Today is a historic day...eh Sol.
Sol 1281 is the sol that Spirit will beat Viking 2. Yes, that's right, today a solar powered vehicle beat a Nuke in longevity! I say a celebration is in order! |

According to wikipedia info:
QUOTE Power was provided by two radioisotope thermal generator (RTG) units containing plutonium-238 affixed to opposite sides of the lander base and covered by wind screens. Each generator was 28 cm tall, 58 cm in diameter, had a mass of 13.6 kg and provided 30 W continuous power at 4.4 volts. Four wet cell sealed nickel-cadmium 8 A·h, 28-volt rechargeable batteries were also onboard to handle peak power loads. I personally don't believe that at least one of the rovers will live longer than Viking 1 ( the other lander ). |

I personally don't believe that at least one of the rovers will live longer than Viking 1 ( the other lander ). Depends on what you mean by "live". Certainly they might not be able to keep moving for two or three more years. However, even if their wheels fail, they still might be able to act as stationary "weather stations". |
