Watch a replica of NASA’s Mars helicopter take flight on Earth

Visitors to NASA’s Jet Propulsion Laboratory (JPL) in Southern California at the weekend got to see a life-sized replica of the Ingenuity Mars helicopter take flight.

Ingenuity made history in April 2021 when it became the first aircraft to make a powered, controlled flight on another planet. It’s since gone on to complete more than 50 Mars flights and has even assisted NASA’s ground-based Perseverance rover by taking aerial images to help the JPL team plan safe and efficient routes across the Martian surface.

JPL this week shared a short video (below) of its replica Ingenuity buzzing about on Earth:

The weekend’s Mars helicopter demonstration was part of the first Explore JPL event in four years after the pandemic prompted its suspension. Visitors could witness the 4-pound, 19-inch-high drone-like machine taking short flights in the same way that Ingenuity has been doing on Mars.

The conditions for the Earth flights were, however, a little different.

For starters, the atmosphere on Mars is 100 times thinner than here on Earth, making it more of a challenge for engineers to design a machine capable of sustaining stable flight.

To achieve this, Ingenuity’s carbon-fiber blades — arranged into two rotors — spin at 2,500 revolutions per minute (rpm), way faster than the approximately 500 rpm used by helicopters on our own planet.

Also, for the JPL event, a pilot stood close by to control the replica aircraft, but the real Ingenuity receives flight instructions from more than 160 million miles away before deploying onboard guidance, navigation, and control systems to ensure a safe flight.

More than 20,000 people attended the event at JPL’s base just north of Los Angeles. Visitors were able to learn more about JPL’s missions past, present, and future, and could even chat with JPL personnel and ask questions about their work.

Explore JPL is an occasional event, so check its website for details on the next one. It also holds free in-person and virtual tours of its facility.

NASA Mars rover has discovered an alien rock

While NASA’s newer Perseverance rover usually gets all the headlines, 11-year-old Curiosity continues to trundle across the surface of Mars in search of interesting discoveries. And it’s just made one.

Ashley Stroupe, mission operations engineer at NASA's Jet Propulsion Laboratory (JPL), which is overseeing the Curiosity mission, said on JPL’s website last month that the rover had happened upon a 1-foot-wide rock that “seems to have come from elsewhere.”

Mars helicopter Ingenuity marks 40 flights and is still going strong
Ingenuity sits on a slightly inclined surface with about 6-degree tilt at the center of the frame, just north of the southern ridge of “Séíitah” geologic unit. The Perseverance rover’s Mastcam-Z instrument took this image on Dec. 1, 2021, when the rotorcraft was about 970 feet (295 meters) away.

The Mars helicopter Ingenuity has made its third flight of the year, which also marks its 40th flight since it landed in the Jezero crater along with the Perseverance rover in February 2021. Despite being originally intended for just five flights and having to weather the Martian winter, the little helicopter is still going strong as it comes up to its second anniversary on the red planet.

On the helicopter's 40th flight, it traveled from an area named Airfield Z to Airfield Beta, on its way to join the Perseverance rover as it explores the Jezero river delta. It will help scout ahead for the rover, identifying safe routes for the rover to drive as it searches for evidence of ancient life that could have existed when water was present on the planet's surface billions of years ago.
