Very nice detail. Any idea of the depth of those pits?


Approx 300m across and 180m deep - I did the trig on the distance from the side to the shadow using the illumination angle some time ago.

I've seen videos of basically, small rivers carrying quite large rocks straight over someones driveway about a mile outside of JPL. I had no problems ( I'm a few miles from the foothills ) - but it had a lot of us on edge. About 11 inches of rain in 5 days all told. That's about 1,400 tons of water over a football pitch.

Meteo-nurd factoid. Per year per sq Km.... the UK has more tornadoes than the USA.

If there's thumbnails to color the Navcam with, it means the full Pancam is on the way (as is the case with this observation)

The UMSF book idea has been around for pretty much as long as UMSF has been around.

Well - he's tweeting about it smile.gif

We're getting drowned over here in LA - something like 210mm ( 8.25 inches ) of rain in the last 4-5 days. Most of it in the last 45 hrs.

The only reason that treatment made sense here is that we're still waiting for the full pancam frames to come down. Once they are - that composite of thumbnail-color over full frame Navcam will be rendered redundant by the full frame Pancam color.

When will they be able to transmit such a huge batch of photos?


In the exact same way they've done for nearly 7 years as demonstrated here
http://pancam.astro.cornell.edu/pancam_ins.../panoramas.html
or here http://pancam.astro.cornell.edu/pancam_ins...nt/mosaics.html

Over the next few sols, as they do every time they take a large mosaic.

Exactly what it is - unless you've spent 7 years with your eyes closed, it's a familiar sight to every MER fan clicking through an MMB update.

They bracketed the values into big ranges - and each range got a different color

I think this - http://mm04.nasaimages.org/MediaManager/sr...mp;profileid=21 - or something VERY similar to it is in the hall of the Media Relations offices at JPL. I'll gigapan it one day - you can read every single number off it.

The normal refresh times for the image archive at the Exploratorium.

If we know the images are on the ground ( which we do) then the next scheduled refresh time for the Exploratorium ( something we're used to via experience ) will mean we get to see the images.

Oh - I totally agree - it makes perfect sense to include a copyright .

Might an appropriate compromise be to say that imagery hosted at ASI is available for use under the CC licence unless otherwise stated (see individual images for details)

Forgive my ignorance, but outside of photographing objects with your own camera, is it even possible to copyright images you have only composited from something such as the PDS? Maybe I'm just confused and assuming most are not talking about composite images.



The creation of mosaics, composites, anaglyphs, projections and other treatments of raw data constitute the creation of an original work - and as such the copyright for this derived imagery lies with the individual who created it. Copyright does not have to be explicitly stated to be enforcable.

Remember - Rosetta isn't doing a 12km/sec flyby of Chary-Gary... it's a rendezvous and orbit... and orbits around small bodies are amazingly slow.

An ejection should be easily identifiable by a reaction force pushed back on FASTSAT by the spring in the P-POD. If that happened, but we've still not heard from NanoSail-D - then that's bad news.

. Again, Elsevier wants you to pay for it, and the pdf is too large to post here (1.5 MB).


Then you would be breaching the T's and C's of Elsevier to share it here.

I distinctly remember there being a BIG folder of images from an MER ORT being hosted in the same directory structure as the Spirit and Opportunity images at the Exploratorium - but for the life of me I now can't find the.

Anyone still got the old URL or were they lost when that server had problems?

There's a limit on the data rate that can be sent back to Earth, and a limit to the value of increased resolution scientifically.
