I shall watch while playing Motherload, (which is set on Mars)
Uh oh. The pictures are going to be lossy JPEGs which will have artifacts. The conspiracy theorists will have a good time.
There sure are some cynical comments over at the BBC...
Sorry,people who support this are all mad. How much was spent on the lunar missions over the years? And what did mankind gain from it? Can we not get our own planet sorted out first?Who gave NASA the authority to dump more space junk and alarmingly a nuclear device on another planet to fulfill their curiosity?Why go into space?
There will always be the uneducated and the cynical...and worst of all, the uneducated cynical. :-(
NASA Did.Who gave NASA the authority to dump more space junk and alarmingly a nuclear device on another planet to fulfill their curiosity?
Actually, launching an RTG requires presidential approval, DOE approval and USAF approval.
NASA simply asked. They did not do so lightly.
And Glom - the early thumbnails will be lossy JPGs. Later imagery can be losslessly compressed if necessary - but an element of compression is necessary for most imagery simple from a bandwidth point of view. This is true for Spirit, Opportunity, Mars Odyssey, MRO, MEX etc etc.
Example - a complete 360 pan with the M100 Mastcam (1200 x 1200 x 24 bit - ie 34 Mbits) would be approx 630 images. Uncompressed that would be more than 20 Gigabits.
The average UHF pass for Spirit and Opportunity is 50 - 100 Mbits. For Curiosity it might be as much as 250 Mbits. It would still take 40 days of downloading nothing but those images to get that panorama down if you don't compress them. It's untenable.
Conspiracists find 'artifacts' in anything. They find it in uncompressed imagery, compressed imagery, raw imagery, calibrated imagery, push broom imagery, framing camera imagery, map projected imagery, un-map projected imagery. They'll find it in ANYTHING. Oh - and here's a prediction. People have been 'finding' things right at the limit of resolution of Pancam on MER ( just like they 'found' things right on the limit of resolution of SSI on Pathfinder.
I'll bet you people 'find things' at the limit of resolution of MastCAM as well. They're always chasing noise. They're not rational.
Who cares about conspiracy theorists after all? Nobody cares...
Cum catapultae proscriptae erunt tum soli proscript catapultas habebunt.
This Phoning Home: Communicating from Mars video explains (in a slightly cheesy way) how the initial data confirming landing will be received (via Odyssey or the Reconnaissance Orbiter). It says (at about 2'0'') that it will take "several hours" to decode the data.
Why so long? Or do they mean the time to receive the data (I assume it is a pretty low bandwidth link)?
This video also explains that we may not hear about the rover for THREE DAYS in the worst case...
JPL always try to tone down expectations.
Its like Scotty, doubling how long he says it will take to fix the engines.
I clearly remember the first image from Spirit. It had some bluish hue when it was first published
Yes, I think it was probably secondarily photographed from a TV screen and then reuploaded on the NASA/JPL website and this prolly explained the bluish hue. Then this photo was deleted and reuploaded again with no hue. I know what I'm talking about - not talking about color photos or 3D photos
Fair winds Curiosity
Good luck JPL
Or something of the sort.
Your theory is crazy, but it's not crazy enough to be true. - Niels Bohr

Hint: this is at heart a scientific forum, and underneath the fooling around there are some diamond-hard minds hanging about, ready to tear you to shreads. -- Mike Alexander
I will not be watching, in case that causes it to crash aka Schroedinger's Cat
It's the most reliable, robust way of getting every single bit of data that MSL might send. The upside of the Odyssey link is the real-time nature. The downside is that it's more sensitive to drop-outs etc.
Ah, got it. Thanks.
I am personally very excited. Last night I almost couldn't sleep and I was dreaming heat shield separations and parachute deployments all the time... again, and again and again
Going to bed soon and I pray that I will wake up no earlier than 2 hours before landing.

congratulations for the another leg on mars "curiocity-mars lander"
Hey everybody, I haven't posted here in a while, but I wanted to check in because I knew that you guys would have some good info on Curiosity. I wasn't disappointed
I'll be listening to the coverage and hoping for the best. This will be a huge achievement for NASA if it goes well.
