NASA's Ingenuity Mars Helicopter Captures Video of Record Flight

9197_PIA25321-web.gif

The Ingenuity Mars Helicopter’s black-and-white navigation camera has provided dramatic video of its record-breaking 25th flight, which took place on April 8. Covering a distance of 2,310 feet (704 meters) at a speed of 12 mph (5.5 meters per second), it was the Red Planet rotorcraft’s longest and fastest flight to date. (Ingenuity is currently preparing for its 29th flight.)

“For our record-breaking flight, Ingenuity’s downward-looking navigation camera provided us with a breathtaking sense of what it would feel like gliding 33 feet above the surface of Mars at 12 miles per hour,” said Ingenuity team lead Teddy Tzanetos of NASA’s Jet Propulsion Laboratory in Southern California.

The first frame of the video clip begins about one second into the flight. After reaching an altitude of 33 feet (10 meters), the helicopter heads southwest, accelerating to its maximum speed in less than three seconds. The rotorcraft first flies over a group of sand ripples then, about halfway through the video, several rock fields. Finally, relatively flat and featureless terrain appears below, providing a good landing spot. The video of the 161.3-second flight was speeded up approximately five times, reducing it to less than 35 seconds.

Re: Ingenuity, Scouting Mars by Helicopter

To safe guard a mission that has shown so much value NASA just grounded one of its most important Mars missions as the  planet’s atmosphere has become increasingly dusty. The dust has been a terribly inconvenient factor in our study of the Martian surface.

With winter they did want to allow for charge to keep the helicopter alive until next spring, but dust build up meant dropping power to the battery which in time would cause it to freeze.

It looks like a cloth possibly from the parachute that is seen in the camera images until it drops off.

Re: Ingenuity, Scouting Mars by Helicopter

For SpaceNut re #158 .... There is a possibility the bit of cloth may have been from the original Wright Flyer ... As I understand the situation, a bit of cloth from the flyer was affixed to the helicopter.  At this point, that is no more than a suggestion of a possibility.  Hopefully everyone will be watching for further (more definitive) reports.

Re: Ingenuity, Scouting Mars by Helicopter

For SpaceNut .... rather than create a new topic, I decided to offer this story here.  The development is on Earth, for Earth customers, and due to the low mass of Mars air, I don't expect this machine will work on Mars, but it ** does ** appear to show potential.

Composite-FX Reveals Electric XE-Volt Mosquito Helicopter

By Kenneth I. Swartz

Composite-FX (CFX) revealed a battery-electric version of its popular XE Mosquito helicopter at EAA AirVenture four days after it made its first flight at the company factory in Trenton, Florida, on July 21, 2022.

“We have been wanting to build an electric helicopter for years in order to see how our drive train would work with an electric motor,” said CFX general manager Norbert Richter. “One of the challenges with helicopters is having the right amount of torque at the right engine RPM and weight.”

Work on the project began in January 2022, and all the components were received by early July. Assembly took a couple of weeks and the aircraft made first hover at eight in the evening on July 21. It made five subsequent short flights before CFX loaded the aircraft on a trailer for the 1,400-mile (2353-km) road trip to Oshkosh.

Richter said the XE-Volt aircraft displayed at Oshkosh was the first step in the development of a hybrid-electric helicopter that could meet the requirements of its drone customers who are seeking greater endurance and less weight.

Composite FX first flew its electric XE-Volt on July 21, 2022 before trucking the proof of concept helicopter to Oshkosh for display

CFX currently produces four models of XE helicopters, with around 400 sold as kits to owner-pilots and about 50 sold as drones to commercial and unnamed government and military customers.

The portfolio includes the Part 103 ultralight class float-equipped XEL and heavier XE powered by a 64 hp (48 kW) Zanzottera MZ MZ 202 two-cylinder, in-line two stroke motor; the XE 290 powered by a 90 hp (67 kW) water cooled, oil injected, fuel injected, electronic programmable ignition CFX 800 engine; and the XET powered by a modified 95 hp (71 kW) T62-T2A Solar turbine engine.

The helicopter company was established in 2004 when Dwight Junkin teamed up with John Uptigrove of Alberta, Canada, to develop enclosed cockpit versions of Uptigrove’s open frame Mosquito (later Mosquito Air) ultralight helicopter.

