I went to Mt Teide twice as a teenager - it's an astonishing, barren, beautiful place - the plateau on the top of Tenerife from which the final tip of the volcano spikes upwards.....
Anyway - I spotted this vid at the BBC http://news.bbc.co.uk/1/hi/sci/tech/4767403.stm Doug |

Coming back to the design of the rover itself: when I sent this news about testing Pasteur (ExoMars rover) to a Polish friend of mine, he asked me if Pasteur is going to go faster or slower than the MERs and are they really going to power it only with solar energy instead of putting a few RTGs into it. I do realize speed is not essential in such missions but that kind of corresponds to overall range and travere times and the RTGs would be important for the total duration of the mission and number of sols covered... I would be terrribly thankful if someone got the answers...

Karolp: I don't think there's any ESA member state with RTG technology - SFAIK, only the Soviet Union and the US developed such things. I don't know if the Russian Federation has kept the technology going - and the US seems to have to scrabble around for the radioactives! Seems strange, considering how many nukes there are on Earth, that one of the few not-very-military uses should be so hard to come by...

Bob Shaw Russian RTG's weigh much more per watt of electric power generated than their U.S. counterparts. That and component lifetime were the reasons the Soviets never launched an outer planet mission. A Russian RTG would surely break the mass limits for Exo-Mars rover. |

Here's that ESA PR shot, but with ExoMars moved to the fourth planet:
