A straight copy of the Beagle 2 science payload wouldnt be a bad move - given time to test and calibrate it all properly.

Totally depends on the strategy they take. If they think "right - that's Husband hill done - lets floor it" - then it could be perhaps as little as 60 sols to get there.

If they do stops at sites en route - you can quadrouple that.

And why the american data realy - is MEX expected to give up in the near future?

America wont supply an EDl system - ITAR makes sure of that.

Well - I see 9 columns of data - which is about as much as they can do in a single sol, so Sol 584 and 585 will see the remaining two thirds being imaged.

Sat up on top of a hill is probably rather condusive to excellent UHF passes - a full 360 degree panorama is about 400 - 500 Mbits.

I have a special lurkdar - a lurker detection machine - and it's off the scale smile.gif

Yesterday - we had 116450 hits, instead of the more usual 50,000 or so smile.gif

That translates into 1500 visits instead of the usual 800ish.

Sorry to repost the whole image, doug can you resize it down please.


Nope sad.gif

One downside of invision is that you can make an image smaller. I may see if V2.1 allows it - as it would be nice to have them at 512 x 512 instead.

Really - you cant focus on the blue ones - your eye isnt clever enough to do 'different' focus on it because it's a different wavelength

Have all three lined up - the blue one just wont focus.

It's very odd - I read it on the internet ( so it must be true ) and had a try myself and it's actually true smile.gif

A bit color change again. I'm still unsatisfied about contrast and conservation of details in my pans, but the (my) clearing of the lens vignetting degrades it always.

I like SCIM a lot - but I have worries over our knowledge of the atmospheric density at high altitudes. We were suprised by the MER descent profiles - and having a play in Orbiter - all be it a very primative simulation - a tiny difference in altitude could make a HUGE difference in the delta-v imparted by the high altitude pass.

Using one scenario - an altitude of 36km sees an incoming spacecraft crash into the surface, 37km breaking into a low orbit, 40k break into a very eliptical orbit, and 41km 'scims' striaght on through.

Of course the planes are very very sexy missions but astonishingly short lived.

I think an orbiter with a creative means to get good downlink to earth would be a sure fire winner if they fitted an electra payload onto it - regardless of its scientific credentials.
