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."
