We had a drive up to the outcrop on sol 238. This site is on the other side of the ridge called Martre from the last abrasion at Bastide.

A small adjustment to the position on sol 239. Perseverance is now sitting at the base of the outcrop imaged on sol 238 (before the sol 238 drive, so at the sol 237 location) and shown here by Tau. But the rover is facing away from the outcrop at the moment.

I have added Ingenuity's flight 15. It landed a little north of the targeted site. I am assuming it will be called Airfield F again.

I have added Supercam names from PDS to one of the earlier maps. I will update others as I can get to them.

Perseverance has started its return journey to the landing site (presumably), and to reduce clutter and confusion in the maps I will make a separate map for the return journey, both for the rover and for Ingenuity. This map is updated to sol 279 for the rover and omits the last two return flights of Ingenuity. The next map will follow both of them.
I modified the straight line flight of Ingenuity on sol 163 based on my own mapping of Ingenuity images, but I may have exaggerated the kinks in the path. That might be partially straightened after I have thought about it a bit more. Phil -------------------- ... because the Solar System ain't gonna map itself.

A small move on sol 283, presumably setting us up for a study of some interesting target, maybe the sand ripple.

Phil, I'm sorry for presenting the table in this manner: this forum has no BBcodes for displaying tables copyable as text.
The forum engine also didn't allow me to attach the *.geojson file which was used as the data source. Its download link at NASA site (mission map nicknamed 'Where is the rover') is uncopiable - but to explain in words, it is available in the hidden 'Export to JSON' under the 'hamburger' button at top left. I built this table in Excel to verify the flight lengths displayed in the official Flight Log (column "f.log") with the calculations based upon areocoordinates and the so-called "northings" / "eastings" (column "calc") which I treat as offset from equator / zero meridian in metres. Flights marked with the asterisk (*) are hops, roundtrips and other multileg 'brackets' where data is not comparable by default: the object of my investigation are straight routes where "f.log" must be equal to "calc". Flight f.log calc northing easting N E 1* 0 0,05 1093314 4354502 18.44486 77.45102 2* 4 0 1093314 4354502 18.44486 77.45102 3* 100 0,76 1093314 4354502 18.44486 77.45102 4* 266 6,1 1093313 4354501 18.44486 77.45101 5 129 130,81 1093313 4354507 18.44486 77.45112 6* 215 100,75 1093183 4354522 18.44267 77.45139 7 106 106,3 1093124 4354441 18.44166 77.44994 8 160 160,48 1093018 4354453 18.43988 77.45015 9 625 620,33 1092862 4354489 18.43724 77.45079 10* 233 97,51 1092319 4354188 18.42808 77.44545 11 383 388,24 1092319 4354091 18.42808 77.44545 12* 450 26,19 1092590 4353813 18.43266 77.43878 13* 210 12,14 1092592 4353840 18.43269 77.43924 14 2 1,53 1092603 4353834 18.43287 77.43915 15 407 410,51 1092602 4353836 18.43286 77.43917 The ratio "reported / calculated" for the straight flights shows the tendency of undervaluation (5 cases from 6); the average is 0.9943 or minus 0.57% 5 0.9861631374 7 0.9971777987 8 0.9970089731 9 1.0075282511 11 0.9865031939 15 0.9914496602 One data entry in NASA's json is corrupt: the same coordinates are shown for fligts 10 and 11. Actually while the N value seems to be close to equal, the E values must differ (see airfields F and G). Question 1: what figures for these airfields you use in your maps? Question 2: is there any hope for the total recalculation of these waypoints after helicopter shall return (approximately) to its starting point at Wright Brothers a/f when figures shall explicitly show all errors in previously calculated coordinates / flight lengths accumulated in this 'dead reckoning'? p.s. I shall be grateful if anybody posts here the direct link to the full set of four json files of waypoints/paths for Perceverance / Ingenuity. Thank you. |

I don't use any figures for my airfield locations. I plot them on the HiRISE base image by matching the features seen in the Navigation Camera descent images - the last few images of every flight, usually the first to be transmitted. My locations are relative to the base image, not to any coordinates. In an ideal case they would be the same.

And here is the pilot version of my new chart: absolute elevations of helidromes from JZRO (Wright Brothers Field) through H with maximum flight levels' versus the start airfields. Link to the full-size 1,000×688 image is here. The file is really small (37.017 bytes). Source data credits to NASA/JPL are already written.

Map update to sol 285, with the name I misread is Gras corrected to Bras (the original source was too small to read clearly), and two names at the sol 285 location found By Paul. Thanks to all who contribute to this effort.
