Are we looking at the same thing? Maybe its a perspective thing but these parts look curved across the surface of the imaginary sphere of the wheel surface in your render but straight in the photo.

I can't think of an easy way to estimate the reentry date. However, we know the resistance will climb exponentially as the altitude decreases, and, based on the slope change at the end of that altitude curve, it won't be long. has anyone made a prediction?

Amazing as usual, not that I expected anything less.

The diagonal part of the tread pointing toward the hold down point looks curved in your render, is that right? I could have sworn it was straight and looking at a few images it looks to me like should be.

The thread title is "The SOHO Birthday Comet", but I think a better name would be "The Great Christmas Comet of 2011"


I agree, I added the "2011 W3 (Lovejoy)" subheading earlier today to help identify the thread and have now changed the main title to your suggestion.

I'm sure they have, although I wonder if the rapidly changing Doppler frequency from an orbiting craft is another problem with acquiring a lock using antennas designed to work with craft in deep space?

Have you got confirmation of this Matt? 2728 looks like another runout from the tracking data.

As there are still missing data I haven't tried too hard to perfect this, but the the view is so astounding that I can't keep this preliminary version to myself! wink.gif

That is the start of the Endeavour pan. Those 5 will be joined by 10 more tomorrowsol, and hopefully more next week. All in L257 colour. smile.gif

I haven't done any detailed analysis of how well my drivability maps turned out but it didn't seem to far off smile.gif

I did plenty of eyeballing of HiRISE images coloured with derived ripple size at the time to know that was working well and we now have plenty of experience comparing ripples from the ground with HiRISE to know how those compare so I'm not surprised it worked fairly well.

So by my reckoning the tracking data puts us very close to that hump that we were debating yesterday, right on Botany Bay. This should be spectacular!

climber, expect images at 01:35UTC, too late for me dammit!
