian atmosphere, the first was to see if it could survive the night.
‘Next, the team will spin up the rotor blades for the first time (to a speed below what would be needed for flight) while still on the surface,’ JPL said in a tweet.
Ingenuity made the 239 million-mile journey to Mars inside the belly of Perseverance until it was dropped to the dust Martian ground April 4.
NASA announced the following day that the $85 million drone survived its first night outside of its travel companion, allowing them to move ahead with their plans.
The small helicopter is expected to soar Sunday, April 11 from a 33-by-33-foot piece of Martian real estate that is the first airfield on another planet.
Once everything is a go, Perseverance will receive information from NASA to relay to the copter, which will then fire up the blades to a speed allowing it to achieve lift.
However, a number of factors have to be perfect for the event, including modelling of local wind patterns informed by measurements taken by the Mars Environmental Dynamics Analyzer (MEDA) system aboard Perseverance.
Ingenuity will run its rotors to 2,537 rpm and, if all final self-checks look good, lift off.
The copter will climb about three feet per second and once it hits 10 feet, it will hover in place for 30 seconds before touching back down on the Martian surface.
This flight, although short, determines if Ingenuity is capable of carrying out the rest of its mission, with another four flights potentially possible in the flight window.
Farah Alibay, Mars Helicopter integration lead for the Perseverance rover, said in a briefing last month: ‘Most of all I think of it [Ingenuity] as an experimental aircraft and this started with the Wright Brothers who brought aerial mobility to travel here on earth in the same way we are hoping ingenuity on Mars.’

Several hours after the first flight has occurred, Perseverance will transmit to Earth Ingenuity’s first set of engineering data and, possibly, images and video from the rover’s Navigation Cameras and Mastcam-Z, a pair of zoomable cameras.
‘From the data downlinked that first evening after the flight, the Ingenuity team expects to be able to determine if its first attempt to fly at Mars was a success,’ NASA shared in a statement.
Flying in a controlled manner on Mars will be far more difficult than flying on Earth, as the Red Planet has about one-third the gravity of Earth’s.
Mars’ atmosphere is also just 1 per cent as dense as Earth’s at the surface.
The copter will climb about three feet per second (1 meter per second) and once it hits 10 feet (three meters), it will hover in place for 30 seconds before touching back down on the Martian surface

During Martian daytime, the planet’s surface receives only about half the amount of solar energy that reaches Earth during its daytime.
Nighttime temperatures can drop as low as minus 130°F (-90°C), which can freeze and crack unprotected electrical components.
To survive the frigid Martian nights, it will need enough energy, generated by its solar powers, to power internal heaters.
Perseverance hosts Ingenuity’s base station, enabling communication with mission controllers on Earth.
The main mission of Perseverance, or ‘big friend’, as NASA calls it, is astrobiology and searching for signs of ancient microbial life on the Martian surface.
It’s continuously sharing new images of the Red Planet, including the rock-strewn landscape that mission command used to find a take-off location for Ingenuity.
Its primary goal is to look for ‘biosignatures’ – signs of past or present microbial life – as well as gathering rock samples.
The rover will drill into the dusty surface and gather material into titanium, germ free tubes in the vehicle’s belly.
NASA aims to gather at least 20 samples with a variety of material that can be brought back to Earth for further analysis.
However, Perseverance is not bringing the samples back to Earth – when the rover reaches a suitable location, the tubes will dropped on the surface of Mars to be collected by a future retrieval mission, which is currently being developed.
