#flight72 — Public Fediverse posts

I believe we can now reconstruct the last moments of #Ingenuity's #Flight72 with some certainty. The actual trajectory may be a little more complicated, e.g. turning while hopping, but we'll never know.

EDIT: there is a new theory about Flight 71, see comments.

#Ingenuity is indeed visible from the new location at RMC 51.3688. Especially the marks from its first bounce upon landing of #Flight72 should now be visible from a very favorable new angle, although of course not in this wide angle NAVCAM image.

There are some new marks visible on the regolith ripple, that were previously hidden behind the crest. This will definitely change the way the #Flight72 landing events have been interpreted by the #MarsHelicopter team.

A reworked hypothesis about #Ingenuity's last #Flight72 explained with an animation. It is based on a number of assumptions, most of which come out of #NASA's statements.

Finally, on Sol 1059, #Ingenuity turned its blades to a new position, and it seems most (or all) of the 4th blade is missing.

EDIT: Smoother animation with more images

Some forensic analysis for #Ingenuity's final #Flight72.

It looks like there may be many additional places where the blades/feet hit the regolith during the last flight of the #MarsHelicopter.

Another view of #Ingenuity from 450m afar, at its final landing after #Flight72. Its size in this 110mm MCZ image is a mere 30px, but it seems as if there are two gouges in the regolith, to the left of the heli, caused by its blades hitting the ground during landing.

#Perseverance #MarsHelicopter #Mars2020 #Solarocks #Space

Another sol, another drive for #Perseverance. The rover is approaching the northern edge of the rocky Margin Unit, getting closer to where #Ingenuity is located after its eventful #Flight72, but it still has no line-of-sight to the #MarsHelicopter. It may be in a better position for a first look in a sol or two, as seen in the visibility plot below.

The path shown is a guess.

The maps were made with #QGIS using data from #NASA's #MMGIS, #USGS and #HiRISE

Here is a fresh animation of images captured by #Ingenuity from 06:06 to 09:17 AM tosol, Sol 1043, showing clearly that at least two of the 4 rotor blades were damaged during #Flight72.

Dissecting #Ingenuity's accident.

This animation shows one of the rotor blades before and after the #MarsHelicopter's 72nd landing. The fact that the image with the broken blade had to shrink and change perspective so much to match the other one is an indication of the RTE camera being much closer to the ground after landing 72.

Superimposed, transformed RTE images from #Flight69 and #Flight72.

The end of #Ingenuity's mission on Mars.

As I have been posting lately, images and events around #Flight71 and #Flight72 indicated that something had gone wrong with the #MarsHelicopter (see next post for references)

#NASA's new status update confirms that #Flight72 was the last one for the mighty little helicopter.

as if something dragged or hit the ground during #Flight71 (https://mastodon.social/@65dBnoise/111750833533763835)

The fact that there is just one image from #Flight71 attests to the fact that communication with the rover was already bad before the flight, and probably remained bad after popup #Flight72 which landed at about the same location.

#MarsHelicopter #Ingenuity #Mars2020 #NASA #Solarocks #Space

#Perseverance lost communications with #Ingenuity during the #MarsHelicopter's descent for landing after its pop-up #Flight72, a few sols ago.

The helicopter was already out of sight and at a distance of ~1km, as seen in the map below. There is an obstructing mound about midway that rises 13m above the line-of-sight, which might be the reason for the loss of signal. Despite that, assuming Ingenuity's landing software worked as usual, the helicopter may be in good health, but

#Ingenuity might be going through some hard times, it appears. Communications terminated early during #Flight72 just before touchdown, a (rare) postflight JPL status update says:

#MarsHelicopter #Mars2020 #NASA #Solarocks #Space

#Ingenuity is ready for a pop-up #Flight72 up to 12m, on Sol 1036, so that the team (and we) can see where it ended up after its emergency landing. We'll also see those deep marks it made in the regolith and have something more solid to speculate upon.

Goal of flight: Localization.
