    NASA’s Ingenuity Mars Helicopter breaks world records, again

    NASA’s Ingenuity Mars Helicopter has been flying on the red planet’s surface for over two years now, and it has covered a distance of over 11 kilometres in that time. While 11 kilometres in two years may not seem like much in Earth terms, Ingenuity is actually breaking world records on the Mars.

    Ingenuity’s 49th flight, which happened on Sunday, April 2, broke two different records–that for the highest altitude and the highest speed–achieved by any self-propelled aircraft outside of Earth. During its 49th flight, the little rotorcraft flew up to a height of 16 metres and reached a top speed of 23.4 kilometres per hour.

    The rotorcraft set its previous flight height record on the red planet on December 3, 2022, when it flew about 14 metres in the air. Its previous flight speed record of 19.8 kilometres per hour was achieved on three different occasions–December 10, June 11, and April 8.

    Its longest flight so far was its record-breaking 25th flight on April 8, 2022, when it covered a distance of a whopping 704 metres in what is still its longest flight and was its fastest flight until flight 49.

    What is Ingenuity?

    Ingenuity is a small solar-powered helicopter that landed on the Martian surface on February 18, 2021, along with the Perseverance Rover. On April 19, the same year, it created history by completing the first powered extraterrestrial flight in human history. During that flight, it hovered and landed and the same spot for a flight that lasted 39.1 seconds, creating history.

    Why are Ingenuity’s records so impressive?

    While these distances may seem small for us here living on Earth, do remember that Mars is more than 225 million kilometres away right now. The distance between the two planets means that it takes between 5 to 20 minutes for a signal to travel from one to another.

    Adding to this signal delay, Ingenuity also has to survive the harsh conditions on Mars. The low atmospheric density on the planet means that Ingenuity must work much harder than helicopters here on Earth in order to be able to fly. Also, it has had to survive “continent-sized” dust storms in the past and other Martian hazards in the past.

    NASA’s Mars helicopter has just set a new flight record

    NASA’s plucky Ingenuity helicopter set a new flight altitude record on Mars on Saturday.

    In a mission lasting 52 seconds, the 4-pound, 19-inch-tall machine reached a height of 46 feet over the martian surface while traveling a distance of 49 feet.

    While most of Ingenuity’s 35 flights on the red planet have reached a peak altitude of 33 feet, the weekend excursion by the drone-like device topped the existing record of 39 feet achieved on three separate flights last year.

    Ingenuity reached Mars with NASA’s Perseverance rover in a spectacular arrival captured in high-definition video in February 2021.

    Two months later, following a period of ground-based tests, Ingenuity became the first aircraft to achieve powered, controlled flight on another planet with a 39-second hover 10 feet off the ground. Its longest flight to date covered a distance of 2,325 feet in a mission in April 2022.

    Although the helicopter was sent to Mars to merely test the viability of using such a machine for future planetary missions, Ingenuity performed so well that NASA started using it to assist the ground-based Perseverance rover as it searches for evidence of ancient life on the planet.

    The aircraft helps by using its downward-facing camera to search for areas of interest for Perseverance to explore. The aerial vantage point also allows the team to use the imagery to find the safest and most efficient routes for Perseverance to take as it makes its way across the rocky surface to different exploration sites.

    Ingenuity’s record-breaking flight came 11 days after the flying machine set another record, for the shortest flight in Mars aviation history when it hovered 16 feet off the ground for a mere 18 seconds. The mission was an important one, however, as it gave the team a chance to test two new capabilities, specifically, hazard avoidance for landings and digital elevation maps to aid navigation.
