First route map! I will keep it going, mostly on LROC images, as I need it for a future project. I am still working on an accurate scale.

Now that we have six wheels on soil we need a dedicated route map thread The usual route map thread rules apply -- no chit-chat in there, keep it clean for just map updates.

Could we re-post the landing site location images here, so all the relevant mapping material is in the one place?

Thanks, Thorsten and Phil,
I watched a lot of CNTV live stream after the deployment of Yutu, and in one of the interviews an engineer showed a map of the early stages of the Rover's intended route. It showed a curved route going down the east side of the lander, which was said to be in order to photograph the sunlit side of the Lander (which makes sense). It then came in behind the south side of the Lander (I think they said to photograph the Chinese flag on the Lander ), and made a short move directly further south. There were 3 or 4 stops marked with blobs, indicating mutual photo stops. Unfortunately this was up too fast for me to get a screen grab. I have searched the several clips from that coverage here and elsewhere, but that part does not appear to be one that was clipped and posted for later re-play. China TV English Chang'e Report |

Total distance travelled to date, according to Xinhua today...
"The six-wheeled rover started moving again after shutting down its subsystems on Dec. 16, and has traveled about 21 meters as of 8:05 p.m. Beijing Time on Saturday, according to the BACC." |

I mean it : you succeed so well in adding locations on the Moon for a probe and its rover for which we have barely (as Westerners) no hi-res imaging data at all (and I would say with no access to an outreach policy as we have in Europe or in the USA). CONGRATULATIONS, Phil ! (and Merry XMas) |

this link (in Chinese) gives some details of the future objectives of Yutu's traverses:
http://news.xinhuanet.com/mil/2013-12/24/c_118692396.htm a "large stone pyramid" about 42 meters SW of the lander, the a high ground to the W and a crater 10 m to the N. the link also gives some detail of the driving sessions. |

The pyramid will be the large rock in the corner of my route map (and its pyramid shape well seen in the circular pan I posted). The high ground is most likely the rim of the 60 m diameter crater west of the lander, bristling with rocks in the panorama view. The other crater is probably the blocky one just north of the lander. After that the article says they are contemplating a strategic path for long term objectives.

This is a very tentative map update. We have no images to help with the current position, but there is a report that the rover is 40 m south of the lander and 'a little bit left' which I am interpreting to mean left on a north-up map, not left as the rover drove.
So... position is very tentative and the shape of the route unknown, and even the date of the drive is uncertain. So all this may be changed later. But for now it's the best we can do. Phil -------------------- ... because the Solar System ain't gonna map itself.

Merci! Here's another update including a sketch of the lander - though I'm not sure of the exact dimensions of the lander... and corrected to use the LRO position for Yutu.
Since we will presumably never have daily status reports, this map will always be a work in progress, updated from every scrap of information we get. Phil -------------------- ... because the Solar System ain't gonna map itself.

LRO can make up for the lack of reports quite easily, given the regular flyover schedule. I expect you'll miss learning any creative names they give to sites and targets more Phil (if they even have more than numbers)!

Map update to 14 January - I don't know the date of the drive or the path, so this is conjectural, but the position should be OK. Since the last map I have corrected the size of the lander.

In a Chinese news report from Jan 14 current position was pictured as -32.61 meters (south) and -24.63 meters (west). Can't say what frame is in use -- either from lander or from the X point at the end of rails. The third number (27.17) relates to Yutu's attitude. The one to the right (129.23) is the Sun azimuth. There's also the fifth number outside of this frame -- Sun elevation (34.42 or so). Hope this helps to check/correct Phil's map.

Similar data were found for points A (15 Dec 2013) and E (22 Dec 2013). With reservations about guessing blurred figures, here are these:
Point A -- 9.03 N, 1.55 E, Az = -171.08 Point E -- 30.97 S, 0.64 W, Az = 174.80 As LRO found Yutu to rest some 30-31 meters from CE3, we should believe positions are consistently measured from CE3. Jia Yang's 'more than 40 meters' may be from point X -- or even along the track. |

Interesting! Here is my map with a 10 m grid superimposed and aligned with the lander. The coordinates match the Jan. 14 position well, except 'point E' refers to the point south of my E.

As you know there has been very little information since mid-January. I have updated this map to suggest where we might be based on three very uncertain thoughts.
1. The direction the lander is viewed from in the most recent image. 2. A statement that the distance driven was 'over 100 m' which I interpret as 'only slightly over 100 m'. 3. An earlier statement that the big rock was a target for the rover instruments. Phil -------------------- ... because the Solar System ain't gonna map itself.

I'm sort of surprised we haven't seen any further photos from LROC that would help localize the rover.

Yes, we are overdue - some were expected during day 2 but have not been released (if taken). I could really use an LROC-NAC about now!

I am updating my route map to show a new estimate of the current position which has been relayed to me privately. That does not mean it is official or certain, only that it is suggested by somebody with connections. I hope to learn more at LPSC.

While the apparent closeness of the lander in the most recent images had made me think it likely they had moved closer, I clearly wasn't confident enough about that to say anything publicly. I would really love an LROC image right about now!

If the distance between the L and R cameras is known (big if?), or could be measured from a lander photo, it would be simple to measure the distance from the lander in the new stereo pair.

Not necessarily. The relative position of the two cameras have huge effects on triangulation. On the other hand if in the image you had features of known size and distance, you could estimate the size and distance of other objects.

