I got my print version of Military & Aerospace Electronics on Monday. The online version is a month behind, so I can't link to this article, just yet.
This article is about integrating components onto the actual spacecraft at JPL in Pasadena. Electronic pieces of NASA's next Mars mission are coming together Quote:

Because it doesn't need wheels to do the science it's designed to do. A grab-bag spot anywhere in the hydrogen-rich soils of the northern latitudes is enough. A rover designed to carry the instrument payload of Phoenix would have to be the size of the 2009 rover, MSL, which will cost more than twice as much.

Which brings up the question, why was Mars Polar Lander a stationary lander?
I think partly it's because it is build by the University of Arizona. Rovers and airbags are typical JPL inventions, not everybody is convinced of their usefulness. For instance, the mobility of a rover comes at a great price, it takes a big piece out of the payload mass. That's why the 2 MER rovers only have that small science package at the tip of a robotic arm. Besides that, Phoenix is not a geology mission, it just looks for water(ice) in the ground. That ice layer should be everywhere in that region of Mars, so there is no need for driving to it. Theoretically, that is. |

Amazing how fast we get spoiled, isn't it? Give'em a couple rovers, and suffenly those stationary landers look like the Model T.
A little thought for y'all remarking about the lack of mobility. Spirit and Opportunity were designed to look for traces of water in Martian geography. They had to be mobile, because quite frankly, no one had a clue where those signs of water might be found, if they were even there to be found at all. With Pheonix, we know what we want, we know where it is, we don't have to go fishing for it, so mobility isn't an advantage to the mission criteria. Please, folks, a little thought before releasing that knee-jerk, alright?
