| 25 | April 8, 2022 at 16:40[163] (Sol 403) | 161.3 | 10 m (33 ft) | 708.43 m (2,324.2 ft) | 5.50 m/s (12.3 mph) | Shift northwest flying across northwest Seìtah and crossing the Seìtah region to land at the staging area at Airfield Q 18.45477°N 77.43058°E | The flight was the longest and traveled at the highest rate of speed so far. The mission team chose a route that avoided flying over hardware that was discarded and fell to the surface during the rover's entry-descent-landing (EDL) and might have caused unexpected performance from Ingenuity's laser altimeter and visual navigation system.[162] |
What an accomplishment.
Those solid state electronics will last forever. It will eventually fail due to a mechanical or software failure.
Really great for a proof of concept demo.
The batteries will eventually get where they will not hold a charge.
That poses interesting physics/aerodynamics questions. At what airspeed does effective translational lift occur in Mar’s atmosphere, and is that airspeed within the Ingenuity’s flight envelope.
No....it will ‘fail’ when there is no more money to pay overpaid NASA wonks to issue controls to it. No more money because we as a country pissed it all away on issuing smart phones to hundreds of thousands of illegals so they could ‘check in’ with their handler/court designees. No more money because we forgave untold money in student loans. No more money because, because, because.........just name some BS gibsmedat need and there’s your answer.....
"Real" full-scale helicopters have engines that eventually will not run.
Yes, I think probably you're correct.
That’s beyond my pay grade. :)
Are they trying to sneak this one by? :)
Still nothing on the Twitter page (unless it was buried in a reply for some other tweet). That’s what news people must be watching for the expected updates, because the usual articles are missing as well.
Maybe a light will go on eventually.
“Those solid state electronics will last forever.”
Even solid states circuits have a failure rate. Thermal cycles eventually kill them.
You're correct.
I used to attend failure analysis meetings where the EE's would explain the cause of customer return failures on our chips. One of the most visually interesting failures was an open lead where the metal (alum) had 'flowed' to a 90 degree corner in the lead and just puddled there, behind it was no/open lead. Where the lead had been was visible but contained no metal.
It was described as an 'open' due to metal ion flow from an electron wind. Seems the metal ions had been swept along the lead by the electron flow until it got to a corner it couldn't turn.
We changed two things as a fix, a chip design rule change, no 90 degree turns on metal leads and a new nitride seal on top/side of the metal leads.
Maybe Ginny has had so many successful flights that NASA thinks one more is nothing special.
I thought nitrates and nitrites were bad for you.
Refractory metal nitride films are widely used in applications requiring materials with good conductivity and resistant to high temperatures and oxidizing ambients. These films are used for electrodes in devices such as capacitors and transistors, and as an adhesion / barrier layer for interconnects in semiconductor chips.

Sure, after 2,000 flights.
Weird stuff:
They put out a massive status update (unusual) in anticipation of this flight, with analysis of each potential route, laying out the details and pros and cons of A, B, and C, leading to the “big reveal” at the end and these last words:
“See you at the delta!”
And then... crickets. Flight 25 was added to the flight log either last night or this morning, without any fanfare. Wiki had it up a couple days ago but with an “awaiting confirmation” notice over the entry.
Well they forgot Ginny’s birthday, so who knows.
Get through *that* page and by comparison no post of mine of FR will ever seem to drrrone on. :)
#MarsHelicopter is breaking records again!
Ingenuity completed its 25th and most ambitious flight. It broke its distance and ground speed records, traveling 704 meters at 5.5 meters per second while flying for 161.3 seconds. http://go.nasa.gov/2U43zuH

They got around to linking back to the flight log.
Bacon. I was thinking bacon. :)