Yes, that's what I meant - if you knew the relative separation of the L and R rover cameras, then you can find the distance to the lander. I know information is sparse with this mission. But it may be possible to measure the L/R separation from a lander photo of the rover at known distance, or simply by comparing the L/R separation to the total width of the rover, if that's known reasonably well.
Knowing the L/R separation of the rover cameras (orthogonal to their optical axes), then it's a simple matter of trig to convert the measured parallax between the lander and the distant horizon (effectively at infinity) to the lander distance. (Maybe this is what you meant Paolo - without an absolute direction reference, we could not do this, since the L/R optical axes may not be parallel. But we do have such a reference, given by features on the distant horizon in the images.) |

... (Maybe this is what you meant Paolo - without an absolute direction reference, we could not do this, since the L/R optical axes may not be parallel. But we do have such a reference, given by features on the distant horizon in the images.) Yes, that's what I meant. There is some literature on uncalibrated stereo but worked very little on that topic. Features on the horizon might be helpful to determine the vergence but you still need an object of known size in the images.

AND the degree of toe in, if any. That can be measured in pixels by looking at the shift in features on the distant horizon (effectively at infinity).The basic problem is that we need to know the pixel scale of the camera to convert pixels to an angle. Equivalently, as Paolo says, we need an object of known size and distance to give us a known angle. I'm used to MER/MSL, where we have that info easily available. But I'm guessing that's not the case with this mission. In principle, we could estimate the pixel scale since we have 360 degree pans. So if we can match distant features between the 360 and these new L/R images, we could estimate angles. Or, we could look at rover pancam images from the first lunar days and estimate the pixel scale from the (presumably) known size of the lander and distance from Phil's map. Then you have to assume/guess that those images are full frame rather than cropped. Either way, a lot of work. |

Very quick update based on the new LROC images.
Very interesting! If you look back you will see that the two southern points I mapped earlier were from big display screens in the control room. But of course they might have been target positions rather than real positions. The fact that we never saw a close-up image of the big rock suggests they did not get right up beside it. The tracks are not resolved well enough to be certain of the path here and they might have gone closer. Phil -------------------- ... because the Solar System ain't gonna map itself.

That's very strange. I'm looking at the same images and seeing a simpler track closer to your original one, Phil. Where do you get all the new zigzags from? (And why would they execute them anyway?)

I overlaid the image on my map to get the location exactly right. Other than that it's a matter of interpretation, which marking is part of the track. But I will be looking at it again for a more finished version.

This is a new version of the route map, as complete as I can make it now.
It is based on Chinese maps from the first lunar day, near the lander, and a Chinese map shown at LPSC, modified from my own examination of tracks in images, including a vertical projection of tracks from the middle of day 2, also shown at LPSC. The rover location is from the LROC images and it slightly updates the Chinese map shown at LPSC. Dots are stops between drives, and square symbols are science locations shown on the Chinese map. The dates shown for each stop are my estimates but they may not be correct, as we have almost no reliable information to go on. The rover is shown to scale (approximately) but I don't know its orientation. Phil -------------------- ... because the Solar System ain't gonna map itself.

I have read a new magazine
科学世界/Newton , 2014, issue 4: http://www.kxsj.com/html/zixundongtai/zixu...320/103649.html it gave us a official yutu route map |

This is the same map shown on a poster at LPSC in March. My map was based on the new map, but there are places where other information was used to add to my map, especially images of tracks. If you compare this with the LRO image you see that the final rover location is further NE than the site at the end of this map.

Numbers of positions appear to be straightforward: Nddnn points to lunar day dd, point nn, and a sequential number is added in paretheses. But what is E2, S3, N and H?

I have updated this map to include the newly named rock. I may change this as I learn more about it. Sites with squares are the main science sites (use of APXS or other instruments).

I have just been to a meeting with Long Xiao in which he showed results from a paper submitted but not yet accepted. It contains a wonderful route map which I will use to update mine (giving accurate dates at the various stops in Day 2, for instance) as well as several unofficial crater names. There are other very good results including a fascinating interpretation of the ground-penetrating radar data.
I will post an updated version of my map when the new one becomes public. Phil -------------------- ... because the Solar System ain't gonna map itself.

been reading a few papers presented at this year's IAC congress. according to this one: A Priority Method of cruise direction for the Lunar Rover Yutu traveled a total of 118.9 m. the paper also includes a route map

This is a version of my route map (route still needs to be updated) with the new feature names just published in this paper:
http://www.raa-journal.org/raa/index.php/r...ticle/view/1962 The names are Chinese traditional names for constellations. The big crater west of the landing site is 'Purple Palace', a name for a region of the sky. These are not the same names I referred to a few posts above. I will say more about them as soon as I see them again. Phil -------------------- ... because the Solar System ain't gonna map itself.

What wonderful, poetic names!
And of course extending the Mare analogy, why wouldn't a crater be a pool, well or spring? |

This map adds the names and updates the route to take the most recent maps into account. A reminder - I still don't know the exact dates of stops near the end of the route. The dates I give are only guesses.

I am revising and extending my old Moon book, and just did some work on Chang'E 3. This and some recent publications allow me to revise the route map, and now I am confident I do have the dates correct... though there is still some uncertainty about whether some dates correspond to Beijing time or Universal Time. So here is probably the last update of this thread.
Phil The Chinese names come mostly from a mission overview paper in Space Science Reviews: Li, C. et al, 2015. The Chang’e 3 Mission Overview. Space Science Reviews, v. 190, pp. 85-101. -------------------- ... because the Solar System ain't gonna map itself.
