White Science: HUGE SUCCESS: The Little Martian helicopter keeps going and going and going

[The first ever flying vehicle on another planet, the little Martian helicopter (a project conceived and run mostly by Whites), is a huge success. It's levels of success must surely be blowing away the scientists, technicians and creators. Originally they hoped for 5 flights I think. They're now up to 18. So it's an enormous success. I think the future of FLYING ROBOTS ON MARS IS GOING TO BE HUGE and this will no doubt be extremely useful when looking at other planets which have atmospheres. Mars' atmosphere is very thin, so flying in it is actually hard. There are planets with much thicker atmospheres. Amazing stuff is possible … brought to you by Whites … whatever Whites are still left at NASA. The Martian atmosphere is getting thinner due to a seasonal change, but NASA was testing higher rotor spinning speeds to see if they can still keep the helicopter going! Jan]

NASA’s Mars helicopter Ingenuity has soared through alien skies yet again.

"The #MarsHelicopter keeps going, going, going! Ingenuity successfully completed its 18th flight, adding 124.3 seconds to its overall time aloft on the Red Planet," officials with NASA’s Jet Propulsion Laboratory (JPL) in Southern California, which manages Ingenuity’s pioneering mission, said via Twitter today (Dec. 17).

Ingenuity covered 754 feet (230 meters) of ground while cruising at 5.6 mph (9.0 kph) during the flight, which took place on Wednesday (Dec. 15), JPL officials added.

The 4-lb. (1.8 kilograms) Ingenuity landed last February with NASA’s Perseverance rover on the floor of the 28-mile-wide (45 kilometers) Jezero Crater, which hosted a big lake and a river delta billions of years ago.

Ingenuity’s main goal was to show that powered flight is possible in the thin air of Mars. The little chopper checked off that box over the course of five initial flights, then shifted into an extended mission during which it has been pushing its limits and serving as a scout for the life-hunting, sample-caching Perseverance.

The rotorcraft has performed extremely well, racking up an impressive set of off-Earth accomplishments. Ingenuity has now spent nearly 33 minutes aloft in the Martian air, for example, and visited 10 different Red Planet airfields.

"Few thought we would make it to flight one, fewer still to five. And no one thought we would make it this far," Ingenuity team lead Teddy Tzanetos of JPL said in a statement earlier this week. "The aircraft’s continued operations speaks to the robustness [of] the design and the diligence and passion of our small operations team."

That’s not to suggest that it has all been perfectly smooth sailing for the little chopper. For example, during its sixth flight, which took place on May 23, Ingenuity suffered a glitch that interrupted the flow of navigation images to its onboard computer.

And the communications link between Ingenuity and Perseverance was disrupted during the chopper’s descent on flight 17, which occurred on Dec. 5. This complication delayed the mission team’s assessment of the sortie, which was eventually determined to be a complete success. (All of the helicopter’s data and imagery reach Earth via Perseverance and Mars orbiters.)

Some people have speculated that the Dec. 5 communications dropout may be linked to log4j, a widely used programming code developed by the nonprofit Apache Software Foundation that was recently revealed to have a flaw that can leave it vulnerable to hackers. But this is not the case, JPL officials said, pointing instead to a much more prosaic cause.

"NASA’s Ingenuity helicopter does not run Apache or log4j, nor is it susceptible to the log4j vulnerability. NASA takes cybersecurity very seriously and, for this reason, we do not discuss specifics regarding the cybersecurity of agency assets," JPL officials wrote in an update Thursday (Dec. 16).

"The interruption in data communications between the Ingenuity helicopter and the base station on the Perseverance rover during flight 17 occurred when the signal was blocked by elevated terrain between the two as Ingenuity descended at the end of the flight," they added. "Effectively, Ingenuity ‘flew behind a hill’ or out of the rover’s line of sight, briefly interrupting high-speed communications between the two spacecraft."
