NASA’s Mars Ingenuity helicopter flight delayed, tech talk team aboard the Red Planet



NASA’s Ingenuity’s first Mars helicopter flight was postponed to April 11 to give teams and aircraft more time to prepare. Originally scheduled to fly on April 8, NASA delayed the flight of the first Mars helicopter and One aircraft to give the Ingenuity team back to Earth more time to explain the helicopter’s energy story. Extra time is also a concern because the team “Extremely careful” in every step that goes in the process.NASA works on Ingenuity Helicopter.Image credit: NASA.

The helicopter, which weighs about 4 pounds, has a 1.2 meter wingspan, is powered by a battery that is charged through a solar panel on the top, and when the battery is full, the helicopter can fly for about 90 seconds, according to NASA, and then has to land safely and charge. Once again enough batteries to turn on the heater on board, as it will protect the helicopter from the Red Planet’s chilly nights.

Ingenuity’s delayed flight on Mars

The past three days have given the Ingenuity team time to read better what the energy cycle looks like, and more importantly, ensure its energy is positive throughout every step of the process. The helicopter’s first flight will take place on a full battery and will take off a few meters during that first flight before returning to the surface of Mars. It won’t be more than about 15 feet tall, according to NASA.

“Next step (Fly for the first time) This is huge, ”said Tim Canham, Mars helicopter operations chief, during a smart Q&A held today. “Could it be safely in flight and landing? That will be a moment of great victory for the helicopters.”

It is currently slated for April 11th, although an official time has not yet been announced. However, the flights will not be live streamed. People returning to Earth will see nothing on the flight until the flight’s telemetry data is retrieved, which will last a few days, or Tuesday, about 40 minutes longer than a day on Earth, NASA said. The Perseverance rover, a rover that recently landed on Mars and brought intelligence to Earth, will watch its flight from about 65 meters away.It will take pictures that will eventually make it on Earth. But it may take some time as well.

Why is NASA’s smart flight a big deal?

What made this first flight a milestone for NASA, in addition to flying the first helicopter on Mars, is that it was completely powered by a pre-programmed sequence. No joystick involved or remote controlled helicopters.

“The sequence (of the flight) was pre-built by a team on the ground,” said the operating engineer. Perseverance, Elio Morillo said during NASA’s Q&A, “These sequences have been tested over the years (but) are pre-canned, we don’t have real-time helicopter controls, they are completely independent. “This poses a huge challenge for the Ingenuity team.What would happen if Mars’ gusts were to occur during flight? Helicopters have sensors that can detect those gusts and correct their path accordingly. Most of the time, the pre-built flight sequences are tested over and over in chambers simulating what intelligence is experiencing on Mars.

The Perseverance will watch Ingenuity’s first flight, about 65 meters from a helicopter on top of Van Zyl Overlook, will be photographed and crews are considering if the rover will be able to record audio. There is a directional mic on the plane. But the team is not sure if it will be able to pick up sound from the helicopter due to its long distances.

After the first flight, persistence and intelligence go their separate ways. The ingenuity begins to charge and prepare for the next flight, and persistence returns to its original mission: to collect samples of Mars for return to Earth during later missions. Although the two vehicles will still communicate over the radio. The base team will talk to Perseverance, and Perseverance will convey a message to Ingenuity, the helicopter will respond to perseverance, and the rover will send a message to Earth.

Ingenuity’s main mission on Mars

As the overall picture of Ingenuity grows, its mission is to demonstrate the technology.

“Intelligence is a test spacecraft for Mars,” Canham said. “It will use very high-detailed recordings … 500 times per second … (for us) to see what happens and characterize the flight on Mars. A fitting analogy is Mars Pathfinder and Sojourner – to try something like never before, and Learn a lot from it … for future engineers and scientists to build bigger and better helicopters for Mars. ”
