Mars Rover's Epic Trek For the Crater Endeavor
Smivs writes "The BBC reports that NASA is to send its Mars rover Opportunity on a two-year trek to try to reach a crater called Endeavour.
The robot will have to move about 11km to get to its new target — a distance that would double what it has already achieved on the planet.
Endeavour is much bigger than anything investigated to date, and will allow a broader range of rocks to be studied. Detailed satellite imagery from the Mars Reconnaissance Orbiter will help pick out the best route ahead; and new software recently uploaded to Opportunity will enable the rover to make its own decisions about how best to negotiate large rocks in its path. Opportunity has just emerged from the 800m-wide Victoria Crater. Endeavour, by comparison, is 22km across."
Well, we'd never have been able to put people there nearly as cheaply, or for nearly as long. We haven't solved the problems of getting people in space for long enough for the journey, keeping them alive, feeding them, and having them inhabit the surface of a strange planet without any real support.
The rovers have been absolute bargain in terms of the cost for the science achieved. And, they give us a lot of the basic information we need to know if we're ever going to put humans there. The value vs cost of the these rovers is not something you can characterize as expensive for what we get -- the initial mission was, what $300 million or so?
I think until we can overcome an incredible amount of technical hurdles, the rovers are still a good idea. Of course, that doesn't mean we shouldn't be trying to develop some of the stuff we'll need for manned missions. Likely we'll need to work on some closer missions and return to the moon before we try to get to Mars in my opinion -- that'll at least let us try to sort out the really big challenges.
Cheers

This is a suicide mission, NASA wanted to shut down the rovers years ago, and the public outcry repeatedly stopped it. Now, if the rover goes on a 2 year drive and dies, what a poor little heroic guy, finally succumbed to the elements. ...
And NASA gets to free all the funds to build newer and bigger and better and
Don't forget, these are the guys that canceled the last Apollo missions for the fuel bill; they already had the rockets, trained astronauts and everything else in place.
I'm aging rapidly, I bought a new game and had no idea if my machine was good for it.

And the money to pay the army that would be needed to build and run the missions. Ending Saturn was a good move. The rocket was too expensive. Replacing it with the Space Shuttle though was one of the worst mistakes NASA ever did.
I did smile at the joke, but I still have a lot of admiration for NASA. I am a brit, and yes I was disappointed when the Beagle 2 probe was lost.
However, I still remember as a kid, I used to be awed with NASA, and its space shuttle launches, etc. As a child it was what I associated America with: space, advancing to new frontiers, etc, and NASA usually was the center of my aspirations. I used to dream of being on a Shuttle, and often felt jealous (in a positive way) for what our friends across the pond was up to.
In recent years, and recent news, which unfortunately put the USA in a poor light amongst some, NASA with their exploits brought back some memories about why I aspired towards America; that "can do attitude".
Sure they have messed up, at times. but space exploration is like that. Their successes usually are just as great.
These rovers were built to run for 3 months. They are running for on their fifth year now. Absolutely amazing!
The official reason of how they underestimated the abilities for the wind to clean the sensors, may be correct, but in this day and age, where items are engineered to last their intended lifespan, whoever designed these things still didnt "cheap out" on the rest of the vehicle.
These are not cheap little radio controlled dune buggy models for use on earth, but self maintaining vehicles that for nearly 5 years have operated in a hostile, largely unknown environment with no physical attention!
So hats off to NASA and JPL. And god speed on the new mission. And thanks for giving this older man a thing something to smile about in these times of drab news.
Have a nice day!
