Mars Rover Upgraded 132
MrShaggy writes "According to a BBC article, NASA is upgrading their MARS rovers. The upgrade will allow the rovers to sift through the pictures of dust-devils, decide which is the most appropriate, send it
back. 'Clouds typically occur in 8-20% of the data collected right now,' Castano said. 'If we could look for a much more extended time and select only those images with clouds then we could increase our understanding of how and when these phenomena form. Similarly with the dust devils.' The article also discusses upgrades to the Mars Odyssey. They plan to make it self-reacting to events on the planet as they are happening."

Here's the rub. Spirit and Opportunity were only expected to run a couple months. Intended is a whole other word. They were built with the idea that they could conceivably last this long but the mission profile (and all the press releases) were put together with the expectation that they'd last a couple months. It was the closest thing to a gaurenteed win NASA could do.
Think of it this way, if GM marketed the H2 as getting an "amazing 2 miles per gallon!" customers would brag about how their H2 actually gets five times that number, instead of complaining about only getting 10.
Don't get me wrong, the mars rovers are an amazing accomplishment and a feather in the cap of the "new" NASA. But somewhere along the line there was a choice that needed to be made; Either completly revamp the way NASA does business and eliminate the top-heavy "Office Space" culture of twenty managers for every one engineer OR build small & cheap to minimize failure while lowering the expectations for the missions being planned, ensuring an "artificially" high sucess rate. One of these choices is good for NASA long term. The other can be good in the short term if it help eliminate the problems that need to be addressed by the first solution. It can be a bad thing if NASA decides to stay the course and be happy with writing missions that have a lowered standard of success.

If there is any truth to those statements I have read elsewhere, I have to be a bit worried. Ada is known to be a rock-solid language for developing mission-critical software. Even considering the Arianne-5 failure, it's still more reassuring to know that a software system is developed in Ada than Java.
I also believe that Sun's implementation of Java does not allow for it to be used in mission-critical systems. If it is indeed true that a switch is being considered, they would likely have to write their own JVM, or at least use a non-Sun one.
