Mars Rover Rolls And Turns
hcg50a writes "MSNBC reports that overnight, 'the golfcart-sized rover cut the final cord tying it to the landing platform that it came in on 10 days ago, then backed up about 10 inches (25 centimeters) and turned 45 degrees. These were the first maneuvers planned in preparation for having Spirit roll 10 feet (3 meters) down a ramp onto the Martian surface on Wednesday night or early Thursday morning.' The NASA Mars rover website has complete animations from numerous cameras of the 45-degree turn. Driver training was never this cool!"
Drivers ed was never this slow!
Looks like they're using linux. Anyone know which GUI?

Sorry if this is a stupid question.. But why does it take so long for things to retract, the rover to move, etc etc. Obviously they want to be careful since they can't very well say "oops. pick it up and let's try again", but it's taking days for it to just move off the pad..
At least at NASA the backseat drivers are qualified enough to give criticism.
If NASA failed this driving test it would be huge waste of resources. How could they ever live it down? Imagine the headline:
"Rover drives off the side of ramp, breaks off two wheels, and a solar panel."
And the story afterward!
"Felix Milton man in charge of rover navigation watched in horror as the picture feed reached earth. "The rover wheel slipped off the side of the ramp due to some... er.. martian dust," Milton reported. All in all the rover took a five meter trip, and then reported fell 25 cm to the unforgiving martian ground. NASA spokesmen report the trip took 8 agonizing minutes to reach its conclusion. "
Ahh well I hope its fun for them, expensive remote control toy if you ask me. I hope we get solid answers for the questions this project was sent to investigate.
But why does it take so long for things to retract, the rover to move, etc etc.
OK, this is a fair question. Here are four big reasons.
1. As soon as it disembarks, there are hundreds of new risk factors that come up. So they want to make sure that if anything fails (e.g. airbag catches a wheel and knocks it over, breaking off the high gain antenna), at least they've gotten something for their incredible effort.
2. They ARE conducting scientific experiments while it is safely on the lander. It is furthermore slightly elevated and able to take panoramic photos from a position it will not again regain when on ground level.
3. Getting off the lander is DELICATE. There is a ~10 minute communications lag, which means ~20 minutes to give a command and see the results. This means everything must be done very carefully and very cautiously to make sure each minor step went off perfectly.
4. If they did it quickly and something broke, every "genius" on the internet would be saying how stupid NASA was for rushing ahead and how they never get anything right and were just trying to get publicity and blah blah blah blah blah. So let them do it the right way so the mission is a success.

Spammers Using Mars Rover as Relay
"NASA engineers first became aware the issue when the images of the Martian landscape from the pancam started to resemble hot young girls"br>
"NASA promised to track down the people responsible. "Please send to us any spam you receive originating from the '@spirit.mars' address, so we can track down the offending spammers. Don't forget to include the pictures too,"
Before you're shocked and appalled for NASA technicians giving quasi-religious names to scientific equipment, maybe you should read how NASA came up with these names.
:P
And I quote from the winning child's essay that named the rovers:
I used to live in an Orphanage.
It was dark and cold and lonely.
At night, I looked up at the sparkly sky and felt better.
I dreamed I could fly there.
In America, I can make all my dreams come true.....
Thank-you for the "Spirit" and the "Opportunity"

Heaven forbid that NASA names the rovers after the things that make America great. Oops...probably shouldn't have mentioned Heaven

And then...
"Oh shit, I just ran over a Beagle"...
Dude, this thing has fourwheel drive! Can I go offroad? Please?"
I'd say this is about as far "off road" as you're gonna get.
Yeh - because NASA would never fail to use metric units would they?
-- IANAL, BIPOOTV
Beagle...Rover...
Great. We're not on Mars yet and it's already gone to the dogs.

And before anyone says; it's unlikely that just tilting the panels will shift it as it'll be held in place electrostatically. Also, there aren't any "wipers" - more possible failures and the dust is likely to scratch the panels if wiped.
And finally; the data gathered in those 90 days will take years to process and study anyway.
