And to think - I'm giving a talk that includes MGS, Odyssey, and MEX in about 42 hrs time smile.gif

GREAT timing smile.gif

I wonder whether MGS could image the derelicts orbiting Mars - even as streaks - despite their rather uncertain positions? Apart from the mere interest value in finding Mariner 9, say, it'd also sort out the issue of whether or not one of the MER vehicles saw either a defunct spacecraft or a meteor in the sky last year (I forget which one of the Rovers it was, but have a feeling it was Opportunity). It'd be nice to (1) find the old birds (2) backtrack their orbits (3) rule them in (or out) and get a final answer...

Of course, the *first* spacecraft to image another spacecraft in Mars orbit was, er, Mars Express...

...and what a nice photo it took of poor ol' Beagle 2 as it drifted away!

Not wishing to detract from MGS, but the claim to have been 'first' is simply wrong! Now, 'best', 'most technically stunning', 'cleverest' and so forth - no contest! But, guys, you came second...

Since we are picking nits, I might point out that Beagle 2 never entered orbit...

Not to split hairs or anything, but was Beagle technically in orbit? If it was drifting away on a path to entry, then it would have been moving at something less than an orbital velocity.

No, you're still in orbit, it's just that your orbit intersects atmosphere (or even the surface of the planet)!

Nope - Beagle 2 was certainly in orbit of Mars! It was released from Mars Express well after initial orbit was established...

B2 seperated from MEX about 5 days before MEX's MOI actually.

Come to think of this, the Viking craft did enter orbit as an orbiter/lander combination. The landers were only released after many orbits of scouting for landing positions. The orbiters might well have imaged the landers back then.

Viking 1 & 2, and Russias Mars 2, 3 and 5 all entered orbit - and then deployed landers. I dont think any of them imaged the landers after seperation however

Doug:

I thought Mars Express was in an initial orbit when it released Beagle 2?

I'll have a search...

And I'm not so sure about the Soviet vehicles actually entering orbit WITH their landers - I seem to remember that one of the problems they had was that the were unable to loiter in orbit with their landers, but instead released them before entering orbit, which would mean that the landers were in a heliocentric orbit which happened to cross the surface of Mars (via the atmosphere). In any case, they were 'clockwork' vehicles and couldn't respond to changes in the same way that the US vehicles could...
