Makes you appreciate why Squyres, in one Q&A session, said that his number one priority for "what to do different" on future missions is to have a bigger pipe for getting data back to Earth.

Heck -- my cable modem provides me 5 Megabits per *second*. At that rate, I can download 300 Megabits in about one minute.

How much coax cable would it take to set up the MERs with RoadRunner service, anyway...?

Problem is, by now the cables would be tangled up around the Sun, with tragic consequences smile.gif

There have been three images (full resolution not thumbnails) added at exploratorium today. Does that mean its fixed now?

I've done some extensive Googling, and can't find a single reference to Odyssey going into safe mode this last week. Nothing whatsoever at any of the NASA or JPL websites. The only thing Google picks up on search phrases "Odyssey" and "safe mode" are articles on the spacecraft being affected by the huge solar flares of a couple of years ago.

So, 1) does anyone know the real story and what the Odyssey team thinks might have happened, and 2) why the heck isn't *anyone* reporting on this?

The only reason I know anything is because of the impact on MER planning, and I haven't heard anything new since Monday morning. I'm wondering the same thing as you.

Just a quick mention, with regards to the importance of Odyssey's use as a relay.

MGS did support some relay operations early on in the mission, but it appears that it is unable to do so right now.

MGS status report

Back on July 21, 2004 in the above status report:
QUOTE
MGS will finish its UHF relay support for both rovers tonight (local) at the beginning of the UTC day 04-204 (7/22/04) when it enters the Beta-Supplement mode of operations. MGS enters this mode of operation whenever the Earth Beta Angle decreases to less than 43 degrees in order to avoid the HGA obstruction discovered in April 1999.

And, as of the last update, it is still in Beta-Supplement mode. So, if Odyssey can't downlink data to Earth, they lost the primary and at this point only alternative to DTE transmission from the rovers of images/data. Lets hope this gets fixed soon, this would be a huge blow to the revitalized rovers.

Yikes....this is starting to sound REALLY bad for the MER mission. Without the Odyssey UHF link, the rovers are practically crippled. We're currently down to 1 or 2 pictures per day sad.gif Im surpried there hasn't been an official statment from JPL on this too..

I'm quite disgusted by the lack of information from JPL to be honest

I'm sure odyssey will be back up and relaying shortly - but that it's a 5 day old situation and we still have no proper news is a disgrace.

Then again - why would the break the 2 year 6 month tradition of not giving a single Mars Odyssey status update http://mars4.jpl.nasa.gov/odyssey/mission/status.html

If this is a bigger problem than just a small safing issue - then we're in trouble. I would hope that ESA would bend over BACKWARDS to assist with MEX given the enormous effort by JPL and MSSS in relaying and imaging attempts for Beagle 2.

.....it seems the people that use and read this message board are the only ones aware of the problem outside NASA blink.gif Quite a few news articles about the 18 month extension though......

If anyone wants to poke around somewhere they probably shouldnt be...


http://mgsw3.jpl.nasa.gov/seq/odyseq.html

there might be something in there somewhere smile.gif

I've got to spend the rest of the day on the wonderful M1 visiting Watford - but I'll be chasing this topic VERY hard tonight and sending emails to appropriate places.

I did find this though...

April 1st was DOY 91 - so that last uplink was, I believe, 21:26 April 5th - i.e. late last night.

Well - that would have been about Feb 10th smile.gif

If they run spacecraft like most people write software or name 3d objects in animation - there's some comedy variables in there smile.gif

Ah, I misunderstood the dates. I get it now.

And I would *never* use use "foo" as a placeholder in code wink.gif
