Nasa (NASA?) has selected Saft, a French company, to develop its next-generation batteries, batteries that will power tomorrow’s rovers, landers, and all sorts of space-related goodies. The batteries will be of the Lithium-ion type, like the kind inside your cellphone (but not the new MacBook Pro—that’s a Lithium-ion polymer.)

What can we expect from these fancy, new, French-developed batteries? Apparently they’ll be lighter, which, as you can imagine, is important when sending items into space.
