Farewell, little Voyager of Mars. 15 years out of 90 days, talk about a ROI !! :o

It turned out to be 15 years and 28 miles.

One argument for human explorers on Mars in a nutshell.

That's not to take away from the achievement of those involved in the MER program. But even if you assume Opportunity managed to explore a very generous 400 square miles of Mars, it would have taken it nearly 4 million years to explore the whole planet.

In 2009, Principal Scientist of the Mars Exploration Rovers, Steve Squyres was quoted in a Space.com article that feet on the ground could do all the years of work that Spirit and Opportunity over the years in a week.

Both (people and robots) are needed and are effective in their own ways.

Daydream:  An exceptionally powerful dust devil sweeps over Opportunity, clearing off the solar arrays and starting trickle-charging of the river's almost-dead batteries.  Meanwhile back on Earth, someone operating the Greenbank radio telescope turns the scope towards Mars on a whim, picks up a faint signal.  A week later Opportunity is on the move again.   ;)

I worked with Steve on the decadal survey (he's a great manager) and discussed this with him. His comment has really been taken out of context, and it's often used simply as a weapon in the "send astronauts now" argument. It's one aspect of a much larger discussion. Furthermore, there have been a number of automation improvements since 2009. For instance, Mars 2020 can do a lot more autonomous driving than Curiosity, plus it will have (I think) some ability to recognize interesting features as it is driving and call them out. So the machines are getting smarter.

One of the quiet, but significant, developments with Opportunity was the long, straight drives to Endeavour allowed NASA to test autonomous driving.

I can believe that. During a JPL visit last year I saw a demonstration of the Mars 2020 update to the driving system. The rover will be able to navigate its way better than Curiosity. I don't remember all the details, but it's along the lines of Curiosity requires a bunch of commands to go to a location, and if it encounters a rock, it may simply stop and ask for instructions, which can cost a day or more. But Mars 2020 they point at a location and tell the rover to go there and it will navigate around obstacles much more freely on its own. This is also tied into the better vision system. But I'm vague on everything we were told. They did a number of tests in the Mars Yard to have the mockup avoid obstacles on its own.

Addendum: I'm not really telling it well. It's not that Curiosity is dumb when it comes to navigating, or that its software has not been improved over the years. It's just that Mars 2020 will have more capability, which should make it faster.

To clarify, the bottom comic was published in 2010 for Spirit.  The Opportunity tribute has already been posted.

I'm not crying. You're crying.

I don't know if I want Oppy brought home or enshrined right where it is. ...

Yeah, I know. Thank you, Sheldon...

EDIT: I did say Rovers (as in plural).

Yeah, I know it was set in some kind of code and didn't really mean it in an emotional, lonely voice, but damn.... 

My wife was crying. I have allergies.

I am writing an article for my school newspaper on Oppy and it's mission.
How dic the rover die in terms of the clocks scrambleing? Are there any guesses by the team?
