Thanks to mhoward's processing and my running it through ImageJ - we have a 16bit Tif for those that like such things. It looks like the attached 1/4 size JPG and is found HERE - About 26 meg

I have tweeted the appropriate people smile.gif

One could explain the solar array moving with wind - but not the whole scene. Perhaps strong winds have been moving the rover around ever so slightly and the array as well. 120deg FOV on Hazcams - a 3 pixel shift would be the rover moving by 0.3 degrees.

There are 24 CCD's - each with two 'havles. Each half with two channels

As text loaded straight into ImageJ - it's lat long alt - there's a header that describes it once unzipped (I used 7zip) - you may have it muddled somewhere.

The best analogy I can come up with is the values in HRSC Dems - which a guy on HRSC kindly wrote an IDL routine to churn into something usefull

QUOTE
hrsc2tif
A tool to convert HRSC PDS- or VICAR-format files to TIFF format.
For DTMs, the 16-bit signed integers are converted to 16-bit unsigned integers by adding 32768.
Limitation: only converts files small enough to be read into RAM.
The software requires installation of the free IDL virtual machine, and runs on all common platforms.


This data set is in km if i remember, so it would need to be multiplied by 1000 first - than then have the negative value of the lowest negative altitude added (i.e. if the lowest is -1580 metres, add 1580 to make them all positive values starting at 0)

To be honest, just a raw array of values normally can be convinced to work with ImageJ or Photoshop.

Well - I managed to look at the resulting file - after a header it's lat, long, alt

I don't have anything I know of that can turn that into something usefull for me, such as a high bit png/tiff/tga etc etc.

That's copyrighted by the broadcast company that built the camera I believe - so no. The release specifically states

QUOTE
The position and time of movie images (only catalog information. HDTV movies can be seen on the JAXA digital archives and YouTube site


I managed to buy an import of the blu-ray disk they did and it's worth it for the 15 or so minutes that's included, but they've taken hours and hours of footage since then.

The question for me is - what to do with a .sl2 file.

First thing I wanted was TOPO data - and managed to get through registration, data search - all worked. Got my email with an FTP link for the 400 meg data file.

Download 4kb/sec.

I'll try again later - I wonder if it'll be mirrored by the PDS themselves.

(100 - 150kb/sec now)

Pioneer 10
QUOTE
The last successful reception of telemetry was on April 27, 2002; subsequent signals were barely strong enough to detect. Loss of contact was probably due to a combination of increasing distance and the spacecraft's steadily weakening power source, rather than structural failure of the craft.
The last, very weak signal from Pioneer 10 was received on January 23, 2003, when it was 12 billion kilometers (7.5 billion miles) from Earth.[8]
A contact attempt on February 7, 2003 was not successful.
One final attempt was made on the evening of March 4, 2006, the last time the antenna would be correctly aligned with Earth. No response was received from Pioneer 10.[9]


Pioneer 11
QUOTE
The spacecraft has operated on a backup transmitter since launch. Instrument power sharing began in February 1985 due to declining generator power output. Science operations and daily telemetry ceased on September 30, 1995 when the RTG power level was insufficient to operate any experiments. As of the end of 1995, when its mission ended, the spacecraft was located at 44.7 AU from the Sun at a nearly asymptotic latitude of 17.4 degrees above the solar equatorial plane and was heading outward at ~2.4 AU/year (11.6 km/s); this is the lowest velocity of the five spacecraft now escaping the Solar System (Voyagers 1 and 2, Pioneers 10 and 11, and New Horizons). [1]
Earth's motion has carried it out of alignment with the spacecraft antenna. As the antenna cannot be maneuvered to point back at our planet, it is no longer possible with current technology to establish further communication from Earth with the probe.

It's the weekend. You'll rarely see drives on a Sunday, if there was a drive on Friday.

Without a drive on Friday - then they can plan a drive scheduled for Sunday after remote sensing on Friday and Sat. But if you drive on Friday- you don't get post-drive imagery in time to write a sequence for the Sunday.

Sharon is the queen of such scheduling - but I think I've got it right.

They're formatting the flash today - something they last did back on Sol 32. smile.gif

Since then - I've reformatted MY main workstation about 10 times.

The photographer wanted DEPTH and PERSPECTIVE - so I was standing in Aberdeen, Stu was standing in Carlise, and the Sun was 4 microns from the front of the lens.

A signal from MPL is a very very unlikely scenario.

A signal from PHX is just an unlikely scenario.

The last HiRISE image of PHX was not the height of summer so we don't know how visible the chute, backshell and heatshield will be after the ice has fully retreated.

Via HiRISE on Twitter (always superbly informative, fun, and quick) that image was the last before the extended safe mode we're still in with MRO. So it'll be some time before we get a better 'springier' picture sadly.

That they went straight over that little cobble field/flatish dune says something about their confidence with the vehicle and driving. Regular 70m drives are not to be sniffed at.

IF we can get through the next 2km before years end (70ish days) we'll have done DAMN well this year I think.

Since Block Island - 43 Sols, 1.2 km Average of 28m/sol even including the science stops, restricted sols etc.

That's not too shabby at all.

The reasonably good driving terrain starts in another 2km or so - the sublime driving terrain another 1km thereafter.
We're then 3km from Endurance 2.0 (I fancy calling it Aurora - have we had that one already? It was the ship that did the other side of the Antarctic from Endurance during Shackleton's expedition) in terrain that saw an average 100m/sol in the James Caird days.
Then only another 6.3km till Endeavour.

Yeah - we've still got a ways to go smile.gif

They thought Husband was higher. It wasn't until doing basic trig from the top of it, they discovered McCool to be a few metres higher.

Accuracy would infer they could reliably avoid such a crater if they so wished. They've stopped for a quick look.

Given that the forum started a month after Spirit landed - year, details would be sketchy smile.gif

http://an.rsl.wustl.edu/mer/ - go to Sol summaries, then documents. The SOWG and Miss.Man. documents are very details and cover details for just about everything.

But the two best ways to relive those early days - at to buy and read 'Roving Mars'. And read this http://marsandme.blogspot.com/ All of it. From the beginning.

Not MER related - but an orig book written by the skipper of the Endurance on the Imperial Trans-Antarctic Expedition. A unique perspective on the adventure all the way to South Georgia via Hell and back. Found it in the basement of an old bookshop near Leicester Square while waiting to meet Chris Lintott and Jane Houston Jones.

Very long story smile.gif

I had a go blinking layers, but didn't have any luck - good job on that one. It'll be interesting to see if there were any more pre-safe-mode images. Otherwise we might be in for a bit of a wait for new ones.
