BBCnews is carrying this update on upcoming changes to the Mars rovers. By using software developed for an Earth-observing space probe, NASA scientists will upgrade the rovers, allowing them to autonomously select data (in this particular case, involving images of clouds and dust devils) and only upload the most significant items to Earth. The systems work very well and have provided significant cost savings on some missions already. With refinement, it's hoped such techniques will make roving space probes to more remote places like Titan possible.
