GENIUS ohmy.gif

We've got one at home.

I wonder if you could make a dial? I could get some b'n'w stuff photocopied onto transparancies and then cut it out to fit.

I started a thread about ESA's Press and Public Outreach 'ability' here
http://www.unmannedspaceflight.com/index.php?showtopic=1117

What I may do is put together a more verbose questionare about ESA - compile the findings, perhaps get the BBC behind me ( they'll pick up on anything like that ) and present to ESA saying "look - you're not pulling your weight - we dont mind paying taxes for ESA - infact we do it gladly - but you HAVE to spend a little bit of that telling us what you're up to!"

Well - a helecopter pilot has cross winds to worry about smile.gif

Not only that - he also has to get the payload down on a specific point.

SKycrane can simply hover in any safe place - it doesnt have to drop MSL onto a big red X on the martian surface

Given the sort of imagery we'll get from MRO - I dont think we really need to be able to look 'further' from the ground.

Mars Dead or Alive is fantastic - if you can, get the follow on -called "Year One" or something.

Basically - I think it's like that - but the whole thing will come to a dead stop above the ground and do the skycrane 'thing'

You could always drop out the backshell whilst still on the 'chute I guess - that might eliminate an opportunity for instability

First, the name will never be used outside "crank" circles.


Well - in the same way that I called Erebus ' Albert ' for months - in the absence of a name coming out of the MER team - there's nothing wrong with calling it Ultreya.

I agree with your conclusions on what it might be though. I'm not expecting anything amazing - but there is a cool factor in just seing what's around the corner.

I dont believe there's any skycrane-backshell tether. It would just jetison the backshell like Viking/Phoenix

I've not heard any figures that large. Perhaps 1% of that, but certainly not multiple km's per sol

Payload fairing smile.gif

One of the cunning things about the Atlas integration process is that instead of putting the payload in a canister, taking the canister to the pad, open the canister, put the payload on top of the rocket, get the fairing, and fit it around the payload....

You simply put the payload in the fairing here, then take the whole lot, fairing and spacecraft inside - over to the tower and plop it on top - the fairing acting as a pseudo-cannister protecting the payload.

Using that - you can see that Spirit is FINE - and has been imaging a LOT

444 images in a single sol must be a pancam record - perhaps a lot of EDN images - I dont know - we'll find out soon enough - expect a "1978 images added" on JPL at some point smile.gif

So whilst we're not getting any news from 'home' (sometimes I almost swop my reality so 'home' is where the rovers are biggrin.gif ) we can see that there is activity going on, and data coming home.

Someone more up to speed on site-numbers and drive-numbers could actually see if any driving has gone on as well

They do look a little..er..'vivid' in places.

Am I right in thinking that most of the stuff from the Whale pan did make it into the explor, but not onto the JPL site ?

Given that the 'Legacy' pan from Middle Ground ( near Humphrey ) was taken, downlinked, stitched, and sent to the JPL web team more than a year before it actually ended up appearing on the JPL website - it's not suprising that the Pancam team are doing something on their own.

Lovely pic of the near-complete spacecraft on slide 3, and great shot of the spin test on 41. Sound like everything is on schedule, much better and you'd be shooing MRO out the way to make room at the Atlas LC smile.gif

You look at the cutaway drawing of the launch vehcile and I honestly cant remember the payload being a smaller percentage of the LV - it really highlights just how much energy is required.

If we can achieve a zero descent rate at a given point above the surface, why not try to achieve it *at* the surface with a similar system?


You're going to cake the entire spacecraft in dust, and ask the rocker-bogie to deal with the whole lot at some point as well.

I think skycrane is easily dismissed as mad - but so was the Pathfinder plan smile.gif