Re: Ingenuity, Scouting Mars by Helicopter

Sort of a wake-up flight as its been sleep throughout most of the mars winter. Ingenuity takes shortest flight in Martian aviation history

NASA’s Ingenuity Mars helicopter recently completed a “short but significant” flight lasting a mere 18 seconds — 13 seconds shorter than its debut flight on the red planet in April 2021. Ingenuity’s shortest flight took place on November 23 and was the aircraft’s 34th to date. Its longest flight up to now lasted 169.5 seconds during a mission in August 2021.

Despite the brief nature of the flight, the success of the short hover just 16 feet off the ground successfully tested two new and important capabilities for the helicopter: hazard avoidance when landing, and the use of digital elevation maps to aid navigation.

“Ingenuity was developed as a technology demonstration and designed to operate on Mars in flat, smooth terrain,”

Software updates should bring more capability to avoid rocky landing fields.

Linux Unplugged: Mars Goes to Shell

In May of 2021 a podcast from "Linux Unplugged" featured Tim Canham, who is the Mars Helicopter Operations Lead at JPL. Apparently Ingenuity runs on Linux. When asked how Ingenuity communicates with Perseverance Tim replied they use a "Zigbee radio". (A radio commonly used for home networks/automation -- turn lights on/off, security systems, IOT - Internet of Things). He said Ingenuity communicates with a payload on Perseverance called a "Base Station". The base station then communicates with Perseverance using a "UART on steroids". (UART chips were used in early PC's to control serial ports. 2400, 4800, 9600 baud). Perseverance then communicates with a spacecraft overhead that sends data to Earth.

They used the Linux equivalent of "ZIP" and "UNZIP" to compress data sent to Earth, saving 20-45 minutes on each leg of data transfer. He also mentioned they got more power than expected from the solar panel allowing Ingenuity to fly longer than planned. The interview with Tim is about an hour long.

For Steve Stewart re #162

I am delighted to have your report to share with members of the local Linux User Group on the third Tuesday.

I had no idea of the nature of the software that might have been used for the helicopter (or anything else in Perseverance).

NASA's Mars Helicopter Just Won't Quit, Resuming Flights After an Untimely Landing

Flight 53 took place on July 22—the first flight to take place after NASA reestablished communication with Ingenuity following 63 days of silence. Ingenuity was supposed to fly for 136 seconds, reaching an altitude of 16 feet (5 meters) above Mars’ surface before descending vertically to 8 feet (2.5 meters) to snap images of a rocky outcrop and collect data for the Perseverance rover. The helicopter then climbed straight up to 33 feet (10 meters), allowing its software to identify areas that are not suitable for landing, before touching down on the surface of Mars.

Unfortunately, the helicopter’s 53rd flight did not go according to plan. Instead, Ingenuity flew for a total of 74 seconds before a flight contingency program called “LAND_NOW” was triggered, causing the helicopter to automatically land. The program was “designed to put the helicopter on the surface as soon as possible if any one of a few dozen off-nominal scenarios was encountered,” Teddy Tzanetos, team lead emeritus for Ingenuity, said in a statement.

The Mars helicopter briefly flew for a 25-second hop on August 3, logging in its 54th flight above the planet’s surface to provide data that could help determine why its 53rd flight ended prematurely, NASA revealed this week.

It has to do with being with sync of frame image to calculated image movement amount.

Re: Ingenuity, Scouting Mars by Helicopter

For SpaceNut re #173

Thanks for both those links!  I found each of them helpful.

However, I doubt that the failure in flight 53 was caused by the same failure that impacted flight 6.

My guess is that the engineering team worked ** that ** time stamp issue to death.

My guess is that something new has occurred.

In any case, this topic is available for anyone to contribute updates as SpaceNut has done.

The program was “designed to put the helicopter on the surface as soon as possible if any one of a few dozen off-nominal scenarios was encountered,”

helicopter’s emergency landing was triggered when image frames from the rotorcraft’s navigation camera didn’t sync up with data from its inertial measurement unit (which measures its acceleration and rotational rates),

The success of its subsequent flight, however, gives the team confidence that the issue can be resolved by updating the flight software to help mitigate the impact of dropped images.
