I'm going to draw a line under the 'technical readiness' debate. People can read the various proposals and figure it out for themselves.

Of course, we have ChemCam as an ultra high res imager - but it's not the same as a pair of matched, zoomable, focusable Mastcams.

You're thinking of the Stardust Navcam. That was a major spares-cupboard raid effort ( Voyager optics and shutter ) - and I don't believe MSSS had anything to do with it.

What's amazing is how hard the tracks are to see in most of the HiRISE image - I can see some leaving Victoria - then they go - then I can pick them up for the last few metres.

According to NASA ( a very serious space agency ) it's out of safe mode as well

Below - details of the hinted at talk I'm giving at JPL in a couple of weeks. Local UMSFers are welcome to come along - it'd be nice if I could give an idea of numbers ahead of time, so if you think you can make it - drop me an email ( djellison@mac.com ) and I'll let those that need to know, know. Sadly, my schedule for the two days I'm in LA is so packed, that I can't really envisage the sort of meet up you guys enjoyed when Stu popped over - but it'd be great to see whoever can make it!

Doug Ellison
Creator and Site Administrator, Unmannedspaceflight.com
Date: Tuesday, March 17, 2009
4:45 p.m. to 6:00 p.m., von Karman Auditorium, JPL

Since the landings of Spirit and Opportunity in 2004 and the rapid web
release of every image they take, an enthusiastic online community of
amateur scientists has formed around the rovers and other robotic space
missions. This community has developed tools, tricks, and techniques to
make the most of every image and track the progress of our robotic
envoys creating mosaics and videos that have been referred to as “bootleg
postcards.”

Space exploration aficionado Doug Ellison is a multimedia producer by day,
and founding administrator of the well-respected "Unmannedspaceflight.com"
forum by night. Join us as he presents a history of the web-faring,
space-data-sharing community, highlights some of its achievements, and
explains why the new way to reach out . . .is to let people in.

Doug Ellison's passion is science communication. In particular, he has a
unique perspective on the outreach activities of the National Aeronautics
and Space Administration and the European Space Agency, and on the
collective power of armchair enthusiasts from around the world who have
reveled in the remarkable science returns from ventures such as the Mars
Exploration Rover and Cassini missions.

As an ambassador for the amateur space imaging community, Mr. Ellison has
given many lectures on the rovers and other Mars missions to schools, local
astronomy societies, and the British Astronomical Association. He produced
Rover Audio Updates with Jim Bell for The Planetary Society website, has
presented to scientists at Cornell University and the Europlanet
conference, has written for The Planetary Report, and has been interviewed
on The Planetary Society’s Planetary Radio program and The Sky at Night BBC
television series.

These events are free. All members of the Campus and JPL communities and
retirees are welcome. Caltech personnel and guests can access von Karman
Auditorium via the external gate.

Thanks for linking to these Mike - they're very good, and quite thorough. What has this done to the Mastcam delivery date? I'm going to make the bold assumption that there's not a chance in hell of the zoom being reinstated.

And that's a good point about the sub-forum name sad.gif Phoenix needs to get stuffed into past missions as well.

Expensive to produce, very little chance of any revenue, a significant amount of work to create, and yes, it's been mentioned and thought of before, but ultimately, it doesn't make any economic sense.

Why would taking the known option - the place where we know we can get onto HP with 5 wheel drive - be a surprise?

There's odometer directness, and chronologic directness smile.gif

After driving east and climbing on the ramp she used on sol 1306 to arrive on Home Plate, she could easily and fast drive on the good terrain of HP and arrive to the south edge where she could find a good ramp (a low-tilt slope) to drive down


That's the plan. If it doesn't work - they'll try the west route.

Even if not pointless - it's a usage of fuel that's not necessary and probably best saved for keeping the KBO window of opportunity as large as possible.

What has irked me is that the media, and even specialist (should-know-better) media have been pushing this as 'liquid water found on Mars'.

No it wasn't.

It was found on Phoenix. Several hundred pounds of metal and wires that expended most of its energy budget keeping itself warm, having blasted the surface with >1kdegC thruster exhausts. Those droplets tell us very very little about Mars. They tell us about Phoenix.

The small bodies node does a great job - bundling stuff into a flyby data set, or a day by day data set. It makes getting the whole lot just so much easier.

Try zipping up a 2 meg RAD IMG from MER. It shrinks - and you get exactly the same data out at the end as well.

You can scrap MEX from your last line. It can't produced imagery at 2.5m/pixel - the SRC channel that it has is out of focus, so it's best imagery is basically the HRSC Nadir Channel.

Also - at 0.6% in 2 years - a further 6 years will allow MRO to have mapped a further 1.8% - for a total of 2.4% at <2.5m res. Add on MGS's 3% (not all of which is < 2.5m/pixel). That's 5.4%.

Where are you getting 10% from?

It would take MRO 20+ years to get to that figure.

Nor is Paolo - he's talking about the ruler tool. And - as far as measuring where there is HiRISE imagery to corroborate the measurements - they're accurate - so, one can infer - it's accurate over the whole planet.

One very simple point that the PDS seem unable to grasp ( at least, several parts of it )

If you've got a data set with a few dozen to a few hundred files in it - on an observation by observation basis - please PLEASE provide them as ZIP's or GZ's or something - a single, compressed file to grab a coherent chunk of data is a massive bandwidth and time saver.

Over the next hour - they're going to hoist the descent stage off the back of the rover. Think sky-crane, but really slowly smile.gif
