Full Version: Ingenuity- Mars 2020 Helicopter
Yes Olivier, could even give us some Oppy at Victoria vibes !
Ingenuity's latest blog covers some of its recent flights, but it contains a nice map (with place names) and documents some of the recent issues / events

New paper out (open access) on the analysis of the sounds of the Ingenuity helicopter flights. A bit of a puzzle was the modulation of the sound, that we tracked down to a sort of 'lighthouse' emission associated with a slight asynchrony between the two rotor rotation rates.

Really nice work! I'm planning on using it to make my students compute Ingenuity's speed from Doppler effect.
Our first glimpse into Belva crater, from flight 50.

Only 22m between Perseverance and Ingenuity on sol 766, perfect for a nice shot!

Hi thomas, We put some work into the same image!
Couldn't resist contributing my version.
After image enhancement, the checkerboard pattern on the left lower rotor blade became visible.

Wow! Ingenuity captured a really nice picture on its Flight 51 (sol 772), with Perseverance and Belva crater.
Perseverance near Belva crater as seen by Ingenuity on sol 772.
There is a stone with remarkable bluish color in the lower center of the image.
Even in neo56's image in the preceding post with more natural Martian colors, it has a slightly bluish tint.

Edit: The image coordinates of the above mentioned stone are 1995 pixels from the left, 2935 pixels from the top

I might be wrong, but I think this new image also solves the identity of Mt. Julian target.
The helicopter has now flown for over 1.5 hours!

Postcard from Mars, by Ingenuity, featuring Perseverance rover and Belva crater 
Ingenuity's take-off on sol 729 with accentuated dust clouds. The time interval between consecutive images was about half a second.
The raw images were extracted from the gif on this site because I could find only one Mastcam-Z left eye image that contains Ingenuity during the take-off on NASA's raw image site.

Flight 53 did not go to plan. It was much shorter than forecast, and only flew at an elevation of 5 meters. Some data is missing from the JSON file and no images from flight 53 have been placed on the server, but older flight images have been downlinked since the flight landed on July 26th.
The helicopter did sit at Xi airfield for 88 sols, so it may have developed issues. Whatever happened, it's safe on the ground after flight 53.

Pretty spectacular imagery. One might of course wonder if the comms ability is related to the line-of-sight into Neretva Vallis.
Update!
Good news.

NASA’s history-making Ingenuity Mars Helicopter has ended its mission at the Red Planet after surpassing expectations and making dozens more flights than planned. While the helicopter remains upright and in communication with ground controllers, imagery of its Jan. 18 flight sent to Earth this week indicates one or more of its rotor blades sustained damage during landing, and it is no longer capable of flight... Imagery revealing damage to the rotor blade arrived several days later. The cause of the communications dropout and the helicopter’s orientation at time of touchdown are still being investigated.

Man what a shame, but she did good.
When I broke off comments on the Perseverance thread to start this one I thought it might be active for a month or two. Maybe. It was a novel high-risk experiment, and Mars is anything but forgiving.
787 posts, 344,000 thread views, and nearly three years later...never been happier to be proven so very, very wrong.
Ingenuity set new stratospherically high bars for engineering excellence. For project management and execution. For capturing the public imagination and the wonder of planetary exploration. For audacity. For almost anything you can name that represents the best within us as a species.
Deepest congratulations and thanks to the Ingenuity team. Your child of mind and effort was an irreplaceable gift to us all; she has earned her sleep.

That's an evocative image. I remember an early press conference, before Ingenuity's first flight, at which Chief Engineer Bob Balaram made it clear that no ground contact by the rotor blade would be survivable.
Looks like some shards are buried in that gouge.
At the teleconference they mentioned Perseverance will pass within a few hundred meters of the lander and take images, but they won't get closer since they still have their science mission. Once the remaining images are downloaded/ or they spin the rotors a little, we should have a better idea.

I expected them to try flight with that mangled blade, but the higher blade rpms required on Mars are much higher than required for terrestrial flight, and the imbalance might be destructive.
Leave Ginny as a memorial.

Its sad to hear it, but I guess we all knew it had to happen at some point. Three years instead of 1 month is a lot, even in comparison to other NASA machines that worked better than expected. Let's look forward to future Martian helicopters that ingenuity paved the way for.
70-something flights is astoundingly epic and in the class is Spirit snd Oppy.
My model Perseverence based on and R/C co-axial.helicopter is still a joy to fly.

This appears to be a lateral dig-and-drag of the landing strut (top left) in the sand -- bottom of the frame to the top
Whatever the rotors touched is off-frame.

This GIF is from the down-look nav cam, the dig-and-drag is below the Helicopter,
Notice: that it looks like at least two rotors are damaged - the last frame shows the second damaged rotor coming into view

I wonder how Ingenuity landed with this much damage to its rotors and also remained upright. Will be interesting to read the final assessments.
The story of Ingenuity by Eric Berger is really informative : https://arstechnica.com/space/2024/02/befor...ged-to-kill-it/
