20-year battery lifespan? Why isn't this on Mars?

By | August 18, 2012
I'm not sure if this is too good to be true – but NanoTritium batteries, according to this article, can hold out 20 years under extreme conditions. That sounds like the perfect space backup power solution. I'd love for it to venture into consumer technology too, but it seems too expensive for that, starting at the several thousand dollar range.

    Not enough power for Mars: "The City Labs’ battery produces nanowatts of power; it is not strong enough to power a cell phone or laptop." According to Wikipedia, Curiosity's power plant can put out 125W.

    +Euro Crisis News Overview sure – though with how modular things are these days, I think it's reasonable to expect a backup power cell with this technology on board near-future missions. It's quite useful in terms of powering transmissions during prolongued dust storms. Worse come to worse, the rover can self-amputate.

    Space organisations are pretty conservative so they only use proven technology, and that only after years of testing in space conditions.
    Also, the used in the new Mars rover is from around 2004 or earlier 🙂
