An impossible task? And maybe a not very useful one but...here it goes...

I would really like to establish a link between both rovers, Spirit and Opportunity.
How to achieve it?
Is there a way to find the X marking the spot? Phil? James? Pando?...Anyone?

Is there a way of, through your accurate measurements find a a way to Xitania and X Civitas? The martian ground wher both rovers meet?
How does this work? Nothing really scientific, maybe a mere curiosity but I would like to know where, grabbing both rovers landing sites and drawing a straight line between these and then, taking their current locations, find where the intesection point is located...that is what I would call the Xitania capital, X Civitas...is it feasible? Come on guys...I know that from you there are no impossibles...

Maybe we can this exercise into previous sols and, most importantly, future ones, until the last one of them...then we would have the whole Xitania territory marked, joining the four quadrants and X Civitas would be there, as a capital of a whole unexplored ground...please me!

Ahh, daydreaming of Mars. Perhaps a "daydreaming" thread is a good idea, or, heck, even an entire subforum!

I've certainly dreamt of rover encountering rover. Just imagine a crazy alternate universe where their landing sites had been tens instead of thousands of km apart. Or if MSL were to go to Meridiani...

As they approached each other, one of us here at umsf would be the first to spot one from the other's cameras, nothing more than a single pixel glint of sunlight, a beacon on the horizon. Then, over very many sols, the single pixels would grow, and eventually the rover shape would be recognizable. Finally Encounter Day would arrive, and we'd see the rovers as no overhead projection or simulation could ever show. We'd see them on Mars.

You guys are crazier than this special cookie of yours!

I'm looking only for he interception point nothing more than that!

But we can discuss it...

interception point

That's simply half way around the great circle path between them. But you seemed to dismiss that - seriously - I don't know what you're trying to get at here. Half way between them, or something else. What does a rectangle have to do with it? Both being fairly close to the equator, a great circle route is fairly close to just a straight line on the map anyway.

Spirit is 14.5718 south, 175.4785 east
Opportunity is 1.94 south, 354.47 East

Thus - a point roughly between them is 8.256 south 264.97 east, which is the east end of Noctis Labyrinthus.

If that's not what you're after - then what are you after?

By the way, B2 is only roughly half way between them - if you go the long way around. There's only 2 degrees in it - but the 'shorter' route is to go West from Opportunity and down Valles Marineris - not East between Hellas and Isidis.
