Edit: I've included the landing ellipse on it. What do you think?

As ever, great - but no hypothetical path?

Spot On for the ellipse as I understand it - the only ellipse worth using really is the pre-launch ellipse, which my photoshopping shows to be in the same spot as yours there.

>Edit: I've included the landing ellipse on it. What do you think?

I'd label it "southern edge of landing ellipse" since those who have not followed the landing ellipse discussion might not understand which part it is. I would be inclined to make the line narrower since the width of the line was due to the small scale of the original landing site image.

Otherwise, it's fine.

I'd keep the ellipse line large - that demonstrates the level of accuracy to which we know it (and probably just as accurate as when it was defined) To make it thinner would suggest a level of accuracy we just don't have.

Doug

Good point and that crossed my mind after I posted. Actually, the landing ellipse is an area of uncertainty around the landing point and we certainly don't know that zone of uncertainty with precision.

--Bill

So does Oppy get her 6 points when she breaks the plane of the ellipse, or does she need to be completely in the end zone?

She has to be clearly over the line and fully in control of the ball at the time.

No, no, no -- the *ball* has to cross the plane of the ellipse line. That's all that's required.

Oppy is a pretty good running back, she's rushed for well over a thousand yards in this, her rookie season. But who are we going to get to kick the extra point?

Oh, not for the moment.
I had one when we were discussing about the way to Mogollon rim, which makes no sense now.
Future path to Victoria? That would be too much for a guess.



It's a mask based on a copy&paste from your previous post, that's why they are at the same spot.

She gets the extra point when she sights Victoria in full back behind the goal line.

Right, the hypothetical paths were done because that area north of Erebus was a big Skinner Box and we didn't know which way Oppy would go.

My guess for a possible path would be along the light bedrock exposure in a southeast direction with stops as needed. After that, who knows? Hopefully by that time we'll have orbital imagery from MRO for guidance.

OT: The landing ellipse issue reminded me of an indication about the Greenwich meridian in the highway going from Madrid to Barcelona.

Google found me this: http://www.microsiervos.com/archivo/mundor...-greenwich.html (Text in spanish, but there are some pics to the right)

Outside of ellipse line, is like as an unknown terrain so, after crossing that line, Oppy becomes an interprid adventurer and it must take own risks on their hike toward to Victoria crater.

Anyone care to estimate where that pile of dark rocks (we passed by) is on this image. The dark area to the right of the rover looks to be easily penetrated and might be worth investigating to see what it represents.I personally am not in a hurry to get to Victoria because I don't see any access to the crater, so what do we do then.
